Dab tsi yog cov kav lub neej ntawm nylon thiab polyurethane trolley log?

Lifespan ntawm nylon thiab polyurethane log

Nyob rau hauv lub tsev loj loj siv (100,00 pumpes tauj ib hnub, feem ntau ntawm cov chaw du, qhov nyuaj), lub neej ntawm ob lub log sib txawv txawv. Cov kev sib txawv thiab cov xwm txheej tshwj xeeb yog raws li hauv qab no:

Nyob rau hauv cov nqe lus ntawm kev siv nyiaj pib, nylon log, vim lawv lub siab hnav tsis kam, feem ntau muaj lub neej ntawm 1.5 - 2 xyoo. Qhov kev ua neej no tuaj yeem txuas ntxiv mus rau 2.5 xyoo yog siv hauv qhov chaw tsheb qis (xws li high {9} i} lub khw muag khoom zoo. Polyurethane log, ntawm qhov tod tes, yog elastic thiab yooj yim hnav, ua rau muaj lub neej ntawm 1-1.5 xyoo. Cov nyiaj no tuaj yeem ua kom luv rau 8-10 lub hlis yog tias siv rau ntawm cov vuas uas tsis muaj quav nyob hauv cov khoom lag luam tshiab) lossis nquag siv (xws li thaum lub sij hawm tshaj tawm). Qhov sib txawv hauv kev siv nyiaj hauv lub neej yog cuam tshuam los ntawm peb qhov tseem ceeb:

Ua ntej, thaj chaw ib puag ncig. Nylon log hnav tau qeeb qeeb ntawm cov nplaim hluav taws dua li cov log polyurethane tuaj yeem txuas ntxiv rau lawv lub neej ntawm cov chaw du. Thib ob, kub. Nylon ua brittle hauv qab no 0 degree, luv nws lifespan los ntawm 30% -40%. Polyurethane muag rau saum 50℃thiab yog kuj txaus ntshai kev laus los ntawm ncaj qha UV hluav taws xob, ua kom luv nws lifiappan los ntawm 20% -30%. Thib peb, txij nkawm. Ua tsis tau kom huv nylon log los ntawm cov roj thiab roj nyob rau lub sijhawm ua rau lawv muaj sia 20%, thaum muaj lub neej ua haujlwm ntev li cas yog tias yuav tsum tau muab tshem tawm sai.

Txhawm rau txuas ntxiv lawv lub neej, cov log nylon yuav tsum tso tawm deb ntawm cov kub qis thiab qis qis tsis tu ncua. Cov log polyurethane yuav tsum tau ceev kom deb ntawm tshav kub thiab tshav ntuj thiab ntxuav nrog daim ntaub mos muag. Kev Txij Nkawm Muaj peev xwm txuas ntxiv lawv lifespan los ntawm 10% -15% thiab 15% -20%, feem.
