PE gas pipe thiabPE kav dejnyob rauPE cev.PE kuj hu ua polyethylene.Hauv ntiaj teb, cov kav dej polyethylene tau muab faib ua tsib qib: PE32, PE40, PE63, PE80 thiab PE100.Cov ntaub ntawv siv rau cov kav dej polyethylene thiab cov kav dej polyethylene feem ntau yog PE80 thiab PE100, uas nyuaj rau kev siv, tab sis nws kuj coj ntau yam kev phom sij rau kev siv cov kav dej PE.
Yog li, National Bureau of Standards tau hloov kho ntau yam rau tus qauv tshiab GB / T13663-2000, qhia tias cov qib sib txawv ntawm PE80 thiab PE100 ntawm cov kav dej xa dej sib haum rau qhov sib txawv ntawm lub zog, tshem tawm qhov tensile lub zog ua haujlwm hauv qub tus qauv, thiab nce lub elongation thaum so.(Ntau tshaj 350%), uas qhia txog qhov yooj yim toughness.
Kev tsim khoom hauv tsev ntawm cov kab ntau lawm no feem ntau yog ua los ntawm PE100 raw khoom.Qhov no feem ntau yog vim muaj kev vam meej hauv xyoo tas los no.Tus nqi raw khoom ntawm PE100 yog yuav luag tib yam li ntawm PE80.Txawm li cas los xij, hais txog kev ua tau zoo, PE100 yog qhov zoo dua li PE80 raw khoom.Tsis tas li ntawd, PE kav dej thiab PE roj yeeb nkab extrusion kab khoom siv tau raug txhim kho tas li, thiab cov kav dej PE tau mus txog qib thib ib thoob ntiaj teb.
