Hydroxypropyl Methyl Cellulose (HPMC) Yogwiritsidwa Ntchito Kupaka Pamadzi

Ntchito yathu yosungira madzi ya cellulose ether popaka latex, makamaka kupaka kwa PVA kwapamwamba kumapereka ntchito yabwino kwambiri yopaka, kuyanika kwa zamkati wandiweyani, sikungapangitse flocculation; Kuchulukitsa kwake kumatha kuchepetsa mlingo, kupititsa patsogolo chuma cha kapangidwe kake, ndikuwongolera kuyimitsidwa kwa makina opaka. Zabwino kwambiri rheological katundu ❖ kuyanika, akhoza kukhala malo amodzi, kusunga yabwino thickening boma ❖ kuyanika; M'malo otayidwa, okhala ndi madzi abwino kwambiri, ndipo sangawaza; Mu ❖ kuyanika ndi wodzigudubuza ❖ kuyanika, zosavuta kufalitsa mu gawo lapansi, yomanga yabwino; Chophimbacho chikatha, kukhuthala kwa dongosololi kudzachira nthawi yomweyo, kuphimba kumatulutsa kutuluka.

M'dziko losangalatsa kwambiri la utoto wa latex wamadzi, chowonjezera chimodzi chofunikira kwambiri ndi Hydroxy Propyl Methyl Cellulose.(HPMC). Kupatula kukhala thickener kwambiri imayenera, mtundu wa zowonjezera amaperekanso khamu la zinthu zina zothandiza, monga burashi-luso, sag kukana, emulsification, kuyimitsidwa mphamvu, etc, pamene kupereka zabwino kwambiri ngakhale mtundu,komansokupanga mtundu uwu wa thickener wotchuka kwambiri ndi opanga utoto ambiri padziko lapansi.

Amagwiritsidwa ntchito mu utoto wamadzi. Imawonetsa zotsatira zake zabwino kwambiri za thickening,ndirheological katundu, kubalalitsidwa ndi solubility. Ili ndi kukhazikika bwino kwachilengedwe, imapereka nthawi yokwanira yogulitsira utoto. Kuteteza bwino ma pigment ndi filler sedimentation.
