Tlhaloso e Khutšoanyane:

Carboxymethylation reaction ke e 'ngoe ea mahlale a etherification.Ka mor'a carboxymethylation ea cellulose, carboxymethyl cellulose (CMC) e fumanoa.Tharollo ea eona ea metsi e na le mesebetsi ea ho tiisa, ho etsa filimi, ho kopanya, ho boloka metsi, tšireletso ea colloidal, emulsification le ho emisoa.E sebelisoa haholo indastering ea peterole, lijo, meriana, masela le ho etsa pampiri.Ke e 'ngoe ea li-cellulose ethers tsa bohlokoa ka ho fetisisa.Ka tsebo ea rona ea nako e telele ea khoebo ea lihlahisoa tsa lik'hemik'hale, na re u fa keletso ea litsebi mabapi le lihlahisoa le litharollo tse etselitsoeng morero oa hau o khethehileng.Re thabela ho u thusa ho khetha lisebelisoa tse u loketseng. Tobetsa feela ho fumana lits'ebetso indastering ea hau: CMC lijong, petroleum, khatiso le ho daea, lirafshoa, sesepa sa meno, beneficiation e phaphametseng, betri, ho roala, putty powder le papermaking.
