Mtundu wa Molecular:C8H4O3
CAS No:85-44-9
Kapangidwe kazinthu zama cell:
Phthalic anhydride ndi organic pawiri ndi chilinganizo C6H4(CO)2O.Ndi anhydride wa phthalic acid.Cholimba chopanda mtunduchi ndi chinthu chofunikira kwambiri m'mafakitale, makamaka pakupanga kwakukulu kwa mapulasitiki apulasitiki
.Phthalic anhydride ndi mankhwala ofunikira apakati pamakampani apulasitiki omwe amachokera ku ma ester ambiri a phthalate omwe amagwira ntchito ngati mapulasitiki mu utomoni wopangira.Phthalic anhydride palokha imagwiritsidwa ntchito ngati monomer pazopangira zopangira monga glyptal, alkyd resins, ndi ma polyester resins.
Phthalic anhydride imagwiritsidwanso ntchito ngati kalambulabwalo wa anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, ndi xanthene utoto.
Phthalic anhydride imagwiritsidwa ntchito popanga amines oyambira, fungicide phaltan, ndi thalidomide.Zochita zina ndi phthalic anhydride zimatulutsa phenolphthalein, benzoic acid, phthalylsulfathiazole (m'mimba antimicrobial agent), ndi orthophthalic acid.
Pagululi ndi mankhwala okwera kwambiri ndipo amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana opanga ma organic syntheses.
Phthalic anhydride imagwiritsidwa ntchito popanga ma polyesters osapangidwa ndi unsaturated komanso ngati machiritso a epoxy resins.Akagwiritsidwa ntchito ngati pigment, amatha kukhala ndi udindo wolimbikitsa anthu ogwira ntchito za ceramic.
Phthalic Anhydride ndi organic pawiri ndi anhydride wa phthalic acid (P384480).Phthalic Anhydride ndi mankhwala ofunikira m'mafakitale omwe amagwiritsidwa ntchito kwambiri popanga mapulasitiki kapena mapulasitiki.Kafukufuku waposachedwa adawonanso kuti Phthalic Anhydride ngati antibacterial wothandizira.
kupanga phthaleins, phthalates, benzoic acid, synthetic indigo, ma resins opangira (glyptal).
Zapakatikati Zopangira Plastizer, Paint, Dyes ndi Pigment, Polyester Resins.
Chemwin ikhoza kupereka ma hydrocarbon ambiri ambiri ndi zosungunulira zamankhwala kwa makasitomala aku mafakitale.Izi zisanachitike, chonde werengani mfundo zotsatirazi zokhuza kuchita bizinesi nafe:
1. Chitetezo
Chitetezo ndicho chofunikira kwambiri chathu.Kuphatikiza pa kupatsa makasitomala chidziwitso chokhudza kugwiritsa ntchito bwino komanso kusamala zachilengedwe kwa zinthu zathu, tadziperekanso kuwonetsetsa kuti chiwopsezo chachitetezo cha ogwira ntchito ndi makontrakitala chikuchepetsedwa kukhala chocheperako komanso chotheka.Choncho, tikufuna kuti kasitomala awonetsetse kuti miyezo yoyenera yotsitsa ndi kusunga chitetezo ikukwaniritsidwa tisanaperekedwe (chonde onani zowonjezera za HSSE pazogulitsa zomwe zili pansipa).Akatswiri athu a HSSE atha kupereka chitsogozo pamiyezo iyi.
2. Njira yobweretsera
Makasitomala amatha kuyitanitsa ndikutumiza zinthu kuchokera ku chemwin, kapena atha kulandira zinthu kuchokera kumakampani athu opanga.Njira zoyendera zomwe zilipo zikuphatikiza magalimoto, njanji kapena ma multimodal (mikhalidwe yosiyana imagwira ntchito).
Pankhani ya zofuna za makasitomala, titha kufotokoza zofunikira za mabwato kapena akasinja ndikugwiritsa ntchito miyezo yapadera yachitetezo / kuwunika ndi zofunikira.
3. Kuchuluka kwa dongosolo lochepa
Ngati mumagula zinthu patsamba lathu, kuchuluka kwa madongosolo ocheperako ndi matani 30.
4.Kulipira
Njira yolipirira yokhazikika imachotsedwa mwachindunji mkati mwa masiku 30 kuchokera pa invoice.
5. Zolemba zotumizira
Malemba otsatirawa amaperekedwa pakubweretsa kulikonse:
· Bill of Lading, CMR Waybill kapena chikalata china chamayendedwe
· Satifiketi Yowunikira kapena Yogwirizana (ngati pakufunika)
· Zolemba zokhudzana ndi HSSE mogwirizana ndi malamulo
· Zolemba za kasitomu mogwirizana ndi malamulo (ngati pakufunika)
