Ob peb hnub dhau los, cov tub ntxhais kawm tau teeb meem los ntawm cov kua xab npum tuab. Qhov tseeb, ua kom ncaj ncees, kuv tsis tshua muaj cov kua xab npum. Txawm li cas los xij, kuv kuj tau qhia hauv chav kawm tias muaj ntau txoj hauv kev kom ua tiav qhov no. Cov tshuaj thiab thickening txoj kev qhia niaj hnub no tuaj yeem ua lwm txoj hauv kev.
yam ntxwv:
HEC Hydroxy ethyl cellulose tseem hu ua macromolecular cellulose (los yog macromolecular polymer)
Cov khoom siv raw yog hloov kho los ntawm cov nroj tsuag ntuj fibers thiab muaj kev xav zoo heev!
Nws yog cov hmoov dawb (daj) hmoov, uas tsis yog-ionic dej-soluble polymer compound, uas tuaj yeem siv los ua cov thickening tus neeg sawv cev thiab tus neeg sawv cev ncua
Nws yog qhov yooj yim rau kev khiav dej num hauv dej kub dua li hauv dej txias, nws yuav tsum tau ua kom nplawm, thiab tus nqi pH yog khaws cia siab tshaj 6, uas yooj yim rau yaj.
Feem ntau siv nyob rau hauv ntau yam kev zoo nkauj thiab tu cov khoom, nws muaj ib tug kov zoo ib yam li hyaluronic acid, cov khoom tiav yog pob tshab thiab muaj lub siab tshaj plaws acid kuj.
Ua kua xab npum thickening:
Siv 1-2% concentration, ntxiv 1g ntawm ethyl cellulose rau 99g ntawm distilled dej thiab do, thaum tos, thov do txhua 5 ~ 10 feeb, tsis txhob cia cov hmoov cov ntaub ntawv nyob rau hauv, kom txog rau thaum lub gel yog pob tshab, ces ntxiv mix zoo. hauv kua xab npum.
Kev siv tshuaj pleev ib ce:
1. Ethyl cellulose tuaj yeem siv los ua pob tshab colloid, uas feem ntau yog siv los ua cov khoom lag luam siab heev, gel, 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 Q degree thiab sib xws ntawm cov tshuaj nplaum.
Cov lus qhia rau kev siv:
1. Cov dej kub yog yooj yim dua kom tuab
2. Tos ntau tshaj 20 feeb thaum cov dej txias thickens, thiab do txhua 5 ~ 10 feeb thaum tos.
3. Kev siv tus nqi: 0.5 ~ 2% essence; 3 ~ 5% yog '.
4. PH ntau: acid-resistant PH3 thiab 25% cawv.
5. Lwm tus: yuav tsis cuam tshuam los ntawm lwm yam ionic raw khoom.
