Kushandiswa kwe pe wax sezvo pigment dispersant muruvara masterbatch muChina yakatanga muna 1976, apo yainyanya kugadzirwa ne-high-density polyethylene polymerization. Polyethylene wakisi yakagadzirwa nepyrolysis nzira yakatanga muna 1980 uye yave kushandiswa nhasi.

Masterbatch i pigment concentrate ine resin semutakuri.Pigments iripo mumatunhu matatu: primary particles, aggregates uye aggregates.The dispersion mechanism yemidziyo yakasvibirira inzira umo ma agglomerate particles anotsemuka kuita agglomerates uye primary particles, uye zvichangobva kugadzirwa zvimedu zvinobva zvadzikamiswa.

Iyo nzira yekuparadzira ye pigment mu resin inogona kutsanangurwa nematanho matatu anotevera: chekutanga, resin inonyunguduka inonyorovesa pamusoro pe pigment aggregates uye inopinda mukati memukati pores;Chechipiri, muunganidzwa wakaputsika pasi pekukanganisa uye kudhumhana pakati pesimba rekugera rekunze uye pigment particles;Pakupedzisira, iyo ichangobva kuumbwa pigment particles inonyoroveswa uye yakaputirwa neresin melt, iyo yakagadzikana isina agglomeration.Aya matanho matatu anogona kungoratidzwa se: lubrication - kupwanya - kudzikamisa.

Iyo resin inonyunguduka ine yakakwira viscosity uye kusawirirana kwakashata nepigment pamusoro, saka haina kunyorova uye yakaoma kupinda mukati me pores yeaggregate, saka haigone kutamisa zvinobudirira simba rekugera uye inonetsa kutyora muunganidzwa.Kunyangwe mushure mekunge sumbu raputswa, resin inonyungudika haigone kukurumidza kunyorova uye kudzivirira iyo nyowani, uye kudhumhana kunobata kunoita kuti zvimedu zviunganidzwe zvakare.Kugadzirisa dambudziko iri, polyethylene wax inogona kuwedzerwa kune iri pamusoro system.Munguva yekugadzira masterbatch system ine polyethylene wax, polyethylene wakisi inotanga kunyungudutswa neresin uye yakaputirwa pamusoro pe pigment.

Nekuda kwekuderera kwayo uye kugarisana kwakanaka nemavara, polyethylene wakisi iri nyore kunyorovesa pigment uye kupinda mukati memukati mapores e pigment masumbu, kuderedza kubatana, kuita pigment aggregates nyore kuvhurika pasi pemhedzisiro yekunze kweshear force, uye zvimedu zvichangobva kuumbwa. inogonawo kukurumidza kunyorova uye kudzivirirwa.Uye zvakare, polyethylene wakisi inogona kuita basa mukudzikisa viscosity yehurongwa nekuvandudza fluidity.Naizvozvo, kuwedzera polyethylene wax mu masterbatch kugadzirwa kunogona kuvandudza kugona kwekugadzira, kuwedzera kuburitsa, uye kubvumidza yakakwira pigment concentration.
Qingdao Sainuo Chemical Co., Ltd.Isu tiri kugadzira PE wakisi, 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!
