Methoxypolyethylene Glycols CAS 9004-74-4

Ko te polyethylene glycol monomethyl ether he hua o te polyethylene glycol. He wairewa i roto i te wai, te waiwaro me te nuinga o nga whakarewa pararopi polar. He iti ake te pahekeheke i te glycerol, he mea matū pumau, kaore e ngawari ki te hauwai me te whakangaro, me te kaha o te hydrophilicity. He iti te pehanga kohu, he pumau ki te wera. Ka whakamahia hei whakakao me te whakahinuhinu i roto i te umanga ta kakano me te tae tae me te umanga matū o ia ra. I roto i te ahumahi rauemi hanga, ka whakamahia hei rauemi mata mo nga whakaheke wai ciment me nga kaihoko whakapakari. Ko te waikawa polycarboxylic waikawa nui te whakaheke wai i whakahiatohia ma te whakamahi i tenei rauemi mata he kaha te kaha ki te pupuri i te whakamararatanga o nga matūriki ciment, ka whai hua te hua o te iti o te inenga, te tere o te whakaheke i te wai, te pai o te whakapakari, te mauroa, kaore he pirau o te rino. tutaki me te atawhai taiao. Ka taea te whakamahi i roto i nga mahi teitei, te kaha teitei (C60 ranei i runga ake) raima hokohoko mo te whakauru i runga i te waahi me te kawe tawhiti.
