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.Umphumela 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 nokuqeda inhlabathi.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 kungahlali futhi.

Kodwa izinga le-detergent alixhomeki ku-viscosity, kodwa kuzithako 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%.Izindinganiso ezinjalo zokungafihli akuthinti ukubukeka kwe-detergent.Idume kakhulu kubathengi.
