Dab tsi yog qhov txawv ntawm Carbackymethyl cellulose (CMC) thiab polyanionic cellulose (PAC)?

Carboxymethyl cellulose (cmc)thiabPolyanionic cellulose (PAC)Yog ob lub cellulose cellulose derivatives, uas tau siv dav hauv ntau thaj teb, tshwj xeeb tshaj yog hauv Maas, roj av, khoom noj khoom haus thiab cov tshuaj noj thiab cov tshuaj thiab cov tshuaj. Lawv qhov sib txawv tseem ceeb tau cuam tshuam hauv cov qauv molecular, muaj nuj nqi, kev thov daim ntawv thov thiab ua haujlwm.

1. Qhov sib txawv hauv cov qauv molecular

Carboxymethyl cellulose (CMC) yog ib qho kev qhia ntawm Carboxymethyl (-ch2Cooh) pab pawg molecules los ntawm kev siv tshuaj lom neeg. Nws cov qauv tuaj yeem qhia ib lossis ntau cov pab pawg carboxymethyl ntawm qee yam hydroxyl txoj haujlwm ntawm cellulose los ntawm carboxymethylation cov tshuaj tiv thaiv. CMC feem ntau pom tias yog cov hmoov dawb lossis me ntsis daj, uas tuaj yeem tsim cov pob tshab los yog me ntsis turbid colutes tom qab tau yaj hauv dej.

Polyanionic cellulose (PAC) yog tau los ntawm cov tshuaj tiv thaiv tshuaj lom neeg xws li phosphorylation thiab etherification ntawm cellulose ntawm cellulose. Tsis zoo li Kimacell®cm, xws li cov pab pawg phosphate hauv Kimacular ntawm cov pab pawg neeg aqueous thiab nag lossis daus nrog lwm cov tshuaj cationic. PAC feem ntau yog lub paj dawb lossis lub teeb daj ua kom zoo nrog cov dej solubility zoo thiab viscosity ntau dua li cmc thaum yaj.

2. Qhov sib txawv hauv cov haujlwm thiab ua yeeb yam

Kev ua tau zoo ntawm CMC:

Thickening thiab gelling cov khoom: CMC tuaj yeem nce cov tshuaj tua kab hauv aqueous thiab yog cov neeg sawv cev zoo nkauj thiab txiv neej zoo heev. Nws cov nyhuv thickening feem ntau yog los ntawm cov hydration ntawm cov roj av thiab tus nqi them ntawm cov carboxylmethyl pawg ntawm nws.

Emulsification thiab stabilization: CMC muaj cov txiaj ntsig zoo emulsification thiab tuaj yeem siv los ua emulsifier hauv cov zaub mov thiab cov tshuaj pleev ib ce.

Adhesion: CMC muaj qee cov khoom nplaum, uas tuaj yeem txhim kho cov nplaum thiab yog siv dav hauv cov roj av, tsim kho thiab lwm yam lag luam.

Dej solubility: CMC tuaj yeem yaj hauv dej los ua cov tshuaj khov kho thiab yog siv dav hlau, ntawv, textiles thiab cov zaub mov.

Kev ua tau ntawm PAC:

Polymer tsub nqi zog: PAC muaj qhov kev ua kom muaj zog them ntau dua, uas ua rau rov qab nrog cov tshuaj polymers thiab hlau ions nyob rau hauv aqueous cov tshuaj, uas qhia txog kev kho dej ua dej muaj zog.

Viscosity Haum: piv nrog CMC, cov kua aqueous ntawm PAC muaj cov kev tswj hwm roj ntau dua thiab kav dej kom zoo rau cov kua dej.

Hydrolysis Stability: PAC muaj zoo Hydrolysis ruaj ntseg ntawm cov txiaj ntsig sib txawv, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig, thiab muaj peev xwm tswj tau muaj zog ua haujlwm, yog li nws tau siv dav hauv cov acidic roj ntau lawm.

Flocculation: PAC feem ntau siv nyob rau hauv kev kho dej dej thiab tuaj yeem zoo flocculate tshem tawm cov nplais hauv dej, uas pab ua kom huv lub cev dej.

3. Cov chaw thov tseem ceeb

Daim ntawv thov CMC:

Kev Lag Luam Khoom Noj: CMC tau siv dav hauv jelly, mis nyuj khov, condiments, condiments, condiments thiab lwm yam khoom ua cov tuab thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier thiab emulsifier. Nws tuaj yeem txhim kho qhov ruaj khov thiab saj ntawm cov khoom.

Kws Tsim Kho Kev Lag Luam: CMC yog siv hauv kev npaj ua lag luam ua ib zaj yeeb yaj kiab yeeb yaj kiab thiab tus neeg sawv cev tso tawm los pab cov tshuaj tawm qeeb hauv lub cev. Ib qho ntxiv, nws kuj yog siv hauv cov khoom lag luam xws li kua yeeb thiab kua.

Kev lag luam thiab textile kev lag luam: hauv cov ntawv Production, Kimacell®cc ua raws li cov tuab thiab moisturizer txhawm rau txhim kho lub ntsej muag du thiab lub zog; Hauv kev lag luam textile, cmc yog siv nyob rau hauv zas dispersion thiab zas xim.

Kev Daus Roj: CMC ua raws li cov tuab tuab hauv cov kua dej ua kom nce cov av nkos thiab txhim kho rheology thaum lub sijhawm khiav haujlwm.

Daim ntawv thov PAC:

Cov roj Extraction: Kimacell® ntawm Rheology Purseurator thiab roj nplua nyeem thiab roj tawm hauv cov roj ntsha thiab roj kev sib txhuam ntawm cov tshuaj txhuam thiab ua kom nruj thiab viscosity.

Kev kho dej: PAC feem ntau siv nyob rau hauv kev kho dej kom huv thiab haus dej, thiab tuaj yeem tshem tawm cov teeb meem tsis zoo, cov kab mob hnyav thiab cov kab mob hauv dej. Nws yog dav siv nyob hauv nroog dej phwj tuaj kho.

Kev lag luam tsim kev tsim kho: PAC ua raws li cov cement admixture kom haum cov fluidity thiab viscosity ntawm cement slurry thiab txhim kho kev ua haujlwm zoo.

Textile kev lag luam: PAC tuaj yeem siv tau ua tus ntsuas tus ntsuas kom txhim kho qhov kev tawm tsam thiab xim nrawm nrawm ntawm kev tuag.

4. Cov khoom sib piv

CmcthiabPacyog ob lub cellulose derivatives nrog cov tshuaj sib txawv thiab cov haujlwm. CMC feem ntau yog tus yeeb yam los ntawm nws cov thickening, emulsify thiab stetilizing tej yam thiab yog siv hauv cov zaub mov, tshuaj, ntawv thiab textile Industries; Thaum PAC yog dav siv nyob rau hauv cov liaj teb cov roj tawm thiab kev kho dej vim nws cov dej siab ntev, cov dej solubility zoo thiab cov dej ua haujlwm zoo thiab dej kho. Ob qho tib si muaj lawv tus kheej cov txiaj ntsig hauv kev ua tiav thiab daim ntawv thov, thiab cov khoom siv uas siv feem ntau yog nyob ntawm cov kev thov tshwj xeeb thiab ib puag ncig.
