Ndi mitundu ingati ya Hydroxypropyl methylcellulose (HPMC)?

Hydroxypropyl methylcellulose (HPMC) imagawidwa mumtundu wanthawi yomweyo komanso mtundu wosungunuka.

Nthawi yomweyoHydroxypropyl methylcellulose (HPMC)amabalalika mofulumira m'madzi ozizira ndipo amasowa m'madzi. Panthawi imeneyi, madzi alibe mamasukidwe akayendedwe, chifukwa HPMC kokha omwazika m'madzi ndipo si kwenikweni kupasuka. Pafupifupi mphindi 2, kukhuthala kwamadzimadzi kumawonjezeka pang'onopang'ono, ndikupanga mawonekedwe a viscous colloid.

Hot-melt Hydroxypropyl methylcellulose (HPMC), zikasonkhana m'madzi ozizira, zimatha kumwazikana m'madzi otentha ndikuzimiririka m'madzi otentha. Kutentha kumatsika mpaka kutentha kwina (chinthu cha Shijiazhuang Lvyuan Cellulose Co., Ltd. ndi madigiri 60 Celsius), kukhuthala kumawonekera pang'onopang'ono mpaka Kupangidwa kwa viscous colloid yowonekera.

Hot-melt Hydroxypropyl methylcellulose (HPMC) nthawi zambiri amagwiritsidwa ntchito mu putty powder ndi matope. Njira yosakaniza ufa imatengedwa: ufa wa HPMC umasakanizidwa ndi zinthu zina zambiri za ufa, zosakaniza bwino ndi chosakaniza, kenako zimasungunuka ndi kuwonjezera madzi, ndiye HPMC ikhoza kusungunuka popanda clumping Cohesion, chifukwa ngodya iliyonse yaying'ono imakhala ndi zokhazokha. ufa wochepa wa HPMC, womwe udzasungunuka mwamsanga ukakumana ndi madzi.

Instant Hydroxypropyl methylcellulose (HPMC) ili ndi ntchito zosiyanasiyana. Kuphatikiza pa putty powder ndi matope, amagwiritsidwa ntchito kwambiri pazinthu zatsiku ndi tsiku monga guluu wamadzimadzi, utoto, ndi zotsukira.
