What does porous material mean?如何測試多孔性料的密度?
The video of the test process is as follows:
When the sample is placed in water, it will immediately absorb water.
We call these samples porous materials. As the following picture:
According to ASTM B311, B328, MPIF 42, MPIF 57 and JIS Z2501, Z2505, Z2506 In accordance with
GB/T 5163, 5164, and 5165 specifications, we designed the following products to achieve test operations.
~~Automatic vacuum siphon machines~~
This equipment is a waterproof treatment for porous (water absorbing) products and materials.
Can be used for testing the following industries:
1、Waterproofing treatment when measuring powder metallurgy’s green density, sintered density and oil content。
2、Waterproofing treatment when measuring magnetic materials’ green and sintered density
3、Waterproofing treatment when measuring fine ceramics’ green and sintered density
4、Saturation water treatment when measuring wood’s basic density
5、Saturation water treatment when measuring absorbable sponge’s bulk density
6、Saturation water treatment when measuring carborundum’s green and sintered density
7、Saturation water treatment when measuring refractory material’s green and sintered density
8、To extract vacuum when rolling over and making epoxide resin, silica gel and wax modeling
9、Saturation water treatment when measuring EVA/PE foam’s bulk density
10、To extract vacuum when doing the researches and experiments on porous and water-absorbing materials
The measurement steps are as follows:
1.Weighing in air 2.waterproof treatment 3.Weighing in air 4.Weighing in water
