Cov khoom siv lub cev thiab tshuaj lom neeg thiab siv Cellulose Ethers

Cellulose ethers yog ib pawg ntawm cov dej-soluble polymers muab los ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag.Lawv tau siv dav hauv ntau qhov kev lag luam vim lawv lub cev thiab tshuaj lom neeg tshwj xeeb.Nov yog qee qhov kev siv lub cev thiab tshuaj lom neeg thiab kev siv cellulose ethers:

1. Lub cev muaj zog:

• Cellulose ethers yog dej-soluble thiab muaj peev xwm tsim pob tshab thiab viscous daws.
• Lawv muaj viscosity siab, uas ua rau lawv zoo li thickeners hauv ntau daim ntawv thov.
• Lawv ruaj khov ntawm ntau qib pH thiab tuaj yeem tiv taus qhov kub thiab txias.

2. Chemical Properties:

• Cellulose ethers yog muab los ntawm cellulose los ntawm kev hloov tshuaj, uas hloov cov khoom ntawm cov polymer.
• Qhov degree ntawm kev hloov pauv (DS) ntawm cellulose ethers yog hais txog tus naj npawb ntawm cov hloov pauv hauv ib chav tsev piam thaj hauv cov saw cellulose, uas cuam tshuam rau lawv cov solubility, viscosity, thiab lwm yam khoom.
• Hom kev hloov pauv, xws li methyl, ethyl, hydroxyethyl, hydroxypropyl, thiab carboxymethyl, txiav txim siab cov khoom tshwj xeeb ntawm cellulose ether.

3. Kev siv:

• Cellulose ethers yog dav siv los ua thickeners, stabilizers, binders, thiab zaj duab xis qub nyob rau hauv ntau yam lag luam, xws li tshuaj, khoom noj khoom haus, kev tu tus kheej, thiab kev tsim kho.
• Hauv kev lag luam kws tshuaj, cellulose ethers yog siv los ua cov khoom siv hauv cov ntsiav tshuaj thiab cov tshuaj ntsiav tshuaj, nrog rau cov tshuaj kho qhov muag, qhov ntswg, thiab tshuaj pleev.
• Hauv kev lag luam khoom noj khoom haus, cellulose ethers yog siv los ua cov khoom ua kom tuab hauv cov khoom noj siv mis, cov kua ntses, thiab dej haus, thiab ua kom ruaj khov hauv cov khoom ci thiab cov zaub xam lav.
• Hauv kev lag luam tu tus kheej, cellulose ethers yog siv rau hauv cov khoom tu plaub hau, xws li cov tshuaj zawv plaub hau thiab cov tshuaj kho mob, nrog rau cov khoom tu tawv nqaij, xws li tshuaj pleev thiab pleev.
• Hauv kev tsim kho kev lag luam, cellulose ethers yog siv los ua cov dej tuav dej thiab kev hloov kho rheology hauv cov khoom siv cement, xws li mortar thiab pob zeb.

Hauv cov ntsiab lus, cellulose ethers yog ib pawg ntau yam ntawm cov polymers uas muaj lub cev thiab tshuaj lom neeg tshwj xeeb.Lawv tau siv dav hauv ntau qhov kev lag luam vim lawv cov txiaj ntsig zoo li thickeners, stabilizers, binders, thiab zaj duab xis qub.
