He aha te momo whakaata kirihou ka taea te whakakapi i ngā whakaata karāhe me te kore e rerekē te āhua i ngā wāhi nunui?

Tuatahi, me mārama tātou ki ngā āhuatanga taketake o ēnei rauemi:

1. Whakaata kiriaku (Akirika, Plexiglass, PMMA, Polymethyl Methacrylate)

Painga: he mārama teitei, ka taea te paninga whakaata te taha ke, he pai te pānga tiaki o te paninga whakaata, he ātete ki te pānga (17 x te kaha ake i ngā whakaata karaihe) ā, he ātete ki te pakaru, he māmā, he pakari, he ngāwari hoki.

Huakore: he pakarukaru paku

2. Whakaata kirihou PVC

Painga: iti te utu; he pakeke rawa; ka taea te tapahi me te piko kia rite ki te āhua

Huakore: kāore te rauemi turanga i te mārama, ko te paninga whakaata ka taea anake te waiho ki mua, ā, he iti te mutunga

3. Whakaata Polystyrene (whakaata PS)

He iti te utu. He mārama te rauemi o raro, ā, he pakarukaru, he iti ake te pakari.

4. Whakaata Polycarbonate (whakaata PC)

He māramatanga waenga, he pakari pai (250 ngā wā kaha ake i te karāhe, 30 ngā wā kaha ake i te kiriaku), engari ko te utu nui rawa atu

5. Whakaata karāhe

Painga: he tukanga paninga pakari, he kounga whakaata pai rawa atu, he utu iti, he mata papatahi te nuinga, he rauemi mārō te nuinga, he ātete ki te kakahu me te kore e rakuraku

Ngā ngoikoretanga: he tino pakarukaru, he kore haumaru i muri i te pakaru, he iti ake te ātete ki te pānga, he taumaha ake

Hei whakarāpopototanga, ko te mea tino pai hei whakakapi, ehara i te mea ngāwari ki te whakapēhia, he māmā hoki, ā, kāore e wehi kei pakaru, ko te rauemi kiriaku. Anei ētahi take hei whakamahi i te whakaata kiriaku plexiglass hei rauemi whakakapi mō te karāhe kohuke:

• ● Ātete pānga – He nui ake te ātete pānga o te kiriaku i te karāhe. Mēnā ka pakaru, e kore te kiriaku e pakaru ki ngā wahi iti engari ka ngatata. Ka taea te whakamahi i ngā pepa kiriaku hei kirihou whare kati kōtuhi, hei matapihi whare tākaro, hei matapihi whare iti, hei whakaata Perspex rānei.

ngā matapihi rererangi me ētahi atu hei whakakapi mō te karāhe.

• ● Te whakawhiti mārama – Ka tukuna e ngā pepa kiriaku te 92% o te māramatanga, ko te karāhe ia ka taea te tuku i te 80-90% anake te māramatanga. Pērā i te karaihe, ka pai ake te tuku me te whakaata i te māramatanga o ngā pepa kiriaku i te karāhe pai rawa atu.
• ● He pai ki te taiao – He kirihou pai ki te taiao te kiriaku, ā, he whanaketanga pumau. Whai muri i te hanga o ngā pepa kiriaku, ka taea te hangarua mā te tukanga para. I roto i tēnei tukanga, ka kuruhia ngā pepa kiriaku, kātahi ka whakamahanahia i mua i te whakarewa anō hei tirikara wai. Kia oti te tukanga, ka taea te hanga pepa hou mai i taua mea.
• ● Ātete UV – Mā te whakamahi i ngā pepa kiriaku i waho ka kitea te rauemi ki ngā hihi ultraviolet (UV) teitei rawa. Kei te wātea hoki ngā pepa kiriaku me te tātari UV.
• ● He iti te utu – Ki te mea he tangata e aro nui ana ki te tahua, ka koa koe ki te mōhio he huarahi utu nui ake ngā pepa kiriaku i te whakamahi i te karāhe. Ka taea te hanga pepa kiriaku i te haurua o te utu o te karāhe. He mama ake ēnei pepa kirihou, ā, he ngāwari te kawe, ka iti ake hoki ngā utu tuku.
• ● He ngāwari te hanga me te hanga – He pai ngā āhuatanga hanga o ngā pepa kiriaku. Ina werahia ki te 100 nekehanga, ka taea te hanga ngāwari ki ngā momo āhua tae atu ki ngā pounamu, ngā anga pikitia me ngā ngongo. I a ia e whakamatao ana, ka mau te kiriaku ki te āhua kua hangaia.
• ● Māmā – E 50% te iti iho o te taumaha o te kiriaku i te karāhe, ā, he māmā ake te pupuri. Ki te whakaritea ki te karāhe, he tino māmā te mahi me ngā pepa kiriaku, ā, he ngāwari te kawe mai i tētahi wāhi ki tētahi wāhi.
• ● He rite ki te karāhe te mārama – He āhuatanga tō te kiriaku hei pupuri i tōna māramatanga whatu, ā, he roa te wā e memeha ai. Nā tōna pakari me tōna māramatanga whatu, he pai ake ki te nuinga o ngā kaihanga te whakamahi i ngā pepa kiriaku hei panera mō ngā matapihi, ngā whare kati kōtuhi, ngā matapihi tuanui me ngā matapihi toa.
• ● Haumaru me te kaha – He maha ngā take e hiahia ana koe ki tētahi matapihi kaha rawa atu. E hiahia ana koe mō te kaupapa haumaru, mō te ātete rānei ki te huarere. Tekau mā whitu ngā wā e kaha ake ai ngā pepa kiriaku i te karāhe, ko te tikanga he nui ake te kaha e hiahiatia ana hei ārai i te pakaru o te kiriaku. Kua hangaia ēnei pepa hei whakarato i te haumaru, te tūpato me te kaha i te wā kotahi e pai ai te āhua o te karāhe hei whakakapinga.

I roto i ngā tau, kua nui ake te whakamahinga o te pepa kiriaku i te karāhe i runga i te maha o ngā whakamahinga me ngā āhuatanga o te whakamahi, ā, nā tēnei ka nui ake te ohanga, te roa, me te whai hua o te karāhe kiriaku hei whakakapi mō te karāhe.
