MMA (Methyl Methacrylate): Monomer iiyandika kapati yama polymers aabeleka obotu
Zibeela Zipati Zyakubelesya
Mumakwebo aamapulasitiki, PMMA ilabelesyegwa kapati mukupanga mapepa aasalala, ma tube, azibelesyo zyakubelesya mumeso akaambo kabubotu bwayo bwakulanga. Chilasalala loko, chitondeezya mumuni muniini, akukazya mumuni uuzwa mumulengalenga, kupa kuti chibelesyegwe muzintu zilimbuli zitondezyo, ziimvwi zyakutondezya, malambe aamusyule aamyootokala, antoomwe azivwunisyo zyandeke. Kuyungizya waawo, PMMA ilakonzya kukazyigwa amakemikalu akuyuma kwaminchina zipa kuti ibe kabotu kuzibelesyo zyakupanga chakulya azibelesyo zyabusilisi.
Muchibaka chakuvwumba azyakunamatika, MMA ilabelesyegwa kupanga zintu zyiingi zibeleka obotu. Aaya ma resini atondezya kujatana kubotu, kukazyigwa achiindi, akukazyigwa kwamakemikalu, zipa kuti abelesyegwe kapati mukuvwumba zintu zyakuyaka, kuvwumba myootokala, akuvwumbilila zibelesyo zyamagesi. Zinamatizyo zya MMA, zyizibinkene akufwambaana kuyuma akukonzya kujatana kwazyo, zilabelesyegwa kapati mukunamatizya zisamu, nsimbi, azintu zyapulasitiki.
Mumulimo wazibelesyo zyakulanga, MMA nchintu chipati chibelesyegwa mukupanga ntambo zyakulanga ama lensi. Bubotu bwayo bwakulanga akukwabilila zuba bupa kuti ibe chintu chibotu kubelesyegwa mumumuni, kubikkilizya azibelesyo zyakukambawukila zya fiber optic alimwi ama lensi aabeleka obotu. Kuyungizya waawo, MMA ilabelesyegwa mukupanga zibelesyo zyakusololela mumuni azibelesyo zyakumvwa.
Mumakwebo aakupanga zintu, MMA ilabelesyegwa kupanga zintu zipangidwe a methyl methacrylate resin. Eezyi zintu zipangidwe antoomwe zilaanguzu zipati, tazijisi bunji bwazintu, alimwi tazikonzyi kubola, calo cipa kuti zibelesyegwe kapati muzibelesyo zyamumulengalenga, mumyootokala, alimwi amuzibelesyo zyazisobano. Mbuli chitondeezyo, zintu zipangwa a MMA zibelesegwa mumababa aandeke, mumibili yamyootokala, amumasobano aagolufu.

Kakuli kuyaambele kwabusongo bwakupanga zintu, nzila zyakubelesya MMA zilazumanana kuyaambele. Mbuli chitondeezyo, mumulimo wakusimba 3D, MMA ilabelesyegwa kupanga zintu zyakusimba 3D zibeleka obotu. Mumulimo wabusilisi bwazilenge, MMA ilabelesyegwa kupanga zibelesyo zyabusilisi zikonzya kubola alimwi azibelesyo zyakupanga zizo. Kuchita zintu zyiingi akubeleka kabotu kwa MMA kupa kuti ibe chintu chiyandikana loko mumakwebo aamazubaano, kupa lugwasyo lupati mukusumpula zibeela zyiingi.
