(ningbo) Taiwan Formosa Plastics pp5090t babban amfani:
PP wani abu ne na Semi crystalline.Yana da wuya fiye da PE kuma yana da matsayi mafi girma.Tunda nau'in homopolymer PP yana da ƙarfi sosai lokacin da zafin jiki ya ƙasa da 0 ℃, yawancin kayan kasuwanci na PP sune copolymers bazuwar tare da 1-4% ethylene ko nau'in nau'in nau'in copolymers tare da abun ciki na ethylene mafi girma.Nau'in nau'in copolymer PP abu yana da ƙananan zafin jiki na murdiya (100 ℃), ƙarancin gaskiya, ƙarancin sheki da ƙarancin ƙarfi, amma yana da ƙarfin tasiri mai ƙarfi.
Matsakaicin adadin MFR na PP ya fito daga 1 zuwa 40. PP tare da ƙananan MFR yana da tasiri mafi tasiri amma ƙananan ƙarfin ƙarfi.Don kayan da ke da MFR iri ɗaya, ƙarfin nau'in copolymer ya fi na nau'in homopolymer.Saboda crystallization, da shrinkage kudi na PP ne quite high, kullum 1.8-2.5%.Kuma daidaituwar shugabanci na shrinkage ya fi na PE-HD da sauran kayan.Ƙara 30% ƙari gilashin zai iya rage raguwa zuwa 0.7%.
Nau'in Homopolymer da nau'in copolymer PP kayan suna da kyakkyawan juriya na sha danshi, juriyar lalata tushen acid da juriya na rushewa.Duk da haka, ba ta da juriya ga ƙamshi na hydrocarbon (kamar benzene) da sauran ƙarfi na chlorinated hydrocarbon (carbon tetrachloride).PP ba shi da juriya na iskar shaka a babban zafin jiki kamar yadda PE ke yi.
Dangane da aikin da ke sama, PP ya dace da samfuran masu zuwa:
1. allura: bawuloli, na'urorin haɗi, akwatuna, motoci, rufewa, kayan lantarki, kwalabe na ruwa, kwantena abinci, kayan gida, kayan wasan yara, sirinji marasa cikawa.
2. Extrusion: m takardar, takardar, bututu, bambaro, dauri tef, stationery sheet, BOPP film Sheet da tsiri.
3. Busa gyare-gyare: kwalban.
4. Thermoforming: tire, kwano, jelly kofin, ruwa kofin.
5. Flat yarn: jakar da aka saka, jakar akwati, kafet.
