Kodi ntchito ya hydroxypypyl ndi chiyani methylcellulose?

Hydroxypropyll methylcellulose (hpmc) ndi ufa woyera, wopanda fungo, wosasangalatsa, womwe umasungunuka m'madzi ozizira kuti apange njira yosinthira ma viscous.

Hydroxypropyl methylcellulose ali ndi ntchito zamphamvu, kugwirizanitsa, kubalalika, mawonekedwe a filimu, zodzitchinjiriza, kutetezedwa kwa mawonekedwe.

Hydroxypypyl amagwiritsidwa ntchito kwambiri pomanga zida zomangira, zokutira, matekenti, zamankhwala, zamagetsi, zodzola, zodzoladzola komanso mafakitale ena. Malinga ndi kugwiritsa ntchito, hpmc imatha kugawidwa: kumanga osanjikiza, chakudya chosanjikiza, mankhwala opangira mankhwala. Pakadali pano, ntchito zambiri zapakhomo ndi kalasi yomanga, ndipo kuchuluka kwa ufa womangawu ndi waukulu, pafupifupi 90% amagwiritsidwa ntchito popanga ufa, ndipo enawo amagwiritsidwa ntchito popanga matope a simenti ndi binder.

Cellulose ether ndi polymer polymer yopanga ndi soleble ndi solvents yosungunuka.

Mu minda yosiyanasiyana ya mafakitale, monga zida zomangira zamankhwala, etc., imagwira ntchito yosiyana, yosungirako madzi, Thiccener, kupanga, kupanga mafilimu, komanso zomata.

Pakati pawo, makampani ogulitsa a polyvinyl ndi a emulsifiers ndi omwazika, ndipo makampani opanga mankhwala ndi a commers ndi odekha ndikuwongolera zida zamagetsi. Chifukwa ma cellulose ali ndi ntchito zosiyanasiyana mu polyvinyl clorviry, imakhala ndi njira inayake kwambiri.
