Methylcellulose yog ib hom cellulose derivative dav siv hauv tshuaj, khoom noj khoom haus thiab kev lag luam. Nws yog cov dej-soluble polymer feem ntau yog ua los ntawm cov nroj tsuag ntuj cellulose los ntawm kev hloov kho tshuaj, thiab muaj ntau yam khoom tshwj xeeb, xws li thickening, gelling, ncua kev kawm ntawv, film-forming thiab dej tuav.
Cov yam ntxwv thiab kev siv ntawm methylcellulose
Thickener thiab gelling tus neeg sawv cev: Hauv kev lag luam khoom noj khoom haus, methylcellulose feem ntau yog siv los ua cov thickener thiab gelling tus neeg saib xyuas los pab txhim kho kev ntxhib los mos thiab saj ntawm cov khoom. Piv txwv li, nyob rau hauv cov khoom xws li ice cream, jam thiab zaub xam lav hnav khaub ncaws, methylcellulose tuaj yeem muab cov viscosity zoo thiab txhim kho kev ruaj ntseg ntawm cov khoom.
Cov neeg nqa tshuaj thiab excipients: Hauv kev lag luam kws tshuaj, methylcellulose feem ntau yog siv los ua cov khoom siv tshuaj, xws li cov ntawv khi thiab muab tub lim rau cov ntsiav tshuaj. Nws tseem tuaj yeem siv los ua cov tshuaj tiv thaiv-tso tawm tus neeg saib xyuas los tswj qhov tso tawm ntawm cov tshuaj thiab ua kom muaj kev ruaj ntseg thiab ua haujlwm ntev ntawm cov tshuaj.
Daim ntawv thov hauv cov ntaub ntawv hauv tsev: Hauv kev tsim cov khoom siv hauv tsev, methylcellulose yog siv los ua cov thickener thiab dej-retaining tus neeg sawv cev hauv cov cement, gypsum thiab coatings los txhim kho kev tsim kho thiab ua haujlwm ntawm cov khoom.
Qhov sib txawv ntawm methylcellulose thiab antifoaming agents
Antifoaming agents yog ib chav kawm ntawm cov tshuaj siv los tua lossis tshem tawm cov npuas hauv cov kua, thiab feem ntau pom muaj nyob rau hauv kev ua zaub mov, tshuaj, tshuaj pleev ib ce, papermaking, tshuaj, thiab kev kho dej. Antifoaming cov neeg ua haujlwm feem ntau ua haujlwm los ntawm kev txo qhov nro ntawm cov kua los tiv thaiv kev tsim ua npuas ncauj, los yog los ntawm kev txhawb nqa lub cev qhuav dej ntawm cov npuas. Cov tshuaj tiv thaiv kab mob feem ntau suav nrog cov roj silicone, polyethers, fatty acid esters, thiab qee yam khoom, xws li silicon dioxide.
Txawm li cas los xij, methylcellulose tsis yog cov tshuaj tua kab mob hauv qhov xwm txheej. Txawm hais tias methylcellulose tuaj yeem tsim cov kua dej khov thaum yaj hauv dej, thiab cov viscosity ntawm cov tshuaj no tuaj yeem cuam tshuam rau kev tsim cov npuas dej hauv qee qhov, nws tsis muaj cov khoom ua haujlwm ntawm cov tshuaj tiv thaiv kab mob. Hauv lwm lo lus, lub luag haujlwm tseem ceeb ntawm methylcellulose yog tias nws ua cov thickener, gelling tus neeg sawv cev, tshem tawm tus neeg sawv cev, thiab lwm yam, tsis yog siv tshwj xeeb los tua lossis tshem tawm ua npuas ncauj.
Muaj tsis meej pem thiab tshwj xeeb
Txawm hais tias methylcellulose tsis yog tus neeg sawv cev antifoaming, hauv qee cov qauv tsim lossis cov khoom lag luam, nws tuaj yeem cuam tshuam ncaj qha rau tus cwj pwm ntawm npuas vim nws cov nyhuv thickening thiab cov yam ntxwv ntawm kev daws. Piv txwv li, nyob rau hauv ib co zaub mov los yog tshuaj formulations, lub siab viscosity ntawm methylcellulose yuav txwv tsis pub tsim npuas los yog ua rau cov npuas uas tau tsim kom dissipate sai dua. Txawm li cas los xij, cov nyhuv no tsis tso cai rau nws muab cais ua tus neeg sawv cev antifoaming vim tias nws cov txheej txheem tseem ceeb ntawm kev ua haujlwm yog qhov sib txawv ntawm cov tshuaj lom neeg thiab cov txheej txheem ntawm kev ua ntawm cov tshuaj tua kab mob.
Methylcellulose yog ib qho siv dav hauv cellulose derivative nrog ntau lub zog, tab sis nws tsis suav tias yog tus neeg sawv cev antifoaming. Txawm hais tias nws yuav muaj kev cuam tshuam rau tus cwj pwm foaming hauv qee qhov xwm txheej, qhov no tsis yog nws qhov kev siv tseem ceeb lossis kev ua haujlwm. Antifoaming cov neeg ua haujlwm feem ntau muaj cov haujlwm tshwj xeeb thiab ua npuas dej tswj lub peev xwm, thaum methylcellulose siv ntau dua rau thickening, gelling, suspension thiab dej tuav. Yog li ntawd, thaum thov methylcellulose, yog hais tias yuav tsum tau ib tug ntshiab antifoaming nyhuv, ib tug tshwj xeeb antifoaming tus neeg saib xyuas yuav tsum tau xaiv rau siv nyob rau hauv ua ke nrog.
