Dab tsi yog qhov cuam tshuam uas cuam tshuam rau kev coj dawb huv ntawm hydroxypropyl methylulose?

Lub purity ntawm hydroxypropylulose hauv tsev thermal rwb thaiv tsev kev sib xyaw, yog li dab tsi yog qhov yog dab tsi yog qhov tseeb ntawm hydroxyprropylulose? Pab koj teb cov lus nug no hnub no.

Hauv cov txheej txheem ntau lawm ntawm hydroxypropylulose, qhov tseem ceeb oxygen yuav txwv, ntev li cov lwg me me tau rov qab ua dua, nws tsis yog qhov nyuaj heev. Kev puas tsuaj. Cov dej tseem ceeb tshaj plaws muaj ntau yam yuav tau ua nrog cov ntsiab lus ntawm hydroxypropyl. Qee cov Hoobkas cia tsuas yog xav kom txo tus nqi thiab tus nqi, thiab tsis kam nce cov ntsiab lus ntawm hydroxypropyl, yog li tsis tuaj yeem ncav rau theem ntawm cov khoom lag luam txawv teb chaws.

Cov dej tswj hwm ntawm hydroxypropylulose kuj tseem muaj kev sib raug zoo, thiab rau tag nrho cov txheej txheem kev txiav txim siab, thiab rau cov dej tsis sib haum xeeb ntawm hydroxypropylulose. Cov nyhuv ntawm alkalizing, piv ntawm methyl chloride rau propylene oxide, kev sib piv ntawm cov dej alkali thiab cov piv txwv ntawm cov zaub mov ua kom zoo txhua yam kev txiav txim siab ntawm cov khoom.

Qhov zoo ntawm cov ntaub ntawv raw, cov nyhuv ntawm alkalizing, kev tswj hwm ntawm cov kuab tshuaj, nws yog milloxyprcellulose, thiab qee qhov daj, thiab ib txhia yog qhov tseeb thiab pob tshab. Txhawm rau daws nws, kho los ntawm cov ntsiab lus saum toj no. Qee lub sij hawm acetic acid tuaj yeem cuam tshuam rau lub teeb kev hloov pauv. Nws yog qhov zoo tshaj plaws los siv acetic acid tom qab dmutioning. Qhov cuam tshuam loj tshaj plaws yog seb cov kev sib tw ntawm cov tshuaj tiv thaiv yog qhov ruaj khov thiab tsis ruaj khov (qee cov ntaub ntawv muaj cov kuab tshuaj uas tsis khov, xws li cov kuab tshuaj siv rau kev rov ua dua tshiab). Ntau yam yog nyob ntawm kev ua si. Cov khoom siv ruaj khov ntawm cov khoom siv thiab kev ua haujlwm ntawm cov neeg ua haujlwm zoo yuav tsum tsim cov khoom lag luam ruaj khov. Qhov kev hloov chaw kaj yuav tsis pub tshaj qhov ntau ntawm ± 2%, thiab cov chaw hloov chaw ntawm cov pab pawg hloov pauv tau zoo. Hloov chaw ntawm cov khaub ncaws tsis zoo, kev hloov pauv yuav twv yuav raug zoo.

Yog li ntawd, cov khoom lag luam zoo yog txiav txim siab los ntawm cov ntaub ntawv raw, cov cuab yeej ntau lawm, thiab lwm yam. Tsuas yog los ntawm nruj me ntsis tswj hwm los ntawm ib qho mus rau qhov kawg tuaj yeem tsim nrog cov khoom ruaj khov zoo.
