Astaamaha warbaahinta kaladuwan iyo sharraxaadda qalabka ku habboon

Waa dhexdhexaad oksidid ah. HNO3 caadi ahaan waxay ka shaqeysaa heerkulka ka hooseeya 40 ° C. Elements such as chromium (Cr) and silicon (Si) are resistant to oxidation, making stainless steel and other materials containing Cr and Si ideal for resisting corrosion from concentrated HNO3.

Chromium sare chromium cron (CR28):
Steel aan bir lahayn (Sus304, Sus316, Sus316l):


Aluminium saafi ah oo saafi ah (Al):Ku habboon dhammaan heerkulka heerkulka qolka (oo loogu isticmaalo weelasha kaliya).

Sababo la xiriira iska caabbinta qaaska ah, agabyada sida macnaha, degenaanshaha c, dahabka, iyo tuntalom sidoo kale way ku habboon yihiin.

The boiling point increases with the concentration. For example, at a concentration of 5%, the boiling point is 101°C; at 50% concentration, it is 124°C; and at 98% concentration, it is 332°C. Ka hooseeya 75% feejignaanta, waxay soo bandhigtay yareynta guryaha (ama dhexdhexaad ah), iyo ka sareeya 75%, waxay soo bandhigtay guryaha otomaatiga ah.
Star Stainsens (Sus316, Sus316l):

Uruurinta kala duwan ee u dhexeeya heerkulka qolka iyo 90 ° C.
Sunta rasaasta saafiga ah, hogaan adag:
Aashitadu waxay ka kooban tahay 90 ° C, heerkulka sare waxay uruurinta aashitada sulfuric acid (120 ~ 150 ° C).
Kaararka kaarboon ee caadiga ah:Aashitada sulfuric acid ka sarreeya 70% heerkulka qolka.
Bir bir ah:
Monel, birta Nikkel, oo ay ku jiraan:Heerkulka dhexdhexaadka ah iyo feejignaanta dhexdhexaadka ah ee sulfuric acid.
Titanium Molybdeum Alloy (TI-32mo):Ka hooseeya barta karkaraya, 60% sulfuric acid; ka hooseeya 50 ° C, 98% sulfuric acid.


60 ~ 90% sulfuric acid heerkulka qolka.

Acid hydrochloric acid (hcl)

Waa sheyga ugu habboon ee ugu habboon ee loo yaqaan 'cheasion-ugu adkaysiga' hydrochloric acid ', laakiin waa qaali waxaana badanaa loo isticmaalaa aaladaha saxda ah ee cabirka.
Ku habboon hydrochloric acid Heerkulka ≤ 50 ° C iyo uruurinta illaa 36%.
Titanium-molybdenum alfoy (ti-32mo):
Nickel-molybdenum alkoy (chlorimet, 0ni62mo32Fe3):
Ganacsig saafi ah oo saafi ah (TA1, TA2):Ku habboon hydrochloric acid heerkulka qolka iyo uruurinta ka hooseeya 10%.

Acid Phosphoric (H3PO4)

Star Stainsens (Sus316, Sus316l):Ku habboon in lagu kariyo maadada phosphoric acid-ka salka ku haysa ee ka hooseeya 85%.
Durunet 20 (aleonad 20):
CD-4MCU:


Oo macbudka 825:

Acid hydrofluric acid waa sun aad u sarreeya. Birta sare ee silicon, dhoobada, iyo dhalada ayaa guud ahaan u adkaysata aashitada badankood, laakiin hydrofluoric acid ayaa xami kara.

Isugeynta ka hooseysa 40%, heerkulka ka hooseeya 100 ° C.

0cr13, 1cr13, 1cr17.
