Pamberi PVC inogona kuitwa mune zvigadzirwa, inofanira kusanganiswa pamwe nehuwandu hwehuwandu hwekuwedzera. Aya maodzwa anogona kupesvedzera kana kuona huwandu hwezvigadzirwa zvivakwa, kureva; Zvivakwa zvaro zvemakanika, kutsanya kwemamiriro ekunze, ruvara rwayo uye kujekesa uye zvechokwadi kuti zvinofanirwa kushandiswa muchirongwa chinoshanduka. Kuita uku kunodaidzwa kujekesa. Pvc's kuenderana nemhando dzakawanda dzakasiyana dzekuzvidzwa ndeimwe yemidziyo yakawanda uye ndiyo inoita kuti ive iyo yakanyanya kuita polymer. PVC inogona kupurasitiki kuti iite inoshanduka kuti ishandiswe muzvishandiso uye zvekurapa zvigadzirwa. Rigid PVC, inozivikanwawo sePVC-U (iyo iwe unomiririra "isina kurongwa") inoshandiswa zvakanyanya mukuvaka maficha akadai sewindows.

MaDriveal anowedzera anoshandiswa mune zvese zvigadzirwa zvePVC zvinosanganisira kupisa stabilizers, lubriants, uye mune iyo inochinja pvc, plasticisers. Offices Officives, sanganisira huwandu hwezvinhu kubva pakugadzirisa AIDS, zvinokanganisa modifiers, aiv stabilizers, murazvo unodzora, pigments, kune vamiriri, uye kuridza vamiririri vezvinyorwa zvakati. Iyo chaiyo PVC Polymer zvemukati mune zvimwe zvekushandiswa pasi zvinogona kuve zvakaderera se25% neMarasi, iyo yakasara yakaverengerwa nevanowedzera. Kuenderana kwayo nekuwedzera kunobvumira kuwedzera kwekuwedzera kwemurazvo unodzoreredza kunyangwe PVC iri mumoto wekudzosera moto wekusimbisa kweChrorine muPolymer Matrix.

Inoshanda yekuwedzera

Kupisa stabilizer

Kupisa kupisa kunodiwa mune ese maPVC mafambiro ekudzivirira kuora kwePVC nekupisa uye neshear panguva yekugadzirisa. Ivo vanogona zvakare kusimudzira kuramba kwaPVC kusimuka kwemasikati, uye pakumisa uye kupisa kuchembera. Mukuwedzera kupisa maStabilizers vane kukosha kwakakosha pazvinhu zvepanyama zvePVC uye mutengo weiyo fomu. Sarudzo yeHot Stabilizer inoenderana nezvinoverengeka zvinhu zvinosanganisira izvo zvehunyanzvi zvinodiwa zvePVC chigadzirwa, chinodzora mvumo inobvumirwa uye mutengo.

LubriantsIzvi zvinoshandiswa kuderedza kupokana panguva yekugadzirisa. Kunze kweLubricants kunogona kuderedza kupokana pakati pePVC uye zvigadzirwa zvekugadzirisa, nepo maLubricants emukati anoshanda paPVC Granules.

PlasticisersPlasticiser chinhu icho chinowedzerwa kune chimwe chinhu, kazhinji papurasitiki, inoita kuti ive inoshanduka, yakabatikana uye nyore kubata. Mienzaniso yekutanga yePlasticisers inosanganisira mvura kuti inyore ivhu nemafuta kuti apfekere purasikiro yekuchengetedza mvura yekare. Iko kusarudzwa kwePlasticisers kunoenderana nezvinhu zvekupedzisira zvinodikanwa neyekupedzisira chigadzirwa, uye zvechokwadi kuti chigadzirwa chiri chekushandisa pasi kana chekurapa application. Kune anopfuura mazana matatu emhando dzakasiyana dzemhando dzeplasticisers dzadzo dzinenge 50-100 dziri mukutengeserana. Plustics inonyanya kushandiswa ndeye maPhthalates iyo inogona kukamurwa kuita mapoka maviri akasiyana ezvisikwa zvakasiyana uye zvikamu; Yakadzika Phthalates: Yakadzika molecular uremu (LMW) mapepa ane masere kana mashoma carbon maatomu mumashure mavo emakemikari. Izvi zvinosanganisira, dehp, DBP, Dibp naBBP. Iko kushandiswa kweaya maPhthalate muEurope kunogumira kune zvimwe zvinoshandiswa zvinoshandiswa. High Phthalates: Yakakwira Molecular uremu (HMW) MaPhthalates ndeaya ane 7 - 13 kabhoni maatomu mumashure mavo emakemikari. Izvi zvinosanganisira: dinp, Didp, Dphp, Diup naDtdp. Hmw Phthalates inochengetedzwa zvakachengeteka mune akawanda mazuva ese kusanganisira tambo uye pasi. Vakuru veplasticisers, vakadai sevadaviranisi, vagovates uye mabhureki uye trimlights vanoshandiswa pane zvakakosha zvivakwa zvemuviri zvinodikanwa sekugona kutsungirira zvakanyanya kupisa kana kuti kuchinjika kwakakosha. Zvizhinji zvezvigadzirwa zvePVC isu tinoshandisa mazuva ese asi zvinowanzoita kuti tirongedze zvine phthalate plasticisers. Ivo vanosanganisira zvese kubva pamishini yekurapa sekurapa kwakadai sekurapa kwekurapa uye mabhegi eropa, kune mango etsoka, matanda emagetsi, kurongedza, matoyi, uye matoyi. Mukuwedzera, maPhthates anoshandiswa mune mamwe asiri-PVC application yakadai sekupenda, zvigadzirwa zveRabha, zvinonamatira uye mamwe macometics.
