Igama Lomkhiqizo:I-phthalic anhydride
Ifomethi ye-Molecular:I-C8H4O3
Inombolo ye-CAS:85-44-9
Isakhiwo samangqamuzana omkhiqizo:
I-Phthalic anhydride iyinhlanganisela yemvelo enefomula ethi C6H4(CO)2O.I-anhydride ye-phthalic acid.Lesi sici esiqinile esingenambala siyikhemikhali ebalulekile yezimboni, ikakhulukazi ukukhiqizwa okukhulu kwamapulasitiki opulasitiki
.I-Phthalic anhydride iyikhemikhali ebalulekile emaphakathi embonini yepulasitiki okutholakala kuyo ama-phthalate ester amaningi asebenza njengama-plasticizer kuma-synthetic resins.I-Phthalic anhydride ngokwayo isetshenziswa njenge-monomer kuma-synthetic resins njenge-glyptal, ama-alkyd resins, nama-polyester resins.
I-Phthalic anhydride iphinde isetshenziswe njengesandulela se-anthraquinone, i-phthalein, i-rhodamine, i-phthalocyanine, i-fluorescein, nodayi be-xanthene.
I-Phthalic anhydride isetshenziswa ekuhlanganiseni ama-amine ayinhloko, isikhunta sezolimo i-phaltan, ne-thalidomide.Okunye ukusabela nge-phthalic anhydride kukhiqiza i-phenolphthalein, i-benzoic acid, i-phthalylsulfathiazole (i-ejenti elwa namagciwane emathunjini), kanye ne-orthophthalic acid.
I-compound iyikhemikhali ephezulu ye-tonnage futhi isetshenziswa kabanzi ezinhlobonhlobo zama-organic syntheses ezimbonini.
I-Phthalic anhydride isetshenziswa ekwenzeni ama-polyester angagcwele futhi njenge-ejenti yokwelapha ama-epoxy resins.Uma isetshenziswa njenge-pigment, ingaba nesibopho sokuzwela kubasebenzi be-ceramic.
I-Phthalic Anhydride iyinhlanganisela ephilayo kanye ne-anhydride ye-phthalic acid (P384480).I-Phthalic Anhydride iyikhemikhali ebalulekile yezimboni evame ukusetshenziswa ekukhiqizeni ngezinga elikhulu ama-plasticizers f noma amapulasitiki.Ucwaningo lwakamuva luphinde lwahlola i-Phthalic Anhydride njenge-ejenti elwa namagciwane engaba khona.
ukukhiqizwa kwama-phthalein, ama-phthalates, i-benzoic acid, i-indigo yokwenziwa, ama-resin okwenziwa (glyptal).
Okuphakathi Kwama-Plastizers, Opende, Odayi Nezingulube, Ama-Polyester Resins.
I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi:
1. Ezokuphepha
Ukuphepha kuyinto ehamba phambili yethu.Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka.Ngakho-ke, sidinga ukuthi ikhasimende liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcina impahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubheke isithasiselo se-HSSE emigomeni nemibandela yokuthengisa ngezansi).Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.
2. Indlela yokulethwa
Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza.Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).
Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.
3. Inani elincane le-oda
Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.
4.Inkokhelo
Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.
5. Amadokhumenti okulethwa
Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:
· I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele
· Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)
· Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo
· Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
