inoa mea kūʻai：Phthalic anhydride
ʻAno molekala:C8H4O3
No CAS:85-44-9
Huahana molecular structure:
ʻO ka Phthalic anhydride ka pūhui olaola me ke ʻano C6H4(CO)2O.ʻO ia ka anhydride o ka phthalic acid.ʻO kēia paʻa kala ʻole he mea ʻenehana koʻikoʻi no ka hana nui ʻana o nā plasticizers no nā plastics
.Phthalic anhydride he mea koʻikoʻi koʻikoʻi koʻikoʻi i loko o ka ʻoihana plastics kahi i loaʻa mai ai nā esters phthalate he nui e hana ana ma ke ʻano he plasticizers i nā resins synthetic.Hoʻohana ʻia ka Phthalic anhydride ma ke ʻano he monomer no nā resins synthetic e like me glyptal, nā alkyd resins, a me nā resins polyester.
Hoʻohana pū ʻia ka Phthalic anhydride ma ke ʻano he precursor o anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, a me xanthene dyes.
Hoʻohana ʻia ka Phthalic anhydride i ka synthesis o nā amine mua, ka phaltan fungicide mahiʻai, a me ka thalidomide.ʻO nā hopena ʻē aʻe me ka phthalic anhydride e loaʻa i ka phenolphthalein, benzoic acid, phthalylsulfathiazole (he mea hana antimicrobial intestinal), a me ka waikawa orthophthalic.
ʻO ka mea hoʻohui he kemika kiʻekiʻe-tonnage a hoʻohana nui ʻia i nā ʻano syntheses organik ʻenehana.
Hoʻohana ʻia ka Phthalic anhydride i ka hana ʻana i nā polyesters unsaturated a ma ke ʻano he mea hoʻōla no nā resins epoxy.Ke hoʻohana ʻia e like me ka puaʻa, hiki iā ia ke kuleana no ka sensitization i nā limahana keramika.
ʻO ka Phthalic Anhydride kahi mea hoʻohuihui a me ka anhydride o ka phthalic acid (P384480).ʻO Phthalic Anhydride kahi mea hoʻohana waiwai nui i hoʻohana pinepine ʻia i ka hana nui o nā plasticizers f a i ʻole plastics.Ua loiloi pū ka noiʻi hou i ka Phthalic Anhydride ma ke ʻano he antibacterial agent.
ka hana ʻana i nā phthaleins, phthalates, benzoic acid, synthetic indigo, artificial resins (glyptal).
Kūwaena no nā mea hoʻopalapala, nā pena, nā waiʻula a me nā puaʻa, polyester resins.
Hiki iā Chemwin ke hāʻawi i ka nui o nā hydrocarbons nui a me nā mea hoʻoheheʻe kemika no nā mea kūʻai aku ʻoihana.Ma mua o kēlā, e heluhelu i ka ʻike kumu e pili ana i ka hana ʻana me mākou:
1. Palekana
ʻO ka palekana kā mākou mea nui.Ma waho aʻe o ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike e pili ana i ka hoʻohana palekana a me ka hoʻohana ʻana i ka nohona o kā mākou huahana, ua paʻa pū mākou i ka hōʻoia ʻana e hōʻemi ʻia nā pilikia palekana o nā limahana a me nā mea hana ʻaelike i kahi liʻiliʻi kūpono a hiki.No laila, koi mākou i ka mea kūʻai aku e hōʻoia i ka hoʻokō ʻana i nā kūlana palekana kūpono no ka wehe ʻana a me ka mālama ʻana ma mua o kā mākou hoʻouna ʻana (e ʻoluʻolu e nānā i ka appendix HSSE ma nā ʻōlelo a me nā kūlana kūʻai ma lalo).Hiki i kā mākou mau loea HSSE ke hāʻawi i ke alakaʻi i kēia mau kūlana.
2. Keʻano hoʻouna
Hiki i nā mea kūʻai ke kauoha a hāʻawi i nā huahana mai chemwin, a i ʻole hiki iā lākou ke loaʻa nā huahana mai kā mākou hale hana.ʻO nā ʻano kaʻa kaʻa i loaʻa ke kaʻa kaʻa, kaʻaahi a i ʻole ka halihali multimodal (e pili ana nā kūlana kaʻawale).
I ka hihia o nā koi o ka mea kūʻai aku, hiki iā mākou ke kuhikuhi i nā koi o nā moku a i ʻole nā pahu pahu a kau i nā kūlana palekana / loiloi kūikawā a me nā koi.
3. Ka nui kauoha liʻiliʻi
Inā kūʻai ʻoe i nā huahana mai kā mākou pūnaewele, ʻo ka liʻiliʻi liʻiliʻi he 30 tons.
4. Uku
ʻO ke ala uku maʻamau ka unuhi pololei ʻana i loko o 30 mau lā mai ka invoice.
5. Nā palapala hoʻouna
Hāʻawi ʻia kēia mau palapala i kēlā me kēia hoʻouna:
· Bill of Lading, CMR Waybill a i ʻole nā palapala halihali e pili ana
· Palapala hōʻoia o ka nānā ʻana a i ʻole Conformity (inā koi ʻia)
· Nā palapala pili i ka HSSE e like me nā lula
· Nā palapala dute e like me nā lula (inā pono)
