Phthalic anhydride (PA) i-CAS NO.: 85-44-9

Incazelo emfushane:

Ukubuka konke komkhiqizo

I-Phthalic Anhydride (PA) iyinto ebalulekile yamakhemikhali yamakhemikhali e-organic, ekhiqizwa ngokuyinhloko yi-oxidation ye-ortho-xylene noma naphthalene. Kuvela njenge-crystalline emhlophe eqinile enephunga elicasulayo elincane. I-PA isetshenziswa kabanzi ekukhiqizweni kwamapulasitiki, ama-polsester angenasisekelo, ama-alkyd resins, amadayi kanye nemibala, okwenza kube ngumphakathi obalulekile embonini yamakhemikhali.

Izici ezibalulekile

• Ukuvuselelwa okuphezulu:I-PA iqukethe amaqembu anhydride, asabela kalula ngotshwala, ama-andines, namanye amakhompiyutha ukwakha ama-esters noma ama-Alides.
• I-Solubity enhle:Incibilika emanzini ashisayo, ama-alcohols, izitha, nakwamanye ama-solvents ezi-organic.
• Ukuqina:Uzinzile ngaphansi kwezimo ezomile kodwa ama-hydrolyzes ahamba kancane ukuze axhumeke i-phthalic acid ebukhoneni bamanzi.
• Okuhlukahlukene:Kusetshenziswe ekuhlanganiseni kwezinhlobonhlobo zemikhiqizo yamakhemikhali, okwenza kube yinhlelonhlobo kakhulu.

Izinja

1. Amapulasitiki:Kusetshenziselwa ukukhiqiza ama-Phthalate EPERS (isib., DOP, DBP), esetshenziswa kabanzi kwimikhiqizo ye-PVC ukuthuthukisa ukuguquguquka nokusebenza.
2. Ama-polyester angenasisekelo e-polyester:Kusetshenziswe ekwenziweni kwe-fiberglass, ukumboza, kanye nama-adhesives, kunikeza izakhiwo ezinhle kakhulu zemishini kanye nokumelana kwamakhemikhali.
3. I-Alkyd Resins:Kusetshenziswe kupende, ukumboza, kanye nama-varnish, ukuhlinzeka ngesibalo esihle kanye ne-gloss.
4. Udayi kanye nemibala:Isebenza njengomphakathi ngokuhlanganiswa kodayi kanye nodayi kanye nemibala.
5. Ezinye izinhlelo zokusebenza:Kusetshenziswe ekukhiqizeni imiphakathi yezemithi, ama-pesticides namakha.

Ukupakishwa nesitoreji

• Ukupakishwa:Kutholakala ku-25 kg / bag, 500 kg / bag, noma izikhwama zethani. Izinketho zokupakisha ngokwezifiso ziyatholakala ngesicelo.
• Isitoreji:Gcina endaweni epholile, eyomile futhi enomoya omuhle. Gwema ukuxhumana nomswakama. Ukushisa okunconyiwe kokugcina: 15-25 ℃.

Ukuphepha nokucatshangelwa kwemvelo

• Ukucasuka:I-PA iyacasula esikhunjeni, emehlweni nasezinhlelweni zokuphefumula. Imishini efanelekile yokuvikela (isib. Amagilavu, ama-goggles, ama-respirators) kumele agqoke ngesikhathi sokuphatha.
• Ukuvutha:Okuhlangene kodwa kungavuleki kakhulu. Gcina kude namalangabi avulekile kanye namazinga okushisa aphezulu.
• Umthelela Wezemvelo:Lahla izinto zokungcola ngokuya ngemithetho yendawo yokuvikela ukungcoliswa.

Xhumana nathi

Ngeminye imininingwane noma ukucela isampula, sicela uxhumane nethimba lethu lokuthengisa. Sizibophezele ekuhlinzekeni imikhiqizo esezingeni eliphakeme kanye nensizakalo enhle kakhulu!
