Dolomite lining composite material and preparation method thereof
The invention discloses a preparation method of a dolomite lining composite material. The preparation method comprises the following steps: preparing a proper amount of dolomite, talcum powder, zinc stearate and sodium silicate; the preparation method comprises the following steps: crushing weighed dolomite, filtering and screening to obtain dolomite powder, putting the dolomite powder into kneading machine equipment, adding talcum powder and zinc stearate in proportion, and mixing and stirring to obtain dolomite composite powder; the dolomite powder and sodium silicate are put into a kneading machine according to the proportion to be mixed, stirred and dried, and final dolomite composite powder is obtained; and finally, pressing into a dolomite lining blank body through a four-column hydraulic press, and drying. On the basis of not influencing the heat preservation and pressure transmission performance of the dolomite lining, the talcum powder and the zinc stearate are used for replacing graphite, so that the mold release property is good; meanwhile, compared with graphite, the talcum powder has a smaller heat conductivity coefficient (0.25 w/(m.k)), so that better heat preservation and heat insulation can be realized, the current fluctuation during synthesis is effectively reduced, the quality and efficiency of diamond synthesis are improved, the productivity is increased, the hammer consumption is reduced, and the advantages of energy conservation and synergistic production are realized.
本发明公开了一种白云石内衬复合材料的制备方法：准备适量白云石、滑石粉、硬脂酸锌和硅酸钠；称取的白云石进行破碎，并过滤筛分，得到白云石粉置入到捏合机设备中，按比例加入滑石粉和硬脂酸锌进行混合搅拌，得到白云石复合粉料；再和硅酸钠按比例置入捏合机中进行混合搅拌并烘干得到最终的白云石复合粉料；最后通过四柱液压机压制成白云石内衬胚体并烘干。本发明在不影响白云石内衬保温传压性能的基础上，利用滑石粉和硬脂酸锌来代替石墨，具有良好的脱模性，同时滑石粉相比于石墨具备较小的导热系数（0.25w/(m·k)，能实现更好的保温隔热，有效降低合成时电流波动，提高合成钻石的质量和效率，增加了产能，降低了锤耗，实现了节能、增效生产的优点。
