Titanium Dioxide ya Masterbatch

Titanium dioxide ya masterbatches ndi chowonjezera chosunthika, chapamwamba kwambiri chopangidwa kuti chikwaniritse kuwala ndi kuyera muzinthu zapulasitiki. Chogulitsacho chimadziwika ndi kuyamwa kwamafuta ochepa, kumagwirizana bwino ndi ma resin apulasitiki, kubalalitsidwa mwachangu komanso kwathunthu.

Zili ndi kuwala kwakukulu komanso zoyera kuti zitsimikizire kuti mtundu womwe ukufunidwa umatheka mosavuta. Ma pigment omwe ali mu mankhwalawa ndi owala bwino komanso omwazika mofanana kuti apeze zotsatira zabwino kwambiri za utoto. Amapereka kugawa kwamtundu wofanana, kuthetsa mikwingwirima kapena kusagwirizana panthawi yopanga. Kuyera komwe kumapezeka ndi mankhwalawa ndikoyenera kuzinthu zosiyanasiyana kuphatikizapo filimu extrusion, jekeseni akamaumba ndi kuwomba akamaumba.

Chimodzi mwazinthu zodziwika bwino za mankhwalawa ndikuchepetsa kwake kwamafuta. Khalidweli limatsimikizira kuti masterbatch imasunga mtundu wake wowoneka bwino komanso mawonekedwe ake ngakhale pazodzaza kwambiri. Mayamwidwe otsika amafuta amawonjezera kukana kwa UV, komwe kumawonjezera kulimba komanso moyo wautali wazinthu zomaliza. Kuphatikiza apo, izi zimachepetsa kuchuluka kwa ma masterbatches ofunikira, kupulumutsa ndalama zopangira.

Kugwirizana kwabwino kwa titaniyamu woipa wa masterbatch okhala ndi ma resin osiyanasiyana apulasitiki kumapangitsa kukhala chisankho chabwino kwa opanga pulasitiki. Itha kuphatikizidwa mosavuta mumitundu yosiyanasiyana ya ma polima, kuphatikiza polyethylene, polypropylene, ndi polystyrene, pakati pa ena. Kugwirizana kwake kumatsimikizira kufalikira kwabwino ndi kusakaniza, zomwe zimapangitsa kuti pakhale njira yopangira bwino komanso yowonjezereka. Oyenera kwa namwali komanso zobwezerezedwanso pulasitiki resins, mankhwala ndi zosunthika ndi zisathe.

Pankhani ya processing, masterbatches ndi titaniyamu woipa kupereka mofulumira ndi wathunthu kubalalitsidwa. Izi zikutanthauza kuti zitha kumwazikana mosavuta ndikuphatikizidwa muzitsulo zapulasitiki popanda kuphatikizika kapena kugawa kosafanana. Kuchuluka kwa dispersibility kumatsimikizira kuti mtundu wofunidwa ndi opacity zimatheka mofanana mu mankhwala onse, kupititsa patsogolo kukongola kwake. Komanso, mankhwala mofulumira dispersibility amachepetsa processing nthawi, kuthandiza kuonjezera zokolola ndi bwino kupanga.

Mwachidule, mankhwalawa ndi chowonjezera chabwino kwambiri, chomwe chimaphatikiza kuwala kwakukulu, kuyera, kuyamwa kwamafuta ochepa, kumagwirizana kwambiri ndi utomoni wapulasitiki komanso kubalalitsidwa mwachangu. Kuchita kwake kwapadera kumapangitsa kukhala chisankho chabwino kwambiri kwa mafakitale osiyanasiyana omwe akufuna kupititsa patsogolo mtundu, kukongola ndi magwiridwe antchito apulasitiki. Ndi titaniyamu yathu ya titaniyamu ya masterbatches, mutha kukwaniritsa kulimba kwamtundu, kulimba komanso magwiridwe antchito omwe muyenera kukwaniritsa zomwe makasitomala amafuna ndikusunga utsogoleri wamsika.
