Hydroxypropylmethylcellulose (HPMC) yog cellulose derivative feem ntau siv nyob rau hauv ntau yam lag luam niaj hnub no.Nws yog tsuas yog siv los ua thickener, nplaum thiab stabilizer hauv cov khoom noj, tshuaj thiab tshuaj pleev ib ce industries.Nws yog qhov zoo dua li lwm cov kev xaiv vim nws yooj yim siv, nyab xeeb thiab tsis muaj tshuaj lom.Txawm li cas los xij, ib qho tseem ceeb ntawm cov tshuaj no yog nws cov hmoov tshauv.
Cov hmoov tshauv ntawm HPMC yog qhov tseem ceeb hauv kev txiav txim siab nws qhov zoo thiab purity.Cov ntsiab lus tshauv yog hais txog cov ntxhia thiab cov ntaub ntawv tsis muaj sia nyob hauv cellulose derivative.Cov zaub mov no tuaj yeem muaj me me lossis loj, nyob ntawm qhov chaw thiab qhov zoo ntawm HPMC.
Cov ntsiab lus tshauv tuaj yeem txiav txim siab los ntawm kev hlawv ib qho tshwj xeeb ntawm HPMC ntawm qhov kub thiab txias kom tshem tawm tag nrho cov khoom siv organic, tsuas yog cov seem uas tsis muaj organic.Cov hmoov tshauv ntawm HPMC yuav tsum nyob rau hauv ib qho kev pom zoo kom tsis txhob muaj kev sib kis thiab xyuas kom meej tias nws lub cev thiab tshuaj lom neeg tsis cuam tshuam.
Cov hmoov tshauv tau txais ntawm HPMC sib txawv raws li kev lag luam uas nws siv.Piv txwv li, kev lag luam khoom noj muaj cov kev cai nruj ntawm cov hmoov tshauv siab tshaj plaws uas tau tso cai hauv HPMC.Cov hmoov tshauv ntawm cov zaub mov qib HPMC yuav tsum tsawg dua 1%.Tib neeg noj ib yam khoom siab tshaj qhov txwv no ua rau muaj kev pheej hmoo rau kev noj qab haus huv.Yog li ntawd, nws yog ib qho tseem ceeb los xyuas kom meej tias cov zaub mov qib HPMC muaj cov hmoov tshauv raug.
Ib yam li ntawd, kev lag luam kws tshuaj muaj cov kev cai ntawm cov hmoov tshauv ntawm HPMC.Cov hmoov tshauv tso cai yuav tsum tsawg dua 5%.Txhua HPMC siv hauv kev lag luam yuav tsum yog qhov tseeb purity lossis zoo kom tsis txhob muaj kab mob.
Cov tuam txhab tshuaj pleev ib ce kuj xav tau HPMC zoo nrog cov ntsiab lus tshauv tsim nyog.Qhov no yog vim tias cov hmoov tshauv ntau dhau hauv HPMC tuaj yeem cuam tshuam nrog lwm cov khoom xyaw hauv cov tshuaj pleev ib ce, ua rau muaj kev phom sij rau lub cev thiab tshuaj lom neeg ntawm daim tawv nqaij.
Cov hmoov tshauv ntawm HPMC yuav tsum nyob rau hauv cov kev txwv uas siv tau rau txhua qhov kev lag luam uas nws siv.Txawm li cas los xij, nws tsis txaus los txiav txim qhov zoo ntawm HPMC nkaus xwb los ntawm cov ntsiab lus tshauv.Lwm yam xws li viscosity, pH thiab noo noo cov ntsiab lus kuj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws qhov zoo tag nrho.
HPMC nrog cov ntsiab lus tshauv yog muaj ntau yam zoo.Nws ua kom cov khoom purity thiab zoo, txo qhov kev pheej hmoo ntawm kev sib kis thiab txhim kho cov khoom muaj kev ruaj ntseg.Qhov no ua rau nws yooj yim dua rau cov tuam ntxhab kom ua tau raws li cov qauv kev cai rau txhua qhov kev lag luam.
Cov hmoov tshauv ntawm hydroxypropyl methylcellulose yog ib qho tseem ceeb los xyuas kom meej cov khoom zoo thiab kev nyab xeeb.Xyuas kom meej tias HPMC muaj cov hmoov tshauv raug rau txhua qhov kev lag luam ntawm kev siv yog qhov tseem ceeb.Cov neeg tsim khoom kuj tseem yuav tsum siv cov HPMCs zoo ntawm qhov tsim nyog purity thiab xyuas kom lawv ua tau raws li cov qauv kev lag luam.Nrog rau cov ntsiab lus tshauv zoo, HPMC yuav txuas ntxiv ua cov khoom tseem ceeb hauv ntau qhov kev lag luam.
