Carboxymethyl Cellulose (CMC)

Tshuaj ntxuav

1. Sodium carboxymethyl cellulose yog ib qho surfactant, uas siv tau ua ib qho anti-fouling re-deposition, uas yog cov dispersant thiab surfactant ntawm cov khoom me me, tsim ib txheej adsorption nruj nreem rau ntawm cov xim kom tiv thaiv nws rov adsorption ntawm cov fiber.

2. Thaum ntxiv sodium carboxymethyl cellulose rau hauv cov hmoov ntxhua khaub ncaws, cov tshuaj tuaj yeem sib npaug thiab yooj yim adsorbed rau ntawm qhov chaw ntawm cov khoom khov, tsim ib txheej ntawm hydrophilic adsorption nyob ib puag ncig cov khoom khov. Tom qab ntawd qhov nro ntawm qhov chaw ntawm cov kua thiab cov khoom khov tsawg dua qhov nro ntawm qhov chaw hauv cov khoom khov, thiab cov nyhuv ntub ntawm cov surfactant molecule rhuav tshem qhov sib koom ua ke ntawm cov khoom khov. Qhov no disperses cov av rau hauv dej.

3. Sodium carboxymethyl cellulose ntxiv rau hauv cov hmoov ntxhua khaub ncaws, uas muaj cov nyhuv emulsifying. Tom qab emulsifying roj nplai, nws tsis yooj yim rau sib sau ua ke thiab precipitate rau ntawm cov khaub ncaws.

4. Sodium carboxymethyl cellulose ntxiv rau hauv cov hmoov ntxhua khaub ncaws, uas muaj cov nyhuv ntub thiab tuaj yeem nkag mus rau hauv cov av hydrophobic, zom cov av ua cov khoom colloidal, yog li cov av yooj yim dua tawm hauv cov fiber.

Ntxiv zaub mov

CMC siv dav hauv kev lag luam khoom noj, hauv ntau yam dej haus mis nyuj, cov khoom qab zib, ua lub luag haujlwm ntawm kev ua kom tuab, ruaj khov thiab txhim kho qhov saj, hauv ice cream, qhob cij thiab pastes, instant noodles thiab instant pastes thiab lwm yam khoom noj, ua lub luag haujlwm ntawm kev tsim, txhim kho qhov saj, khaws dej, txhim kho kev tawv thiab lwm yam. Ntawm lawv, FH9, FVH9, FM9 thiab FL9 muaj kev ruaj khov zoo ntawm cov kua qaub. Cov khoom lag luam siab heev muaj cov yam ntxwv zoo ntawm kev ua kom tuab. CMC tuaj yeem daws tau qhov teeb meem ntawm kev sib cais cov khoom khov thiab cov kua dej ntawm cov dej haus lactic acid thaum cov protein ntau dua 1%, thiab tuaj yeem ua rau cov mis lactic acid muaj qhov saj zoo. Cov mis lactic uas tsim tau tuaj yeem tswj tau qhov ruaj khov hauv PH ntau ntawm 3.8-4.2, tuaj yeem tiv taus pasteurization thiab 135 ℃ instant sterilization txheej txheem, qhov zoo ntawm cov khoom ruaj khov thiab txhim khu kev qha, thiab tuaj yeem khaws cia ntawm qhov kub ib txwm rau ntau dua rau lub hlis. Cov khoom noj khoom haus qub thiab qhov saj ntawm yogurt tseem tsis hloov pauv. Cov dej khov nab kuab uas muaj CMC, tuaj yeem tiv thaiv kev loj hlob ntawm cov dej khov nab kuab, yog li cov dej khov nab kuab saj zoo heev thaum noj, tsis muaj nplaum, roj, rog thiab lwm yam saj tsis zoo. Ntxiv mus, qhov o tuaj yeem siab, thiab qhov kub thiab txias tsis kam thiab yaj kuj zoo. CMC rau cov noodles tam sim ntawd ua rau cov noodles tam sim ntawd muaj zog zoo, saj zoo, tiav cov duab, kua zaub tsis muaj turbidity, thiab tseem tuaj yeem txo cov roj (kwv yees li 20% qis dua li kev siv roj thawj).

Hom purity siab

Daim ntawv qib CMC yog siv rau daim ntawv sizing, yog li ntawd daim ntawv muaj qhov ceev ntau dua, zoo permeability number case, tuaj yeem txhim kho qhov kev sib txuas ntawm cov fibers hauv daim ntawv, yog li txhim kho daim ntawv thiab folding tsis kam. Txhim kho qhov kev sib txuas sab hauv ntawm daim ntawv, txo cov hmoov av luam ntawv thaum luam ntawv, lossis txawm tias tsis muaj hmoov av. Daim ntawv nto kom tau txais kev sib khi zoo thiab roj tsis kam los txhim kho qhov zoo ntawm kev luam ntawv. Qhov saum npoo ntawm daim ntawv txhim kho qhov ci ntsa iab, txo qhov porosity, thiab ua lub luag haujlwm ntawm kev khaws dej. Nws pab kom cov xim tawg, ntev lub neej ntawm lub scraper, thiab muab cov kua dej zoo dua, cov khoom siv kho qhov muag thiab kev hloov pauv luam ntawv rau cov qauv khoom siab.

Qib tshuaj txhuam hniav

CMC muaj pseudoplasticity zoo, thixotropy thiab aftergrowth. Cov tshuaj txhuam hniav ruaj khov, qhov sib xws yog qhov tsim nyog, qhov formability yog qhov zoo, cov tshuaj txhuam hniav tsis dej, tsis tev tawm, tsis ntxhib, cov tshuaj txhuam yog ci thiab du, mos, thiab tiv taus kev hloov pauv kub. Zoo sib xws nrog ntau yam khoom siv raw hauv cov tshuaj txhuam hniav; Nws tuaj yeem ua lub luag haujlwm zoo hauv kev ua kom zoo nkauj, sib txuas, noo noo thiab kho cov ntxhiab tsw.

Tshwj xeeb rau cov khoom siv ceramic

Hauv kev tsim cov khoom siv ceramic, lawv feem ntau siv rau hauv cov khoom siv ceramic embryo, glaze paste thiab floral glaze. CMC qib ceramic yog siv ua cov ntawv nplaum dawb hauv cov khoom siv ceramic billet los txhim kho lub zog thiab plasticity ntawm billet. Txhim kho cov txiaj ntsig. Hauv cov khoom siv ceramic glaze, nws tuaj yeem tiv thaiv cov dej nag ntawm cov khoom glaze, txhim kho lub peev xwm lo ntawm cov glaze, txhim kho kev sib txuas ntawm cov glaze dawb thiab txhim kho lub zog ntawm cov txheej glaze. Nws muaj permeability zoo thiab dispersion hauv cov glaze luam ntawv, yog li ntawd cov glaze luam ntawv ruaj khov thiab sib xws.

Cov roj av tshwj xeeb

Nws muaj cov yam ntxwv ntawm cov khoom sib hloov sib xws, siab purity thiab tsawg dosage, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov av nkos. Zoo tiv taus dej noo, tsis kam ntsev thiab alkaline, haum rau kev sib xyaw thiab siv cov dej ntsev thiab dej hiav txwv. Nws yog qhov tsim nyog rau kev npaj hmoov thiab lub sijhawm luv luv thickening hauv thaj chaw siv roj. Polyanionic cellulose (PAC-HV) yog cov viscosifier zoo heev nrog cov pulp ntau thiab muaj peev xwm txo cov dej poob hauv av nkos. Polyanionic cellulose (PAC-LV) yog cov kua dej zoo heev hauv cov av nkos, uas muaj kev tswj hwm zoo ntawm cov dej poob hauv dej hiav txwv thiab cov dej ntsev saturated. Haum rau cov av nkos uas nyuaj tswj cov khoom khov thiab ntau yam kev hloov pauv. CMC, ua cov kua dej gel fracturing, muaj cov yam ntxwv ntawm gelatinability zoo, muaj peev xwm nqa xuab zeb muaj zog, muaj peev xwm tawg roj hmab thiab cov khoom seem tsawg.
