Kev txhim kho cov txheej xwm HPMC ntau lawm thiab cov txheej txheem ntawm hydroxyprropy cellulose hauv Suav teb

HydroxyPropyl cellulose hpmcrau cov kev tsim tawm tam sim no tau muab ua ntej rau cov txheej txheem kev tshawb fawb txog kev lag luam, yog li cov txheej txheem tshawb fawb txog etherification ntawm cov txheej txheem tseem ceeb ntawm qee qhov Zoo-paub cellulose ether cov tuam tsev.

Kev tsim kho lub ntsej muag hydrox cellulose feem ntau siv cov ntaub paj rwb rearing lossis siv cov khoom siv hluav taws xob (qee cov chaw tsim khoom sib tsoo kuj tseem siv cov tshuaj lom neeg organic, cov tshuaj tiv thaiv nyob hauv txoj kab sib dhos. Cov txheej txheem lim dej siv cov txheej txheem sib quas ntus uas cov organic thiab cov roj av tau ntxuav tau los ntawm kev ntxhua khaub ncaws thiab lub cev qhuav dej los ntawm cov twj ntxuav thiab dej hiav txwv. Ua tiav cov khoom lag luam nrog cov granittent, nyob rau hauv cov kev tsim khoom cua kub (muaj kuj muaj kev sib tw tsis muaj kev sib tw thiab kev faib tawm sai sai

Cov theem theem muaj cov txiaj ntsig hauv qab no: Cov txheej txheem txheej txheem cov khoom siv sab hauv yog me me, muaj peev xwm pheej hmoo, tsawg; Tom qab impregnating nyob lye, cellulose tuaj yeem nthuav dav thiab tusyees alkalized. Lye tau zoo dua infiltration thiab o ntawm cellulose. Lub EhereForification reactor yog me me, txuas nrog cov khoom o ntawm alkali cellulose, yog li qhov zoo dua cov khoom lag luam, ntau yam kuj yooj yim los hloov.

Txawm li cas los xij, tus txheej txheem no tseem muaj cov tshuaj tsis zoo hauv qab no: Cov tshuaj reactor feem ntau tsis muaj peev xwm ua kom muaj qhov loj me, txhawm rau txhim kho cov zis me me, nws yog qhov tsim nyog kom nce cov neeg reactors; Kho kom zoo nkauj thiab huv cov khoom lag luam xav tau cov cuab yeej siv ntau dua, kev ua haujlwm nyuaj, kev siv zog; Vim tias tsis muaj anti-mildew thiab compound kev kho mob, ua rau cov khoom lag luam viscosity thiab cov nqi ntau lawm cuam tshuam; Ntim los ntawm phau ntawv txoj kev, kev siv zog ua haujlwm, tus nqi zog siab; Cov automation degree ntawm kev tswj hwm yog qis dua li ntawm cov txheej txheem roj av, yog li cov tswj xyuas qhov tseeb yog qhov tsawg. Piv nrog cov txheej txheem roj av, complex solvent rov qab cov tshuab yuav tsum tau ua.

Nrog kev txhim kho ntawm hydroxypropyl cellulose hydulose thev naus laus zis, loj Kettle Ligh txoj kev tau tsim los ntawm kev ua haujlwm ywj pheej Ntxhiv kev txhawj xeeb siv cov txheej txheem HPMC ntau lawm, tsis muaj kev sib xyaw ua ke, thiab cov tshuaj tiv thaiv tau tsuas yog, thiab tib lub sijhawm ua haujlwm tau zoo, thiab tib lub sijhawm kom ntseeg tau tias cov khoom lag luam zoo. HPMC cov kab ntau lawm ntawm qee cov lag luam tau raug kaw lus hloov kho, ua kom muaj kev tswj hwm ua haujlwm, kev nyab xeeb ntawm kev tsim khoom siv, uas tsis yog tsuas yog txuag manepower, Txo kev siv zog ua haujlwm, tab sis kuj tseem txhim kho cov haujlwm ua haujlwm ntawm lub xaib.
