Heat stabilizer ndechimwe chezvikamu zvakakosha zveplastic processing additives. Nekuda kwekusagadzikana kwePVC kwePVC, magadzirirwo anowirirana anofanirwa kuwedzerwa kugadzirisa kukanganisa kwePVC cheni uye kutora HCl inogadzirwa nePVC dechlorination nenguva. Kuberekwa uye kuvandudzwa kwekupisa kwekushisa kunopindirana nePVC resin, iyo inonyanya kushandiswa muPVC resin processing. Naizvozvo, kupisa kudzikamisa kwakabatana zvakanyanya nechikamu chePVC resin uye zvinyoro uye zvakaoma zvigadzirwa muPVC. Mukugadzira uye kugadzirisa kupisa stabilizer, lubricant ( polyethylene namo ) inokoshawo. Iyo yakanaka lubrication system ine yakaderera volatility, yakanaka dhizaini uye kuyerera kwekuita, uye inogona kuvandudza yakakwirira-tembiricha kugadzikana kweiyo stabilizer, kurebesa kugadzikana kwekupisa nguva, kuderedza kunaya kwetsvina uye kunatsiridza kuramba kwemamiriro ekunze kwechigadzirwa.

Calcium zinc composite stabilizer imwe yezvidziviriro zvekupisa. Iyo lubrication system ye calcium zinc composite stabilizer inobva pane zvinodhura zvinhu. Makambani mazhinji anoshandisa wakisi yepolyethylene sewakisi yekuzora. Sainuo pe wakisi inogona kunyatso kuvandudza fluidity yePVC kupisa inodzikamisa process process, kuwedzera extrusion kunyatsoshanda kwePVC zvigadzirwa uye kunatsiridza kupenya kwepasi kwezvigadzirwa; Inogona kunyatso kudzora chiitiko che agglomeration mukugadzirisa kwePVC heat stabilizer; Uye zvinobudirira kugadzirisa iyo precipitation phenomenon yePVC heat stabilizer mukugadzirisa zvigadzirwa.
Polyethylene wax, kureva PE wakisi, yakaderera molecular uremu polyethylene, yakananga polymerized kubva ethylene. Zvigadzirwa zvakasanganiswa neakasiyana ekugadzira maitiro uye catalytic masisitimu akasiyana muhuremu hwemamorekuru, kugovera huremu hwemamorekuru uye chimiro checheni, uye kuita kwezvigadzirwa zvinoenderana kuchave kwakasiyana zvakanyanya. PE wakisi inowanzova hupfu chena, ine avhareji yemamorekuru huremu hwe1500-5000 uye nzvimbo yekunyungudika ye100-120 madhigirii. Iyo ine yakanakisa yekunze lubrication maitiro muPVC kugadzirisa, uye inogona zvinobudirira kuvandudza fluidity, goho, kupararira, kupenya kwepamusoro uye dhizaini yePVC kugadzirisa. Nekuda kwehuremu hwayo hukuru hwemamorekuru, nzvimbo yekunyungudika uye yakanaka kugadzikana kwekushisa kwepamusoro, inoratidza kusimba kwekunze kwekuzora pasi petembiricha yakanyanya uye yakakwirira shear mamiriro.

Zvigadzirwa zve polyethylene wakisi zvinogona kunyatso kuvandudza kugadzikana kwekupisa kwePVC uye kunyungudika mukugadzirisa, kuwedzera extrusion yezvigadzirwa zvePVC, kunatsiridza kupenya kwezvigadzirwa, uye kudzikisa zvinobudirira chiitiko chekunaya mukugadzirisa kwezvigadzirwa zvePVC.

Parizvino, akawanda PE wax mumusika wepamba akakamurwa kuva akati wandei marudzi:
1. PE wax inogadzirwa ne ethylene homopolymerization. Iyo PE wakisi inogadzirwa neiyi nzira ine yakanaka yekunze lubrication performance, yakakwirira gloss, nhete mamorekuru kugovera uye yakagadzikana hunhu.
2. The by-chigadzirwa che ethylene polymerization process, inowanzo zivikanwa se sub brand wax, iPE wakisi inocheneswa kuburikidza nekunatswa. Chigadzirwa chacho chine yakaderera viscosity, yakakwira kunyungudika, yakanakisa yekunze lubrication kuita uye mutengo wakaderera, asi mhando inochinja nekuchinja kwezvinhu mbishi uye maitiro. Nekuda kwehunhu hwekunatsa nzira, hazvigoneke kuti pave neakanyanya kunyungudika zvikamu zvechigadzirwa.
3. PVC thermal stability yakaderera molecular weight polyethylene cracking product, inowanzonzi kuputika wakisi, nzira yekupwanya iri nyore uye iri nyore kushanda, asi kuparadzirwa kwema molecular echigadzirwa kunochinja-chinja nemagadzirirwo echigadzirwa, mhando yacho yakanaka, uye ipapo. ichave ichiri chikamu chidiki cheyakaderera melting point components.
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. Sainuo zorora wakavimbiswa wakisi, gamuchira kubvunza kwako!
