Stable friction coefficient
Friction coefficient is the most important performance index to evaluate all friction materials, and it is related to the quality of braking ability.In the process of braking, friction produces heat and the working temperature of friction parts increases. The friction coefficient of general brake pads is affected by the temperature, and the friction coefficient begins to decrease, which will reduce the friction force and thus reduce the braking effect.The friction material of the ordinary brake pad is not suitable. The friction coefficient is too high, which causes the braking process direction to be out of control. When the temperature is too high, there will be the burning phenomenon, and the braking effect will become worse, and the phenomenon of scraping the brake disc may also occur.Even when the temperature of the brake disc is as high as 650℃, the friction coefficient of the brake disc is still 0.45~0.55, which can guarantee the good braking performance of the vehicle and overcome the shortcomings of ordinary brake discs.
comfort
In the comfort index, the car owner is often most concerned about the noise of the brake pad.Noise is caused by the abnormal friction between brake pads and friction discs. The causes are very complicated. Braking force, brake disc temperature, vehicle speed and climatic conditions may all be the causes of noise.Noise is also the common brake pad for a long time can not solve the problem.
Excellent material properties
Ceramic or NAO organic brake pads with large particles of graphite, potassium titanate, high temperature resistant mineral or synthetic fiber and other high-tech materials, with high temperature resistance, abrasion resistance, stable brake, repair the injured brake disc, environmental protection, no noise, long life and other advantages, overcomes the defect of the traditional brake pad material and technique are sophisticated international advanced brake pads
Brake pads have a long service life
The service life is the index that everybody pays attention to, the life of common brake piece is in 40 thousand kilometers or so, and the life of ceramic or NAO organic brake piece is in 80 thousand kilometers above.Ceramic or NAO organic brake pads adopt unique formula materials with only 1 or 2 powder containing static electricity, and other materials are non-static materials. In this way, the powder will be taken away by the wind along with the movement of the vehicle, and will not stick to the wheel hub, affecting the appearance.The life of ceramic or NAO material is more than 50% longer than that of ordinary semi-metal.After using ceramic or NAO organic brake pads, the brake disc will not be scratched, extending the service life of the original brake disc by 20%.
Good mechanical strength and physical properties
Friction material products before use, sometimes need to be drilled, assembly and other mechanical processing, in order to make brake pad assembly.Therefore, it is required that the friction material must have sufficient mechanical strength and be able to withstand greater pressure and shear force, so as to ensure that no damage or fragmentation occurs in the process of processing or use.
It has low thermal decay
No matter disc type, drum type or special mechanical brake pad must have the same braking ability with the same effect under the condition of long time braking, high friction temperature and high speed braking under the condition of heavy load braking.
