PVC isanapangidwe kuti ipangidwe, iyenera kuphatikizidwa ndi zowonjezera zosiyanasiyana zapadera. Izi zowonjezera zitha kukopa kapena kudziwa zingapo za zinthu zomwe zimapangidwa, zomwezo; Mphamvu zake, nyengo ya ukali, mtundu wake ndi kumveka bwino komanso momveka ngati zikugwiritsidwa ntchito polemba. Njirayi imatchedwa kuphatikiza. Kugwirizana kwa PVC ndi mitundu yambiri yamitundu yambiri ndi imodzi mwazinthu zomwe mphamvu zambiri zimakhala ndi mphamvu zambiri ndipo ndizomwe zimapangitsa kuti ikhale poilymer yosiyanasiyana. PVC imatha kukhala yopukutidwa kuti ipange kusinthasintha kuti igwiritse ntchito pansi ndi zinthu zamankhwala. Rigid PVC, yomwe imadziwikanso kuti PVC-U (Umayima "osagwiritsidwa ntchito" amagwiritsidwa ntchito kwambiri popanga mafelemu a pawindo.

Zowonjezera zomwe zimagwiritsidwa ntchito mu zida zonse za PVC zimaphatikizira zolimbitsa thupi, mafuta, komanso ma pvc osinthika, mafilimu. Zowonjezera zosankha, zimaphatikizapo zinthu zingapo kuchokera ku Edzi, zosintha zamagetsi, ma firmant okhazikika, mafilimu, mapangidwe am'madzi, ndikuwombera mapulogalamu ena. Ma pvc enieni a pvc polymer omwe ali pansi pa malo ena amakhala otsika kwambiri mpaka 25% pogwiritsa ntchito misa, omwe amatsalira amawerengera zowonjezera. Kugwirizana kwake ndi zowonjezera kumalola kuwonjezera moto wovuta ngakhale pvc ndi boot molt mota chifukwa cha kupezeka kwa chlorine ku Polymer Matrix.

Kutentha

Kukhazikitsa zolimbitsa thupi ndikofunikira pakupanga kwa PVC kuti muchepetse kuwonongeka kwa PVC ndi kutentha ndi kukameta ubweya. Amathanso kukulitsa kukana kwa pvc masana, ndikuchita nyengo komanso kutentha. Kuphatikiza kwa omaliza kutentha kumakhala ndi kofunikira pazinthu zakuthupi za PVC ndi mtengo wa mawonekedwe. Kusankha kutentha kwa kutentha kumadalira zinthu zingapo kuphatikizapo zomwe zimagwiritsidwa ntchito ndi maluso a PVC, zofunika kuvomerezedwa ndi mtengo.

MafutaIzi zimagwiritsidwa ntchito kuchepetsa mikangano pokonzekera. Mafuta akunja amatha kuchepetsa mikangano pakati pa pvc ndi zida zokuthandizani, mafuta opaka mafuta amagwira ntchito pa ma granules a PVC.

MabulosiPhukusi la pulasitiki ndi chinthu chomwe chimawonjezeredwa ku zinthu, nthawi zambiri pulasitiki, zimapangitsa kuti zizitha kusintha, zotsalira komanso zosavuta kuthana nazo. Zitsanzo zoyambirira za ma pulasitiki zimaphatikizapo madzi kuti afewe dongo ndi mafuta kuti asungunuke maboti oyenda m'madzi akale. Kusankhidwa kwa mavidiyi kumadalira zinthu zomaliza zomwe zimafunikira popanga zomaliza, ndipo moyenera ngati mankhwalawo ali ndi ntchito yopanga pansi kapena ntchito yachipatala. Pali mitundu yoposa 300 ya maguputala yomwe pafupifupi 50-100 ikugwiritsa ntchito malonda. Mapulasi ambiri omwe amagwiritsidwa ntchito kwambiri ndi Phtates omwe amatha kugawidwa m'magulu awiri osiyana ndi mapulogalamu osiyanasiyana kwambiri. Kuchepetsa pang'ono: Kulemera kochepa kwa mafinya (LMW) Phthalate ndi ma atomu a kaboni asanu ndi atatu kapena ocheperako m'matumbo anga. Izi zikuphatikiza, DHP, DBP, DBP ndi BBP. Kugwiritsa ntchito Phtates ku Europe kumangogwiritsa ntchito mapulogalamu enaake. Mkulu wa Phtates: Kulemera kwambiri kwa mafinya (hmw) Phthalate Izi zikuphatikiza: DINP, Dop, DFP, DIUP ndi DTDP. HMW Phthalate imagwiritsidwa ntchito mosamala nthawi zonse kuphatikiza zingwe ndi pansi. Mapulasitiki, monga opitira, a Cirrate, Benzonte komanso ma trimli azoloweredwa pomwe pali zinthu zapadera zomwe zimatha kupirira kutentha kochepa kapena komwe kusinthasintha ndikofunikira. Zinthu zambiri za PVC zomwe timagwiritsa ntchito tsiku ndi tsiku koma zimangotengera ma pulasitiki a PHkha. Zimaphatikizapo chilichonse kuchokera ku zida zopulumutsa moyo monga machubu azachipatala ndi matumba amwazi, kutsekeka, zingwe zamagetsi, zotchinga, ndi zoseweretsa, ndi zoseweretsa. Kuphatikiza apo, Phtates amagwiritsidwa ntchito popanga mapulogalamu ena opezeka PVC monga zojambula, zinthu za mphira, zomatira ndi zodzoladzola.
