发明名称 Vinyl sulfonic acid - methacrylic acid copolymer passivators for high pressure boilers
摘要 Certain polymers of vinylsulfonic and methacrylic acid promote the formation of passive, protective oxide films on steel surfaces under alkaline boiler conditions and at high pressures e.g. pH 11 1,000 to 1,500 psi, while giving good control of mineral deposition in the boiler.
