Anhydride Maleic
Tirohanga Whānui o te Hua
Ko te anhydride maleic (CAS No.: 108-31-6) he anhydride waro kore-mākū matua me te tauira matū o C₄H₂TE₃He rite ki ngā maramara tioata mā, kōwhai mārama rānei, he kakara kaha, he kaha te tauhohenga, ā, he tino hototahi ki ngā momo monomer me ngā matū. Hei rauemi mata matū waro maha-whakamahinga, he whānuitia te whakamahinga i roto i ngā polymer, ngā paninga, ngā rongoā, te ahuwhenua, me ngā ahumahi hinu me te hau, e whakarato ana i te mahi pumau me te kounga pono mō te whakaputa ahumahi.;
Ngā tono me ngā whakamahinga
Nā te maha o ngā whakamahinga o te Maleic Anhydride:
Ngā Resin Polyester Kore-Makuku (UPR)
Te Whakamahinga Matua: Neke atu i te 50% o te hanga MA o te ao e whakamahia ana i roto i ngā UPR.
Ngā Hua Whakamahinga-Mutu: Ngā kirihou kua whakakahangia ki te muka karāhe, ngā tāke, ngā paipa, ngā wāhanga motuka, ngā takere poti, me ngā panera hangahanga.
Ngā Copolymer
Ngā Tāpiri Hinu Whakahinuhinu: Whakamahia hei wāhanga o ngā copolymers e mahi ana hei whakapai ake i te taupū matotoru me te whakarewa.
Paninga Mata: He rauemi mata mō ngā kapia alkyd e whakamahia ana i roto i ngā peita me ngā paninga ahumahi kounga teitei.
Ngā Matū Ahuwhenua
Waenga: Whakamahia hei hanga i ngā patu pepeke, ngā patu taru (hei tauira, Malathion), me ngā kaiwhakahaere tipu tipu.
Ngā Tāpiringa Kai
Waikawa Fumaric me te Malic: Ko te Maleic Anhydride te matūriki o ēnei waikawa kore-paitini, e whakamahia ana hei waikawa i roto i ngā inu me ngā hua kai.
Ētahi atu Taupānga
Te Rahi Pepa: Whakamahia hei hanga i te alkyl ketene dimer (AKD), he mea rahi noa mō te pepa.
Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): He ara nui te Cis-Butenedioic Anhydride mō te whakaputa i ēnei whakarewa whai hua.
Anhydride Succinic: Ka taea te huri hei anhydride succinic mō ngā momo hanga matū.
