The effect of low pressure on the volatile substances in the high and low temperature low pressure test chamber: the decrease in pressure will lower the boiling point of the liquid. For liquids with a high saturated vapor pressure at normal atmospheric conditions at sea level, the low pressure causes it to evaporate and even boil. Lubricating oil or grease is the same as above. After obtaining a certain amount of energy, the molecules in the liquid will leave the surface of the liquid and enter the surrounding air. These molecules will collide with the air molecules in the atmosphere, and some will collide back to the surface of the liquid and be trapped. This evaporation process is a balancing process. When the atmospheric pressure is lowered, the air density is lowered, and the probability of collision of molecules volatilized into the liquid in the air is lowered, the possibility of being hit back onto the surface of the liquid is greatly reduced. Therefore, the rate of liquid volatilization under atmospheric conditions will be greatly increased. Reduced pressure will accelerate the volatilization of the lubricating oil (or grease), which will cause the friction of the parts to increase and accelerate the surface of the moving parts.
The plasticizer in the organic material will accelerate to volatilize due to the decrease in gas pressure. The volatilization of the plasticizer causes the organic material to age and change its mechanical or electrical properties. Volatilization of volatiles can contaminate the product and its surrounding objects, causing contamination or even corrosion of the product or object. The equipment that simulates this environment is the YASELINE high and low temperature low pressure test chamber.
