Incazelo emfushane:
Igama Lomkhiqizo: i-anhydride ye-Maleic
I-CAS:108-31-6
MF:C4H2O3
I-MW:98.06
ISAKHIWO:
I-Maleic Anhydride (MAN) iyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali i-C4H203. Iyi-anhydride ye-asidi ye-maleic acid futhi esimweni sayo esimsulwa iyisithako esingenambala noma esimhlophe esinephunga elibi. I-Maleic anhydride iyi-molecule emangalisayo ngoba inezinhlobo ezimbili zokusebenza kwamakhemikhali okwenza ibe usizo ngokukhethekile ekuhlanganisweni kwamakhemikhali nasekusetshenzisweni kwawo.
I-Maleic Anhydride iyikhemikhali esebenza ngezindlela eziningi esetshenziswa emikhakheni eminingana yemboni yamakhemikhali. Ukusetshenziswa kwayo okukhulu njengokudla okunempilo ekukhiqizweni kwama-resin e-polyester angagcwalisiwe (UPR).
Lawa ma-resin asetshenziswa kokubili ekusetshenzisweni okuqiniswe ngengilazi kanye nasekusetshenzisweni okungaqinisiwe. Ukusetshenziswa kwe-UPR ekugcineni kuhlanganisa izinhlobo eziningi zezicelo ezimbonini zokwakha, zasolwandle kanye nezimoto.

Ukusetshenziswa
I-Maleic Anhydride iyinhlanganisela ye-heterocyclic esetshenziswa ekwenziweni kwama-resin e-polyester angagcwali. Inezinhlobo eziningi zezinye izinhlelo zokusebenza; isetshenziswa kuma-tensides okwenziwa, ama-insecticide, ama-herbicides kanye nama-fungicides.
I-anhydride yama-Maleic isetshenziswa ekwenziweni kwe-Diels-Alder (njenge-dienophile), ekukhiqizweni kwama-resin ohlobo lwe-alkyd, izinto ezishintsha umbala, imithi, amakhemikhali ezolimo (i-maleic hydrazide, i-malathion), ekuphenduleni kwe-copolymerization.
Ukupakisha Nokuthumela
25KG/Isikhwama noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
