air filter paper made in china, 1.good waterproof, 2.long service life, 3.high efficiency, 4.better stiffness - details see: https://www.machineto.com/lowest-price-high-quality-truck-car-oil-filter-paper-made-in-china-10220622

Six major technical indicators of air filter paper made in china

Grammage

------To test the quality of air filter paper made in chinain the unit area by the electronic balance.Grammage is the basic property parameter of filter paperand 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 ofair filter paper made in chinainside 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 ofair filter paper made in china.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 theair filter paper made in chinaand paper board.

GB/T 2679.14-1996

Burst Strength

-------It means that the maximum pressure ofair filter paper made in chinabears 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 ofair filter paper made in china

GB/T 454-1989

Stiffness

--------It mesns that,in the standard situation,the moment of theair filter paper made in chinaneeds 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
