Iyini i-HPMC kuma-Detergents?

1. Ukugeza ukuqina

I-Detergent HPMC yaziwa nangokuthi i-chemical grade hydroxypropyl methylcellulose yansuku zonke. Izicelo zayo zihlanganisa okokuhlanza, insipho, ama-shampoos, okokugeza umzimba, okokuhlanza ubuso, okokuxubha amazinyo, okokugcoba, njll.

IHydroxypropyl methylcellulose isetshenziswa njengokuqina kwezihlanzi futhi iyisengezo esisetshenziswa kakhulu. Umthelela wokujiya we-HPMC kumshini wokuhlanza ungakhuphula i-viscosity yesihlanzi futhi ukhuphule ukuzinza kwamabhamuza. Letha abasebenzisi ukuzizwisa okunethezekile. Njenge-thickener ye-detergent, inezinzuzo ezilandelayo:

1. Ukumelana nokubanda nokushisa. I-viscosity ye-detergent ayishintshi nezinga lokushisa.

2. Ukumelana ne-Electrolyte. I-HPMC incibilika kuyiphi i-pH? Izinzile ku-pH engu-3-11

3. Thuthukisa i-fluidity yesistimu. I-HPMC inomphumela wokuhlanza obushelelezi futhi ithuthukisa ukuthungwa kwesikhumba.

2. I-ejenti yokuhlanza i-anti-deposition

I-HPMC esetshenziswa okokuhlanza akuyona nje into yokuhlanza okokuhlanza kuphela, kodwa futhi iyi-ejenti elwa nokudumba. Umthelela wokuqeda ukungcola wokuhlanza uwukungena phakathi kwezinto zokuhlanza nokungcola. Ngakho-ke ukungcola (izinto ezinamafutha kanye nokungcola okuqinile) kuyaphuma. Khona-ke i-emulsified futhi ihlakazwe ngesisombululo. I-HPMC inamacala amaningi amabi, angakhangisa futhi asuse ukungcola. Ukwenyuka kwe-electrostatic repulsion. Ngakho ukungcola okugezwe phansi kungahlakazwa futhi kumiswe emanzini. Ivimbela ukungcola ukuthi kungazinzi futhi.

Kodwa ikhwalithi ye-detergent ayincikile ku-viscosity, kodwa izithako ezisebenzayo. Isithako esisebenzayo sitholakala kuma-detergent surfactants. Ama-surfactants kanye nabakhi yizingxenye ezimbili zamakhemikhali eziyinhloko zezihlanzi. Indima yesithasiselo ukwenza i-surfactant isebenze. Yehlisa inani le-surfactant futhi uthuthukise umphumela wokugeza.

Abakhiqizi abaningi bokuhlanza banaka kakhulu ukucaca kwayo kanye nesivinini sokuhlakazeka. Ukucaca kumele okungenani kube ngu-95%. Amazinga anjalo okukhanya akuthinti ukubukeka kwe-detergent. Idume kakhulu kubathengi.
