Kev ua tau zoo ntawm cov kav hlau kav hlau nyob hauv qis - qhov kub thiab txias

                                                        Yuav ua li cas ductile hlau raj ua haujlwm?

      Hauv ntau lub nroog engineering thiab kev lag luam kev lag luam, cov kav hlau kav hlau tau txais txiaj ntsig zoo rau lawv cov kev ua tau zoo thiab txhim khu kev qha zoo. Yog li ua li cas cov kav dej hlau ua tau zoo nyob rau hauv qis - qhov chaw kub?

01Qhov zoo ntawm Ductile Iron Pipes

Cov kav dej hlau yog tsim los ntawm cov hlau, carbon, thiab silicon los ntawm cov txheej txheem tshwj xeeb casting. Lawv muab ntau qhov zoo tshaj plaws:

01

Siab zog thiab toughness

 

Cov kav dej hlau tsis yog tsuas yog muaj lub zog tensile siab xwb, tab sis kuj zoo toughness, ua rau lawv tswj kev ncaj ncees thaum raug lub siab loj thiab cuam tshuam.

02

Muaj zog corrosion kuj

 

Nws txoj kev tiv thaiv corrosion zoo ua rau cov kav hlau txuas tau los tiv thaiv kev yaig los ntawm kev tshaj tawm xws li av thiab dej, txuas ntxiv lawv lub neej kev pab cuam. Nyob rau hauv qis - qhov kub thiab txias, tus nqi corrosion qeeb qeeb, kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov kav dej.

03

Zoo sealing kev ua tau zoo

 

Lub T- hom hloov pauv tau siv lub nplhaib roj hmab rau kev sib khi, uas tiv thaiv dej kom zoo thiab ua kom muaj kev nyab xeeb ntawm cov kav dej.

Ntawm qhov kub thiab txias, cov khoom siv hluav taws xob ntawm cov kav hlau kav hlau yuav hloov me ntsis,tab sis lawv qhov kev ua tau zoo yuav tsis txo qis:

1. Kev hloov ntawm toughness

Tsis tshua muaj kub txo cov toughness thiab nce lub brittleness ntawm ductile hlau kav, tab sis ductile hlau kav lawv tus kheej muaj ib tug tej yam kev mob ntawm toughness thiab ductility, yog li lawv tseem muaj peev xwm tiv tau ib tug tej yam kev nyuaj siab ntawm tsawg kub.

2. Hloov lub zog thiab hardness

Hauv low- qhov kub thiab txias ib puag ncig, lub zog thiab hardness ntawm cov kav hlau txuas ntxiv, thiab lawv cov kev ua haujlwm siab kuj tseem txhim kho.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kub qis yuav ua rau cov roj hmab ntsaws ruaj ruaj kom nthuav dav thiab cog lus. Kev teeb tsa tsis raug tuaj yeem ua rau muaj qhov khoob ntawm cov yeeb nkab txuas, ua rau cov dej xau. Yog li ntawd, tshwj xeeb yuav tsum tau them nyiaj rau txoj kev teeb tsa thaum txhim kho cov kav hlau txuas hauv qhov qis - qhov kub thiab txias.

Raws li cov khoom tseem ceeb hauv cov yeeb nkab hlau txuas, kev ua haujlwm ntawm cov roj hmab nplhaib ncaj qha cuam tshuam rau cov yeeb nkab sealing kev ua tau zoo. Nyob rau hauv qhov tsis tshua muaj siab - qhov kub thiab txias, nws raug nquahu kom xaiv cov nplhaib roj hmab nrog kev ua tau zoo thiab elasticity kom ntseeg tau tias muaj kev sib khi zoo ntawm cov yeeb nkab sib txuas.

 

 

 

Jintai Hongye cov kav hlau txuas tau ua tau zoo tshwj xeeb hauv cov haujlwm thoob plaws ntau thaj chaw txias, ua kom pom tseeb tias lawv qhov kev ua tau zoo tshaj plaws hauv qhov qis - qhov kub thiab txias. Piv txwv li, nyob rau hauv cheeb tsam xws li Heilongjiang, Xinjiang, thiab Inner Mongolia, cov kav hlau kav dej tsis pom muaj qhov tshwm sim ntawm kev tawg lossis tawg ntawm qhov kub thiab txias li -30 degrees Celsius, ua kom cov kav dej ruaj khov thiab lav cov dej zoo rau cov neeg nyob hauv.

Cov kav hlau kav dej tau pom qhov ua tau zoo tshaj plaws thiab qhov zoo hauv kev siv cov cheeb tsam txias, muab cov lus qhia siv tau rau kev xaiv cov khoom hauv engineering tej yaam num nyob rau hauv qis - kub.
