Superfine ceramic fiber cotton and production method thereof
The invention discloses superfine ceramic fiber cotton and a production method thereof. The superfine ceramic fiber cotton comprises the following raw materials in parts by weight: 30-40 parts of clay clinker, 40-48 parts of alumina powder, 10-18 parts of silica sol, 12-20 parts of chromic oxide, 6-14 parts of magnesium chloride, 5-9 parts of a binding agent, 8-18 parts of a thickening agent and 3-5 parts of a refractory agent. Specifically, the superfine ceramic fiber cotton comprises the following raw materials in parts by weight: 30 parts of the clay clinker, 40 parts of the alumina powder, 10 parts of the silica sol, 12 parts of the chromic oxide, 6 parts of the magnesium chloride, 5 parts of the binding agent, 8 parts of the thickening agent and 3 parts of the refractory agent. According to the invention, chromium oxide is added into the preparation raw materials, high-temperature melting is performed, and then fusion is conducted, so the use temperature of ceramic fibers can be further increased; and the binding agent and the thickening agent are added in a wire drawing method, fibers with different diameters can be obtained by adjusting viscosity, the diameter of a bushing hole and a wire drawing speed, so the situation that the thickness of a formed cotton blank is not uniform is avoided.
本发明公开了一种超细陶瓷纤维棉及其生产方法，包括以下重量份原料：黏土熟料30‑40份、氧化铝粉40‑48份、硅溶胶10‑18份、氧化铬12‑20份、氯化镁6‑14份、结合剂5‑9份、增稠剂8‑18份和耐火剂3‑5份，包括以下重量份原料：黏土熟料30份、氧化铝粉40份、硅溶胶10份、氧化铬12份、氯化镁6份、结合剂5份、增稠剂8份和耐火剂3份。本发明通过在制备原料中加入了氧化铬，再经过高温融化后进行融合，可以使陶瓷纤维的使用温度进一步提高，本发明中使用拉丝法中加入结合剂和增稠剂，可以通过调整黏度、漏板孔的直径和拉丝速度可获得不同直径的纤维，避免形成的棉坯出现厚度不均匀的情况。
