Maleic Anhydride: He Rauemi Mata Matū Waro Matua e Ārahi ana i te Whanaketanga puta noa i ngā Rāngai Maha
Ngā Āpure Tono Matua
I roto i te umanga matū, ko te anhydride maleic te rauemi mata matua mō te hanga kapia polyester kore-mākū (UPR). He tino pai ngā āhuatanga miihini o ēnei kapia, he ātete matū, he ātete huarere hoki, ā, he whānuitia te whakamahinga i roto i te hanga kirihou whakakaha muka karāhe (GFRP), pērā i ngā poti, ngā wāhanga motuka, me ngā mata o te tāhū hau. Hei tāpiri, ka taea te whakamahi i te anhydride maleic hei hanga kapia alkyd, he pai te kanapa me te pakari, ā, he whānuitia te whakamahinga i roto i ngā umanga paninga me ngā waituhi.
I roto i te umanga kirihou, ka whakamahia te maleic anhydride hei hanga i ngā kirihou kua whakarerekētia ki te maleic anhydride. Mā te whakakotahi i ngā monomer rerekē, ka taea e te maleic anhydride te whakapai ake i ngā āhuatanga o ngā kirihou, pērā i te whakanui ake i te ātete wera me te kaha miihini. Hei tauira, ko te polystyrene kua honoa ki te maleic anhydride, kua whakakotahitia ki te styrene, he ātete wera me ngā āhuatanga miihini pai rawa atu, ā, he whānuitia te whakamahinga i roto i ngā umanga hikohiko me te motuka.
I roto i te umanga rapa, ka whakamahia te anhydride maleic hei hanga i ngā tāpiri rapa. Ka taea e ia te tauhohe ki te rapa hei hanga i ngā hanganga honohono, hei whakarei ake i te ātete wera me te ātete kakahu o te rapa. Ka whakamahia hoki te anhydride maleic hei hanga i ngā kaihoko whakamomona rapa me ngā kaihoko ārai-pakeke, hei whakaroa i te roa o te ora o ngā hua rapa.
I roto i ngā ahumahi kakara me te rongoā, ka whakamahia te maleic anhydride hei takawaenga i roto i te hanga rauropi. Ka taea te whakamahi hei hanga i ngā momo matū kakara, pērā i te diethyl maleate, e whakamahia whānuitia ana i roto i ngā hinu kakara me ngā mea whakapaipai. Hei tāpiri, ka taea te whakamahi i te maleic anhydride hei hanga i ētahi takawaenga rongoā, pērā i ngā hua o te maleic anhydride, hei hanga i ngā paturopi me ngā rongoā ngakau.
I roto i te maimoatanga wai, ka whakamahia te anhydride maleic hei whakaputa i ngā kaihoko maimoatanga wai. Ka taea e ia te tauhohe ki ngā katote konupūmā me te konupora i roto i te wai hei hanga i ngā matū kore e rewa, ā, ka whakaiti i te pakeketanga o te wai. Ka taea hoki te whakamahi i te anhydride maleic hei whakaputa i ngā aukati waikura me ngā aukati unahi hei ārai i te waikura me te unahi i roto i ngā pūnaha wai.
Ahakoa te whānuitanga o ngā whakamahinga, he waikawa, he waikura hoki te maleic anhydride, ā, me tino tupato te whakamahinga me te rokiroki. Ka mimiti ngāwari te maleic anhydride i te makuku i roto i ngā taiao haukū, nō reira me penapena ki roto i tētahi ipu hiri. Hei tāpiri, he waikura te maleic anhydride, ā, me mau ngā taputapu tiaki tika i te wā e whakamahia ana kia kore ai e pā ki te kiri me ngā kanohi. I roto i te whakaputanga ahumahi, ko te whakamahinga o te maleic anhydride ka puta i roto i ngā pūnaha kati hei whakaiti i te pānga ki te taiao.

Hei whakarāpopototanga
Hei whakarāpopototanga, ko te maleic anhydride, he rauemi mata matū waro nui, he mahi nui tana i roto i ngā ahumahi maha. Ehara i te mea ka whakarei ake i te mahi me te kounga o ngā hua engari ka tautoko hoki i te whanaketanga o ngā ahumahi hou. Mā te haere tonu o ngā whanaketanga hangarau, ka whānui ake ngā tūmanakohanga tono mō te maleic anhydride.
