AGM Seprator-Battery Separator

Fiberglass Battery Separator for lithium cells is made of fiberglass filaments.The fiberglass separator is characterized by high liquid absorptivity,low specific resistance,excellent chemical stability and high mechanical strength.It can absorbs all electrolyte uniformly onto themselves and stabilized the discharge performance of cells.

Application:
Used as separator sheets between anodes and cathodes in lithium thionyl chloride (Li-SoCl2) cells or lithium manganese (Li-MnO2) cells.

Absorptive Glass Mat Separator(AGM) for valve regulated sealed lead acid battery(VRLA) is made of ultrafine fiberglass filaments(0.4-3 ¦Ìm in diameter) by wet-laid process.AGM separator is the most important and central material of VRLA .
AGM separator has excellent performance of acid resistance, uniform thickness,high porosity,rapid electrolyte absorption, good tensile strength, better compression performance guaranteed a certain amount of pressure between poles, good insulation properties and so on.

AGM separator has played in the major fixed battery electrolyte to provide charging and discharging of hydrogen in the production of composite bipolar channel, impeding the bipolar active substance off and slow down the formation of lead dendrites to reduce the electrolyte during charge and discharge in the loss of so that less maintenance-free VRLA batteries to achieve the purpose of maintenance, to extend battery life .

Applications: UPS power supply, power system, railway systems, communications equipment, emergency lights, fire and security systems, engines, power cars and motorcycles, sealed power, solar energy, wind energy.

Air Filter Paper-Fiberglass Air Filter Paper

 

Fiberglass Air Filter Paper is made of fiberglass filament by wet-laid process.Characterized by uniform fiber distribution,high dust holding capacity,low resistance and high strength . The fiberglass air filter paper is an ideal materials for air filtration.
Application:used for primary,medium and high efficincy air filters in air condition systems in medical,electronic,food and textile industries.

Composite Fiber Filter Paper is made of ultrafine fiberglass filaments as filtration layer, which is coverd with sythetic or natural fibers as protection layers on both sides.So that the mechannical strength of composite filter paper is improved and the problem of "secondary pollution" due to the fall-off of ultrafine fiberglass filaments is solved.As a novel filtration material,the composite fiberglass filter paper is characterized by high filtration effcienty,high dirt holding capacity,low resistance,high mechanical strength and stable chemical property.

Application:
1.Filter solid impurities from oil or water;
2.Filter dust and aerosol particles in air;
3.Filter compressed air from compressor;
4.Filter water for nuclear power station;
5.Filter water for oil fields;
6.Filter hydraulic oil for servo system of hydraulic drivers in marines and heavy-duty machineries ;

ePTFE Membrane Filter

ePTFE Membrane Filter £¨expanded microporous polytetra fluoroethylene £© is a new filtering material.It isvery different from fiberglass textile or composite fiber needle mat,on which surface compounded with expanded microporous polytetra fluoroethylene.It widely used in cement ,chemical and metallurgical industries for smoke dust purification and material recycling.
Features:
1.Surface filtration to avoid filter media clogging from conventional deep filtration;
2.High filtration efficiency .It has a dust collection efficiency of 99% for fine dust under 1micron and 100% for dust over 5 micron;
3.Low filter resistance,reduce energy consumption of system;
4.Saveing dust cleaning time,prolong service time;
5.Greater airflow ,less land required for quipment and lower down investment;

Carbon Fiber Mat

Carbon Fiber Surfacing Mat is one type of new substrate materials for FRP/GRP articles.It's characterized by uniform fiber distribution,smooth surface,excellent permeability and absorbability.In many fields and composite material applications,carbon mat can play outstanding characters of carbon fiber,and decrease producing cost. Effectively.

Application:
1.Carbon Fiber Reinforced Plastics
Carbon fiber mat can make the surface of FRP/GRP articles smooth,conceal veins of woven roving,fabric or textile,pliantly affix the surface of complex shaped articles;
2.Chemical Vessels and filtration
Carbon surfacing mat is used to produce all kinds of pipes,tanks and sumps because of corrosion for strong acid & alkali and seawater, and also to filter corrosive gas and liquid;
3.Cover of Electronic Instrument
Covers made of carbon surfacing mat has more thin and lighter shell,high strength and stiffness for creep resistant,and EMC & RFI protection;
4.Electronic Industry
Electronic components , devices & industrial equipment stage decorated with carbon fiber surfacing mat can effect EMC & RFI protection and ESD,and this mat can be used in reflection satellite ;
