Ko te hexahydrophthalic anhydride me te diphenyl maleate (i hangaia mai i te MA Maleic anhydride) he kaiwhakaahua ā-waho mahi-teitei. Ahumahi Kai. Ko te waikawa fumaric (mai i te MA Maleic anhydride...Pānuihia atu -
Me pēhea te whakamahinga o te maleic anhydride i roto i ngā patupatu me ngā paninga?
I roto i ngā paninga, ka mahi te anhydride maleic hei wāhanga hanga kiriata mō ngā paninga kapia wai-tū, hinu-tū, me te kapia hangai (hei tauira, te alkyd, te polyester, te rosin maleic anhydride-modified, me ngā kapia hinu-maleic-waikawa tung). Ngā patupatu. Ko te malathion (i hangaia mai i te anhydride maleic me te P205) he iti te paitini...Pānuihia atu -
He aha te whakamahinga o te maleic anhydride i roto i ngā kapia hangai?
Ngā Resin Hanga Ka tauhohe te maleic anhydride ki ngā polyol (ā, muri iho ka honoa ki te styrene) hei hanga i ngā resin polyester kāore i te mākū (UPR), he resin thermosetting. Kua wehea te UPR ki ngā kirihou whakakaha-muka (FRP, e mōhiotia whānuitia ana ko te kirihou whakakaha-muka karāhe) me ngā kirihou kāore i te whakakaha. FRP i...Pānuihia atu -
He aha ngā matū ka puta mai i te maleic anhydride?
He whānui rawa ngā whakamahinga o te anhydride maleic, e whakamahia ana i roto i te hanga kapia polyester kāore i te mākū (UPR) (ngā mea kua whakakahangia, ngā mea kāore i te whakakahangia), ngā paninga, ngā peita, ngā waituhi, ngā kirihou hangarau, ngā rongoā, ngā patupatu pepeke, te hanga pepa, ngā āwhina kakahu, ngā tāpiringa kai, ngā tāpiringa whāngai...Pānuihia atu -
