Carboxymethyl cellulose (cmc)

Cov lus piav qhia luv luv:

Tam sim no, hloov kho cov thev naus laus zis ntawm cellulose feem ntau yog ethermau thiab eserification. Carboxymethylation yog ib hom ntawm etherilication thev naus laus zis. Carboxymethyl cellulose (cmc) yog tau los ntawm cellulose ntawm cellulose, zaj duab xis, zaub mov, cov ntaub ntawv, cov ntaub ntawv, cov ntaub ntawv thiab lwm yam lag luam. Nws yog ib qho ntawm cov kws ua haujlwm cellulose tshaj plaws.

Nws tau npaj los ntawm cellulose derivatives ntawm carboxymethyl hloov, uas tau kho nrog sodium hydroculose, thiab tom qab ntawd reacted nrog monochlocetic acid. Cov dej qab zib qab zib uas ua rau cov pab pawg cellulose muaj peb pawg neeg hloov tau, yog li cov khoom lag luam nrog cov hloov pauv sib hloov tuaj yeem tau txais. Thaum 1mmol Carboxymethyl tau qhia ib 1g qhov hnyav ntawm nruab nrab, nws yog insoluble hauv dej thiab dilute acid, tab sis tuaj yeem siv rau ion txauv cov chromatography. Carboxymethyl pka, kwv yees li 4 hauv 0.5Mol / L Carrothyl, nws tuaj yeem yaj nyob rau hauv cov dej khov kho nrog cov viscosity siab.

Khoom Siv Khoom Siv

Carboxymethyl cellulose (CMC) yog cov hmoov tsis muaj tshuaj dawb thiab tsis muaj qab hau dawb cov hmoov uas muaj zog nrog kev ua tau ruaj khov thiab tshem tawm cov dej khov. Nws cov kua aqueous yog nruab nrab lossis alkaline pob tshab viscesives, soluble adhesives thiab resins rau hauv cov kuab tshuaj ethanol. CMC tuaj yeem siv tau los ua phau binder, tuab, emiulsiftures, thiab lwm yam, feem ntau yog hu ua "Industrial MSG".

Kev xaub

1. Sodium CarbiSylethyl cellulose yog qhov semfactant txheej, uas tuaj yeem siv cov khoom tsis sib xws, uas yog qhov tsis sib xws los tiv thaiv nws cov adsorption rov ua kom muaj fiber.

2. Thaum sodium carboxymethyl cellulose tau ntxiv rau kev ntxhua khaub ncaws, tsim tau yooj yim cov txheej, sib sau ib txheej ntawm hydrophilic adsorption nyob ib ncig ntawm cov khoom seem. Tom qab ntawd cov nro ntawm cov kua thiab cov khoom khov yog tsawg dua li cov khoom siv nro hauv qab, thiab cov nyhuv ntub ntawm surfactant molecule rhuav tshem cov cohesion ntawm cov khoom seem. Qhov no disperses cov av rau hauv dej.

3. Sodium Carboxymethyl cellulose tau ntxiv rau khaub ncaws ntxhua khaub ncaws, uas muaj emulsifying nyhuv. Tom qab emulsifying roj teev, nws tsis yooj yim kom sib sau ua ke thiab nag lossis daus rau ntawm cov khaub ncaws.

4. Sodium Carboxymethyl cellulose tau ntxiv rau cov khaub ncaws ua khaub ncaws, uas muaj cov av ntub dej, kom cov av yooj yim kom tawm ntawm cov fiber.

Ntxiv rau

CMC tau dav siv hauv kev lag luam khoom noj khoom haus, ua rau muaj cov kua mis thiab cov khoom noj ua ke, ua kom zoo dua qub thiab cov khoom noj kom nrawm, ua kom zoo dua qub, tuav cov dej khov kho, txhim kho kom huv 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. CMC tuaj yeem ua tiav qhov teeb meem ntawm cov kua roj-kua sib cais thiab nag lossis daus ntau dua li 1%, thiab tuaj yeem ua cov mis nyuj protic acid muaj qhov saj zoo. Cov kua mis uas tau tsim tau tuaj yeem ua kom ruaj khov nyob rau hauv lub phua ntawm 3.8-4.2 lub tsev ua tsis muaj menyuam tsis muaj menyuam thiab ntseeg tau, thiab tuaj yeem khaws cia ntawm qhov kub thiab rau ntau tshaj rau lub hlis. Cov khoom noj khoom haus qub uas muaj pes tsawg leeg thiab cov tsw ntawm yogurt nyob twj ywm tsis hloov pauv. Mis nyuj khov nrog CMC, tuaj yeem tiv thaiv kev loj hlob ntawm cov muaju txias, yog li ntawd cov dej khov khov thaum noj mov, muaj roj nplaum, rog hnyav thiab lwm yam tsis zoo. Ntxiv mus, tus nqi o yog siab, thiab qhov kub tsis kam thiab melting tsis yog qhov zoo. CMC rau cov mij tsis muaj cov mij tsis muaj qhov zoo, ua kom tiav cov roj hmab (txog 20% qis dua li kev siv roj qub).

Siab hom

Daim ntawv qib CMC yog siv rau cov ntawv sizing, yog li cov ntawv muaj ntau dua kev ua kom zoo dua, yog li kev txhim kho cov ntawv thiab folding ua. Txhim kho cov nplaum sab hauv ntawm daim ntawv, txo cov ntaub ntawv luam tawm thaum lub tshuab luam ntawv, lossis txawm tias tsis muaj hmoov av. Daim ntawv saum npoo kom tau txais kev sib khi zoo thiab cov roj ua rau muaj cov luam ntawv txhim kho. Cov npoo ntawm cov ntawv txhim kho cov lus pubter, txo cov porosity, thiab ua lub luag haujlwm ntawm dej ceev. Nws pab txhawm rau tawg cov xim, ntxib lub neej ntawm cov scraper, thiab muab cov khoom zoo dua, kho qhov muag khoom thiab luam tawm kev yoog raws cov ntsiab lus zoo.

Qib Tshuaj Txhuam Hniav

CMC muaj cov paploplastic zoo, thixotrospy thiab tom qab. Cov tshuaj txhuam hniav ntawm cov tshuaj txhuam hniav yog ruaj khov, qhov kev sib xws yog qhov zoo, tsis muaj tshuaj txhuam, tsis muaj qhov zoo, tsis txhob tawm mus rau qhov ntsuas kub. Kev sib xyaw zoo nrog ntau cov ntaub ntawv tso tawm hauv cov tshuaj txhuam hniav; Nws tuaj yeem ua lub luag haujlwm zoo nyob rau hauv shaping, tsev neeg, moisturizing thiab kho cov tshuaj tsw qab.

Tshwj xeeb rau Ceramics

Hauv kev tsim khoom Ceramic, lawv tau siv nyob rau hauv ceramic emryryo, ci muab muab tshuaj txhuam thiab nplaim taws. Ceramic los CMC yog siv raws li phau ntawv tsis zoo nyob rau hauv Creamic Billet txhawm rau txhim kho lub zog thiab cov yas ntawm cov billet. Txhim kho cov txiaj ntsig. Hauv cov kab ceramic ci, nws tuaj yeem tiv thaiv cov dej nag, txhim kho cov nplaum muaj peev xwm ntawm lub ntsej muag dawb paug, txhim kho lub zog ntawm cov ci ntsa iab. Nws muaj zoo permeability thiab dispersion hauv lub tshuab luam ntawv ci, yog li ntawd luam ntawv ci ci yog ruaj khov thiab hnav khaub ncaws.

TSHWJ XEEB Oilfield

Nws muaj cov yam ntxwv ntawm kev hloov pauv molecules, siab purity thiab tsawg tsawg tshuaj, uas tuaj yeem txhim kho cov txheej txheem av nkos. Zoo noo noo tsis kam, ntsev tiv taus thiab alkaline kuj, haum rau kev sib xyaw thiab siv cov ntsev lim dej thiab dej hiav txwv. Nws yog haum rau hmoov npaj thiab luv luv thickening lub sijhawm nyob rau hauv cov roj siv. Polyanionic cellulose (PAC-HV) yog cov viscosifier zoo nrog lub peev xwm siab los txo cov dej poob hauv av nkos. Polyanionic cellulose (PAC-LV) yog cov dej ntws zoo heev hauv av nkos, uas muaj cov dej tsis txaus nyob hauv cov av nkos dej av nkos. Haum rau cov av nkos nrog kev nyuaj los tswj cov ntsiab lus thiab ntau yam ntawm kev hloov pauv. CMC, raws li ib tug gel fracturing kua, muaj cov yam ntxwv ntawm zoo gelatinability, muaj zog sand nqa muaj peev xwm, roj hmab rreaking muaj peev xwm thiab cov khoom seem.
