Ko tētahi mea nui hei whakaaroaro māu i te wā e whiriwhiri ana i ngā karaihe ko te rauemi o te karaihe.
Ko te kirihou me te polycarbonate ngā rauemi noa e whakamahia ana i roto i ngā mōhiti tirohanga.
He mama, he pakari te kirihou, engari he matotoru ake.
He angiangi ake te polycarbonate, ā, he ārai i te hihi o te rā, engari he ngāwari te rakuraku, ā, he nui ake te utu i te kirihou.
He āhuatanga motuhake tō ia rauemi arotahi, ā, he pai ake mō ētahi reanga, hiahia me ngā momo āhua noho. I te wā e whiriwhiri ana i tētahi rauemi arotahi, he mea nui kia whakaarohia:
●Taumaha
●Ātete pānga
●Ātete ki te rakuraku
●Matotoru
●Te parenga ki te hihi ultraviolet (UV)
●Te utu
He tirohanga whānui mō ngā karaihe kirihou
E mōhiotia ana hoki ngā karaihe kirihou ko te CR-39. Kua whānuitia te whakamahinga o tēnei rauemi i roto i ngā mōhiti kanohi mai i te tekau tau atu i 1970, ā, he mea rongonui tonu i waenga i te hunga e mau ana i ngā mōhiti kanohi nā te meatōnaHe iti te utu, he roa hoki te mau. Ka taea te tāpiri ngāwari i te paninga ātete-rakuraku, he tae kanapa me te paninga tiaki ultraviolet (UV) ki ēnei karaihe.
●Māmā –Ki te whakaritea ki te karaihe karauna, he mama te kirihou. He pai te mau i ngā mōhiti he karaihe kirihou mō te wā roa.
●He māramatanga whatu pai –He mārama pai ngā karāhe kirihou. Kāore e nui te whakapōturi o te tirohanga.
●Pakeke –He iti ake te tūponotanga o te pakaru, te pakaru rānei o ngā karaihe kirihou i te karaihe. Nā tēnei he kōwhiringa pai ēnei mō te hunga hihiko, ahakoa kāore i te rite te ātete ki te pakaru ki te polycarbonate.
●He iti ake te utu –He iti ake te utu o ngā karāhe kirihou i te polycarbonate.
●Parenga UV wāhanga –He iti noa te parenga o te kirihou mai i ngā hihi UV kino. Me tāpiri he paninga UV hei tiaki 100% mēnā kei te whakaaro koe ki te mau i ngā mōhiti ki waho.
He tirohanga whānui mō ngā karaihe polycarbonate
He momo kirihou ātete-pānga te polycarbonate e whakamahia whānuitia ana i roto i ngā mōhiti kanohi. I whakaurua mai ngā karaihe polycarbonate arumoni tuatahi i te tekau tau atu i 1980, ā, i tere te piki haere o te rongonui.
Tekau ngā wā ka nui ake te ātete o tēnei rauemi karaihe ki te pānga i te kirihou. Nā reira, he maha ngā wā ka tūtohutia kia whakamahia mō ngā tamariki me ngā pakeke hohe.
●Pūmau –Ko te polycarbonate tētahi o ngā rauemi tino kaha, tino haumaru hoki e whakamahia ana i ēnei rā mō ngā mōhiti. He maha ngā wā e tūtohutia ana mō ngā tamariki nohinohi, ngā pakeke hohe, me te hunga e hiahia ana ki ngā mōhiti haumaru.
●Angiangi, māmā hoki –E 25 ōrau te angiangi o ngā karāhe polycarbonate i te kirihou tuku iho.
●Te parenga UV katoa –Ka ārai te polycarbonate i ngā hihi UV, nō reira kāore he take ki te tāpiri i tētahi paninga UV ki ō mōhiti. He kōwhiringa pai ēnei karāhe mō te hunga e noho roa ana i waho.
●E taunakihia ana te paninga ātete-rakuraku –Ahakoa he pakari te polycarbonate, he ngāwari tonu te rakuraku o te rauemi. E taunakihia ana kia pania he paninga ātete-rakuraku kia roa ake ai te ora o ēnei karaihe.
●E taunakihia ana te paninga ārai-whakaata –Ka kite ētahi tāngata he nui ake ā rātou rongoā karaka i ngā whakaata o te mata me ngā tae e piri ana ina mau ana i ngā karaihe polycarbonate. E taunakihia ana kia pania he paninga ārai-whakaata hei whakaiti i tēnei pānga.
●Te tirohanga pōrearea –Ka taea e te polycarbonate te whakapōturi i te tirohanga taha mō te hunga he kaha ake ā rātou rongoā.
●He nui ake te utu –He nui ake te utu o ngā karaihe polycarbonate i ngā karaihe kirihou.
