1 Scope

YS/T 581 This part specifies the method for measuring the liquidity of aluminum fluoride. This section applies to the determination of the inherent liquidity aluminum fluoride through a special funnel.

2 principle of the method

A certain quality of aluminum fluoride through a special funnel, funnel flow time measurement sample all you want. Liquidity to flow when required Room to represent.

3 instruments and devices

3.1 Instrument. usually manual or automatic measuring device measurement, automatic measurement apparatus shown in Figure 1. 3.2 Funnel. Exact making a stainless steel funnel (Fig. 2), the apparatus outlet diameter of 3.95mm ~ 4.00mm wear resistant stainless steel. The diameter shall be calibrated. The funnel needed to use dry and clean, otherwise the flow of time can not be repeated. 3.3 Timer. Stop watch or other automated means to accurately 0.1s. 3.4 Balance. a sense of the amount of 0.1g. 3.5 Test sieve. sieve 500μm, for removing large particle size.

1 Automatic flow time measurement device

4 Sample Preparation

4.1 The sample is placed in a tray, tile thickness of not more than 5mm, the balance in the test chamber atmosphere 2h. 4.2 The sample was equilibrated by the test sieve (3.5) to remove large particles, the lower part of the screen the sample into three parts, each part about 105g ~ 120g, each for measuring times. ......
