The tensile strength of the shower nozzle hose needs to be considered when designing. The test piece can be drawn at a speed of 10mm/min to detect the extra load generated when it breaks, and then divide the minimum cross-sectional area of the test piece. The results can be drawn.
The specific tensile strength of the shower nozzle hose is closely related to temperature changes. When the temperature is relatively high, the tensile strength of the shower nozzle hose will decrease, and when the temperature is low, the tensile strength will increase.
However, when the temperature is lower than zero, brittleness will appear instead, so when designing, you should pay attention to the temperature change of the occasion.
Generally speaking, the tensile strength of the shower nozzle hose is relatively high when the ambient temperature is at 20 degrees.
In addition, as the use time increases, the strength of the shower nozzle hose will gradually decrease, but the elongation rate will increase accordingly. Therefore, it is necessary to consider the strength reduction caused by long-term use during use.
The shower nozzle hose reduction rate will also become smaller and smaller as the use time increases. According to calculations, after one thousand hours of use, the reduction rate will not decrease.
Generally, when designing, the service life of shower nozzle hose is relatively long, theoretically it can reach 50 years. Of course, the specific service life is affected by many factors.
