一、前言 陕西彩色显像管总厂,从日本引进的彩显管生产线一期工程采用146S热双金属做荫罩温度补偿及框架支撑元件。该材料除要求一定的物理性能和机械性能外。为了保证彩显管的电真空性能,还要求具有较低的放气量。4400厂测定材料的放气量标准条件为: 放气温度:800℃ 放气时间:3分钟 排气速度:4升/秒 在上述条件下,按日本同类材料样品测定的数据,一般认为双金属的放气量Q应在
First, the foreword Shaanxi color picture tube plant, introduced from Japan, the first phase of the color display tube production line using 146S hot bimetal shadow mask temperature compensation and frame support components. In addition to the material requirements of certain physical and mechanical properties. In order to ensure the color vacuum tube electrical vacuum performance, but also requires a lower deflated volume. 4400 factory measured material deflation standard conditions: deflation temperature: 800 ℃ deflation time: 3 minutes Exhaust speed: 4 liters / sec Under the above conditions, according to Japan similar materials sample measured data, generally considered bimetallic Deflation Q should be
