Dab tsi yog cov txiaj ntsig ntawm kev siv hydroxypropylencellulose li hollow ntsiav tshuaj?

Cov khoom no yog 2-hydroxypropyl etherheth methyl cellulose, uas yog ib qho khoom lag luam sighthetic. Nws tuaj yeem tsim los ntawm ob txoj kev: (1) Tom qab kho cov paj rwb los yog ntoo pulp fibers nrog chlorometiatane thiab epoxy propane thiab ua kom zoo thiab pulverized kom tau nws; (2) Siv cov qib methyl tsim nyog los kho nrog cov sodium hydroxide, hnov ​​mob nrog epylene oxide thiab siab rau qib zoo, thiab rov ua kom zoo nkauj. Lub cev hnyav dua li ntawm 10,000 txog 1,500,000.

★ Cov tswvyim ntshiab ntshiab, txhim kho kev zom zaub mov thiab nqus tau.

★ Cov dej dej qis cov ntsiab lus, 5% -8%. Muaj zog noo noo kev tiv thaiv kev tiv thaiv, cov ntsiab lus tsis yooj yim rau agglomerate, thiab cov tshuaj ntsiav hniav tsis yooj yim rau deform, ua nkig, thiab tawv.

Tsis muaj kev pheej hmoo ntawm cross-sib txuas, tsis muaj kev sib cuam tshuam, muaj kev pheej hmoo ntawm cov tshuaj tiv thaiv cov protein ntau hauv gelatin.

Cov yuav tsum muaj rau cov xwm txheej cia:

Nws yuav luag tsis tawg hauv qhov chaw noo nyob hauv ib puag ncig qis, muaj kev ruaj khov zoo thaum muaj kub, thiab cov tshuaj ntsiav tsis deform.

★ cov qauv niaj hnub ua tau zoo thiab kev sib raug zoo:

Muaj feem rau cov qauv siv hluav taws xob, cov duab, qhov loj me, cov qauv thiab tsis tas yuav hloov cov khoom thiab seem.

★ cov tsiaj uas tsis muaj kev pheej hmoo, tsis muaj peev xwm muaj feem cuam tshuam ntawm kev loj hlob hormones lossis tshuaj tso sab laug hauv cov tsiaj lub cev.

HydroxyPropyyl MethylcelluloseCov ntsiav tshuaj khoob yog txawv ntawm cov tsoos gelatin npluav tsiav tshuaj. Lawv yog hydroxypropy kas methylcellulose (HPMC) ua los ntawm cov ntoo pulp. Ntxiv nrog rau qhov zoo ntawm cov ntshiab ntuj lub tswv yim, hydroxyprropyl ntawm cov tshuaj pleev ib ce thiab cov yam ntxwv uas muaj cov tshuaj pleev pob txha tsis muaj. Nrog kev paub txuas ntxiv ntawm tib neeg txoj kev saib xyuas tus kheej, kev ua neeg tsis muaj kev ntseeg, thiab lwm yam kev ntseeg ko taw thiab lwm yam, thiab cov khoom noj hniav dawb huv yuav dhau los ua cov kev coj ua rau kev tsim kho tshuaj ntsiav.
