Hydroxypropyl Methyl Cellulose (HPMC) Siv rau cov xim dej

Peb cov cellulose ether dej tuav kev ua tau zoo rau cov txheej txheem latex, tshwj xeeb tshaj yog cov txheej PVA siab muab cov txheej txheem zoo heev, txheej rau cov tawv nqaij tuab, yuav tsis tsim flocculation; Nws cov nyhuv thickening siab tuaj yeem txo qhov ntau npaum, txhim kho kev lag luam ntawm kev tsim, thiab txhim kho qhov kev ncua ntawm txheej txheej. Cov khoom zoo rheological hauv txheej txheej, tuaj yeem nyob hauv lub xeev zoo li qub, ua kom lub xeev thickening zoo tshaj plaws ntawm txheej; Nyob rau hauv lub pov tseg lub xeev, nrog zoo heev fluidity, thiab yuav tsis txaws; Hauv cov txheej txheej thiab cov menyuam txheej, yooj yim rau kev sib kis hauv substrate, kev tsim kho yooj yim; Thaum txheej txheej tiav lawm, lub viscosity ntawm lub kaw lus yuav rov qab tam sim ntawd, lub txheej yuav tam sim ntawd ntws.

Nyob rau hauv lub ntiaj teb no vibrant heev ntawm cov dej raws li latex xim, ib qho tseem ceeb additive yog Hydroxy Propyl Methyl Cellulose(HPMC). Dhau li ntawm qhov ua tau zoo ntawm cov thickener, hom additive no kuj muab cov tswv tsev ntawm lwm cov khoom muaj txiaj ntsig, xws li txhuam-muaj peev xwm, sag tsis kam, emulsification, ncua lub zog, thiab lwm yam, thaum muab cov xim zoo sib xws,kujua hom thickener no nrov heev nrog ntau lub tuam txhab xim hauv ntiaj teb.

Siv rau hauv cov xim pleev xim dej. Nws qhia tau hais tias nws zoo heev high thickening nyhuv,thiabrheological zog, dispersion thiab solubility. Nws muaj bio-stability zoo, muab sijhawm txaus rau lub khw muag xim. Zoo tiv thaiv pigments thiab muab tub lim sedimentation.
