Cov yam ntxwv ntawm cov rooj zaum carbide

Tungsten carbide rooj zaum, raws li lub hauv paus sealing Cheebtsam ntawm valve systems, nyob rau hauv ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub industrial teb vim lawv cov yam ntxwv kev ua tau zoo. Nrog nws cov khoom siv tshwj xeeb muaj pes tsawg leeg, tungsten carbide, lub rooj nthuav qhia tshwj xeeb ua kom muaj zog thiab yoog raws, ua rau nws yog thawj qhov kev xaiv rau ntau daim ntawv thov kev lag luam.

Ua ntej tshaj plaws, cov rooj zaum tungsten carbide paub txog lawv qhov hnyav thiab hnav tsis kam. Nyob rau hauv lub siab-siab, high-ceev ntws tawm ib puag ncig, cov khoom siv rooj zaum tsoos feem ntau nyuaj los tiv thaiv kev yaig thiab hnav mus ntev, thaum tungsten carbide tuaj yeem tiv taus qhov yaig ntawm cov mob hnyav vim nws lub cev zoo heev. Qhov no ua rau cov rooj zaum carbide zoo heev nyob rau hauv cov nqe lus ntawm kev ncua lub neej valve thiab txo cov nqi kho.

Qhov thib ob, kev tiv thaiv corrosion kuj yog qhov tseem ceeb ntawm lub rooj zaum carbide. Hauv cov tshuaj, roj av thiab lwm yam kev lag luam, qhov nruab nrab ntws hauv cov raj xa dej feem ntau yog corrosive, uas tso siab rau cov kev xav tau siab heev rau cov khoom siv lub rooj zaum valve. Nrog nws cov tshuaj lom neeg ruaj khov zoo heev, tungsten carbide tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv cov cheeb tsam hnyav no yam tsis muaj kev xeb thiab kev puas tsuaj, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm lub valve.

Tsis tas li ntawd, lub rooj zaum carbide muaj qhov ua haujlwm zoo rau qhov kub thiab txias. Hauv ntau cov txheej txheem kev lag luam, qhov kub ntawm qhov nruab nrab tuaj yeem nce siab heev, uas cuam tshuam qhov kub tsis kam ntawm cov khoom siv lub rooj zaum. Nrog nws cov ntsiab lus siab melting thiab siab thermal stability, cemented carbide tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias, tsis muaj deformation thiab tawg, ua kom lub cev ua haujlwm ntawm lub valve nyob rau hauv high-temperature ua hauj lwm tej yam kev mob.
