PPH is a kind of homopolymer polypropylene with high molecular weight and low melting finger. The material has been modified by β to have uniform and fine Beta crystal structure, which makes it not only have excellent chemical resistance, high temperature resistance and good creep resistance, but also have excellent impact resistance at low temperature.
E like me nā hiʻohiʻona o nā mea PPH, ua hana ʻia ka pā PPH i nā mea kūʻai corrosion i hoʻohana nui ʻia i ka ʻili kemika, metallurgy a me nā mea uila a me nā māla ʻē aʻe. PPH pickling tank a electrolytic tank, ʻoi aku ka waiwai a me ka lōʻihi, e hōʻemi i ka mālama ʻana i nā mea hana, a hoʻonui i ke ola lawelawe, me ka hana ʻoi aku ka maikaʻi.
