Papa polipropylene PP K8003

PP waiwai kino: non-toxic, odorless, tasteless, milky white, high crystalline polymer with a relative molecular weight of about 80000-150000.ʻO ka liʻiliʻi liʻiliʻi: 0.89-0.91g / cm3, ʻo ia kekahi o nā ʻano māmā loa i nā plastics.ʻO ka hydrophobicity ikaika: ʻo ka nui o ka lawe ʻana i ka wai i ka wai no 24h he 0.01% wale nō.Maikaʻi ke ʻano.

Mechanical waiwai PP he kiʻekiʻe crystallinity a me ka hana maʻamau, no laila, he maikai loa mechanical waiwai.ʻO ka hana maikaʻi loa ʻo ke kūlou ʻana i ka luhi.

He pale wela maikaʻi ka PP.Hiki ke sterilized ka huahana ma kahi mahana ma luna o 100 ° C. ma lalo o ke ʻano o ka ikaika o waho, ʻaʻole ia e deform ma 150 ° C. ʻO ka mahana embrittlement - 35 ℃.ʻO ka hoʻonui ʻana o ka isotacticity a i ʻole ka emi ʻana o ke kaumaha molekala he mea maikaʻi ia i ka hoʻomaikaʻi ʻana i nā waiwai wela.

Paʻa kemika: maikaʻi loa ka paʻa kemika o PP.Hiki ke hoʻopau ʻia e ka ʻakika sulfuric concentrated a me ka waikawa nitric concentrated, a ʻano paʻa i nā reagents kemika ʻē aʻe;Eia nō naʻe, hiki i ka haʻahaʻa molecular haʻahaʻa aliphatic hydrocarbons, aromatic hydrocarbons a me ka chlorinated hydrocarbons hiki ke palupalu a pehu ka polypropylene, a ua hoʻomaikaʻi ʻia kona kūpaʻa kemika me ka piʻi ʻana o ka crystallinity.

Wahi a ka hana i luna, kūpono ʻo PP no nā huahana aʻe:

1. Injection: valve, mea pono, crates, automotive, closure, appliances, kettles, food containers, housewares, toys, non-prefilled syringe.
2. Extrusion: pepa mānoanoa, pepa, paipu, mauʻu, strapping, pepa palapala, BOPP Film, pepa lahilahi, band.Puhi Puhi: ʻōmole.
3. Thermoforming: pā, kīʻaha, kīʻaha jelly, kīʻaha wai.
4. ʻO ka ʻeke palahalaha: ʻeke ulana, ʻeke jumbo, ʻeke.
5. Fiber: multifilament, kāpeti, Spundbond, non-wovens.
6. Kiʻiʻoniʻoni: Kiʻiʻoniʻoni (CPP), Kiʻiʻoniʻoni puhi (IPP).
