PVC plastiki inoreva musanganiswa wePVC muindasitiri yemakemikari.Chirungu Zita: polyvinyl chloride, Chirungu chidimbu: PVC.Ichi ndicho chinonyanya kushandiswa chirevo chePVC.
Ruvara rwayo rwechisikigo rwakaita yellowish translucent uye kupenya.Kujeka kuri nani pane iyo polyethylene uye polypropylene, uye yakaipisisa kupfuura iyo yepolystyrene.Zvichienderana nehuwandu hwekuwedzera, inogona kukamurwa kuita nyoro uye yakaoma PVC.Zvigadzirwa zvakapfava zvakapfava uye zvakaoma, uye zvinonzwa zvakanamira.Kuoma kwezvigadzirwa zvakaoma zvakakwirira kudarika zvepasi-density polyethylene, asi yakaderera pane iyo polypropylene, uye pachava nealbinism pamabhendi.Zvigadzirwa zvakajairika: mahwendefa, mapaipi, soles, matoyi, magonhi nemahwindo, matehwe waya, stationery, etc. Imhando yemhando yepolymer zvinhu zvinoshandisa atomu yechlorine kutsiva atomu yehydrogen mu polyethylene.
Mumhanyi uye gedhi: ese akajairwa magedhi anogona kushandiswa.Kana uchigadzirisa zvikamu zviduku, zvakanakisisa kushandisa gedhi remhando yetsono kana gedhi rakanyura;Kune zvikamu zvakakora, zviri nani kushandisa magedhi akafanana nefani.Hudiki dhayamita yegedhi rerudzi rwetsono kana gedhi rakanyura richava 1mm;Ukobvu hwegedhi rakaita se fan hahufanire kuve pasi pe1mm.
Mashandisiro akajairika: pombi dzemvura, pombi dzemumba, madziro emba, mabhomba emuchina webhizinesi, kurongedza zvigadzirwa zvemagetsi, zvishandiso zvekurapa, kurongedza chikafu, nezvimwe.
Kemikari uye yemuviri zvimiro zvePVC yakaoma PVC ndeimwe yeanonyanya kushandiswa epurasitiki zvinhu.PVC zvinhu ndeye amorphous zvinhu.Stabilizers, lubricant, anobatsira ekugadziridza maajenti, pigment, reinforcing agents uye zvimwe zvinowedzera zvinowanzowedzerwa kune PVC zvinhu mukushandisa kunoshanda.
PVC zvinhu hazvina kupisa, simba rakakwirira, kuramba mamiriro ekunze uye yakanakisa geometric kugadzikana.PVC ine kuramba yakasimba kune oxidants, reductants uye yakasimba asidhi.Nekudaro, inogona kusvibiswa neyakaomeswa oxidizing asidhi yakadai seyakaomeswa sulfuric acid uye yakadzika nitric acid, uye haina kukodzera nguva dzekusangana neanonhuhwirira hydrocarbons uye chlorinated hydrocarbons.
Iyo yekunyunguduka tembiricha yePVC panguva yekugadziriswa ndiyo yakakosha maitiro parameter.Kana iyi parameter isina kukodzera, inotungamira kune dambudziko rekuparara kwezvinhu.Mamiriro ekuyerera ePVC akashata, uye maitiro ayo akasiyana akatetepa.Kunyanya, zvinhu zvePVC zvine huremu hombe hwemamorekuru zvinonyanya kunetsa kugadzirisa (ichi chinhu chinowanzoda kuwedzera lubricant kuti uvandudze kuyerera maitiro), saka PVC zvinhu zvine huremu hudiki hwemamorekuru zvinowanzo shandiswa.Iyo shrinkage yePVC yakanyanya kuderera, kazhinji 0.2 ~ 0.6%.
