ʻAkika Methacrylic (ʻakika 2-Methyl-2-propenoic)
| Nā ʻano kemika | ʻO ka waikawa Methacrylic, i hoʻopōkole ʻia ʻo MAA, he hui organik. ʻO kēia wai ʻūlū ʻole, he waikawa carboxylic me kahi ʻala ʻawaʻawa. Hiki ke hoʻoheheʻe ʻia i ka wai mahana a hui pū ʻia me ka hapa nui o nā mea hoʻoheheʻe organik. Hana ʻia ka waikawa Methacrylic ma kahi ʻoihana ma ke ʻano he mea mua i kāna mau esters, ʻoiai ʻo ka methyl methacrylate (MMA) a me ka poly(methyl methacrylate) (PMMA). He nui nā hoʻohana o nā methacrylates, ʻoi aku ka nui i ka hana ʻana i nā polymers me nā inoa kālepa e like me Lucite lāua ʻo Plexiglas. Loaʻa maoli ka MAA i nā liʻiliʻi liʻiliʻi i ka ʻaila o ka chamomile Roma. | |
| Nā noi | Hoʻohana ʻia ka waikawa Methacrylic i ka hana ʻana i nā resins methacrylate a me nā plastics. Hoʻohana ʻia ia ma ke ʻano he Monomer no nā resins nui a me nā polymers, synthesis organik. Hoʻokumu ʻia ka hapa nui o nā polymers ma luna o nā esters o ka waikawa, e like me ka methyl, butyl, a i ʻole isobutyl esters. Hoʻohana ʻia ka waikawa Methacrylic a me nā methacrylate esters e hoʻomākaukau i kahi ākea o nā polymers [→ Polyacrylamides a me Poly(Acrylic Acids), → Polymethacrylates]. ʻO Poly(methyl methacrylate) ka polymer mua ma kēia māhele, a hāʻawi ia i nā plastics wai-maʻemaʻe, paʻakikī i hoʻohana ʻia ma ke ʻano pepa i ka glazing, nā hōʻailona, nā hōʻikeʻike, a me nā panela kukui. | |

Palekana
I ka wā e lawelawe ai i kēia huahana, e ʻoluʻolu e mālama i nā ʻōlelo aʻoaʻo a me ka ʻike i hāʻawi ʻia ma ka pepa ʻikepili palekana a e mālama i nā hana palekana a me nā hana hoʻomaʻemaʻe wahi hana kūpono no ka lawelawe ʻana i nā kemika.

Hoʻokumu ʻia ka ʻikepili i loko o kēia puke pai ma ko mākou ʻike a me ka ʻike o kēia manawa. Ma muli o nā kumu he nui e hoʻopilikia ai i ka hana ʻana a me ka hoʻohana ʻana i kā mākou huahana, ʻaʻole kēia mau ʻikepili e hoʻokuʻu i nā mea hana mai ka hana ʻana i kā lākou mau noiʻi a me nā hoʻāʻo ponoʻī; ʻaʻole hoʻi kēia mau ʻikepili e hōʻoia i kekahi hōʻoia o kekahi mau waiwai, a me ke kūpono o ka huahana no kahi kumu kikoʻī. Hiki ke loli nā wehewehe ʻana, nā kiʻi, nā kiʻi paʻi, nā ʻikepili, nā ʻāpana, nā kaumaha, a me nā mea ʻē aʻe i hāʻawi ʻia ma ʻaneʻi me ka ʻole o ka ʻike mua a ʻaʻole ia he ʻaelike maikaʻi o ka huahana. ʻO ka maikaʻi o ka huahana i ʻaelike ʻia ma muli wale nō o nā ʻōlelo i hana ʻia ma ka kikoʻī huahana. ʻO ke kuleana o ka mea loaʻa i kā mākou huahana e hōʻoia i ka mālama ʻia ʻana o nā kuleana ponoʻī a me nā kānāwai a me nā kānāwai e kū nei.
