Intshayelelo kunye nepropati
Intshayelelo
I-P-Phenylenediamine (isiNgesi i-p-Phenylenediamine), eyaziwa ngokuba yi-Ursi D, yenye yezona diamines ezinuka kamnandi. Imveliso esulungekileyo imhlophe ukuya kwikristale yelavender, ejika ibemfusa okanye ibemdaka omnyama xa ityhilekile emoyeni. Inyibilika kancinci kumanzi abandayo, inyibilika kwi-ethanol, ether, chloroform kunye nebenzene. Ingasetyenziselwa ukulungisa idayi ze-azo, iipolymers zemolekyuli ephezulu, kwaye ingasetyenziselwa ukuvelisa idayi zoboya, i-raber antioxidants kunye nabaphuhlisi beefoto iChemicalbook. Isetyenziswa ikakhulu kwi-aramid, idayi ye-azo, idayi yesulfure, idayi yeasidi, kwaye ingasetyenziselwa uboya. Ukuveliswa kwe-D emnyama, i-DB enoboya obuluhlaza, i-N2 enoboya obumdaka, kunye ne-rubber antioxidants DNP, DOP, kunye ne-MB. Ikwasetyenziswa njengemathiriyeli ekrwada yedayi yeenwele zokuthambisa i-Ursi D uthotho, inhibitor ye-polymerization yepetroli kunye nomphuhlisi. Njengedayi yeekhemikhali, i-p-phenylenediamine okwangoku ivunyelwe ukuba isetyenziswe ekuveliseni idayi yeenwele, kodwa kukho izithintelo ezicacileyo kubungakanani bokusetyenziswa.
Ipropati
Imhlophe ukuya kwiikristale zelavenda. Ijike ibemfusa okanye ibentsundu emnyama xa ibekwe emoyeni. Inyibilika emanzini, ethanol, ether, chloroform kunye nebenzene. Yidayi ebalulekileyo ephakathi kwaye isetyenziswa ikakhulu ukwenza iidayi ze-azo kunye nedayi yesulfure. Isenokusetyenziswa ukuvelisa uboya D emnyama kunye nerabha antioxidant DNP. Isetyenziswe njengesalathisi se-fluorescent, i-reagent yokuhlalutya kunye nedayi yoboya, kwaye isetyenziswe kwi-synthesis yedayi.
Iingcebiso
Molo, ndiyavuya ukudibana nawe apha. Ngaba unomdla kule mveliso? Le mveliso ibekwe kum kwiishelufu. Ndiyazi kakhulu ngale mveliso. Ukuba ufuna naluphi na uthethwano, unganditsalela nangaliphi na ixesha kwaye uzame ukukubonelela ngezona nkonzo zanelisayo zangaphambili kunye neenkonzo zasemva kokuthengisa. Iinkcukacha zam zoqhagamshelwano zingezantsi, wamkele imibuzo yakho.

Iphakheji
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.
Ukuthuthwa ngomoya nolwandle zezona ziphambili, zongezwa kuthutho lwelori kunye nokuthuthwa kweelori. Ukuthuthwa kwethu phantse zonke iinkonzo zendlu ngendlu, ukugqiba imvume yesithethe phakathi kwelizwe elithumela ngaphandle kunye nelizwe elithumelayo, ngaphandle kweemeko ezikhethekileyo kwamanye amazwe okanye kwimimandla.
umzi-mveliso kunye neWarehouse
Umzi-mveliso wethu unemveliso yonyaka ezinzileyo yeetoni ezingama-50,000 zemathiriyeli ekrwada unyaka wonke. Ikhonkco lemveliso kunye nekhonkco lokuthengisa liyaqhubeka nokuhlutha. Indawo yethu yokugcina inomthamo omkhulu womgubo kunye nesitokhwe solwelo. Siyabamkela abantu abavela kuzo zonke iinkalo zobomi ukuba baxhase kwaye basebenzisane.
