Isingeniso kanye nempahla
Isingeniso
I-P-Phenylenediamine (isiNgisi p-Phenylenediamine), eyaziwa nangokuthi i-Ursi D, ingenye yama-diamine anephunga elimnandi. Umkhiqizo omsulwa umhlophe ukuya ku-lavender crystal, ephenduka onsomi noma onsundu ngokumnyama lapho uvezwe emoyeni. Incibilika kancane emanzini abandayo, i-ethanol, i-ether, i-chloroform ne-benzene. Ingasetshenziselwa ukulungisa odayi be-azo, ama-polymers aphezulu wamangqamuzana, futhi ingasetshenziswa futhi ukukhiqiza odayi boboya, ama-antioxidants enjoloba kanye nabathuthukisi bezithombe I-Chemicalbook. Isetshenziselwa ikakhulukazi ama-aramid, odayi be-azo, odayi besibabule, odayi be-asidi, futhi ingasetshenziselwa uboya. Ukukhiqizwa kwe-black D, i-DB emnyama enoboya eluhlaza okwesibhakabhaka, i-N2 enoboya obunsundu, kanye nama-antioxidants erabha i-DNP, i-DOP, ne-MB. Ibuye isetshenziswe njengempahla eluhlaza ochungechungeni lwedayi yezinwele zezimonyo i-Ursi D, inhibitor ye-polymerization kaphethiloli kanye nonjiniyela. Njengodayi wamakhemikhali, i-p-phenylenediamine okwamanje ivunyelwe ukusetshenziswa ekukhiqizeni amadayi ezinwele, kodwa kunemikhawulo ecacile mayelana nenani lokusetshenziswa.
Impahla
Amakristalu amhlophe kuya ku-lavender. Iba nsomi noma ibe nsundu ngokumnyama uma ichayeke emoyeni. Incibilika emanzini, i-ethanol, i-ether, i-chloroform ne-benzene. Kungudayi obalulekile ophakathi nendawo futhi usetshenziswa kakhulu ukwenza odayi be-azo kanye nodayi besibabule. Ingase futhi isetshenziselwe ukukhiqiza uboya D obumnyama kanye nerabha antioxidant DNP. Isetshenziswa njengenkomba ye-fluorescent, i-reagent yokuhlaziya kanye nodayi woboya, futhi isetshenziselwa ukuhlanganiswa kodayi.
Amathiphu
Sawubona, ngiyajabula ukukwazi lapha. Ingabe unentshisekelo kulo mkhiqizo? Lo mkhiqizo ubekwe yimi emashalofini. Ngazi okuningi ngalo mkhiqizo. Uma udinga noma yikuphi ukubonisana, ungangithinta nganoma isiphi isikhathi futhi ulwele ukukunikeza ngezinkonzo zokuthengisa zangaphambi kokuthengisa kanye nezangemuva kokuthengisa ezanelisa kakhulu. Imininingwane yami yokuxhumana ingezansi, wamukelekile imibuzo yakho.

Iphakheji
Ngefomu lempushana, inani le-oda lingaphansi kwama-25 kg. Ipakishwe esikhwameni sepulasitiki kanye nesikhwama se-aluminium foil, futhi ungqimba olungaphandle lupakishwe ebhokisini.
25kg nangaphezulu, ipakishwe futhi yapakishwa esigubhuni sekhadibhodi esinezikhwama ezikhanyelayo ezakhelwe ngaphakathi kanye nezikhwama ze-aluminium foil
Eminye imikhiqizo yamakhemikhali evamile ithunyelwa ngqo ezikhwameni.
Isesimweni esiwuketshezi, esingaphansi kwama-25 kg. Ipakishwe ngezinhlobo ezahlukene zemiphongolo yamakhemikhali. Imikhiqizo yenani eliphezulu enemvelo ye-R&D izothunyelwa ngamabhodlela ane-fluorinated.
Imikhiqizo engama-25 kg nangaphezulu izothunyelwa ngemiphongolo yamakhemikhali engu-25 kg noma engu-50 kg njengeyunithi eyisisekelo.
Ukuthumela ngomkhumbi
Ama-oda afakwe ngaphambi kuka-17:00 kusukela ngoMsombuluko kuya kuLwesihlanu ngokuvamile azothunyelwa esuka efekthri aye kumthumeli wezimpahla ngalolo suku (ngokuvamile awathunyelwa ngezimpelasonto), futhi azofika kumthumeli wezimpahla cishe ezinsukwini ezintathu kuya kwezine.
Umthumeli wempahla uzokhipha inombolo yokulandelela yomhlaba wonke ngosuku noma ngosuku olulandelayo lokufika.
Kuye ngezwe, sizosebenzisa izindlela ezahlukene zokuthutha. Ngokuvamile, olayini abazinikele, izinto zokuthutha kanye nezinsizakalo zeposi yizona eziyinhloko, kanti ezinye zizothunyelwa ku-DHL, Fedex, UPS, njll.
Ezokuthutha ngomoya nolwandle yizona ezihamba phambili, ezenezelwa ezokuthutha zamaloli kanye nezokuthutha zamaloli. Ukuthutha kwethu cishe kuzo zonke izinsiza zendlu ngendlu, ukuqedela imvume yempahla phakathi kwezwe elithumelayo kanye nezwe elingenisayo, ngaphandle kwezimo ezikhethekile kwamanye amazwe noma izifunda.
ifektri & Isitolo
Imboni yethu inomkhiqizo ozinzile wonyaka wamathani angama-50,000 wezinto ezingavuthiwe unyaka wonke. Uchungechunge lokukhiqiza kanye nochungechunge lokuthengisa luyaqhubeka nokugcwala. Indawo yethu yokugcina impahla inesitoko esikhulu sempushana nezitokwe eziwuketshezi. Samukela abantu abavela kuzo zonke izizinda ukuze baseseke futhi babambisane.
