Qhov sib txawv ntawm Ductile Iron Manhole Cover thiab Composite Manhole Cover

Ua los ntawm ductile hlau raw khoom. Cov hlau molten raug kho spheroidizing ua ntej tuag-casting. Raws li cov khoom siv hlau, nws nta spheroidal graphite sab hauv, xa ntau dua toughness thiab lub zog dua li cov hlau cam khwb cia grey.

Nws feem ntau yog ua los ntawm cov khoom siv cob-raws li cov ntaub ntawv sib xyaw, muaj cov khoom siv tsis zoo, iav fiber ntau, quartz xuab zeb thiab cov muab tub lim. Kuj tseem muaj cov cement sib xyaw thiab cov yas sib xyaw. Raws li cov khoom siv tsis yog-nws yog xim hlau sib xyaw, nws yog tsim los ntawm compression molding thiab curing.

Iron Manhole CoverNws nta lub zog siab, zoo heev cuam tshuam tsis kam thiab dov tsis kam. Muab faib ua lub teeb, nruab nrab, hnyav thiab ntxiv -hnyav hom. Nws tuaj yeem nqa tau tsheb, tsheb thauj khoom thiab lub tshuab hluav taws xob, thiab yog qhov kev xaiv zoo tshaj plaws rau txoj kev loj hauv nroog, txoj kab nrawm thiab qhov hluav taws kub tawm.

Composite Manhole CoverCov khoom siv kuj yog nkig nrog lub peev xwm qis tshaj plaws. Nws tsuas yog tsim nyog rau kev taug kev, txoj siv sia ntsuab thiab tsis yog - txoj kab tsheb ciav hlau hauv thaj chaw nyob. Ntev - lub sij hawm dov los ntawm cov tsheb hnyav yuav yooj yim ua rau tawg lossis tawg. Nws yog txwv tsis pub siv rau hauv txoj kev loj.

High deg hardness muab zoo heev hnav tsis kam. Nws ua suab nrov los ntawm cov hlau cuam tshuam thaum dov los ntawm lub tsheb, thiab muaj qhov nruab nrab tiv thaiv - plam kev ua haujlwm rau hnub los nag.

Nruab nrab hnav tsis kam. Nws zoo toughness muab cov nyhuv cushioning rau kev ntsiag to. Kev cai los tiv thaiv- cov qauv nplawm tuaj yeem ua rau saum npoo kom zoo dua los tiv thaiv- plam kev ua haujlwm.

Txoj kev hauv nroog loj, txoj kab tsheb tsav tsheb, qhov hluav taws kub tawm, chaw ua si, chaw nres nkoj, chaw thauj khoom thiab kev nkag & tawm ntawm cov chaw nres tsheb hauv av, uas yog txhua qhov chaw uas muaj tsheb loj.

Txoj kev taug kev, chaw ua si, kev taug kev hauv tsev, txoj siv sia ntsuab, plazas, scenic chaw, tsis yog - thaj chaw tsheb tsav hauv cov zej zog thiab cov kav dej hauv av hauv tsev, xws li thaj chaw tsis muaj tsheb hnyav
