                如何辨別PP-R管材性能好壞那六个九级仙帝大吼道!

                作者: admin    來源:http://www.laobingguandao.com  時間:2019-08-26    人氣:
                  第一,“看”外觀。
                  First, look at the appearance.
                  顏色,好的PP-R水管色澤柔和均勻一致,無雜色。(PP-R管主要有白灰綠黃幾種,消費者往往認為白色才是最好的,其實顏色並非判斷質量好壞的標準, 實際上PP-R水管的好壞跟PP-R水管的顏色沒有任何關系。塑料哈哈狂笑道粒子以白色、透明色(也有已再走一步加好色母其他顏色)為主只要加上色母什麽顏色都可以生產,色母不會被分解也不會改變PP-R品質,因此單就水管而言什麽顏色也沒有關系,按國家規定PP-R水管要有良好的閉〗光性能,就這點而言灰色笑吟吟开口或其他不透光性能的去 读 读 會好一些。但是這樣的優勢灵魂力量僅在明管安裝和管道井內存在,家裝的水管全部是暗埋的,所以就根本不存在著灰色要優於其他顏色之說。PP-R管完全不透光,偽PP-R管輕微透光或半透光。白色產品没想到你一般只能用純PP-R原料產生,如加回收料、廢料、角料生產□出來的產品其色澤不柔和也不均勻,而嗤用色母加工的其他顏色產品添加回收料、廢料、角料等就不會影響產品色∮澤。這就是為什麽註重品質的以家裝零售為主的不少廠家產品都以白色為主 );
                  Color, good PP-R pipe color is soft and uniform, without any color. (PP-R pipes are mainly white, grey, green and yellow. Consumers often think that white is the best. In fact, color is not the criterion to judge the quality of PP-R pipes. In fact, the quality of PP-R pipes has nothing to do with the color of PP-R pipes. Plastic particles are mainly white and transparent (and other colors have been added to the masterbatch) as long as any color can be produced, the masterbatch will not be decomposed and will not change the quality of PP-R. Therefore, it does not matter what color the water pipe is. According to the national regulations, PP-R water pipe should have good light-closing performance, in this regard, the masterbatch will not be decomposed and will not change the quality of PP-R. Grey or other opaque properties will be better. But this advantage only exists in open pipe installation and pipeline wells, and all domestic pipes are buried, so there is no saying that gray is superior to other colors at all. PP-R tube is completely opaque, and pseudo-PP-R tube is slightly or semi-transparent. White products can only be produced with pure PP-R raw materials. For example, the products produced with recycled materials, waste materials and corners have soft and uneven color. Adding recycled materials, waste materials and corners to other color products processed with masterbatches will not affect the color of products. This is why many of the home decoration retail products that focus on quality are mainly white.

                  產品內外表面應光滑平整,不允許有身上氣泡、明顯的凹陷、溝槽和雜質等缺陷。
                  The inner and outer surface of the product should be smooth and smooth, and no defects such as bubbles, obvious depressions, grooves and impurities should be allowed.
                  第二,“摸”質地。
                  Second, "touch" texture.
                  好的PP-R水管100%是PP-R原料(無任何添加料)質地純正,表面光潔,手感柔和,偽PP-R管手感光滑,一般來說,顆粒粗糙的很可能摻和了雜質;
                  Good PP-R pipes are 100% pure PP-R raw materials (without any additives), smooth surface, soft handle, and smooth handle of pseudo-PP-R pipes. Generally speaking, rough particles are likely to be mixed with impurities.
                  第三,“聞”氣味。
                  Third, smell.
                  PP-R管主要材料是聚丙烯,好的管材沒有氣味,差的則有怪出现在星际传送阵之前味,很可能是摻和了聚乙而实际上烯,而非聚力量丙烯;
                  The main material of PP-R pipe is polypropylene, good pipe has no odor, bad pipe has strange odor, probably mixed with polyethylene, not polypropylene;
                  第四,“捏”硬度。
                  Fourth, "pinch" hardness.
                  PP-R管具有相當的硬度,隨隨便便可以捏變形的管,肯定不是PP-R管;
                  PP-R pipe has considerable hardness and can be pinched easily. It is definitely not a PP-R pipe.
                  第五,“量”壁厚,
                  Fifth, "measure" wall thickness.
                  另外可以用遊標卡尺測量,管壁厚是否達標且均勻,一般好管都是嚴格按國標生產,但這種方法要求對☆PP-R管國家標準有一定了解。
                  In addition, vernier calipers can be used to measure whether the pipe wall thickness is up to the standard and uniform. Generally, good pipe is produced strictly according to the national standard, but this method requires a certain understanding of the national standard of PP-R pipe.
                  第六,“聽”聲音
                  Sixth, "Listen" to the voice

                  PPR Pipe, PPR, PPR Pipe Properties
