CAS 9032-42-2 HEMC mo nga kaitohu hanga

Whakaahuatanga Poto:

1. Ko te HEMC hydroxyethyl methyl cellulose he mea hanga mai i te cellulose miro tino ma. I muri i te maimoatanga alkali me te etherification motuhake ka waiho hei HEMC. Kaore he momona a te kararehe me etahi atu mahinga kaha.

2. Ko te ahua o te HEMC he matūriki ma, he paura ranei, kaore he kakara me te koretake. He hygroscopic a kaore e taea te rewa i roto i te wai wera, acetone. te waihono me te toluene. Whai muri i te pupuhi i roto i te wai makariri ki roto i te otinga koroi, kaore te paheketanga e pangia e te uara PH. He rite ki te methyl cellulose, engari na te kaha haere o nga roopu hydroxyethyl, he manawanui, he ngawari ake te wairewa i te wai, he teitei ake te mahana whakamahana.
