Suction vehicle braking system is a safety system for driving the vehicle. It is a protective line to ensure the safety of drivers. Drivers should pay attention to the inspection and maintenance of the braking system to ensure the health and safety of the braking system and avoid unnecessary injuries.
Regular brake maintenance:
Regularly check the thickness of the brake pads or brake shoes. No matter what the brake system, brakes (disk type) or brake shoes (drum type) are used to complete the braking. Therefore, check the thickness of the brake pads or brake shoes regularly. When it is found that its thickness is close to or less than the minimum thickness specified by the manufacturer, it should be replaced immediately. While inspecting the brake pads, check the wear of the brake discs or brake drums. If there is a dent on the contact surface, use a CD or drum to ensure that the contact area with the brake pads increases the braking force.
For cars braking on the oil line, check the fluid level of the brake fluid before leaving the car. If it is found that the oil level has dropped, check immediately whether there is a leak in the brake oil circuit. Brake fluids will fail due to the absorption of moisture from the air for a long time. The brake oil should be replaced regularly according to the manufacturer's regulations. It is best to change it once a year.
For the air brake system, pay attention to constantly drain water from the system and replace the dryer regularly. Water in the air system can corrode the pipe and affect the braking effect. In severe cases, it can even cause the brake system to malfunction. In addition, check the pump's working condition and the wear of the air pump belt. If problems are found, they must be promptly replaced.
The brake pad replacement cycle is usually based on whether the brake warning light on the instrument panel is on or not as the judgment basis for changing the brake shoe. Although all vehicles have this warning system, some of them directly sense the thickness of the brake shoe, while others are The brake shoe has been completely worn out, and the brake fluid is thus extremely lowered, causing the warning light to light up. At this time, bright irons will be seen near the rim of the tire. Therefore, every time you enter the factory, you must check whether the brake pads can be used, and replace the brake pads near the end of life, instead of just believing the warning lights.
Routine Maintenance of the Brake System Clean, high-quality brake fluid is essential to the safety and braking system. If the brake fluid is dirty, let go and flush the entire system, then fill the main cylinder with new fluid. Brake fluid can not be reused. When the brake system is being maintained, it is the most important to check the brake fluid level regularly. It is guaranteed to check once a month. When servicing the brake assembly, it should be in a well-ventilated place and equipped with certified respiratory respirator.
Before checking the oil brakes, clean the dirt on the main cylinder to prevent dirt from falling into the tank. Remove the fasteners (usually the pins) and the lid. For uncalibrated cylinders, keep the liquid level 6 mm from the top of the cylinder. If there is a scale, just keep the liquid level higher than the scale. If the master cylinder needs to be refueled, add a heavy duty brake fluid that meets the dot3 or 4 specifications. Be careful not to put the brake fluid on the paint. It is very corrosive and can damage the vehicle finish.
Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat Stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective thermal stabilizer added in the processing of PVC films, and can prevent finished films caused by excessive exposure to sulfides.
Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.
Widely used to make cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a wax paper polish, and an emulsifier for glyceryl stearate.
The product is used as a lubricant, defoamer and food additives in the food industry as a raw material for glyceryl stearate, sorbitan stearate, and sucrose esters. Used as the raw material of additives and the raw material of daily chemical products.
