Nws yog npaj los ntawm cellulose derivatives ntawm carboxymethyl substituents, uas yog kho nrog sodium hydroxide los tsim alkali cellulose, thiab ces reacted nrog monochloroacetic acid.Cov piam thaj uas ua rau cellulose muaj peb pawg hydroxyl hloov tau, yog li cov khoom uas muaj ntau qib hloov pauv tau.Thaum 1mmol carboxymethyl yog qhia rau 1g qhuav qhov hnyav ntawm qhov nruab nrab, nws yog insoluble hauv dej thiab dilute acid, tab sis tuaj yeem o thiab siv rau ion pauv chromatography.Carboxymethyl pKa, kwv yees li 4 nyob rau hauv dej ntshiab thiab 3.5 hauv 0.5mol/L NaCl, yog ib tug tsis muaj zog acidic cation exchanger, feem ntau yog siv rau kev sib cais ntawm nruab nrab thiab theem pib proteins ntawm pH > 4. Thaum ntau tshaj 40% hydroxyl pawg yog carboxymethyl, nws tuaj yeem yaj hauv dej los tsim cov tshuaj colloidal ruaj khov nrog viscosity siab.

Khoom siv
Carboxymethyl cellulose (CMC) yog non-toxic thiab tasteless dawb flocculent hmoov nrog kev ua haujlwm ruaj khov thiab yooj yim rau yaj hauv dej.Nws cov tshuaj aqueous yog nruab nrab lossis alkaline pob tshab kua nplaum, soluble hauv lwm cov dej-soluble adhesives thiab resins, thiab insoluble hauv organic solvents xws li ethanol.CMC tuaj yeem siv los ua binder, thickener, suspension agent, emulsifier, dispersant, stabilizer, sizing agent, thiab lwm yam Carboxymethyl cellulose (CMC) yog cov khoom loj tshaj plaws ntawm cellulose ether, feem ntau siv, cov khoom siv yooj yim tshaj plaws, feem ntau hu ua " industrial MSG".
Detergency
1. Sodium carboxymethyl cellulose yog ib qho surfactant, uas tuaj yeem siv los ua cov tshuaj tiv thaiv fouling re-deposition, uas yog cov dispersant thiab surfactant ntawm cov stain hais, tsim cov txheej adsorption nruj ntawm cov stain kom tiv thaiv nws rov qab adsorption ntawm fiber ntau. .
2. Thaum sodium carboxymethyl cellulose ntxiv rau cov hmoov ntxhua, cov tshuaj tuaj yeem sib npaug sib npaug thiab yooj yim adsorbed rau ntawm qhov chaw ntawm cov khoom, tsim ib txheej ntawm hydrophilic adsorption nyob ib ncig ntawm cov khoom siv.Tom qab ntawd qhov nro ntawm cov kua thiab cov khoom siv yog tsawg dua li qhov nro ntawm cov khoom hauv cov khoom, thiab cov nyhuv ntub dej ntawm cov tshuaj surfactant molecule rhuav tshem cov cohesion ntawm cov khoom.Qhov no disperses cov av rau hauv av.
3. Sodium carboxymethyl cellulose yog ntxiv rau cov hmoov ntxhua khaub ncaws, uas muaj cov nyhuv emulsifying.Tom qab emulsifying roj nplai, nws tsis yog yooj yim los sib sau ua ke thiab precipitate ntawm khaub ncaws.
4. Sodium carboxymethyl cellulose yog ntxiv rau cov hmoov ntxhua khaub ncaws, uas muaj cov nyhuv ntub dej thiab tuaj yeem nkag mus rau hauv cov av hydrophobic, crushing cov av particles rau hauv colloidal hais, kom cov av yog yooj yim dua tawm ntawm fiber ntau.
Khoom noj khoom haus ntxiv
CMC yog dav siv nyob rau hauv kev lag luam khoom noj khoom haus, nyob rau hauv ntau yam mis nyuj haus, condiments, plays lub luag hauj lwm ntawm thickening, stabilizing thiab txhim kho saj, nyob rau hauv ice cream, qhob cij thiab pastes, instant noodles thiab instant pastes thiab lwm yam khoom noj, ua lub luag hauj lwm. ntawm kev tsim, txhim kho saj, khaws cia dej, txhim kho toughness thiab lwm yam.Ntawm lawv, FH9, FVH9, FM9 thiab FL9 muaj cov kua qaub zoo.Cov khoom lag luam siab ntxiv muaj cov khoom zoo thickening.CMC tuaj yeem ua tiav qhov teeb meem ntawm cov kua dej sib cais thiab nag lossis daus ntawm cov dej haus lactic acid thaum cov ntsiab lus protein ntau dua 1%, thiab tuaj yeem ua rau cov kua mis lactic acid muaj qhov saj zoo.Cov kua mis lactic muaj peev xwm tswj tau kev ruaj ntseg hauv PH ntau ntawm 3.8-4.2, tuaj yeem tiv taus pasteurization thiab 135 ℃ instantaneous sterilization txheej txheem, cov khoom zoo yog ruaj khov thiab txhim khu kev qha, thiab tuaj yeem khaws cia ntawm qhov kub thiab txias rau ntau tshaj rau lub hlis.Tus thawj khoom noj muaj pes tsawg leeg thiab tsw ntawm yogurt nyob twj ywm unchanged.Cov dej khov nab kuab nrog CMC, tuaj yeem tiv thaiv kev loj hlob ntawm cov dej khov nab kuab, kom cov dej khov khov saj tshwj xeeb tshaj yog du thaum noj, tsis muaj nplaum, greasy, rog hnyav thiab lwm yam tsis zoo saj.Ntxiv mus, qhov o tus nqi yog siab, thiab qhov kub thiab txias tsis kam thiab melting kuj zoo.CMC rau cov noodles tam sim no ua rau cov noodles muaj lub zog zoo, saj zoo, ua tiav cov duab, tsis muaj turbidity ntawm cov kua zaub, thiab tseem tuaj yeem txo cov roj cov ntsiab lus (li 20% qis dua qhov qub roj noj).
Hom purity siab
Daim ntawv qib CMC yog siv rau daim ntawv sizing, kom daim ntawv muaj ntau qhov ntom ntom, zoo number case permeability, tuaj yeem txhim kho qhov adhesion ntawm fibers hauv daim ntawv, yog li txhim kho daim ntawv thiab folding kuj.Txhim kho cov adhesion sab hauv ntawm daim ntawv, txo cov plua plav tawm thaum luam ntawv, lossis txawm tias tsis muaj plua plav.Daim ntawv saum npoo kom tau txais kev sib khi zoo thiab roj ua haujlwm los txhim kho kev luam ntawv zoo.Qhov saum npoo ntawm daim ntawv txhim kho cov luster, txo cov porosity, thiab plays lub luag haujlwm ntawm dej tuav.Nws pab kom tawg cov xim, ncua lub neej ntawm scraper, thiab muab kev zoo dua fluidity, optical zog thiab luam ntawv adaptability rau siab cov ntsiab lus formulations.
Tshuaj txhuam hniav qib
CMC muaj pseudoplasticity zoo, thixotropy thiab aftergrowth.Cov tshuaj txhuam hniav yog qhov ruaj khov, qhov sib xws yog qhov tsim nyog, qhov tsim tau zoo, cov tshuaj txhuam hniav tsis muaj dej, tsis tev, tsis coarse, cov tshuaj txhuam yog ci thiab du, muag heev, thiab tiv taus qhov kub thiab txias.Kev sib raug zoo nrog ntau yam ntaub ntawv raw hauv cov tshuaj txhuam hniav;Nws tuaj yeem ua lub luag haujlwm zoo hauv shaping, bonding, moisturizing thiab kho cov tshuaj tsw qab.
Tshwj xeeb rau ceramics
Hauv kev tsim cov khoom siv ceramic, lawv feem ntau siv hauv ceramic embryo, glaze paste thiab paj glaze.Ceramic qib CMC yog siv los ua cov ntaub ntawv dawb huv hauv cov pob zeb ceramic los txhim kho lub zog thiab cov yas ntawm cov pob zeb.Txhim kho cov qoob loo.Nyob rau hauv ceramic glaze, nws tuaj yeem tiv thaiv nag lossis daus ntawm glaze hais, txhim kho lub peev xwm adhesion ntawm glaze, txhim kho kev sib raug zoo ntawm cov glaze dawb paug thiab txhim kho lub zog ntawm txheej glaze.Nws muaj zoo permeability thiab dispersion nyob rau hauv lub printing glaze, thiaj li hais tias cov printing glaze yog ruaj khov thiab uniform.
Tshwj xeeb oilfield
Nws muaj cov yam ntxwv ntawm kev hloov pauv cov molecules, siab purity thiab tsawg npaum li cas, uas tuaj yeem txhim kho cov txheej txheem av nkos.Zoo noo noo tsis kam, ntsev tsis kam thiab alkaline tsis kam, haum rau kev sib xyaw thiab siv cov dej ntsev ntsev thiab dej hiav txwv.Nws yog tsim rau hmoov npaj thiab lub sij hawm luv luv thickening nyob rau hauv cov roj exploitation teb.Polyanionic cellulose (PAC-HV) yog ib qho zoo viscosifier nrog lub siab pulp tawm los thiab muaj peev xwm txo tau dej hauv av nkos.Polyanionic cellulose (PAC-LV) yog cov kua dej tsis zoo hauv cov av nkos, uas muaj kev tswj xyuas zoo tshwj xeeb ntawm cov dej poob hauv dej hiav txwv av thiab cov dej ntsev saturated av nkos.Haum rau cov av nkos uas tsis yooj yim rau kev tswj cov ntsiab lus thiab ntau yam kev hloov pauv.CMC, raws li ib tug gel fracturing kua, muaj cov yam ntxwv ntawm zoo gelatinability, muaj zog xuab zeb nqa peev xwm, roj hmab tawg muaj peev xwm thiab tsawg residue.
