Lapho ukuthenga sulfuric acid? yokuthengisa esiqokiwe nezeluleko

Akubona bonke zokwakha kanye reagents manje okudayisa khulula. Enye yalezi izinto kunzima sulfuric acid. Esizoyicabangela kulesi sihloko, lokho kuhilela futhi lapho angathengwa emizini Russian.

Sulfuric acid - a ... Ezokuthutha, isitoreji

Umangele lapho ungakwazi ukuthenga sulfuric acid, khumbula wokuqala mayelana izakhiwo le yingozi kubantu. Sulfuric acid kuyinto uhlobo dibasic asidi enamandla, ifomula ayo - H _{2 4 SO.} ERussia, le ngxube sulphur trioxide namanzi ikhiqizwa ngokuvumelana GOST 667-73, 2184-77, 4240-77. Womshini esindayo ketshezi oily okuyinto akanayo umbala noma iphunga sihilela izinhlobo eziningana, okuyinto zingafani ubumsulwa babo kanye okuhlushwa.

Sulfuric acid ine Izakhiwo ezilandelayo ezibalulekile:

• Gravity Specific - 1.85 g / cm ³ (e okuvezwa ngokuphelele sulfuric acid - 1,92 g / cm ^3, kodwa yalolu ketshezi has ethile abalulekile - iqandiswe -10 degrees centigrade).
• Abilayo iphuzu - +296,5 ^° centigrade, iphuzu crystallization - + 10,45 ° Celsius.
• Ngezinye lokuhlala kufika ku-70% phakathi Ukushisa nokubilisa lokhu acid abelwe umhwamuko kuphela. Ngezinye okuqukethwe ephakeme ka H ₂ SO ₄ emoyeni futhi bayasilela eziyingozi acid excretion.
• izidakamizwa obhubhisayo oluvuthayo. Lapho ukuxhumana amanzi okumelwe esatshwe ukuphendula enobudlova, okuholela amagesi kwazivelela, evala, ukushisa. Yingakho lapho esebenza sulfuric acid kuyadingeka ukuba izingubo ezikhethekile, izicathulo, iqoqo ngabanye ukuvikelwa amakhemikhali.

Kuthunyelwe kuze kube sekupheleni umsebenzisi sulfuric acid kokubili imigwaqo emikhulu nojantshi bezitimela ezokuthutha. Ukuze uzulazule usebenzisa iziqukathi ekhethekile sulfuric acid (i-technical sulfuric acid) noma ithangi acid nemithi (i ngcono H _{2 4 SO).}

Phakathi isitoreji kuwufanele ukukhumbula ukuthi sulfuric acid - ikhemikhali enobuthi okuqondene ekilasini ingozi yesibili. Umkhawulo lokuhlushwa okuphephile umusi H ₂ SO ₄ - 1 mg / m ^3. Ngaphambi kokuba unqume kuphi ukuthenga sulfuric acid (technical), udinga ukuthenga iziqukathi ekhethekile yokugcina. Ekukhiqizeni yayo izindawo eminye obkladyvayut acid nemithi isitini.

Ukusetshenziswa sulfuric acid

I abathengi eyinhloko sulfuric acid - a umkhakha steel, ukhuni ukucutshungulwa izitshalo, amakhemikhali umkhakha. It isetshenziswa:

• elihlanza uwoyela kusukela sulphur inclusions;
• noqhekeko ore;
• descaling phambi wire lashukumisa, uthayela;
• nickel Plating, chromium Plating surface metal;
• ukukhiqizwa kwemikhiqizo yasekhemisi (isixazululo bagxila zamagama organic);
• ukukhiqizwa Umanyolo (kulomkhakha ibusa cishe ingxenye yabantu sulfuric acid ekhiqizwa kuleli zwe);
• the Ukuze kwenziwe imicu ekhiqizwa yokufakelwa;
• ukukhiqizwa ETHYL utshwala;
• zokukhiqiza udayi aniline.

Abantu abanentshisekelo lapho ukuthenga sulfuric acid, it is okungcono esetshenziswa njengoba electrolyte for nomthofu-acid amabhethri.

Lapho ukuthenga sulfuric acid

Ekhemisi sulfuric acid ungalithengisi nhlobo. Umuntu angase zithole isixazululo yayo non-kanzulu (30-35%) ezitolo, eqaphela auto izingxenye kanye amakhemikhali yezimoto. izixazululo Okuningi kanzulu - kuyisandulela abantu ngubani ngokomthetho kungukuthi ithengiswe.

Ubani benzile yokufuna enjalo ngaphambi kokwazi lapho ukuthenga sulfuric acid, ukunikeza izeluleko abantu.

Amathiphu Ukuthenga

Ngakho, kubalulekile ukuba bakhumbule lokhu okulandelayo:

1. Umuntu yangasese, ezimweni ezingajwayelekile, ithengiswe semali yalolu ketshezi - kufanele kancane kancane sizuza, kusukela abahlinzeki ahlukahlukene.
2. Uma kwenzeka ukwehluleka yokufuna Ungazama futhi vaporize H ₂ SO ₄ electrolyte. I kwabantu esiphezulu ngaleyo ndlela ngeke ezingaphezu kuka 1.4 g / cm ^3. Ukuhwamuka Kwenziwa esitsheni zobumba ku okugeza isihlabathi noma Gypsum. Kunoma ikuphi akunakwenzeka ukwenza le nqubo endlini.
3. Khumbula ukuthi ukuthengiswa sulfuric acid esilawulwa, njengoba Le into isetshenziswa ukukhiqiza izidakamizwa, kanye neziqhumane ezenziwe ekhaya. Ngisho noma ukuthole uvivinyo elingenacala noma refilling avtoakkumulyatora izinto eziningi ze-non-ezincane, kungabangela izinsolo ezingadingekile.

Ngingalutholaphi ukuthenga sulfuric acid eMoscow

Enhloko-dolobha ukuthenga sulfuric acid kungaba ku:

• "Himmede";
