Description

一种具有保温材料的铂金通道及其使用方法
技术领域
本发明属于玻璃生产技术领域，具体地，涉及一种具有保温材料的铂金 通道及其使用方法。
背景技术
高端玻璃熔制过程中，需要将玻璃熔体中的物理溶解气体和混在玻璃体 中的微小气泡全部排出玻璃熔体外，得到高质量的玻璃，此过程为玻璃的澄 清。现有技术一般均设置铂金通道，玻璃澄清方法，通过高温降低玻璃液粘 度加速气体排出，同时配合澄清剂释放气体加速排泡。由于加热段、澄清段 和搅拌段需要保持或升高玻璃液的温度，因此通常该区段需要做厚厚的保温 材料，以减少散热，否则就需要配合大功率加热设备。
常用铂金通道需要配合合适的环境气氛使用，以减少铂金挥发和减少玻 璃液气泡。一般是氮气为主的高湿环境气氛。一般的做法是在铂金通道外部 建设一个恒温恒湿房间，在房间内通入氮气和水汽，或者在铂金通道本体外 部做一个密闭罩，在罩内通入氮气和水汽。
现有技术中以增加保温材料为手段，则需要将铂金整体做的非常庞大， 增加材料用量和成本，同时大量的使用保温材料会使得设备庞大，占地面积 和空间占用提高，增加了设备维护难度。由于重量的增加导致底部材料抗压 性能需相应提高。且保温层厚度达到一定极限以后，再增加厚度对保温性能 影响变得非常微弱。若以增加加热功率为手段，则需要一系列供电设备增加 功率，增加导电铜排的使用量，不仅增加一次费用，而且安装和运行成本提 高；作为环境气氛的房间或者是密闭罩，除制造困难外，由于隔离的人员与 设备，对设备点检和维护造成了较大的困难。

步骤S2、将基底粉体和莫来石混合均匀，莫来石的用量为基底粉体重量 的10％，球磨、过筛，烘干，制得增强料，之后加入刚玉、镁铝尖晶石和铝 矾土，混合均匀后在1500℃下煅烧1h，冷却后粉碎研磨，滚球，制成空心微 球，之后将制成的空心微球和细粉通过粘结剂制成空心砖坯体，在1500℃下 煅烧1h，制得空心砖，控制刚玉、镁铝尖晶石和铝矾土的重量比为1∶2∶3， 刚玉、镁铝尖晶石和铝矾土的重量和为增强料重量的20％，空心微球、细粉和粘结剂的重量比为10∶1-2∶0.3-0.5。
进一步地，复合保温层为莫来石和氧化锆按照5∶1的重量比混合制成。
一种具有保温材料的铂金通道的使用方法，包括如下步骤：
首先在铂金通道本体外表面通过电弧喷涂技术喷涂氧化锆干粉形成涂层， 之后在铂金通道本体两端安装法兰，之后将莫来石层安装在铂金通道本体表 面的涂层外侧，莫来石层外表面安装保温隔热砖层，保温隔热砖层外表面安 装复合保温层，莫来石层、保温隔热砖层和复合保温层形成耐火保温材料层， 之后在复合保温层外侧安装内层玻璃，内层玻璃和外层玻璃之间两侧端部安 装端部密封料，形成密闭空间，内层玻璃和外层玻璃之间安装若干个弧形支 撑，抽真空，内层玻璃和外层玻璃之间的密闭空间形成真空空间，在内层玻 璃和外层玻璃的表面镀银。

而且本发明减小了设备体积和材料用量，能够降低供电设备的功率， 减少运行费用，使用最小化的密闭罩作为环境气氛隔离间，最大程度的降 低了气氛隔离带来的不便，提高维护工作效率。
