Ngwongwo Rheological nke Ngwọta Methyl cellulose

Njirimara rheological nke ngwọta methylcellulose (MC) dị mkpa maka ịghọta omume ya na arụmọrụ ya na ngwa dị iche iche. The rheology nke ihe onwunwe na-ezo aka na-erugharị ya na nrụrụ àgwà n'okpuru nrụgide ma ọ bụ nsogbu. Njirimara rheological nke ngwọta MC nwere ike imetụta ihe ndị dị ka itinye uche, okpomọkụ, pH, na ogo nke nnọchi.

Viscosity

Viscosity bụ otu n'ime ihe kacha mkpa rheological Njirimara nke MC ngwọta. MC bụ ihe viscous nke ukwuu nke nwere ike ịmepụta ihe ngwọta siri ike mgbe agbazere na mmiri. Viscosity nke ngwọta MC na-adabere na ntinye nke ngwọta, ogo nke nnọchi, na okpomọkụ. N'ihe dị elu nke ngwọta nke ngwọta, nke dị elu viscosity nke ngwọta. Ogo nke nnọchi na-emetụtakwa viscosity nke ngwọta MC. MC nwere ogo dị elu nke nnọchi nwere viscosity dị elu ma e jiri ya tụnyere MC nwere ogo dị ala nke nnọchi. Ọnọdụ okpomọkụ nwekwara ike imetụta viscosity nke ngwọta MC. The viscosity nke MC ngwọta na-ebelata na-abawanye okpomọkụ.

Omume ịkpa agwa

Ngwọta MC na-egosipụta omume na-akpachapụ anya, nke pụtara na viscosity ha na-ebelata n'okpuru nrụgide siri ike. Mgbe a na-etinye nrụgide siri ike na ngwọta MC, viscosity na-ebelata, na-ekwe ka ngwọta na-asọba ngwa ngwa. Ihe onwunwe a dị mkpa na ngwa ebe ihe ngwọta dị mkpa ka ọ na-agba ọsọ ngwa ngwa n'oge nhazi, ma ọ dịkwa mkpa ka ọ nọgide na-enwe oke na nkwụsi ike ya mgbe ọ na-ezu ike.

Omume Gelation

Ihe ngwọta MC nwere ike ịnweta gelation mgbe ọ na-ekpo ọkụ karịa ụfọdụ okpomọkụ. Ihe onwunwe a dabere na ogo nnọchi nke MC. MC nwere ogo dị elu nke nnọchi nwere ogo gelation dị elu ma e jiri ya tụnyere MC nwere ogo dị ala nke nnọchi. Omume gelation nke ngwọta MC dị mkpa na ngwa dị ka mmepụta nke gels, jellies, na desserts.

Thixotropy

Ihe ngwọta MC na-egosipụta omume thixotropic, nke pụtara na viscosity ha na-ebelata ka oge na-aga mgbe ha na-ezu ike. Mgbe a na-etinye nrụgide na-egbu egbu na ngwọta, viscosity na-abawanye.
