Film (commonly known as: pressure-sensitive paper) application examples, inspection method of surface pressure distribution of engine cylinder gasket. Place pressure-sensitive paper on both sides of the engine cylinder gasket (engine body and head), and place pressure-sensitive paper on both sides of the engine cylinder gasket. In this state, close the engine body and head and tighten the bolts. Then disassemble the engine body and head, take out the pressure-sensitive paper and observe its color development status. Check that the color around the inspection points does not have a certain deficiency, and the pressure value is within the specified value. The color of the entire engine is distributed evenly from left to right and up and down. Use pressure-sensitive paper models of ultra-high pressure, high pressure, medium pressure
to check the brake pads, the contact area of the friction surface (braking surface) and the uniformity of the contact pressure. Check the changes when changing conditions or after using it a specified number of times. The measurement method is to put pressure-sensitive paper between the brake pads, friction pads and drive system, and run the brakes. After operation, take out the pressure-sensitive paper and observe its color development status. Check points: The contact area reaches a certain area, and the pressure value of the contact part is uniform and above a certain value. The three operating states of slow, normal, and sudden, as well as changes in temperature/humidity, the uniformity of the area and contact pressure after a specified number of uses (equivalent to the running distance), and whether the pressure is maintained above a certain value. Use pressure-sensitive paper models for low pressure and ultra-low pressure
Carburetor (carburetor) Confirm the sealing tightness of the metal sealing joint and check whether the specified pressure is maintained at a certain value. The measurement method is to put pressure-sensitive paper into the joint, tighten the bolts to fully combine, then take out the pressure-sensitive paper and observe the color development status. The key points to check are that the hair color of the combined parts is uniform and the hair color is above the specified concentration value. If a part of the hair color is light, even if the overall hair color is above the specified concentration, the balance is not good because the force is uneven, so deformation or distortion may occur. Use pressure-sensitive paper models of medium pressure, low pressure, ultra-low pressure
and oil pan to check the sealing of the joint that prevents oil pan leakage. The measurement method is to put pressure-sensitive paper into the joint, tighten the bolts to fully close them, then take out the pressure-sensitive paper and observe its color development status. Use pressure-sensitive paper models of low pressure and ultra-low pressure. The area and pressure value of the clutch plate contact part should be uniform and above a certain value. Check changes when changing conditions and changes using a prescribed number of times. The measurement method is to put pressure-sensitive paper between the clutch plates and run the clutch. After operation, take out the pressure-sensitive paper and observe its color development status. Check points: The contact area is above a certain value, and the pressure in the contact part is uniform and above a certain value. Check operating conditions for changing operating speeds and changes in temperature/humidity. The uniformity of the area and contact pressure during operation after a specified number of uses (equivalent to the running distance), and whether the pressure is maintained above a certain value. Use pressure-sensitive paper models of low-pressure, ultra-low pressure, extremely ultra-low pressure
and tires to check the ground contact pressure of the tires. The measurement method is to stick pressure-sensitive paper on the ground, put the tire on the pressure-sensitive paper, and add the weight. Or run it for a while, watch the color development status of the pressure-sensitive paper, and check the ground contact pressure. Check points: The contact area is above a certain value, and the pressure in the contact part is uniform and above a certain value. Check the operating status of changing operating speed, changes in bending status or temperature/humidity, uniformity of area and contact pressure after running a specified distance, and whether the pressure is maintained above a certain value. Use pressure-sensitive paper models of ultra-low pressure, extremely ultra-low pressure
When the air bag collides, check the impact pressure between the air bag and the human body or various parts of the automobile. The measurement method is to affix pressure-sensitive paper to various parts of the human body model or the automatic vehicle that need to be tested (such as the front glass, instrument panel, etc.) for the collision test. The collision values between the airbag and each part of the human body or the automatic vehicle will be recorded on the pressure-sensitive paper. , remove the pressure-sensitive paper for inspection. Inspection points: Confirm the collision area and the number of pressure peaks, and confirm the overall weight. Use pressure-sensitive paper models of ultra-low pressure, extremely ultra-low pressure
and collision tests to measure the pressure on various parts of the automatic vehicle during the collision test. The measurement method is to affix pressure-sensitive paper to various parts of the automatic vehicle that need to be tested (such as the body, instrument panel, etc.) for collision experiments. After the collision test, the collision value between the airbag and the human body or various parts of the automobile will be recorded on the pressure-sensitive paper, and the pressure-sensitive paper will be removed to check the pressure. Inspection points: Confirm the collision area and the number of pressure peaks, and confirm the overall weight. Using the pressure-sensitive paper models of high pressure, medium pressure, and low pressure
, the sealing test method of packaging is to put the pressure-sensitive paper into the sealing opening of the package, and then apply pressure according to the specified amount after it is fully combined. Then take out the pressure-sensitive paper and observe its color development status. Key points to check: There are no certain defects in the color around the packaging seal, or the pressure value reaches the specified value, and the overall color distribution is evenly distributed from left to right, top to bottom. Use pressure-sensitive paper models of high-pressure and medium-pressure pressure analysis systems.
In improving products Accurate pressure measurement and analysis is essential in terms of quality, reduction of consumption and manufacturing time. High-tech technology is used to create very thin and stable pressure-sensitive paper to measure pressure. The system analyzes pressure more accurately and diversified. This system improves on previous products and has better performance. With this system, pressure values are visualized and a full-color image can be analyzed on a monitor. These applications can be successfully used in various product development, improvement and maintenance of manufacturing equipment
