Focus on Cellulose ethers

Lisebelisoa tsa mantlha tsa carboxymethyl cellulose ke life?

Carboxymethyl cellulose ke sehlahisoa se nkeloang sebaka sa sehlopha sa carboxymethyl ka selulose. Ho ea ka boima ba eona ba molek'hule kapa tekanyo ea ho fetola, e ka qhala ka ho feletseng kapa ea li-polymers, 'me e ka sebelisoa e le motsoako o fokolang oa acid cation ho arola liprotheine tse sa nke lehlakore kapa tsa motheo.

Carboxymethyl cellulose e ka etsa colloid e phahameng ea viscosity, tharollo, adhesion, thickening, flow, emulsification le litšoaneleho tsa ho hasana; e na le litšobotsi tsa ho boloka metsi, colloid e sireletsang, ho etsa filimi, ho hanyetsa acid, ho hanyetsa letsoai, ho emisoa, joalo-joalo, 'me ha e na kotsi ea physiologically Le litšobotsi tse ling, tse sebelisoang haholo lijong, meriana, lik'hemik'hale tsa letsatsi le letsatsi, petroleum, pampiri, masela, kaho. le masimo a mang.

Sodium carboxymethyl cellulose (CMC) ke sehlahisoa se seholo ka ho fetisisa, se sebelisoang ka ho fetisisa le se loketseng ka ho fetisisa har'a li-cellulose ethers, tse tsejoang e le "industrial monosodium glutamate"!

CMC e nang le viscosity e phahameng le tekanyo e phahameng ea ho fetola e loketse seretse se tlaase-tlaase, 'me CMC e nang le viscosity e tlaase le tekanyo e phahameng ea ho fetola e loketse seretse se phahameng. Khetho ea CMC e lokela ho khethoa ho latela mofuta, sebaka le botebo ba seretse.

Mofuta o mong oa boemo bo phahameng ho feta carboxymethyl cellulose (CMC) ke polyanionic cellulose (PAC), eo hape e leng anionic cellulose ether e nang le boemo bo phahameng ba ho nkela sebaka le ho tšoana. Ketane ea molek'hule e khuts'oane mme sebopeho sa limolek'hule se tsitsitse haholoanyane. E na le khanyetso e ntle ea letsoai, ho hanyetsa acid, ho hanyetsa k'halsiamo, ho hanyetsa mocheso o phahameng le lisebelisoa tse ling, 'me ho qhibiliha ho boetse ho ntlafalitsoe.

Carboxymethyl cellulose e ka sebelisoa liindastering tsohle, 'me carboxymethyl cellulose (CMC) e ka fana ka botsitso bo betere le ho fihlela litlhoko tse phahameng tsa ts'ebetso.
