Ukusabalala kwemibala kuyinselele ebalulekile kodwa evame ukunganakwa ekukhiqizweni kwe-masterbatch. Ukusabalala okubi kungaholela ezinkingeni ezifana nokusabalala kombala okungalingani, izihlungi ezivalekile, ukuphuka kwefayibha kumafayibha aspun, kanye nemithungo ehlanganisiwe ebuthakathaka. Lezi zinkinga azithinti nje kuphela ikhwalithi yomkhiqizo kodwa futhi zandisa izindleko zokukhiqiza ngenxa yokusetshenziswa okuphezulu kwemibala kanye nesikhathi sokungasebenzi kwemishini. Ngezansi umhlahlandlela omfushane wokubhekana nalezi zinselele ngempumelelo, ngokusekelwe emikhubeni yemboni:

1. Lungiselela Ukukhethwa Kwe-Pigment
Khetha Ama-Pigment Ahambisanayo: Khetha ama-pigment ahambisana nesisekelo se-polymer (isb., i-PE, i-PP, i-PET) ukuqinisekisa ukuthi kumanziswa kahle futhi kusakazeka kahle.

Usayizi Wezinhlayiya Nokwelashwa Komphezulu: Sebenzisa imibala enobukhulu bezinhlayiya ezincane ukuze usakazeke kangcono. Imibala ehlanzwe umphezulu (isb., ngezihlanzi noma izimbozo) isiza ekunciphiseni ukuhlangana futhi ithuthukise izakhiwo zokugeleza.

Ukulayisha Umbala: Gwema ukudlula umthwalo wombala onconywayo (ngokuvamile u-20-40% wemibala ephilayo, u-50-80% wezinto ezingaphili). Ukulayisha ngokweqile kungabangela ukuhlangana kanye nokuhlakazeka okubi.

2. Thuthukisa Ukuxuba Nokuhlanganisa
Ukuxuba Okushefa Kakhulu: Sebenzisa ama-extruder amabili noma ama-mixer ashefa kakhulu ukuze uhlukanise ama-pigment agglomerate. Lungisa ukucushwa kwezikulufo (isb., amabhlogo okuxova) ukuze ulungise ukugunda nokuthuthukisa ukuhlakazeka.

Ukuxuba Ngaphambi Kokuxuba: Hlanganisa imibala nezihlanzi noma ama-carrier resins ngaphambi kokukhipha ukuze uthuthukise ukumanzisa kokuqala nokunciphisa ukuhlangana.

Ukulawula Izinga Lokushisa: Gcina amazinga okushisa ancibilikayo afanele ukuze ugweme ukuwohloka kombala noma izinkinga ze-viscosity. Kuma-pigment azwela ukushisa (isb., ama-pigment athile e-organic), gcina amazinga okushisa engaphansi komkhawulo wawo wokuwohloka.

3. Sebenzisa ama-Dispersing Agents
Izithasiselo: Faka izinto ezihlakazayo ezifana nama-waxes, ama-stearates, noma ama-polymeric dispersants (isb., i-polyethylene wax, izithasiselo ezisekelwe ku-EVA) ukuze unciphise i-viscosity futhi uthuthukise ukumanzisa kwe-pigment.
Isilinganiso: Ngokuvamile, sebenzisa i-dispersant engu-1-5% ngesisindo, kuye ngohlobo lwe-pigment kanye nomthwalo. Ukusetshenziswa ngokweqile kungathinta kabi izakhiwo zemishini futhi kungabangela ukuqhakaza (inkinga yokubukeka kobuso).
I-Hyperdispersant Entsha ye-Masterbatch: Uchungechunge lwe-SILIKE SILIMER – Izinsiza zokucubungula ezisebenza kahle kakhulu kanye nama-ejenti okuhlakaza.

Uchungechunge lwe-SILIKE SILIMERIzinsiza Zokucubungula kanye Nama-ejenti Okusabalalisaama-wax asekelwe ku-silicone esizukulwaneni esilandelayo (abizwa nangokuthi ama-Silicone Hyperdispersants) aklanyelwe ukuletha ukusabalalisa kombala okuphezulu kanye nokugcwaliswa kokugcwalisa ekukhiqizweni kwe-masterbatch. Ilungele ukugxila kombala, ama-compounds agcwalisiwe, amapulasitiki obunjiniyela, kanye nezinqubo zokusabalalisa ezidingakalayo. Lawa ma-hyperdispers athuthukisa ukuzinza kokushisa, i-rheology, kanye nokusebenza kahle kwezindleko ngenkathi esusa izinkinga zokufuduka ezivamile ezithasiselweni zendabuko (isb., ama-wax, ama-amides, ama-esters).

4. Lungisa Amapharamitha Okucubungula

Isivinini sesikulufu: Khulisa isivinini sesikulufu (ngokuvamile esingu-200-500 rpm) ukuze uthuthukise ukucheba nokuhlakazeka. Gwema isivinini esikhulu, njengoba lokhu kungaholela ekuwohlokeni kokushisa.

Isikhathi Sokuhlala: Lungiselela isikhathi sokuhlala ku-extruder (ngokuvamile imizuzwana engama-30-60) ukuqinisekisa ukuxubana kahle ngaphandle kokushisa ngokweqile.

Ukuhlunga: Sebenzisa amaphakethe esikrini (isb., i-mesh engu-100-200) ukususa izinhlayiya ezingahlakazekile nokuqinisekisa ikhwalithi efanayo ye-masterbatch.

5. Bhekana Nezinkinga Zemishini Nokunakekelwa

Imishini Ehlanzekile: Hlanza njalo izinto zokukhipha izinto, izikulufo, kanye nezimfa ukuze uvimbele ukungcola noma ukunqwabelana kwezinto ezonakele ezithinta ukusabalala.

Ukuhlola Ukugqoka: Hlola izikulufo nama-barrel ukuthi agugile yini, njengoba imishini egugile inciphisa ukusebenza kahle kokucheba futhi iholela ekuhlakazekeni okubi.

Ukunemba Kokuphakela: Sebenzisa iziphakeli ze-gravimetric ukuze uthole isilinganiso esinembile sombala kanye ne-resin, uqinisekise ukuhambisana kokusabalala kombala.
