Potaziyamu dichromate - katundu physicochemical ndi munda wa ntchito

Potaziyamu dichromate ndi makamaka sanali caking lalanje makhiristo (nthawizina utoto) amene ali mosavuta sungunuka amadzimadzi sing'anga ndi kumaoneka ngati masingano ndi wochenjera kapena mbale. Pamene zimavuta ndi thunthu amadzimadzi njira amakhala acidic.

Potaziyamu dichromate - kwambiri poizoni, carcinogen ndi oxidants amphamvu. Utsi njira angathe kuwononga khungu, chichereŵechereŵe, ndi inhalation ya nthunzi - Airways.

Pa kutentha pafupifupi 1300 ° C chifukwa cha kuwombola zimene dichromate soda ndi mankhwala enaake potaziyamu zakonzedwa dichromate potassium amene chilinganizo K ₂ Kr ₂ O _7:

2KCl + Na ₂ Kr ₂ O ₇ → K ₂ Kr ₂ O ₇ + 2NaCl.

mankhwala ntchito mu makampani. Luso bichromate potaziyamu ntchito yopanga machesi mabatire youma, inki zochita kupanga, zokutira utoto komanso kaphatikizidwe organic - kulandira mitundu yosiyanasiyana ya mankhwala.

Red-chikasu njira ya potaziyamu dichromate banga litmus wotumbululuka mtundu wofiira. Pa Reflux zina mankhwala njira amakhala ndi khalidwe mdima yofiira mtundu. Pamene kutentha anafika 398 ^Inu C potaziyamu dichromate chimasungunula ndipo inasanduka madzi woderapo mtundu, amene pa solidifies wotsatira kuzirala ndi crystallizes. Pamwamba 500 ^Inu C mankhwala kwathunthu linakwiriridwa kuti mpweya mapangidwe, okusayidi chromium ndi chromate potaziyamu.

Physicochemical katundu wa dichromate potaziyamu

Yosungirako ndi zoyendera wa zinthu mankhwala kalasi mkulu ngozi

Luso dichromate potaziyamu akhoza kusamutsidwa ndi zoyendera iliyonse yokutidwa, kupatula mpweya. Chemical, odzaza mu muli wapadera anafuna kuti ntchito kamodzi, inu angaphunzitse lotseguka sitima anagubuduza katundu. Luso dichromate potaziyamu ayenera kusungidwa mu maofesi youma yosungirako, pamene mankhwala mu muli apadera kopita umodzi akhoza kusungidwa panja, okonzeka ndi ❖ kuyanika zolimba runoff madzi.

Kenaka mankhwala kuti a kalasi yoyamba ya ngozi

Luso dichromate potaziyamu mmatumba mu ng'oma mwapadera zitsulo komanso mapepala apulasitiki, wopangidwa mwa zigawo zisanu, masekeli makilogalamu 50. Analola ankanyamula mu muli zofewa, cholinga chapadera ntchito limodzi.

Atathana gulu la ngozi zamankhwala

Luso potaziyamu dichromate kuphulika ndi ngozi moto. Mlingo wa chikoka pa thupi la munthu kuti kalasi yoyamba ngozi akapatsidwa. Pamene tikugwira ntchito ndi mankhwala ziyenela kuyan'anidwa chitetezo kusamala kwambiri ndi tcheru ndipo lingagwiritsidwe PPE khungu ndi ziwalo kupuma.
