Yintoni i-HPMC kwiziXhobo?

1. Iwashing thickener

I-HPMC yokucoca yaziwa ngokuba yi-chemical grade hydroxypropyl methylcellulose. Usetyenziso lwayo lubandakanya izinto zokucoca, iisepha, iishampu, iishampu, izihlambi zomzimba, izicoci zobuso, intlama yamazinyo, izinto zokuthambisa, njl.

IHydroxypropyl methylcellulose isetyenziswa njengento etyebisayo kwizicoci kwaye sisidibaniso esisetyenziswa ngokuqhelekileyo. Isiphumo esityebileyo se-HPMC kwisicoci sinokunyusa i-viscosity ye-detergent kunye nokwandisa ukuzinza kwamaqamza. Zisa abasebenzisi amava amnandi. Njenge-detergent thickener, inezi ncedo zilandelayo:

1. Ukubanda kunye nokumelana nobushushu. I-viscosity ye-detergent ayitshintshi ngeqondo lokushisa.

2. Ukuxhathisa i-Electrolyte. Inyibilika kweyiphi i-pH i-HPMC? Izinzile kuluhlu lwe-pH lwe-3-11

3. Ukuphucula ubumanzi benkqubo. I-HPMC inesiphumo sokucoca kakuhle kwaye iphucula ukuthungwa kwesikhumba.

2. I-ejenti yokuchasa ukubuyisela kwakhona

I-HPMC esetyenziswa kwisicoci ayisosicoci esijiyileyo kuphela, kodwa ikwayi-arhente yokuchasa ukungcola. Isiphumo sokucocwa kwe-detergent kukungena phakathi kwe-detergent kunye nokungcola. Ngoko ukungcola (izinto ezinamafutha kunye nokungcola okuqinileyo) kuyaphuma. Emva koko i-emulsified kwaye ihlakazwe kwisisombululo. I-HPMC ineentlawulo ezininzi ezimbi, ezinokuthi zibhengeze kwaye zisuse ukungcola. Ukonyuka kwe-electrostatic repulsion. Ngoko ukungcola okuhlanjwe phantsi kunokuchithwa kwaye kunqunyanyiswe emanzini. Ithintela ukungcola ukuba kungazinzi kwakhona.

Kodwa umgangatho we-detergent awuxhomekeke kwi-viscosity, kodwa kwizinto ezisebenzayo. Isithako esisebenzayo sithathwe kwi-detergent surfactants. Ii-surfactants kunye nabakhi zizinto ezimbini eziphambili zeekhemikhali zokucoca. Indima yesongezo kukwenza i-surfactant isebenze. Ukunciphisa inani le-surfactant kunye nokuphucula umphumo wokuhlamba.

Abaninzi abavelisi be-detergent bahlawula ingqalelo ngakumbi ekucaceni kwayo kunye nesantya sokuchithwa. Ukwenziwa kwezinto elubala kufuneka ubuncinane kube ngama-95%. Imigangatho enjalo yokungafihli ayichaphazeli ukubonakala kwe-detergent. Ithandwa kakhulu ngabathengi.
