Kedu usoro mmepụta nke methylcellulose?

Methylcellulose bụ ụdị polymer nke dabeere na cellulose nke a na-eji na ngwa dị iche iche, gụnyere nri, ọgwụ na ihe ịchọ mma. Ọ bụ ihe na-acha ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ nke na-agbaze na mmiri oyi ma na-emepụta gel mgbe ọ dị ọkụ. A na-emepụta ya site n'ịgwọ cellulose na methyl chloride na sodium hydroxide.

Usoro mmepụta nke methylcellulose gụnyere ọtụtụ usoro. Nzọụkwụ mbụ bụ inweta akụrụngwa, nke na-abụkarị cellulose. Enwere ike nweta cellulose site n'ụdị dị iche iche, dị ka osisi pulp, owu, na eriri osisi ndị ọzọ. A na-ejikwa methyl chloride na sodium hydroxide agwọ cellulose ahụ iji mepụta polymer methylcellulose.

Nzọụkwụ ọzọ bụ ime ka methylcellulose dị ọcha. A na-eme nke a site n'iwepụ adịghị ọcha dị ka lignin, hemicellulose, na ihe ndị ọzọ nwere ike igbochi ihe ndị a chọrọ nke methylcellulose. A na-emekarị nke a site na iji acid ma ọ bụ alkali na-agwọ methylcellulose, ma ọ bụ site na iji usoro a na-akpọ fractionation.

Ozugbo methylcellulose dị ọcha, a na-akpọnwụ ya ma gbanye ya ka ọ bụrụ ntụ ntụ. Nke a ntụ ntụ dị njikere maka ojiji na ngwa dị iche iche.

Enwere ike iji Methylcellulose mee ihe dị ka ihe na-eme mkpụkọ, emulsifier, stabilizer, ma ọ bụ onye na-ahụ maka gelling. A na-ejikwa ya na ngwaahịa nri dị ka ice cream, mgbakwasa salad, na sauces. Na ọgwụ ọgwụ, a na-eji ya dị ka onye na-ekekọta, ihe nkwụsịtụ, na mkpuchi mbadamba. N'ihe ịchọ mma, a na-eji ya eme ihe dị ka thickener, emulsifier, na stabilizer.

Usoro mmepụta nke methylcellulose dị mfe ma dị irè. Ọ bụ ụzọ dị ọnụ ahịa iji mepụta ngwaahịa dị iche iche na-eji ụdị dị iche iche eme ihe. Ọ bụkwa ihe dị mma na nke na-adịghị egbu egbu nke a pụrụ iji mee ihe n'ụdị dị iche iche.
