Surfactants: ozi izugbe

Surfactants - a compound na-emetụta n'elu erughị ala. N'oge na mmekọrịta nke mmiri mmiri ụmụ irighiri therebetween ii traction. Nke a na ike ga-adị iche na elu ma n'ime ime (miri) n'ígwé. Ịtụle ala nke mmiri mmiri, ọ dị mfe iru na ahụ, nke na-eduzi n'ime usoro, si dị iche iche n'akụkụ abụọ gbara ya gburugburu otu ụmụ irighiri ihe na-emetụta ha.

The bụghịzi hydrocarbon yinye, ka ukwuu ga-egosipụta hydrophobic Njirimara nke ahụ, ha ga-eme na mmiri na-adịghị ike.

N'elu-n'ọrụ ogige (surfactants) organic si: bile asịd, ndi na-edozi, ncha nke abịanyere, alcohols, ketones, aldehydes, tannins, ketones, wdg N'elu-adịghị ejekwa ozi bekee adịghị emetụta n'elu erughị ala (starch, glucose, fructose).

Nonionic surfactants (nonionic surfactant) - biosoedineniya elu molekụla arọ, mmiri nke ion adịghị na-etolite. The ọdọ a bekee eme ọnụ na ụlọ ọrụ (chemical, akwa, mmanụ mmepụta), anụ ụlọ, ezinụlọ (eji a dịgasị iche iche nke sịntetik detergents n'ụlọ) echekwa, nakwa dị ka nsị wastes si agriculture (ogwu ndi fungicides, ụmụ ahụhụ, na-Tomes na ka emulsifiers).

Surfactants ịhụ ọtụtụ ojiji na aku na uba. Na ugbo oru, ha na-eji maka nkwadebe nke emulsions, wettable ntụ, nakwa dị ka na na omume nke osisi-echebe site pests. Research ekenịmde ke ojiji nke surfactants iji belata evaporation si ala elu. Ọ bụrụ na mmiri ala mixtures dị otú ahụ a mejupụtara, ultrathin film kpụrụ ya elu nke na-egbochi ndị evaporation nke mmiri, ma n'otu oge ya n'ụzọ zuru okè breathable na ọdịda.
