Surfactants: ulwazi olujwayelekile

Surfactants - ekhuthaza ezithinta isimo esishubile ebusweni. Phakathi nokuxhumana zishintshe ketshezi therebetween akhiwa traction. La mandla enza umzimba kuzohluka e ebusweni futhi ingaphakathi (ezijulile) izingqimba. Uma ucabangela isimo ketshezi, kulula ukusungula ukuthi izinhlayiya, okuyinto baqondiswa ohlelweni, kusukela ezinhlangothini ezahlukene sizungezwe amangqamuzana efanayo ezibathintayo. Umphumela wazo zonke amabutho ukuthi isinyathelo molecule zero. Ngakho-ke, uketshezi has ebusweni aphansi kakhulu umthamo inikezwe. Lokhu kuboniswa ngokucacile kubonakala ngesimo amathonsi eyindilinga. Ukuba khona ukungcola compounds ezahlukene nokusaketshezi kubangela ukungezwani surface.

Isakhiwo molecule surfactant

fatty acid kanye alcohols izinhlayiya libe izingxenye ezimbili ezithinta izakhiwo ezahlukene, Nokho, lezi zakhi avamise ukubizwa izakhiwo diphilic. Omunye ingxenye engqamuzaneni imelelwa uchungechunge hydrocarbon, kanye nezinye - amaqembu ehlukene obusebenzayo (acid, hydroxyl, carboxyl, sulfo). The eside iketango hydrocarbon, aba maningi siyofezwa izakhiwo hydrophobic izinhlayiya, bona bazothini ngamanzi buthaka.

compounds Surface-asebenzayo (surfactants) umsuka organic: Bile acid, amaprotheni, insipho, alcohols, ketones, aldehydes, tannins, ketones, njll izinto Surface-ngasebenzi musa kuthinte isimo esishubile ebusweni (isitashi, glucose, fructose).

surfactants Nonionic (surfactant nonionic) - biosoedineniya okusezingeni eliphezulu isisindo yamangqamuzana, amanzi lapho ion musa yakha. Amadamu lezi izinto isinyathelo kanye umkhakha (chemical, zendwangu, umkhiqizo kawoyela), ezifuywayo, yasendlini (usebenzisa ezihlukahlukene insipho zokwenziwa ekhaya) nokucwila, kanye indle nemfucumfucu ye ekulimeni (yokubulala ukhula, nesikhunta, zinambuzane, futhi tomes e njengoba emulsifiers).

Surfactants ukuthola ukusetshenziswa eziningi emnothweni. Emkhakheni wezolimo, bajwayele ukulungiswa emulsions, izimpushana wettable, kanye umkhuba yokuvikela sihlahla izinambuzane. Ucwaningo olwenziwa ukusetshenziswa surfactants ukunciphisa ukuhwamuka ebusweni inhlabathi. Uma amanzi Izingxube inhlabathi yenziwe ngohlobo ezinjalo, ultrathin ifilimu kwakheka kwi ubuso bayo okuyinto evimbela ukuhwamuka umswakama, kodwa ngesikhathi esifanayo ke esiwuhogelayo ngokuphelele futhi kwezulu. Uma inqubo izithelo nemifino surfactant isixazululo, baye eside ukugcina juiciness futhi freshness. Uma wengeza surfactant feed ukwanda kwesisindo izilwane nezinyoni cishe 20% uma kuqhathaniswa ukulawula izilwane.

Surfactants: Ingozi kanye nezinzuzo

Ukungezwani ebusweni kubaluleke kakhulu ngoba izinqubo ukumuncwa kwezakhi esiswini. Ngokwesibonelo, amafutha kanye lipids e ipheshana yesisu iza ngesimo amaconsi. Kwakamuva emulsified emathunjini amancane ngu Bile acid. Kungaleso sikhathi kuphela lapho la amafutha hydrolyzed yi enzyme lipolytic. Isikhathi esining impela, ukuba ngcono zinambuzane ungeze insipho (surfactants). Manipulations zinambuzane ivumela basebenzisane kangcono isinambuzane surface body. Nokho, surfactants ube nemiphumela emihle nje kuphela kodwa futhi omubi emzimbeni. Ngokwesibonelo, e-Ukwakheka imoto ziyingozi kakhulu ejenti yesivini (surfactants), ezifana sodium ne ammonium lauryl sulfate, ammonium futhi sodium laureth sulfate. Kukholakala ukuthi lezi zingxenye kube nomthelela umdlavuza.
