Hydroxypropyl Methylcellulose (HPMC)yog ib qho cellulose derivative uas siv dav hauv dej uas yaj tau zoo, ua rau zaj duab xis zoo, ua rau tuab, thiab lwm yam. Nws siv dav hauv tshuaj, khoom noj, tshuaj pleev ib ce thiab cov ntaub ntawv siv hauv tsev. Txawm li cas los xij, yog tias KimaCell®HPMC tsis siv kom raug, nws yuav ua rau muaj qee qhov tsis zoo, tshwj xeeb tshaj yog hauv kev npaj tshuaj, cov khoom noj khoom haus ntxiv thiab cov ntawv thov hauv kev lag luam. Kev siv tsis raug yuav tsis tsuas yog cuam tshuam rau qhov zoo thiab kev ua tau zoo ntawm cov khoom, tab sis kuj tseem yuav ua rau muaj kev puas tsuaj rau tib neeg kev noj qab haus huv.
1. Kev cuam tshuam rau kev npaj tshuaj
Hauv kev npaj tshuaj, HPMC feem ntau yog siv los ua cov khoom ua kom tuab, cov neeg sawv cev gelling lossis cov neeg sawv cev tso tawm tas mus li, tshwj xeeb tshaj yog rau cov ntsiav tshuaj, tshuaj ntsiav, cov tshuaj noj thiab cov tshuaj pleev. Txawm li cas los xij, yog tias nws tsis siv kom raug, nws yuav ua rau muaj teeb meem hauv qab no:
a. Cov nyhuv tso tawm tsis zoo
HPMC feem ntau ua haujlwm ua tus neeg sawv cev tso tawm tas mus li hauv cov tshuaj tso tawm tas mus li. Nws cov txiaj ntsig tso tawm tas mus li feem ntau nyob ntawm nws cov txheej txheem o thiab yaj hauv dej. Yog tias qhov ntau ntawm HPMC ntau dhau lossis tsawg dhau, tus nqi ntawm kev tso tawm tshuaj yuav tsis tswj tau, yog li cuam tshuam rau qhov ua tau zoo. Piv txwv li, kev siv HPMC ntau dhau yuav ua rau cov tshuaj tso tawm qeeb dhau, ua rau muaj cov txiaj ntsig kho mob tsis tseem ceeb; ntawm qhov tod tes, kev siv tsawg dhau yuav ua rau cov tshuaj tso tawm sai dhau, ua rau muaj kev phiv ntau ntxiv lossis txo qhov ua tau zoo.
b. Kev ruaj khov ntawm cov tshuaj tsis zoo
Yog tias qhov concentration ntawm HPMC tsis txaus, nws yuav cuam tshuam rau qhov ruaj khov ntawm cov tshuaj. Yog tias qhov concentration siab dhau, qhov fluidity ntawm cov tshuaj yuav poob qis, cuam tshuam rau kev ua haujlwm ntawm cov tshuaj, ua rau cov ntsiav tshuaj tawg, deform lossis nyuaj rau nias. Yog tias qhov concentration qis dhau, qhov thickening effect yuav tsis ua tiav, ua rau cov tshuaj yaj tsis sib npaug lossis tsis tiav, cuam tshuam rau qhov ua tau zoo.
c. Kev ua xua
Txawm hais tias HPMC feem ntau suav tias muaj kev nyab xeeb, qee qhov xwm txheej tshwj xeeb, qee tus neeg mob yuav muaj kev tsis haum tshuaj rau nws, ua rau muaj cov tsos mob xws li tawv nqaij liab, o, thiab khaus. Yog tias qhov ntau ntawm HPMC hauv cov tshuaj ntau dhau, qhov kev pheej hmoo ntawm kev tsis haum tshuaj yuav nce ntxiv.
2. Kev cuam tshuam rau zaub mov
Hauv cov khoom noj, HPMC feem ntau yog siv los ua cov khoom ua kom tuab, emulsifier thiab stabilizer. Kev siv ntau dhau lossis tsis raug yuav ua rau cov khoom noj tsis zoo thiab txawm tias cuam tshuam rau tib neeg kev noj qab haus huv.
a. Cuam tshuam rau saj ntawm cov khoom noj
Thaum siv HPMC rau hauv cov khoom noj, yog tias qhov ntau ntxiv ntau dhau, cov khoom noj yuav dhau los ua viscous thiab cuam tshuam rau qhov saj ntawm cov khoom noj. Rau qee cov khoom noj uas xav tau qhov saj tshiab, xws li kua txiv hmab txiv ntoo lossis dej qab zib, siv HPMC ntau dhau yuav ua rau cov qauv tuab dhau thiab poob nws qhov kev xav tshiab.
b. Teeb meem zom zaub mov
Ua ib hom fiber ntau hauv kev noj haus, KimaCell®HPMC cov yam ntxwv nthuav dav hauv txoj hnyuv yuav ua rau mob plab hnyuv, tshwj xeeb tshaj yog thaum noj ntau dhau. Kev noj ntau dhau ntawm HPMC mus sij hawm ntev yuav ua rau muaj teeb meem ntawm lub plab zom mov xws li flatulence, cem quav lossis raws plab. Tshwj xeeb tshaj yog rau cov neeg uas muaj kev ua haujlwm tsis zoo ntawm txoj hnyuv, HPMC ntau dhau yuav ua rau cov teeb meem no hnyav dua.
c. Kev nqus cov as-ham tsawg
Ua ib yam fiber uas yaj tau hauv dej, HPMC muaj txiaj ntsig zoo rau kev noj qab haus huv ntawm txoj hnyuv thaum noj kom tsawg, tab sis kev siv ntau dhau yuav ua rau muaj kev cuam tshuam rau kev nqus cov as-ham. Kev noj zaub mov ntau dhau yuav cuam tshuam rau kev nqus cov zaub mov thiab cov vitamins hauv txoj hnyuv, tshwj xeeb tshaj yog cov zaub mov xws li calcium thiab hlau. Yog li ntawd, thaum ntxiv HPMC rau hauv zaub mov, nws cov nyiaj yuav tsum tau tswj hwm kom tsis txhob siv ntau dhau.
3. Kev cuam tshuam rau cov tshuaj pleev ib ce
Hauv cov tshuaj pleev ib ce, HPMC feem ntau yog siv ua cov khoom ua kom tuab, stabilizer thiab emulsifier. Kev siv tsis raug yuav muaj kev cuam tshuam tsis zoo rau cov nyhuv ntawm cov khoom.
a. Cov qauv khoom tsis zoo
Yog tias siv HPMC ntau dhau, cov tshuaj pleev ib ce yuav dhau los ua nplaum dhau, nyuaj rau siv, thiab txawm tias cuam tshuam rau tus neeg siv kev paub. Ntawm qhov tsis sib xws, siv tsawg dhau yuav tsis muab cov nplaum txaus, ua rau cov khoom xws li tshuaj pleev kom yooj yim faib ua pawg, cuam tshuam rau kev ruaj khov thiab kev paub siv.
b. Kev khaus tawv nqaij
Txawm hais tias HPMC feem ntau suav tias muaj kev nyab xeeb, rau cov neeg uas muaj daim tawv nqaij rhiab heev, kev siv ntau dhau yuav ua rau muaj qee qhov kev tsis haum, xws li daim tawv nqaij qhuav, nruj lossis liab, tshwj xeeb tshaj yog cov khoom xws li lub ntsej muag lub ntsej muag uas muaj kev sib cuag ntev nrog daim tawv nqaij.
4. Kev cuam tshuam rau cov ntaub ntawv siv hauv tsev
Hauv kev tsim kho, HPMC feem ntau yog siv ua cov khoom ua kom tuab, khaws dej, thiab ntxiv rau kev txhim kho kev ua haujlwm ntawm kev tsim kho. Yog tias HPMC tsis siv kom raug, cov teeb meem hauv qab no yuav tshwm sim:
a. Kev puas tsuaj ntawm kev ua haujlwm ntawm kev tsim kho
HPMC ua lub luag haujlwm hauv kev txhim kho kev ua haujlwm ntawm cov ntaub ntawv siv hauv kev tsim kho xws li cov cement slurry thiab mortar, xws li kev txhim kho nws txoj kev ua haujlwm thiab kev ntws. Yog tias siv ntau dhau, cov khoom sib xyaw yuav dhau los ua viscous dhau, ua rau muaj teeb meem hauv kev tsim kho thiab kev ua haujlwm tsis zoo; yog tias siv tsis txaus, cov khoom siv hauv kev tsim kho yuav tsis zoo dua, cuam tshuam rau qhov zoo ntawm kev tsim kho.
b. Kev cuam tshuam rau lub zog ntawm cov khoom siv
Qhov ntxiv ntawm KimaCell®HPMC tuaj yeem txhim kho lub zog thiab kev nplaum ntawm cov ntaub ntawv tsim kho, tab sis yog tias siv tsis raug, nws yuav cuam tshuam rau qhov kawg hardening effect. Yog tias qhov ntau ntawm HPMC loj dhau, nws yuav cuam tshuam rau qhov hydration reaction ntawm cement slurry, ua rau lub zog ntawm cov khoom siv txo qis, yog li cuam tshuam rau kev nyab xeeb thiab kev ruaj khov ntawm lub tsev.
Txawm hais tias hydroxypropyl methylcellulose siv dav hauv ntau lub lag luam thiab muaj ntau yam khoom zoo heev, kev siv tsis raug yuav muaj kev cuam tshuam tsis zoo rau cov khoom zoo, kev noj qab haus huv tib neeg thiab kev siv cov teebmeem. Yog li ntawd, thaum sivHPMC, nws yuav tsum tau ua raws li tus qauv thiab cov koob tshuaj pom zoo, zam kev siv ntau dhau lossis tsis raug cai kom ntseeg tau tias nws cov txiaj ntsig zoo tshaj plaws thiab zam kev tshwm sim tsis zoo.
