Product Description

Flame Arrestor that we are offering is a combination of flow meter, pressure column, needle valve, air compressor, air container and varied other contact components & parts. This type of devise is ideal to be utilized in varied work places, which are prone to high chance of accidents. Such equipment helps to prevent an ignited atmospheric vapour cloud from propagating beyond the product into the tank or vent line. In addition, the offered Flame Arrestor is widely demanded in storage tanks, petrochemical industries, oil refineries and allied sectors due to its higher efficiency, constant performance, simple maintenance and longer functional life.

We own the independent intellectual property rights over the polyethylene and polypropylene micro-pore made by us these products are widely used in water purification and filtration, sewage treatment, medical treatment and public health, air filtration, storage batteries, chemical products, agriculture and daily necessities.

Products Features :

  • This product is prepared based on the air floating semi-melt mould pressing method under the real-time control of a microcomputer,in combination with power semi-melt control technique under air floating state,control technique of porous membrane product conformance,and control technique of porosity changes in a gradient form along the thick direction during micro-pore molding.
  • This product is characterized by excellent resistance to flame, acid fog, acid and alkali, prevent the electrolyte corrosion to the car and the surrounding environment.
  • The minimum pore size of product can be 50-150um with high porosity.
  • It is very excellent in ventilation performance and filtration of acid fog and waste gas. In addition, its water repellent and hydrophobic nature outdistance the like products (made in Europe and America) in existing market.
  • This product is remarkable in its mechanical strength and even in the conformance of dimension scale, and has good acid resistance and bearing capacity, which can rival like products in foreign markets.
  • Our micro-pore polyethylene and polypropylene can be designed subject to the requirements of users on the product, and can be made into series such as polypropylene and polyethylene compounded micro-pore filter element, and PTFE disc and films.

Appearance :

  • The appearance must be no Lacerate,crack,and shall be no iron powder or particle into the products. The size tolerance of the top and the side must within 1mm.For the local defect, the maximum size should within 1mm,and it can be only one place is local defect

Quality characteristics :

This Standard used for sealed lead-acid Battery Explosion-proof Filter.

Acid-proof Test :

  • Test the sample weight,show as m1 and the unit of the weight should be 0.0001g;
  • Put the sample at 40oC temperature 100h in 1.300/20oC H2SO4;
  • Put the sample out and use pure water wash the sample and the sample must show no acid feature after washed;
  • Put the sample in drying oven with 100oC temperature till the weight of sample with no change;
  • When the sample cold,test the weight in room temperature, the weight show as m2;

    Acid Proof = (M1-M2) / M1x 100%

Acid-proof Test :

  • Test the sample weight,show as m1 and the unit of the weight should be 0.0001 g
  • Put the sample at 40oC temperature 100h in 1.300/20oC H2SO
  • Put the sample out and use pure water wash the sample and the sample must show no acid feature after washed;
  • Put the sample in drying oven with 100oC temperature till the weight of sample with no change;
  • When the sample cold, test the weight in room temperature, the weight show as m2;

Air Permeability test :

  • Test the air permeability according to the following test device.
  • Set the air ventilation in below device, read the pressure column is the air permeability of the flame arrestor.
  • The pressure difference must be 0mm when there is no flame arrestor put in the device.
  • The sample must be tested under room temperature and 20 pcs sample must be tested.
