1, cov khoom siv sib txawv, tuaj yeem siv cov hlau txuas txuas, cov kab uas loj loj yuav tsum tau flange txuas. Nrhiav ib qhov kev sib txuas ob zaug, ib tus PB, ib tug yog PERT, PB yog txawv ntawm PERT raw khoom, tsis tuaj yeem yog qhov txuas.
2, PP-R (polypropylene random) tube hu ua peb hom polypropylene yeeb nkab thiab tseem hu ua PP-R yeeb nkab lossis PPR yeeb nkab, nrog lub zog txuag, kev tiv thaiv ib puag ncig, siab zog, corrosion tsis kam, nrog tus sab hauv puab muaj qhov zoo ntawm qhov ntsuas , kev tsim kho thiab kev lag luam yooj yim, kev ua haujlwm ntev, kev siv dej hauv tsev, kev siv dej thiab faj siv, dej hauv nroog thiab cov chaw hauv nroog, dej thiab hluav taws xob . PP-R yeeb nkab yog ua los ntawm cov qauv copolymerized polypropylene thiab yog extruded rau hauv cov hlab thiab molded rau hauv cov hlab.
3, PE-RT tub yees, tshav kub ntawm cov tshuaj tiv thaiv polyethylene yog Polyethylene ntawm cov txos hauv cov dej txias tsis xa cov lus Askiv acronym, yog hom dej kub yuav siv rau cov crosslinked polyethylene yeeb nkab, nws tseem ceeb tias nws cov kev tsis sib thooj, tsis muaj crosslinked polyethylene yeeb nkab ".
