Polyethylene wakisiihupfu huchena huine hunyoro hunosvika 100-117 ℃.Nekuda kwehukuru hwayo huremu hwemamorekuru, yakakwirira kunyungudika uye kuderera kuderera, inoratidzawo pachena lubrication maitiro pakupisa kwakanyanya uye shear rate.Iyo yakakodzera kune yakaoma PVC imwe uye mapatya-screw extrusion, ine yakajairika huwandu hwe0.1-0.5phr.

Munguva yekugadzirwa kwePVC pombi profiles, pachava nechiitiko chekusajeka uye kupenya kwakashata.Parafini, sePVC lubricant, ine yakaderera kupfava poindi uye kusapararira zvakanaka.Nekuda kwekushisa kwakanyanya mukuita kwekugadzira, parafini inonyungudika uye inoputika kuita gasi.Izvo zvakaoma kuti parafini iite basa mukushandiswa kwePVC pombi.Iyo yekuparadzira maitiro haina kunaka, uye iyo PVC pombi profiles ichave yakasvibiswa kubva pamusoro.
PVC pombi profiles inogadzirwa ne polyethylene wax (PE wax) haizove nematambudziko akadaro, nekuti iyo inopfavisa nzvimbo yepolyethylene wax huni muviri yakakwira, uye pasi pemamiriro ekushisa kwakanyanya, polyethylene wax (PE wax) inongove mvura, ine yakakwira viscosity uye kusaparadzirwa zvakanaka kwewakisi yepolyethylene (PE wax), asi kupenya kwakanaka kwazvo.Kana viscosity yepolyethylene wax (PE wax) yakaderera, kupararira kwakanaka kwazvo uye kupenya kwakanaka.
Qingdao Sainuowakisi ye polyethyleneyakaisa kabhoni kugovera, yakadzika mamorekuru uremu kugovera, kuderera kwehuremu kuderera uye kwakanaka kwekutanga, kwepakati uye kunonoka kuita kwemafuta.Low viscosity, high softening point, hombe molecular huremu, kunaka kugadzikana kwemafuta, kunhuhwirira kwakanaka kwekunze uye kudzora kwakasimba kwemukati.Zviri nyore kuparadzira, izvo zvinogona kuvandudza zvakanyanya kupenya kwezvigadzirwa;Kugarisana kwakanaka, kunoenderana nezvakawanda zvigadzirwa uye anti precipitation;Kuita kwakanaka kwedemoulding, nguva yakareba inoenderera yekugadzira uye zvimwe zvakanaka, zvine hunhu hwakanaka.Isu tichasarudza yakakodzera polyethylene wakisi zvinoenderana nezvinodiwa zvakasiyana zvevatengi.

Polyethylene wakisi ine polar centre yakasimba kwazvo uye refu isiri polar carbon chain.Muchimiro che polyethylene wax, chikamu chinopindirana nepurasitiki mu polarity chinotamba basa rekuzora mukati, uye chikamu chisingaenderane nepurasitiki mu polarity chinotamba basa rekuzora kwekunze uye kudhiza.
Kuiswa kwakakosha kwewakisi yepolyethylene kuri mukugadziriswa kwePVC.Kana ichienzaniswa nemafuta acid ekuzora, polyethylene wakisi haina kukanganisa kunyungudika kunyunguduka uye Vicat kupfavisa poindi, uye inopa yakanakisa anti adhesion uye kuyerera kuyerera.Munzira dzakakosha dzekugadzirisa, PE wakisi inogona kushandiswa kudzora kunyungudika.Kunyange kana mari yacho yakakura, inogona kuva nekuenderana kwakanaka nezvimwe zvikamu.
Polyethylene wax ndiyo chete inozivikanwa yepurasitiki lubricant iyo inogona zvese mukati nekunze lubrication (demoulding effect), kuchengetedza kujeka kwakanyanya uye kusaita zvishoma pane gelation.Pamusoro pezvo, kuderera kuderera kwePE wax kwakakosha zvakanyanya kune calendering uye vacuum degassing,.
Semafuta emukati, polyethylene wakisi ine kuenderana kwakanaka nemapolima.Inoita basa mukudzikisa kubatana pakati pemamorekuru epolymer mupolymer, kuitira kuti ivandudze kugadzirwa kwemukati kwekupokana kwekupisa uye kunyunguduka kunyungudika kwepurasitiki.
Basa rePE wakisi semafuta ekunze rinonyanya kuvandudza kukweshera pakati pepolymer melt uye inopisa simbi pamusoro pemidziyo yekugadzirisa.Iyo ine kusawirirana kwakashata nepolymer uye iri nyore kutama kubva mukunyunguduka kuenda kunze, saka inogona kuumba yakaonda yakatetepa layer painterface pakati pepurasitiki kunyunguduka nesimbi.
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!
