標(biāo)準(zhǔn):

GB/T-6609.31-2009 Chemical analysis methods and determination of physical performance of alumina - Part 31: Determination of angle of flo

standard:

GB/T-6609.31-2009 Chemical analysis methods and determination of physical performance of alumina-Part 31: Determination of angle of flo

 適用范圍:

本部分適用于氧化鋁流動(dòng)角測(cè)定，測(cè)定范圍：30°-50°.

Scope of application:

This part is applicable to the determination of alumina flow angle, the measurement range: 30°-50°.

流動(dòng)角：

試料在測(cè)試瓶中停止流動(dòng)后，試料形成的椎形面與測(cè)試瓶底間形成的角度。

Flow angle:

The angle formed between the conical surface formed by the sample and the bottom of the test bottle after the sample stops flowing in the test bottle.

原理：

將氧化鋁通過一系列漏斗倒入平底容器中。允許通過漏口下漏的氧化鋁流出平底容器，根據(jù)用于填充容器的試料質(zhì)量和試驗(yàn)后容器內(nèi)存在試料的質(zhì)量計(jì)算流動(dòng)角度.

principle:

Pour the alumina through a series of funnels into a flat-bottomed container. Allow the alumina leaking through the leak to flow out of the flat-bottomed container, and calculate the flow angle based on the mass of the sample used to fill the container and the mass of the sample in the container after the test.
