Ko te PMMA e kiia ana ko te kiriaku, ko te karanga kiriaku Hainamana i te reo Pākehā, ko te whakamaoritanga ko te plexiglass. Ko te ingoa matū ko te polymethyl methacrylate. Ko te nuinga o te iwi o Hong Kong e kiia ana ko te kiriaku, he whanaketanga wawe o te thermoplastic nui, he mārama pai, he pumau matū me te ātete ki te huarere, he ngawari ki te tae, he ngawari ki te ...tukatuka, he ātaahua te āhua, he whānuitia ngā whakamahinga i roto i te umanga hanga.

Ngā āhuatanga o te rauemi:PMMAHe mārō te kakano o te rauemi, kāore e ngāwari te whati, he tino mārama, he ātete ki te huarere, he ngāwari ki te tae me te hanga, ā, kua whānuitia te whakamahinga i roto i te rauemi tumanako mārama. Ko te kapia acrylate nui ko te polymethyl methacrylate (P2 MMA), e mōhiotia whānuitia ana ko te karāhe waro, i hangaia i te tau 1932.

Mō te hanganga ngota, he kirihou wera raina te Pmma me te tuara macromolecular rite tonu ki te PE. I te nuinga o te wā, ka puta te wae hanganga pmma i te polymerization radical kore utu. Ka whakangaromia e ngā rōpū methyl me te methyl ester i runga i ngā ngota waro te auau ā-wāhi o ngā mekameka ngota, ā, kei roto ngā mekameka macromolecular i te whirihoranga matapōkere, he polymer kore-hīkoi noa.

Hei tāpiritanga, ka totorohia te Pmma ki runga ake i te Tg kia hanga he hanganga āhua tino raupapa, ka taea te whakapai ake i te kaha pānga me te ātete pakaru ahotea o ngā hua, ā, ka taea te whakakore i ngā tauira hiriwa me te whiwhingā hua plexiglass e aro ana.

Ngā whakamahinga o te kiriaku:

He māmā ngā rauemi o te kiriaku, he iti te utu, he ngāwari te hanga, he māmā te tukanga, he iti te utu, me ētahi atu. Nō reira, ka whakamahia whānuitia haeretia, ehara i te mea mō ngā rauemi hanga whare anake, engari mō ngā wāhanga taputapu, ngā rama motuka, ngā karāhe whatu, me ētahi atu.

1, Taputapu ahumahi: pereti mata taputapu, taupoki, me ētahi atu.

2, Ngā wāhi pānuitanga: pouaka rama, papa tohu, pānuitanga, tūāpapa whakaaturanga, me ētahi atu.

3, Ngā whakaurunga kawe waka: ngā tereina, ngā motuka, ngā tekesi me ētahi atu waka, ngā tatau me ngā matapihi, me ētahi atu.

4, Taputapu hauora: ngā incubator pēpi, ngā momo taputapu hauora pokanga, me ētahi atu.

5, Ngā rauemi hanga: ngā matapihi me ngā tatau, ngā tatau me ngā matapihi ārai-oro, ngā taupoki rama, * ngā kiosk, ngā rama hihiko, ngā rama nikau, ngā whakaurunga hauora, te tuanui whakauru, ngā ārai, ngā ārai.
