Cov tshuaj txhua hnub qib hydroxypropyl methylcellulose yog ib qho hluavtaws polymer ua los ntawm ntuj cellulose paj rwb linters los ntawm kev hloov kho etherification.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.
Cov tshuaj txhua hnub qib hydroxypropyl methylcellulose yog cov hmoov dawb los yog daj me ntsis, thiab nws tsis muaj ntxhiab, tsis qab thiab tsis muaj tshuaj lom.Ib qho hnyav uas tuaj yeem tawg sai sai hauv dej txias thiab sib xyaw nrog cov organic teeb meem, thiab ncav cuag qhov siab tshaj plaws nyob rau hauv ob peb feeb 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 thickening thiab antifreeze teebmeem 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, cellulose (antifreeze thickener) siv rau hauv cov tshuaj ntxhua khaub ncaws, tshuaj zawv plaub hau, da dej gel tuaj yeem txo tus nqi thiab ua tiav cov txiaj ntsig xav tau.
Nta thiab qhov zoo ntawm cov tshuaj txhua hnub qib dej txias instant 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.
6. Yooj yim rau siv, muab tso rau hauv dej txias kom sai sai tsis muaj clumping
Cov Scope ntawm daim ntawv thov ntawm cov tshuaj txhua hnub qib cellulose HPMC:
Siv rau hauv cov tshuaj ntxhua khaub ncaws, tshuaj zawv plaub hau, tshuaj ntxuav lub cev, tshuaj ntxuav lub ntsej muag, tshuaj pleev ib ce, gel, toner, txias, cov khoom siv kho kom zoo nkauj, tshuaj txhuam hniav, tshuaj ntxuav qhov ncauj, cov 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 methyl fiber ntau haum rau kev lag luam tshuaj txhua hnub yog 100,000, 150,000, thiab 200,000.Feem ntau, siab viscosity feem ntau yog siv, thiab cov nyhuv thickening yog qhov zoo tshaj plaws.Raws li koj tus kheej cov qauv, qhov sib ntxiv ntawm cov khoom yog feem ntau 1,000.2 qhov chaw mus rau 4 qhov chaw ntawm ib txhiab.
Cov kev ceev faj
Cov tshuaj tsis muaj txiaj ntsig niaj hnub tsis tsim nyog qib hydroxypropyl methylcellulose nthuav tawm cov pob tshab tsis zoo, cov nyhuv thickening tsis zoo, thinning tom qab khaws cia ntev, thiab qee qhov chaw tseem tuaj yeem ua pwm.Txhawm rau kom tsis txhob muaj cellulose nag lossis daus thaum siv, nws yuav tsum tau nplawm ua ntej qhov sib xws.siv.
