HPMC YB 5150MS
EipponCellHPMC YB 5150MS yog ib hom Hydroxypropyl methylcellulose uas qhia tau tias muaj kev solubility tsawg hauv ethanol, ether, thiab acetone.Txawm li cas los xij, thaum raug dej kub ntawm qhov kub ntawm 80 mus rau 90 ° C, nws tawg sai sai thiab mob o, thaum kawg yaj sai sai thaum txias.Cov tshuaj aqueous ntawm qhov sib xyaw no nthuav tawm qhov kev ruaj ntseg zoo kawg li ntawm chav tsev kub thiab muaj peev xwm tsim cov gels thaum raug kub siab.Cov gels no nthuav tawm qhov ntsuas kub-nyob ntawm qhov hloov pauv hauv qhov sib xws.
EipponCellHPMC YB 5150MS muaj ntau yam khoom tshwj xeeb, suav nrog kev ntub dej zoo, dispersibility, adhesiveness, thickening, emulsification, dej tuav, thiab kev ua yeeb yaj kiab.Tsis tas li ntawd, nws nthuav tawm impermeability rau roj.Cov yeeb yaj kiab tsim los ntawm cov khoom sib xyaw no qhia tau zoo heev rau qhov toughness, yooj, thiab pob tshab.Ua tsis yog-ionic hauv xwm, nws tuaj yeem yooj yim coexist nrog lwm cov emulsifiers.Txawm li cas los xij, nws muaj kev cuam tshuam rau ntsev los nag thiab tswj kev daws teeb meem nyob rau hauv pH ntau ntawm 2 txog 12.

HPMC YB 5200MS
EipponCell HPMC YB 5200MS yog hydroxypropyl methylcellulose ether nrog viscosity siab tshaj plaws muaj rau kev saib xyuas hauv tsev thiab daim ntawv thov kev saib xyuas tus kheej.Nrog viscosity ntawm 200,000, nws yog tsim tshwj xeeb rau kev siv hauv cov khoom siv tshuaj txhua hnub.HPMC variant no tuaj yeem yaj tau yooj yim hauv dej kub thiab dej txias, tab sis nws feem ntau insoluble hauv cov kuab tshuaj organic.Nws nthuav tawm zoo heev solubility thiab viscosity yam ntxwv, nyob ruaj khov txawm nyob rau hauv high kub los yog boiling.Tsis tas li ntawd, nws undergoes non-thermal gelation thiab muaj tsawg heev tom qab-thickening teebmeem.Kev ruaj ntseg ntawm HPMC nyob rau hauv ntau yam mob yog qhov zoo kawg li.
Thaum ua hauj lwm hydroxypropyl methylcellulose ether nyob rau hauv lub cheeb tsam ntawm cov tshuaj niaj hnub, nws tshwj xeeb cov khoom ua rau nws ib tug nrov xaiv raws li ib tug thickener, emulsifier, thiab binder nyob rau hauv ntau yam khoom txhua hnub.Txhawm rau siv nws kom zoo, HPMC feem ntau yog yaj hauv ib qho dej tshwj xeeb thaum lub sij hawm nplawm kom tsim tau cov kua dej ntshiab thiab du.Nws yog ib qho tseem ceeb kom tsis txhob shoveling los yog pov tseg HC thiab tuav nruam nplawm kom txog thaum qhov kev xav tau sib xws.Nws raug nquahu kom tsis txhob qhia lwm yam tshuaj thaum lub sijhawm ua haujlwm no kom tsis txhob muaj kev cuam tshuam rau lub cev tus nqi pH.Txhawm rau txhim kho cov khoom lag luam zoo, nce qhov kub thiab pH tus nqi ntawm lub kaw lus pom zoo.
