Cellulose binder-carboxymethyl cellulose (cmc)

Carboxymethyl cellulose (sodium carboxymethyl cellulose), yotchedwa CMC, ndi polymer pomwe wapamwamba kwambiri. Ndiwosanduka wopanda fungo, wopanda pake, wosakhazikika. Kulandila celluloser celluuse ndi mtundu wa ether ether, ndipo mchere wake wonse wa sodium uyenera kukhala, ndiye kuti dzina lake lonse liyenera kukhala sodium carboxyl cellouse, ndiye kuti, CMC-NA.

Monga methyl cellulose, carboxymethyl cellulose imatha kugwiritsidwa ntchito ngati chowonjezera cha zinthu zovomerezeka komanso ngati chomangira kwakanthawi chovomerezeka.

Sodium Carboxymethmethmethmethyl cellulose ndi mankhwala a polydeleclyrrolyte, kuti ithe kugwiritsa ntchito ngati obalalitsa ndi matope am'matontho okhazikika, ndipo imakhalanso yotentha kwambiri. Ali ndi izi:

1.

2. Popeza Carboxymethyl cellulose ndi polymer electrolyte, imatha kuchepetsa kulumikizana pakati pa tinthu tating'onoting'ono, ndikukhala ngati ma cololbor komanso oteteza, ndikuwongolera pambuyo pa kuperewera kwa bungwe;

Zojambulajambula:
1. CMC ndi yoyera kapena yachikasu ufa ufa, wopanda mphamvu, wopanda mphamvu, mosavuta m'madzi, ndipo njira yabwino kwambiri kapena yothetsera vuto. Itha kusungidwa kwa nthawi yayitali osawonongeka, ndipo zimakhazikika pansi pa kutentha kochepa ndi dzuwa. Komabe, chifukwa cha kusintha kwa kutentha kwamphamvu, acidity ndi matenda alkaria yankho adzasintha. Mothandizidwa ndi ma ray a ultraviolet ray ndi tizilombo tating'onoting'ono, zimayambitsa hydrolysis kapena makutidwe, mafayilo a yankho adzachepa, ndipo ngakhale yankho lidzawonongedwa. Ngati yankho liyenera kusungidwa kwa nthawi yayitali, osungirako otetezeka angasankhidwe, monga foroldehyde, phenol, benzoic acid, ndi orcury Corcounds.
2. CMC ndizofanana ndi ma electoll ena a polymer. Ikasungunula, choyamba zimatupa, ndipo tinthu tomwe timakonzerana wina ndi mnzake kupanga gulu la filimu kapena ma viscose, kuti asabalalike, koma chipulumutso sichichedwa. Chifukwa chake, pokonza yankho lake la madzi, ngati tinthu tating'onoting'ono titha kunyozedwe kaye, kuchuluka kwa chibadwa kumatha kuchuluka kwambiri.
3. CMC ndi hygroscopic. Chinyezi chambiri cha masentimita mumlengalenga chimawonjezeka ndikuwonjezeka kwa kutentha kwa mpweya ndipo kumachepa ndi kuchuluka kwa kutentha kwa mpweya. Kutentha kwa kutentha kwa chipinda ndi 80% -50%, chinyezi chofanana kwambiri kuposa 26%, komanso chinyezi chokwanira 10%. Chifukwa chake, kunyamula katundu komanso kusungiramo kumayenera kulabadira chinyezi.
4. Mchere wachitsulo wolemera monga zinc, mkuwa, chiwombankhanga, siliva, chitsulo, chromium, chromium hydroxide.
5. Organic kapena ovota ma asidi adzayambitsanso mpweya mu njirayi. Chiwonetsero cha mpweya mpweya ndiwosiyana chifukwa cha mtundu ndi kukhazikika kwa asidi. Nthawi zambiri, mpweya umachitika pansipa pH 2,5, ndipo itha kubwezeretsedwa pambuyo poti alkali.
6. Mchere monga calcium, magnesium ndi mchere wamchere ulibe mphamvu pa cmc yankho, koma amakhudza kuchepetsa mafayilo.
7..
8. Kanemayo adalumikizidwa ndi CMC atamizidwa mu acetone, Benzene, Busyl Tetthachloride, Mafuta, Tonoline, Turnyl, turlene, Mafuta Peanut, etc. sizingasinthe pasanathe maola 24.
