Txheej txheem cej luam ntawm Cellulose ether
Cellulose ether yog ib hom polysaccharide uas tau los ntawm cellulose, ib txwm tshwm sim polysaccharide pom hauv cov nroj tsuag. Cellulose ethers yog siv nyob rau hauv ntau yam kev lag luam, xws li tshuaj, khoom noj khoom haus, tshuaj pleev ib ce, thiab kev tsim kho. Cellulose ethers yog polymers uas yog tsim los ntawm rov qab units ntawm qabzib, uas yog txuas ua ke los ntawm ether linkages. Cov kev sib txuas no yog tsim thaum cov pa atom tso rau ntawm ob lub pa roj carbon atom hauv cov piam thaj molecule. Cellulose ethers tau siv ntau yam kev siv vim lawv cov khoom tshwj xeeb. Lawv yog cov heev soluble nyob rau hauv dej, ua rau lawv zoo tagnrho rau siv nyob rau hauv aqueous daws. Lawv kuj tsis muaj tshuaj lom thiab tsis ua rau khaus, ua rau lawv muaj kev nyab xeeb rau kev siv hauv cov khoom noj thiab tshuaj pleev ib ce. Cellulose ethers kuj muaj kuab heev, ua rau lawv zoo tagnrho rau siv ua thickeners thiab stabilizers nyob rau hauv ntau yam khoom. Cellulose ethers muaj nyob rau hauv ntau hom, xws li methylcellulose, hydroxyethylcellulose, thiab carboxymethylcellulose. Txhua hom cellulose ether muaj nws cov khoom tshwj xeeb thiab tuaj yeem siv rau kev siv sib txawv. Methylcellulose yog cov hmoov dawb uas siv los ua cov thickener, emulsifier, thiab stabilizer hauv cov khoom noj. Hydroxyethylcellulose yog cov hmoov dawb uas siv los ua cov thickener, stabilizer, thiab tshem tawm tus neeg sawv cev hauv cov chaw muag tshuaj thiab tshuaj pleev ib ce. Carboxymethylcellulose yog cov hmoov dawb uas siv los ua cov thickener, emulsifier, thiab stabilizer hauv cov khoom noj. Cellulose ethers kuj tseem siv rau hauv kev tsim kho. Lawv yog siv los ua binders hauv cement thiab plaster, nrog rau kev tsim cov nplaum thiab sealants. Cellulose ethers kuj tseem siv rau hauv kev tsim cov xim thiab coatings, nrog rau kev tsim cov ntawv thiab cov duab los qhia. Cellulose ethers kuj tseem siv rau hauv kev kho mob. Lawv siv los ua cov thickener thiab stabilizer hauv ntau yam khoom siv tshuaj, suav nrog cov tshuaj pleev, tshuaj pleev, thiab tshuaj pleev. Lawv kuj tau siv los ua tus neeg sawv cev ncua hauv qhov muag tee thiab tshuaj tsuag qhov ntswg. Cellulose ethers kuj tseem siv rau hauv kev lag luam tshuaj pleev ib ce. Lawv yog siv los ua cov thickener, emulsifier, thiab stabilizer nyob rau hauv ntau yam khoom, xws li cream, lotions, thiab pleev. Lawv kuj tau siv los ua tus neeg sawv cev ncua hauv cov naj hoom thiab colognes. Cellulose ethers kuj tseem siv rau hauv kev lag luam textile. Lawv yog siv los ua cov thickener, emulsifier, thiab stabilizer nyob rau hauv ntau yam khoom, nrog rau cov xim, dyes, thiab adhesives. Lawv kuj tau siv los ua tus neeg sawv cev ncua hauv cov ntaub softeners thiab detergents. Cellulose ethers kuj tseem siv rau hauv kev lag luam khoom noj. Lawv yog siv los ua cov thickener, emulsifier, thiab stabilizer nyob rau hauv ntau yam khoom, nrog rau cov kua ntses, hnav khaub ncaws, thiab khoom qab zib. Lawv kuj tau siv los ua tus neeg sawv cev ncua hauv dej haus thiab dej khov. Cellulose ethers yog cov khoom siv ntau yam thiab muaj txiaj ntsig uas tuaj yeem siv rau ntau yam kev lag luam. Lawv tsis muaj tshuaj lom thiab tsis ua rau khaus, ua rau lawv muaj kev nyab xeeb rau kev siv khoom noj thiab tshuaj pleev ib ce. Lawv kuj yog cov soluble heev hauv dej, ua rau lawv zoo tagnrho rau kev siv hauv aqueous daws. Lawv kuj yog cov viscous heev, ua rau lawv zoo tagnrho rau kev siv cov thickeners thiab stabilizers hauv ntau yam khoom.
