Ezimonyoni, kunezinto eziningi zamakhemikhali ezingenambala nezingenaphunga, kodwa zimbalwa izinto ezingenabuthi. Namuhla, ngizokwethula, i-hydroxyethyl cellulose, evame kakhulu kuzimonyo eziningi noma izidingo zansuku zonke.
I-Hydroxyethyl Cellulose【I-Hydroxyethyl Cellulose】
Eyaziwa nangokuthi (HEC) iphuzi elimhlophe noma eliphaphathekile, elingenaphunga, elingenabuthi noma okuqinile okuyimpuphu. Ngenxa yokuthi i-HEC inezici ezinhle zokuqina, ukumisa, ukuhlakazeka, ukufaka i-emulsifying, ukubopha, ukwenza ifilimu, ukuvikela umswakama nokuhlinzeka nge-colloid evikelayo, iye yasetshenziswa kabanzi ekusetshenzisweni kwezokwelapha nezimonyo.
Izici Zomkhiqizo
I-1.HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayincibiliki ekushiseni okuphezulu noma ekubiliseni, okwenza ibe nohlu olubanzi lwezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engeyona eshisayo;
2. I-non-ionic ngokwayo ingahlala kanye nohlu olubanzi lwama-polymers ancibilikayo emanzini, ama-surfactants nama-salts, futhi iyi-colloidal thickener enhle kakhulu equkethe izixazululo ze-dielectric eziphezulu zokugxila;
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono;
4. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa i-colloid evikelayo inekhono eliqine kakhulu.
indima kwezimonyo
Isisindo samangqamuzana sezimonyo, ukuminyana kwezinhlanganisela zemvelo, izinhlanganisela zokwenziwa nezinye izakhi zihlukile, ngakho-ke kuyadingeka ukwengeza i-agent encibilikayo ukwenza zonke izithako zidlale indima engcono kakhulu. Izakhiwo ze-solubility kanye ne-viscosity ze-hydroxyethyl cellulose zidlala indima ngokugcwele, futhi zigcina ibhalansi, ukuze ukwakheka kwangempela kwezimonyo kugcinwe ezikhathini zonyaka ezibandayo nokushisa. Ngaphezu kwalokho, inezinto zokuthambisa futhi ivamile ezimonyoni zemikhiqizo ethambisayo. Ikakhulukazi, imaski, amathoni, njll. cishe zonke zengezwe.
umphumela ohlangothini
I-Hydroxyethyl cellulose esetshenziswa kuzimonyo ngokuyisisekelo ayinabo ubuthi uma usebenzisa izinto ezithambisayo, ukuqina, njll. Futhi ithathwa njengomkhiqizo onguNombolo 1 wokuphepha kwemvelo yi-EWG.
