Methyl cellulose (MC) nke e ji ihe sitere n'okike mee
Methyl cellulose (MC) bụ ihe sitere na cellulose, nke bụ polima eke a na-ahụ na mgbidi sel nke osisi. Cellulose bụ otu n'ime ihe ndị dị ndụ kachasị n'ụwa, nke sitere na pulp osisi na eriri owu. A na-emepụta MC site na cellulose site na usoro mmeghachi omume kemịkalụ nke gụnyere nnọchi nke otu hydroxyl (-OH) na molekul cellulose na otu methyl (-CH3).
Ọ bụ ezie na MC n'onwe ya bụ ihe e ji kemịkalụ gbanwee, ihe e ji ya emepụta, cellulose, sitere na ihe ndị sitere n'okike. Enwere ike isi na osisi dị iche iche wepụta cellulose, gụnyere osisi, owu, hemp, na osisi ndị ọzọ nwere eriri. A na-ahazi cellulose ahụ iji wepụ ihe ndị na-adịghị mma ma gbanwee ya ka ọ bụrụ ụdị a pụrụ iji mee ihe maka mmepụta MC.
Ozugbo e nwetara cellulose ahụ, ọ na-eme ka etherification wee tinye otu methyl n'ime ọkpụkpụ azụ cellulose ahụ, nke na-eme ka e nwee methyl cellulose. Usoro a gụnyere iji ngwakọta sodium hydroxide na methyl chloride gwọọ cellulose n'okpuru ọnọdụ a na-achịkwa.
Methyl cellulose nke a na-esi na ya apụta bụ ntụ ntụ ọcha ruo ọcha, enweghị isi, na enweghị ụtọ nke a na-agbaze na mmiri oyi ma na-emepụta mmiri siri ike. A na-ejikarị ya eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, nlekọta onwe onye, na owuwu ya, maka ihe ndị na-eme ka ọ sie ike, na-eme ka ọ sie ike, na-emekwa ka ihe nkiri sie ike.
Ọ bụ ezie na MC bụ ihe e ji kemịkal gbanwee, ọ na-esi na cellulose eke pụta, nke na-eme ka ọ bụrụ ihe a pụrụ ire ere ma dịkwa mma maka gburugburu ebe obibi maka ọtụtụ ojiji.
