Ob peb hnub dhau los no, qee cov neeg tau teeb meem los ntawm cov kua xab npum tuab. Qhov tseeb, ua kom ncaj ncees, Kuv tsis tshua muaj cov kua xab npum tuab, tab sis kuv kuj tau hais tias muaj ntau txoj hauv kev kom ua tiav. raws li ib qho ntawm cov kev xaiv.
yam ntxwv:
HECHydroxyethylcellulosetseem hu ua siab molecular cellulose (los yog siab molecular polymer)
Cov khoom siv raw yog ua los ntawm cov nroj tsuag fiber ntau hloov kho, uas muaj kev xav zoo heev! Tab sis ua ncaj ncees, kuv tus kheej tsis nyiam nws.
Nws yog cov hmoov dawb (daj) hmoov, uas tsis yog-ionic dej-soluble polymer compound, uas tuaj yeem siv los ua cov thickener thiab suspending agent.
Nws yog qhov yooj yim rau kev khiav dej num hauv dej kub dua li dej txias, nws yuav tsum tau muab khaws cia, thiab PH tus nqi khaws cia siab tshaj 6 thiab nws yooj yim dua rau yaj.
Feem ntau siv nyob rau hauv ntau yam kev zoo nkauj thiab tu cov khoom, nws muaj ib tug kov zoo li hyaluronic acid, cov khoom tiav yog pob tshab, thiab cov kua qaub kuj yog siab tshaj.
Ua kua xab npum Thickening:
Siv 1-2% concentration, ntxiv 1 g ntawmHydroxyethylcellulosemus rau 99 g ntawm distilled dej thiab do, thov do txhua 5-10 feeb thaum tos, tsis txhob cia cov hmoov cov ntaub ntawv nyob rau hauv, kom txog rau thaum lub gel yog pob tshab, ces ntxiv do nyob rau hauv kua xab npum.
Kev siv tshuaj pleev ib ce:
1. Hydroxyethylcellulose tuaj yeem siv los ua pob tshab colloids, uas feem ntau yog siv los tsim cov khoom lag luam qib siab, gels, daim npog ntsej muag, thiab tshuaj zawv plaub hau.
2. Nws tuaj yeem siv tau los ua tus neeg sawv cev ncua thiab thickening rau cov khoom qab zib los kho qhov zoo thiab sib xws ntawm cov khoom qab zib.
Cov lus qhia rau kev siv:
1. Cov dej kub yog yooj yim dua kom tuab
2. Nws yuav siv sij hawm ntau tshaj 20 feeb kom thicken nrog dej txias, thov do txhua 5-10 feeb thaum tos.
3. Kev siv tus nqi: 0.5 ~ 2% essence; 3 ~ 5% yog '.
4. PH ntau: acid resistant rau PH3 thiab 25% cawv.
5. Lwm tus: Nws yuav tsis cuam tshuam los ntawm lwm yam khoom siv ionic.
