PVC guduro samu daga polymerization ne musamman m saboda da low thermal kwanciyar hankali & high narke danko.Yana buƙatar gyara kafin sarrafawa zuwa samfuran da aka gama.Ana iya haɓaka abubuwan da ke cikinta ta hanyar ƙara abubuwan da suka haɗa da ƙari da yawa, kamar masu daidaita zafi, masu daidaita UV, masu yin filastik, masu gyara tasiri, masu cikawa, masu ɗaukar wuta, pigments, da sauransu.
Zaɓin waɗannan abubuwan ƙari don haɓaka kaddarorin polymer ya dogara da ƙarshen buƙatar aikace-aikacen.Misali:
1.Plasticizers (Phthalates, Adipates, Trimellitate, da dai sauransu) ana amfani da su azaman softening jamiái don bunkasa rheological da inji yi (tauri, ƙarfi) na vinyl kayayyakin da kiwon da zazzabi.Abubuwan da ke shafar zaɓin masu yin filastik don vinyl polymer sune: dacewa da polymer; ƙarancin ƙarfi, farashi.
2.PVC yana da ƙarancin kwanciyar hankali na thermal kuma masu daidaitawa suna taimakawa hana lalata polymer yayin aiki ko ɗaukar haske.Lokacin da aka yi zafi, mahadi na vinyl suna fara haɓaka haɓakawar dehydrochlorination kuma waɗannan masu daidaitawa suna kawar da HCl da aka samar suna haɓaka rayuwar polymer.Abubuwan da za a yi la'akari yayin zabar masu daidaita zafi sune: buƙatun fasaha; Amincewa da tsari; farashi.
3.Fillers suna ƙarawa a cikin mahaɗan PVC don dalilai daban-daban.A yau, mai filler zai iya zama ƙari na aikin gaskiya ta hanyar sadar da ƙima a cikin sabbin hanyoyi masu ban sha'awa a mafi ƙarancin yuwuwar ƙira.Suna taimakawa: ƙara ƙarfi da ƙarfi, haɓaka aikin tasiri, ƙara launi, rashin ƙarfi da haɓakawa da ƙari.
Calcium carbonate, titanium dioxide, calcined lãka, gilashin, talc da dai sauransu su ne na kowa iri fillers amfani a PVC.
4.External man shafawa ana amfani da su taimaka m nassi na PVC narke ta wurin aiki kayan aiki.yayin da man shafawa na ciki yana rage danko narke, hana zafi da kuma tabbatar da launi mai kyau na samfurin.
5.Other Additives kamar aiki aids, tasiri modifiers, an kara da cewa inganta inji kazalika da surface Properties na PVC.
