Cov roj tsis kam ntawm rail pads thiab lawv compatibility nrog oily ib puag ncig ntawm turnout cheeb tsam
Yog vim li cas cov roj stains corrode nyob rau hauv -rail pads thiab dab tsi yog lub mechanism? Cov ntaub ntawv tseem ceeb ntawm hauv qab -rail pads yog roj hmab los yog polyurethane, uas yog cov ntaub ntawv polymer. Mineral roj thiab lubricating roj Cheebtsam nyob rau hauv cov roj stains nyob rau hauv ib tug zoo li-dissols-zoo li cov tshuaj tiv thaiv nrog polymer molecules thiab nkag mus rau hauv lub ncoo. Rau cov ntaub qhwv roj hmab, cov roj stains ua rau cov vulcanized ntoo khaub lig- txuas cov qauv ntawm cov roj hmab, so kom txaus cov saw hlau molecular; rau polyurethane pads, roj stains ua rau cov tshuaj degradation. Qhov kev xeb no hloov pauv micro- qauv ntawm lub ncoo, ua rau nws poob nws qhov qub elasticity thiab cov khoom siv kho tshuab thiab tsis tuaj yeem ua cov haujlwm buffering ib txwm.
Dab tsi tshwm sim tsis zoo tshwm sim thaum cov ntaub qhwv corroded los ntawm cov roj stains?
Roj hmab pads corroded los ntawm cov roj stains qhia pom tseeb o, nrog nce ntim, txo hardness, thiab ua mos thiab yooj yim rau deform, uas ua rau muaj kev sib haum xeeb ntau thaum tsheb ciav hlau dhau. Qee cov roj hmab kuj tawg thiab hmoov, poob elasticity. Polyurethane pads ua hardened thiab nkig, nrog ib tug ntse poob nyob rau hauv elasticity thiab tsis muaj peev xwm buffering. Ob leeg o thiab hardening yuav ua rau tus nqi mus tas li deformation ntawm lub ncoo kom dhau qhov kev txwv, ua rau nws nyuaj rau kev tswj xyuas qhov kev ruaj ntseg ntawm qhov ntsuas geometric qhov ntev hauv qhov chaw hloov.
Dab tsi tshwj xeeb tsim muaj nyob rau hauv cov qauv ntawm cov khoom tshwj xeeb hauv qab -rail pads rau qhov chaw hloov?
Cov ntaub qhwv tshwj xeeb rau cov chaw hloov pauv siv cov roj hmab ntau yam nrog cov roj zoo heev, xws li roj hmab nitrile thiab fluororubber, lossis roj- cov ntaub ntawv hloov kho polyurethane resistant. Cov tshuaj tiv thaiv roj thiab cov tshuaj tiv thaiv ntxiv yog ntxiv rau cov qauv los txhim kho cov khoom siv polymer rau cov roj stains. Nyob rau tib lub sijhawm, cov roj- tiv thaiv kev sib cais yog ntxiv rau hauv lub ncoo nto los tsim kev tiv thaiv lub cev thiab tiv thaiv cov roj stains los ntawm kev nkag mus rau sab hauv. Cov qauv tsim tshwj xeeb no tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm lub ncoo hauv cov roj-ib puag ncig cov pa paug mus rau 3-5 npaug ntawm cov pawm zoo tib yam.
Cov pawm zoo li qub puas tuaj yeem siv rau cov kab sib txawv - cov kab nrawm tuaj yeem siv ib ntus hauv cov roj- cov kab mob kis tau ntawm cov chaw hloov pauv?
Tsis pom zoo siv ib ntus. Cov pawm zoo li qub tsis muaj roj tshwj xeeb-tsim tiv taus thiab yuav ua tsis tau sai hauv cov roj-ib puag ncig. Txawm tias luv luv - siv lub sij hawm, o thiab deformation yuav tshwm sim nyob rau hauv ob peb lub lis piam, ua rau ntau dhau deviations nyob rau hauv hloov ntsuas thiab qib, cuam tshuam rau ib txwm hloov dua siab tshiab ntawm point machines. Qhov chaw hloov pauv yog ib feem tseem ceeb ntawm txoj kab nrog cov kev xav tau siab heev rau kev ua haujlwm ntawm lub ncoo, thiab kev hloov pauv ib ntus yuav ua rau muaj kev nyab xeeb zoo heev. Yog tias tsim nyog siv thaum muaj xwm txheej ceev, cov roj stains yuav tsum tau muab ntxuav kom raws sij hawm, thiab cov roj tshwj xeeb - cov ntaub thaiv npog rau cov keyboards yuav tsum tau hloov sai li sai tau.
Yuav ua li cas txiav txim sai sai seb lub ncoo tau ua tsis tiav vim roj stain corrosion ntawm -site?
Ua ntej, soj ntsuam cov tsos ntawm lub ncoo. Yog hais tias muaj ntim expansion, nplaum nto, tawg los yog darkening, nws qhia corrosion los ntawm cov roj stains. Nias lub ncoo ntawm tes; Yog hais tias nws zoo nkaus li mos thiab inelastic, los yog tawv thiab nkig, nws yog invalid. Ua ke nrog cov geometric dimension nrhiav pom ntawm qhov hloov chaw, yog tias txoj kev tsheb ciav hlau sib haum xeeb thiab ntsuas qhov sib txawv hauv qhov chaw tshuab taw qhia feem ntau tshaj qhov txwv thiab muaj cov roj stains hauv cheeb tsam, nws yog qhov muaj feem ntau tias lub ncoo tau ua tsis tiav vim cov roj tsis zoo. Tom qab nrhiav tau ib lub ncoo ua tsis tiav, nws yuav tsum tau hloov tam sim ntawd, thiab cov roj qhov chaw yuav tsum tau muab ntxuav kom tsis txhob muaj lub ncoo tshiab los ntawm corroded dua.
