Shiinaha Surfactant Soo saaraha, Iibiyaha, Warshada

Qaybaha wax soo saarka ee Surfactant , waxaanu nahay shirkado gaar ah oo ka socda Shiinaha , waxaanu nahay iibiyeyaasha / warshadaha , , iyo Amphoteric Surfactants, alaabooyinka tayada sare leh ee jumlada ah ee surfactants R & D iyo wax soo saarka, waxaan leenahay adeegga iibka ka dib iyo taageerada farsamada. Wadashaqeyntiinna filo!

Surfactant, oo sidoo kale loo yaqaan 'surfactant', waa iskudhis si weyn u yareyn kara xiisadda dusha sare ama xiisadda wejiga dhexdooda ee u dhexeysa laba dareere, dareere-gaas, ama dareere-adag. Qaab dhismeedka molecular ee surfactants waa amphiphilic: hal dhamaadka waa koox hydrophilic iyo dhamaadka kale waa koox hydrophobic; kooxda hydrophilic inta badan waa koox polar ah, sida karboxilic acid, sulfonic acid, sulfuric acid, amino ama kooxda amine iyo cusbada ay , kooxaha hydroxyl, kooxaha amide, bond ether, iwm sidoo kale waxaa loo isticmaali karaa sida kooxaha hydrophilic polar; halka kooxaha hydrophobic ay inta badan yihiin silsilado hydrocarbon ah oo aan polar ahayn, sida silsiladaha hydrocarbon oo leh in ka badan 8 atamka kaarboon. Surfactants waxay u kala qaybsan yihiin surfactants ionic (oo ay ku jiraan cationic surfactants, surfactants anionic, amphoteric surfactants), surfactants nonionic, surfactants ka kooban, surfactants kale, iwm.

Unugyada dusha sare waxay leeyihiin amphiphilicity u gaar ah: hal dhamaadka waa koox dabaysha hydrophilic, oo loo soo gaabiyo kooxda hydrophilic, sidoo kale loo yaqaan oleophobic ama kooxda oleophobic, sida - OH- COOH,-SO3H,-NH2. Sababtoo ah dhererka gaaban ee kooxahan shaqeynaya Mararka qaarkood waxaa lagu tilmaamaa inay yihiin madax hydrophilic. Dhamaadka kale waa koox aan cirrid ahayn oo ah lipophilic, oo loo soo gaabiyo kooxda lipophilic, sidoo kale loo yaqaan kooxda hydrophobic ama hydrophobic group, sida R - (alkyl), Ar - (aryl). Sababtoo ah dhererka gaaban ee kooxahan shaqeynaya, waxaa mararka qaarkood loo tixraacaa dabada hydrophobic. Laba nooc oo ka mid ah kooxaha molecular oo leh dhismayaal iyo dhismayaal gebi ahaanba iska soo horjeeda ayaa ku yaal labada daraf ee isla unugga isku midka ah waxayna ku xiran yihiin curaarta kiimikada, samaynta qaab-dhismeedka asymmetric iyo polar, sidaas darteed siinta molecule gaar ah oo leh labadaba hydrophilic iyo oleophilic, laakiin maaha guud ahaan. sifooyinka hydrophilic ama oleophilic. Qaab dhismeedka gaarka ah ee surfactants waxaa caadi ahaan loogu yeeraa "qaab dhismeedka amphiphilic", sidaas darteed molecules surfactant waxaa badanaa loo tixraacaa "molecules amphiphilic".
