I-ABS masterbatch yi-masterbatch ekhethekileyo: yenziwe ngeplastiki efanayo neyomphathiswa ngokohlobo lweplastiki oluchazwe ngumsebenzisi wemveliso.Ngokomzekelo, i-PP master kunye ne-ABS master ngokulandelelana bakhetha i-PP kunye ne-ABS njengomthwali.
Umbala we-Universal master: I-resin (ehlala i-PE enendawo ephantsi yokunyibilika) ikwasetyenziswa njengenkxaso, kodwa inokusetyenziselwa ukufaka imibala kwezinye ii-resin ngaphandle kwe-resin yayo yokuxhasa.
I-masterbatch yombala esetyenzisiweyo kufuneka inikele ingqalelo kubudlelwane bokuhlanganiswa phakathi kwezinto zombala kunye nezixhobo zeplastiki kunye nabancedisi.Amanqaku okhetho achazwe ngolu hlobo lulandelayo.(1) izinto zombala azikwazi ukusabela nge-resin kunye nabancedisi abahlukeneyo, ukuchasana okunamandla kwe-solvent, ukufuduka okuncinci, ukumelana nokushisa okulungileyo, njl. Ngamanye amazwi, i-masterbatch ayikwazi ukuthatha inxaxheba kwiindlela ezahlukeneyo zeekhemikhali.Ngokomzekelo, i-carbon black inokulawula ukuphiliswa kweeplastiki ze-polyester, ngoko ke izinto ezimnyama zekhabhoni azinakongezwa kwi-polyester.Ngenxa yokushisa okuphezulu kokulungiswa kweemveliso zeplastiki, umbala wemibala akufanele ubole kwaye utshintshe umbala phantsi kwemeko yokushisa ukubumba.Ngokuqhelekileyo, ii-pigments ze-inorganic ziyakwazi ukumelana nobushushu, ngelixa ii-pigments eziphilayo kunye nedayi zinokumelana nokushisa okungahambi kakuhle, okumele kuhlawulwe ingqwalasela eyaneleyo ekukhetheni iintlobo zemibala.(2) Ukusasazwa kunye namandla ombala wesixhobo sombala kufuneka sibe silungile.Xa ukusasazeka kombala kungafaniyo, kuya kuchaphazela ukubonakala kwemveliso;Xa amandla ombala wezinto zombala ahluphekile, inani lezinto zombala liya kwanda kwaye iindleko zempahla ziya kwanda.Ukusabalalisa kunye namandla ombala wezinto ezifanayo zombala kwii-resin ezahlukeneyo azifani, ngoko kufuneka sinikele ingqalelo kule ngongoma xa sikhetha izinto zombala.Ubungakanani besuntswana lezinto zombala nazo zihambelana nokusasazeka.Ubuncinci ubungakanani bamasuntswana ombala, kokukhona ukusasazwa ngcono kwaye komelele amandla ombala.(3) Ezinye iimpawu zombala zifanele ziqondwe.Umzekelo, kwiimveliso zeplastiki ezisetyenziselwa ukutya kunye namathoyizi abantwana, umbala kufuneka ungabi netyhefu;Kwiimveliso zeplastiki ezisetyenziswa kwizixhobo zombane, izinto zombala ezine-insulation elungileyo zombane kufuneka zikhethwe;Kwiimveliso zeplastiki zangaphandle, kufuneka ukhethe umbala wokumelana nokuguga kwemozulu, njl.
