Khoom siv ntawm PP Pipes

PP kav yog ua los ntawm polypropylene (PP). Polypropylene yog ib qho thermoplastic uas muaj tshuaj lom neeg ruaj khov, tiv thaiv tshav kub, thiab lub zog txhua yam, thiab siv dav hauv cov kav dej. PP cov kav dej tuaj yeem muab faib ua peb yam tseem ceeb raws li lawv daim ntawv thov thiab kev ua haujlwm: PP-H (homogeneous polypropylene), PP-B (block copolymer polypropylene), thiab PP-R (random copolymer polypropylene). PP-R kav dej, vim lawv qhov kub thiab txias tsis kam, siab tsis kam, thiab kev laus ua haujlwm, feem ntau yog siv hauv cov dej kub thiab dej txias. Cov txheej txheem tsim khoom ntawm cov kav dej PP suav nrog extrusion molding, qhov twg polypropylene granules yog melted ntawm kub kub, extruded, thiab ces txias thiab zoo li tus. PP cov kav dej yog lub teeb yuag, yooj yim rau nruab, corrosion-tiv taus, tsis yog{10}} tshuaj lom, thiab tsis muaj ntxhiab, ua rau lawv tsim nyog rau kev tsim cov dej thiab tso dej, HVAC, thiab kev thauj mus los ntawm cov dej tshuaj. Thaum siv cov kav dej PP, xyuam xim rau kev ua haujlwm kub (feem ntau -20℃txog 95 degree), tsis txhob raug ultraviolet lub teeb ntev, thiab siv cov cua sov fusion sib txuas thaum lub sij hawm txhim kho kom muaj kev sib khi nruj.
