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

Incazelo emfushane:

Uhlolojikelele Lomkhiqizo

I-Phthalic Anhydride (PA) iyi-organic chemical material eluhlaza, ekhiqizwa ngokuyinhloko yi-oxidation ye-ortho-xylene noma i-naphthalene. Kubonakala njengokuqinile okucwebezelayo okunephunga elincane elicasulayo. I-PA isetshenziswa kabanzi ekukhiqizeni ama-plasticizers, ama-polyester resins angasetshenzisiwe, ama-alkyd resins, odayi, nezingulube, okwenza kube okuphakathi okubalulekile embonini yamakhemikhali.

Izici Eziyinhloko

• Ukusebenza Okuphezulu:I-PA iqukethe amaqembu e-anhydride, asabela kalula ngotshwala, ama-amine, nezinye izinhlanganisela ukuze akhe ama-ester noma ama-amide.
• Ukunyibilika Okuhle:Incibilika emanzini ashisayo, utshwala, ethers, nezinye izincibilikisi eziphilayo.
• Ukuzinza:Izinzile ngaphansi kwezimo ezomile kodwa i-hydrolyzes kancane ibe yi-phthalic acid lapho amanzi ekhona.
• Ukuhlukahluka:Isetshenziswa ekuhlanganiseni uhla olubanzi lwemikhiqizo yamakhemikhali, okwenza ibe nezinto ezihlukahlukene kakhulu.

Izinhlelo zokusebenza

1. Ama-Plasticizers:Isetshenziselwa ukukhiqiza ama-phthalate esters (isb, i-DOP, i-DBP), asetshenziswa kakhulu emikhiqizweni ye-PVC ukuze kuthuthukiswe ukuguquguquka nokuguquguquka.
2. Ama-Polyester Resins Angasetshenzisiwe:Isetshenziswa ekwenzeni i-fiberglass, i-coatings, ne-adhesives, enikeza izakhiwo ezinhle kakhulu zemishini kanye nokumelana namakhemikhali.
3. I-Alkyd Resins:Isetshenziswa kumapende, ama-coatings, nama-varnish, ehlinzeka ukunamathela okuhle nokucwebezela.
4. Odayi nezingulube:Isebenza njengendawo emaphakathi ekuhlanganisweni kodayi be-anthraquinone nemibala.
5. Ezinye izinhlelo zokusebenza:Isetshenziswa ekukhiqizeni izinqamuleli zemithi, izibulala-zinambuzane, namakha.

Ukupakisha & Isitoreji

• Ukupakishwa:Itholakala nge-25 kg/bag, 500 kg/bag, noma izikhwama zamathani. Izinketho zokupakisha ngokwezifiso ziyatholakala uma ucelwa.
• Isitoreji:Gcina endaweni epholile, eyomile, futhi enomoya omuhle. Gwema ukuthintana nomswakama. Izinga lokushisa elinconyiwe lesitoreji: 15-25℃.

Ukuphepha Nemvelo

• Ukucasuka:I-PA iyacasula isikhumba, amehlo, kanye nesistimu yokuphefumula. Izimpahla zokuzivikela ezifanele (isb., amagilavu, izibuko, izinto zokuphefumula) kufanele zigqokwe ngesikhathi sokuphatha.
• Ukuvutha:Iyavutha kodwa ayivuthi kakhulu. Zigcine kude namalangabi avulekile namazinga okushisa aphezulu.
• Umthelela Wezemvelo:Lahla udoti ngokuhambisana nemithetho yendawo yendawo ukuze uvimbele ukungcola.
