Ink kauwhango whirinaki UV | Whanonga pai me te whakamahana hoki i te taiao

Te hara kaiwhakarite, e whai ana i te ingoa hoki ko UV resin, he materiale tōmua kei reira e whai ake nei i te mana nui i waenganui i ngā whenua maha no te mea he mea waihanga ahakoa. Ko tēnei momo hara ka whakatupuia ki te hanga o ētahi pūngao whenu i te whakapā mai ki te uru ao (UV) marama, ka huri mai i te rauropi rānei i te rauropi-iti ki te whenu tuhinga, cross - linked. Ko te whakapuawaitanga o te hara UV ka puta noa atu monomers, oligomers, photo - initiators, me ngā whakauru. Ko ngā monomers he mihi iti, he mihi whakawhirinaki e mahi ai hei tahuhu whenu mo te whenu whakapuawaitanga. Hei tirohanga i a rātau i te hunga whakawhanake me te take hoki e taea ana te mahi i roto i te whakapuawaitanga. Ko ngā oligomers, he mihi rahi, ka tukuna te kawe i te wharekura me te whakamahana ki ngā pūnenga matua o te hara i whakapānaia, pērā i te whakamahana, te kohikohinga, me te whakararahi. Ko ngā photo - initiators he take nui ka whakamahia ki te whakapā UV - process. I te whakapā ki te marama UV, ka whakaae ngā photo - initiators i te take me te whakatupu i ngā free radicals. Ka whakatupu ēnei free radicals ka whakapae te whenu me te whakapae i aua whenu ki te hanga i ngā whenu whakahirahira e whai ana ki te whakapūmau i te hara. Ko te koha o te photo - initiator nui rawa hei whakatau i te whakamahara o te hara ki te marama UV me te raumati o te whakapā process. Ka whakauruhia ngā whakauru ki runga i te hara UV hei whakapai i ngā pūnenga mōrearea. Pērā i te mea ka tirohia ngā tae hei whakapai i te tae o te hara, ka whakapai i a ia hei whakamahere mō ngā whakamahere. Ka whakamahia ngā fillers hei whakapai i ngā pūnenga matua, pērā i te whakamahana me te kohikohinga, rānei ka whakaiti i te utu o te hara. Ka tirohia ngā plasticizers hei whakapai i te whakararahi o te hara i whakapānaia, ā, ka whakamahia ngā stabilizers hei whakapai i tana whakamaharatanga ki ngā take tuarohe, pērā i te uru, te marama, me ngā take purea. Kei raro i te hara UV ka whakamahi ngā whenua maha. Ki roto i te whenua pūkorero, ka whakamahiia ki te hanga i ngā pūkorero pūkorero me ngā pūkorero whakapai. Ka whakatakotoria te hara ki ngā take rerekē, ka whakapānaia ki ngā kōhatu taonga rānei ki ētahi take whakamahere, ka whakapānaia ki te marama UV ka hangaia he whanaketanga, whakaaturanga whakapai. Ki roto i te whenua 3D printing, ko te hara UV he take whakahē ki te 3D printers SLA me DLP. Ka whakamahiia hei hanga i ngā tauira 3D whakarerekē me ngā rautaki māku. Ki roto i te whenua coating, ka whakamahiia ngā coating hara UV hei tiaki me te whakapai i te whakaaturanga o ngā take rerekē, pērā i te kahikatoa, te mete, me te rākau, ka tuku mai i ngā pūnenga pērā i te whakamutunga, te whakapuakitanga, me te whakaaturanga whakapai.
