Surfactants: onse mudziwe

Surfactants - pawiri zokhudza mavuto padziko. Pa mogwirizana kwa mamolekyulu madzi therebetween anapanga samatha. mphamvu adzakhala osiyana mu pamwamba ndi zigawo mkati (kwambiri). Poganizira boma la madzi, n'zosavuta kukhazikitsa kuti particles, amene akuuzidwa mu dongosolo, ku mbali zosiyana atazungulira mamolekyulu chomwecho chimene kuwakhudza. The chotsatira cha mphamvu zonse kuchita molekyulu ndi ziro. Choncho, madzi ali pamwamba wotsikitsitsa kwa buku anapatsidwa. Izi kuonekera mu mawonekedwe a madontho ozungulira. Pamaso zosafunika mankhwala osiyanasiyana mu madzi amachititsa mavuto padziko.

Kapangidwe ka tinthu surfactant

mafuta zidulo ndi alcohols particles zigwirizana ndi mbali ziwiri zomwe ndi katundu osiyana Komabe, mankhwala amenewa nthawi zambiri amatchedwa nyumba diphilic. Mbali ina ya molekyulu ikuyimiridwa ndi unyolo hydrocarbon, ndi zina - osiyana magulu zinchito (kwa amino, hydroxyl, carboxyl, sulfo). The yaitali hydrocarbon unyolo, wamkulu adzalamulira katundu hydrophobic particles, iwo angachite ndi madzi ofooka.

Pamwamba-yogwira mankhwala (surfactants) chiyambi organic: ya ndulu zidulo, mapuloteni, sopo, alcohols, ketones, aldehydes, tannins, ketones, etc. Pamwamba-anafooka zinthu sizikukhudzana ndi mavuto padziko (wowuma, shuga, fructose).

surfactants Nonionic (nonionic surfactant) - biosoedineniya mkulu maselo kulemera, madzi amene ayoni musati kupanga. Malo zinthu zimenezi zinthu pamodzi ndi makampani (mankhwala, nsalu, mafuta kupanga), m'banja, banja (ntchito zosiyanasiyana detergents kupanga kunyumba) limalephera, komanso zimbudzi zinyansi ku ulimi (herbicides, fungicides, tizirombo, komanso Tomes mu monga emulsifiers).

Surfactants kupeza ntchito zambiri mu chuma. Mu gawo la ulimi, iwo amagwiritsa ntchito yokonza emulsions, wettable ufa, komanso kuchita chitetezo zomera ku tizirombo. Research ochitidwa ndi ntchito surfactants kuchepetsa evaporation kwa nyemba zanu. Ngati madzi nthaka zosakaniza ndi zikuchokera amenewa, ultrathin filimu anapanga pamwamba pake amene kumathandiza evaporation cha chinyezi, koma pa nthawi yomweyo izo mwangwiro breathable ndi mpweya. Ngati ndondomeko ya zipatso ndi ndiwo zamasamba surfactant njira, iwo akhala kusunga juiciness ndi kutsitsimuka. Pamene kuwonjezera surfactant kwa chakudya kuwonjezeka kunenepa kwa nyama ndi mbalame ndi pafupifupi 20% poyerekeza ndi nyama kulamulira.

Surfactants: Vuto ndi ubwino

Mavuto pamwamba kwambiri kuti njira ya mayamwidwe wa zakudya m'matumbo. Mwachitsanzo, mafuta ndi lipids kapepala kakuti m'mimba akubwera mu maonekedwe a m'malovu. Recent emulsified mu intestine aang'ono zidulo ya ndulu. Pakumala mafuta awa hydrolyzed ndi michere lipolytic. Nthawi zambiri, kusintha Mwachangu wa tizilombo anawonjezera sopo (surfactants). Mwai tizirombo amalola bwino kucheza ndi thupi pamwamba tizilombo. Komabe, surfactants ndi zotsatira osati zabwino komanso zoipa m'thupi. Mwachitsanzo, mu shampu zikuchokera ndi zoipa thobvu wothandizila (surfactants), monga soda ndi ammonium lauryl sulphate, ammonium ndi sodium wochuluka laureth sulphate. Akukhulupirira kuti zigawo izi kukhudza carcinogenic.
