Sulphuric acid - a ... Transport, ukugcinwa

Bezibuza apho unokuthenga sulphuric acid, uwabize yokuqala malunga neempawu oku ayingozi ebantwini. Sulphuric acid luhlobo of a dibasic acid enamandla, ifomula wayo - H ₂ SO _4. ERashiya, le umxube sulphur trioxide namanzi iveliswa ngokwe GOST 667-73, 2184-77, 4240-77. Eyimveliso ulwelo enzima olunamafutha leyo alinayo nayiphi na umbala okanye ivumba, luquka iintlobo eziliqela, eziya kwahluka ngobunyulu zabo ingqondo.

Sulphuric acid na iimpawu ibalulekileyo ilandelayo:

• Gravity ngqo - 1,85 g / cm ³ (in an sulphuric acid ifanelekileyo ndawo ingundoqo - 1,92 g / cm ^3, kodwa ke le nto iye ethile ebalulekileyo - emkhenkceni -10 ° C).
• Ukupheka point - +296,5 ^° C, indawo crystallization - + 10,45 ° Celsius.
• Xa lamanani ukuya kwi-70% ngexesha zokufudumeza nokubilisa kwalo acid zabiwa kuphela umphunga wamanzi. Xa imixholo aphezulu H ₂ SO ₄ emoyeni kwaye bawe acid zinomgutyulo yingozi.
• izinto neziqhushumbisi kananjalo ezinokutsha. Phezu contact ngamanzi ukuba kukoyikwa indlela ugonyamelo, nto leyo iigesi sazivelela, umphunga, ubushushu. Yiyo loo nto xa usebenza nge-sulphuric acid kuyimfuneko ukuba iimpahla ezikhethekileyo, izihlangu, iseti wokhuseleko kwemichiza ngamnye.

Sahlangulwa ekupheleni yomsebenzisi sulphuric acid zombini indlela kunye nezithuthi yoololiwe. Ukuze indlela ngokusebenzisa izingxobo ezikhethekileyo sulphuric acid (for sulphuric acid technical) okanye itanki acid-resistant (oluphuculweyo H ₂ SO _4).

Ngexesha yokugcina kubalulekile ukukhumbula ukuba sulphuric acid - into zinetyhefu ukubayinxalenye yesibini udidi ingozi. Ubuninzi xi ekhuselekileyo ekhasa H ₂ SO ₄ - 1 mg / m ^3. Phambi kokuba ugqibe apho ukuthenga sulphuric acid (technical), kufuneka ukuba bathenge izikhongozeli ezikhethekileyo zokugcina. Kwizibonelelo imveliso yawo ngakumbi obkladyvayut izitena acid ezingatshiyo.

Ukusetyenziswa kwe-sulphuric acid

Eyona engundoqo abathengi sulphuric acid - kushishino sentsimbi a, izityalo iinkuni processing, ishishini chemical. Oku kusetyenziswa:

• ukuhlanjululwa lwamafutha inclusions sulphur;
• siqala insimbi;
• descaling phambi wire kwalenza, iphepha metal;
• nickel nesingxobo, chromium wazaleka a ebusweni yesinyithi;
• ukuveliswa imithi (umxube becala bakwicandelo organic yokuqaphela);
• imveliso isichumiso (eli candelo liyadla malunga nesiqingatha sulphuric acid kuveliswa kweli lizwe);
• nokuveliswa imicu eyenziweyo;
• imveliso ethyl kotywala ngendlela engeyiyo;
• aveze dayi aniline.

Abantu abanomdla apho ukuthenga sulphuric acid, oko kukhethwa isetyenziswa electrolyte ukuba iibhetri abakhokelayo-asidi.

2. Kwimeko yokusilela lokuyifumana kwakhona ungazama ukwenza kutsha aphele H ₂ SO ₄ electrolyte. Ngoko Ukuxinana liphezulu ayisayi kuba ngaphezu kwe-1.4 g / cm ^3. • Ukuvela komphunga luhlobo lwenziwa ngesitya porcelain kwi bath isanti okanye gypsum. Kuyo nayiphi na imeko, akunakubakho ukwenza le nkqubo ngaphakathi.
3. Khumbula ukuba intengiso kwe-sulphuric acid iphantsi kolawulo, njengoko Le into kusetyenziselwa ukuvelisa iziyobisi, ngokunjalo iziqhushumbisi yasekhaya.
