shenzhen's sharp to share with you how to measure the nylon corrugated pipe, the method of flame retardant nylon bellows surface hardness:
nylon bellows, flame retardant nylon corrugated pipe, also known as nylon thread tube, often as a mechanical equipment of cable protection, because it is used in the middle of the mechanical equipment, and machinery and equipment, some necessary contact occurs between the hose will have certain resistance to mechanical stress, the stress is refers to the surface of the nylon corrugated pipe, flame retardant nylon bellows hardness, it is show that nylon thread tube quality is an important indicator of the following we will be on the surface of the nylon corrugated pipe, flame retardant nylon bellows hardness measurement are analyzed, let you more thorough understanding, to deepen the impression.nylon bellows, flame retardant nylon bellows surface hardness measurement method has three, respectively is shaw, brinell hardness and rockwell hardness, these three methods to shaw hardness measurement method is quick and accurate, so in one of the most widely used in conventional detection, here we detailed introduce shaw hardness measurement method. Shaw hardness measurement method have special measuring tool, called shaw hardness tester, the main part of mainly includes the following several parts: standard spring pressure, the pressure head. The pressure head for conical, head plane is 0. 8MM。 In the measurement of the surface of the nylon corrugated pipe, flame retardant nylon bellows hardness when the main steps are the following a few steps, the corrugated hose pressure head on the smooth steel or glass, verify the hardness value is 100, the corrugated soft GuanPing on smooth metal plate sample, for 1 kg load, head pressure time for 30 s, the record values for shaw hardness value.
