Ko te BMC te whakarāpopototanga o te kirihou polyester thermosetting whakakaha muka karāhe, ā, koinei te momo kirihou thermosetting whakakaha e whakamahia whānuitia ana i tēnei wā.
Ngā Āhuatanga me ngā Whakamahinga o te BMC
He pai ngā āhuatanga ā-tinana, ā-hiko, ā-mīhini hoki o te BMC, nō reira he whānuitia ngā whakamahinga, pērā i te hanga i ngā wāhanga mīhini pērā i ngā paipa whakauru, ngā taupoki takirere, me ngā taupoki poka wai me ngā awhi noa. He whānuitia hoki te whakamahinga i roto i ngā mahi rererangi, te hanga whare, ngā taonga whare, ngā taputapu hiko, me ētahi atu, e hiahia ana ki te ātete ki te rū whenua, te ātete ki te mura, te ataahua me te roa.
Ngā āhuatanga tukatuka BMC
1. Rerenga: He pai te rere o te BMC, ā, ka taea te pupuri i te rere pai i raro i te pēhanga iti.
2. Te Āhua Ora: He tere te tere o te whakaora o te BMC, ā, ko te wā whakaora he 30-60 hēkona/mm ina ko te pāmahana whakakoi he 135-145°C.
3. Te tere whakaheke: He tino iti te tere whakaheke o te BMC, i waenga i te 0-0.5%. Ka taea hoki te whakarite i te tere whakaheke mā te tāpiri i ngā tāpiringa e hiahiatia ana. Ka taea te wehewehe kia toru ngā taumata: te kore whakaheke, te whakaheke iti, me te whakaheke nui.
4. Tae: He pai te tae o te BMC.
5. Ngā Huakore: he roa te wā hanga, ā, he nui te rahi o te pūwero o te hua.
Te whakapūtanga kōpeketanga BMC
Ko te hanga pēhi BMC he tāpiri i tētahi nui o te matū hanga (whakakotahi) ki roto i tētahi pokepoke kua whakamahanahia, ka pēhia, ka whakamahana, kātahi ka whakapakeke, ka hangaia. Ko te tukanga motuhake ko te pauna → whāngai → hanga → whakakī (kei raro i te pēhanga te whakakotahi. Ka rere, ka whakakī i te pokepoke katoa) → whakamaroke → (kua whakamaroke katoa i muri i te pupuri i te pēhanga me te pāmahana kua whakaritea mō tētahi wā) → whakatuwhera i te pokepoke me te tango i te hua → huri i te pūwero, me ētahi atu → hua kua oti.
Ngā tikanga tukanga hanga pēhanga BMC
1. Pēhanga whakakoi: 3.5-7MPa mō ngā hua noa, 14MPa mō ngā hua he nui ngā whakaritenga mata.
2. Te pāmahana pokepokea ai: Ko te pāmahana pokepokea ai te tikanga he 145±5°C, ā, ka taea te whakaheke i te pāmahana pokepokea ai kua whakaritea mā te 5-15°C mō te tangohanga.
3. Te tere o te whakapiri pokepokea ai: ka taea te whakaoti i te whakapiri pokepokea ai pai rawa atu i roto i te 50 hēkona.
4. Wā whakamaroke: Ko te wā whakamaroke o te hua he 3mm te matotoru o te pakitara he 3 meneti, ko te wā whakamaroke me te matotoru o te pakitara he 6mm he 4-6 meneti, ā, ko te wā whakamaroke me te matotoru o te pakitara he 12mm he 6-10 meneti.
