Is PVC Thermoplastic?
PVC (polyvinyl chloride) chinhu che thermoplastic.
Thermoplastics imhando yepolymer inogona kunyungudutswa uye kuumbwazve kakawanda pasina kuita shanduko yakakosha yemakemikari. PVC ndiwo thermoplastic polymer iyo inoshandiswa zvakanyanya mumashandisirwo akasiyana siyana nekuda kweiyo yakasarudzika midziyo yakadai sekugara, kuchinjika, uye kuramba kumakemikari uye mamiriro ekunze.
PVC inogadzirwa ne polymerizing vinyl chloride monomer (VCM) kuburikidza nenzira inonzi suspension polymerization. Iyo inokonzeresa polymer ihupfu chena inogona kugadziriswa kuita akasiyana siyana senge pombi, mashiti, mafirimu, uye profiles.
Imwe yemabhenefiti akakosha e PVC sechinhu che thermoplastic kugona kwayo kugadziriswa nyore nyore kuburikidza nehunyanzvi hwakasiyana senge extrusion, jekiseni kuumba, uye kuvhuvhuta. Izvi zvinoita kuti ive sarudzo yakakurumbira kune dzakasiyana siyana dzekushandisa senge kuvaka, mota, kurongedza, uye zvigadzirwa zvekurapa.
Pamusoro peiyo thermoplastic properties, PVC inewo humwe hunhu hwakasiyana hunoita kuti ibude kubva kune mamwe thermoplastics. Semuyenzaniso, PVC iri inherent flame retardant, izvo zvinoita kuti ive sarudzo yakakurumbira yezvikumbiro uko kuchengetedza moto kuri kunetseka. PVC inopesanawo nemwaranzi yeUV, inoita kuti ive yakakodzera kushandiswa kwekunze.
Zvisinei, zvakakosha kuziva kuti PVC zvakare ine zvimwe zvinonetsa kwezvakatipoteredza zvine chekuita nekugadzirwa kwayo uye kuraswa. Kugadzirwa kwe PVC inosanganisira kushandiswa kwemakemikari ane chepfu seVCM, ayo anogona kukanganisa hutano hwevanhu uye nharaunda. Uyezve, PVC haisi biodegradable uye inogona kuramba iri munzvimbo kwenguva yakareba mushure mekuraswa.
Mukupedzisa, PVC chinhu chinonzi thermoplastic chinoshandiswa zvakanyanya mumashandisirwo akasiyana siyana nekuda kwezvakasiyana zvimiro zvakaita sekugara, kuchinjika, uye kuramba makemikari uye mamiriro ekunze. Kunyangwe iine zvimwe zvinonetsa kwezvakatipoteredza zvine chekuita nekugadzirwa kwayo uye kuraswa, inoramba iri sarudzo yakakurumbira kune akawanda maindasitiri nekuda kwekuita kwayo uye nyore kugadzirisa.
Mhoro apo, ndangotanga kungwarira bhurogi rako kuburikidza neGoogle, uye wakaona kuti rine ruzivo rwechokwadi. Ini ndichatarisa mabrussels. Ndichatenda kana mukaenderera mberi neizvi mune ramangwana. Vanhu vazhinji vachabatsirwa nekunyora kwako. Mufaro!
