Yuav ua li cas rail pads ntim thiab xa?
Railway rubber ncooyog ib qho tseem ceeb hauv cov qauv kev tsheb ciav hlau, uas yog qhov sib txuas ntawm cov ntsia hlau thiab cov pob zeb ua vaj tse kom tiv thaiv kev vibrating thiab cuam tshuam. Tsis tas li ntawd, dhau los ntawm nws txoj kev tsheb ciav hlau teeb liab tuaj yeem nyob hauv lub xeev ntawm kev sib cais hluav taws xob.
Railway pads ua haujlwm txoj cai
Lub hauv paus ntsiab lus ntawm railway pad ua hauj lwm feem ntau yog raws li cov ntaub ntawv railway pad ' elasticity thiab lawv cov qauv tsim:
- Thaum cov tsheb ciav hlau hla, railway pads yuav muaj elastic deformation. Hom deformation no tuaj yeem nqus cov tsheb ciav hlau 'dynamic load, thiab txo qhov ua rau muaj kev cuam tshuam nruj rau cov ntsia hlau thiab khi.
- Dab tsi ntxiv, cov ntaub ntawv ntawm railway pads, zoo liroj hmab, EVA, los yogHDPE, txhua tus muaj lub peev xwm zoo rau absorbing thiab dispersing zog. Thaum lub tsheb ciav hlau hu rau lub tsheb ciav hlau, lub tsheb ciav hlau pads nqus thiab tawg lub zog kom txo qis kev tsheb ciav hlau txoj kev tsheb ciav hlau qhov kev co thiab suab nrov.

- Tom qab lub tsheb ciav hlau hla, lub tsheb ciav hlau yuav rov qab los rau nws qhov qub thiab lub xeev. Uas ua kom lub railway ncoo lub durability thiab stability thaum siv ntev.
Rail pads ntim thiab xa tawm
Rail pads tau ntim rau hauv ntau, feem ntau muab tso rau hauv pallets lossis hauv cov thawv ruaj khov, siv cov ntaub thaiv zoo li yas zaj duab xis thiab cushioning (npuas qhwv / ua npuas ncauj) los tiv thaiv kev puas tsuaj los ntawm kev poob siab, kev co, thiab huab cua thaum thauj los ntawm tsheb lossis tsheb ciav hlau; lawv tau sau meej meej nrog cov ntsiab lus ntawm cov khoom, qhov hnyav, thiab kom muaj nuj nqis rau kev taug qab logistical.
Ntim Cov Lus Qhia
- Bulk Stacking: Cov ntaub qhwv tau muab tso ua ke hauv ntau qhov ntau.
- Cushioning: qhwv hauv cov yas los yog muab tso nrog ua npuas dej / npuas qhwv kom nqus cov cuam tshuam thiab tiv thaiv qhov chaw.
- Kev Ruaj Ntseg: Cov hlua khi, ntsws- qhwv, lossis muab tso rau hauv cov thawv ntawv los yog cov thawv kom ruaj khov thiab tiv thaiv kev hloov pauv.
- Kev tiv thaiv los ntawm Elements: Npog los tiv thaiv los ntawm tshav ntuj, nag, thiab noo noo.
- Labeling: Pob ntawv kom meej meej nrog cov qauv, kom muaj nuj nqis, qhov hnyav, thiab cov lus qhia tuav.
Kev siv cov railway roj hmab ncoo tuaj yeem txhim kho kev thauj mus los ntawm cov tsheb ciav hlau thiab txo lub sijhawm ntawm kev saib xyuas rau kev hla kev tsheb ciav hlau kom tsis txhob muaj hluav taws kub nyhiab los ntawm lawv. Piv nrog rau lwm yam railway roj hmab pads,GNEE RAIL's cov khoom pabcuam lub neej tuaj yeem ncav cuag 3 zaug ntev dua li lawv. Cov kev ntsuam xyuas tau ua pov thawj tias qhov siab ntawm ntau tshaj 80 tons tuaj yeem ruaj khov yam tsis muaj deformation rau peb cov khoom. Siv high- thev naus laus zis ntau lawm, GNEE's railway roj hmab ncoo xaiv cov roj hmab zoo li cov khoom siv raw, ua tib zoo tsim thiab ua nrog cov qauv kev tshawb fawb.
