Can hemp mahjong be washed with water

Machine mahjong can be washed. But don't use washing clothes or detergent, it will demagnetize and fade the mahjong tiles.

Mahjong machine was first invented and produced in Japan. In the early 1990s, a small amount of original products were imported from Japan to China. Because of China's huge market, mahjong machine industry has entered a period of rapid development, forming a huge industrial chain.

Mahjong machine has gradually successfully reformed from the No.30 small brand imported from China to the No.38, No.40, No.46 and even No.52 big brands. When the industry in mahjong machine rose, single-port machines occupied the mainstream, mainly the production of sparrow friends, and then four-port machines occupied the mainstream.

Extended data:

Mahjong machine is divided into single-port machine, four-port machine, eight-port machine and ultra-thin machine according to the way of pushing cards. The characteristics of each machine are as follows:

1, single-port machine: As the name implies, mahjong machine, which has only one card pushing port, sends cards to all parties through a conveyor chain. Because the four ports need to be loaded in turn, the loading speed is slow, it takes about 2 minutes to complete the loading action, and the failure rate is high.

Among the existing types of mahjong machine, the single-port machine appeared the earliest, and now it has been basically eliminated, and only exists in some second-hand mobile phone markets.

2. Four-port machine: There are four card pushing ports, and there is no conveyor chain, so you can play cards with four ports at the same time, so playing cards is fast. Generally 18 seconds to 35 seconds can complete the card action. Through extremely reasonable mechanical design, it achieves the characteristics of stable performance and fast shuffling speed ... Four-port machine has become the mainstream of the market.

3, eight-port machine: eight-port machine just does not have to grab the card. This machine has just come into the market, the quality is not very stable, and the degree of customer acceptance is not clear.

4. Ultra-thin machine: famous for its light and thin appearance. The whole machine gives people a small and exquisite feeling, which is convenient to move, exquisite and fashionable. Equipped with dual-core system, the whole control system consists of two main programs, sensor circuit system and motherboard. When a sensor circuit fails, the control system will automatically switch to the standby system.

After three years of market baptism and technological innovation, the ultra-thin machine is very stable and gradually tends to occupy the mainstream market.

5. Piano machine: it is famous for its outer frame resembling a piano. However, due to the vicious competition in the market, there are still many problems, such as perfecting the foot and other details to ensure the stability of the machine.

6. Folding machine: The desktop can be folded at a 45-degree angle with the feet, which saves space to the greatest extent, but it is a great test for the rationality of the machine structure and the use of materials.
