Hydroxylopenyl cellulose (HPMC) yog ib qho hluavtaws polymer uas tau siv dav hauv ntau yam kev siv xws li tshuaj, khoom noj, tsev thiab tshuaj pleev ib ce.Nws yog ib qho derivative ntawm cellulose thiab tsim cov kua nplaum coagulant ntawm hydrophilic.Daim ntawv ntshiab ntawm HPMC yog cov hmoov dawb tsis qab ntsev uas yaj hauv dej los tsim cov kua nplaum pob tshab.
HPMC kev deev luag poj luag txiv yog cov txheej txheem ntawm kev ntxiv lossis sib xyaw cov tshuaj ntshiab rau lwm cov ntaub ntawv los hloov nws cov yam ntxwv lossis txo cov nqi tsim khoom.Cov doping hauv HPMC tuaj yeem hloov pauv lub cev, tshuaj lom neeg thiab khoom siv hluav taws xob ntawm HPMC.HPMC siv ntau cov tshuaj doping, suav nrog cov hmoov txhuv nplej siab, cov protein ntau, cellulose, sucrose, qabzib, carboxymethyl cellulose sodium (CMC) thiab polyethylene ethylene (PEG).Qhov sib ntxiv ntawm cov neeg laus no yuav ua rau qhov zoo, kev nyab xeeb thiab kev ua tau zoo ntawm HPMC.
Muaj ntau qhov sib txawv ntawm cov ntshiab HPMC thiab kev ua phem rau cellulose:
1. Pureness: Qhov sib txawv tseem ceeb ntawm cov ntshiab HPMC thiab kev deev deev cellulose yog lawv purity.Pure HPMC yog ib yam khoom uas tsis muaj impurities lossis additives.Ntawm qhov tod tes, kev deev luag poj luag txiv cellulose muaj lwm yam tshuaj, uas tej zaum yuav yog lwm yam khoom uas txhob txwm los yog tsis txhob txwm ua rau lawv zoo thiab cov yam ntxwv.
2. Cov yam ntxwv ntawm lub cev: Ntshiab HPMC yog ib hom hmoov dawb, tsis qab ntsev, soluble hauv dej los tsim cov kua nplaum pob tshab.Kev deev luag poj luag txiv HPMC tej zaum yuav muaj cov yam ntxwv ntawm lub cev sib txawv, nyob ntawm seb hom thiab ntau npaum li cas ntawm tus neeg deev deev ntxiv.Kev nkag tuaj yeem cuam tshuam rau solubility, viscosity thiab xim ntawm cov khoom.
3. Cov yam ntxwv tshuaj: Pure HPMC yog cov ntshiab ntshiab polymer nrog cov yam ntxwv ntawm cov tshuaj zoo ib yam.Kev nkag mus rau lwm cov ntaub ntawv tuaj yeem hloov pauv cov yam ntxwv ntawm HPMC, uas cuam tshuam rau nws txoj haujlwm thiab kev ruaj ntseg.
4. Kev nyab xeeb: Kev siv cov tshuaj tua kab mob cellulose tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv vim tias kev deev luag poj luag txiv no yuav muaj cov tshuaj lom lossis ua rau muaj kev phom sij.Kev deev luag poj luag txiv HPMC kuj tseem tuaj yeem cuam tshuam nrog lwm yam khoom hauv txoj kev tsis tuaj yeem, uas ua rau muaj teeb meem loj.
5. Tus nqi: Adapted cellulose yog pheej yig dua li HPMC ntshiab, vim tias qhov sib ntxiv ntawm cov tshuaj doping yuav txo cov nqi tsim khoom.Txawm li cas los xij, kev siv kev deev luag poj luag txiv HPMC hauv kev tsim tshuaj lossis lwm yam khoom yuav ua rau qhov zoo thiab kev ua tau zoo ntawm cov khoom.
Tag nrho hauv tag nrho, ntshiab HPMC yog cov ntshiab ntshiab thiab muaj kev nyab xeeb polymer, nrog cov tshuaj lom neeg thiab lub cev zoo ib yam.Kev ua phem rau lwm yam tshuaj tuaj yeem hloov pauv tus yam ntxwv ntawm HPMC, yog li ua rau qhov zoo thiab kev nyab xeeb ntawm cov khoom puas.Yog li, HPMC ntshiab yuav tsum tau siv rau hauv kev tsim tshuaj, khoom noj, tsev thiab lwm yam khoom.
