Na Waiwai Kemika:
ʻO ka Methyl 2-methyl-2-propenoate ka mea ʻala ʻala. Ma kekahi hōʻike ʻē aʻe, ua hōʻike ʻia kēia pūhui i kahi ʻala ʻoi a me nā hua. He wai waihoʻoluʻu ʻole me ka ʻala hua ʻala. He kiʻekiʻe kona puʻe mahu (4 kPa ma 20°C), haʻahaʻa haʻahaʻa wai hoʻoheheʻe (15.8 g/lita), a me kahi log octanol/wai ʻāpana ʻāpana haʻahaʻa (Kow = 1.38). ʻO ka methyl methacrylate maʻamau he 99.9% maʻemaʻe a loaʻa i nā mea hoʻopaneʻe liʻiliʻi e hoʻopaneʻe i ka polymerization.
Noi:
1.ʻO ka Methyl methacrylate kahi mea hoʻoheheʻe synthetic i hoʻohana nui ʻia i ka hana ʻana i ka pepa acrylic cast, emulsions acrylic, a me ka hoʻoheheʻe ʻana a me nā resins extrusion.
2.I ka hana ʻana i nā resins methacrylate a me nā plastics. Hoʻololi ʻia ka Methyl methacrylate i nā methacrylate kiʻekiʻe e like me ka n-butyl methacrylate a i ʻole 2-ethylhexylmetacrylate.
3.Hoʻohana ʻia ka methyl methacrylate monomer i ka hana ʻana i nā polymers methylmethacrylate a me nā copolymers, nā polymers a me nā copolymers i hoʻohana ʻia i ka wai, ka mea hoʻoheheʻe, a me nā mea i hoʻoheheʻe ʻole ʻia, nā mea hoʻopili, nā mea hoʻopaʻa, nā ʻili a me nā ʻili pepa, nā ʻīnika, nā polū papahele, nā lole lole, nā prostheses niho, nā sima iwi ʻokiʻoki, a me nā pale radiation acrylic alakaʻi a i ka hoʻomākaukau ʻana i nā manamana lima synthetic a me nā hoʻokomo kāmaʻa orthotic. Hoʻohana pū ʻia ka Methyl methacrylate i mea hoʻomaka e hana i nā esters ʻē aʻe o ka methacrylic acid.
4.Hoʻohana ʻia nā Granules no ka injection a me ka extrusion blow molding no ko lākou ʻike maikaʻi maikaʻi loa, ka wā a me ke kūʻē ʻana i ka ʻōpala i hoʻohana ʻia i nā kukui, nā lako keʻena a me nā mea uila (hōʻike kelepona kelepona a me nā mea hi-fi), hale a me ke kūkulu ʻana (glazing a me nā puka aniani), ka hoʻolālā o kēia wā. (nā lako, nā mea nani a me nā papa ʻaina), nā kaʻa a me ka lawe ʻana (nā kukui a me nā panela mea kani), ke olakino a me ka palekana (nā ipu a me nā paipu hoʻāʻo) a me nā mea pono hale (nā puka umu microwave a me ka mixer. nā kīʻaha).
5.Hoʻololi i ka hopena no ka polyvinyl chloride paʻa pono.
