Soluble hauv dej thiab qee cov kuab tshuaj organic tuaj yeem yaj hauv dej txias, nws qhov siab tshaj plaws tsuas yog txiav txim siab los ntawm viscosity, solubility hloov nrog viscosity, qis dua viscosity, ntau dua solubility.
Salt tsis kam: Hydroxypropyl methylcellulose rau kev tsim kho yog ib qho uas tsis yog-ionic cellulose ether thiab tsis yog polyelectrolyte, yog li nws yog ib qho ruaj khov nyob rau hauv aqueous tov thaum hlau ntsev los yog organic electrolytes muaj nyob, tab sis ntau ntxiv ntawm electrolytes yuav ua rau condensation kua nplaum thiab nag lossis daus.
Kev ua haujlwm saum npoo: vim yog lub ntsej muag ua haujlwm ntawm cov tshuaj aqueous, nws tuaj yeem siv los ua cov tshuaj tiv thaiv colloidal, emulsifier thiab dispersant.
Thaum rhuab mus rau qhov kub thiab txias, cov kua dej aqueous ntawm hydroxypropyl methylcellulose rau lub tsev thermal gel ua opaque, gels, thiab precipitates, tab sis thaum nws txias tas li, nws rov qab mus rau lub xeev cov tshuaj qub, thiab qhov condensation tshwm sim.Qhov kub ntawm cov kua nplaum thiab nag lossis daus feem ntau yog nyob ntawm lawv cov lubricants, tshem tawm cov neeg ua haujlwm, tiv thaiv colloids, emulsifiers, thiab lwm yam.
Khoom nta
Anti-mildew: Nws muaj peev xwm tiv thaiv mildew zoo thiab zoo viscosity stability thaum lub sij hawm ntev cia.
PH stability: Lub viscosity ntawm hydroxypropyl methylcellulose aqueous tov rau kev tsim kho tsis tshua muaj kev cuam tshuam los ntawm acid los yog alkali, thiab tus nqi pH yog qhov ruaj khov nyob rau hauv thaj tsam ntawm 3.0 txog 11.0.Cov duab tuav Vim tias cov kua dej muaj kuab heev ntawm hydroxypropyl methylcellulose rau kev tsim kho muaj cov khoom tshwj xeeb viscoelastic piv nrog cov tshuaj aqueous ntawm lwm cov polymers, nws qhov sib ntxiv tuaj yeem txhim kho lub peev xwm los tswj cov duab ntawm cov khoom siv ceramic extruded.
Kev tuav dej: hydroxypropyl methylcellulose rau kev tsim kho muaj cov hydrophilicity thiab siab viscosity ntawm nws cov kua aqueous, uas yog ib tug high-efficiency dej tuav tus neeg saib xyuas.
Lwm yam khoom: thickener, film-forming agent, binder, lubricant, suspending agent, tiv thaiv colloid, emulsifier, thiab lwm yam.
