The pressure connection pipe and the joint is an important factor that affects the pressure calibration work. Therefore, the American company China launched a set of pressure calibrator matching the pressure to take over the fittings F700pak, in order to facilitate user use and reduce because the connection between the takeover mismatch caused by the leakage problem.
Rust steel Screw, the material is. Imported 9cr18mov stainless steel material, its prominent feature is corrosion-resistant! Tube
To buy a good screw material pipe fittings, you can understand the knowledge of the plastic screw in accordance with the geometric shape of the three sectors: feeding area: Fixed screw groove deep groove, its function is responsible for preheating and plastic solid transport and push. You must ensure that the plastics begin to melt at the end of the feed segment-that is, preheat to the melting point. The general length is: Non-crystalline (as, ABS, PS) about 48~58%l, crystallinity (PA, POM, PE, PP, CA) about 48~58%l, plus fiberglass about 45~55%l.Tube
Compression zone: Tapered spiral groove teeth deep, the function of the plastic material melting, mixing, shearing compression and pressurized exhaust. Plastic will be completely dissolved in this section, the volume will shrink, so the design of the degree of compression is very important. Tube
The general length is: Non-crystalline (as, ABS, PS) about 25~35%l, crystallization (PA, POM, PE, PP, CA) about 22~32%l, add glass about 28~40%l, thermal sensitivity (PVC) 100%l metering area: screw groove fixed ditch deep, its main function of mixing, melt adhesive transport, In addition to measurement, it is necessary to provide sufficient pressure to keep the melt uniform temperature and stabilize the flow of molten plastic. The general length is: amorphous (AS, ABS, PS) sex about 15~58%l, crystallization (PA, POM, PE, PP, CA, etc.) about 48~58%l, with a glass of about 45~55%l.Tube
Polyether ether ketone resin is a kind of special engineering plastics with excellent performance, compared with other special engineering plastics have many obvious advantages, high temperature resistance, excellent mechanical properties, self-lubricating, corrosion resistance, flame retardant, peel resistance, radiation resistance, stability, hydrolysis and easy to process, etc., in aerospace, automotive manufacturing, electrical and electronic, Medical and food processing fields have been widely used.Tube
