HPMC, yomwe imadziwikanso kuti hydroxypropyl methylcellulose, ndi gulu la banja la ma cellulose ethers. Amachokera ku cellulose, polima yachilengedwe yomwe imapezeka m'makoma a cellulose. HPMC chimagwiritsidwa ntchito makampani zomangamanga chifukwa katundu multifunctional.
HPMC imagwiritsidwa ntchito ngati chowunitsa, chomangira, chopangira filimu komanso chosungira madzi muzinthu zomangira monga zopangira simenti, zomatira matailosi, pulasitala, pulasitala ndi ma grouts. Kapangidwe kake kamankhwala kamalola kuti amwe madzi ndikupanga chinthu chonga gel chomwe chimapangitsa kuti zinthu zisamagwire ntchito, kumamatira komanso kulimba kwa zida zomangira.
Nazi zina mwazinthu zazikulu ndikugwiritsa ntchito kwa HPMC pantchito yomanga:
Kusunga madzi: HPMC imayamwa ndikusunga madzi, kuletsa zida za simenti kuti ziume mwachangu. Izi zimathandizira kuchepetsa kusweka, kumapangitsa kuti madzi aziyenda bwino komanso kumapangitsanso mphamvu zonse komanso kulimba kwa zinthu zomanga.
Kupititsa patsogolo kachulukidwe: HPMC imagwira ntchito ngati rheology modifier, yomwe imapereka kusinthika kwabwinoko komanso kugwiritsa ntchito kosavuta kwa zida zomangira. Imakulitsa kufalikira ndi kukana kugwa kwa matope ndi ma pulasitala, kuwapangitsa kukhala osavuta kunyamula ndikuyika.
Kulumikizana ndi mgwirizano: HPMC imathandizira kumamatira pakati pa zida zosiyanasiyana zomangira. Zimawonjezera mphamvu zomangira zomatira, zomatira ndi zomata, kuonetsetsa kuti zimamatira bwino ku magawo monga konkire, matabwa ndi matailosi.
Kukaniza kwa Sag: HPMC imachepetsa kugwa kapena kugwa kwa zinthu zoyima monga zomatira matailosi kapena pulayimale pakugwiritsa ntchito. Izi zimathandiza kusunga makulidwe omwe mukufuna ndikupewa kugwa kapena kudontha.
Kupanga Mafilimu: HPMC ikauma, imapanga filimu yopyapyala, yosinthika, yowonekera. Kanemayu atha kupereka kukana kwamadzi bwino, kukana kwanyengo komanso chitetezo chapamwamba pazogwiritsa ntchito zomangira.
