Polyethylene wakisiimhando ye polyolefin synthetic wax, iyo inowanzoreva homopolyethylene ine huremu hwemamorekuru husingasviki 10000. Mupfungwa yakafara, ethylene mapolima asina kusimba uye kusimba uye haakwanise kugadzirwa sechinhu chimwe chete anogona kunzi polyethylene wakisi.Pe waxine yakakwira yakapfava poindi, yakaderera kunyunguduka viscosity, yakanaka kugadzikana kwekemikari, lubricity yakanaka uye fluidity.Seyamuro yekugadzirisa, inoshandiswa zvakanyanya muPVC pombi, mafirimu, tambo uye zvimwe zvepurasitiki uye zvigadzirwa zverabha kuvandudza mashandiro ezvigadzirwa uye kuvandudza kutaridzika kwezvakapera zvigadzirwa.

Kugadzirira nzira ye polyethylene wax
Pane nzira nhatu huru dzekugadzira pe wakisi.Yekutanga ndeye polyethylene kutsemuka nzira, iyo inopwanya polyethylene resin kuita polyethylene wakisi ine yakaderera molecular huremu pakupisa kwepamusoro.Chechipiri inzira yekunatsa ne-chigadzirwa, iyo inounganidza zvigadzirwa zvepasi molecular uremu zvikamu zvinogadzirwa mukugadzirwa kwe ethylene polymerization uye kuvanatsa kuti vawane polyethylene wax.Nzira yechitatu ndeye ethylene synthesis nzira, iyo inogadzirisa zvakananga polyethylene wakisi ine ethylene seyakagadzirwa.Nhasi, Sainuo ichakutora iwe kuti udzidze nezve polyethylene wakisi yakagadzirwa nenzira yekupwanya uye nzira yekubatanidza.

(1) Kugadzirira kwe polyethylene wax ne pyrolysis
Kutsemuka nzira ndiyo nzira huru yekugadzira polyethylene wakisi muChina.High molecular huremu pure polyethylene kana tsvina polyethylene purasitiki akatsemurwa mu polyethylene wakisi pakupisa.Hunhu hwayo hwechigadzirwa uye zvivakwa (zvakadai sekuoma, nzvimbo yekunyungudika uye inooneka ruvara) zvinokanganiswa zvakanyanya nekwakabva kupaza mbishi zvinhu.Iyo nzira yekupwanya ine tekinoroji yakapusa, sosi yakapfuma yezvigadzirwa uye mutengo wakaderera wekushanda.Inogona kuona kushandiswazve kwemarara polyethylene ine zvakanaka zvehupfumi mabhenefiti.Zvisinei, maitiro ekuputika akaoma kudzora, kugoverwa kwema molecular kwechigadzirwa kwakafara, kunaka kwe polyethylene wax kwakaoma kudzora, uye mavara akawanda matema anogadzirwa.Iyo yakakurumbira pakati uye yakaderera-yekupedzisira application senge colorbatch color.
Iyo iripo yekupwanya maitiro anosanganisira thermal cracking, solvent inobatsira kuputika uye catalytic cracking.Pakati pavo, kupisa kwemafuta ndiko kuri nyore.Polyethylene wakisi zvigadzirwa zvinogona kugadzirwa nekudzora kuita tembiricha uye nguva, asi yakawanda simba rekushandisa rinodiwa.Vanhu vanobva kuBeijing University yemakemikari tekinoroji vakadzidza kugadzirira kwepolyethylene wax nekupwanya PE resin pakupisa kwakanyanya mune imwe screw extruder.Iyo heater inowedzerwa papombi yekubatanidza pakati peiyo extruder uye tangi yekutonhora kupisa uye kutsemura zvinhu.Iyo yakakwana yekutsemuka tembiricha i420 ℃, uchiona kuenderera mberi kwekugadzirwa kwePE resin kugadzirira polyethylene wakisi.Vamwe vakadzidza kugadzirwa kwepolyethylene wax nekupwanya tsvina yepolyethylene mune autoclave ine al-mcm-48 seyamuro.Kubata tembiricha ndeye 360 ​​~ 380 ℃ uye nguva yekuita ndeye 4H.Iko kushandiswa kwecatalyst kunoderedza kuita activation simba, tembiricha inodiwa pyrolysis uye kushandiswa kwesimba.Wang Lulu nevamwe vakavandudza goho re polyethylene wax ne solvent inobatsira pyrolysis ye polyethylene tsvina mapurasitiki.Migumisiro yezvinonyungudutsa zvakasiyana uye mamiriro ekuita pagoho uye maitiro ewakisi zvakaongororwa.Muedzo unoratidza kuti goho repolyethylene wakisi rinogona kuvandudzwa nekushandisa zvinonyungudutsa zvinonhuhwirira.Paunenge uchishandisa yakasanganiswa xylene se solvent, goho rinosvika pa87.88%.Zvinonhuhwirira zvinonyungudutsa zvinogonawo kuvandudza kunaka kwechigadzirwa kusvika kumwero wakati uye kuwana mwenje weyero polyethylene wakisi.

(2) Synthesis ye polyethylene wax
Polyethylene wakisi yakaitwa yakananga kubva kuethylene ine kuchena kwepamusoro, diki diki remamorekuru uremu kugovera, nhete yekunyungudika, inogadziriswa chigadzirwa kuita uye yakagadzikana mhando.Inoshandiswa kugadzira yakakwirira-mhando uye yakasiyana-siyana polyethylene wakisi.Zvinoenderana nemaitiro epolymerization uye marudzi ezvinokonzeresa anoshandiswa, ethylene synthesis inogona kukamurwa kuita yemahara radical polymerization, Ziegler Natta (ZN) catalytic polymerization, metallocene catalytic polymerization zvichingodaro.
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!
