耐火灰浆又称高温灰浆，可用于抵御高温环境。它是一种特殊的砂浆，专为普通砂浆无法承受极端高温的高温应用而设计。耐火砂浆由耐火粉末、粘结剂和外加剂按一定的颗粒比例组成，倒入水或液体粘结剂中制成浆状。耐火泥可制成粉末状，最小粒度可小于 1mm，有的甚至小于 0.5mm。耐火泥具有高密封性能和高耐腐蚀性。根据成分不同，可分为粘土砂浆、高铝砂浆、硅砂浆、镁砂砂浆等。

Clay refractory mortar is made of calcined clay together with raw materials and additives. Clinker is the main component of clay refractory mortar, the content is about 75%~80%. As a joint material, clay refractory mortar can adjust the size deviation of bricks and play an important role in masonry structure.
硅质耐火泥是由硅粉、粘土、外加剂和粘结剂按一定颗粒比例混合而成的耐火泥。硅质砂浆具有耐酸、耐热性高、导热系数低、粘结强度好等优点。硅质耐火泥主要用于砌筑和修补硅砖砌筑的热风炉、焦炉和玻璃窑等工业窑炉。
High alumina mortar is made of high alumina cement and high alumina aggregate, with alumina content over 60%. The refractoriness of high alumina mortar is above 1500℃. High alumina refractory mortar is mixed with water to form a paste for laying and bonding shaped refractory products, such as refractory bricks. Our high alumina refractory mortar is the best choice for high temperature fireplaces, ovens, kilns, furnaces and chimney construction.
1. Metallurgical industry: used to line blast furnaces and ladles, protecting them from extreme high temperatures.
2. Ceramic industry: used to seal and connect kiln components.
3. Power plants: used for boiler repair and maintenance.
