聚氯乙烯胶泥的熬制
那么这两者的区别又在哪里呢?首先,他们首先在使用上有很大不同,聚氯乙烯一般是袋装的,形态为黑色固体状,使用前需要用铁锅熬制,待胶泥软化后才可以使用。而沥青胶泥一般为桶装,与聚氯乙烯胶泥一样一桶为25公斤,其状态为液体状或者为糊状(沥青胶泥分非下垂和自流平,非下垂为糊状,自流平为液体状),其开桶就可以立即使用。
So what's the difference between the two? First of all, they are very different in use. PVC is usually bagged in black solid form. Before use, it needs to be boiled in an iron pot and can be used only after the cement is softened. The asphalt mastic is generally in barrels, and 25 kg is the same as PVC mastic. Its state is liquid or paste (asphalt mastic is divided into non sagging and self leveling, non sagging is paste, self leveling is liquid), and it can be used immediately after opening the barrel.
其次,两者在施工后的表现也有些许的差异,聚氯乙烯胶泥可以保证在夏季70摄氏度不流淌,冬季零下25摄氏度不开裂,且粘结性非常优良,但是沥青胶泥的表现就要稍微差些,冬季易起皮,夏季易流淌,长久表现来看比聚氯乙烯胶泥要差一些。
Secondly, there are some differences between the performance of the two after construction. PVC mastic can ensure that it does not flow at 70 ℃ in summer, does not crack at - 25 ℃ in winter, and has excellent cohesiveness. However, the performance of asphalt mastic is slightly worse. It is easy to peel in winter and flow in summer, which is worse than PVC mastic in the long run.
