Whakamahinga
Nā te hanganga motuhake o MXDA e whakatau ana he maha ngā āhuatanga ā-tinana me te matū pai rawa atu, nō reira he whānui te whakamahinga. Ka taea te whakamahi i te MXDA me ōna hydride hurihuri hei rongoā mō ngā kapia epoxy, me te mahi rongoā pai rawa atu i te pāmahana rūma, te ātete wera pai, te ātete wai, me te ātete waikura matū. I tua atu, ka taea e rātou te whakaputa i ngā kapia rongoā mārama me te tino oti pai me te iti o te matotoru me te pai o te mahi. I taua wā anō, he takawaenga matū pai nui te MXDA, ka taea te hanga polyamides me ngā waikawa dibasic, ā, ka taea te hanga m-xylene diisocyanate, he monomer o te polyurethane. Ka taea hoki te whakamahi i ōna mowhiti benzene hydride ki te hanga diisocyanates. I tēnei wā, kua whakamahia i roto i te hanga o ngā kaihoko hononga rapa, ngā patu pepeke, ngā kaiwhakaū muka, ngā surfactants, me ētahi atu.
Ko te 1,3-Benzenedimethylamine te nuinga o te wā e whakamahia ana mō te hanga i ngā kapia epoxy mahi-teitei e ātete ana ki te wera, kāore e paitini, e tika ana mō te hanganga i raro i te wai, ā, ka taea te tere te whakamaroke i te wā e whakamahanahia ana. He rauemi mata mō ngā kapia polyurethane me ngā kapia epoxy mahi hangai, ā, e whakamahia ana hoki i roto i ngā mara o ngā āwhina rapa, ngā kirihou photosensitive, ngā patupatu pepeke, ngā paninga, ngā hua nairona, ngā kaiawhina whakaoti muka, ngā aukati waikura, ngā kaiawhina chelating, ngā hinu whakahinuhinu, te tukatuka pepa, me ētahi atu.
E whakamahia ana mō te hanga i ngā matū whakaora kapia epoxy, ngā kirihou whakaahua-ātete, ngā āwhina rapa, ngā kapia polyurethane, ngā paninga, me ētahi atu. Ko te nuinga o te wā e whakamahia ana mō te hanga i ngā matū whakaora kapia epoxy mahi-teitei e ātete ana ki te wera, kāore e paitini, e tika ana mō te hanganga i raro i te wai, ā, ka tere te maroke i te wā e whakamahanatia ana. He rauemi mata mō ngā kapia polyurethane me ngā kapia epoxy mahi hangai, ā, e whakamahia ana hoki i roto i ngā mara o ngā āwhina rapa, ngā kirihou whakaahua-ātete, ngā patu pepeke, ngā paninga, ngā hua nairona, ngā kaihoko whakaoti muka, ngā aukati waikura, ngā kaihoko chelating, ngā hinu whakahinuhinu, te tukatuka pepa, me ētahi atu.
Te Tākai me te Tukunga
25KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
