Colour masterbatch (yomwe imadziwikanso kuti color masterbatch) ndi gulu lomwe limapezeka pokweza mitundu yosiyanasiyana yamitundu yambiri kapena utoto mu resin.Amapangidwa ndi zigawo zitatu: inki (kapena utoto), zonyamulira ndi othandizira othandizira.kukhazikika, kotero mphamvu yake yopendekera ndiyokwera kuposa pigment yokha.
Zofunikira za Masterbatch:
1. Tona: Inki yochulukira kwambiri (kapena utoto) itha kugwiritsidwa ntchito kupanga ma masterbatches apadera amitundu kapena ma masterbatches amitundu yosiyanasiyana a mapulasitiki osiyanasiyana;ndizothekanso kukonzekera mitundu yoyenerera ndikusakaniza inki ndi chonyamulira cha masterbatch molingana ndi chiŵerengero cha chilinganizo.Kupyolera mu kutentha, pulasitiki, kugwedeza ndi kumeta ubweya wa granulator, mamolekyu a pigment ndi ma molekyulu a utomoni wonyamulira potsirizira pake amaphatikizidwa kuti apange tinthu tating'onoting'ono tofanana ndi tinthu ta utomoni, ndiko kuti, mtundu wa masterbatch.
Ambiri ntchito organic inki ndi: koji wofiira cyani buluu cyanine wobiriwira lightfast wofiira macromolecular wofiira, macromolecular okhazikika chikasu, okhazikika wofiirira, azo red ndi zina zambiri ntchito inorganic pigments ndi mphika wofiira poto yellow, titaniyamu woipa, carbon Iron okusayidi wofiira, chitsulo okusayidi yellow, ndi zina.
2. Chonyamulira: Chonyamulira chapadera cha masterbatch ndiye maziko a mtundu wa masterbatch.Nthawi zambiri, utomoni womwewo monga utomoni wamankhwala umasankhidwa ngati chonyamulira, kotero kuti kugwirizana kwa ziwirizo ndikwabwino, koma fluidity ya chonyamulira iyeneranso kuganiziridwa.
3. Zothandizira: makamaka zimaphatikizapo dispersants, coupling agents, compatibilizers, etc. kulimbikitsa yunifolomu kubalalitsidwa kwa pigment ndi osakhalanso mgwirizano.Malo osungunuka a dispersant ayenera kukhala otsika kuposa a resin, ndipo amagwirizana bwino ndi utomoni komanso kuyanjana kwabwino kwa pigment.Ma dispersants omwe amagwiritsidwa ntchito kwambiri ndi polyethylene low molecular weight waxes ndi stearates.
Zowonjezera zina, monga zoletsa malawi, zowunikira, antibacterial agents, antistatic agents, antioxidants, etc., zitha kuwonjezeredwa ku masterbatch yamtundu.Pokhapokha ngati kasitomala atapempha, mtundu masterbatch ilibe zowonjezera pamwambapa.
