Txoj Haujlwm ntawm Rail Pad
Ib lub tsheb ciav hlau yog muab tso rau hauv nruab nrab ntawm txoj kev tsheb ciav hlau thiab lub hauv paus los yog pw tsaug zog. Nws yog nkag mus rau hauv txoj kev tsheb ciav hlau fastening system vim nws cov resilience los yog viscoelasticity, uas tuaj yeem ncua kev qaug zog tawg ntawm cov neeg pw tsaug zog: qhov kev nyuaj siab ntawm lub log lossis kev tsheb ciav hlau cuam tshuam, los ntawm ob qho tib si tsis tu ncua thiab tsis tu ncua, yog attenuated ua ntej nws mus txog lub pob zeb. Lub ncoo tseem kis tau lub log load hla ib cheeb tsam loj ntawm tus neeg pw tsaug zog thiab tswj txoj kev nruj ntawm txoj hlua khi. Lub ncoo haum haum tiv thaiv cov hlau- rau- kev sib cuag ua vaj tse thiab txo cov suab nrov xa mus rau ib puag ncig, uas yog vim li cas kev xaiv cov ntaub qhwv ntsej yog qhov kev txiav txim siab tsim, tsis yog kev xav tom qab.
Sib piv lub ncoo rau Rail Profile
Rail pads yog sib npaug rau UIC tus qauv rails, xws li UIC 54 thiab UIC 60, feem ntau los ntawm txoj kev tsheb ciav hlau qhov dav thiab qhov profile: lub ncoo ntev thiab dav yuav tsum ua raws li lub hauv paus rail geometry kom cov tsheb ciav hlau ko taw tau txhawb nqa sib npaug. Yog hais tias lub ncoo nqaim dhau lawm, lub tsheb ciav hlau puag ntug dais ntawm lub hauv paus phaj; yog tias nws dav dhau lawm, lub ncoo wrinkles ntawm cov npoo. Lub ncoo yog tom qab ntawd kho kom haum rau txoj kev tsheb nqaj hlau thauj khoom, ceev thiab daim ntawv thov los ntawm nws cov khoom siv thiab kev nruj, raws li tau piav qhia hauv UIC cov ntaub ntawv rau kev tsheb ciav hlau thiab cov txheej txheem fastening. Hauv kev xyaum, cov ntaub ntawv tshwj xeeb hais txog kev tsheb ciav hlau nws haum: 43 kg / m, 50 kg / m, 60 kg / m thiab 75 kg / m GB rails, 115 RE, UIC 54, UIC 60, thiab S49 yog cov npe siv ntau yam, nrog cov lej qauv xws li 43-7-7, 73-5-9, 73-5-10 60-10-17 thiab 60-12-17 qhia txog txoj kev tsheb ciav hlau thiab qhov ntev ntawm lub ncoo.
Kev xaiv cov khoom siv thiab tawv tawv
Rail pads yog tsim los ntawm cov roj hmab, EVA, TPEE thiab HDPE, thiab kev xaiv ntawm cov khoom siv tswj cov tawv tawv thiab damping tus cwj pwm ntawm cov fastening. Rubber pads muaj elasticity zoo thiab yog cov qauv xaiv rau cov kab tseem ceeb; EVA thiab TPEE pads yog siv rau qhov uas yuav tsum tau elasticity dua los yog zoo dua damping, thiab HDPE pads muab ib tug stiffer, hnav- kev xaiv resistant rau tej tshuab. Kev nruj yog xaiv raws li txoj kab ceev thiab qag load: siab - elasticity pads rau siab - ceev thiab hauv nroog kab, nruab nrab nruj rau cov kab hauv qab, thiab cov ntaub qhwv tawv rau hnyav - tsheb khiav. Tus tsim yuav tsum tau txiav txim siab seb lub ncoo puas muaj grooves: grooved pads hloov qhov chaw sib cuag thiab nruj thiab tau teev nyob rau qhov twg lub fastening system yuav tsum tau ib tug txhais load-deflection nkhaus. Cov qauv siv rau cov khoom siv ncoo suav nrog UIC 860 rau kev tsheb ciav hlau, TB/T 2626 rau cov ntaub qhwv cov txheej txheem, thiab EN 13481-3 rau kev ua kom ceev cov txheej txheem kev ua haujlwm.
Kev Xaiv thiab Kev Ua Haujlwm Kev Ua Haujlwm
Specification: engineers xaiv lub ncoo raws li txoj kev tsheb ciav hlau (UIC 50, 54, 60 lossis lub teb chaws profiles), kab ceev, qag load, thiab lub suab nrov thiab kev co damping.
Kev yuav khoom: cov chaw tsim khoom muab cov ntaub qhwv uas ua tau raws li cov qauv geometric thiab kev ua tau zoo, suav nrog kev nruj, tuab thiab zawj qauv, nrog rau daim ntawv pov thawj khoom siv rau txhua pawg.
Kev teeb tsa: lub ncoo yog muab tso rau ntawm lub hauv paus kev tsheb nqaj hlau thiab lub txaj pw lossis lub hauv paus, kuaj xyuas kom haum raws li txoj kev tsheb ciav hlau, thiab cov fasteners tau nruj kom lub ncoo yog loaded tusyees.

Cov ntaub qhwv yuav tsum muab khaws cia rau hauv qhov chaw huv, qhov cua, tiv thaiv los ntawm tshav ntuj ncaj qha, qhov chaw tshav kub thiab cov tshuaj reagents, thiab khaws cia kom deb ntawm cov roj, cov kuab tshuaj organic thiab lwm yam tshuaj. Kev cuam tshuam ncaj qha yog txwv tsis pub, vim tias UV, cua sov thiab roj ua kom cov roj hmab aging thiab hloov lub ncoo txhav ua ntej cov khoom puas tau mus txog.
Cov lus nug nquag
Q1: Dab tsi txiav txim siab lub ncoo haum rau UIC 60 rail?
Cov ko taw geometry ntawm txoj kev tsheb ciav hlau: lub ncoo ntev thiab dav yuav tsum ua raws li cov tsheb ciav hlau hauv paus profile yog li cov tsheb ciav hlau ko taw tau txais kev txhawb nqa sib npaug, nrog cov khoom siv thiab nruj xaiv rau txoj kab ceev, qag load thiab damping yuav tsum tau.
Q2: Vim li cas cov tsheb ciav hlau xav tau txhua?
Lawv attenuate dynamic log loads, ncua kev qaug zog tawg ntawm cov neeg pw tsaug zog, kis lub load hla ib cheeb tsam loj, tswj fastening nruj, thiab txo suab nrov thiab kev co.
Q3: Cov ntaub ntawv twg yog siv rau kev tsheb ciav hlau?
Rubber, EVA, TPEE thiab HDPE. Roj hmab muaj elasticity zoo, EVA thiab TPEE muab siab elasticity thiab damping, thiab HDPE muab ib tug nruj, hnav- kev xaiv resistant.
Q4: Dab tsi yog cov ntaub ntawv tus qauv zoo li 60-10-17 txhais li cas?
Lawv txheeb xyuas hom kev tsheb ciav hlau thiab qhov ntev ntawm lub ncoo, piv txwv li lub ncoo rau 60 kg / m rail nrog qhov ntev thiab tuab. Qhov tseeb code ua raws li cov ntaub ntawv kaw lus fastening.
Q5: Yuav ua li cas thiaj li yuav tsum tau khaws cia cov ntaub qhwv?
Nyob rau hauv ib qho chaw huv si, qhov cua, deb ntawm lub hnub ncaj qha, qhov chaw tshav kub, roj, cov kuab tshuaj organic thiab cov tshuaj reagents, nyob rau hauv qhov kub thiab txias ntawm -50 ° C mus rau 70 ° C.
