High Density Polyethylene yam ntxwv

High-density polyethylene muaj qhov kub thiab txias tsis kam, zoo tshuaj stability, siab rigidity thiab toughness, thiab zoo mechanical zog. Lub dielectric zog thiab ib puag ncig kev ntxhov siab tawg kuj zoo. Nws hardness, tensile zog thiab creep zog yog zoo dua li tsawg-density polyethylene; nws hnav tsis kam, hluav taws xob rwb thaiv tsev, toughness thiab txias tsis kam yog txhua yam zoo dua, tab sis me ntsis phem dua li cov rwb thaiv tsev tsawg; Nws cov tshuaj lom neeg ruaj khov yog qhov zoo, nyob rau hauv chav tsev kub nyob rau hauv tej yam kev mob, nws yog insoluble nyob rau hauv tej organic hnyav thiab resistant rau corrosion los ntawm acids, alkalis thiab ntau yam ntsev; zaj duab xis muaj tsawg permeability rau dej vapor thiab huab cua, thiab tsis tshua muaj dej nqus; kev laus tsis zoo, thiab ib puag ncig kev sib tsoo tsis zoo li tsis tshua muaj polyethylene. Hauv particular, thermal oxidation yuav degrade nws cov kev ua tau zoo. Yog li ntawd, cov tshuaj antioxidants thiab ultraviolet absorbers yuav tsum tau ntxiv rau cov resin los txhim kho qhov tsis zoo no. High-density polyethylene zaj duab xis muaj qhov kub thiab txias distortion kub nyob rau hauv kev ntxhov siab. Qhov no yuav tsum tau sau tseg thaum thov.
