陶瓷管道弯管处涂抹陶瓷颗粒胶

在管路系统中,弯头是改变管路方向的管件。按角度分,有45°及90°180°三种最常用的,另外根据工程需要还包括60°等其他非正常角度弯头。弯头的材料有铸铁、不锈钢、合金钢、可锻铸铁、碳钢、有色金属及塑料等。与管子连接的方式有:直接焊接(最常用的方式)法兰连接、热熔连接、电熔连接、螺纹连接及承插式连接等。由于弯头具有良好的综合性能,所以它广泛用于化工、建筑、给水、排水、石油、轻重工业、冷冻、卫生、水暖、消防、电力、航天、造船等基础工程。
通常物料通过管道弯头时,由于离心力和惯性撞向管道外侧的内壁。一部分颗粒沿着管壁外侧的内壁滑动;另一部分颗粒又从外侧内壁反射到管道内侧的内壁,如此反复运动;物料经过数次碰撞,在圆断面弯头的外壁中部,会产生像用凿凿出的凹坑,弯头表面是由于粒子的摩擦引起的表面磨薄,同时是由于粒子的撞击使表面的组织产生局部的破碎和脱离。对于担负着电力、冶金、煤炭、石油、化工、建材、机械等行业输送介质的管道弯头,长期受介质冲刷磨损、腐蚀、高温氧化等过度消耗而极易失效。由此产生介质跑、冒、滴、漏的现象,这不单引起能源和金属材料消耗增加而造成的经济损失,而且对环境的污染也是非常大的。由此,对管道弯头材料磨损和耐磨材料的研究,越来越引起国内外人们的广泛重视。
我公司选用优质氧化锆陶瓷颗粒胶涂抹于陶瓷贴片管道弯头内侧在神华煤化工项目上取得了良好的进展,为此我公司获得了2014年建材新产品金奖,欢迎选用陶瓷颗粒胶比高铬铸铁还要耐磨损。

Silicon carbide alloy ceramic wear tube

Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher. Both forms of silicon carbide (SiC) are highly wear resistant with good mechanical properties, including high temperature strength and thermal shock resistance. Our engineers are always available to best advise you on the strengths and weaknesses of ea...
