this standard specifies two methods: method A and method B.It is measured by measuring the flow time of powder or granular plastic out of the funnel.Method A can obtains information related to processing performance, while method B is designed for process control during production, PVC resin
Indicate by the needed time which a certain mass or volume of sample outflow the prescribed dimensions funnel.
四.参数资料
漏斗:漏斗带有可转换接口,不锈钢材质,内壁抛光处理;漏斗出口带控制阀门,漏斗配置接地线.
Funnel: funnel with convertible interface, stainless steel, inner wall with polishing treatment. Funnel outlet with control valve, Funnel has grounding wire to eliminate the impact of static electricity on the test results.
The upper opening diameter of the funnel: 110mm. The outlet diameter respectively: 10±0.05mm,height: 140mm. 15±0.05mm,height: 133mm. 25±0.05mm,height:120mm in three specifications. Angle is 40 degrees. According to the standard requirements if the liquidity of the test sample is poor, unable to flow completely or not at all, therefore the diameter of funnel is changed in test, and indicated in the test report.
五.本仪器配置试验支架用于支持漏斗的稳定性
This instrument is equipped with bracket which use for support the stability of funnel.
