I-Cellulose Binder-Carboxymethyl Cellulose (CMC)

I-Carboxymethyl Cellulose (i-sodium carboxymethyl celtuleose), okukhulunywa ngayo njenge-CMC, iyingxenye ye-polymer ye-colloid esebenzayo engaphezulu. Kuyinto engenamsindo, engenabutha, engenamthana yamanzi ancibilikayo. I-Organic Cellulose Binder uhlobo lwe-cellulose ether, futhi usawoti wawo we-sodium ngokuvamile asetshenziswa, ngakho-ke igama layo eligcwele kufanele libe yi-sodium carboxymethyl cellulose, okungukuthi, cmc-na.

Njenge-methylllose, i-carboxymethyl celtule

I-Sodium Carboxymethyl celtulose iyi-polyelectslyte yokwenziwa, ngakho-ke ingasetshenziswa njenge-distrindant and stabilizer yodaka lokuya kanye nezinkanjiswa, futhi kungukusebenza okuphezulu kwesikhashana kwe-organic. Inezinzuzo ezilandelayo:

1. I-Carboxymethyl celtulese ingahle i-adsorbese kahle ebusweni bezinhlayiya, ezingena kahle futhi ezixhunyiwe kwizinhlayiya, ukuze izikhala ezingezinhlelo ezinamandla ezibucayi zingakhiqizwa;

2. Njengoba i-carboxymethyl celtulose iyi-anionic polymer eledylyte, kunganciphisa ukuxhumana phakathi kwezinhlayiya ngemuva kokuhlungwa ebusweni bezinhlayiyana, bese wenza ngcono ubuningi bomkhiqizo nokwenza ngcono i-inhomogeneity yesakhiwo senhlangano;

3. Kusetshenziswa i-carboxymethyl celtulose njenge-binder, akukho umlotha ngemuva kokuvutha, futhi kunezinto ezimbalwa ezincibilikayo eziphansi eziphansi, ezingeke zithinte izinga lokushisa lenkonzo lomkhiqizo.

Izici zomkhiqizo:
1. I-CMC i-powder emhlophe noma ephuzi, ayinambitha, ayinambitha, ingenamzimba, ayinobuthi, incibilika kalula emanzini, futhi yakha i-colloid esobala, futhi ikhambi alikho ngaphansi komhlaba noma kancane. Ingagcinwa isikhathi eside ngaphandle kokuwohloka, futhi kuzinze futhi ngaphansi kokushisa okuphansi nokukhanya kwelanga. Kodwa-ke, ngenxa yokushintshwa okusheshayo kwamazinga okushisa, i-acidity kanye ne-alkalinity yekhambi lizoshintsha. Ngaphansi kwethonya lemisebe ye-ultraviolet kanye nama-microorganisms, kuzokwenza futhi ukuthi i-hydrolysis noma i-oxidation, i-viscosity yekhambi izokwehla, futhi nekhambi lizonakaliswa. Uma isixazululo kufanele sigcinwe isikhathi eside, izivikelo ezifanele zingakhethwa, njenge-formaldehyde, i-phenol, i-benzoic acid, kanye nezinhlanganisela ze-mercury eziphilayo.
2. I-CMC iyafana namanye ama-electrolyte e-polymer. Lapho ihlakazeka, izoqala ukuvuvukala, futhi izinhlayiya zizonamathela komunye nomunye ukwakha iqembu lefilimu noma le-viscose, ukuze lingakwazi ukuhlakazeka, kepha ukuchithwa kuhamba kancane. Ngakho-ke, lapho ulungiselela ikhambi lalo elinamanzi, uma izinhlayiya zingamangele ngokufana, izinga lokuchithwa lingakhuphuke kakhulu.
3. I-CMC i-hygroscopic. Umswakama ojwayelekile we-CMC emkhathini ukhuphuka ngokunyuka kokushisa komoya futhi wehla ngokwanda kokushisa komoya. Lapho izinga lokushisa elijwayelekile lokushisa kwegumbi lingama-80% -50%, umswakama wokulingana ungaphezulu kwe-26%, kanye nomswakama womkhiqizo ongaphansi kwe-10%. Ngakho-ke, ukupakishwa komkhiqizo nokulondolozwa kufanele kunake ubufakazi boMswakama.
4. Usawoti wensimbi osindayo njenge-zinc, yethusi, ukuhola, i-aluminium, isiliva, i-iron, i-tip, kungaphazamisa ukuncibilika ku-sodium hydroxide noma i-ammonium hydroxide solution ngaphandle kwe-acetate eyisisekelo yokuhola.
5 Umcimbi wezulu uhlukile ngenxa yohlobo nokuhlushwa kwe-acid. Ngokuvamile, ukuhanjiswa kwezulu kwenzeka ngaphansi kwe-PH 2.5, futhi kungatholwa ngemuva kokungathathi hlangothi ngokungeza i-Alkali.
6. Usawoti onjenge-calcium, i-magnesium kanye nosawoti wethebula awunawo umphumela wemvula kwikhambi le-CMC, kepha kuthinte ukuncishiswa kokubonakala.
7. I-CMC iyahambisana nezinye izinto ezinyibilika amanzi, amathafa kanye nama-resins.
8. Ifilimu elidonswe yi-CMC ligxila e-Acethene, eBenzene, e-Tetrachloride, i-castor tetrachloride, i-ethanol, i-ethet, i-ethety, i-ethetteate, uwoyela wamathambo, njll. Kungenzeka kungashintshi kungakapheli amahora angama-24.
