Q:Which plate is not easy to swell, mildew?

Simi 3D laser board, edge strip and finishes 360 ° perfect package core board, the core of the super seal protection, so that water can be non-porous, greatly improve the moisture resistance of the plate to prevent the door due to long-term in the kitchen temperature and humidity The environment of water swelling and mildew, double cabinet life.

Q:How to distinguish between true and false Qingdao wood of the big core board

Go to Qingdao wood shop to buy, E0 level white willow face is very good, no seam and radiation Tong, grasping nails, no deformation,

Q:What kind of plates are used for building models? In addition to the abs board kt board

With snowflakes

Q:Now I have to come up with a E1 level test report, but I want to buy E0 level, but the staff of Loulan Ya said that there is no E0 level of this concept. Is this true? Please industry experts to answer the next

There are some brands on the market in order to put forward the concept of E0 level, in fact, E0 level is not a regular national testing standards in the level. Since this 'E0' logo is easily confused with the 'E1', 'E2' standards, it is often used by some businesses to mislead consumers. Europe will be divided into three levels: formaldehyde content less than 10mg / 100g, E2 (formaldehyde content less than 30mg / 100g), E3 (formaldehyde content less than 60mg / 100g). Only to obtain E1-level certification was known as green building materials, the human body without any harm. National standards for particleboard is 30mg / 100g, this standard is still several times lower than the Western countries. China's current formaldehyde content of wood products E1 grade, E2 level testing standards, has been the latest reference to the latest European environmental standards, manufacturers and businesses if the real standards, can ensure that consumers are healthy and safe. In other words, consumers in the purchase of furniture and cabinets only look for E1 or E2 certificate can be, do not be "E0" or "super E0" logo flicker. In fact, the best level is the European E1 level, when they buy a certificate to buy, the so-called E0 is just a hype gimmick, in fact, Europe also E0 level, but also the manufacturers themselves set a level, not formal certification The

Q:The most commonly used gas shielded welding consumables are certainly different from the material being welded. The silicon content and the manganese content in the wire are higher than those in the material. And the sulfur content inside the wire is much lower than the sulfur content of the base material being welded. Here, the role of silicon manganese is in the welding arc, in the welding bath for deoxidation of the chemical reaction, the other silicon manganese infiltration of the base metal can also improve the strength and plastic of the weld metal.

Here, the role of silicon manganese is in the welding arc, in the welding bath for deoxidation of the chemical reaction, the other silicon manganese infiltration of the base metal can also improve the strength and plastic of the weld metal. ??? The metallographic structure of the weld metal is generally a coarse tissue, which is very poor in mechanical properties. The structure of the base material to be welded is generally fibrous forged tissue, and the mechanical properties are much better. However, due to the weld metal into a certain amount of silicon manganese, the strength of plastic have been improved. In general, the weld metal is much better mechanical than the low carbon steel base metal.

Q:Malacca and the big board, fir board which is more suitable for the cabinet? Experienced to talk about it

Currently on the market there is a board core for the fir Glulam, the surface of melamine finishes the board, the overall is also good, should gradually replace Malacca, the price is higher. Now we are talking about environmental protection, any kind of board are graded, there are good and bad. We can under the plate price, different levels of board price difference is quite large, and the other furniture production of the overall process and accessories for environmental protection will also have an impact, like the decorative plate furniture, edge technology, solid wood furniture, paint environmental Type, etc., when we buy the price is on the one hand, their actual needs and cost is king

Q:Are man-made sheets containing formaldehyde?

The so-called adhesive is the main component of formaldehyde + urea = urea-formaldehyde resin, which itself is non-toxic harmless, but due to the different levels of production technology, formaldehyde dissolved in the degree of urea is not the same, the production process good manufacturers , Formaldehyde dissolution can reach more than 98%, but no matter how good your process, there will always be formaldehyde molecules in an unstable state, which means that the man-made plate why contains formaldehyde; that is to say, in a long time Formaldehyde is slowly released as a major factor.
