Methyl cellulose (MC) nke ngwaahịa sitere n'okike

Methyl cellulose (MC) bụ ihe sitere na cellulose, nke bụ polymer eke dị na mgbidi cell nke osisi.Cellulose bụ otu n'ime ogige ndị dị n'ụwa kachasị ukwuu, nke sitere na pulp osisi na eriri owu.A na-emepụta MC site na cellulose site na usoro mmeghachi omume kemịkalụ nke gụnyere ngbanwe nke otu hydroxyl (-OH) na cellulose molecule na otu methyl (-CH3).

Ọ bụ ezie na MC n'onwe ya bụ ngwakọta kemịkalụ gbanwetụrụ, akụrụngwa ya, cellulose, sitere na isi mmalite eke.Enwere ike ị nweta cellulose site na ihe ọkụkụ dị iche iche, gụnyere osisi, owu, hemp, na osisi ndị ọzọ nwere eriri.Cellulose na-enweta nhazi iji wepụ ihe ndị na-adịghị ọcha ma gbanwee ya ka ọ bụrụ ụdị eji eme ihe maka mmepụta nke MC.

Ozugbo enwetara cellulose, ọ na-enweta etherification iji webata ìgwè methyl na ọkpụkpụ azụ cellulose, na-eme ka e nwee methyl cellulose.Usoro a gụnyere ịgwọ cellulose na ngwakọta nke sodium hydroxide na methyl chloride n'okpuru ọnọdụ a na-achịkwa.

Ihe si na ya pụta bụ methyl cellulose bụ ọcha na-acha ọcha, enweghị isi, na ntụ ntụ na-enweghị ụtọ nke na-agbaze n'ime mmiri oyi ma mepụta ngwọta viscous.A na-eji ya eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, nlekọta onwe onye, ​​na ihe owuwu, maka ihe na-eme ka ọ sie ike, na-eme ka ọ dị ike, na-emepụta ihe nkiri.

Ọ bụ ezie na MC bụ ngwakọta kemịkalụ gbanwetụrụ, a na-enweta ya site na cellulose eke, na-eme ka ọ bụrụ ihe na-emebi emebi na nhọrọ gburugburu ebe obibi maka ọtụtụ ngwa.
