Ndeupi musiyano uripo pakati pe pom purasitiki uye pepurasitiki

Tsanangudzo yePOM (Polyoxymymelene Resin): PolyoxyMexyMely in the linear Polymer pasina maketani, yakakwirira density uye yakakwirira crystallinity. Maererano nechimiro chakasiyana chemakemikari mumatanda emalocular, chinogona kukamurwa kuita marudzi maviri: homopolyoxyoxymymelene uye copolyoxymycelene. Musiyano wakakosha pakati pezviviri zviri: Homopolyoxyoxymelene ane density yakanyanya, uye yekunyungudika, asi yakatetepa yekudzikisira tembiricha (anenge gumi ℃), uye zvishoma kugadzikana kugadzikana kuAcid naAlkali; Nepo Coplyyoxymymelene ane density yakanyanya, crystallinity, uye iyo yekunyungudika uye simba rakanyanyisa kunaka, iyo yekudzora tembiricha yakakura (anenge 50 ℃), uye kugadzikana kuAcid naAlkali zvakanaka. Iyo ipurasitiki yeinjiniya ine zvakanakisa zvizere zvinhu. Iyo ine yakanaka yemuviri, michina uye yemakemikari zvivakwa, kunyanya kupokana kwakanaka. Inowanzozivikanwa seSaigang kana duogang, ndiyo yechitatu yakakura kwazvo-ine chinangwa mapurasitiki. Izvo zvakakodzera kuita kuti uwedzere-kuderedza uye kupfeka zvikamu zvekudzivirira, zvikamu zvekutapurirana, uye makemikari, chiridzwa uye zvimwe zvikamu.
Pe (polyethylene inotaurwa sepen)

Polyethylene (pe kwenguva pfupi) iri thermoplastic resin yakagadzirwa nePolymerizing Ethylene. Mune indasitiri, inosanganisirawo vaCopolyer uye huwandu hushoma hwe α-olefins. Polyethlene kusanzwisisika, kusiri-chepfu, kunonzwa kunge wax, kune yakanakisa kupisa kupisa, kudzikisira kwemakemikari akanaka, uye kunogona kutsungirira acids zvakanyanya uye alkalis. Izvo zvisinganyanzvi mune general sol sol sol sol sol Zvivakwa zvePolysetylene zvakajairika, simba rakaderera rakaderera, kuramba kukanganisika hakuna kunaka, uye kuramba kukanganisika kwakanaka. Polyethlene anogona kuongororwa nekurova kuumbwa, kuendesa, jekiseni kuumbwa uye dzimwe nzira, uye rinoshandiswa zvakanyanya mukugadzira mafirimu, zvigadzirwa zvemagetsi, machira uye zuva nezuva sundors.
