我国自行研制成功的一项填补国内空白的涂装设备——无机锌和环氧富锌涂料专用无气喷涂机,已于1990年5月27日通过部级鉴定。性能优良的无机锌和环氧富锌涂料,属重防腐蚀涂料。特别是无机锌涂料,有优异的耐候性和耐磨性,以及优良的耐化学性能、耐酸、耐油和耐溶剂性能,并可耐约400℃左右的高温。该涂料中由于锌粉含量高,具有良好的阴极保护作用,因而适于在海洋和工业环境中服役的钢结构件。但这种涂料粘稠度极大,对喷涂机高压缸磨损厉害,且喷涂时极易发生沉淀及结块现象,需要一种专用喷涂设备方能施工。为此,机械电子工业部将这种专用设备列为“七五”重大技术装备科技攻关项目,由中国船舶工业总
China successfully developed a domestic painting equipment to fill the gap - inorganic zinc and zinc-free epoxy coating for airless spray machine, has been in May 27, 1990 through ministerial identification. Excellent performance of inorganic zinc and epoxy zinc-rich paint, is a heavy anti-corrosion coatings. In particular, inorganic zinc coating, has excellent weatherability and abrasion resistance, and excellent chemical resistance, acid, oil and solvent resistance, and resistant to about 400 ℃ high temperature. Due to its high zinc content and good cathodic protection, the coating is suitable for steel structures that serve in marine and industrial environments. However, this coating viscosity is very great, high pressure cylinder sprayer terrible wear, and prone to precipitation precipitation and caking phenomenon, the need for a special spraying equipment before construction. To this end, the Ministry of Machinery and Electronic Industry will be such a special equipment as a “Seventh Five-Year” major technical equipment scientific and technological projects, by the China National Shipbuilding Industry
