搪瓷管的工作温度对自身使用的影响

为了能让大家更多的了解搪瓷管，下面给大家介绍搪瓷管的工作温度对自身使用的影响：

in order to let you know more about enamel pipe， the following to ioduce the work temperature of enamel pipe for their use:

搪瓷管经900℃高温焙烧，冷却后搪瓷与钢板粘结在一起。由于搪瓷的线膨胀系数和延伸率小于钢板，因此冷却后搪玻璃的变形量小于钢板的变形量，搪瓷受到钢板的约束产生压应力。搪瓷管制成后，其搪玻璃即存在预压缩应力，而钢板则存在预拉伸应力。

enamel tubes were calcined at high temperature after 900，&the cooling was bonded with the steel plate. because the enamel linear expansion coefficient&extension rate is less than the steel， so cooling after deformation of the glass lined smaller than that of the plate deformation， enamel is compressive stress caused by plate ctraint. after the cool of enamel， glass lining is pre compressive stress，&the steel plate are pre tensile stress.

由于预应力与线膨胀系数和延伸率相关，线膨胀系数和延伸率与温度又密切相关，因此搪瓷管的工作温度对搪瓷管的使用影响很大。如果因温度变化大而使搪瓷产生的应力超过其使用应力，搪瓷将被破坏。

as the prestressing force is related to linear expansion coefficient&elongation coefficient， linear expansion coefficient&extension rate are closely related to the temperature. enamel will be destroyed if the temperature changes greatly&the stress of the enamel is more than that of its use.

因此搪瓷管搪瓷层遇冷、热急变，极瓷。因此搪瓷管有耐温---：温度 200℃，耐温急变：冷冲击<1io~c，热冲击<120℃。投料时物料温度与罐体温差太大以及升温时蒸汽过猛、降温太急也能导致爆瓷。因此搪瓷管在使用中升、降温要缓慢、均匀，分级冷却。

therefore， the enamel enamel pipe cold hot blast， highly explosive porcelain. the enamel pipe with temperature resistant limit: 200 degrees celsius temperature，搪瓷管空气预热器厂家， high temperature blast: cold shock <1io~c， heat shock <120 c. the temperature of the material&the tank temperature difference of the feed is too high&the heating steam， excessive cooling too quickly can also lead to explosive porcelain. therefore， in the use of enamel pipe/slow cooling， uniform cooling， grading.
