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.

Ngā Painga o te Hua

2 5-Furandine Teitei o te Parakore: Mā te Parakore ≥ 99.5% ka pumau te mahi tauhohenga, ā, ka whakaitihia ngā hua taha i roto i te whakaputanga o raro.

Kounga Pūmau: Mā te whakahaere kounga tino pakari puta noa i te tukanga whakaputa (mai i te kōwhiringa rauemi mata ki te tirotiro hua kua oti) ka whakarite kia ōrite te mahi i ia puranga.

Te Tauhohenga Pai Rawa: Mā te tauhohenga teitei me ngā diol, ngā amine, me ngā monomer ka taea te hanga pai o ngā hua o muri mai.

Te Hanganga Ā-Taiao: E whakamahi ana i ngā hangarau whakaputa matatau me te iti o te whakapaunga pūngao me te iti o te para, me te tutuki i ngā paerewa taiao o te ao.

Te Tākai me te Rokiroki i te Waikawa Anhydride Maleic

Mōkihi: 25kg te taumaha kupenga mō ia pēke pepa kraft (me te uhi polyethylene o roto) 1000kg rānei ngā pēke nunui, e tika ana mō te kawe moana me te kawe whenua.

Rokiroki: Rokirokihia ki roto i tētahi whare putunga hauhautanga, maroke, he pai te hauhautanga, kia matara atu i ngā pūtake wera, i ngā mura tuwhera, me ngā waikura kaha. Āraia te mimiti makuku (tērā pea ka huri hei waikawa maleic) me te rā tika. Te roa o te oranga: 12 marama i raro i ngā tikanga rokiroki tika.

Te Haumaru me te Whakahaere i te Cis-Butenedioic Anhydride

Tiakitanga Whaiaro: Mauria he karapu ātete-matū, he mōhiti kanohi, me te kopare puehu i te wā e pā ana. Āta karohia te pa atu ki te kiri, ki ngā kanohi, me te ara manawa.

Āwhina Tuatahi: Mēnā ka pā ki te kiri, horoia tonutia ki te nui o te wai mō te 15 meneti; mēnā ka pā ki ngā kanohi, horoia ki te wai ka rapu awhina hauora. Mēnā ka hongia, neke atu ki te hau hou ka toro atu ki te tākuta.

Te Whakahaere i te Ringihia: Mimia ngā mea i ringihia ki ngā mea mimiti korekore (hei tauira, te onepu, te vermiculite), kohia ki roto i ngā ipu hiri, ka maka atu kia rite ki ngā ture taiao ā-rohe. Kaua e maka ki roto i ngā puna wai, ki te oneone rānei.
