Zotsatira za Kugwiritsa Ntchito Molakwika Hydroxypropyl Methyl Cellulose

Ponena za njira yogwiritsira ntchito akatswiri yotengedwa ndi mankhwala, ndikofunikira kukopa chidwi ndi chidwi cha aliyense wogwira ntchito, chifukwa ichi ndiye chinsinsi chopanga zisankho zogwira mtima komanso kumaliza bwino ntchito iliyonse yomanga.Ngati njira yopangira izi ingakhudze kwambiri kugwiritsa ntchito bwino kwa mankhwalawa, mwachitsanzo, hydroxypropyl methylcellulose, yomwe imadziwika kwambiri m'magawo osiyanasiyana, tiyeni tiwone pamodzi pansipa.

Kusungidwa kwa madzi kwa methylcellulose kumadalira kuchuluka kwake, kukhuthala, kukongola kwa tinthu ndi kusungunuka kwake.Nthawi zambiri, ngati kuchuluka kwake kuli kwakukulu, fineness ndi yaying'ono, ndipo mamasukidwe ake ndiakuluakulu, kuchuluka kwa kusunga madzi kumakhala kwakukulu.Pakati pawo, kuchuluka kwa kuwonjezera kumakhudza kwambiri kuchuluka kwa kusungirako madzi, ndipo msinkhu wa viscosity suli wofanana mwachindunji ndi mlingo wa kusunga madzi.The Kusungunuka mlingo makamaka zimadalira mlingo wa padziko kusinthidwa kwa mapadi particles ndi tinthu fineness.Pakati pa ma cellulose ethers omwe ali pamwambawa, methyl cellulose ndi hydroxypropyl methyl cellulose ali ndi milingo yayikulu yosungira madzi.

Methylcellulose imasungunuka m'madzi ozizira, ndipo zimakhala zovuta kusungunuka m'madzi otentha.Njira yake yamadzimadzi imakhala yokhazikika pa pH = 3 ~ 12.Iwo ali ngakhale zabwino ndi wowuma, guar chingamu, etc. ndi surfactants ambiri.Pamene kutentha kufika kutentha kwa gelation, gelation imachitika.

Pankhani ya kagwiritsidwe koyenera ka hydroxypropyl methylcellulose tidakudziwitsani pamwambapa, ndikofunikira kukopa chidwi ndi chidwi cha wogwiritsa ntchito aliyense, kuti muwonetsetse kuti mankhwalawa ndi othandiza.
