Kumene kugula asidi sulfuric? Anasankha malonda ndi malangizo

Osati zipangizo zonse ndi reagents tsopano mu ufulu ritelo. Chimodzi mwa zinthu zimenezi ndi zovuta sulfuric acid. Tikambirana chiyani m'nkhani ino, zimene zimaphatikizapo ndi kumene zikhoza kugulidwa m'mizinda Russian.

chidulo cha safuriki - ndi ... Transport, yosungirako

Ndikudabwa kumene mukhoza kugula chidulo cha safuriki, timakumbukira woyamba za katundu wa yoopsa anthu. chidulo cha safuriki ndi mtundu wa asidi amphamvu dibasic, chilinganizo ake - H _{2 4.} Mu Russia, osakaniza uyu wa trioxide sulfure ndi madzi opangidwa malinga GOST 667-73, 2184-77, 4240-77. Kupanga madzi katundu wochuluka yomwe alibe mtundu uliwonse kapena fungo, pali mitundu ingapo, amene amasiyana chiyero chawo ndi ndende.

chidulo cha safuriki ali zotsatirazi katundu zofunika:

• Specific Timizereto - 1,85 g / masentimita ³ (mu abwino asidi mtheradi sulfuric - 1,92 g / masentimita ^3, koma mankhwala ali ndi chidwi drawback - atapanga pa madigiri -10 centigrade).
• Otentha mfundo - +296,5 ^° centigrade, ndi crystallization mfundo - + 10,45 ° Celsius.
• Pa woipa 70% pa Kutentha ndi kuwira kwa asidi izi zigwire madzi nthunzi. Pa nkhani apamwamba a H _{2 4} mu mlengalenga ndi kugwa zoipa asidi excretion.
• Zachiwawa ndi flammable mankhwala. Pa kukhudzana ndi madzi woyenera kuopedwa anachita ziwawa, chifukwa mu mpweya kusanduka, nthunzi, kutentha. Ichi ndi chifukwa chake ntchito ndi asidi sulfuric m'pofunika kukhala zobvala zapadera, nsapato ya munthu mankhwala chitetezo.

Kwa mapeto wosuta sulfuric asidi onse msewu ndi zoyendera njanji. Yogwiritsira ntchito muli wapadera asidi sulfuric (kwa asidi luso sulfuric) kapena asidi zosagwira thanki (kwa bwino H _{2 4).}

Pa yosungirako M'pofunikanso kukumbukira kuti chidulo sulfuric - chinthu poizoni a m'kalasi yachiwiri ya ngozi. The pazipita otetezeka ndende ya nthunzi H _{2 4} - 1 mg / mamita ^3. Musanayambe kusankha kumene kugula asidi sulfuric (luso), muyenera kugula muli wapadera yosungirako. Kumanga kupanga ake anapitiriza obkladyvayut asidi zosagwira njerwa.

The ntchito asidi sulfuric

The ogula chachikulu cha asidi sulfuric - yopangira zitsulo, zomera nkhuni processing, makampani mankhwala. Amagwiritsidwa ntchito:

• kuyeretsa mafuta inclusions sulfure;
• miyalayo kuwonongeka;
• descaling pamaso waya kanasonkhezereka, pepala zitsulo;
• faifi tambala plating, chromium plating zitsulo pamwamba;
• kupanga asatayike (anaikira yothetsera mu kaphatikizidwe organic);
• Feteleza kupanga (gawo ili amadya pafupifupi theka la chidulo sulfuric opangidwa ku dziko);
• kupanga ulusi yokumba;
• kupanga ethyl mowa;
• wobala ndi aniline utoto.

Anthu amene ali ndi chidwi kumene kugula chidulo cha safuriki, ndi makamaka ntchito ngati electrolyte chifukwa mabatire kutsogolera-acid.

Kumene kugula asidi sulfuric

The mankhwala sulfuric asidi musati kugulitsa konse. Munthu kuti akhale ake njira sanali kuikapo maganizo (30-35%) mu masitolo, pozindikira mbali magalimoto ndi mankhwala magalimoto. Wambiri njira - n'zofanana kwa anthu amene mwalamulo ali kugulisa.

Amene achita chinthu kupeza yoteroyo patsogolo kudziwa kumene kugula chidulo cha safuriki, kupereka malangizo anthu.

Nsonga Kugula

Choncho, nkofunika kukumbukira zotsatirazi:

1. Munthu payekha, mu nthawi zina, anagulitsa wambirimbiri mankhwala - ayenera pang'onopang'ono kupeza, kwa ogulitsa zosiyanasiyana.
2. Mu nkhani ya kulephera kwa kupeza akhoza kuyesetsa vaporize H _{2 4} electrolyte. The kachulukidwe pazipita Choncho sadzakhala oposa 1.4 g / masentimita ^3. Evaporation ikuchitika mu zadothi chotengera pa mchenga osamba kapena gypsum. Mulimonsemo sikutheka kuti ndondomeko imeneyi m'nyumba.
3. Kumbukirani kuti kugulitsa asidi sulfuric lolamulidwa, monga mankhwala ntchito kubala mankhwala, komanso mabomba kunyumba zopangidwa. Ngakhale ngati inu mukumvetsa izo mayesero osalakwa kapena refilling avtoakkumulyatora zedi si yaing'ono, zingayambitse kukayikirana zosafunika.

Ndingapite kugula asidi sulfuric mu Moscow

Mu likulu kugula asidi sulfuric akhoza kukhala:

• "Himmede";
• "Sigma-Tek";
• Intaneti sitolo JSC "KhimServis";
• Ltd. "The chigawo-reagent";
• "Odiham" LLC;
• LLC "Mega-mankhwala" (luso, rechargeable, mankhwala koyera) - kampani sachiza ndi amalonda payekha.
