Kev xaiv cov khoom thiab kev ua tau zoo txuam ntawm cov tsheb ciav hlau
- Dab tsi yog cov khoom siv ntawm kev tsheb ciav hlau nyob hauv qab thiab lawv cov xwm txheej muaj feem xyuam?
Cov Roj Hmab Roj Hmab Muaj Zoo Elasticity thiab cov roj rail despays thiab roj av zoo heev, tswj kev ua tau zoo ntawm -40℃rau 120℃rau kev tsheb ciav hlau muaj lub peev xwm loj thiab muaj rau cov chaw tsheb ciav hlau loj nrog cov railwing rwb thaiv tsev yuav tsum .
- Yuav ua li cas kom phim cov kev ua tau zoo ntawm kev tsheb nqaj hlau nrog cov kab mob?
Elastic modulus yuav tsum sib phim tsheb ciav hlau: hnyav ciav hlau yuav tsum muaj cov ntaub ntawv nrog cov kab sib luag me me kom muaj kev sib npaug muaj peev xwm thiab tsis muaj peev xwm; high-ceev railways xav tau150-300 mpa} mm rau qheb tsaug zog degrees . heev hardness yooj yim transmits kev co; Kev txo qis dhau yooj yim ua rau muaj kev tsis txaus siab li 10 lab los tiv thaiv ntau dua 100 lab rau kev ua kom tsis txhob muaj teeb meem licage {}}
- Dab tsi yog qhov sib txawv hauv kev pabcuam lub neej ntawm hauv qab-tsheb ciav hlau ntawm cov khoom sib txawv ntawm cov khoom sib txawv?
Cov Roj Hmab Roj Hmab Muaj lub neej kev pabcuam ntawm txog {}}}}}}}} Lub neej zoo rau ntau tshaj 7 xyoo txawm tias hauv Oily Scrararios . EPDM roj hmab cov ntaub qhwv muaj lub neej ntev tshaj plaws, mus txog {{6 xyoo, nrog kev ua haujlwm qeeb} polyurethane pads muaj lub neej kev pabcuam muaj lub neej muaj zog; Txawm hais tias hnav-resistant, lawv tau yooj yim poob elasticity nyob rau hauv lub sij hawm ntev logs {}}}}}}}}} .
- Yuav ntsuas qhov sib txuam ntawm kev sib tw hauv qab-tsheb nqaj hlau thiab cov nqaj hlau, pw tsaug zog?
Txheeb xyuas qhov haum ntawm cov ntaub qhwv thiab ntsia: Hu rau thaj tsam yuav tsum muaj ntau dua lossis sib npaug rau 90% kom tsis txhob raug ncua kev ntxhov siab rau hauv kev thauj khoom; Deformation yuav tsum koom ua ke nrog slacle excastic deformation, nrog qhov sib txawv tsawg dua lossis sib npaug} Lub ncoo ntuj ntawm cov zaus yuav tsum sib txawv ntawm cov ntsia hlau thiab cov pw tsaug zog ntau dua lossis sib npaug yog tias POSD ed ed have muaj cov ntawv deformation; Tom qab kev teeb tsa, ntug kev qhov nruab qhov siab tsawg dua lossis sib npaug ntawm 2mm qhia tau zoo heev {9} Tshawb xyuas cov pw tsaug zog zoo dua tom qab siv ntev; Cov ntoo muaj nyob ntawm cov npoo ncoo qhia tias cov kev sib txuam tsis zoo, xav tau kev hloov kho ntawm ncoo loj lossis cov khoom siv.
- Dab tsi ib puag ncig cov txheej txheem yuav tsum tau txiav txim siab nyob rau hauv kev xaiv hauv qab cov khoom siv hauv qab-tsheb nqaj hlau?
Qhov kub thiab txias yog qhov tseem ceeb: cov cheeb tsam txias xav tau cov khoom kub tsawg-tiv taus cov ntaub ntawv kom tsis txhob tawg tawg; Cov roj hmab kub yuav tsum muaj cua sov cov khoom siv kom tsis txhob muaj cov roj hmab tsis muaj teeb meem kom muaj kua qaub thiab cov khoom siv roj av; ze rau cov nroj tsuag tshuaj, EPDM lossis polyurethane pads yog qhov muaj kuab lom Kev Ua Haujlwm .
