Carboxymethyl cellulose CMC-shahaadada baytari

Sharaxaad Gaaban:

Falcelinta Carboxymethylation waa mid ka mid ah tignoolajiyada etherification.Ka dib markii Carboxymethylation of cellulose, carboxymethyl cellulose (CMC) waa la helay.Xalka aqueous wuxuu leeyahay hawlaha dhumucdiisuna, film-samaynta, bonding, haynta biyaha, ilaalinta colloidal, emulsification iyo hakinta.Waxa si weyn looga isticmaalaa batroolka, cuntada, dawooyinka, warshadaha dharka iyo waraaqaha.Waa mid ka mid ah ethers-ka cellulose-ka ugu muhiimsan. Iyadoo khibradeena dheer ee ganacsiga alaabta kiimikada, ma waxaan ku siinaynaa talo xirfadeed oo ku saabsan alaabta iyo xalalka loo habeeyey ujeedadaada gaarka ah.Waxaan ku faraxsanahay inaan kaa caawino inaad doorato alaabta kugu habboon. Kaliya dhagsii si aad u hesho codsiyada warshadahaaga: CMC ee cuntada, batroolka, daabacaadda iyo dheehidda, ceramics, daawada cadayga, faa'iidada sabayn, batteriga, dahaarka, budada putty iyo samaynta waraaqaha.

Qaabka batteriga heerka CMC:BYT8 BYT9 BYT80
Alaabooyinka CMC, oo ah xabagta ugu weyn ee nidaamka aqueous qalabka korantada taban, waxaa si weyn u isticmaala soosaarayaasha batteriga gudaha iyo dibaddaba.Qadarka ugu fiican ee xabaggu wuxuu heli karaa awoodda batteriga oo aad u weyn, nolol wareeg ah iyo iska caabin hoose oo gudaha ah.Sidaa darteed, marka loo eego habka wax soo saarka ee warshadaha batteriga iyo shuruudaha waxqabadka gaarka ah ee alaabooyinka, si wax ku ool ah u wanaajiya habka wax soo saarka ee alaabta CMC iyo bilawga alaabta batteriga gaarka ah.

CMC-Codsiga ku sabaynaya baytariyada

1. Tilmaamaha codsiga ee CMC ee batteriga:
- CMC ee batteriga ayaa leh biyo-biyood wanaagsan, iswaafajin wanaagsan iyo isku dhafka wanaagsan ee budada birta ah ee kala duwan;
-Ayions biraha alaabta waa mid aad u yar, beddelka waa lebis, viscosity waa xasilloon, adhesion waa xoog badan, hufnaanta xal aqueous waa sare, iyo waxqabadka socodka waa wanaagsan yahay;
- Waxa ay wanaajin kartaa madal danabka ah ee baytariga, waxa ay yaraynaysaa caabbinta gudaha ee baytariga, waxa ay yaraynaysaa cadaadiska gudaha batteriga, waxa ay wanaajisaa sifooyinka hawl-galka hadda sare ee baytariga.
2. Shaqada CMC sida xabagta bateriga:
- Isku-xidhka iyo ilaalinta walxaha firfircoon;
- Qaab-dhismeedka gabal tiirar ah oo deggan;
- Ka hortagga roobabka walxaha firfircoon;
- Hagaajinta waxqabadka bixinta lacag bixinta.
