Tsebo ea sodium carboxymethyl cellulose

Thepa ea Sodium Carboxymethyl Cellulose

CMC ke derivative ea cellulose e nang le degree ea glucose polymerization ea 200-500 le degree ea etherification ea 0.6-0.7.Ke phofo e tšoeu kapa e bosoeu kapa ntho e nang le fiber, e sa nkhang hamonate ebile e le hygroscopic.Tekanyo ea ho nkela sebaka sa sehlopha sa carboxyl (tekanyo ea etherification) e khetholla thepa ea eona.Ha tekanyo ea etherification e ka holimo ho 0.3, e qhibiliha ka tharollo ea alkali.Viscosity ea tharollo ea metsi e khethoa ke pH le tekanyo ea polymerization.Ha tekanyo ea etherification e le 0.5-0.8, e ke ke ea theoha ka acid.CMC e qhibiliha habonolo ka metsing 'me e fetoha tharollo e hlakileng ea viscous metsing,' me viscosity ea eona e fapana le tharollo ea mahloriso le mocheso.Thempereichara e tsitsitse ka tlase ho 60 ° C, 'me viscosity e tla fokotseha ha e futhumetse nako e telele mocheso o ka holimo ho 80°C.

Boholo ba tšebeliso ea sodium carboxymethyl cellulose

E na le mesebetsi e fapaneng e kang ho teteka, ho emisa, ho emulsifying le ho tsitsisa.Tlhahisong ea lino-mapholi, e sebelisoa haholo-holo e le setenya bakeng sa lino tse nang le lero la mofuta oa pulp, joalo ka emulsification stabilizer bakeng sa lino tse nang le protheine le joalo ka stabilizer bakeng sa lino tsa yogurt.Tekanyetso hangata ke 0.1% -0.5%.
