Hydroxyethyl cellulose (HEC) ndi hydroxypropyl methyl cellulose (HPMC) ndi awiri omwe amagwiritsidwa ntchito kwambiri.Ndi zigawo za zomatira zotanuka zomwe zingagwiritsidwe ntchito kupereka kukana, kukulitsa kukhuthala, kapena kupereka ductility.Mapangidwe awo a mankhwala ndi ofanana, koma pali kusiyana koonekeratu.
HEC ndi analogue ya ethylene-acetate yomwe imakhala ndi formaldehyde, methanol ndi sodium hydroxide.Ndi thixotropic kwambiri ndipo angagwiritsidwe ntchito ngati lubricant, pamwamba mankhwala wothandizira ndi zomatira kwa magetsi ndi mafakitale zipangizo.Ma hec amathanso kugwiritsidwa ntchito ngati thickeners, dispersants ndi scale inhibitors.
HPMC ndi ena ethylene-acetate analogue, wopangidwa makamaka methanol, sodium hydroxide, ndi carbonate.Ili ndi mamasukidwe apamwamba, elasticity ndi kufalikira, imatha kugwiritsidwa ntchito ngati zomatira, utoto, zotsukira ndi zowonjezera za inki.Kuphatikiza apo, itha kugwiritsidwanso ntchito pokonzekera kristalo ndipo imakhala ndi kukhazikika kwadongosolo losalala.
Hydroxyethyl cellulose HEC, monga siionic surfactant, ili ndi zinthu zotsatirazi kuwonjezera pa thickening, kuyimitsidwa, adhesion, kuyandama, filimu mapangidwe, kubalalitsidwa, kusunga madzi ndi zoteteza colloidal zotsatira:
1, hydroxyethyl cellulose HEC ikhoza kusungunuka m'madzi otentha kapena ozizira, kutentha kwakukulu kapena kuwira sikudutsa, kotero kuti ili ndi mitundu yambiri ya kusungunuka ndi kukhuthala kwamakamaka, ndi katundu wa gel osatentha;
2, hydroxyethyl mapadi HEC lokha sanali ionic mtundu akhoza kukhala limodzi ndi osiyanasiyana ma polima ena sungunuka madzi, surfactants, mchere, ndi mtundu wa colloidal thickener munali mkulu electrolyte njira;
3, hydroxyethyl cellulose HEC mphamvu yosungira madzi ndipamwamba kawiri kuposa methyl cellulose, ndi kayendedwe ka kayendedwe;
4. Kutha kwa kubalalitsidwa kwa hydroxyethyl cellulose HEC ndi koyipa poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, koma chitetezo cha colloid ndi cholimba.
Cholinga: Nthawi zambiri amagwiritsidwa ntchito ngati thickening wothandizira, zoteteza, zomatira, stabilizer ndi kukonza utoto wa latex, lacquer, inki.Zowonjezera zomwe zimagwiritsidwa ntchito pobowola mafuta, ma gels, mafuta odzola, mafuta odzola, oyeretsa maso, ma suppositories ndi mapiritsi, amagwiritsidwanso ntchito ngati ma gels a hydrophilic, zida za mafupa, kukonzekera kwa mafupa okonzekera kumasulidwa, ndipo angagwiritsidwe ntchito ngati zolimbitsa thupi.
