粒狀木質纖維松方密度試驗儀用于測量粒狀木質纖維的松方密度，全金屬結構，金屬杯容積為10ml,結構簡單，使用方便，可隨身攜帶，手持測量。

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.

粒狀木質纖維松方密度試驗儀技術參數：

◆金屬杯容積：100ml φ40*80

◆漏斗直徑：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;

粒狀木質纖維松方密度試驗儀使用方法：

◆按四分法取2份100g±1g 纖維試樣；放入瓷盤中，在105℃±5℃烘箱

中烘干2h 以上，在干燥器中冷卻；

◆將金屬杯、漏斗內部清理干凈；將漏斗底部閥門關閉，用鏟子將烘干、

冷卻的粒狀纖維緩慢裝人漏斗中；將漏斗底部置于金屬杯上部約 40mm 處，

打開閥門，讓纖維在自重作用下落入金屬杯中；

◆用直尺刮除金屬杯上多余的纖維，并平整表面；試驗過程中，不要振

動、擠壓金屬杯中的纖維；

◆將瓷盤在天平上清零，將金屬筒中纖維移入瓷盤稱取纖維質量m. , 準

確至0. 01g;

◆將金屬杯放到天平上清零，用23℃±0. 5℃純凈水裝滿金屬杯，擦凈

杯外壁上的水，稱取水的質量m, , 準確至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.
