Fa'amatalaga Pupuu:
Igoa o le Oloa: Maleic anhydride
CAS:108-31-6
MF:C4H2O3
MW:98.06
FA'ATULAGA:
O le Maleic Anhydride (MAN) o se vailaʻau faʻaola e iai le fua faʻatatau o le vailaʻau C4H203. O le acid anhydride lea o le maleic acid ma i lona tulaga mama e leai se lanu poʻo se mea maʻaʻa paʻepaʻe ma se manogi oona. O le Maleic anhydride o se molecule mataʻina moni lava ona e lua ituaiga o galuega faʻa-kemikolo e avea ai ma mea e aoga tele i le gaosiga ma faʻaoga faʻa-kemikolo.
O le Maleic Anhydride o se vaila'au fa'afefiloi e tele ona galuega ma e fa'aoga i le tele o vaega o pisinisi vaila'au. O lona fa'aoga autu o le avea ma mea e fafaga ai i le gaosiga o unsaturated polyester resins (UPR).
O nei resins e faʻaaogaina i faʻaoga e faʻamalosia i tioata ma faʻaoga e leʻi faʻamalosia. O faʻaoga mulimuli a le UPR e aofia ai le tele o faʻaoga i galuega faufale, gataifale ma pisinisi taʻavale.

Fa'aaogāga
O le Maleic Anhydride o se vailaʻau heterocyclic e faʻaaogaina i le gaosiga o unsaturated polyester resins. E tele isi ona faʻaoga; e faʻaaogaina i vailaʻau faʻapitoa, vailaʻau faʻamaʻi iniseti, vailaʻau faʻamaʻi vao ma vailaʻau fungicides.
E fa'aaogaina le maleic anhydride i le Diels-Alder syntheses (e fai ma dienophile), gaosiga o alkyd-type resins, dye intermediates, pharmaceuticals, fa'ato'aga vaila'au (maleic hydrazide, malathion), i tali o le copolymerization.
Afifiina ma le Felauaiga
25KG/Taga po'o mana'oga o tagata fa'atau.
E patino i oloa masani ma e mafai ona tilivaina i le vasa ma le ea
Tausia ma teuina
Umi e teu ai: 24 masina mai le aso na gaosia ai i totonu o le afifiina muamua e leʻi tatalaina teuina i se nofoaga malūlū ma mago, ʻaloʻese mai le la saʻo, vai.
Faleteuoloa e fa'amamago i le ea, fa'amago i le vevela maualalo, Vavae'ese mai mea e fa'aola ai le ea, 'asi.
