He aha te PMMA? E hia te kaha o te hangarua o te PMMA?

He aha te PMMA, ā, he aha i pai ai mō ngā takai whakapaipai?

He rauemi kirihou wera te PMMA, he tino mārama, e āhei ana ki te uru atu i te 92% o te mārama, he rite tonu te mārama ki te karaihe. I taua wā anō, he pai te ātete o te PMMA ki te huarere, ā, kāore e ngāwari ki te kōwhai, ki te memeha rānei ahakoa te roa o te pānga ki ngā hihi UV. Nō reira, he maha ngā mea whakapaipai papai e whakamahi ana i ngā takai PMMA hei whakarei ake i te kakano me te ataahua o te hua. Haunga tōna ataahua tirohanga, he ātete matū hoki te PMMA, e whakarite ana i te pumau o ngā mea whakapaipai i te wā e rongoa ana.

Ko ngā tono noa mō te takai PMMA ko:

Ngā taupoki pounamu serum: Ka taea e te PMMA te whakaatu i te kakano rite ki te karāhe, e rite ana ki te whakatakotoranga o ngā hua papai pēnei i ngā serum.
Ngā kete paura me ngā takai whakapaipai kirīmi: Mā te ātete pānga o te PMMA ka haumaru ake ngā hua i te wā e kawe ana, e whakamahia ana hoki i ia rā.

He aha te kaha o te PMMA ki te hangarua?

I roto i ngā kirihou wera, he iti noa te kaha o te PMMA ki te hangarua, inā koa nā te mea ka taea e tōna pumau matū te pupuri i ngā āhuatanga ā-tinana pai ahakoa i muri i ngā hangarua maha. Kei raro nei ētahi tikanga hangarua mō te PMMA me ō rātou kaha mō ngā tono takai whakapaipai:

Te hangarua ā-ringa: Ka taea te hangarua ā-ringa i te PMMA mā te kuru, te whakarewa, me ētahi atu mea anō kia hangaia hei takai PMMA hou, hei hanga anō rānei i ētahi atu hua. Heoi anō, tera pea ka paku heke te kounga o te PMMA kua hangarua ā-ringa, ā, me tukatuka pai te whakamahinga anō ki ngā takai whakapaipai papai.

Te hangarua matū: Mā te hangarau pirau matū, ka taea te wawahi i te PMMA ki tōna monomer MMA (methyl methacrylate), ka taea te whakakotahi hei hanga PMMA hou. Mā tēnei tikanga ka mau tonu te parakore me te mārama o te PMMA, ā, ka pai ake ai mō te hanga i ngā takai whakapaipai kounga teitei. Hei tāpiri, he pai ake te hangarua matū ki te taiao i te wā roa atu i te hangarua miihini, engari kāore anō kia whakamahia i runga i te tauine nui i roto i te rāngai whakapaipai nā te nui o te utu me ngā whakaritenga hangarau.

Te hiahia o te mākete mō ngā mahi tauwhiro: I te tipu haere o te tiaki taiao, he maha ngā waitohu ataahua e tīmata ana ki te whakamahi i ngā rauemi PMMA hangarua mō ngā takai. He tata te mahi a te PMMA hangarua ki te rauemi parakore, ā, ka taea te whakaiti i te kai rauemi mata, ka whakaiti i te tapuwae waro. He maha ake ngā waitohu e whakauru ana i te PMMA hangarua ki roto i ā rātou hoahoa hua, e kore e tutuki noa i ngā hiahia ataahua, engari e rite ana hoki ki te ia o te tiaki taiao.
