I-Phthalic Anhydride (PA) I-CAS No.: 85-44-9

Inkcazelo emfutshane:

Product Overview

I-Phthalic Anhydride (PA) yimathiriyeli ekrwada yekhemikhali ebalulekileyo ephilayo, eveliswa ikakhulu yi-oxidation ye-ortho-xylene okanye i-naphthalene. Kubonakala ngathi ikristale emhlophe eqinileyo kunye nevumba elincinci elicaphukisayo. I-PA isetyenziswa kakhulu kwimveliso yeeplastiki, iintlaka zepolyester ezingaxutywanga, iiresin zealkyd, iidayi, kunye neepigments, nto leyo eyenza ukuba ibe yinto ephakathi kwishishini lemichiza.

Ezona mpawu

• Ukusebenza okuphezulu:I-PA iqulethe amaqela e-anhydride, asabela ngokukhawuleza kunye neealkoholi, ii-amines, kunye nezinye iikhompawundi ukwenza i-esters okanye i-amides.
• Ukunyibilika kakuhle:Inyibilika emanzini ashushu, utywala, ethers, kunye nezinye izinyibilikisi eziphilayo.
• Uzinzo:Izinzile phantsi kweemeko ezomileyo kodwa i-hydrolyzes kancinane ukuya kwi-phthalic acid kubukho bamanzi.
• Ukuguquguquka:Isetyenziswa ekudityanisweni koluhlu olubanzi lweemveliso zeekhemikhali, nto leyo eyenza ukuba ibe nezinto ezininzi.

Usetyenziso

1. IiPlastiki:Isetyenziselwa ukuvelisa i-phthalate esters (umzekelo, i-DOP, i-DBP), esetyenziswa ngokubanzi kwiimveliso ze-PVC ukuphucula ukuguquguquka kunye nokuqhubekeka.
2. Iireyithi zePolyester ezingafakwanga:Isetyenziswa ekwenzeni i-fiberglass, i-coatings, kunye ne-adhesives, enikezela ngeempawu ezibalaseleyo zoomatshini kunye nokumelana nemichiza.
3. Alkyd Resins:Isetyenziswe kwipeyinti, iingubo, kunye neevanishi, ukubonelela ngokunamathela kakuhle kunye negloss.
4. Idayi kunye neePigments:Isebenza njengendawo ephakathi kwi-synthesis yedayi ye-anthraquinone kunye ne-pigments.
5. Ezinye izicelo:Isetyenziswa kwimveliso yamayeza aphakathi, amayeza okubulala izitshabalalisi, neziqholo.

Ukupakishwa kunye noGcino

• Ukupakishwa:Ifumaneka nge 25 kg/bag, 500 kg/bag, okanye ton bag. Iinketho zokupakisha eziqhelekileyo ziyafumaneka xa uceliwe.
• Ugcino:Gcina kwindawo epholileyo, eyomileyo, nengena umoya. Kuphephe ukudibana nokufuma. Ubushushu bokugcina obucetyiswayo: 15-25℃.

Ukhuseleko nokuqwalaselwa kokusiNgqongileyo

• Ukucaphuka:I-PA iyacaphukisa ulusu, amehlo, kunye nenkqubo yokuphefumla. Izixhobo ezifanelekileyo zokukhusela (umzekelo, iiglavu, izibuko, iziphefumli) kufuneka zinxitywe ngexesha lokuphatha.
• Ukutsha:Iyatsha kodwa ayivuthi kakhulu. Zigcine kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu.
• Impembelelo yokusingqongileyo:Lahla izinto ezilahlwayo ngokuhambelana nemigaqo yendalo esingqongileyo ukuthintela ungcoliseko.
