Six major technical indicators of filter paper

Grammage

------To test the quality of filter paper in the unit area by the electronic balance.Grammage is the basic property parameter of filter paper and it can impact the other properties.The stable grammage can ensure the filter quality.The unit is g/m².

Test Standard:the grammage measurement of paper and paper board

GB/T 451.2-2002

Thickness

------It is tested at 200Kpa.Thickness can influence directly the pleating amount of filter paper inside the filter in the limited spaced,which can impact the filter area.

Test Standard:the thickness measurement of paper and paper board

GB/T 6547-1998

Air Permeability

---------It means that under the certain pressure and time,the air passes through on the unit area of sample .The test pressure of Lanjiamu employs is at also the basic property and can directly impact the initial pressure of filter.The unit is L/m²s.

Test Standard:the measurement of textile air permeabilityGB/T 5453-1997

PMI Pore Size

-------Pore size is a very important property of filter paper.There is no direct relation between pore size and filter accuracy.The smaller the pore size is,the higher the filter accuracy is.The unit is um.

Test Standard for the Max and Mean Pore Size:the measurement of max pore size for the filter paper and paper board.

GB/T 2679.14-1996

Burst Strength

-------It means that the maximum pressure of filter paper bears in unit area.Burst Strength needs to meet the pressure of filter paper before the working life of filter stops,which can avoid the break of filter paper under the normal use.

Test Standard:the burst strength measurement of filter paper

GB/T 454-1989

Stiffness

--------It mesns that,in the standard situation,the moment of the filter paper needs when the paper is curved to some extent .Stiffness impacts the plesting shape of filter paper inside the filter and it also ensures that the paper pleatings can not overlap when using the filter.The unit is mN.m.

The company tests the stiffness of paper from the longitudinal direction.

GB/T 2679.3-1996

About us:Lanjiamuis Paper manufacturer

This type used for air filter,its features : using acrylic resin and the plesting temperature is not over 150°C.This paper can prevent the engine from early wear,and prolong the working hour of engine .This filter paper could ensure the customer's long-time use requirement and achieve the high cost performance.This filter paper could slow down the fall of filter fuction during the use and resist the impact of poor environment efficiently.

At last:because our corporation is Paper manufacturer ,the price is the lowest!!!
