Maleic Anhydride: Nchintu chipati chakubelesya misamu iikola iisololela kuyaambele muzibeela zyiingi
Zibeela Zipati Zyakubelesya
Mumakwebo aamisamu, maleic anhydride nchintu chipati loko mukupanga ma unsaturated polyester resins (UPR). Aaya ma resini alijisi bube bubotu bwakubelesya minchina, kukazyigwa amakemikalu, akukazya kuchincha kwamvwula mpawo abelesegwa kapati mukupanga mapulasitiki aajisi nsinga zyagilazi (GFRP), mbuli mato, zibeela zyamyootokala, antoomwe amabbala aamuwo. Kuyungizya waawo, maleic anhydride ilakonzya kubelesegwa kupanga alkyd resins, eezyo zijisi kumweka kubotu akuyuma alimwi zibelesyegwa kapati mumakkampani aazisani aama inki.
Mumakwebo aapulasitiki, maleic anhydride ilabelesyegwa kupanga mapulasitiki aasandulwa a maleic anhydride. Kwiinda mukupanga ma monomers aasiyene, maleic anhydride ilakonzya kusumpula bube bwamapulasitiki, mbuli kuyungizya nguzu zyakukazya kupya akuyuma kwaminchina. Mbuli chitondeezyo, maleic anhydride grafted polystyrene, copolymerized a styrene, ilijisi nguzu zyakukazya kupya alubo ilakonzya kubelesegwa kapati mumakkampani aapanga magesi amumyootokala.
Mumakwebo aa raba, maleic anhydride ilabelesyegwa kupanga zintu zyakuyungizya raba. Ilakonzya kuswaangana a raba kuti ipange zintu zijatikizyidwe, ikuyungizya kukazyigwa kwakupya akukazya kusama kwa raba. Maleic anhydride alimwi ilabelesyegwa kupanga misamu iikola ya raba alimwi amisamu iilwana kuchembaala, ikuyungizya buumi bwama raba.
Mumakkampani aapanga tununkilizyo amisamu, maleic anhydride ibelesyegwa mbuli chintu chili akati-akati mukupanga zintu zipona. ilakonzya kubelesegwa kupanga tununkilizyo tunji, mbuli diethyl maleate, eeyo iibelesyegwa kapati mumafuta aanunkilila. Kuyungizya waawo, maleic anhydride ilakonzya kubelesegwa kupanga misamu imwi, mbuli misamu iizwa ku maleic anhydride, mukupanga misamu iijaya tuzunda alimwi amisamu yamoyo.
Mukusalazya maanzi, maleic anhydride ilabelesyegwa kupanga misamu yakusalazya maanzi. ilakonzya kuswaangana a calcium antoomwe a magnesium ions mumaanzi kuti ipange zintu zitakonzyi kunywika, aboobo eezi zipa kuti maanzi aleke kuyuma. Maleic anhydride ilakonzya kubelesegwa kupanga zintu zilesyela kubola akukwabilila kubola akubola mumaanzi.
Nikuba kuti ilakonzya kubelesegwa munzila zyiingi, maleic anhydride ilijisi asidi mpawo ilakonzya kubola, mpawo kubelesya akubamba kwayo kuyandika nzila zyakukwabilila. Maleic anhydride ilafwambaana kuyoya busi mumasena aatontola, aboobo yeelede kuyobolwa muchikombe chijalilidwe. Kuyungizya waawo, misamu ya maleic anhydride ilakonzya kubola, mpawo zibelesyo zyakulikwabilila zyeelede kuzwalwa muchiindi chakubelesya kuchitila kuti kutabi kuguma chikumba ameso. Mukupanga zintu mumafakitali, kubelesya maleic anhydride kanjikanji kuchitwa mumasena aajalidwe kuchitila kuti kutabi ntenda kubusena.

Mubufwaafwi
Muchi chifwiifwi, maleic anhydride, mbuli musamu uuyandika kapati, ulaa mulimo mupati mumakwebo miingi. Tachikonzyi buyo kusumpula bubotu bwazintu pesi alimwi chigwasyilizya kuyaambele kwamakwebo aamazubaano. Kakuli kuyaambele kwabusongo, nzila zyakubelesya maleic anhydride ziyooba zipati.
