Dhaqdhaqaaqa dusha sare iyo iska caabbinta biyaha adag ee AES70

Aliphatic alcohol polyoxyethylene ether sodium sulfate (AES) waa koollo jel cad ama huruud khafiif ah, oo si fudud ugu milmi kara biyaha. Waxay leedahay sifooyin nadiifin, emulsification iyo xumbo oo aad u fiican. Si fudud ayaa loo burburin karaa, heerka bayoolojigu waa ka badan yahay 90%. Si ballaaran ayaa loogu isticmaalaa shaambo, dareeraha qubeyska, saabuunta weelka lagu dhaqo, saabuunta isku dhafan iyo qurxinta kale ee dhaqidda; Waxaa loo isticmaalaa warshadaha dharka, wakiilka qoynta, wakiilka nadiifinta, iwm. Anionic surfactant.

Ku saabsan dhaqdhaqaaqa dusha sare iyo iska caabbinta biyaha ee khamriga dufanka leh ee polyoxyethylene ether sodium sulfate (AES):

1. Dhaqdhaqaaqa dusha sare ee AES:

AES waxay leedahay awood qoyn, emulsifiye iyo nadiifin oo xooggan. Xiisadda dusha sare waa hooseysaa, fiirsashada muhiimka ahna waa yar tahay.

Xogtu waxay muujinaysaa in xiisadda dusha sare iyo xoogga qoynta ay saameeyaan dhererka silsiladda kaarboon ee oksaydhka ethylene ee isku xidhan. Xiisadda dusha sare iyo xoogga oksaydhka ethylene ayaa kordha marka la kordhiyo tirada moolalka lagu daray. Intaa waxaa dheer, marka diirimaadka dareeruhu kordho, xiisadda dusha sare ayaa hoos u dhacda, laakiin marka koollada muhiimka ah la gaaro, xiisadda dusha sare mar dambe ma hoos u dhici doonto inkastoo diirimaadku kordho. Qoyaanka oksaydhka ethylene wuu kordhaa marka tirada moolalka lagu daray ay korodho, waxayna yaraataa marka tirada moolalka lagu daray ay korodho.

2. AES iska caabbinta biyaha adag:

AES waxay leedahay iska caabin aad u wanaagsan oo biyaha adag ah, isla markaana la jaanqaadideeda biyaha adag aad bay u fiican tahay. Tusmada xasilloonida ee ion-yada kalsiyum iyo magnesium aad bay u sarreysaa, kala firdhinta saabuunta kalsiyum-na aad bay u fiican tahay.

Sida laga soo xigtay xogta la soo sheegay: silsiladda kaarboonka C12-14 alcohol AES ee biyaha badda 6300ppm, kalsiyumkeeda (biyaha badda) kala firdhisan waa 8%. Biyaha adag ee 330ppm, kala firdhisteeda kalsiyum waa 4%. Tusmada xasilloonida ion-ka kalsiyum > 10000ppmCaCO3. Tusmada xasilloonida ion-ka kalsiyum AES aad bay u sarreysaa, sababtoo ah molecules-keedu waxay leeyihiin dulqaad wanaagsan oo ku saabsan ion-yada kalsiyum (magnesium), taas oo ah, waxay soo saari kartaa cusbada kalsiyum (magnesium) ee dabiiciga ah oo leh ion-yada kalsiyum (magnesium), iyo cusbada kalsiyum (magnesium) ee ay soo saaraan way fududahay in lagu daro kooxaha hydrophilic waxayna ka falceliyaan inay soo saaraan isku-dhafka cusbada kalsiyum (magnesium) ee si fudud u milma. Sidaa darteed, milmida biyaha ee AES aad bay u fiican tahay, waxaana loo isticmaali karaa dhaqidda heerkulka hooseeya. Tijaabooyinku waxay muujinayaan in milmida biyaha ee alcohol C1-14 AES ay ka sarreyso tan alcohol C14-1 ama 16-18 alcohol AES. Milanka AES ee biyaha ayaa kordha marka tirada molar ee ethylene oxide la isku daray ay korodho.
