A rail ncoo, tseem hu ua rail roj hmab phaj, yog tsim los ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane lev, uas yog interposed ntawm steel rails thiab khi sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Daim ntawv tag nrho ntawm GRP hauv kev tsheb ciav hlau yog dab tsi?
Grooved Rubber Sole Plate (GRSP) yog muab tso rau ntawm Rail thiab pw tsaug zog. Nws muab cov nyhuv cushioning thiab tiv thaiv kev puas tsuaj rau cov neeg pw tsaug zog. Muaj ntau hom Grooved Rubber Sole Phaj rau ntau hom sleepers thiab kuj txawv rau Turnout, Steel channel sleepers, Guard rail feem, thiab lwm yam.
Daim ntawv qhia tag nrho ntawm Cgrsp hauv kev tsheb ciav hlau yog dab tsi?
Railway pads yog cov ntaub ntawv cushioning nyob nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog kom nqus tau cov kev vibrations, txo cov suab nrov, thiab tiv thaiv cov qauv khiav. Composite grooved ib leeg daim hlau (Cgrsp) txhim khu kev faib khoom thiab taug qab kev ruaj ntseg.
Cov ntaub ntawv dab tsi yog siv rau hauv cov ntawv sib xyaw grooved ib leeg?
Lawv yog tsim los ntawm cov qib siab -cov khoom siv roj hmab zoo uas muaj cov kav ntev, elasticity, thiab tiv taus huab cua thiab kev ntxhov siab.

Qhov txawv ntawm CGRSP thiab GRSP yog dab tsi?
Qhov txawv yog tias GRSP (Grooved Rubber Sole Plate) yog cov khoom siv dav dav rau cov roj hmab hauv qab txoj kev tsheb ciav hlau, thaum CGRSP (Composite Grooved Rubber Sole Phaj) yog ib qho tshwj xeeb, qib siab ntawm GRSP ua los ntawm ob txheej sib txuas ntawm cov roj hmab sib txawv, muab cov cushioning thiab elasticity zoo dua piv rau ib leeg - siv rau kev poob siab, tshwj xeeb tshaj yog rau kev poob siab, thiab GRSP. nkhaus. Qhov tseem ceeb, CGRSP yog GRSP, tab sis nrog kev txhim kho kev tsim kho kom zoo dua qub.
GRSP (Grooved Rubber Sole Phaj) (General)
- Muaj nuj nqi: Muab tso rau hauv nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog (kwv yees) los muab cov cushioning, hluav taws xob rwb thaiv tsev, thiab tiv thaiv kev pw tsaug zog.
- Khoom siv: Feem ntau ua los ntawm ib hom roj hmab sib xyaw.
- Daim Ntawv Thov: Siv thoob plaws ntau hom kev taug qab, suav nrog cov ntoo thiab pob zeb pw tsaug zog.
CGRSP (Composite Grooved Rubber Sole Phaj) (Tshwj xeeb)
- Muaj nuj nqi: Muab kev txhim kho kev co dampening thiab kev poob siab vim nws cov txheej txheem txheej.
- Khoom siv: Muaj ob txheej roj hmab sib txawv (txheej txheej saum toj kawg nkaus rau txoj kev tsheb ciav hlau, softer hauv qab txheej rau cov neeg pw tsaug zog) integrally vulcanized.
- Daim ntawv thov: Feem ntau siv rau ntawm cov nkhaus nkhaus thiab dav dav PSC (Prestressed Concrete) pw tsaug zog, muab kev ua tau zoo dua thiab siv tau ntev.
