BTC steel plate

1.

Green axis: the strongest sense of paragraph, click sound and mechanical sense. It is the representative axis of mechanical keyboard. It needs to press down 2.4mm to trigger. The typing rhythm is full, but the sound is loud and noisy. The pressure gram is 60g

black axis: the paragraph feeling is the least obvious, the sound is the least, and it forms a sharp contrast with the green axis, which can be triggered by pressing down 1.5mm. Some people compare it to cherry's summer. Whether you want to get quick or slow input, black axis can handle it freely, and typing games are suitable

tea axis: compared with the green axis, the sense of paragraph is much weaker, and compared with the black axis, it is not a straight up and down feeling. It can be triggered by 2mm, which is a luxury mechanical axis. The tea shaft is the most expensive of the several shafts

Red axis: similar to black axis. But the number of pressure grams is smaller than that of the black axis, starting from 35 and ending at 60 (the starting point of the black axis is 40). It is a new axis proced in 2008. It feels lighter and has no paragraph feeling when knocking. It goes straight up and down, and the trigger key stroke is also 2.0 mm, which makes it easier to knock

The mechanical keyboard can be divided into traditional tea axis, green axis, white axis, black axis, red axis, romer-g axis and optical axis. It is because each button is composed of an independent micro motion, so the button has a strong sense of paragraph, which proces a special feel suitable for game entertainment. Therefore, it is usually used as a relatively expensive high-end game peripheral< br />

2. The concept of blockchain, especially in the last two years, has been very popular. Since it exists, it shows that there are still many problems to be solved under the market economy system. For example, how to use blockchain to solve some cross bank clearing problems in global cash management; How to use blockchain to solve the problem of food safety; How to solve the docking of energy market through blockchain; How to make use of the characteristics of blockchain's storability and traceability to widely store and share cases is not a good idea, but a real idea, which has been promoted and initiated by leading enterprises or institutions in various fields
technology focus, security and trading
e to its decentralized characteristics, blockchain is destined to be applied not to minority groups, but to the procts based on the consensus of the general public. At present, because of its security, data network congestion, blockchain capacity explosion and other basic problems, blockchain application scenarios are limited
at present, the layout of blockchain in the market seems to be scattered. In fact, once the basic problems are solved, these closed and fragmented blockchain chains can be integrated into a blockchain ecology. It uses side chain, isolation witness, DAG, cross chain fusion and other technologies, which will not be explained in detail here
with the rapid development of the Internet, it provides a convenient network environment for the development of the blockchain. There is no need to consider the network infrastructure more than ten years ago, and the network can not be popularized. This allows developers to focus on solving the basic security of blockchain network, data storage and other issues. This solution process will not be as slow as the development history of the Internet, but will be solved soon. When crossing the threshold, the development of blockchain will enter the fast lane.

3. Dc06ek is a brand of Baosteel cold rolled enamel steel instead of btc1. It is silly to say that it is electro galvanized ×

4. General btc1, used for washbasin, bathroom, etc. Button four, seven two three, Ba three

5. When btc245 and btc340 steel plates are butt welded, E5015, E5016 welding rods or ER50-6 welding wires are used, so the welding will not crack.

6. E4303 welding rod is used for butt welding of btc245 or btc340 steel plate, and ER50-6 welding wire is used for secondary arc welding.

7. Steel grade, Baosteel

8. 1. The inner liner is made of BT
C
steel plate specially supplied by Baosteel, with a thickness of 2 mm. The European wet lining process is adopted for the inner liner, and the coating is evenly and closely combined with the inner liner steel plate after being baked at 850 ℃. It is named "e + Blue Diamond" series, which means the blue diamond in the air energy instry. It not only reflects the nobility of the proct, but also contains the meaning of long-term rability

2. There is no place to see the finished proct in the inner tank. The inner tank is used as a water storage tank, and there is a thermal insulation foaming layer on the outside. The general thickness is 4-5cm

generally, you can't see the tank proction line in the factory. It's hard to see the tank in the exclusive shop. Of course, if you are willing to dissect the prototype in the exclusive shop, you can see it. But I haven't seen Midea air energy, only a small sample of the bottom of the tank with a big bowl mouth provided by the manufacturer.

9. C≤0.12，Si≤0.05－Mn≤0.70－P≤0.035－S≤0.035－Alt≥0.010

10. It must be what thickness is required
