Dab tsi yog cov ntawv thov tseem ceeb ntawm hydroxypropyl methylcellulose thiab methylcellulose?

HydroxyPropyyl methylulose (HPMC) thiab methylcellulose (MC) yog ob lub cellulose derivatives dav siv nyob rau hauv ntau daim teb. Lawv txawv hauv cov qauv tshuaj thiab yog li ntawd hauv daim ntawv thov.

HydroxyPropyyl Methylcellulose (HPMC)

1. Lub tsev ua haujlwm
HPMC yog dav siv hauv cov ntaub ntawv hauv tsev, feem ntau yog cov dej so thiab hloov kho hauv cov xis xis, gypsum khoom thiab cov vuas nplaum nplaum. Nws tuaj yeem txhim kho kev ua haujlwm, tiv thaiv kev tawg, ua kom muaj zog ntxiv, thiab txhim kho cov khoom siv hauv dej thiab tsim cov khoom siv.

2. Tshuaj thiab Tshuaj pleev ib ce

Nws yog lub luag haujlwm tseem ceeb hauv cov khoom noj muaj calorie tsawg thiab cov khoom noj kom zoo dua qub, thiab txhim kho cov khoom noj, thiab txhim kho cov khoom noj tshiab thiab ua kom cov khoom noj tshiab.

4. Lwm cov ntawv thov
HPMC kuj tseem siv rau hauv cov tsho tiv no, inks, ntawv, ua liaj / teb, textiles thiab lwm daim teb. Nyob rau hauv cov tsho tuab, nws ua raws li cov tuab thiab khov kho thiab tsis khov kho kom zoo thiab tawg ntawm cov txheej txheem. Hauv kev ua liaj ua teb

Methylcellulose (MC)

1. Lub tsev ua haujlwm
Daim ntawv thov ntawm MC hauv cov ntaub ntawv tsim tsev zoo ib yam li HPMC, tsuas yog siv los ua cov tshuaj cug fickener thiab dej-cug, gypsum khoom thiab pobzeb cov nplaum. Nws tuaj yeem txhim kho kev tsim kho thiab txhim kho cov dej khaws cia thiab ua kom lub zog ntawm cov khoom siv.

2. Tshuaj thiab Tshuaj pleev ib ce
Hauv cov chaw muag tshuaj, MC tau siv los ua tus neeg sawv cev tsis sib haum thiab muaj cov ntsiav tshuaj tawm los rau cov tshuaj siv tshuaj, nrog rau cov tuab tuab ntawm qhov muag poob. Hauv cov tshuaj pleev ib ce, MC tau siv los ua cov tuab thiab muaj stabilizer hauv cov khoom saib xyuas cov khoom, tshuaj pleev thiab tshuaj zawv plaub hau.

3. Kev lag luam khoom noj khoom haus
Daim ntawv thov ntawm MC hauv kev lag luam khoom noj yog feem ntau muaj nyob rau hauv thickening, emulsification thiab stabilization. Nws yog siv hauv cov mis nyuj khov, jelly, jam thiab ci khoom los txhim kho cov saj thiab kev ntxhib los mos khaws cia, thiab txhim kho cov dej khaws cia thiab cov khoom noj tshiab.

4. Lwm cov ntawv thov
MC tseem muaj dav siv rau hauv cov tsho tiv no, inks, ntawv, textiles thiab kev ua liaj ua teb. Hauv cov txheej txheej, nws yog siv los ua cov tuab thiab khov kho kom zoo dua los txhim kho kom zoo thiab tawg ntawm txheej. Nyob rau hauv kev ua liaj ua teb, MC tau siv nyob rau hauv kev tso tawm-tso tawm kev npaj tshuaj tua kab thiab cov chiv los txhim kho cov tshuaj thiab cov chiv.

Txawm hais tias hydroxypropal methylcellose (HPMC) thiab methylcellulose (MC) yog ob tus kheej cov haujlwm tshwj xeeb hauv cov teb sib txawv. HPMC tau siv dav hauv cov ntaub ntawv hauv tsev, tshuaj, tshuaj pleev ib ce vim nws cov tuab heev, dej tuav thiab ruaj khov. MC kuj muaj cov ntawv thov ua vaj tsev, tshuaj, tshuaj pleev ib ce thiab zaub mov zoo vim nws cov khoom siv huv. Tsis tas li ntawd, cov ob txhais ob leeg derivges tseem dav siv rau hauv cov txheej txheem, inks, ntawv, textiles thiab kev ua liaj ua teb. Lawv daim ntawv thov tsis tsuas yog txhim kho cov khoom lag luam thiab qhov zoo, tab sis kuj tseem nce ntau lawm kev ua tau zoo thiab nyiaj txiag.
