Sulfuric acid ndi ntchito zake

chidulo cha safuriki ndi mmodzi wa mankhwala odziwika bwino kwambiri ndi wamba mankhwala. Chifukwa chake makamaka katundu bwino chimatanthauza. chilinganizo ake - H2SO4. Izi diacid ndi apamwamba makutidwe ndi okosijeni boma la sulfa +6.

M'mikhalidwe yachibadwa asidi sulfuric ndi madzi popanda fungo ndi mtundu, ndi makhalidwe wochuluka. Ambiri kufalitsa mu luso ndi mafakitale zosiyanasiyana.

Pa nthawi, mankhwala ndi imodzi mwa mankhwala ofunika kwambiri ndipo ambiri ndi mankhwala. Mu chikhalidwe, mbadwa madipoziti sulfure kudutsa si kawirikawiri monga ulamuliro, izo imapezeka mu mankhwala ndi zinthu zina. Ndi kusiyana kupanga mankhwala osiyanasiyana sulfure, kuphatikizapo zosiyanasiyana zinyansi mafakitale. Nthawi zina, mipweya zitsulo akakhala zikhoza kusinthidwa kutulutsa M'menemo sulfure ndi mankhwala osiyanasiyana.

katundu

chidulo cha safuriki kusokoneza aliyense pawiri organic. Pamafunika madzi mwamsanga kwambiri moti nsalu mankhwala osiyanasiyana anayamba Char. 100% asidi ndi imodzi mwa kwambiri, pawiri Kodi fodya ndi sichichititsa zitsulo akakhala.

Kuchepetsa asidi sulfuric amachitira ndi zitsulo wina osati patsogolo. Mu mawonekedwe kuikapo maganizo zimayamba oxidize zinthu zambiri.

The ntchito asidi sulfuric

Makamaka asidi sulfuric ntchito makampani mankhwala, kumene akuchokera zokolola asafe ndi feteleza mankwala, kuphatikizapo superphosphate, amene panopa ndi chimodzi cha feteleza ambiri. Chaka kubala matani mamiliyoni angapo thunthu.

Mu metallrugii H2SO4 ntchito aletse khalidwe la zinthu. Pamene adagulung'undisa zitsulo yaying'ono-ming'alu kumachitika kuti azindikire iwo, item aikidwa mu kusamba otsogolera unazokotedwa 25% njira ya acid. Pambuyo pake, ngakhale ming'alu zing'onozing'ono Tingaone ndi apoyera.

Patsogolo ntchito zitsulo plating m'pofunika kale kukonzekera - kutsukidwa ndi degreased. Popeza chidulo sulfuric amachitira ndi zitsulo, amasungunula wosanjikiza zoonda, ndi kuti amachotsa kuda aliyense kuipitsidwa. Komanso, pamwamba zitsulo amakhala wovuta umene uli bwino yoti ntchito ya faifi tambala, chromium kapena plating mkuwa.

chidulo cha safuriki ntchito processing wa ena ores, kumakhalanso kwambiri kuchuluka chofunika makampani mafuta kumene ntchito makamaka kwa kudziyeretsa mankhwala osiyanasiyana. Amagwiritsidwa ntchito kawirikawiri mu makampani mankhwala, amene nthawi zonse ikusintha. Chifukwa cha zimenezi, anapeza mphamvu zina ndipo ofunsira. Nkhanizi angagwiritsidwe ntchito yopanga kutsogolera-asidi magwero panopa - zosiyanasiyana mabatire.

Kukonzekera asidi sulfuric

Waukulu zopangira yopangira sulfure ndi zidulo kutumikira mankhwala osiyanasiyana ofotokoza. Komanso, monga tanenera kale, ndi kukhala ndi ntchito zoipa mafakitale kubala sulfure. Mu Kukuwotcha pa zobwera chifukwa cha okosijeni wa sulfide ores mpweya utsi muli SO2. Iwo ndinazolowera kubala asidi sulfuric. Ngakhale Russia akupitiriza kutenga udindo waukulu mu processing kupanga ofotokoza za galasi, amene watentha ng'anjo. Pamene mpweya wotentha pa pyrites ndi kupangidwa awiri SO2 mkulu. Kuchotsa zinyalala ndi nthuzi ena woopsawo electrostatic ntchito. Tsopano kupanga njira chimagwiritsidwa ntchito zosiyanasiyana yopangira asidi, ndipo ambiri a iwo zokhudzana ndi kuwononga kasamalidwe, ngakhale chiwerengero mkulu wa mafakitale chikhalidwe.
