搪瓷拼装罐由首钢搪瓷专用钢板、密封专用材料、自锁螺栓等材料组装而成，首钢搪瓷专用钢板经过预处理后，在其内外两面涂上二至三层无机玻璃质涂料，经过高温烧结，使涂层和钢板之间形成一种新型复合材料，这种新型复合材料保护层不仅能阻止罐体腐蚀，具有抗酸、碱的功能和很强的抗磨损性。使用寿命长达50年。

The prefabricated glass fused to steel bolted tanks are assembled from special steel plates for enamel coating manufactured by Capital Steel and Iron Company, sealing materials, self-locking bolts, and other materials, After pre-treatment, the special steel plates for enamel coating manufactured by Capital Steel and Iron Company is coated with two to three layers of inorganic glass coating on its inner and outer surfaces. After high-temperature sintering, a new type of composite material is formed between the coating and the steel plate. This new type of composite material protective layer not only prevents tank corrosion, but also has acid and alkali resistance and strong wear resistance.with a service life of up to 50 years.
