Intshayelelo kunye nepropati
Intshayelelo
Igama lekhemikhali ye-acetaminophen yi-N-(4-Hydroxyphenyl) i-acetamide (N-(4-Hydroxyphenyl) i-acetamide), kunye negama layo lokurhweba yi-paracetamol, eyeklasi ye-acetanilide ye-antipyretic kunye ne-analgesics. Yaqala ukwenziwa nguMorse ngo-1878 kwaye yaqala ukusetyenziswa ekliniki nguVon Mering ngo-1893. Yaba lichiza elithengiswayo e-United States ngo-1955, kwaye imveliso yaqala kwilizwe lam ekupheleni kwe-1950s. Imbonakalo yayo yikristale emhlophe okanye i-crystalline powder, ene-melting point ye-168-172 ° C, i-odorless, incasa ekrakra, i-soluble ngokulula emanzini ashushu okanye i-ethanol, i-soluble kwi-acetone, kwaye iphantse ingabi namanzi abandayo kunye ne-petroleum ether.
Ipropati
I-acetaminophen isebenza njenge-antipyretic ngokuvimbela ukuhlanganiswa kwe-prostaglandin kwiziko le-hypothalamic thermoregulatory center. Impembelelo yayo ye-antipyretic ifana ne-aspirin. Iveliswa ngokuthintela ukuhlanganiswa kwe-prostaglandin kwinkqubo ye-nervous central kunye nokuthintela iimpembelelo zentlungu ye-nerve endings. Inomphumela we-analgesic obuthathaka kunalowo we-aspirin. Xa kuthelekiswa ne-aspirin, ineengenelo zokungacaphuki kancinci kunye nokungahleleki komzimba. I-antipyretic kunye ne-analgesic effect ifana ne-phenacetin.

Kwifomu yomgubo, ubungakanani bomyalelo bungaphantsi kwama-25 kg. Ifakwe kwingxowa yeplastiki kunye ne-aluminium foil bag, kwaye umaleko ongaphandle upakishwe kwibhokisi.
I-25kg nangaphezulu, ipakishwe kwaye yapakishwa kwidramu yekhadibhodi eneengxowa ezicacileyo ezakhelwe ngaphakathi kunye neengxowa zefoyile ye-aluminiyam.
Ezinye iimveliso zeekhemikhali eziqhelekileyo zithunyelwa ngokuthe ngqo kwiingxowa.
Kwifomu yolwelo, ngaphantsi kwe-25 kg. Ipakishwe kwiindidi ezahlukeneyo zemibhobho yekhemikhali. Iimveliso zexabiso eliphezulu kunye nendalo ye-R & D ziya kuthunyelwa kwiibhotile ezine-fluorinated.
Iimveliso ze-25 kg nangaphezulu ziya kuthunyelwa kwi-25 kg okanye i-50 kg imibhobho yekhemikhali njengeyunithi esisiseko.
Ukuhambisa ngenqanawe
Iiodolo ezifakwe ngaphambi kwentsimbi ye-17:00 ukususela ngoMvulo ukuya ngoLwesihlanu ziya kuthunyelwa ngokubanzi zisuka kumzi-mveliso zisiwe kumhambisi wempahla kwangolo suku lunye (ngokuqhelekileyo azithunyelwa ngeempelaveki), yaye ziya kufika kumthumeli wempahla malunga neentsuku ezintathu ukuya kwezine.
Umthumeli wempahla uya kukhupha inombolo yokulandelela kumazwe ngamazwe ngosuku okanye ngosuku olulandelayo lokufika.
Ngokuxhomekeke kwilizwe, siya kusebenzisa iindlela ezahlukeneyo zokuthumela ngenqanawa. Ngokuqhelekileyo, imigca enikezelweyo, i-logistics kunye neenkonzo zeposi zizona ziphambili, kwaye ezinye ziya kuthumela kwi-DHL, Fedex, UPS, njl.
