I-Phthalic Anhydride (PA) Inombolo ye-CAS: 85-44-9

Incazelo emfushane:

Ukubuka Konke Komkhiqizo

I-Phthalic Anhydride (PA) iyinto ebalulekile yamakhemikhali ephilayo, ekhiqizwa kakhulu yi-oxidation ye-ortho-xylene noma i-naphthalene. Ibonakala njengekristalu elimhlophe elinephunga elincane elicasulayo. I-PA isetshenziswa kabanzi ekukhiqizweni kwama-plasticizer, ama-polyester resins angagcwali, ama-alkyd resins, amadayi, kanye nemibala, okwenza kube yindawo ebalulekile embonini yamakhemikhali.

Izici Eziyinhloko

• Ukusabela Okuphezulu:I-PA iqukethe amaqembu e-anhydride, asabela kalula kuma-alcohols, ama-amine, kanye nezinye izinto ukuze akhe ama-ester noma ama-amides.
• Ukuncibilika Okuhle:Incibilika emanzini ashisayo, ama-alcohol, ama-ether, kanye nezinye izinyibilikisi eziphilayo.
• Ukuzinza:Izinzile ngaphansi kwezimo ezomile kodwa i-hydrolyze kancane kancane ibe yi-phthalic acid uma kukhona amanzi.
• Ukuguquguquka:Isetshenziswa ekuhlanganiseni imikhiqizo eminingi yamakhemikhali, okwenza kube lula kakhulu ukuyisebenzisa.

Izicelo

1. Izinto zokwenziwa ngepulasitiki:Isetshenziselwa ukukhiqiza ama-ester e-phthalate (isb., i-DOP, i-DBP), asetshenziswa kabanzi emikhiqizweni ye-PVC ukuthuthukisa ukuguquguquka kanye nokucutshungulwa kalula.
2. Ama-Resins e-Polyester Angagcwali:Isetshenziswa ekwenziweni kwe-fiberglass, izembozo, kanye nezinamathiselo, inikeza izakhiwo ezinhle kakhulu zemishini kanye nokumelana namakhemikhali.
3. Ama-resin e-Alkyd:Isetshenziswa kupende, ukumbozwa, kanye nama-varnish, okunikeza ukunamathela okuhle nokucwebezelayo.
4. Amadayi kanye nama-Pigment:Isebenza njengomxhumanisi ekuhlanganisweni kwamadayi nama-pigment e-anthraquinone.
5. Ezinye Izinhlelo Zokusebenza:Kusetshenziswa ekukhiqizweni kwemithi exubile, izibulala-zinambuzane, kanye namaphunga.

Ukupakisha Nokugcina Izinto

• Ukupakisha:Itholakala ngezikhwama ezingama-25 kg/isikhwama, ezingama-500 kg/isikhwama, noma ezingamathani. Izinketho zokupakisha ezenziwe ngokwezifiso ziyatholakala uma ucela.
• Isitoreji:Gcina endaweni epholile, eyomile, futhi enomoya omuhle. Gwema ukuthintana nomswakama. Izinga lokushisa elinconywayo lokugcina: 15-25℃.

Izinto Okufanele Uzicabangele Zokuphepha Nezemvelo

• Ukucasuka:I-PA iyacasula isikhumba, amehlo, kanye nohlelo lokuphefumula. Imishini yokuzivikela efanele (isib. amagilavu, izibuko, ama-respirator) kumele igqokwe ngesikhathi sokuphatha.
• Ukuvutha:Iyasha kodwa ayishisi kakhulu. Gcina kude namalangabi avulekile kanye namazinga okushisa aphezulu.
• Umthelela Wezemvelo:Lahla izinto ezilahliwe ngokuhambisana nemithetho yendawo yemvelo ukuze uvimbele ukungcola.
