Ezimonyoni, kunezinto eziningi zamakhemikhali ezingenambala nezingenaphunga, kodwa zimbalwa izinto ezingenabuthi. Namuhla ngizokwethulai-hydroxyethyl cellulose, evame kakhulu ezimonyoni eziningi noma ezidingweni zansuku zonke.
I-Hydroxyethyl Cellulose
Eyaziwa nangokuthi (HEC) iyi-fibrous emhlophe noma ekhanyayo, engenaphunga, engenabuthi noma eqinile eyimpuphu. Ngenxa yezakhiwo zayo ezinhle zokuqina, ukumisa, ukuhlakaza, ukufaka i-emulsifying, ukunamathela, ukwenza ifilimu, ukuvikela umswakama nokuhlinzeka nge-colloid evikelayo, i-HEC isetshenziswe kabanzi emikhakheni yezokwelapha nezimonyo.
Izici Zomkhiqizo
1. I-HEC inyibilika emanzini ashisayo noma emanzini abandayo, izinga lokushisa eliphezulu noma abilayo ngaphandle kwemvula, ukuze ibe nohlu olubanzi lwezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi;
2. Ayiyona i-ionic futhi ingahlala namanye ama-polymers ancibilika emanzini, ama-surfactants nosawoti ebangeni elibanzi. Kuyi-thickener ye-colloidal enhle kakhulu yezixazululo eziqukethe ama-dielectrics aphezulu;
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 ikhono le-colloid lokuvikela liqine kakhulu.
Rolekwe-HECkwezimonyo
Isisindo samangqamuzana ezimonyoni, ukuminyana kwezinto ezifana nama-synthetics emvelo kanye nama-synthetics okwenziwa ahlukile, ngakho-ke kuyadingeka ukwengeza i-solubilizer ukuze zonke izithako zisebenze kahle kakhulu. Izakhiwo ze-solubility ne-viscosity ze-hydroxyethyl cellulose zidlala indima ngokugcwele, futhi zigcina isici esinokulinganisela, ukuze ikwazi ukugcina isimo sangempela sezimonyo ngezikhathi zonyaka zokushintshana okubandayo nokushisayo. Ngaphezu kwalokho, inezinto zokuthambisa futhi ivame ukutholakala ezimonyoni zemikhiqizo ethambisayo. Ikakhulukazi imaski, amathoni, njll. cishe zonke zengezwe.
Umsebenziumphumela
I-Hydroxyethyl cellulose esetshenziswa kuzimonyo ezifana nama-emollients, ama-thickeners, njll. empeleni ayinabo ubuthi. Futhi kuthathwa njengomkhiqizo onguNombolo 1 wokuphepha kwemvelo yi-EWG.
