I-PP/PE/ABS/PET Masterbatches enziwe ngokwezifiso Ayamukeleka

1. Yenza i-pigment ibe nokuhlakazeka okungcono emkhiqizweni.Ama-pigments kumele acwengwe ohlelweni lokukhiqizwa kwe-masterbatch ukuze kuthuthukiswe ukuhlakazeka kanye namandla ombala wezingulube.I-resin ethwala i-masterbatch yombala ekhethekile iyafana ngokuyisisekelo nohlobo lwe-resin yomkhiqizo, ngakho inokuhambisana okuhle futhi ingancibilikiswa ibe yizinhlayiya ze-pigment ngokushisisa futhi ihlakazwe emikhiqizweni yepulasitiki.
2. Qinisekisa ukuzinza kombala womkhiqizo.Isimo sezinhlayiyana zezinhlayiyana eziyinhloko zombala siyefana naleso sezinhlayiyana ezinemibala ye-resin, elula kakhulu futhi enembile ukukala.Ngeke inamathele esitsheni lapho ixutshwe, futhi ihlanganise kahle ne-resin.Ngakho-ke, ukuzinza kwenani elingeziwe kungaqinisekiswa, ngokungafani nokwengezwa komkhondo wezindawo ze-pigment.Iphutha elincane enqubweni yokulinganisa noma yokusebenza lizodala umehluko wombala, ukuze kuqinisekiswe ukusimama kombala womkhiqizo.

3. Gwema ukungcolisa imvelo.
4. Kulula ukuyisebenzisa.
Okwesibili, yikuphi ukwakheka okuyinhloko kwe-masterbatch yombala?
Ngokuvamile, ama-masterbatches ombala akhiwe ngokuyinhloko nge-colorant, carrier kanye ne-disperant.
1. I-Colourant colorbatch iyingxenye ebaluleke kakhulu.Umbala osetshenziswa ku-polyolefin, i-PVC namanye ama-masterbatches ombala yi-pigment, futhi izingulube ezihlukahlukene ezinezakhiwo ezahlukene zingakhethwa ngokuvumelana nokusetshenziswa okuhlukene.Ama-masterbatches opulasitiki bobunjiniyela angaba odayi abancibilikayo, abanye obala bemibala bemvelo bezinga eliphakeme kanye nombala we-inorganic ukumelana nokushisa okuphezulu.Ngokuvamile, odayi akufanele basetshenziselwe ukufaka umbala we-polyolefin, ngaphandle kwalokho kuzodala ukufuduka okukhulu.
2. I-dispersant ikakhulukazi imanzisa ingaphezulu le-pigment, elivumela ukuthi liqhubeke lihlakaza i-pigment nokuyiqinisa ku-resin.Ngesikhathi esifanayo kufanele kube ukuhambisana okuhle ne-resin, akuphazamisi ikhwalithi yemikhiqizo yombala.I-wax ye-polyethylene enesisindo esiphansi se-molecular noma i-zinc stearate ngokuvamile isetshenziswa njengezisabalalisi ze-polyolefin masterbatches.Amapulasitiki wobunjiniyela umbala we-masterbatch dispersing agents ngokuvamile i-polar low molecular weight polyethylene wax, zinc stearate, calcium stearate nokunye.
3. Isithwali senza i-pigment isatshalaliswe ngokulinganayo futhi izinhlayiyana ze-masterbatch zombala ziyi-granular.Ukuhambisana ne-resin yombala kanye nokuhlakazeka okuhle kwe-masterbatch yombala kufanele kucatshangelwe ekukhetheni inkampani yenethiwekhi.Ngakho-ke, i-fluidity yesithwali kufanele ibe nkulu kunaleyo ye-resin, futhi ayithinti ikhwalithi yomkhiqizo ngemva kombala.Uma i-polymer efanayo enenkomba enkulu yokuncibilika ikhethiwe, inkomba yokuncibilika kwe-master particle iphakeme kunaleyo ye-polymer enemibala, ukuze kuqinisekiswe umbala ofanayo kanye nokucwebezela komkhiqizo wokugcina, ngaphandle kwe-moire esobala nomugqa.
