Monga surfactant yopanda ionic,hydroxyethyl cellulose(HEC) ili ndi zinthu zotsatirazi kuphatikiza kukhuthala, kuyimitsa, kumanga, kuyandama, kupanga mafilimu, kubalalitsa, kusunga madzi komanso kupereka ma colloids oteteza:
1. HEC imasungunuka m'madzi otentha kapena ozizira, ndipo sichitha kutentha kwambiri kapena kutentha, choncho imakhala ndi mitundu yambiri ya solubility ndi viscosity, ndi gelation yopanda kutentha;
2. The sanali ionic palokha akhoza kukhala limodzi ndi ma polima ena sungunuka madzi, surfactants ndi mchere osiyanasiyana, ndipo ndi wabwino kwambiri colloidal thickener okhala mkulu-concentration electrolyte njira;
3. Mphamvu yosungira madzi imakhala yowirikiza kawiri kuposa ya methyl cellulose, ndipo imakhala ndi malamulo oyendetsera bwino.
4. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, mphamvu yobalalika ya HEC ndiyoipa kwambiri, koma mphamvu yoteteza colloid ndiyo yamphamvu kwambiri.
Momwe mungagwiritsire ntchito hydroxyethyl cellulose?
1. Lowani mwachindunji kupanga
1. Onjezerani madzi oyera ku chidebe chachikulu chokhala ndi makina opangira ubweya wambiri.
2. Yambani kuyambitsa mosalekeza pa liwiro lotsika ndikusefa pang'onopang'ono cellulose ya hydroxyethyl mu yankho mofanana.
3. Pitirizani kuyambitsa mpaka tinthu tating'onoting'ono tanyowa.
4. Kenaka yonjezerani wothandizira mphezi, zowonjezera zamchere monga ma pigment, zofalitsa zothandizira, madzi a ammonia.
5. Limbikitsani mpaka cellulose yonse ya hydroxyethyl itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri) musanawonjezere zigawo zina mu fomula, ndikupera mpaka zitakhala.
