Ko te 403 polyether polyol he polyether polyol i synthesed by direct polymerization of ethylenediamine with epichlorohydrin as the initiator.
HYW403
HUAYU
Ko nga ahuatanga: Ko te 403 polyether polyol he polyether polyol i synthesized na roto i te polymerization tika o te ethylenediamine me te epichlorohydrin hei timata.
Tono: 403 polyether te nuinga whakamahia i roto i te rehu rauemi polyether hiato, ka taea e whakatere te reira i te tauhohenga ripeka-hononga pahuka, te whakapai ake i te kaha o ngā hua pahuka i, a taea hoki te whakamahi whānui i te reira i roto i polyurethane pahuka i mo pipelines, whakamahana wai solar, pouaka whakamātao, me ētahi atu, hanga reira he kaihoko ripeka-hono pai.
Te Taapaki: Ka mau ki roto i te 200kg pahū rino Te rokiroki me te kawe waka: 403 polyether te kaha o te hygroscopicity, me penapena ki roto i nga ipu kua hiri ki te waahi maroke me te hauhautanga, kia kore e pa ki te ra. Ko te oranga o te papa kaore i te iti iho i te 6 marama, karekau tenei hua e kiia he morearea.
