I-Pyromellitic Dianhydride (PMDA)

I-Pyromellitic Dianhydride (PMDA) iyi-dianhydride enamakha enephunga elimnandi eyaziwa kabanzi njenge-monomer eyinhloko ekukhiqizeni ama-polyimide asebenza kahle kakhulu. Le nhlanganisela ye-organic eguquguqukayo ihlanganisa amaqembu amabili e-anhydride axhunywe kwindandatho ye-benzene, ehlinzeka ngokuzinza okungavamile kokushisa, amandla okusebenza, kanye nokumelana namakhemikhali.

Ukupakisha kanye Nesitoreji

• 25kgs Ukupakishwa kwesigubhu sephepha, okufakwe izikhwama ze-PE, izikhwama zephepha le-aluminium yangaphandle izendlalelo ezimbili zamaphakheji avaliwe.

• Gcina isitsha sivalwe ngokuqinile endaweni eyomile futhi enomoya omuhle.

Izici Eziyinhloko ze-Pyromellitic Dianhydride (PMDA)

• I-Solubility: I-Soluble kuma-solvents e-polar njenge-dimethyl sulfoxide (DMSO), i-dimethylformamide (DMF), ne-acetone; ayincibiliki ku-ether, i-chloroform, ne-benzene

• I-Hygroscopic Nature: Imunca ngokushesha umswakama emoyeni oswakeme, i-hydrolyzing ibe yi-pyromellitic acid.

• I-reactivity: Isebenza kakhulu ekuncibilikeni, ikwenze ilungele i-polymerization kanye nezinqubo zokuphulukisa

• Ukuzinza Kwe-Thermal: Kunika amandla izinto ezisetshenziswayo ezinamazinga okushisa engilazi aphezulu (Tg kufika ku-300°C noma ngaphezulu kumasistimu alashiwe)

Izicelo Eziyinhloko ze-Pyromellitic Dianhydride (PMDA)

I-Pyromellitic Dianhydride (PMDA) ibalulekile ekukhiqizeni izinto ezithuthukisiwe ngenxa yekhono layo lokunikeza ukumelana nokushisa okuphakeme, ukuncipha komlilo, nokuqina:

Ama-Polyimide Resins namafilimu: 

I-Core monomer yokuhlanganisa ama-polyimides asetshenziswa kumasekethe aphrintiwe aguquguqukayo, izingxenye ze-aerospace, amafilimu okufakwa kwe-insulation, nama-electronics anezinga lokushisa eliphezulu.

I-Epoxy Resin Curing Agent: 

Isebenza njenge-ejenti exhumanisayo nelaphayo yezinhlelo ze-epoxy, ithuthukisa amandla emishini, ukumelana namakhemikhali, nokusebenza okushisayo kokunamathelayo, okokuhlanganisa, izinhlanganisela, kanye ne-encapsulation kagesi.

Ama-Coatings Nezinamathiselo Ezisebenza Kakhulu: 

Ithuthukisa ukuqina kwe-oxidative kanye nezakhiwo zemishini emigqeni yokuvikela yezinhlelo zokusebenza zezimboni nezezimoto.

Thermoplastics kanye Plasticizers: 

Isetshenziswa ekukhiqizeni ama-polyester, ama-polyethers, ama-polycarbonates, namapulasitiki wobunjiniyela ane-flame retadancy enhle kakhulu.

Okunye Ukusetshenziswa: 

I-Chain extender ku-polyethylene terephthalate (PET), i-ejenti yokuhlanganisa kuma-powders, kanye nokuqiniswa kuma-resin akhethekile.

Lezi zinhlelo zokusebenza zenza i-PMDA ibaluleke kakhulu ezimbonini ezifana ne-aerospace, electronics, automotive, kanye ne-microelectronics, lapho izinto ezisetshenziswayo kumele zimelane namazinga okushisa adlulele kanye nezindawo ezinokhahlo.

Imibuzo Evame Ukubuzwa (FAQs)

Umbuzo: Yiziphi izinto ezisetshenziswa kakhulu ze-PMDA?

A: Isetshenziswa kakhulu kumafilimu e-polyimide ku-electronics kanye ne-aerospace, ukuphulukiswa kwe-epoxy kokunamathela okuphezulu nokusebenza kahle, nanjenge-agent exhumanisa ku-thermoplastics.

Umbuzo: Ingabe i-PMDA i-hygroscopic?

A: Yebo, i-PMDA imunca ngokushesha umswakama ovela emoyeni bese i-hydrolyzes ibe yi-pyromellitic acid. Gcina njalo ezitsheni ezivaliwe ezimweni ezomile.

Q: Liyini iphuzu lokuncibilika kwe-PMDA?

A: Indawo yokuncibilika isukela ku-284-288°C, okunikela ekuzinzeni kwayo okushisayo kokuphezulu ezinhlelweni zokusebenza.

Umbuzo: Kufanele igcinwe kanjani i-PMDA?

IMPENDULO: Gcina endaweni epholile, eyomile ezitsheni ezivalwe ngci, ezivikelwe kumswakama kanye nezinto ezingahambelani.

Q: Yiziphi izincibilikisi ezincibilikisa i-PMDA?

A: Iyancibilika ku-DMSO, i-DMF, ne-acetone kodwa ayincibiliki ku-ether, i-chloroform, ne-benzene.

Q: Ingabe i-PMDA ilungele ukwelapha i-epoxy resin?

A: Yebo, isebenza njenge-ejenti yokwelapha ephumelelayo, ngokuvamile edinga ukuchithwa kwangaphambili kwe-acetone noma ukuhlakazeka okuhle ngenxa yephoyinti layo eliphezulu lokuncibilika.

Q: Yiziphi izimboni ezivame ukusebenzisa i-PMDA?

A: I-Aerospace (yamafilimu amelana nokushisa), izinto zikagesi (izinto zokuvikela ukushisa neziyindilinga), ezezimoto (izingxenye ezishisa kakhulu), kanye nemikhakha yezingubo zokunamathela/zokunamathela.
