1. Function
Our brake padsis an ideal replacement of the metallic (gray cast iron) brake block. brake padsfeatures motion to the wheel and well fitness between the brake padsand brake padsshoe2. Operational heat
Our brake padswon't melt or burn and continues to work at a temperature of 250℃
It may burn but causes no flame at a temperature of ≥ 400℃.3. Materials
A. The materials of brake padsconsist of 3 main substances including reinforcing fiber, organic/inorganic filler and resin bound.
B. It has a high level of uniformity.
C. It can be separated from the backing plate.
D. It contains no asbestos, lead, zinc or other mixtures.
E. It also contains no toxic materials.
F. The hardness of the material is lower than the wheel's.
G. It causes no strong smell in friction.4. Backing plate
Backing plate for a trains' brake padsmust meet the following criteria. Firstly, it is made of ST-41 steel plate, and is constructed to transmit the braking force to the composite material. Secondly, there should be a binding structure between the composite material and backing plate, thus forming into a integrated unit and ensuring sufficient bending strength and stiffness.5. Performance
A. Excessive wear won't be caused on the surface of the wheel and the brake pads.
B. The brake padswill not cause the wheel porous or cracked.
C. It won't stick at the wheel during braking therefore won't cause uneven wheel surface.
D. It won't cause wheel slipping during full braking in wet conditions.6. Test procedure
A. Vernier caliper or other methods are used to test the dimension of the brake block.
B. Laboratory test
Specific gravity test: standard ASTM D 792 or equivalent method
Coefficient of friction test: Standard ASTM D 1894 or equivalent method
Hardness test: standard ASTM D 785 or equivalent method
Shear resistance test: standard ASTM D 732 or equivalent method
Press test: Standard ASTM D 695 or equivalent method
Bending test: Standard ASTM D 790 or equivalent method
Thermal properties test: standard ASTM D 177 or equivalent methodCharacteristic Unit Value Testing Method Specific Gravity gr/cm3 1,7 – 2,4 ASTM D792 Coefficient of Friction 0,14 – 0,22 ASTM D1894 Hardness HRR 70 – 105 ASTM D785 Crush Strength N/cm2 Minimum 2500 ASTM D695 Bending Strength N/cm2 2400 – 4000 ASTM D790 Tensile Strength N/cm2 480 – 1500 ASTM D3039 Shear Strength N/cm2 1500 - 3500 ASTM D732 Heat Resistance: 250ºC
Result: Does not melt and burn for continuous use.
≥ 400ºC
Result: May burn but does not cause the flame.25KG double-layer woven bag with fumigation-free wooden pallet.
