HPMC, tseem hu ua HydroxyPropyyl methylulose, yog lub cellulose derivative feem ntau siv los ua phau ntawv ntau lawm cov khoom lag luam ceramic. Cov khoom muaj cov khoom tshwj xeeb uas ua rau kom haum rau kev siv hauv daim ntawv thov no, suav nrog nws lub peev xwm ua rau nws cov tib leeg thiab ua ib qho kev sib cog lus muaj zog, ruaj khov, ruaj khov, ruaj ruaj, ruaj ruaj, ruaj ruaj.
Siv hpmc ua phau ntawv nyob hauv kev tsim cov khoom lag luam tej pab cuam muaj ob peb cov txiaj ntsig, suav nrog kev ua kom muaj zog ntxiv, ruaj khov thiab hnav tsis kam. Qhov no ua rau nws cov khoom zoo rau ntau cov ntawv thov, suav nrog cov vuas vov, pleev tshuaj thiab lwm cov khoom sib xyaw.
Ib qho ntawm qhov zoo ntawm kev siv HPMC ua cov nplaum nplaum yog nws lub peev xwm los ua cov ntawv sib xyaw ua ke, ntev ntev nrog cov ntaub ntawv. Qhov no yog vim cov khoom siv cov tshuaj tshwj xeeb, uas tso cai rau nws rau lwm cov feem hauv txoj kev uas yog ob qho tib si muaj zog thiab txhim khu kev qha. Cov khoom kawg yog muaj zog, ruaj thiab tiv taus hnav thiab kua muag.
HPMC kuj muaj cov khoom nplaum zoo tshaj plaws, ua rau nws zoo tagnrho rau kev siv uas yuav tsum tau ua cov Bond muaj zog. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov khoom lag luam ceramic, qhov twg cov ntaub ntawv siv yuav tsum muaj peev xwm tiv thaiv tau huab cua sov huab cua sov, ntsuas thiab lwm qhov chaw ib puag ncig.
Ntxiv rau nws cov khoom nplaum nplaum, HPMC yog ntau yam thiab tuaj yeem siv rau ntau cov ntawv thov. Qhov no ua rau nws zoo tagnrho rau cov tuam ntxhab uas xav tau cov khoom siv ntau, txhim khu kev qha kom haum rau cov kev xav tau tshwj xeeb.
Lwm qhov zoo dua ntawm kev siv HPMC ua cov cim ceramic yog nws lub peev xwm los nce cov dej tsis kam thiab ruaj khov ntawm cov khoom kawg. Qhov no yog vim cov ntaub ntawv muaj peev xwm los ua cov nyiaj sib xyaw nrog lwm cov khoom xyaw, uas pab tiv thaiv kom tiv thaiv cov dej nkag thiab cov khoom puas tsuaj.
Zuag qhia tag nrho, muaj ntau yam zoo thiab cov txiaj ntsig siv HPMC ua phau ntawv binder hauv kev tsim cov khoom lag luam. Nws yog ib qho khoom siv ntau, txhim khu kev qha kom haum rau cov kev xav tau tshwj xeeb ntawm cov ntawv thov tshwj xeeb thiab muab ntau zog, kav ntev thiab ua kom tsis taus. Yog li ntawd, nws yog qhov kev xaiv zoo tshaj plaws rau cov tuam ntxhab uas xav tsim cov khoom lag luam zoo uas muaj cov neeg ruaj khov thiab ruaj khov.
