Ezinsukwini ezimbalwa ezedlule abafundi bakhathazwe wukuqina kwezinsipho eziwuketshezi. Eqinisweni, uma ngikhuluma iqiniso, angivamile ukujiyisa insipho ewuketshezi. Kodwa-ke, ngifundise ekilasini ukuthi ziningi izindlela zokufeza lokhu. Izinto kanye nezindlela zokujiya ezethulwe namuhla zingaba ngenye indlela.
isici:
I-HEC Hydroxy ethyl cellulose yaziwa nangokuthi i-macromolecular cellulose (noma i-macromolecular polymer)
Impahla eluhlaza iguqulwa isuka kumicu yezitshalo yemvelo futhi inomuzwa omuhle kakhulu oshelelayo!
Kuyimpushana emhlophe (ephuzi), inhlanganisela ye-polymer encibilika emanzini engeyona i-ionic, engasetshenziswa njenge-ejenti yokuqina kanye ne-ejenti elengayo.
Kulula ukusebenza emanzini ashisayo kunasemanzini abandayo, kufanele igcinwe inyakaza, futhi inani le-pH ligcinwa lingaphezulu kuka-6, okulula ukulincibilika.
Imvamisa isetshenziswa emikhiqizweni ehlukahlukene yobuhle neyokuhlanza, inokuthinta okufana ne-hyaluronic acid, umkhiqizo oqediwe usobala futhi unokumelana okuphezulu kwe-asidi.
Ukuqina kwensipho ewuketshezi:
Sebenzisa i-concentration engu-1-2%, engeza i-1g ye-ethyl cellulose ku-99g wamanzi acwecwe futhi ugovuze, ngenkathi ulindile, sicela uyivuse njalo ngemva kwemizuzu engu-5 ~ 10, ungavumeli i-powder material ihlale, kuze kube yilapho ijeli ibonakala, bese ufaka Hlanganisa kahle. insipho ewuketshezi.
Isicelo sezimonyo:
1. I-Ethyl cellulose ingasetshenziswa ukwenza i-colloid esobala, evame ukusetshenziswa ekukhiqizeni i-essence ethuthukisiwe, ijeli, imaski yobuso kanye ne-shampoo.
2. Ingasetshenziswa njenge-ejenti yokumisa kanye nokuqina kwemikhiqizo kakhilimu ukulungisa i-Q degree kanye nokuvumelana kwekhilimu.
Imiyalo yokusetshenziswa:
1. Amanzi ashisayo kulula ukujiya
2. Linda imizuzu engaphezu kwengu-20 lapho amanzi abandayo eshuba, bese ugovuza njalo ngemva kwemizuzu engu-5–10 ngesikhathi ulindile.
3. Izinga lokusetshenziswa: 0.5~2% ingqikithi; 3-5% ijeli.
4. Ibanga le-PH: imelana ne-asidi ku-PH3 kanye no-25% wotshwala.
5. Abanye: ngeke bathintwe ezinye izinto zokusetshenziswa ze-ionic.
