Kwezi ntsuku zimbalwa zidlulileyo, abafundi baye bakhathazwa kukujiya kweesepha ezingamanzi. Enyanisweni, xa ndithetha inyani, andifane ndijiye iisepha ezimanzi. Nangona kunjalo, ndiye ndafundisa eklasini ukuba zininzi iindlela zokuphumeza oku. Amachiza kunye neendlela zokujiya eziziswe namhlanje zinokuba nenye indlela.
uphawu:
I-HEC I-Hydroxy ethyl cellulose ikwabizwa ngokuba yi-macromolecular cellulose (okanye i-macromolecular polymer)
Imathiriyeli ekrwada iguqulwe ukusuka kwimicu yendalo yezityalo kwaye inovakalelo oluhle kakhulu olutyibilikayo!
Ingumgubo omhlophe (otyheli) omhlophe, i-polymer e-non-ionic yamanzi e-soluble water-soluble polymer compound, enokusetyenziswa njenge-agent agent kunye ne-agent yokumisa.
Kulula ukusebenza emanzini ashushu kunamanzi abandayo, kufuneka igcinwe ivuselela, kwaye ixabiso le-pH ligcinwe ngaphezu kwe-6, elula ukunyibilika.
Idla ngokusetyenziswa kwiimveliso ezahlukeneyo zobuhle kunye nokucoca, inochuku olufana ne-hyaluronic acid, imveliso egqityiweyo ibonakala ngakumbi kwaye inokumelana ne-asidi ephezulu.
Ukujiya isepha elulwelo:
Sebenzisa i-1-2% yoxinaniso, yongeza i-1g ye-ethyl cellulose kwi-99g yamanzi adibeneyo kwaye ugxobhoze, ngelixa ulindile, nceda uvuselele yonke i-5 ~ 10 imizuzu, ungavumeli ukuba izinto zomgubo zihlale, de ijeli ibonakale, emva koko yongeza Xuba kakuhle. kwisepha engamanzi.
Usetyenziso lwezithambiso:
1. I-Ethyl cellulose ingasetyenziselwa ukwenza i-colloid ecacileyo, esetyenziswa ngokubanzi ekuveliseni i-essence ephezulu, i-gel, imaski yobuso kunye ne-shampoo.
2. Ingasetyenziselwa njenge-agent yokumisa kunye nokuqina kwiimveliso zekhilimu ukulungelelanisa i-Q degree kunye nokuhambelana kwekhilimu.
Imiyalelo yokusetyenziswa:
1. Amanzi ashushu kulula ukujiya
2. Linda ngaphezu kwemizuzu engama-20 xa amanzi abandayo ejiya, kwaye uvuselele yonke imizuzu emi-5 ~ 10 ngelixa ulindile.
3. Izinga lokusetyenziswa: 0.5 ~ 2% isiseko; 3 ~ 5% ijeli.
4. Uluhlu lwe-PH: i-asidi-resistant kwi-PH3 kunye ne-25% yotywala.
5. Abanye: abayi kuchaphazeleka zezinye izinto ze-ionic eluhlaza.
