Zvigadzirwa zvePVC zvakaoma zvinosanganisira mapaipi ePVC, mafittings, profiles, uye mahwendefa.Nekuda kweiyo viscosity yakakwira uye kuyerera kwakashata kwePVC yakaoma, kunyangwe nekuwedzera simba rekunze uye tembiricha, shanduko yekuyerera haina kukosha.Uye zvakare, tembiricha yekuumba yePVC resin iri padyo zvakanyanya nekushisa kwekupisa tembiricha, uye tembiricha yekuumba inogumira, zvichiita kuti zviome kugadzira zvinhu.Saka mukugadzirisa kwePVC zvigadzirwa zvakaoma, zvinodikanwa kuwedzera zvimwe zvinoshanda, senge zvinosimbisa, mafuta ekuzora(PE wax,OPE wakisi), nezvimwewo.

MuPVC sisitimu, yakaderera density oxidized polyethylene wakisi inogona kuiswa plasticized pamberi penguva, uye gare gare torque inoderedzwa.Iyo ine yakanakisa mukati nekunze lubrication.Inogona kuvandudza kupararira kwemavara, kupa zvigadzirwa kupenya kwakanaka uye nekuvandudza kugadzirwa kwakanaka.
Oxidized polyethylene wakisiine yakaderera viscosity, yakanaka kuoma, uye yakanaka kugadzikana kwekupisa, uye inogona kuwedzerwa semafuta ekuzora mukugadzirisa kwePVC yakaoma zvigadzirwa.Semafuta, makemikari ayo akagadzikana uye ayo emukati uye ekunze lubrication maitiro paPVC ane mwero.

Panguva imwecheteyo, kuwedzera oxidized polyethylene wakisi kunogonawo kuwedzera mamwe mabasa ebetsero, kukurudzira kudhirowa mukukunguruka kweextrusion process, kuderedza kukweshera pamidziyo, uye kuwedzera hupenyu hwebasa remidziyo.
Oxidized pe wax ine yakakwirira kunyungudika uye inogona kuchengetedza yakanaka kunyunguduka viscosity panguva yepamusoro-tembiricha kugadzirisa kwePVC;Pasina kukanganisa kutaridzika kwechigadzirwa, kuwedzera nguva yepurasitiki kunobatsira pakuumba, kuwedzera extrusion kumhanya, uye kuvandudza kupenya kwechigadzirwa.

Kuwedzera huwandu hwakakodzera hweoxidized polyethylene wakisi kune fomula yezvakaoma PVC inoonekera zvigadzirwa kazhinji hazvikanganisi kubuda pachena kwechigadzirwa.
