Dab tsi yog qhov tseem ceeb ntawm kev siv carboxymethyl cellulose

Kev siv carboxymethyl cellulose yog cellulose ether nrog lub cev zoo tshaj plaws thiab tshuaj lom neeg thiab siv dav hauv kev lag luam cellulose ether, thiab kev siv carboxymethyl cellulose belongs rau non-ionic cellulose ethers.Vim tias HPMC muaj cov khoom zoo xws li thickening, emulsification, film forming, tiv thaiv colloid, noo noo retention, adhesion, enzyme kuj thiab metabolic inertness, carboxymethyl cellulose yog dav siv nyob rau hauv kev tsim kho, latex coatings, tshuaj, polychlorinated Ethylene, tshuaj niaj hnub, ceramics thiab ua liaj ua teb. ntau lawm.

Kev siv cov carboxymethyl cellulose Hauv kev tsim kho thiab cov khoom siv hauv tsev, lub luag haujlwm tseem ceeb ntawm HPMC yog ua kom cov viscosity, thicken, khaws dej, lubricate, txhim kho cov txheej txheem thiab cov twj tso kua mis ntawm cov cement thiab gypsum;Kev siv cov carboxymethyl cellulose nyob rau hauv latex Coatings yog tsuas yog siv los tiv thaiv colloids, thickeners thiab pigment suspending agents;kev siv cov carboxymethyl cellulose nyob rau hauv kev lag luam kws tshuaj yog tsuas yog siv rau kev npaj ntau lawm, raws li cov ntsiav tshuaj txheej thiab tsim binders, thiab yuav siv tau rau sustained tso tawm ntawm kev tsim tshuaj;Kev siv cov carboxymethyl cellulose yog siv rau hauv cov khoom siv tiv thaiv tus kheej hauv cov tshuaj niaj hnub, thiab kev siv carboxymethyl cellulose tuaj yeem txhim kho cov emulsification, anti-enzyme, dispersion, adhesion, deg kev ua si, film-forming, Moisturizing, foaming thiab lwm yam khoom;carboxymethyl cellulose kuj tseem siv rau hauv kev tsim cov polyvinyl chloride, feem ntau yog siv los ua ib qho dispersant nyob rau hauv cov tshuaj tiv thaiv polymerization ntawm ncua kev kawm ntawv polymerization system, thiab tam sim no muaj ntau yam ntau lawm nyob rau hauv lub ntiaj teb no lub ncua kev kawm ntawv polyvinyl chloride ntau lawm daim ntawv thov.Tsis tas li ntawd, kev siv cov carboxymethyl cellulose kuj yog siv los ua tus neeg sawv cev rau kev lag luam ceramic blanks thiab dispersant rau glaze;Hauv kev ua liaj ua teb, carboxymethyl cellulose yog siv los kho cov noob qoob loo, uas tuaj yeem ua kom cov qoob loo nce ntxiv, uas tuaj yeem tsis tsuas yog moisturize tab sis kuj tiv thaiv daim tawv nqaij.Yuav tiv thaiv mildew thiab lwm yam.

Taw qhia rau kev siv carboxymethyl cellulose:

Kev siv cov carboxymethyl cellulose yog ib qho uas tsis yog-ionic cellulose ether ua los ntawm tej yam ntuj tso polymer cov ntaub ntawv refined paj rwb los ntawm ib tug series ntawm tshuaj ua.Cov tsos ntawm carboxymethyl cellulose yog cov hmoov dawb, tsis muaj tshuaj lom, tsis qab thiab tsis muaj ntxhiab.Nws tuaj yeem yaj hauv dej txias kom tsim tau pob tshab viscous colloid.

1. Kev siv cov carboxymethyl cellulose muaj cov dej tuav tau zoo heev.Txawm hais tias lub mortar uas muaj carboxymethyl cellulose yog siv rau cov dej-nqus substrate, nws tuaj yeem tswj kev ua haujlwm ntawm cov mortar rau lub sijhawm ntev, thiab kev siv carboxymethyl cellulose yog sib xws nrog ntau cov surfactants thiab dej-raws li polymers.Kev siv cov carboxymethyl cellulose tuaj yeem ncua lub sijhawm qhib ntawm cov cement mortar, txhim kho kev ua haujlwm, txhim kho shrinkage thiab tawg tsis kam, thiab txhim kho qhov zoo.
2. Kev siv cov carboxymethyl cellulose Cov khoom yog qhov zoo, feem ntau ncav cuag 120 meshes, uas yooj yim dua rau kev sib xyaw nrog cov cement mortar, gypsum, txiv qaub thiab lwm yam ntaub ntawv, yog li cov khoom sib xyaw no tsis yooj yim rau agglomerate thaum dispersed hauv dej.
3. Carboxymethyl cellulose tuaj yeem siv rau hauv cov cement mortar, sab nrauv phab ntsa thermal rwb thaiv tsev thiab cov khoom zoo sib xws, tshwj xeeb tshaj yog rau sab nrauv phab ntsa thermal rwb thaiv tsev.
4. Kev siv carboxymethyl cellulose muaj lubricity zoo, thiab cov khoom siv tom qab siv hydroxypropyl methyl cellulose (HPMC) tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv, ua kom yooj yim rau kev siv cov trowel thiab txhim kho Anti-sliding muaj peev xwm ntawm mortar.
5. Kev siv cov carboxymethyl cellulose tuaj yeem txhim kho lub zog cohesive, pab cov mortar kom tsim tau cov neeg kho tshuab siab zog thaum lub sij hawm teeb tsa, thiab txhim kho lub zog cohesive thiab shear zog ntawm lub mortar.
