1. Kev Taw Qhia Txog Hydroxypropyl methylcellulose
Hydroxypropyl methylcellulose (HPMC)yog ib qho cellulose ether uas tsis yog ionic ua los ntawm cov khoom siv polymer ntuj los ntawm kev hloov kho tshuaj lom neeg. Nws yog siv dav hauv kev tsim kho, tshuaj, khoom noj, tshuaj pleev ib ce, txheej thiab lwm yam teb, thiab muaj ntau yam haujlwm xws li thickening, water retention, film creation, thiab adhesion.
2. Yuav siv hydroxypropyl methylcellulose li cas
Kev yaj dej txias
AnxinCel®HPMC tuaj yeem yaj ncaj qha rau hauv dej txias, tab sis vim nws cov hydrophilicity, nws yooj yim los ua cov pob. Nws raug pom zoo kom maj mam muab HPMC nchuav rau hauv dej txias uas tau do kom ntseeg tau tias muaj kev sib xyaw zoo thiab tsis txhob sib sau ua ke.
Kev yaj dej kub
Tom qab ua ntej ntub HPMC nrog dej kub, ntxiv dej txias kom nws o thiab ua kom sib npaug. Txoj kev no haum rau HPMC uas muaj viscosity siab.
Kev sib tov hmoov qhuav
Ua ntej siv HPMC, nws tuaj yeem sib xyaw nrog lwm cov hmoov raw, thiab tom qab ntawd do thiab yaj nrog dej.
Kev lag luam tsim kho
Hauv cov hmoov mortar thiab putty, qhov ntxiv ntawm HPMC feem ntau yog 0.1% ~ 0.5%, uas yog siv los txhim kho kev khaws cia dej, kev ua haujlwm ntawm kev tsim kho thiab kev ua haujlwm tiv thaiv kev sagging.
Kev lag luam tshuaj
HPMC feem ntau siv rau hauv cov ntsiav tshuaj txheej thiab cov matrix tso tawm tas mus li, thiab nws cov koob tshuaj yuav tsum tau kho raws li cov mis tshwj xeeb.
Kev lag luam zaub mov
Thaum siv los ua cov khoom ua kom tuab lossis emulsifier hauv zaub mov, cov tshuaj yuav tsum ua raws li cov qauv kev nyab xeeb zaub mov, feem ntau yog 0.1% ~ 1%.
Cov txheej txheem
Thaum HPMC siv rau hauv cov txheej txheem dej, nws tuaj yeem txhim kho qhov tuab thiab kev sib kis ntawm cov txheej txheem thiab tiv thaiv cov xim kom tsis txhob los nag.
Tshuaj pleev ib ce
HPMC yog siv los ua tus stabilizer hauv cov tshuaj pleev ib ce los txhim kho qhov kov thiab ductility ntawm cov khoom.
3. Cov kev ceev faj rau kev siv hydroxypropyl methylcellulose
Lub sijhawm yaj thiab kev tswj qhov kub
HPMC siv sijhawm ntev npaum li cas los yaj, feem ntau yog 30 feeb txog 2 teev. Qhov kub siab dhau lossis qis dhau yuav cuam tshuam rau qhov nrawm ntawm kev yaj, thiab qhov kub thiab txias tsim nyog thiab cov xwm txheej sib xyaw yuav tsum tau xaiv raws li qhov xwm txheej tshwj xeeb.
Tsis txhob sib sau ua ke
Thaum ntxiv HPMC, nws yuav tsum tau maj mam tawg thiab do kom huv si kom tiv thaiv kev sib sau ua ke. Yog tias muaj kev sib sau ua ke, nws yuav tsum tau tso tseg ib ntus thiab do tom qab nws o tag.
Kev cuam tshuam ntawm cov av noo ib puag ncig
HPMC rhiab heev rau cov av noo thiab nws yooj yim nqus cov dej noo thiab sib sau ua ke hauv qhov chaw noo noo siab. Yog li ntawd, yuav tsum tau saib xyuas qhov qhuav ntawm qhov chaw khaws cia thiab lub ntim khoom yuav tsum tau kaw.
Kev tsis kam ntawm acid thiab alkali
HPMC ruaj khov rau cov kua qaub thiab alkalis, tab sis nws yuav lwj hauv cov kua qaub lossis alkali muaj zog, cuam tshuam rau nws txoj haujlwm. Yog li ntawd, yuav tsum zam cov xwm txheej pH siab heev li sai tau thaum siv.
Kev xaiv cov qauv sib txawv
HPMC muaj ntau yam qauv (xws li viscosity siab, viscosity qis, yaj sai, thiab lwm yam), thiab lawv cov kev ua tau zoo thiab kev siv sib txawv. Thaum xaiv, tus qauv tsim nyog yuav tsum tau xaiv raws li qhov xwm txheej ntawm daim ntawv thov tshwj xeeb (xws li cov ntaub ntawv tsim kho, tshuaj, thiab lwm yam) thiab cov kev xav tau.
Kev huv thiab kev nyab xeeb
Thaum siv AnxinCel®HPMC, yuav tsum hnav cov khoom siv tiv thaiv kom tsis txhob nqus tau hmoov av.
Thaum siv rau hauv cov khoom noj thiab tshuaj, nws yuav tsum ua raws li cov cai thiab cov qauv ntawm kev lag luam cuam tshuam.
Kev sib raug zoo nrog lwm cov khoom ntxiv
Thaum sib xyaw nrog lwm cov ntaub ntawv hauv cov mis, yuav tsum tau them sai sai rau nws qhov sib xws kom tsis txhob muaj nag lossis daus, coagulation lossis lwm yam kev tsis zoo.
4. Kev khaws cia thiab kev thauj mus los
Kev Khaws Cia
HPMCyuav tsum khaws cia rau qhov chaw txias thiab qhuav, tsis txhob kub thiab av noo. Cov khoom tsis siv yuav tsum tau kaw kom ruaj.
Kev Thauj Mus Los
Thaum lub sijhawm thauj mus los, nws yuav tsum tau tiv thaiv los ntawm nag, dej noo thiab kub siab kom tsis txhob muaj kev puas tsuaj rau lub ntim khoom.
Hydroxypropyl methylcellulose yog ib yam khoom siv tshuaj lom neeg uas xav tau kev tshawb fawb thiab kev tsim nyog los yaj, ntxiv thiab khaws cia rau hauv kev siv tiag tiag. Ua tib zoo saib xyuas kom tsis txhob muaj kev sib sau ua ke, tswj cov xwm txheej yaj, thiab xaiv cov qauv thiab cov koob tshuaj raws li cov xwm txheej ntawm kev siv sib txawv kom ua tau zoo tshaj plaws. Tib lub sijhawm, cov qauv kev lag luam yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tias kev siv HPMC muaj kev nyab xeeb thiab ua haujlwm tau zoo.
