为了寻求一种经济适用、机械性能较好、温度适应范围较大(42~一35℃左右)、防锈期较长(两年以上)以及包装要求简单的封存防锈材料和方法,我们进行了硬膜防护涂层的试验工作,并取得了初步的效果。一、涂料的选用及配制1.内层配方:NaNO_2 15%硅酸钠(模数2.4) 2%NaOH 1~2%水(软水) 余量制备:先将硅酸钠加入水中,加热到90℃左右时加入 NaNO_2,停止加热,溶完
In order to find a suitable economical and mechanical properties, the larger the temperature range (42 ~ 35 ℃), anti-rust longer (more than two years) and the packaging requirements of simple rust-proof materials and methods, we proceed The dura protective coating test work, and achieved initial results. First, the choice of paint and preparation 1. Inner formula: NaNO_2 15% sodium silicate (modulus 2.4) 2% NaOH 1 ~ 2% water (soft water) margin Preparation: First sodium silicate into the water, heated to 90 When adding about NaNO_2, stop heating and dissolve
