PVC ndeimwe yemapurasitiki anonyanya kushandiswa muindasitiri. Plasticol, kambani yekuItaly iri pedyo neVarese yave ichigadzira magranule ePVC kwemakore anopfuura makumi mashanu ikozvino uye ruzivo rwakawanikwa mumakore apfuura rwakabvumira bhizinesi kuwana hunyanzvi hwakadzama zvekuti ikozvino tinogona kuishandisa kugutsa zvikumbiro zvevatengi vese vachipa zvigadzirwa zvitsva uye zvakavimbika.
Chokwadi chekuti PVC inoshandiswa zvakanyanya pakugadzira zvinhu zvakasiyana-siyana chinoratidza kuti hunhu hwayo hwemukati hunobatsira zvikuru uye hunokosha. Ngatitangei kutaura nezvekuomarara kwePVC: chinhu chacho chakaoma zvikuru kana chakachena asi chinochinjika kana chikasanganiswa nezvimwe zvinhu. Hunhu uhwu hwakasiyana hunoita kuti PVC ikwane pakugadzira zvigadzirwa zvinoshandiswa muminda yakasiyana, kubva pakuvaka kusvika kumotokari.
Zvisinei, hazvisi zvese zviri nyore kushandisa. Kupisa kwekunyunguduka kwepolymer iyi kwakaderera, izvo zvinoita kuti PVC isakodzere nzvimbo dzinopisa zvakanyanya.
Uyezve, njodzi dzinogona kubva pakuti, kana ikapisa zvakanyanya, PVC inoburitsa mamorekuru echlorine sehydrochloric acid kana dioxin. Kusangana nechinhu ichi kunogona kukonzera matambudziko ehutano asingagadzirisiki.
Kuti polymer ienderane nekugadzirwa kwayo mumaindasitiri, inosanganiswa nezvinodzivirira, mapurasitiki, mavara, uye mafuta anobatsira mukugadzirwa pamwe nekuita kuti PVC ive nyore kupfava uye isanyanya kusakara.
Zvichienderana nehunhu hwayo uye njodzi yayo, magranule ePVC anofanirwa kugadzirwa mumiti yakasarudzika. Plasticol ine mutsetse wekugadzira wakatsaurirwa chete kupurasitiki iyi.
Danho rekutanga rekugadzira ma granules ePVC rinosanganisira kugadzirwa kwemachubhu marefu echinhu chakagadzirwa kuburikidza nechinhu chakakosha che extrusion plant. Danho rinotevera rinosanganisira kucheka mapurasitiki kuita mabhora madiki chaizvo. Maitiro acho ari nyore chaizvo, asi zvakakosha zvikuru kushandisa kungwarira pakubata chinhu chacho, uchitora matanho ekutanga anogona kuita kuti chiome zvakanyanya.
