如何辨别双扣聚氯乙烯增强管管材性能好坏
How to distinguish the performance of double button PVC reinforced pipe
,“看”外观。
First, look at the appearance.
颜色,好的双扣聚氯乙烯增强管色泽柔和均匀一致,无杂色。(双扣聚氯乙烯增强管主要有白灰绿黄几种,消费者往往认为白色才是更好的,其实颜色并非判断质量好坏的标准, 实际上双扣聚氯乙烯增强管的好坏跟双扣聚氯乙烯增强管的颜色没有任何关系。塑料粒子以白色、透明色(也有已加好色母其他颜色)为主只要加上色母什么颜色都可以生产,色母不会被分解也不会改变PP-R品质,因此单就水管而言什么颜色也没有关系,按国家规定双扣聚氯乙烯增强管要有良好的闭光性能,就这点而言灰色或其他不透光性能的会好一些。但是这样的优势仅在明管安装和管道井内存在,家装的水管全部是暗埋的,所以就根本不存在着灰色要优于其他颜色之说。双扣聚氯乙烯增强管完全不透光,伪双扣聚氯乙烯增强管轻微透光或半透光。白色产品一般只能用纯PP-R原料产生,如加回收料、废料、角料生产出来的产品其色泽不柔和也不均匀,而用色母加工的其他颜色产品添加回收料、废料、角料等就不会影响产品色泽。这就是为什么注重品质的以家装零售为主的不少厂家产品都以白色为主 );
Color, good double button PVC reinforced pipe color soft uniform, no noise. (there are mainly several kinds of double button PVC reinforced pipes: white, gray, green and yellow. Consumers often think that white is the best. In fact, the color is not the standard to judge the quality. In fact, the quality of double button PVC reinforced pipes has nothing to do with the color of double button PVC reinforced pipes. The plastic particles are mainly white and transparent (there are also other colors with color masterbatch already added). As long as the color masterbatch is added, the color masterbatch can be produced. The color masterbatch will not be decomposed or change the quality of pp-r. therefore, as far as the water pipe is concerned, there is no relationship between any color. According to the national regulations, the double button polychloroethylene chloride reinforced pipe should have good light closing performance. In this regard, the gray or other light tight performance It will be better. However, such advantages only exist in the installation of exposed pipes and pipe wells, and all the pipes installed at home are concealed, so there is no saying that gray is superior to other colors at all. The double button PVC reinforced pipe is completely opaque, and the pseudo double button PVC reinforced pipe is slightly or semi transparent. Generally, white products can only be produced with pure PP-R raw materials. For example, the color of products produced with recycled materials, waste materials and corner materials is neither soft nor uniform, while other color products processed with color masterbatch will not affect the color of products with recycled materials, waste materials and corner materials. This is why many manufacturers focus on the quality of home decoration retail products are mainly white);
产品内外表面应光滑平整,不允许有气泡、明显的凹陷、沟槽和杂质等缺陷。
The internal and external surfaces of the product shall be smooth and flat, and no bubble, obvious depression, groove, impurity and other defects are allowed.
第二,“摸”质地。
Second, "touch" the texture.
好的双扣聚氯乙烯增强管100%是PP-R原料(无任何添加料)质地纯正,表面光洁,手感柔和,伪双扣聚氯乙烯增强管手感光滑,一般来说,颗粒粗糙的很可能掺和了杂质;
Good double button PVC reinforced pipe is 100% PP-R raw material (without any additives) with pure texture, smooth surface, soft hand feeling, and smooth hand feeling of pseudo double button PVC reinforced pipe. Generally speaking, the coarse particles are likely to be mixed with impurities;
第三,“闻”气味。
Third, "smell" the smell.
双扣聚氯乙烯增强管主要材料是聚丙烯,好的管材没有气味,差的则有怪味,很可能是掺和了聚乙烯,而非聚丙烯;
The main material of the double button PVC reinforced pipe is polypropylene, the good pipe has no smell, the bad pipe has strange smell, it is likely to be mixed with polyethylene, not polypropylene;
第四,“捏”硬度。
Fourth, "pinch" hardness.
双扣聚氯乙烯增强管具有相当的硬度,随随便便可以捏变形的管,肯定不是PP-R管;
The double button PVC reinforced pipe has a considerable hardness, which can be easily pinched and deformed. It is certainly not PP-R pipe;
第五,“量”壁厚,
Fifth, measure the wall thickness,
另外可以用游标卡尺测量,管壁厚是否达标且均匀,一般好管都是严格按国标生产,但这种方法要求对双扣聚氯乙烯增强管国家标准有一定了解。
In addition, vernier caliper can be used to measure whether the pipe wall thickness is up to standard and uniform. Generally, good pipes are produced strictly according to the national standard, but this method requires a certain understanding of the national standard for double button PVC reinforced pipes.
