Customized PP/PE/ABS/PET Masterbatches Yamkelekile
1. Yenza i-pigment ibe ne-dispersibility engcono kwimveliso.Ii-pigments kufuneka zicocwe kwinkqubo yokuvelisa i-masterbatch ukuze kuphuculwe i-dispersibility kunye namandla ombala wee-pigments.I-resin ephetheyo yombala okhethekileyo we-masterbatch ngokusisiseko iyafana nohlobo lwe-resin yemveliso, ngoko iyahambelana kakuhle kwaye inokunyibilika ibe ngamasuntswana e-pigment ngokufudumeza kunye nokusasazwa kwiimveliso zeplastiki.
2. Qinisekisa ukuzinza kombala wemveliso.Ubume be-particle master master particle bufana ne-particle ye-resin enemibala, elula ngakumbi kwaye ichanekile ukulinganisa.Ayiyi kubambelela kwisitya xa ixutywe, kwaye idibanise kakuhle ne-resin.Ke ngoko, ukuzinza kwesixa esongezelelweyo kunokuqinisekiswa, ngokungafaniyo nokongezwa komkhondo weendawo ze-pigment.Impazamo encinci kwinkqubo yokulinganisa okanye ukusebenza iya kubangela ukuhluka kombala, ukwenzela ukuba kuqinisekiswe ukuzinza kombala wemveliso.
3. Kuphephe ukungcolisa okusingqongileyo.
4. Kulula ukuyisebenzisa.
Okwesibini, yintoni eyona nto iphambili yombala we-masterbatch?
Ngokubanzi, ii-masterbatches zemibala zenziwa ikakhulu nemibala, umthwali kunye ne-disperant.
1. Umbala we-colorant masterbatch lelona candelo libalulekileyo.Umbala osetyenziswa kwi-polyolefin, i-PVC kunye neminye i-masterbatches yombala yi-pigment, kwaye ii-pigments ezahlukeneyo ezineempawu ezahlukeneyo zinokukhethwa ngokusetyenziswa okwahlukeneyo.Ii-masterbatches zeeplastiki zobunjineli zinokuba ziidayi ezinyibilikayo, ezinye ii-pigments ezikumgangatho ophezulu kunye nezinye i-pigments ezinganyangekiyo kubushushu obuphezulu.Ngokuqhelekileyo, iidayi akufanele zisetyenziswe kwi-polyolefin coloring, kungenjalo iya kubangela ukufuduka okukhulu.
2. I-disperant ikakhulu imanzisa ubuso be-pigment, eyenza ukuba iqhube ngakumbi ukusabalalisa i-pigment kunye nokuzinzisa kwi-resin.Ngexesha elifanayo kufuneka kube nokuhambelana kakuhle kunye ne-resin, ayichaphazeli umgangatho weemveliso zombala.Ubunzima bemolekyuli ephantsi i-polyethylene wax okanye i-zinc stearate zisetyenziswa ngokubanzi njengezisasazi ze-polyolefin masterbatches.Iiplastiki zobunjineli bemibala ye-masterbatch echithachithayo idla ngokuba yi-polar low molecular weight polyethylene wax, zinc stearate, calcium stearate njalo njalo.
3. Umthwali wenza i-pigment isasazwe ngokulinganayo kwaye umbala we-masterbatch particle is granular.Ukuhambelana ne-resin yombala kunye ne-dispersibility efanelekileyo ye-masterbatch yombala kufuneka ithathelwe ingqalelo ekukhetheni umthwali.Ngoko ke, umbane we-carrier kufuneka ube mkhulu kune-resin, kwaye awuchaphazeli umgangatho wemveliso emva kombala.Ukuba i-polymer efanayo kunye nesalathisi esikhulu sokunyibilika sikhethiwe, isalathisi sokunyibilika kwe-master particle iphezulu kunepolymer enemibala, ukwenzela ukuba kuqinisekiswe umbala ofanayo kunye nokukhanya kwemveliso yokugqibela, ngaphandle kwe-moire ecacileyo kunye nomgca.
