Lub hardness ntawm polyethylene yog nyob ntawm nws hom thiab lub hom phiaj.
Polyethylene ntawv tuaj yeem muab faib ua ob hom loj: Cov polyethylene (HDPE) thiab qis dua polyethylene (ldpe). HDPE muaj ntau dua hardness, muaj ntau dua siab dav dav, hardness thiab lub zog, thaum LDPE muaj kev softness zoo dua, elongation thiab cuam tshuam lub zog. Tsis tas li ntawd, cov tawv hardness ntau yog li ntawm 20-90}}}, thiab qhov tshwj xeeb hardness nyob ntawm nws cov qauv thiab kev ua.
Qhov cuam tshuam ntawm hardness ntawm daim ntawv thov
Siab Hardness (xws li high-ntom polyethylene): haum rau cov ntawv thov, xws li cov ntaub ntawv tsim qauv tsev, cov raj tshuaj piping, thiab lwm yam.
Tsis muaj zog (xws li cov polyethylene tsawg): haum rau cov ntawv thov muaj zog, xws li hluav taws xob hauv tsheb, xaim thiab cable account txheej txheej, thiab lwm yam.
Lub cev cov khoom ntawm polyethylene ntawv
Polyethylene ntawv muaj cov khoom siv lub cev hauv qab no:
Kev Cuam Tshuam: Nws muaj qhov cuam tshuam zoo thiab haum rau ntau yam cuam tshuam kev sib xws.
Tsawg qhov kub tsis kam: nws tseem tuaj yeem tswj cov khoom zoo ntawm lub cev zoo ntawm cov kub qis.
Corrosion Kuj: Zoo corrosion tsis kam rau feem ntau cov tshuaj.
Cov laus kuj: tuaj yeem ua lub neej pabcuam ntev hauv chaw ib sab.
Kev Ua Tau Zoo: Yooj yim txiav, khoov thiab weld, yooj yim rau kev ua thiab kev teeb tsa.
