Isingeniso
I-Boric acid ibizwa nangokuthi "i-orthoboric acid". Itholakala ekusebenzisaneni phakathi kwe-borax yemvelo (i-sodium borate) ne-asidi. Ifomula yamakhemikhali i-H3BO3. Isisindo se-molecule 61.83. Izikali ze-triclinic ezimhlophe ezinamakristalu acwebezelayo. Ukuminyana okuhlobene ngu-1.43514, futhi inkomba ye-refractive ingu-1.337, 1.461, kanye no-1.462. Incibilika emanzini, i-ethanol Chemicalbook ne-glycerol. Isixazululo esinamanzi sine-acidic futhi siyi-asidi ebuthakathaka e-monovalent (Ka=6×10-10). Ukuncibilika emanzini kukhuphuka ngezinga lokushisa. Ishisiswe ibe ngu-169℃ (±1℃), ukuphelelwa amanzi emzimbeni kuzokhiqiza i-metaboric acid, futhi u-300℃ izokwakha i-boric anhydride. Hlukanisa phakathi ne-alkali enamandla ukuze uthole i-metaborate. I-Tetraborate itholakala ngaphansi kwezimo ezibuthakathaka ze-alkaline.
Impahla
Indlela yokulungiselela: I-Hydrochloric acid noma i-sulfuric acid ingafakwa kwisisombululo se-borax, noma ingatholakala ngokubola i-boraxite nge-hydrochloric acid. Ukusetshenziswa: Kusetshenziswa kakhulu ekukhiqizeni i-borate, ingilazi yamanzi, i-borate ester, ingilazi yamakhemikhali optical, uqweqwe lwawo, upende, umbala, izimonyo, izilondolozi zokudla, ukuqedwa kwesikhumba, ukuphrinta nokudaya izinsiza nemithi, njll. Ingasetshenziswa futhi njengesibulala-magciwane isibulala-magciwane, i-astringent.
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.
