Njirimara nke Methyl Cellulose

Methyl cellulose (MC) bụ cellulose ether nke nwere ọtụtụ ngwa ngwa na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ na ihe owuwu. Ụfọdụ akụrụngwa nke MC gụnyere:

1. Solubility: MC na-agbaze na mmiri ma nwee ike ịmepụta ngwọta doro anya ma kwụsie ike na okpomọkụ ụlọ. Ọ na-esikwa ike na ụfọdụ ihe mgbaze organic, dị ka ethanol na methanol.
2. Viscosity: Viscosity nke ngwọta MC dabere n'ọtụtụ ihe, gụnyere ogo nke nnọchi, ịdị arọ molecular, na itinye uche nke ngwọta MC. Ngwọta MC na-egosipụta omume na-abụghị Newtonian, nke pụtara viscosity na-agbanwe na ọnụego shiee.
3. Ịme ihe nkiri: MC nwere ike ịmepụta ihe nkiri mgbe agbazere ya na mmiri wee kpoo ya. Ihe nkiri nke MC mebere na-agbanwe agbanwe, na-egosipụta, ma nwee ezigbo ihe mgbochi.
4. Nkwụsi ike nke okpomọkụ: MC nwere ezigbo nkwụsi ike nke okpomọkụ ma nwee ike iguzogide okpomọkụ ruo 200 Celsius na-enweghị mmebi dị ukwuu.
5. Ndakọrịta: MC dakọtara na ọtụtụ ihe ndị ọzọ, gụnyere cellulose ethers, starch, na protein ndị ọzọ.
6. Hydrophilicity: MC bụ hydrophilic nke ukwuu, nke pụtara na ọ nwere njikọ siri ike maka mmiri. Ngwongwo a na-eme ka MC baa uru na nhazi ebe njide mmiri dị mkpa, dị ka nri na ngwaahịa nlekọta onwe onye.

N'ozuzu, njirimara nke MC na-eme ka ọ bụrụ ihe dị iche iche nwere ike iji mee ihe n'ọtụtụ ngwa dị iche iche.
