ārai mate

ngā āhuatanga matū

He momo whakaū mārama te ngongo hihi ultraviolet, ka taea te mimiti i te hihi o te rā me te pūtake mārama fluorescent i roto i te wāhanga hihi ultraviolet, engari kāore ia e rerekē.
Nā te mea he nui te hihi ultraviolet e kino ana ki ngā mea tae, ko tōna roangaru he 290-460 nanometer, ā, mā te tauhohenga matū Redox ka pirau ngā ngota tae, ka memeha.
He huarahi ā-tinana, he huarahi matū hoki hei ārai i te kino o ngā tae mai i te mārama UV kino.
Anei tētahi whakataki poto ki te tikanga matū, arā, te whakamahinga o ngā mimiti UV hei tiaki i te mea, hei ārai whai hua rānei, hei whakaiti rānei i tōna whakangaromanga o te tae.
Me whai ngā ārai UV i ngā āhuatanga e whai ake nei
(1) ka taea te mimiti kaha i te mārama ultraviolet (ina koa ko te roanga ngaru o te 290-400nm); (2) He pai te pumau o te wera, ahakoa i roto i te tukatuka kāore e rerekē i te wera, he iti te pikinga o te wera; He pai te pumau matū, kāore he tauhohenga kino ki ngā wāhanga rauemi o te hua; (4) He pai te whakaranu, ka taea te horapa ōrite i roto i te rauemi, kāore he huka, kāore he waikura; (5) He pai te pumau o te photochemical o te mimiti, kāore e pirau, kāore e rerekē te tae; ⑥ Kore tae, kāore he paitini, kāore he kakara; ⑦ ātete ki te horoi rumaki; ⑧ He iti te utu, he ngāwari ki te tiki; 9. Kāore e rewa, kāore rānei e rewa i roto i te wai.
Ka taea te whakarōpū i ngā mea mimiti UV ki ngā rōpū e whai ake nei i runga i tō rātou hanganga matū: salicylate esters, phenylketones, benzotriazoles, substituted acrylonitrile, triazines me ngā amines aukati.

Te whakataki me ngā āhuatanga o te hua

Ko te mea mimiti hihi ultraviolet te momo whakaū rama kotahi e whakamahia whānuitia ana, e ai ki tōna hanganga ka taea te wehewehe ki ngā esters salicylate, benzophenone, benzotriazole, acrylonitrile whakakapi, triazines, me ētahi atu. Ko te nuinga o te tono ahumahi ko te benzophenone me te benzotriazole. Ko te mea tinei he matatini whakarewa, pērā i te matatini nickel divalent, he maha ngā wā ka mimiti hihi ultraviolet, ā, he pānga tahi, ko te mea mimiti hihi ultraviolet he momo whakaū rama, ka taea te mimiti i te rā me te pūtake rama fluorescent i roto i te wāhanga hihi ultraviolet, ā, kāore e rerekē.
Nā te mea he nui te hihi ultraviolet e kino ana ki ngā mea tae, ko tōna roangaru he 290-460 nanometer, ā, mā te tauhohenga matū Redox ka pirau ngā ngota tae, ka memeha.
He huarahi ā-tinana, he huarahi matū hoki hei ārai i te kino o ngā tae mai i te mārama UV kino.
Anei tētahi whakataki poto ki te tikanga matū, arā, te whakamahinga o ngā mimiti UV hei tiaki i te mea, hei ārai whai hua rānei, hei whakaiti rānei i tōna whakangaromanga o te tae.

whakamahi

Ka taea e ia te mimiti i te mārama ultraviolet me te roangaru o te 270-380 nm, e whakamahia ana mō te polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin me te cellulose resin, me ētahi atu. He pai mō ngā rauemi photosensitive pērā i te kiriata tae, te kiriata tae, te pepa tae me te polymer, me ētahi atu. He tino pai mō ngā hua mārama me te mārama kore tae; Mō te mimiti kaha, he pai te mahi ultraviolet absorber.

mōkihi me te kawe

B. Ka taea te whakamahi i tēnei hua, 25KG, BAERRLS.
C. Penapenahia kia hiri ki roto i te wāhi hauhautanga, maroke, me te hauhautanga. Me hiri rawa ngā ipu i muri i ia whakamahinga i mua i te whakamahinga.
D. Me hiri pai tēnei hua i te wā e kawe ana kia kore ai e uru te makuku, te kawakore me te waikawa kaha, te ua me ētahi atu poke.
