Rail padsyog siab -cov khoom ua tau zoo nruab nrab ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog uas ua haujlwm rau ntau yam haujlwm tseem ceeb. Lawv tau tsim los txo cov kev ntxhov siab los ntawm cov tsheb ciav hlau mus ncig ntawm ntau qhov nrawm thaum ua kom ntseeg tau tias kev sib tw khiav tau zoo. Ua los ntawm ntau yam ntaub ntawv, rail pads yog engineered los tiv thaiv hnyav loads thiab txawv ib puag ncig tej yam kev mob, ua rau lawv ib tug tseem ceeb nam ntawm kev tsheb ciav hlau tu.
Yuav ua li cas railroad pads tsim?
Railroad pads yog tsim los ntawm thawj zaug sib xyaw roj hmab / polymer compounds nrog additives, ces shaping lawv los ntawm siab -pressure molding (txhaj tshuaj los yog compression), ua raws li ib tug tseem ceeb vulcanization (kho) txheej txheem nrog cua sov thiab siab rau lub zog, thiab thaum kawg trimming thiab zoo- xyuas kom meej elastic qhov ntev thiab kev ua tau zoo, ensuring loads.
Khoom siv sib xyaw:
- Cov ntaub ntawv nyoos xws li cov roj hmab ntuj, SBR, lossis cov thermoplastic elastomers (TPEs) yog sib xyaw nrog cov khoom siv ntxiv (carbon dub, silica), cov tshuaj tua kab mob (sulfur), antioxidants, thiab cov yas yas.
- Qhov sib tov no yog ua tiav hauv cov khoom sib xyaw lossis yob mills kom ua tiav cov khoom tshwj xeeb xws li lub zog tensile, hnav tsis kam, thiab elasticity.
Moulding:
- Txhaj Molding: Cov khoom siv sib xyaw yog rhuab, txhaj rau hauv siab rau hauv cov pwm zoo, thiab tom qab ntawd txias.
- Compression Molding: Cov roj hmab sib xyaw yog muab tso ncaj qha rau hauv cov pwm kab noj hniav thiab compressed.
- Cov txheej txheem no tsim cov ntaub qhwv lub hauv paus, nrog rau cov yam ntxwv zoo li plua plav tiab lossis grooves.
Vulcanization (Curing):
- Cov ntaub qhwv molded yog raug rau qhov kub thiab txias.
- Cov kauj ruam tseem ceeb no hla- txuas cov saw hlau polymer, tsim kom muaj kev ruaj khov, elastic network uas muab lub ncoo nws cov kav ntev, ua kom muaj zog, thiab qaug zog.
Tiav & Trimming:
Tom qab kho, cov khoom siv ntau dhau (flash) raug tshem tawm, feem ntau siv dej- dav hlau txiav los yog lwm yam cuab yeej precision, kom ua tau raws li qhov ntev ntev.
Kev Tswj Xyuas Zoo:
Cov ntaub qhwv tiav tau raug kuaj nruj kom nruj, lub zog, elasticity, thiab qhov tseeb qhov tseeb
Kev ua hauj lwm hauv paus ntsiab lus ntawm railway pad
Railway pads ua hauj lwm raws li elastic cushions nruab nrab ntawm txoj kev tsheb ciav hlau thiab pw tsaug zog, absorbing shocks, faib lub log hnyav loads nyob rau hauv ib cheeb tsam loj, thiab txo cov suab nrov thiab kev co. Los ntawm kev muab elasticity, lawv tiv thaiv cov neeg pw tsaug zog los ntawm kev puas tsuaj thiab qaug zog, ua kom lub neej ntev, thiab txhim kho cov neeg caij tsheb kev nplij siab los ntawm kev dampening siab - zaus vibrations, ua ib qho tseem ceeb tsis nyob rau hauv lub tsheb ciav hlau fastening system.
Raws li ib tug kws tshaj lij rail fastener chaw tsim tshuaj paus, GNEE RAIL tuaj yeem tsim ntau hom roj hmab rail pads nrog cov ntaub ntawv sib txawv, xws li roj hmab ntuj, EVA, HDPE thiab lwm yam. Nyob rau hauv railway fastening system, roj hmab rail pads feem ntau ntsia nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb railway sleepers.
