Kev Siv Tshuaj Txhua Hnub Qib Hydroxypropyl Methyl Cellulose (HPMC) hauv Kev Ntxuav

Cov tshuaj txhua hnub qib hydroxypropyl methylcellulose yog cov khoom siv hluavtaws ua los ntawm ntuj cellulose los ntawm kev hloov kho tshuaj. Cellulose ether yog derivative ntawm natural cellulose. Kev tsim cov cellulose ether yog txawv los ntawm hluavtaws polymers. Nws cov khoom siv yooj yim tshaj plaws yog cellulose, lub ntuj polymer compound. Vim qhov tshwj xeeb ntawm cov qauv cellulose, cellulose nws tus kheej tsis muaj peev xwm ua rau cov tshuaj etherification. Txawm li cas los xij, tom qab kev kho mob ntawm tus neeg mob o, lub zog hydrogen bonds ntawm cov saw hlau molecular thiab cov chains raug rhuav tshem, thiab cov active tso tawm ntawm pawg hydroxyl los ua reactive alkali cellulose. Tau txais cellulose ether.

200,000 viscosity instant hydroxypropyl methylcellulose rau qib tshuaj txhua hnub yog cov hmoov dawb los yog daj me ntsis, tsis muaj ntxhiab, tsis qab thiab tsis muaj tshuaj lom. Nws tuaj yeem yaj hauv dej txias thiab sib xyaw hnyav ntawm cov organic teeb meem los tsim cov kua nplaum pob tshab. Cov dej ua kua muaj qhov ua haujlwm saum npoo av, siab pob tshab, muaj zog ruaj khov, thiab tsis cuam tshuam los ntawm pH thaum yaj hauv dej. Nws muaj cov nyhuv thickening thiab antifreeze nyob rau hauv cov tshuaj zawv plaub hau thiab cov gels da dej, thiab muaj cov dej tuav thiab cov yeeb yaj kiab zoo rau cov plaub hau thiab tawv nqaij. Nrog rau kev nce siab ntawm cov khoom siv raw, kev siv cellulose (antifreeze thickener) hauv tshuaj zawv plaub hau thiab da dej gel tuaj yeem txo tus nqi thiab ua tiav cov txiaj ntsig xav tau.

Nta thiab qhov zoo ntawm txhua hnub tshuaj qib cellulose HPMC:

1. Tsawg khaus, kub thiab tsis muaj tshuaj lom;

2. Cov nqi pH dav ruaj khov, uas tuaj yeem ua kom nws ruaj khov hauv thaj tsam ntawm pH tus nqi 3-11;

3. Txhim kho qhov txias;

4. Ua npuas ncauj, ruaj khov ua npuas ncauj, txhim kho daim tawv nqaij;

5. Txhim kho qhov fluidity ntawm qhov system zoo.

Cov Scope ntawm daim ntawv thov ntawm cov tshuaj txhua hnub qib cellulose HPMC:

Siv hauv tshuaj zawv plaub hau, ntxuav lub cev, tshuaj ntxuav lub ntsej muag, tshuaj pleev ib ce, cream, gel, toner, plaub hau txias, styling khoom, tshuaj txhuam hniav, qaub ncaug, khoom ua si npuas dej.

Lub luag haujlwm ntawm txhua hnub tshuaj qib cellulose HPMC

Nyob rau hauv daim ntawv thov kom zoo nkauj, nws yog tsuas yog siv rau thickening, foaming, ruaj khov emulsification, dispersion, adhesion, txhim kho zaj duab xis-tsim thiab dej tuav cov khoom ntawm cov tshuaj pleev ib ce, high-viscosity khoom yog siv rau thickening, low-viscosity khoom yog tsuas yog siv rau ncua kev kawm ntawv. dispersion thiab film forming

Txhua hnub tshuaj qib cellulose HPMC tshuab:

Lub viscosity ntawm hydroxypropyl methylcellulose haum rau kev lag luam tshuaj txhua hnub yog 100,000, 150,000, thiab 200,000. Raws li koj tus kheej cov qauv, qhov sib ntxiv ntawm cov khoom yog feem ntau 3 txog 5/1000
