Ukuhlakazwa kwe-pigment kuyinselelo ebucayi kodwa evame ukubukelwa phansi ekukhiqizeni i-masterbatch. Ukuhlakazeka okungekuhle kungaholela ezinkingeni ezifana nokusatshalaliswa kombala ongalingani, izihlungi ezivalekile, ukuphuka kwefayibha kuma-spun fibers, nama-welded seams abuthakathaka. Lezi zinkinga azithinti kuphela ikhwalithi yomkhiqizo kodwa futhi zandisa izindleko zokukhiqiza ngenxa yokusetshenziswa okuphezulu kwe-pigment kanye nokuphelelwa yisikhathi kwemishini. Ngezansi umhlahlandlela omfushane wokubhekana nalezi zinselele ngempumelelo, ngokusekelwe ezinkambisweni zemboni:

1. Lungiselela Ukukhetha Kombala
Khetha Izingulube Ezivumelanayo: Khetha izingulube ezihambisana nesisekelo se-polymer (isb., i-PE, i-PP, i-PET) ukuze uqinisekise ukumanzisa nokuhlakazeka okufanele.

Usayizi Wezinhlayiyana Nokwelashwa Okungaphezulu: Sebenzisa izimibalabala ezinosayizi bezinhlayiyana ezincane ukuze uhlakazeke kangcono. Izimibalabala ezilashwe ngaphezulu (isb., ngama-disperants noma ama-coatings) zisiza ukunciphisa ukuhlangana futhi zithuthukise izici zokugeleza.

I-Pigment Loading: Gwema ukweqa umthamo we-pigment onconywayo (imvamisa u-20-40% we-organic pigments, 50-80% we-inorganic). Ukulayisha ngokweqile kungabangela ukuhlangana nokuhlakazeka okubi.

2. Thuthukisa Ukuxuba Nokuhlanganisa
High-Shear Mixing: Sebenzisa ama-twin-screw extruder noma izixube ezishear kakhulu ukuze wephule ama-pigment agglomerate. Lungisa ukucushwa kwesikulufu (isb, amabhlogo okuxova) ukuze uthuthukise ukugunda futhi uthuthukise ukuhlakazeka.

Ukuxuba Ngaphambi Kokuhlanganisa: Hlanganisa ama-pigments nama-dispersants noma ama-resin enkampani yenethiwekhi ngaphambi kokukhipha ukuze uthuthukise ukumanzisa kokuqala futhi unciphise ukunqwabelana.

Ukulawula izinga lokushisa: Gcina izinga lokushisa elilungile lokuncibilika ukuze ugweme ukuwohloka kwe-pigment noma izinkinga ze-viscosity. Ngemibala engezwani nokushisa (isb., izingulube ezithile zemvelo), gcina amazinga okushisa engaphansi komkhawulo wawo wokuwohloka.

3. Sebenzisa ama-Dispersing Agents
Izithasiselo: Faka ama-agent ahlakazayo njengama-wax, ama-stearate, noma ama-polymeric dispersants (isb., i-polyethylene wax, izithasiselo ezisekelwe ku-EVA) ukuze unciphise i-viscosity futhi uthuthukise ukumanzisa kwe-pigment.
Isikali: Ngokuvamile, sebenzisa i-1-5% ye-disperant ngesisindo, kuye ngohlobo lwe-pigment nokulayisha. Ukusebenzisa ngokweqile kungaba nomthelela ongemuhle kwezakhiwo zemishini futhi kungase kubangele ukuqhakaza (inkinga yokubukeka kwendawo).
Inoveli ye-Hyperdispersant ye-Masterbatch: SILIKE SILIMER Series - Izinsiza zokucubungula ezisebenza kahle kakhulu kanye nama-agent ahlakazayo.

SILIKE SILIMER SeriesIzinsiza Zokucubungula kanye Nama-ejenti Ahlakazayoamawax asuselwa ku-silicone esizukulwaneni esilandelayo (aphinde aqanjwe ngokuthi i-Silicone Hyperdispersants) enzelwe ukuletha umbala obala kanye nokuhlakazeka kokugcwalisa ekukhiqizeni i-masterbatch. Ilungele ukugxiliswa kombala, izinhlanganisela ezigcwalisiwe, amapulasitiki obunjiniyela, nezinqubo zokuhlakazeka ezidingekayo. Lawa ma-hyperdispersants athuthukisa ukuzinza kokushisa, i-rheology, kanye nokusebenza kahle kwezindleko kuyilapho esusa izinkinga zokufuduka ezivamile nezithasiselo zendabuko (isb, ama-wax, ama-amide, ama-ester).

4. Lungisa Amapharamitha Wokucubungula

Isivinini sokuScrew: Nyusa isivinini sesikulufu (imvamisa engu-200-500 rpm) ukuze uthuthukise ukugunda nokuhlakazeka. Gwema isivinini esidlulele, njengoba lokhu kungaholela ekulimazeni okushisayo.

Isikhathi Sokuhlala: Lungiselela isikhathi sokuhlala ku-extruder (imvamisa amasekhondi angama-30-60) ukuze uqinisekise ukuxubana okuphelele ngaphandle kokushisisa ngokweqile.

Ukuhlunga: Sebenzisa amaphekhi esikrini (isb, 100-200 mesh) ukuze ususe izinhlayiya ezingahlakazekile futhi uqinisekise ikhwalithi efanayo ye-masterbatch.

5. Bhekana Nezisetshenziswa Nezinkinga Zokulungisa

Izinto Ezisetshenziswayo Ezihlanzekile: Hlanza njalo ama-extruder, izikulufu, futhi ufe ukuze uvimbele ukungcoliswa noma ukunqwabelana kwezinto ezonakele ezithinta ukuhlakazeka.

I-Wear Check: Hlola izikulufu nemiphongolo ukuthi azigugi yini, njengoba okokusebenza okugugile kunciphisa ukusebenza kahle kokugunda futhi kuholela ekuhlakazweni okubi.

Ukunemba Kokudla: Sebenzisa okokuphakelayo kwe-gravimetric ukuthola umbala oqondile kanye nokuthakwa kwe-resin, uqinisekisa ukuvumelana ekuhlakazweni kwe-pigment.
