粒状木质纤维松方密度试验仪用于测量粒状木质纤维的松方密度，全金属结构，金属杯容积为10ml,结构简单，使用方便，可随身携带，手持测量。

The granular wood fiber bulk density tester is used to measure the bulk density of granular wood fibers. It has an all-metal structure and a metal cup with a volume of 10ml. It has a simple structure and is easy to use. It can be carried around and measured by hand.

粒状木质纤维松方密度试验仪技术参数：

◆金属杯容积：100ml φ40*80

◆漏斗直径：55mm/35mm

◆漏斗高度：115mm ；　

Technical parameters of granular wood fiber loose square density tester:

◆Volume of metal cup: 100ml φ40*80

◆Funnel diameter: 55mm/35mm

◆Funnel height: 115mm;

粒状木质纤维松方密度试验仪使用方法：

◆按四分法取2份100g±1g 纤维试样；放入瓷盘中，在105℃±5℃烘箱

中烘干2h 以上，在干燥器中冷却；

◆将金属杯、漏斗内部清理干净；将漏斗底部阀门关闭，用铲子将烘干、

冷却的粒状纤维缓慢装人漏斗中；将漏斗底部置于金属杯上部约 40mm 处，

打开阀门，让纤维在自重作用下落入金属杯中；

◆用直尺刮除金属杯上多余的纤维，并平整表面；试验过程中，不要振

动、挤压金属杯中的纤维；

◆将瓷盘在天平上清零，将金属筒中纤维移入瓷盘称取纤维质量m. , 准

确至0. 01g;

◆将金属杯放到天平上清零，用23℃±0. 5℃纯净水装满金属杯，擦净

杯外壁上的水，称取水的质量m, , 准确至0. 01g.

How to use granular wood fiber loose square density tester:

◆According to the quarter method, take 2 100g±1g fiber samples; put them in a porcelain dish and oven at 105℃±5℃

Dry for more than 2h in the medium and cool in a desiccator;

◆Clean the inside of the metal cup and funnel; close the valve at the bottom of the funnel, and use a shovel to dry,

The cooled granular fiber is slowly filled into the funnel; the bottom of the funnel is placed about 40mm above the metal cup,

Open the valve and let the fiber fall into the metal cup under its own weight;

◆Use a ruler to scrape off the excess fiber on the metal cup and level the surface; during the test, do not shake

Move and squeeze the fiber in the metal cup;

◆Clear the porcelain plate on the balance, move the fiber in the metal cylinder into the porcelain plate and weigh the fiber mass m., accurate

Confirmed to 0.01g;

◆Put the metal cup on the balance to zero, fill the metal cup with 23℃±0.5℃ pure water and wipe it clean

The water on the outer wall of the cup, weigh the mass of the water m,, accurate to 0.01g.
