The production of E0 grade plates requires a very scientific and rigorous process. It cannot be mixed with any other non-E0 standard. Even storage should be stored separately, otherwise it will not meet the standard. Now there are mixed E0 grade plates on the market, but the real E0 grade is only a small number, and most of them are produced by brand enterprises. Because to truly reach the E0 level, it needs to be fully controlled from the three aspects of materials, processes and testing. At present, only brand companies have such strength and technology.
Is it E0, first look at the material!
The high-rise buildings are stable and unstable. In the same way, if you want to produce E0 grade plates, you should turn off the good materials. Material refers to the whole of the board, including the substrate, glue, dipped film paper and so on.
It is understood that the commonly used plate substrates in China are paulownia, poplar, fir, Malacca and so on. Except for the content of formaldehyde in the substrate of Malacca, poplar and Chinese fir, the formaldehyde emission of other substrates is less than E0. The reasons for this are mainly limited by domestic wood production technology and technology.
Domestically produced substrates have a relatively high formaldehyde content. There is no way to do this. Domestic production technology is slightly behind, and if there is a process failure, the formaldehyde content of the substrate will exceed the standard. Furthermore, most of the domestic supply of sheet metal substrates are small and medium-sized enterprises, and large-scale brand enterprises produce or import them themselves. However, the formaldehyde content of the imported substrate is also different. Generally, the horse hexamethyl material produced by cold pressing glue can reach the E0 level; if it is made of hot pressing glue, it can not reach the E0 level standard, so not all imported Malacca can reach the E0 level. In order to realize the implementation of the comprehensive EO grade, the fine artisan brand carries out the detection of formaldehyde emission from the raw material substrate, and guarantees the realization of the E0 level from the source.
As for the application of glue is a top priority, it is well known that most of the release of formaldehyde comes from glue. During the visit, Xiao Bian found that except for some small factories still using E1 and E2 grade glues, most of them have E0 grade glue, but they can be stored together with other grades of glue. Is this feasible?
The answer is definitely not good. The E0 level is a very strict standard. It can't be sloppy. It must be stored separately, otherwise it will cause cross-contamination. Let's just say that the formaldehyde contained in other glues is released all the time. If the E0 glue is also in this environment, it will inevitably be polluted.
Is it E0, followed by the craft!
Process is the method and process of manufacturing raw materials into finished products, which can directly reflect the technical level of a company. How many enterprises in China cannot truly achieve the breakthrough of E0 level due to their difficulties in technology and technology. Looking at the current market, brand companies can achieve this standard and continue to be stable.
The various resources accumulated by brand companies for a long time can support the intangible loss caused by this transformation, because the conversion of any kind of products needs to go through the test of dealers, customers, markets, etc., and also requires equipment, personnel, management, etc. Resource coordination. Just like the artisan, in order to achieve E0, the company's internal resources have been re-integrated, and non-E0 grade raw materials, processes and accessories have been reformed or upgraded or directly removed.
Is it E0, finally look at the test!
The detection is too important. The release standard of the E0 level is <0.5mg/L. Only when it is tested at any time can the standard be guaranteed.
Testing, the general enterprise is only used for finished products to reflect the compliance rate. If it is tested at any time during the production process, one will increase the cost of the enterprise, and the other is that the technical requirements are very high. Therefore, most enterprises usually only detect after the finished product or some important links. However, the E0 grade sheet production process needs to be tested at any time, and only the perfection of each link can make the final product perfect.
I really didn't expect that there was such a complicated and rigorous procedure behind the "E0", which required the identification of logs, the manufacture of substrates, the conformity of adhesives and impregnated paper, the specificity of production and the independence of storage. If you are in control, you can't do anything in any way. It seems that the E0-grade plates that are on the market are mixed, we need to be careful to buy them.
It is recommended that everyone look for the brand enterprise at the time of purchase. Brand building is difficult, but destroying it may only require a small thing. I believe that no company dares to use its own brand as a bargaining chip, so the E0 level of the brand enterprise is more reliable.
