你知道该如何保证板材环保性吗?

提起板材,大家的第一反应都是不环保。那么,板材的不环保到底体现在哪里呢?其实主要就是基材制作和饰面处理过程中使用的胶黏剂了。工艺简单,原料易取,让尿素甲醛树脂(脲醛树脂),现在是市场上最普遍应用的胶粘剂之一。
Mention plate, everybody's first reaction is not environmental protection. Then, what is the environmental protection of plates? In fact, it is mainly the adhesive used in the process of substrate manufacture and finishing. The process is simple and the raw material is easy to obtain. Urea formaldehyde resin (UF resin) is now one of the most widely used adhesives in the market.
在建材加工中,酚醛树脂(电木)、尿素甲醛树脂、三聚氰胺醛树脂是最重要的胶粘剂。以上三种合成树脂的制造方式,是用苯酚、尿素、三聚氰胺与甲醛进行反应。
Phenolic resin (bakelite), urea formaldehyde resin and melamine formaldehyde resin are the most important adhesives in building materials processing. The above three synthetic resins are prepared by reacting phenol, urea, melamine with formaldehyde.
目前,业内正在积极研发减少脲醛树脂甲醛挥发量的办法,包括改性、改善固化剂等。这些胶粘剂,是大家对板材甲醛非常担忧的主要原因。但是,除了板材外,吊顶中常用到的石膏板、油漆、塑料制品、粘合剂里也都有可能含有甲醛。
At present, the industry is actively developing ways to reduce formaldehyde volatilization of urea-formaldehyde resin, including modification, improvement of curing agent, etc. These adhesives are the main reason why we are very worried about plate formaldehyde. However, apart from the board, formaldehyde may also be contained in the gypsum board, paint, plastic products and adhesives commonly used in the ceiling.
而E0级的板材,使用的则是异氰酸酯胶(MDI),价格昂贵,在生产加工的高温热压过程中,会有一定的污染物散发,对人体有害, 不过成品中这些污染物基本已散发完毕,已相当稳定,相比于其他胶合剂来说,确实安全的多。
The E0 grade plate is made of isocyanate adhesive (MDI), which is expensive. In the process of high temperature hot pressing, there will be some pollutants which are harmful to human body. However, these pollutants in the finished product have basically been distributed and are quite stable. Compared with other binders, they are much safer.
一般来说,基材底料的体积越大,需要使用的胶水含量越少。
Generally speaking, the larger the volume of base material, the less glue it needs to use.
根据市面上的多种板材,我们来对比一下价格,含胶量,握钉力。
According to the various kinds of boards on the market, let's compare the price, the amount of glue and the nail holding force.
所以就每立方米胶水含量来说,实木颗粒板﹤生态版﹤多层板﹤密度板。
Therefore, for each cubic meter of glue content, the solid wood particle board is less than the ecological version.
胶合剂的好坏除了影响甲醛的含量外,另一个影响的就是板材的粘合度。
In addition to affecting the content of formaldehyde, the influence of the adhesive is the adhesion of the sheet.
不好的胶合剂可能前两年使用没有问题,可是过两年板材就会散胶变松,然后开裂变形。所以购买胶合板和纤维板时最好用手敲一敲,如果声音发脆,说明质量良好,如果声音发闷,则表示板材已经出现了散胶的问题。
Bad adhesives may not be a problem in the first two years, but in the next two years the sheet will become loose and crack and deform. So when purchasing plywood and fiberboard, it's better to knock with your hands. If the sound is crisp, it means the quality is good. If the sound is dull, it means that the problem of loose glue has appeared in the board.

看等级
Look at the grade
2001年颁布的《室内装饰装修材料人造板及其制品中甲醛释放限量》国标中,E1的标准是1.5mg/L,E1材料可以在室内使用。E2的标准是5.0mg/L,E2材料必须经过饰面处理后才能在室内使用。我们在购买板材家具时,最好向商家索取板材的检测报告和质量检测合格证等文件。
In the National Standard of Formaldehyde Release Limits in Wood-based Panels and Their Products for Interior Decoration and Decoration Material promulgated in 2001, the standard of E1 is 1.5mg/L, and the material of E1 can be used indoors. The standard of E2 is 5.0mg/L, and E2 material must be treated with veneer before it can be used indoors. When we buy panel furniture, it is better to ask the merchant for the inspection report and the quality inspection certificate.
因为国标没有在环保等级标准里提到E0级标准,所以多数人对E0标准的说法是否正确存在争议。
Because the national standard does not mention the E0 standard in the environmental protection grade standard, most people dispute whether the E0 standard is correct or not.
那么E0级的标准到底来源于哪里呢?
Where does the E0 standard come from?
E0级的板材标准是甲醛≦0.5mg/L,其实是国内商家向日本F3星靠近,从国标地板环保标准延伸出来的,E0在国标里只针对甲醛释放量。
E0 grade plate standard is formaldehyde less than 0.5mg/L. In fact, domestic merchants are approaching Japan F3 star, which is extended from the national standard floor environmental protection standard. E0 only aims at formaldehyde emission in the national standard.
看封边
Look at the edge
封边没做好,板材内的甲醛会继续游离释放,进入室内,对人体健康造成危害。另一方面,板材也容易受潮发霉,脱落,容易刮伤手肘及衣物。优质的封边条是甲醛的保险阀,可以阻止水分侵蚀,防止甲醛外泄,装修美观效果。
If the edge is not sealed properly, formaldehyde in the board will continue to release freely and enter the room, which will cause harm to human health. On the other hand, the boards are easy to damp and mouldy, fall off, and easily scratch their elbows and clothes. High-quality edge-sealing strip is a formaldehyde safety valve, which can prevent water erosion, prevent formaldehyde leakage, and make decoration beautiful.
一般来说,封边的好坏还是由加工厂的技术来决定的。因为机器封边会施加一定的压力,要比人工封边更加紧密和牢固。
Generally speaking, the quality of the seal is determined by the technology of the processing plant. Because the machine edge will exert certain pressure, more tightly and firmly than artificial edge.
