Taw qhia

Cellulose ethers yog ib hom dej-soluble polymer uas tau siv ntau yam kev siv, suav nrog pob zeb. Cellulose ethers yog siv los txhim kho kev ua haujlwm, lub zog, thiab ua haujlwm ntev ntawm pob zeb. Lawv kuj tseem siv los txo cov dej permeability, txhim kho adhesion, thiab txo qis shrinkage. Cellulose ethers feem ntau yog ntxiv rau pob zeb hauv daim ntawv ntawm cov kua nplaum los yog hmoov. Daim ntawv no tshuaj xyuas kev siv cellulose ethers hauv pob zeb thiab nws cov teebmeem ntawm cov khoom ntawm pob zeb.

Hom Cellulose Ethers

Cellulose ethers tau muab faib ua ob pawg loj: hydroxyethylcellulose (HEC) thiab hydroxypropylcellulose (HPC). HEC yog ib qho uas tsis yog-ionic cellulose ether uas yog siv rau hauv pob zeb los txhim kho kev ua haujlwm, txo cov dej permeability, thiab txo qhov shrinkage. HPC yog anionic cellulose ether uas yog siv los txhim kho adhesion thiab txo cov dej permeability.

Qhov cuam tshuam rau cov khoom vaj khoom tsev

Kev siv cov cellulose ethers hauv pob zeb tuaj yeem muaj txiaj ntsig zoo rau cov khoom ntawm pob zeb. Cellulose ethers tuaj yeem txhim kho kev ua haujlwm ntawm pob zeb los ntawm kev ua kom cov dej ntws ntawm cov pob zeb sib xyaw. Qhov no tuaj yeem txo cov dej xav tau kom ua tiav qhov kev xav tau ua haujlwm. Cellulose ethers kuj tseem tuaj yeem txo cov dej permeability thiab shrinkage, uas tuaj yeem txhim kho qhov ruaj khov ntawm pob zeb. Tsis tas li ntawd, cellulose ethers tuaj yeem txhim kho adhesion ntawm pob zeb thiab lwm yam ntaub ntawv, xws li hlau lossis ntoo.

Qhov zoo thiab qhov tsis zoo

Kev siv cellulose ethers hauv pob zeb muaj ntau yam zoo. Cellulose ethers tuaj yeem txhim kho kev ua haujlwm ntawm pob zeb, txo cov dej permeability thiab shrinkage, thiab txhim kho adhesion.
