PVC inozivikanwa sepolyvinyl chloride, tembiricha yayo yekuyerera kwe viscosity uye tembiricha yekudzikira iri padyo, saka zviri nyore mukuita kwemhando dzakasiyana dzekuora, uye nekudaro kurasikirwa nekushandiswa kwekuita.Naizvozvo, zvinodikanwa kuwedzera kupisa kudzikamisa uye lubricant mukugadzirwa kwePVC musanganiswa, yekutanga inovandudza kupisa kwayo, iyo yekupedzisira inoderedza kupokana pakati pePVC molecular cheni, uye kusvibisa simba pakati pePVC kunyunguduka nesimbi, kunatsiridza kuve nyore kwekugadzirisa. PVC mune zvakasiyana-siyana zvigadzirwa.pe wax uye oxidized polyethylene wax ndiwo anowanzo shandiswa muPVC.

Mukugadzirisa kwePVC, hapana kunyungudika kwakachena, zvikamu zvechipiri chete (zvinenge 100μm, zvinoumbwa nezvikamu zvekutanga uye zviputi) zvakakamurwa kuita mabhora maduku (anenge 1μm) uye nodules (anenge 100nm) pasi pechiito chekuveura kwekushisa uye mechanical, nzira iyi inowanzonzi gelation kana plastication.Kuti uwane zvirinani zvemuchina, zvivakwa zvepasi uye processability, chiyero chegelation pakati pe70% ne85% chakakodzera.Iyo gelation process inogona kunonoka kana kukurumidza nekusarudzwa kwakakodzera kwe polyethylene wax.Mushure mekunyunguduka, iyo homogeneous polyethylene wax iripo pakati pekutanga-kurongeka particles kana nodules, iyo inoderedza friction simba pakati pekutanga-order particles kana nodules, nokudaro kuderedza kupisa kwekupisa kwekunyunguduka, kunonotsa plasticization yePVC, uye panguva imwe chete, kugadzikana kwekupisa kwePVC kwakagadziridzwa zvakare.Oxidized polyethylene wax ine kumwe kuenderana nePVC, inogona kunamatira kumusoro kwemanodule, kuwedzera kunyunguduka viscosity, uye ine yakanaka-tuning mhedzisiro pakuita gelation, kuderedza kupokana pakati pekunyunguduka uye michina yekugadziridza yakanaka kuburitsa mumiriri mukati. kugadziridzwa kwePVC, kunyanya mune yakajeka PVC (organotin stabilizer) firimu, ichiwedzera huwandu hwakakodzera hweoxidized polyethylene wakisi haingoridzi kusunungurwa kwakanaka kwazvo, asiwo haideredze kujeka.

Parizvino, kuwedzera kune synthetic pe wax uyeoxidized polyethylene wakisimuPVC, paraffin wax, feto wax uye by-product wax zvakare inoshandiswa zvakanyanya uye inodawo kuchinjika inofananidzwa zvinoenderana neiyo terminal application, Semuyenzaniso, low melting point parafini wax inogona kuita basa rekuzora kwekutanga, munzvimbo yekunyunguduka. ye polyethylene wax, feto wax inogona kuita basa repakati-temu lubrication, yakakwirira kunyungudika ye oxidized polyethylene wax inogona kuita basa rekunonoka kudzosa.Mamwe mafuta anodzivirira kupisa mashoma separafini wax, fatty acid esters, nezvimwewo, zviri nyore kuextrusion zvigadzirwa zvinofa, kutenderedza firimu kutonhora roller deposition.Izvi zvinhu zviri pamusoro pezvivakwa zvekupedzisira zvigadzirwa, pamwe ne-saiti vashandi vanoshanda nharaunda, kugadzirwa kuchava nemhedzisiro yakaipa.Uyezve, lubricant imwe chete muPVC inoenderana yakakwira zvakanyanya, kana kushandiswa kwecomposite lubricant package, izvo zvakasiyana-siyana zveumwe neumwe hazvienderane, mutual reaction, zvakare zviri nyore kutungamira kune compression.Nokudaro, maererano nekushandiswa kwezvigadzirwa zvakadai sekuti kudiwa kwekudhinda, kupfapfaidza, kusarudzwa kwehutano hwakagadzikana, mafuta akanaka ekupisa tembiricha, kuitira kugadzirwa kwakatsetseka uye kuvandudza kunaka kwechigadzirwa kunokosha zvikuru.
Qingdao Sainuo Chemical Co., Ltd.Isu tiri vagadziri vePE wax, PP wax, OPE wax, EVA wax, PEMA, EBS, Zinc/Calcium Stearate….Zvigadzirwa zvedu zvakapfuura REACH, ROHS, PAHS, FDA yekuongorora.
