据我们1985年调查,近几年随着我国化工、医药的蓬勃发展,对搪瓷反应罐的需求剧增,但国内现在还没有合用的化工搪瓷专用板,大多数厂家以A_3作原板。由于涂搪性差,搪烧废品高,成品使用期短(往往仅半年),造成很大浪费。因此,试制出我国良好的化工搪瓷专用板,已是当务之急。化工搪瓷常常在酸碱介质中使用,温度变化在-20～+280℃范围并承受<:6kg/cm_2工作压力,属于低压容器。在制造时要经焊接、冷热成型,因此,在性能上比日用搪瓷有更高和更多的要求,国外,大都采用含钛钢或脱炭钢板(C<0.005％),也有加入镍钼等有利于提高涂搪性的合金。从上所述,化工搪瓷原板,主要要求有良好的涂搪性、成形性,并满足低压容器你化工容器所需
According to our survey in 1985, with the rapid development of chemical industry and medicine in China in recent years, the demand for enamel reaction tank has dramatically increased. However, there is no special chemical enamel plate for domestic use. Most manufacturers use A_3 as original plate. Due to poor coated enamel, high-burning waste products, finished short life expectancy (often only six months), resulting in a great waste. Therefore, trial production of our good chemical enamel special board, it is imperative. Chemical enamel often used in acid-base medium, the temperature changes in the range of -20 ~ +280 ℃ and withstand <: 6kg / cm2 working pressure, belonging to the low pressure vessel. Made by the welding, hot and cold forming, therefore, the performance than the daily enamel have higher and more requirements abroad, most of the use of titanium or carbon off the steel plate (C <0.005%), but also with nickel Molybdenum and other conducive to improve the enamel coated alloy. From the above, the main chemical porcelain enamel plate, the main requirements of good enamel formability, formability and meet the needs of your chemical container low pressure containers
