He aha te hītori whanaketanga o te kiriaku?

E mōhiotia ana e tātou katoa, ko te kiriaku he mea hanga motuhake ki te plexiglass. He kirihou mārama te karāhe kiriaku, he mama, he ātete hoki ki te pakaru, ā, he mea ātaahua hei whakakapi i te karāhe. Ko ngā momo karāhe i hangaia e te tangata i ahu mai i te tau 3500 BC, ā, neke atu i te kotahi rau tau te roa o te rangahau me te whanaketanga o te kiriaku.

I te tau 1872, i kitea te whakapūhuitanga o te waikawa kiriaku.

I te tau 1880, i mōhiotia te whakapūhuitanga o te waikawa methyl acrylic.

I te tau 1901, i oti te rangahau mō te hanga propylene polypropionate.

I te tau 1907, i whakatau a Tākuta Röhm ki te whakawhānui ake i tana rangahau tohu paerua mō te acrylic acid ester polymerisate, he rauemi mārama, kore tae, me pēhea hoki te whakamahi arumoni.

I te tau 1928, i whakamahia e te kamupene matū Röhm me Haas ā rāua kitenga hei hanga i a Luglas, he karāhe haumaru i whakamahia mō ngā matapihi waka.

Ehara i te mea ko Tākuta Röhm anake te tangata i aro nui ki te karāhe haumaru – i ngā tau tōmua o te tekau tau atu i 1930, i kitea e ngā matū Piritana i Imperial Chemical Industries (ICI) te polymethyl methacrylate (PMMA), e mōhiotia ana ko te karāhe kiriaku. I tapaina e rātou tā rātou kitenga kiriaku ko Perspex.

I whai tata mai ngā kairangahau a Röhm rāua ko Haas i muri; kāore i roa ka kitea e rāua ka taea te whakakotahi i te PMMA i waenga i ngā rau karāhe e rua, ka wehea hei rau karāhe kiriaku. I te tau 1933, i tapaina tēnei e Röhm hei tohu hokohoko ko Plexiglass. I tēnei wā tonu, i hangaia hoki e te kamupene EI du Pont de Nemours & Company (e mōhiotia whānuitia ana ko DuPont) i whānau ki te Hononga o Amerika tā rāua putanga karāhe kiriaku i raro i te ingoa Lucite.

I te Pakanga Tuarua o te Ao, nā tōna kaha me te pakari me te whakawhiti māramatanga, i whakamahia tuatahitia te kiriaku ki te matapihi o mua o ngā waka rererangi me te whakaata o ngā tāke.

I te mutunga o te Pakanga Tuarua o te Ao, ka tūtaki ngā kamupene i hanga kiriaku ki tētahi wero hou: he aha tā rātou e taea ai te hanga i muri mai? I tīmata te puta o ngā whakamahinga arumoni o te karāhe kiriaku i te mutunga o te tekau tau atu i 1930 me te tīmatanga o te tekau tau atu i 1940. Ko ngā āhuatanga ātete ki te pānga me te pakaru i pai ai te kiriaku mō ngā matapihi me ngā matapihi kua whānuitia inaianei ki ngā ārai potae, ngā karāhe o waho o ngā motuka, ngā taputapu tutu pirihimana, ngā ika moana, tae atu ki te "karāhe" huri noa i ngā papa hoki. Kei te kitea hoki ngā kiriaku i roto i te rongoā hou, tae atu ki ngā hononga mārō, ngā whakakapinga katarata, me ngā whakaurunga. Ko tō whare pea kua kī tonu i te karāhe kiriaku: he maha ngā wā ka hangaia ngā mata LCD, ngā karāhe ātete pakaru, ngā anga pikitia, ngā tohu, ngā whakapaipai, ngā taonga takaro, me ngā taonga whare ki te karāhe kiriaku.

Mai i tōna hanganga, kua whakamātauhia te karāhe kiriaku hei whiringa utu iti, pakari hoki mō ngā tono maha.
