Daim ntawv thov ntawm Sodium CarboxyMethyl Cellulose hauv Kev Lag Luam Ntawv

Kev siv Sodium CarboxyMethyl Cellulose hauv Kev Lag Luam Ntawv

Sodium carboxymethyl cellulose (CMC) yog ib qho khoom siv feem ntau siv hauv kev lag luam ntawv vim nws cov khoom tshwj xeeb, xws li siab viscosity, dej tuav, thiab muaj peev xwm ua yeeb yaj kiab. CMC tuaj yeem siv rau ntau theem ntawm cov txheej txheem papermaking los txhim kho qhov zoo thiab ua haujlwm ntawm cov khoom siv ntawv. Nov yog qee qhov kev siv ntawm CMC hauv kev lag luam ntawv:

Txheej: CMC tuaj yeem siv los ua tus neeg sawv cev txheej hauv papermaking los txhim kho qhov smoothness thiab glossiness ntawm daim ntawv. Nws tseem tuaj yeem txhim kho tus cwj mem nqus thiab luam ntawv zoo ntawm daim ntawv. CMC txheej tuaj yeem siv tau los ntawm kev txau, txhuam, lossis cov menyuam txheej.

Kev khi: CMC tuaj yeem siv los ua tus neeg sawv cev hauv cov khoom siv los txhim kho lawv lub zog thiab ua haujlwm ntev. Nws tuaj yeem pab khi cov fibers ua ke thiab tiv thaiv lawv los ntawm kev sib cais thaum lub sijhawm ua ntawv.

Sizing: CMC tuaj yeem siv los ua tus neeg sawv cev sizing hauv papermaking los txhim kho daim ntawv cov dej tsis kam thiab txo nws qhov porosity. CMC sizing tuaj yeem siv ua ntej lossis tom qab daim ntawv tsim, thiab nws tuaj yeem siv ua ke nrog lwm tus neeg sawv cev sizing.

Kev pab khaws cia: CMC tuaj yeem siv los ua kev tuav pov hwm hauv kev ua ntaub ntawv los txhim kho kev khaws cia ntawm cov fillers, fibers, thiab lwm yam khoom ntxiv. Nws tuaj yeem pab txo cov khoom pov tseg thiab txhim kho kev ua haujlwm ntawm cov txheej txheem papermaking.

Dispersant: CMC tuaj yeem siv los ua cov khoom tawg hauv cov txheej txheem papermaking kom tawg thiab tshem tawm cov khoom hauv dej. Nws tuaj yeem pab tiv thaiv agglomeration thiab txhim kho kev faib cov khoom ntxiv hauv daim ntawv pulp.

Zuag qhia tag nrho, kev siv CMC hauv kev lag luam ntawv tuaj yeem pab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov khoom siv ntawv, nrog rau kev ua kom zoo thiab kev ruaj khov ntawm cov txheej txheem papermaking.
