Operation standardization, institutionalization, ensure the accuracy of testing results, unified, effective control of raw materials and product quality.2.适用范围Application适用于型号SS-4GL熔体流动速率仪按GB/T3682-2000的方法测测定热塑性高聚物在高温下熔体流动速率的测定。

Applicable to model SS-4GL melt flow rateinstrument according to the GB / T3682-2000method for determination ofthermoplastic polymer in high temperature melt flow rate measurement.3. 测试前准备Preparation before testing3.1.1 检查工具是否齐全；仪器电源是否接通；棉布是否够用，必须确保有足够的棉布于试验后清洁仪器。

Check whether the tools are prepared completely:instrument power supplyis connected; cotton is enough, must ensure that there is enough cotton to test after the cleaningapparatus.3.1.2 试样准备Sample preparation有关原料及素壳熔融指数的相关实验参数参照《熔融指数试验参数规范表》;On raw materials and grain shell melting index related experimental parameterswith reference to" melt index testing parameter specification table";3.1.3 将素壳剪成约5mm大小颗粒或原料(8g以上) (如图1),进行烘烤.Cut theshell into 5mm particle size or raw materials ( more than 8G ) ( Fig. 1), baking.3.2 测试步骤Testing steps3.2.1 启动仪器及程序设定Starting apparatus and program将活塞杆及口模放入料筒中，接上电源并按电源键启动仪器(如图2)，程序中设定条件和参数随塑胶种类的不同而需作相应的设定，设定方法如下：Put thepiston rod and the die into the barrel, switch on and press the power button tostart apparatus ( Figure 2), procedures set of conditions and parameters with theplastic different types require the corresponding set, setting method as follows: 按菜单试验参数设定(如图3) 依次输入要求加热温度值，Press menu testparameter setting (Figure 3) input required temperature value，for example：260℃press“260”to confirm；（温度要求参照《熔融指数试验参数规范表》和相关物性表），预热时Made/Date Operating rules of G OTTFERTR熔融指数仪操作规程Doc.
