Description

10 15 20 25 30 447 914 2 Exempel Koncentration av Procentuellt korro- aluminium-g1ukon- sionsskydd för 1010- syrakomplex stålprovbitar l Nollprov (ingen be- handling) 00 2 3,1! ppm 117,7% 3 6,8 ppm 76,1 H 6,8 ppm 73,0 5 6,8 ppm -75,0 6 10,2 ppm 73,0 Vid behandling av ett vattenbaserat system i enlighet med' sättet enligt föreliggande uppfinning upprätthålles ca 0,1 - 500 ppm av inhibitorkomplexet i vattnet, ännu hellre 1-50 ppm.
Denna inhibitor kan blandas med vilka som helst välkända skalningsinhibitorer, dispergeringsmedel och gulmetallkorro- sionsinhibitorer, såsom bensotriazol eller merkaptobensotiazol.
Bland typiska industriella tillämpningar där föreliggande uppfin- ning är användbar kan nämnas behandling av vatten, strâlnings- kylmedel, hydraulisktfluidum, anti-frysmedium, värmeöverförings- medium och petroleumkällor.
Glukonater är välkända i samband med behandling av vatten.
I USPS 3 095 862 beskrivs användning av kalciumglukonat i syfte att eliminera karbonat. I USPS 3 711 ZH6 beskrivs användning av natriumglukonat tillsammans med natriumsilikat i syfte att reg- lera oxidativ korrosion. 'USPS H 108 790 omtalar användning av natrium- och ammmfiuglukonater för oxidativ reglering i kylvat- tensystem. I USPS H 120 655 avslöjas användning av en fosfor- syraester plus ett glukonat av en metall ur grupperna II till VIII i det periodiska systemet för reglering av ferrokorrosion.
Föreliggande uppfinning representerar emellertid, såvitt vi vet, för första gången användning av det häri beskrivna komplexet av AlCl5 . 6H2O/glukonsyra som enda effektiva korrosionsreglerande tillsatsmedel för järn- och stålytor.
