MMA (Methyl Methacrylate): Monomer Matua mō ngā Polymers Mahi-Tiketike
Ngā Āpure Tono Matua
I roto i te umanga kirihou, e whakamahia whānuitia ana te PMMA mō te hanga pepa mārama, ngongo, me ngā taputapu whatu nā te mea he pai ake ōna āhuatanga whatu. He mārama teitei, he iti te taupū whakaata, he pai hoki te ātete ki te UV, he pai mō ngā tono pēnei i ngā tohu, ngā tūnga whakaaturanga, ngā rama hiku o ngā motuka, me ngā tuanui rererangi. Hei tāpiri, nā te ātete matū pai me te kaha miihini o te PMMA he pai mō ngā taputapu tukatuka kai me ngā taputapu hauora.
I roto i te rāngai paninga me ngā piri, ka whakamahia te MMA hei hanga i ngā momo kapia mahi-teitei. He pai te piri o ēnei kapia, he ātete ki te huarere, he ātete hoki ki ngā matū, ā, he mea whānuitia te whakamahi i roto i ngā paninga whare, ngā paninga motuka, me te whakakī i ngā taputapu hiko. Ko ngā piri e hangai ana ki te MMA, e mōhiotia ana mō ō rātou kaha ki te whakamaroke tere me te kaha ki te piri, e whakamahia whānuitia ana mō te piri i ngā rauemi rakau, whakarewa, me te kirihou.
I roto i te ao rauemi whatu, he rauemi mata matua te MMA mō te hanga muka whatu me ngā karāhe. Nā ōna āhuatanga whatu pai me te ātete ki te huarere, he rauemi tino pai mō ngā tono whatu, tae atu ki ngā taputapu whakawhitiwhiti muka whatu me ngā karāhe whatu mahi teitei. Hei tāpiri, ka whakamahia te MMA i roto i te hanga arataki mārama me ngā pūoko whatu.
I roto i te umanga hiato, ka whakamahia te MMA hei hanga hiato kei roto te kapia methyl methacrylate. He kaha teitei ēnei hiato, he iti te kiato, ā, he tino pai te ātete ki te waikura, nā reira ka whakamahia whānuitia i roto i ngā mahi rererangi, motuka, me ngā taputapu hākinakina. Hei tauira, ka whakamahia ngā hiato kei roto te MMA i roto i ngā parirau rererangi, ngā tinana motuka, me ngā karapu korowha.
