I-selsulose binder-carboxeyymethyl seluplose (cmc)

I-carboxeymethyl seluplose (i-sodium carboxethyl seluplose), ekubhekiswa kuyo njenge-CMC, yi-polymer ye-polymer ye-colloid esebenzayo. Yinto engenakuthelekiswa nanto, engenaxabiso, engafakwanga amanzi angenabungozi. I-binder efunyenweyo ye-selsulose ye-binder luhlobo lwe-selsulose i-ether, kwaye ityuwa yayo yesodium isetyenziswa, ke igama layo elipheleleyo lifanele libe yi-sodium yebhokisi ye-sodium, oko kukuthi, cmc-na.

Njenge-methyl seluplose, i-carboxeyymethyl seluplose inokusetyenziswa njenge-surticant yezinto ezisetyenziswayo kunye nokubhalwa okwethutyana kwimithombo yomvuzo.

I-Sodium Carboxymethyl Selelose ye-Polyectrolyte, ukuze isetyenziswe njengomsasazi kunye nokuzinzisa kodaka oluhlaziyiweyo kunye neziphoso zethutyana. Inezibonelelo zilandelayo:

I-1. I-carboxymethyl seluplose inokubekwa kakuhle kumphezulu wamasuntswana, ingeniswe kakuhle kwaye iqhagamshelwe kumasuntswana, ukuze kupapashwe ngamandla amakhulu;

2. Kuba i-carboxymethyl seluplose yi-anionrolyte ye-anion, inokunciphisa ukusebenzisana phakathi kwamasuntswana, kwaye isebenze njengendawo yokusebenza kunye nokuncitshiswa kwemveliso ye-inshomnity yesakhiwo sombutho;

3. Sebenzisa i-carboxymethyl seluplose njenge-binder, akukho ash emva kokutsha, kwaye zimbalwa kakhulu izixhobo ezilula, ezingayi kuchaphazela ubushushu benkonzo yemveliso.

Iimpawu zemveliso:
I-1. I-CMC i-White okanye i-tyuty ityheli yomgubo, engenakuthelekiswa nanto, engenatyhefu, engenatyhefu emanzini, kwaye isisombululo esibonakalayo okanye i-alkaline engathathi hlangothi. Ingagcinwa ixesha elide ngaphandle kokuthathwa, kwaye iyazinza phantsi kobushushu obuphantsi kunye nokukhanya kwelanga. Nangona kunjalo, ngenxa yotshintsho olukhawulezileyo lobushushu, i-acidity kunye ne-alkalinity yesisombululo siza kutshintsha. Phantsi kwempembelelo ye-rays ye-ultraviolet kunye ne-microorganisms, iya kubangela i-hydrolysis okanye i-oxidation, i-vidasity yesisombululo iya kuncipha. Ukuba isisombululo kufuneka sigcinwe ixesha elide, izinto ezifanelekileyo ezichanekileyo zinokukhethwa, njenge-formaldehyde, phenol, i-benzoic acid, kunye nemichiza ye-orgaric.
2. I-CMC iyafana nezinye i-polymer ye-polymer. Xa inyibilikisa, iya kuqala ukungqumbela, kwaye amasuntso aya kulandelana omnye komnye enze iqela lefilimu okanye iqela le-viscose, kodwa ukuchithwa kucotha. Ke ngoko, xa ulungiselela isisombululo sayo esiyi-AICT, ukuba amasuntswana anokufakwa kumanzi ngokufanayo, ireyithi yokuchithwa inokunyuswa kakhulu.
I-3. I-CMC i-hygroscopic. Umkhuhlane ophakathi we-CMC kwimozulu unyuka ngokunyuka kobushushu bomoya kwaye kuncipha ngokunyuka kobushushu bomoya. Xa iqondo lobushushu eliphakathi lobushushu begumbi lingama-80% -50%, umswakama wokulingana ungaphezulu kwe-26%, kunye nomswakama wemveliso ngaphantsi kwe-10%. Ke ngoko, ukupakishwa kwemveliso kunye nokugcinwa kufuneka kunikele ingqalelo ekufumeni komswakama-ubungqina.
4. Iityuwa zentsimbi ezinzima ezinjenge-zinc, ubhedu, kukhokelo, ialuminiya, i-chromium, i-chromium, i-chromium, njl.
I-5. I-Organic okanye i-Inorganic Acids iya kubangela i-pucipity kwisisombululo sale mveliso. I-phenomenon yomhlaba yahlukile ngenxa yohlobo kunye nokugxininiswa kwe-acid. Ngokubanzi, ukulunga kwenzeka ngezantsi kwe-2,5, kwaye inokufunyanwa kwakhona emva kokungathathi cala ngokudibanisa i-alkali.
I-6. Iityiwa ezinje nge-calcium, i-magnesium kunye netyuwa yetafile ayinayo ifuthe loqobo kwisisombululo se-CMC, kodwa ichaphazele ukuncitshiswa kwe-viscofity.
I-7. I-CMC iyahambelana nezinye iibhanti ezinyibilikayo zamanzi, ukuzithoba kunye ne-resins.
8. Ifilimu etsalwa yi-CMC intywiliselwa kwi-acetone, i-Benzene, i-ricbon ye-tetroum, i-ethanol, i-methyne, i-tuanchene, i-tuanut, ye-tuanut, yeoyile, njl. ayinakutshintsha ngaphakathi kweeyure ezingama-24.
