Plastic Filter Board Parameters Analysis

Edit:Tangyin Dingyuan Engineering Plastics Co.,LtdDate:Aug 09, 2017

Here we’ll analyze three important parameters for plastic filter board :

1.      The abradability is the most important parameter for filter board .As we known ,steel is a metal and the mechanical strength is much higher than plastic ,but for abradability index ,the steel is worse than some high abrasion plastic .Our plastic filter board is made by UHMWPE ,it’s a high performance engineering plastic ,the abradability is only 0.32 contrast 7-15 of steel .Benefit by the ultrat high molecular chain ,high density molecular chain can’t be easily broken by external force ,so our plastic filter board has so high abradability .

2.      The friction rate of our plastic filter board is also in top level ,because of very low friction rate of UHMWPE ,the filter board made by this material has a friction rate of 0.15 ,we should know that the same index of stone is 0.30 ,the steel is 0.45 ,and the concrete is up to 0.60 .Comparison with these materials above ,plastic especially plastic of UHMWPE filter board has the lowest friction rate .

3.      The impact strength is also an important parameter for filter board .The liquid in filter chamber run with a high speed driving by motor’s power ,the bigger granule will strike the filter board surface ,so the filter board must have a high impact strength .The UHMWPE material filter board has the strength value of 100-160, contrast the value 300-400 of Q235 steel ,completely satisfy the need of filter press .Comparision with other plastics ,this parameter is the highest .
