Chii chinonzi Modified Polyethylene?
Mhando dzakagadziridzwa dze polyethylene dzinonyanya kusanganisira chlorinated polyethylene, chlorosulfonated polyethylene, cross-yakabatana polyethylene uye akasanganiswa akagadziridzwa marudzi.
Chlorinated Polyethylene:
A random chloride inowanikwa nekutsiva zvishoma maatomu ehydrogen mu polyethylene neklorini. Chlorination inoitwa pasi pekutanga kwechiedza kana peroxide, uye inonyanya kugadzirwa neaqueous suspension method muindasitiri. Nekuda kwekusiyana kwehuremu hwemamorekuru uye kugovera, dhigirii rebazi, chlorination degree mushure meklorini, chlorine atomu kugovera uye yakasara crystallinity yembishi polyethylene, chlorinated polyethylene kubva rubbery kune yakaoma plastiki inogona kuwanikwa. Iko kushandiswa kukuru kwaita semugadziriso wepolyvinyl chloride yekuvandudza kukanganiswa kwepolyvinyl chloride. Chlorinated polyethylene pachayo inogonawo kushandiswa semagetsi insulating zvinhu uye pasi zvinhu.
Chlorosulfonated polyethylene:
Kana polyethylene ikasangana ne chlorine ine sulfur dioxide, chikamu chemaatomu ehydrogen mumorekuru chinotsiviwa neklorini uye zvishoma zve sulfonyl chloride mapoka kuti awane chlorosulfonated polyethylene. Nzira huru yeindasitiri ndiyo nzira yekumisa. Chlorosulfonated polyethylene inoshingirira kune ozone, makemikari corrosion, mafuta, kupisa, chiedza, abrasion uye tensile simba. Iyo elastomer ine yakanaka yakazara zvivakwa uye inogona kushandiswa kugadzira midziyo yemidziyo inobata chikafu.
XLPE:
Kushandisa nzira yemwaranzi (X-ray, electron beam kana ultraviolet irradiation, zvichingodaro) kana nzira yemakemikari (peroxide kana silicone cross-linking) kugadzira linear polyethylene kuita network kana yakawanda-yakabatana polyethylene. Pakati pavo, iyo silicone cross-linking nzira ine maitiro akareruka, yakaderera mari yekushandisa, uye kuumba uye kuchinjika-kubatanidza kunogona kuitwa mumatanho, saka kuvhuvhuta kuumba uye jekiseni kuumba kwakakodzera. Kupisa kwekudzivirira, kwezvakatipoteredza kusagadzikana kuputsa kuramba uye mechanical properties ye cross-linked polyethylene inovandudzwa zvikuru kana ichienzaniswa ne polyethylene, uye inokodzera pombi hombe, tambo uye waya, uye rotomolding zvigadzirwa.
Kusanganiswa kwekugadzirisa polyethylene:
Mushure mekubatanidza mutsara wakaderera density polyethylene uye yakaderera density polyethylene, inogona kushandiswa kugadzira mafirimu nezvimwe zvigadzirwa, uye kuita kwechigadzirwa kuri nani pane yakaderera density polyethylene. Polyethylene uye ethylene propylene rubber inogona kusanganiswa kuti ibudise zvakasiyana-siyana. thermoplastic elastomers
