Q:Wardboard thickness is about how much

Wardboard thickness of the need to reach 18 mm, the thickness of the best plate up to 25 mm, which is like building a house had to bear the same wall, the structure is reasonable to build a solid and stable house.

Q:On the difference between Q235 and Q345 plate and use

Q235 steel is an ordinary carbon structural steel, that the old A3 steel its yield point is 235MPa, tensile strength of 375-500MPa. General use more. Q345 steel is a low-alloy high-strength structural steel, including 16Mn, 12MnV, 14MnNb, 18Nb, 16MnRe, including a class of steel, the yield point of 345MPa, tensile strength of 470-630MPa. Ordinary quality of low alloy steel.

Q:What kind of sheet is it better to do a desk!

Now the desk, if not often need to use tools to characterize things, most generally do not use glass platen or table, because it is in the winter "cold feeling " not comfortable "general now desktop, with polyamine It is best to use a glassy material that can be made of "high light" (high brightness) or "matte" (low abrasive, low brightness) , It is recommended to use "steel flat glass" to do the desktop, this "compressive strength " much better.

Q:High voltage switchgear shell plate thickness

I really switch cabinet manufacturers work I do not know about other units, I know Our unit is 2 to 3 mm or so, the material is Complex aluminum zinc plate

Q:Why do you say that the dew river plate is good?

Up to now, no one in the world has been able to provide E0-level test reports because E0 is a standard rather than a standard for particleboard environmental protection. It can be said that it is in the concept of publicity. Mainly hope that consumers can pay attention to the environmental issues of sheet metal. ???? Lu River is the pride of our domestic enterprises! The ???? Because we have done a lot of cabinets cabinet products export business, we have done in the Procuratorate Lu Shuihe plate testing, the formaldehyde detection value is the unit content of formaldehyde content of 0.425ml, so, from a conceptual point of view, it The detection value is very environmentally friendly, worthy of our business and customer trust. ???? To believe: Chinese goods, no less!

Q:What kind of wood is the water-based material? Environmental protection?

Water-based days is a professional engaged in water-based polymer research and application of high-tech enterprises. "Water-based technology, beautiful China" for the corporate mission, with the world's first water-based wet synthetic leather production line, China's first 100,000 tons of water-based polyurethane production line and China's first harmful chemical substances testing center. Water-based science days not only to create a new era of non-toxic home improvement, but also to promote water-based materials, furniture, synthetic leather and other areas of green environmental protection industry changes.

Q:What is the problem with the plate at the time of picking?

Plate quality, environmental protection, in particular the release of formaldehyde. Generally some brands of plates like Han master, bunny, millennium boat and so on. Product quality is very good, formaldehyde emission also reached the E0 standard.

Q:Welding 1.2 plate should be used in what diameter of the electrode and the current strength?

Welding 1.2 mm sheet, electrode diameter and current strength and other parameters are as follows: ?? ZX7 inverter DC welding machine (with the characteristics of arc stability, compared to the welding machine is more suitable for thin pieces of welding), the use of reverse (ground clamp negative pole, welding clamp positive +) polarity. ?? Electrode: 2.5 mm in diameter (the market is relatively easy to buy, theoretically diameter 2.0 electrode is difficult to buy to, and the price is much more uneconomical), welding current between 65-75 amps. ?? Welding methods and precautions: the electrode as far as possible tilt angle (to avoid the arc blowing on the formation of 1.2 plate burning), the use of rapid spot welding (arc welding), can not even arc welding, or will burn. With a cap to observe the molten pool cooled to less than the welding rod diameter re-arc welding.

Q:What is FR4 sheet

FR-4 is a glass fiber epoxy resin CCL, a circuit board in the substrate, in fact, you should have seen, such as the kind of small game machine to open, inside the green board is FR-4 to do circuit board. FR4FR5 epoxy board by a special electronic cloth impregnated with epoxy phenolic resin and other materials by high temperature and high pressure hot plate made of laminated products. With high mechanical properties and dielectric properties, good insulation properties and heat resistance and moisture resistance, and a good mechanical processing. Application: for electrical and electrical equipment for the insulation structure of parts, also widely used In the PCB test; and can be used in humid environmental conditions and transformer oil.

Q:Home improvement plate which brand the best ah? Environmental protection best?

Like this kind of furniture plate material quality is good, only used to know, Fuxiang plate can be considered a very large enterprise in Hunan Province, and has been a good quality itself, you can personally go to their stores to see ah. Online question is also asked not to experience in order to understand!
