Product quality is crucial, only a strict quality inspection before acoustic tube in large part to protect the quality of the acoustic tube products, only on acoustic tube rigorous testing, is responsible for the user, but also responsible for their own. Only good quality control of the enterprise, to the fierce competition in the market to gain a foothold. Many people believe that the quality of the testing process acoustic tube products do not understand, so say about the quality of the acoustic tube products stand out in those test items in this article. First: the detection of acoustic tube raw materials used is qualified, under normal circumstances acoustic tube products, raw materials for the production of pipe are optional, with high performance. Second is to check whether the product has substandard workmanship. Second: detecting acoustic tube compressive modulus of elasticity, compressive modulus of elasticity of the acoustic tube means bending force at the time, in the proportional limit of the stress and strain than rubber. Elastic modulus and elastic support compression acoustic tube has a great relationship. Third: Acoustic test tube ultimate compressive strength. Ultimate compressive strength of the acoustic tube can also be understood as a simple acoustic maximum loading capacity of the tube, so that the detection is very important, if the load-bearing properties of the acoustic tube product is not good, then there must be inferior products. Of course, whether or not qualified to detect acoustic tube, there are many items to be detected in the article does not introduce too much. Yu Feng-tai company we must do testing work products to ensure product quality. If you have any issues, you can directly consult our technical staff. Product quality acoustic tube which is subjected to inspection
