Cov khoom siv tshuaj pleev ib ce thiab kho tus kheej
Sodium carboxymethyl cellulose yog siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej ua cov thickener, stabilizer, thiab emulsifier. Nws tuaj yeem pab txhim kho kev ntxhib los mos thiab sib xws ntawm cov khoom xws li tshuaj pleev, tshuaj zawv plaub hau, thiab tshuaj txhuam hniav.

Kev lag luam roj thiab roj
Sodium carboxymethyl cellulose yog siv nyob rau hauv kev lag luam roj thiab roj raws li ib tug drilling kua additive. Nws tuaj yeem pab ua kom cov viscosity ntawm cov kua dej drilling, tswj cov kua dej poob, thiab inhibit shale o thiab dispersion. Sodium carboxymethyl cellulose kuj tseem siv rau hauv hydraulic fracturing ua haujlwm ua cov thickener thiab viscosity enhancer.

Kev lag luam ntawv
Sodium carboxymethyl cellulose yog siv nyob rau hauv daim ntawv kev lag luam raws li ib tug txheej tus neeg sawv cev, binder, thiab ntxiv dag zog rau. Nws tuaj yeem pab txhim kho cov khoom saum npoo av thiab luam tawm ntawm cov khoom siv ntawv, nrog rau kev txhim kho lawv lub zog thiab kav ntev.
