Ua kapa ʻia hoʻi ʻo PMMA he acrylic, ʻo ia ka inoa acrylic Kina ma ka ʻōlelo Pelekania, ʻo ka unuhi maoli ʻo plexiglass. ʻO ka inoa kemika he polymethyl methacrylate. ʻO ka poʻe Hong Kong i kapa nui ʻia he acrylic, he hoʻomohala mua ia o kahi thermoplastic koʻikoʻi, me ka transparency maikaʻi, ke kūpaʻa kemika a me ke kūpaʻa i ka wā, maʻalahi ke kala, maʻalahika hana ʻana, nani ke ʻano, ma ka ʻoihana kūkulu hale he ākea nā noi.

Nā ʻano mea:PMMAHe ʻano paʻakikī ka mea, ʻaʻole maʻalahi e haki, ʻike maopopo loa, kūpaʻa maikaʻi i ka wā, maʻalahi ke kala a me ka hoʻoheheʻe ʻana, a pēlā aku, ua hoʻohana nui ʻia i ka mea aniani moakaka. ʻO ka resin acrylate koʻikoʻi ʻo polymethyl methacrylate (P2 MMA), i ʻike nui ʻia ʻo ke aniani organik, hana ʻoihana i ka makahiki 1932.

Ma ke ʻano o ke ʻano molekala, ʻo Pmma kahi thermoplastic linear me kahi iwi kuamoʻo macromolecular e like me ko PE. ʻO ka maʻamau, ʻo ka polymerisation radical manuahi e hua mai i ka ʻāpana kūkulu pmma. Hoʻopau nā hui methyl a me methyl ester ma nā ʻātoma kalapona i ka maʻamau spatial o nā kaulahao molekala, a aia nā kaulahao macromolecular i kahi hoʻonohonoho random, ʻo ia ka polymer hele wāwae ʻole maʻamau.

Eia kekahi, ua hohola ʻia ka Pmma ma luna o Tg e hana i kahi ʻano mokuʻāina i hoʻonohonoho pono ʻia, hiki ke hoʻomaikaʻi i ka ikaika hopena a me ke kūpaʻa ʻana o ka stress cracking o nā huahana, a hiki ke hoʻopau i nā ʻano kālā a loaʻa.nā huahana plexiglass i kuhikuhi ʻia.

Nā hoʻohana ʻana o ka acrylic:

Loaʻa i ka acrylic nā pono o ka mea māmā, ke kumu kūʻai haʻahaʻa, maʻalahi ke hana, ke kaʻina hana maʻalahi, ke kumukūʻai haʻahaʻa, a pēlā aku. No laila, ua hoʻohana nui ʻia, ʻaʻole wale i nā mea kūkulu hale, akā ua hoʻohana nui ʻia hoʻi i nā ʻāpana mea kani, nā kukui kaʻa, nā aniani optical, a pēlā aku.

1, Nā lako hana ʻoihana: papa ʻili o ka mea kani, uhi, a pēlā aku.

2, Nā hale hoʻolaha: pahu kukui, papa hōʻailona, ​​​​hōʻailona, ​​​​kū hōʻike, a pēlā aku.

3, Nā pono halihali: nā kaʻaahi, nā kaʻa, nā taxi a me nā kaʻa ʻē aʻe, nā puka a me nā puka makani, a pēlā aku.

4, Nā lako lapaʻau: nā incubators pēpē, nā mea hana lapaʻau ʻoki kino like ʻole, a pēlā aku.

5, Nā mea hana hale: nā puka makani a me nā puka, nā puka a me nā puka makani keʻokeʻo, nā uhi kukui, * nā kiosks, nā kukui fluorescent, nā kukui pama, nā pono hoʻomaʻemaʻe, ke kaupaku i hoʻohui ʻia, nā ʻāpana, nā pale.
