I loko o kametila methacrylateke kaʻina hana, ʻo ka nānā pono ʻana i ka maʻemaʻe monomer a me ka reactivity he mea nui ia no ka polymerization kūlike. ʻO nā ʻano polymerization nui i ka hana acrylic e pono ai ka kaohi paʻa o ka radical initiator dosing a me ka wehe ʻana i ka wela.

ʻIkepili Kaʻina Hana ʻOihana Koʻikoʻi
Hoʻohana ke kaʻina hana hana methyl methacrylate i ka methylation catalytic a i ʻole ka esterification oxidative pololei e hana i ka monomer MMA. Hoʻohana pinepine ka methylation catalytic i nā mea hoʻouluulu Mg/Ga oxide i hui pū ʻia, e hoʻokō ana i ke koho kiʻekiʻe a me ka hua, me ka hōʻemi ʻana i ka hoʻokumu ʻana o ka huahana byproduct. ʻO ka methylation pololei, i hoʻohālikelike ʻia ma Aspen Plus, hiki ke hana hou ʻia me ka maikaʻi, e ʻae ana i ka maʻemaʻe MMA a hiki i ka 99.9% me ka hoʻemi ʻana i ka hoʻohana ikehu.
Uhi ka kiʻikuhi kahe hana methyl methacrylate i ka hoʻokomo ʻana o nā mea maka, nā ʻanuʻu hoʻomaʻemaʻe MMA, a me nā pae hoʻopaʻa. A laila hāʻawi ʻia ka MMA paʻa i nā ʻāpana polymerization nui ma o nā paipu pani, e hoʻemi ana i ka haumia a me ka pohō.
ʻO ke kaʻina hana polymerization bulk methyl methacrylate e pili ana i nā mea hoʻomaka radical, ka hoʻokele wela pololei, a me ka hoʻolaha kaulahao polymer hoʻomau. Hōʻoia ka mana wela o ka reactor i ka hoʻololi like a pale i nā hopena exothermic holo.
