Formula, production process and method of environment-friendly refractory material
The invention discloses a formula, a production process and a method of an environment-friendly refractory material, and belongs to the technical field of refractory materials, the formula of the environment-friendly refractory material comprises the following components in equal parts by mass: 30-40 parts of a magnesium blank, 2-4 parts of lime milk, 30-40 parts of a binding agent, 8-10 parts of water and 30-40 parts of chromium sesquioxide. The magnesium blank comprises 45-55 parts of magnesite, 45-55 parts of seawater magnesia and 5-15 parts of dolomite; the catalyst also comprises sodium hydroxide and a manganese dioxide and oxalic acid mixture; after the raw materials are fully mixed and stirred, the surface of the material can be covered with a layer of chromic oxide particles, the fire resistance of the material can be greatly improved, the material can bear a higher-temperature working environment, sodium hydroxide is added in the mixing and stirring process, the sodium hydroxide can be hydrolyzed into hydroxyl ions and sodium ions when meeting water, and the heat resistance of the material is improved. Sulfur ions in reaction raw materials can be absorbed through sodium ions, emission of sulfur dioxide waste gas in the production process can be effectively reduced, and therefore the environment-friendly effect is achieved.
本发明公开了一种环保型耐火材料的配方、生产工艺及方法，属于耐火材料技术领域，一种环保型耐火材料的配方，耐火材料按照等份质量的组成成分包括：镁质胚料30‑40份、石灰乳2‑4份、结合剂30‑40份、水8‑10份、三氧化二铬30‑40份，镁质胚料包括菱镁矿45‑55份、海水镁砂45‑55份、白云石5‑15份；还包括氢氧化钠和二氧化锰与草酸混合物；通过将原料充分混合搅拌后，材料表面会覆盖一层三氧化二铬颗粒，能够极大的提高材料的耐火性，使其能够承受更高温度的工作环境，在混合搅拌过程中，通过加入氢氧化钠，氢氧化钠遇水会水解成氢氧根离子和钠离子，可通过钠离子吸收反应原料中的硫离子,可以有效的减少生产过程中二氧化硫废气的排放，从而达到环保效果。
