Emulsion - a mmiri mmiri ngwakọta

Emulsion - a ngwakọta nke bekee. Ọ mejupụtara otu akụrụngwa ezi ahụ unyi anaghị agbasa na ndị ọzọ. Nke a mgwa na-akpọ "chụsasịrị achụsasị adọ". Ọzọ umi - dispersion ọkara. Na mbụ ya akụrụngwa a na-ekesa. "Emulsion" - a okwu nwere a Latin malite. Sụgharịa ọ pụtara "mmiri ara, mmiri ara ehi na". Ka anyị tụlee nke a echiche na ihe zuru ezu.

Isi

N'ihi na abụọ ọ bụla dị mmiri mmiri nke na-adịghị mix ma ọ bụ na-eme na ya, ọ bụ ike ime ka onye na emulsion. Otu n'ime mmiri bụ fọrọ nke nta mgbe mmiri. Ọzọ umi mejupụtara a weakly pola ma ọ bụ na-anọpụ iche ụmụ irighiri (e.g. abụba). The mbụ niile mara na emulsion - bụ mmiri ara ehi. Ebe a, abụba ahụ dispersible n'ime mmiri. The size nke n'onye kasị nta ahụ nke chụgara adọ bụ 1-50 .mu.m, otú emulsions na-coarsely chụgara usoro. Low-ịta mmiri mmiri - unstructured. Mixtures na a akwa ịta - ahaziri. On thermodynamic mgbakwasị mmanụ emulsion - bụ ejighị n'aka usoro. Akụkụ na-adọ ụmụ irighiri mmiri bụ nnukwu, na ngwakọta bụ unstructured.

1. Direct admixture na obere ahụ nke ihe apolar mmiri mmiri na unyi anaghị agbasa na polar adọ (o / w - okwu bụ "mmanụ na mmiri"). N'ihi na ndị dị otú ahụ mixtures nke emulsifiers ike ga-eji nke na-soluble na mmiri, dị ka ahụ nke bitumen. Ha na ụmụ irighiri ihe na-adsorbed n'elu film nke m-adọ, mbenata bụghị nanị erughị ala, ma na-na-eke a siri ike film.
2. Inverse (V / m) ngwakọta, nke na-eji maka mmiri-unyi anaghị agbasa na emulsifier.
