Polyeter-ka Alkyl: Walax Kiimiko ah oo Ujeeddo Badan leh oo loogu talagalay Adeegsiyada Kala Duwan-1
Goobaha Codsiga ee ugu Muhiimsan
Warshadaha kiimikada, polyether-ka alkyl waxaa loo isticmaalaa walxo ceeriin ah oo loogu talagalay xumbo polyurethane, dhejisyo, shaabadeyn, iyo elastomers. Xumbo polyurethane waxaa si weyn loogu isticmaalaa alaabta guriga, joodariyaasha, kuraasta baabuurta, iyo agabka dahaarka dhismaha. Xabadaha polyurethane iyo shaabadeyn waxaa loo isticmaalaa isku-darka dhismayaasha, baabuurta, iyo aaladaha elektarooniga ah.
Warshadaha dawooyinka, alkyl polyethers waxay u adeegaan sidii maaddooyin iyo emulsifiers daawooyinka, taasoo kor u qaadaysa xasilloonidooda iyo milmidooda. Waxaa sidoo kale loo isticmaalaa in lagu soo saaro xumbo-saare, surfactants, iyo wakiilada qoynta, kuwaas oo si weyn loogu isticmaalo buufinta afka laga qaato, buufinta sanka, dhibcaha indhaha, dhibcaha dhegaha, iyo shaambooyada.
Warshadaha dharka iyo warqadda, polyeters-ka alkyl waxaa loo isticmaalaa jilciyeyaasha, wakiilada ka hortagga istaagga, iyo wakiilada qoynta. Waxay hagaajiyaan jilicsanaanta iyo sifooyinka ka hortagga istaagga ee dharka waxayna kor u qaadaan tayada warqadda iyo hufnaanta wax soo saarka ee sameynta warqadda.
Qaybaha saabuunta iyo alaabada daryeelka shakhsi ahaaneed, polyether-ka alkyl waxaa loo isticmaalaa sidii surfactants iyo emulsifiers. Waxay muujiyaan awood nadiifin wanaagsan, xumbo, xasilin xumbo, qoyn, iyo emulsifier, oo si weyn loogu isticmaalo shaambooyada, dhaqidda jirka, nadiifiyeyaasha gacmaha, iyo saabuunta dharka lagu dhaqo.
Intaa waxaa dheer, polyeters-ka alkyl waxaa loo isticmaalaa sidii nadiifiyayaal iyo saliidayn warshadaha batroolka, iyo sidoo kale qaboojiyeyaasha iyo saliidaha warshadaynta birta.
Habka wax soo saarka ee polyether-ka alkyl wuxuu caadi ahaan ka kooban yahay daaweynta kahor ee bilaabayaasha iyo kiciyeyaasha, falcelinta polymerization-ka ee furitaanka giraanta, iyo tallaabooyinka ka dambeeya habaynta sida dhexdhexaadinta, nuugista, fuuqbaxa, shaandhaynta, iyo kala-soocidda.

Marka la soo koobo
Marka la soo koobo, polyeters-ka alkyl, oo ah walxo kiimiko ah oo badan oo shaqeynaya, waxay door muhiim ah ka ciyaaraan warshado badan. Kaliya ma kordhiyaan waxqabadka badeecada iyo tayada laakiin waxay sidoo kale taageeraan horumarinta warshadaha casriga ah. Iyada oo la marayo horumarka tignoolajiyada ee joogtada ah, rajada codsiga ee polyeters-ka alkyl ayaa sii ballaaran doonta.
