Te Whanaketanga o te Resin Whakamaroke-Mārama i roto i te Ahumahi Tākai Aho LED
I roto i ngā mara o te rama atamai me ngā aho rama whakapaipai, he hurihanga hangarau e arahina ana e ngā kapia whakamaroke rama kei te whakahou i te kete maramara LED. Ehara i te mea ka whakanui ake i te pai o te whakaputanga anake tēnei rauemi hou, engari e whakaatu ana hoki i ngā painga nui o te penapena pūngao me te tiaki taiao.
I te mea ka nui haere te whakamahinga o ngā aho LED i roto i ngā rama whakapaipai, ngā rama whenua, me ngā pūnaha rama atamai, kei te hiahia te mākete ki ngā hangarau tākai hou. Kua āta whakaatuhia e ngā rauemi whakamahana tuku iho ngā herenga pēnei i te puhoi o te whakamaroke, te nui o te pūngao e pau ana, me te iti o te whai huatanga.
Ināianei, ko te whakatutukitanga hou o te hangarau kapia whakamaroke mārama—ina koa ko te whakamahinga o ngā matū whakamaroke mārama UV me ngā matū e kitea ana, kei te kawe mai i ngā otinga hou ki te umanga katoa.
Te Aranga Hangarau: Mai i te Ariā ki te Whakamahinga
Ka taea e ngā kapia whakamaroke mārama te totoka i roto i ngā hēkona i raro i te mārama ultraviolet, i te mārama kitea rānei. Kei roto i ō rātou wāhanga matua ko ngā kapia acrylate, ngā monomer tauhohe, ngā photoinitiators, me ngā momo tāpiri. Ina pāngia e te mārama o ngā roangaru motuhake, ka whakaputahia e ngā photoinitiators ngā rauropi kore utu hohe, ngā kationa rānei, ka whakaoho i te tauhohenga hononga-whiti i waenga i ngā monomer me ngā kapia, ka hanga he paparanga tiaki totoka.
He tino pai tēnei tikanga whakamaroke mō te whakakākahu aho LED—nā te mea ka taea e ngā maramara LED te mahi hei pūtake mārama mō te whakamaroke, e āhei ai te whakakākahu-ā-iwi.
Te Whakatau i ngā Wero o te Ahumahi
He maha ngā wero mō te takai i ngā taiao whakamahinga ahurei o ngā aho LED: me ātete ngā tono o waho ki te makuku, ki ngā rerekētanga pāmahana, me te koroheketanga o te UV; me whai rauemi he tino rere me te uruhanga pai ngā waea uaua; ā, ko te ia o te whakaitiiti e hiahia ana ki ngā rauemi e whakakī katoa ana i ngā āputa iti me te kore e whakararu i te mahi whatu.
Ko ngā take pēnei i te puhoi o te whakapakeke, te nui o te whakapaunga hiko, me te āhua kōwhai o ngā takai kapia epoxy tuku iho, kāore e taea te whakatutuki i ngā hiahia o ngā aho LED hou mō te whakaputa tino whai hua me te pono mō te wā roa.
Te Uara Whaihua o ngā Matū Whakamaroke Mārama
Ko ngā matū whakamaroke mārama matatau kei roto i ngā kohua he kapia acrylate (40-80 wāhanga), he monomer tauhohe (20-40 wāhanga), he kaiwhakaoho whakaahua (1-8 wāhanga), me ngā tāpiringa (1-3 wāhanga). Mā te hanganga kua arotauhia ka taea te whakamaroke katoa i roto i te 2-10 hēkona noa iho i raro i te rama LED kaha-teitei, ka tino whakanui ake i te pai o te whakaputa.
Hei tauira, ko te epoxy acrylate whakarerekētia 61003A, i whakawhanakehia e Ever Ray. Kei tēnei hua te whānuitanga matotoru o te 8,000–18,000 (he pai mō te hanganga o te kōhao), he tere te tauhohenga, he pakari pai rawa atu, ā, he tino pai ngā āhuatanga ārai-kōwhai.
Ngā Painga Hangarau Tino Hiranga
He maha ngā kaha o ngā kapia whakamaroke mārama i roto i ngā tono whakatō aho LED:
Te whai huatanga o te pūngao: Ka taea e te tukanga whakamaroke-mārama te whakaiti i te whakapaunga hiko mā te 20–80%, ka taea ai te whakamaroke tere me te whakanui ake i te kaha whakaputa mō ngā kaihanga.
He pai mō te taiao: Ko te nuinga o ngā matū whakamaroke mārama o ēnei rā kāore he whakarewa me he isocyanates, ā, he iti rawa te ihirangi o te matū waro mimiti (VOC).
Te Mahi: Ka tukuna e te paparanga whakakī kua whakamaroketia he whakawhiti mārama teitei (>99% i roto i te whānuitanga e kitea ana), he ātete UV mō te wā roa, ā, he pai rawa te tiaki miihini me te whakamamae i te ahotea. I tēnei wā, ko ngā momo kohua te nuinga o te wā ka wehea ki te mārama, te āhua mārama, me te kore mārama.
Ngā Tirohanga Whānui o te Mākete
Kei te whānui haere tonu te whakamahinga o ngā kapia whakamaroke mārama i roto i te mara LED. Mai i ngā rama tohu māmā ki ngā hangarau whakaaturanga Mini LED me Micro LED o ēnei rā, kei te piki haere tonu ngā whakaritenga mō ngā rauemi whakakī.
I roto i te rāngai aho LED, kāore ngā kapia whakamaroke mārama e whakarato i te tiaki maramara whai hua engari ka whakapai ake i te pai o te tango mārama, ka whakarei ake i te putanga LED, ka whakaroa hoki i te roa o te ratonga. I te whānui haere tonu o te mākete aho rama atamai me te rama whakapaipai, he tino pai te tirohanga mō te hangarau whakakī whakamaroke mārama.
E whakaatu ana ngā raraunga ahumahi kei te tipu haere te mākete rauemi tākai LED i te tere toharite ā-tau tata ki te 10%, ā, ko te hangarau whakamaroke rama tētahi o ngā wāhanga tino tere te tipu. Ehara i te mea ka whakanui ake tēnei hangarau i te pai o te whakaputa engari ka whakapai ake hoki i te kounga me te pono o te hua, ka tautoko pakari i te whanaketanga pumau o te umanga rama LED.
