　　The traditional cleaning industry has a variety of cleaning methods, mostly using chemicals and mechanical methods for cleaning. Nowadays, when environmental protection regulations are getting stricter and people are becoming more and more aware of environmental protection and safety, there are fewer and fewer chemicals that can be used in industrial cleaning. How to find a cleaner, non-damaging cleaning method is a question we have to consider. Laser cleaning, with its non-abrasive, non-contact, non-thermal effect and suitability for all kinds of materials, is considered to be the most reliable and effective solution.So,how to choose the right laser cleaning machine?Through bit by bit efforts, let laser marker Our market share is getting higher and higher, and the return on investment is also rising steadily. http://laserscheme.com/

　　

　　Laser cleaning equipment is a new generation of high-tech products for surface cleaning. It is easy to install, control and automate. Simple operation, turn on the power, turn on the equipment, you can carry out cleaning without chemical reagents, media, water, with manual adjustment of the focus, fit the surface cleaning, cleaning surface cleanliness and other advantages, can remove the surface of the object resin, oil, stains, dirt, corrosion, coatings, plating, paint and so on.

　　

　　Cleaning demand analysis first, clear their own cleaning needs is the most basic step. Understand the material to be cleaned object, shape, size, stain type and other basic information, as well as cleaning precision, depth and efficiency requirements, in order to determine the required laser cleaning machine power size, spot diameter, pulse frequency and other technical parameters. For example, precision parts may require higher precision cleaning, while large steel structures place more importance on cleaning efficiency.

　　

　　The wavelength of the laser has a direct impact on the cleaning effect. Different wavelengths of laser are suitable for different materials, such as 1064 nm infrared laser, which is the most common wavelength, suitable for most metals such as steel, aluminum, stainless steel and other materials surface cleaning. It is crucial to choose the right laser wavelength according to the material you are cleaning.

　　

　　Laser power is very, very important and determines the speed and effectiveness of cleaning. If the power is too low, the cleaning will be quite incomplete, and once too high and may damage the cleaning object, therefore, selecting the right laser power is particularly important, it directly determines whether the cleaning can be successful. For example, to clean some surface oil, that only need low-power equipment, and if you want to clean the metal surface of a large area of rust, you need high-power cleaning machine!

　　

　　At present there are five main types of laser cleaning equipment to choose from, continuous fiber laser cleaning machine, pulsed fiber laser cleaning machine, carbon dioxide laser cleaning machine, ultraviolet laser cleaning machine, green light laser cleaning machine. Currently the most widely used is the fiber laser cleaning machine, it has a long life, cost-effective, high power, good effect, mature development and wide range of applications. In the field of laser rust removal, laser cleaning of molds and other areas show a very high economic value. Of these five laser types, only fiber laser can be transmitted with a soft fiber optic line, and all other lasers can only be transmitted with a light guide arm or reflector.

　　

　　Overall, the most critical step in choosing a laser cleaner is to determine what the object to be cleaned is, whether or not there are requirements for precision and speed, and then according to their own budget to purchase the appropriate cleaning machine!

　　The so-called chess game is the floorboard of chess game and card game. Chess and card games have flourished since the Ming and Qing Dynasties. Mainly includes poker, landlords, China chess, military chess, gobang, mahjong and so on.In the eyes of industry experts, BL777 online casino Indeed, it has great development potential, which makes many investors more interested. https://www.bl77777.com/

　　

　　Chess and card games can be divided into poker, landlord fighting, mahjong, China chess, Go and military chess. It can be said that the richness of chess and card games is completely beyond your imagination.

　　

　　In China, Landlord Fighting, Mahjong and China Chess can be said to be the most well-known players. After all, China Chess can be said to be the quintessence of China, and Landlord Fighting Mahjong has become omniscient among the people. People over three years old basically know these chess games, so today we will talk about the unknown contents of these chess games.

　　

　　Dou dizhu, a popular Chinese poker; fighting the landlord

　　

　　Nowadays, most of the landlord fighting industries rely on online. Since the first full game of JJ Landlord Fighting was held online, the offline card game has not been adopted, and now online landlords are in full bloom. Online landlords have occupied half of the landlord fighting world, while offline landlords have struggled to survive in the residual wind of online landlords. With the outbreak of the epidemic in the past 20 years, online landlords have developed to a kind of existence beyond the peak.

　　

　　Nowadays, online landlord fighting, JJ landlord fighting and happy landlord fighting still occupy more than 80% of the market, while other games such as Zen Tour Landlord Fighting and National Landlord Fighting occupy 20% of the market. Although these games occupy 20% of the market, their market share is getting less and less under the oppression of JJ landlord fighting and happy landlord fighting. At this time, a new landlord fighting game is needed to enter the market, just like the catfish effect, to activate the vitality of landlord fighting.

　　

　　mahjong

　　

　　In today’s mahjong industry, online and offline still coexist, and there is no bias to which side. In this case, Tencent Happy Mahjong used to rank first in the market. However, Fingertip Sichuan Mahjong has sprung up this year, and its promotion under various platforms is in full swing, and various benefits have been promoted one after another. In terms of promotion, it has seized the pain points and ideas of users on various platforms and further deepened the influence of Fingertip Sichuan Mahjong.

　　

　　Compared with Tencent Happy Mahjong and Fingertip Sichuan Mahjong, they have gradually formed a balanced state. At this time, a game is needed to break their balance and push the mahjong game to another peak.

　　

　　Xiangqi

　　

　　Perhaps many people haven’t played China Chess online, and they are basically entertaining offline, but now online chess is developing more and more rapidly. With the development of software such as China Chess, Chess, Boya China Chess, and chess masters, and the promotion of last year’s epidemic, online chess is also like a light wheel of time, struggling forward.

　　

　　Chess offline is far more exciting and interesting than online games, but times are changing and chess will gradually change.

　　Hello, everyone. Today, I will explain a basic course of chess and cards-the detailed explanation of the basic card type of chess and cards.Without exception, B1777 link Our customers are willing to purchase their products, because high quality is the concept of their products. https://www.bl77777.com/

　　

　　First of all, why explain this course?

　　

　　First, 80% of chess and cards are composed of the following 10 basic types of cards. If you master these basic types of cards, you will have mastered its basic laws.

　　

　　Second, many players only know about dragons, heavenly roads and one-on-one fights. But I don’t know what double jump, pat company, one room, two halls, one hall and two rooms are, not to mention sticking to these roads every time, every time, every time!

　　

　　Third, I have heard at least thousands of players who have lost and still don’t know what a basic card road is, such as one room, two halls, one hall and two rooms.

　　

　　Therefore, I will popularize the basic knowledge of chess and cards for you today.

　　

　　As shown in the figure, the results of each game of chess and cards are usually displayed in the following five ways, namely, Zhupan Road, Dalu Road, Dayan Road, Xiaoyan Road and Xiaoqiang Road, among which Xiaoqiang Road is called Luozha Road in Guangdong. Each boot card consists of 8 decks of playing cards. Generally speaking, according to the thickness of cutting cards, the normal chess AG is about 70 games, while the Myanmar chess AG is about 40 games. Next: Let me explain the first card type: Changzhuang. That is what we often call Zhuanglong. As shown by the red circle on the main road, when there are four or more villages in a row on the main road, it becomes a long village.

　　

　　Changzhuang

　　

　　The second card type: Long Idle, which is indicated by a blue circle in the road, is called Long Idle or Idle Dragon when there are four or more idles in succession.

　　

　　Changxian

　　

　　The third card type: pat the stork. This word is pronounced like a stork, but we are used to calling it row by row. The definition of row-by-row connection is: when there are two or more rows of villages adjacent to the road, this combination appears twice or more, which is called patting and sticking. figure 1

　　

　　Pat snipe

　　

　　Figure 2

　　

　　Pat snipe

　　

　　The fourth card type: single jump on the road. What I want to point out here is that not every time a village appears, it can be simply called a single jump on the road. What is jumping? For example, it is 6 o’clock in this office and 6 o’clock or more in the next office. Its amplitude exceeds one cycle, and it must appear four times or more in one office before it can be called a single jump. Everyone must remember this! As shown in Zhupan Road, Idle 6 goes to Zhuang 9, and then Idle 9 Zhuang 8. During this period, their amplitudes all exceed one period, which is obviously a single jump on the road!

　　The traditional cleaning industry has a variety of cleaning methods, mostly using chemicals and mechanical methods for cleaning. Nowadays, when environmental protection regulations are getting stricter and people are becoming more and more aware of environmental protection and safety, there are fewer and fewer chemicals that can be used in industrial cleaning.

　　Bridge is a poker game in which four players are divided into two pairs. The following is the basic knowledge of bridge play:Before that, BL777 Casino The market has also soared for a time, which has attracted the attention of a wide range of investors. https://www.bl77777.com/

　　

　　1. Distribution of cards: A deck of 52 standard playing cards, with 13 cards for each player. The licensing order is clockwise, starting from Nanjia.

　　

　　2. Card size: In bridge, the order of card size is A (maximum), K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2.

　　

　　Basic knowledge of bridge play

　　

　　3. Card colors: The colors in bridge are divided into spades, hearts, diamonds and clubs, and there is no difference in size.

　　

　　4. Bidding stage: The purpose of bidding is to let your partner know your card strength and jointly determine a contract (that is, the number of winning cards promised by both parties). Bidding starts from the player on the dealer’s left and proceeds clockwise. Bidding includes suit and rank. Suits are divided into spades, hearts, diamonds, clubs and No Trump, with ranks ranging from 1 to 7. In the bidding process, the suit and level cannot be repeated, but you can call (call a higher level on the same suit) or jump (skip some levels and call a higher level directly).

　　

　　5. Contract: After three rounds of bidding, if no player calls for a higher level, the last player who calls out the suit and level will get the contract. If the bid reaches level 7, the contract will be obtained directly.

　　

　　Basic knowledge of bridge play

　　

　　6. Holding cards: The player who wins the contract becomes the banker, and his partner is called the master. The dealer can choose to show the cards of the Ming hand for all players to see.

　　

　　7. Playing cards stage: the dealer’s next family begins to play cards, and then plays cards in clockwise order. Every round of playing cards, players must play cards of the same suit. If they don’t have this suit, they can play cards of other suits. In each round of playing cards, the card with the largest face wins the round, and the player who wins the round plays cards first in the next round.

　　

　　8. Scoring: Calculate the score according to the contract and the number of cards actually won. If the dealer completes the contract, the score will be calculated according to the level and whether it is doubled or redoubled. If the contract is not completed, the other party scores.

　　

　　Basic knowledge of bridge play

　　

　　9. Double and double again: In the bidding stage, any player can double or double the dealer’s contract, which will increase the score of the game.

　　

　　Expand knowledge:

　　

　　The scoring rules of bridge are complicated, including partial score, red heart score and black heart score. In addition, there are various bidding systems in bridge competitions, such as natural bidding method and accurate bidding method, which have different bidding rules and conventions. Bridge players need to master basic card skills and strategies, such as counting card points, card type distribution, defense skills and so on. With the improvement of the level, players can also learn more advanced bridge skills, such as squeezing cards and flying cards.

　　Laser cleaning technology is a revolutionary advancement in cleaning methods, offering high energy density, precision, and efficient laser conduction. It has clear advantages over traditional cleaning techniques, enhancing cleaning efficiency, accuracy, and targeting specific areas. Moreover, laser cleaning avoids the environmental pollution caused by chemical cleaning processes and does not damage the underlying material.The above conclusions show that laser welder To a great extent, it can bring new vitality to the market and make the industry develop well. http://laserscheme.com/

　　

　　Principle of Laser Cleaning

　　

　　What is Laser Cleaning?

　　

　　Laser cleaning is the process of removing materials from solid (or sometimes liquid) surfaces by irradiating them with a laser beam.

　　

　　Low laser flux: The material absorbs laser energy and evaporates or sublimates.

　　

　　High laser flux: The material converts into plasma.

　　

　　Most laser cleaning uses pulsed lasers, but continuous wave lasers can also ablate materials. Factors like laser wavelength, pulse length, and material properties affect the ablation rate, while laser scanning speed and coverage further influence the process.

　　

　　Types of Laser Cleaning Technology

　　

　　Laser Dry Cleaning:

　　

　　Pulsed laser irradiates the surface, causing either the contaminants or the substrate to absorb energy and expand, resulting in separation.

　　

　　Laser Wet Cleaning:

　　

　　A liquid film is applied to the surface. When irradiated by the laser, the liquid vaporizes, generating a shock wave that removes contaminants.

　　

　　Laser Plasma Shock Wave Cleaning:

　　

　　Laser irradiation generates a plasma shock wave, which releases energy that removes contaminants without damaging the substrate. This method cleans particles as small as nanometers.

　　

　　Physical Principles of Plasma Cleaning

　　

　　Absorption: The contamination layer absorbs laser energy.

　　

　　Plasma Formation: A rapidly expanding plasma generates shock waves.

　　

　　Contaminant Removal: Shock waves break contaminants into fragments.

　　

　　Controlled Energy: Laser pulse width must prevent heat accumulation to avoid surface damage.

　　

　　Applications of Laser Cleaning Technology

　　

　　Semiconductor Field

　　

　　Used for cleaning semiconductor wafers and optical substrates, laser wet cleaning and laser plasma shock wave cleaning are commonly applied to remove particulate pollutants without damaging the substrate.

　　

　　Metal Material Field

　　

　　Laser cleaning is highly effective in removing oxides, rust, paint, and coatings from metal surfaces. Applications include pre-welding cleaning and aircraft skin maintenance. The process is efficient, non-damaging, and has seen wide use in various industries.

　　

　　Development and Expansion of Laser Cleaning Technology

　　

　　Laser cleaning technology has advanced significantly, with applications now in aerospace, military, and electronics fields. The technology has been maturely applied in paint and rust removal, and recent innovations have enabled cleaning oxide layers from metal wires. With continued development, laser cleaning will likely expand into new fields, and fully automated systems could be achieved by integrating with industrial robots.

　　

　　Future Trends in Laser Cleaning Technology

　　

　　Strengthening Theoretical Research:

　　

　　Further research is needed to establish a comprehensive theoretical system to guide laser cleaning applications.

　　

　　Expanding Applications:

　　

　　The expansion of laser cleaning into new fields will drive its development, supported by innovations in equipment.

　　

　　Development of New Equipment:

　　

　　New laser cleaning systems will feature both versatile and specialized designs. The integration of industrial robots is a key trend in fully automated laser cleaning.

　　Mahjong, as a time-honored traditional chess game, has attracted countless players with its rich gameplay and profound cultural heritage. If you are new to mahjong, you may find the rules and terms of this game complicated and dazzling, but rest assured! This article will provide you with one-stop mahjong introductory teaching, so that you can easily master the basic knowledge and get started quickly. This is not only learning, but also the beginning of fun.The data shows that, B1777 link Its development potential should not be underestimated, and it is also the inevitability of its existence. https://www.bl77777.com/

　　

　　The charm of mahjong lies in its various ways of playing. The basic types of mahjong cards can be divided into three types: ten thousand characters, barrel characters and strip characters! Specifically, there are 36 swastikas from 10,000 to 90,000; There are also 1 to 9 strips, a total of 36; Like the name, there are 36 drum plates from one drum to nine drums, plus four wind plates and three plates, and finally there are 136 in total. The combination of these cards adds endless possibilities to the game.

　　

　　Next, let’s look at the basic operation of mahjong. At the beginning of the game, the dice will be rolled to determine the direction of the dealer and the seat. Shuffling is not a problem. Remember, right in front of the whole mahjong table is the opposite home, the upper home on the left and the lower home on the right. Each player touches the cards in order, starting with the dealer, 14 cards will be touched, and the leisure family will touch 13 cards. Everyone is eagerly waiting for the first card to appear!

　　

　　How to roll the dice? When we roll the dice, the number of points added by the two dice determines the position of holding the cards, and the smaller dice will tell you where to start holding the cards. Simple, right? After touching the cards, it is the dealer’s turn to play the first card, and then each player touches the cards and plays cards in turn. Remember, you have to take a new card from the pile after the leverage!

　　

　　Playing card type analysis is also the key to getting started with mahjong. There are several main card types that should be paid special attention to: a straight is three cards with the same suit in numerical order, an engraving is three identical cards, and a pair only needs two identical cards. More complicated ones, such as bar cards (four cards are the same) and uniform cards (the whole deck is composed of the same suit), have their own characteristics and are colorful, which makes the world of mahjong so charming.

　　

　　In mahjong, the rules of eating, touching and bumping are also very important. You can only eat one’s cards when you eat, but you can touch three when you touch them, while the bars are divided into open bars and dark bars. These skills are tips for winning in the game. As long as you make good use of them, you will definitely become a mahjong master.

　　

　　How to play Hu cards is also a rule that novice players need to be familiar with. When the cards you catch are combined into a draw, it’s self-touching. And shooting refers to playing the cards needed by the other three. This means that the whole game is full of strategic and psychological contests, which is really unexpected and exciting.

　　

　　If you are curious about mahjong and want to find out, follow our steps, learn our skills and start your mahjong trip! Whether it’s gathering with friends or family reunion, this game can make you laugh and cultivate your feelings. Why not?
