Whakamahinga
Ko te waipiro Tetrahydrofurfuryl (THFA) e kiia whānuitia ana he whakarewa "kakariki" i roto i ngā mahi ahumahi. He whakarewa iti te utu, he pirau te THFA, e whakamahia ana hei wairewa tauhohe mō ngā kapia epoxy, ā, he whakarewa pai hoki mō te maha o ngā rongoā me ngā whakakorikori e whakamahia ana i roto i ngā hanganga epoxy. E whakamahia ana hoki i roto i ngā mahi e whai ake nei:
Ka pāngia te waipiro Tetrahydrofurfuryl e te hauwaiora chemoselective i whakakorikoria e te Rh/SiO2 i whakarerekētia ki ngā momo ReOx hei whakaputa i te 1,5-pentanediol. Ka pāngia hoki e te tauhohenga tāpiri momo-Michael i raro i te lanthanum me te maleate hei hanga i te waikawa alkoxybutanedioic.
I whakamahia te waipiro Tetrahydrofurfuryl hei whakarewa taurite i te taupū whakaata hei whakarite i te whakatārewatanga porowhita mārō o ngā matūriki silica mō ngā inenga rheological.
Ka taea te whakamahi i te waipiro Tetrahydrofurfuryl hei paerewa tohutoro tātari mō te ine i te nui o te matū tātari i roto i ngā kiore me te kakara paoa mai i te kiri raihi mā te whakamahi i ngā tikanga chromatography.
Tākai:
220KG/Pahu
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Penapena ki te wāhi hauhautanga, maroke hoki, kaua e tukua kia whiti te rā
