建筑用浇注料#耐火浇注料@新一代耐火浇注料^高质量浇注料
浇注料是一种由耐火物质制成的粒状和粉状材料,并加入一定量结合剂和水分共同组成。它具有较高的流动性,适宜用浇注方法施工,并无需加热即可硬化的不定形耐火材料。由耐火骨料、粉料、结合剂、外加剂、水或其他液体材料组成。一般在使用现场以浇注、震动或捣固的方法浇筑成型,也可以制成预制件使用。
耐火浇注料是不定形耐火材料的主要品种,在第二次*时期美国以耐火浇注料作为锅炉或石油生产设备的异型砖代用品使用,日本于1950年开始研究生产此类材料。20世纪50年代初期,苏联开始应用硅酸盐水泥耐火浇注料。60年代以来,不定形耐火材料发展迅速,到90年代日、美、德等*的不定形耐火材料产量已占耐火材料总产量的1/3以上,而耐火浇注料占不定形耐火材料的40%~50%。中国在20世纪50年代初期开始应用硅酸盐水泥耐火浇注料,当时称为耐热混凝土,主要用于%26rsquo;700℃以下(有时700~1200℃)的热工构筑物,1965~1975年普遍采用铝酸钙水泥和****盐耐火浇注料,当时称为耐火混凝土,使用温度****到1400~1600℃,在此期间建设了产品生产基地,1976年初建立了产品标准,1976年以后,产品种类迅速增加,质量也逐步****,80年代中期中国又开发了新一代耐火浇注料,包括低水泥、超低水泥和无水泥耐火浇注料,其质量接近国际****水平。产品展示-*耐火浇注料系列 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
