Ma cellulose ether HE mndandanda, ndiye kuti, hydroxyethyl cellulose, ndi ufa woyera mpaka wa mkaka. Ikhoza kusungunuka m'madzi otentha ndi madzi ozizira, koma sikophweka kusungunuka mu zosungunulira za organic. Jinshi mtundu mapadi efa HE mndandanda mankhwala ndi amphamvu posungira madzi, filimu kupanga, kukana mchere ndi thickening zotsatira. Ilinso ndi mawonekedwe abwino kwambiri amtundu ndipo ndi chowonjezera chabwino pamapulogalamu a latex.

Hydroxyethyl cellulose HEC ndi chokhuthala chomwe chimagwiritsidwa ntchito kwambiri popaka utoto ndipo chimakhala ndi izi:

(1) Kusinthasintha kwamphamvu kwa Hydroxyethyl cellulose HEC ndi polima yosungunuka m'madzi yopanda ionic yomwe ingagwiritsidwe ntchito pa pH (2-12). Ikhoza kusakanikirana ndi zigawo zikuluzikulu mu zokutira zonse (monga inki, zowonjezera, mchere wosungunuka ndi electrolytes) popanda zochitika zachilendo. ndi

(2) Kumanga bwino. The ❖ kuyanika ndi hydroxyethyl mapadi HEC ali pseudoplasticity, kotero angagwiritsidwe ntchito ndi burashi, kupopera mbewu mankhwalawa, wokutira wodzigudubuza ndi njira zina zomangamanga. Ubwino, kusanja ndikwabwinoko. ndi

(3) Palibe zotsatira zoipa pa filimu yokutira. Chifukwa cha mawonekedwe osawoneka bwino azovuta zamadzi amtundu wa HEC wamadzimadzi, sikophweka kutulutsa thovu pakumanga ndi kupanga, ndipo pali chizolowezi chochepa chopanga mabowo amapiri ndi mapini. ndi

(4) Kukula kwamtundu wabwino. Hydroxyethyl cellulose HEC ili ndi miscibility yabwino kwambiri yokhala ndi zomangira zambiri ndi utoto, kotero kuti utoto wokonzedwayo ukhale wokhazikika komanso wosasinthasintha.

(5) Kukhazikika bwino kosungirako. Pakusungidwa kwa utoto, imatha kusungitsa kuyimitsidwa ndi kufalikira kwa pigment, popanda zovuta zoyandama komanso kuphuka. Pamwamba pa utoto pali wosanjikiza madzi ochepa. Pamene kutentha kosungirako kumasintha, kukhuthala kwake kumakhalabe komweko. wokhazikika.
