D1473 Brake Pads

The relationship between the formulation and the process in the production of brake pads.

A great deal of practice has been done on improving the performance of friction materials, improving processing methods and extending service life. As a result, the surface must be designed through a reasonable formulation and process. After determining the materials and ratios used in the formulation, the process needs to be selected. There are many kinds of processes for formula design. It is necessary to select a suitable process. First, the components are mixed together, and then the base adhesive is tightly combined with the reinforcing material and the powder material by a hot pressing process to form New materials with special properties.

In the production of friction materials, from the mixing of pressed plastics to the molding of products, it is a relatively complicated process. The process factors that need to be considered in the formulation design mainly include material mixing and press molding. For the compounding process, the pressed plastic mainly relates to the uniformity and dispersibility of the mixing, the compression ratio and the fluidity. Whether the pressed plastic can be evenly mixed and has good dispersibility, mainly in the rationality of the formula design and the mixing ability of the selected equipment.

For example, some asbestos fibers have poor dispersibility and are easy to agglomerate when mixed, which affects the properties of the molding and products. The formula design should select a mixing device with a high opening capacity and a suitable process to achieve uniform opening and mixing. Purpose: The compression ratio of the pressed plastic is the ratio of the density of the pressed plastic after molding to the apparent density of the pressed plastic before molding. The compression ratio is too small, the volume of the pressed plastic is large, and it is difficult to feed, which also causes a large cavity for the mold design. Difficulty; fluidity is the ability of a pressed plastic to flow under a certain temperature and pressure. It reflects the ability of a compressed plastic to fill a cavity under specified temperature and pressure conditions. The composition of the formula design is unreasonable, the flowability of the pressed plastic is very poor, and it is difficult to press-form. The quality of the base adhesive and its molecular weight size and distribution seriously affect the fluidity of the pressed plastic, and the shape of the reinforcing material and the friction modifier are also Will affect the fluidity of the pressed plastic.

Replacement of car brake pads

The brake pads of a car are a consumable part that needs to be replaced after a certain period of time or mileage. After the brake pads are replaced, the contact surfaces of the new brake pads and brake discs may not be very good, which may affect the braking performance of the car, and severe brake failure. The newly replaced brake pads need to be run-in, in order to better match the brake discs for better braking.

The newly replaced brake pads should be used as much as possible in the running-in, and try not to use the sudden braking during the running-in period. After the running-in brake pads still need to pass through a few hundred kilometers to achieve the desired effect, be sure to drive carefully to prevent accidents. For the method of running-in, first of all, it is not strictly required that every time you need a very accurate speed, you can start the brakes when you accelerate to about 60-80km/h. Secondly, when you brake to 10~20km/h, keep your eyes. Look at the road and make sure that the road is safe. It takes about ten braking steps.
