Carboxymethyl cellulose CMC-Synthetic detergent

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.

Ho hlatsoa kereiti ea CMC ea mohlala: XD, XVD
CMC ke surfactant e nang le lihlopha tsa hydrophilic le hydrophobic.Ke antireabsorbent e sebetsang hantle.CMC e na le litlamorao tse ntle tsa ho tenya, ho qhalakanya le ho etsa emulsifying kamora ho qhibiliha ka metsing.E ka adsorb ho pota-pota likaroloana tsa oli, ho phuthela oli, ho emisa le ho qhala oli ka metsing, 'me ho etsa filimi ea hydrophilic holim'a lihlooho tse hlatsoitsoeng, e le ho thibela oli hore e se ke ea kopana ka ho toba le lihlooho tse hlatsoitsoeng.Haholo-holo ha ho na le lintho tse sebetsang ka har'a sesepa, matla a adsorption a CMC a feta.CMC e na le palo e kholo ea liqoso tse mpe 'me e hlahisa matla a electrostatic repulsion, e leng se etsang hore likaroloana tse mafura li fanyehe hantle' me li qhalakane ka metsing.Ha e bapisoa le CMS, gum, polyvinylpyrrolidone le li-anti reabsorbents tse ling, e na le ts'ebetso ea theko e phahameng.

CMC e na le Ts'ebetso e Ntle ho Kopo ea Sesepa

1. tekanyo e phahameng le e ts'oanang ea ho fetola le ho pepeseha hantle;
2. Dispersibility e ntle ka metsing le khanyetso e ntle ea re adsorption;
3. Ultra high viscosity, botsitso bo botle, thickening e babatsehang le emulsification.
