Hydroxypropyl Methylcellulose (HPMC)yog cov hmoov dawb lossis cov khoom siv granular uas tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis khaus, uas siv dav hauv tshuaj, khoom noj, tshuaj pleev ib ce thiab cov ntaub ntawv tsim kho.
1. Yuav siv hydroxypropyl methylcellulose li cas
Txoj kev yaj
HPMC muaj kev yaj zoo hauv dej txias thiab tuaj yeem tsim cov kua pob tshab lossis mis nyuj colloidal. Cov kauj ruam tshwj xeeb ntawm kev yaj yog raws li nram no:
Txoj kev yaj dej txias: Maj mam muab HPMC nchuav rau hauv dej txias uas sib xyaw, tsis txhob ntxiv dej kub ncaj qha kom tiv thaiv kev sib sau ua ke.
Txoj kev yaj dej kub: Sib tov AnxinCel®HPMC nrog ib feem ntawm dej kub thiab do kom txog thaum nws nthuav dav, tom qab ntawd ntxiv dej txias rau qhov ntim xav tau, thiab txuas ntxiv do kom txog thaum nws yaj tag.
Kev tswj hwm tshuaj
Qhov ntau npaum li cas ntawm HPMC nyob ntawm daim ntawv thov tshwj xeeb:
Kev lag luam tshuaj: Ua tus neeg sawv cev txheej lossis cov khoom siv tso tawm ntev rau cov ntsiav tshuaj, qhov kev siv ntau yog 1% txog 5%.
Kev lag luam zaub mov: Siv ua cov khoom ua kom tuab lossis stabilizer, qhov ntxiv ntau yog 0.1% txog 0.5%.
Kev tsim kho teb: siv ua tus khaws dej thiab thickener hauv mortar thiab putty hmoov, nrog rau qhov ntxiv ntawm 0.3% txog 1%.
Daim ntawv thov
HPMC tuaj yeem ntxiv rau cov khoom sib txawv hauv daim ntawv ntawm hmoov lossis kua. Feem ntau, nws qhov sib xws nrog lwm cov khoom xyaw yuav tsum tau ua kom ntseeg tau thaum lub sijhawm tsim cov mis.
2. Kev ceev faj rau Hydroxypropyl Methylcellulose
Kev tswj qhov kub ntawm kev yaj
HPMC rhiab heev rau qhov kub ntawm dej. Nws raug pom zoo kom khaws qhov kub ntawm dej hauv qab 60 ° C thaum lub sijhawm yaj. Yog tias xav tau kev yaj sai, nws raug nquahu kom siv dej txias los yaj nws ua ntej, thiab tom qab ntawd ntxiv dej kub kom ua kom nws cov viscosity.
Tsis txhob sib sau ua ke
Thaum ntxiv HPMC, maj mam muab nws nchuav rau hauv dej thiab do tas li. Tsis txhob nchuav ntau dhau ib zaug, txwv tsis pub nws yuav ua rau muaj cov pob uas nyuaj rau tawg.
Cov xwm txheej cia khoom
HPMC yuav tsum khaws cia rau hauv qhov chaw qhuav thiab txias, deb ntawm tshav ntuj ncaj qha thiab cov av noo siab kom tiv thaiv nws los ntawm kev nqus cov dej noo thiab agglomerating, cuam tshuam rau kev siv cov txiaj ntsig.
Kev xeem sib xws
Ua ntej siv AnxinCel®HPMC hauv cov mis, yuav tsum tau kuaj xyuas kev sib raug zoo nrog lwm cov khoom siv raw kom paub tseeb tias tsis muaj tshuaj lom neeg tshwm sim lossis cuam tshuam rau kev ua haujlwm ntawm cov khoom kawg.
Siv ib puag ncig
Hauv kev siv rau kev tsim kho,HPMCNws yooj yim rau qhov kub thiab av noo ntawm qhov chaw tsim kho. Nws qhov kev ua haujlwm khaws dej yog qhov tseem ceeb tshwj xeeb hauv qhov kub thiab txias lossis qhuav. Nws raug pom zoo kom saib xyuas kom zoo tom qab tsim kho kom ntseeg tau tias muaj txiaj ntsig zoo tshaj plaws.
Tsis txhob sib xyaw nrog cov kua qaub thiab alkalis muaj zog
AnxinCel®HPMC tej zaum yuav poob qis lossis nws txoj kev ua haujlwm yuav txo qis hauv cov chaw muaj kua qaub lossis alkali, yog li yuav tsum tau saib xyuas tshwj xeeb rau kev tswj pH thaum tsim cov mis.
Kev nyab xeeb thiab kev tiv thaiv ib puag ncig
HPMC yog cov khoom tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij, tab sis yuav tsum tsis txhob ua pa plua plav thaum lub sijhawm ua lossis siv, thiab nws raug pom zoo kom hnav lub npog ntsej muag tiv thaiv. Thaum pov tseg cov khib nyiab, yuav tsum ua raws li cov cai tiv thaiv ib puag ncig hauv zos.
Hydroxypropyl methylcelluloseNws ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw vim nws cov dej zoo heev, ua kom tuab thiab ua zaj duab xis. Cov txheej txheem siv thiab kev ceev faj kom raug tsis yog tsuas yog txhim kho nws cov txiaj ntsig ntawm kev siv xwb, tab sis kuj ua kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig ntawm cov txheej txheem siv. Thaum ua haujlwm tiag tiag, cov neeg siv yuav tsum hloov kho cov mis raws li qhov xav tau tshwj xeeb thiab ua raws li cov lus qhia kom ua tiav nws cov txiaj ntsig.
