Pigment Wobalalitsidwa ndi Pigment Imodzi

Ndi chitukuko mosalekeza makampani, masiku ano pulasitiki mitundu processing ndi akamaumba akupita ku zizolowezi zazikulu zida, kupanga kwambiri makina, ntchito mkulu-liwiro, kukonzanso mosalekeza ndi standardization wa mankhwala. Izi zidapangitsa kuti pakhale zinthu zambiri zowoneka bwino kwambiri, zoonda kwambiri komanso zazing'ono kwambiri, zomwe zimafuna kufalikira kwamtundu wapamwamba. Kuphatikiza apo, zofunikila zakuchita bwino kwambiri, kuteteza chilengedwe, kupulumutsa mphamvu ndi kuchepetsa mtengo zikuchulukiranso. Chifukwa zida zonse zomangira pulasitiki (monga: makina opangira jakisoni, makina opota kapena wononga wononga, ndi zina zotero) sizingapereke mphamvu yakumeta ubweya wofunikira pakubalalitsa kwa pigment panthawi yokonza, ntchito yobalalika ya pigment nthawi zambiri imapangidwa ndi akatswiri opanga pigment. kapena opanga mtundu masterbatch.

Pre-omwazikana pigment(Yomwe imadziwikanso kuti Pigment Preparation kapena SPC-Single Pigment Concentration) ndi kuchuluka kwa pigment imodzi. Malinga ndi mawonekedwe a mitundu yosiyanasiyana ya pigment, pigment yomwe imabalalika kale imakhala ndi 40-60% ya pigment (zomwe zili ndi pigment yomwe imabalalitsidwa kale ndi kampani yathu imatha kufika 80-90%), ndikukonzedwa ndi wapadera. ndondomeko pogwiritsa ntchito zipangizo zapadera. Njira zobalalitsira zogwira mtima komanso kuwongolera kosamalitsa kumapangitsa kuti inki yomwe ilimo iwonetse mawonekedwe abwino kwambiri a tinthu kuti tikwaniritse mawonekedwe abwino kwambiri amtundu. Maonekedwe a pigment pre-omwazika akhoza kukhala zabwino pow particles ndi kukula za 0. 2-0.3mm, ndipo mankhwala akhoza kupangidwanso mu tinthu ndi kukula wamba.mitundu masterbatches. Ndi chifukwa chakuti pigment yobalalika isanakwane imakhala ndi mikhalidwe yoonekeratu yomwe imagwiritsidwa ntchito kwambiri popanga ma masterbatches amtundu.

Thepre-omwazikana pigmentili ndi zabwino zotsatirazi

• Popeza pigment imabalalika kwathunthu, imakhala ndi mphamvu yamtundu wapamwamba. Poyerekeza ndi kugwiritsa ntchito inki ya ufa, mphamvu yamtundu imatha kusintha ndi 5-15%.

• Njira zosakanikirana zimafuna mphamvu zochepa zosakanikirana za kumeta ubweya kuti zikwaniritse zotsatira zomwe mukufuna. Mwachitsanzo, zinthu zapamwamba za masterbatch zimatha kupangidwa ndi zida zosavuta (monga screw imodzi). Sinthani ku mitundu yonse ya zida za extrusion, khalidwe lokhazikika, ndondomeko yosinthika yopanga.

• Pigment yobalalika kale imagwira ntchito kuti ikwaniritse bwino mtundu: kuwala kwamtundu, kuwonekera, gloss, ndi zina.

• Kuthetsa fumbi lowuluka popanga, kukonza malo ogwirira ntchito komanso kuchepetsa kuipitsa.

• Palibe fouling zida, imathandizira kuyeretsa zida pakusintha mtundu.

• Fine ndi yunifolomu pigment particles akhoza kutalikitsa moyo utumiki wa fyuluta chophimba, kuchepetsa m'malo nthawi ya fyuluta chophimba ndi kukonza bwino kupanga.

• Maonekedwe a mankhwalawa ndi yunifolomu popanda kumangirirana, komwe kuli koyenera kwa mitundu yosiyanasiyana ya feeder; njira yotumizira siili pamlatho kapena kutsekedwa.

• Kumathetsa kufunika kobalalitsa inki ndikuwonjezera kwambiri mphamvu ya malo opangira masterbatch omwe alipo.

• Itha kugwiritsidwa ntchito limodzi ndi mitundu ina, yogwira ntchito mwamphamvu.

• Mitundu yosiyanasiyana ya mlingo, yoyenera mitundu yosiyanasiyana ya utomoni wonyamulira, ntchito yabwino yosakaniza.
