Mafotokozedwe Akatundu:
Hydroxyethyl cellulose (HEC) ndi ufa woyera kapena wopepuka wachikasu, wopanda fungo, wopanda poizoni. Amapangidwa kuchokera ku cellulose yoyambira ndi ethylene oxide (kapena chloroethane) ndi etherification. Ndi non-ionic soluble cellulose ether. Chifukwa HEC mapadi ali ndi makhalidwe abwino a thickening, kuyimitsidwa, kubalalitsidwa, emulsification, adhesion, filimu mapangidwe, kuteteza chinyezi, ndi kuteteza colloids, chimagwiritsidwa ntchito mafuta m'zigawo, zokutira, zomangamanga, mankhwala ndi chakudya, nsalu, papermaking, ndi minda ina.
Ntchito:
1. Hydroxyethyl cellulose ufa ukhoza kusungunuka m'madzi otentha ndi ozizira, ndipo sudzathamanga pamene watenthedwa kapena wophika. Chifukwa chake, ili ndi mawonekedwe osiyanasiyana a solubility ndi mamasukidwe akayendedwe komanso osagwirizana ndi thermogelability.
2. HEC imatha kukhala limodzi ndi ma polima osungunuka m'madzi, ma surfactants, ndi mchere. HEC ndiyabwino kwambiri colloidal thickener yokhala ndi mayankho a dielectric apamwamba kwambiri.
3. Mphamvu yake yosungira madzi imakhala yowirikiza kawiri kuposa ya methylcellulose, ndipo imakhala ndi malamulo oyendetsera bwino.
4. Poyerekeza ndi methylcellulose ndi hydroxypropylmethylcellulose, HEC ili ndi mphamvu zoteteza kwambiri za colloid.
Makampani Omanga: HEC itha kugwiritsidwa ntchito ngati chosungira chinyezi komanso choletsa simenti.
Makampani Obowola Mafuta: Atha kugwiritsidwa ntchito ngati chowonjezera komanso chopangira simenti pamadzi opangira mafuta. Madzi obowola ndi HEC amatha kuwongolera bwino pobowola kutengera ntchito yake yotsika yolimba.
Makampani Opaka: HEC imatha kutenga nawo gawo pakukulitsa, kutulutsa, kubalalitsa, kukhazikika komanso kusunga madzi pazinthu za latex. Amadziwika ndi kukhuthala kwakukulu, kufalikira kwamtundu wabwino, kupanga mafilimu, komanso kukhazikika kosungirako.
Pepala ndi Inki: Itha kugwiritsidwa ntchito ngati chowerengera pamapepala ndi pamapepala, ngati chowonjezera komanso kuyimitsa inki zotengera madzi.
Daily Chemicals: HEC ndiyopanga bwino kupanga mafilimu, zomatira, zokhuthala, zokhazikika komanso zosokoneza mu shampoo, zowongolera tsitsi, ndi zodzoladzola.
Phukusi: 25 kgs / thumba kapena momwe mukufunira.
Kusungirako: Sungani pamalo opumira mpweya, owuma.
Miyezo yoperekedwa: International Standards.
