I kēia mau lā, ke loaʻa nei iā mākou ka nui o nā nīnau e pili ana i ka hoʻololi ʻana i kā lākou pale acrylic kahiko me kahi pale aniani.
E haʻi mua kākou i ke aniani aniani a me ka PMMA ma ke ʻano he pōkole pōkole:
He aha ke aniani aniani?
Makani anianiHe ʻano kīʻaha palekana i hana ʻia e ka mālama ʻana i ka wela a i ʻole kemika e hoʻonui i kona ikaika i hoʻohālikelike ʻia me ke aniani maʻamau.
Hoʻokomo ka Tempering i nā ʻaoʻao o waho i loko o ka paʻa a ʻo loko i ka ʻāʻī.
Wehe ʻia i loko o nā ʻāpana liʻiliʻi ma mua o nā ʻāpana ʻāʻī e like me ke aniani annealed maʻamau me ka ʻeha ʻole o ke kanaka.
Hoʻohana nui ia i nā huahana uila 3C, nā hale, nā kaʻa, a me nā wahi ʻē aʻe.
He aha ka PMMA?
Polymethyl methacrylate (PMMA), he resin synthetic i hana ʻia mai ka polymerization o ka methyl methacrylate.
ʻO kahi plastik māmā a ʻoʻoleʻa,PMMAhoʻohana pinepine ʻia ma ke ʻano he pani no ke aniani i nā huahana e like me nā puka makani ʻāhaʻi, nā kukui uila, nā hōʻailona hoʻomālamalama, a me nā canopies mokulele.
Kūʻai ʻia ma lalo o nā hōʻailonaPlexiglas, Lucite, a me Perspex.
He ʻokoʻa loa lākou ma nā ʻano ma lalo nei:
| Nā ʻokoʻa | 1.1mm Makaaniani | 1mm PMMA |
| Ka paakiki o Moh | ≥7H | 2H maʻamau, ma hope o ka hoʻoikaika ʻia ≥4H |
| Ka lawe ʻana | 87-90% | ≥91% |
| Ka lōʻihi | Me ka ʻole o ka ʻelemakule a me ke kala hoʻopunipuni ma hope o nā makahiki | E maʻalahi ka ʻelemakule & melemele |
| Palena wela | Hiki ke hoʻomanawanui i ka wela kiʻekiʻe 280 ° C me ka haki ʻole | Hoʻomaka ka PMMA e palupalu ke 80°C |
| Hana hoʻopā | Hiki ke hoʻomaopopo i ka hana paʻi & pale | Loaʻa i kahi hana pale wale nō |
Hōʻike maopopo ʻia ka mea i luna i ka maikaʻi o ka hoʻohana ʻana apale anianiʻoi aku ka maikaʻi ma mua o kahi pale PMMA, manaʻolana e kōkua koke ia i ka hoʻoholo.
