Mechanical zog ntawm HDPE Rail Pad
HDPE (High-Density Polyethylene) rail pads yog cov khoom siv hauv kev tsim kho tsheb ciav hlau los muab cov txheej txheem cushioning nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb ua haujlwm (kev tsheb ciav hlau khi). HDPE rail pads yog tsim los muab tso rau nruab nrab ntawm lub hauv qab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb pw tsaug zog. Lawv feem ntau muaj qhov chaw contoured uas phim cov profile ntawm txoj kev tsheb ciav hlau los xyuas kom meej kev sib cuag thiab thauj khoom xa tawm. Cov ntaub qhwv tuaj yeem muaj grooves lossis lwm yam nta kom haum rau cov tsheb ciav hlau fasteners thiab muab kev ruaj ntseg haum.
HDPE rail pads yog siv nyob rau hauv ntau yam railway systems thoob ntiaj teb, nrog rau hnyav thauj, freight, neeg nrog caij, thiab tsheb thauj mus los hauv nroog. Lawv tsim nyog rau ob qho tib si kev tsim kho tshiab thiab rov qab kho cov kab uas twb muaj lawm los txhim kho kev ua haujlwm thiab txo cov nqi tu.
