Kev lag luam tshuaj lom neeg yog kev lag luam nrog ib puag ncig hnyav, khoom siv xws li pipelines thiab li qub ua lub luag haujlwm tseem ceeb hauv kev lag luam tshiab. Li qub yog cov nyom ib puag ncig hauv conveline pipelines xws li hmoov, granules, thiab slidries, thiab feem ntau nquag rau valve yeeb kev hnav thiab tsis ua haujlwm. Yog li ntawd, peb yuav tsum siv cov ntoo muaj zog-resistant, corrosion-resistant cov khoom siv ntawm lub neej raw ntawm lub neej valve, yog li ntawd lub valve muaj kev pab cuam lub neej ntev dua, thiab cem kev zoo tshaj plaws. Zhuzhou Chuzegrui cemented carbide Co., Ltd. yuav qhia rau Carbide yuav tsum xaiv raws li cov khoom siv rau cov khoom siv rau cov khoom siv tshuaj lom neeg.
Nyob rau hauv cov tshuaj lom neeg ntsuas hluav taws xob, av thiab ib feem ntawm cov roj av sib xyaw ua ke thiab ua kom muaj kev sib xyaw kom zoo dua thiab ua kom muaj kev puas tsuaj rau kev puas tsuaj thiab ua rau muaj kev puas tsuaj ntawm lub valve. Yog li ntawd, nyob rau hauv kev ua haujlwm hnyav xws li cov hmoov tsheb sib tsoo, hnav tsis kam yog qhov ntsuas kev ua tau zoo heev ntawm lub valve.
Peb xaiv cov subined tungsten carbide li cov khoom sivua valve, uas tsis tsuas muaj lub zog siab, tab sis kuj tseem muaj lwm cov ntaub ntawv, uas tuaj yeem txo qhov sib txhuam ntawm qhov chaw sib tiv tauj thiab ua kom zoo txo cov haujlwm ua haujlwm
Infteral sintered tungsten carbide yog ua los ntawm cov cua sov sib tov ntawm tungsten thiab carbon ntawm qhov kub, feem ntau ntawm cov tungsten carbide muaj siab tawv,yog li nws tsis yooj yim rau decompose ntawm qhov kub thiab txias, thiabkujmuaj cov oxidation zoo tsis kam.
Nyob rau hauv cov thee roj av lub valve, lub rooj valve disc thiab valve lub rooj yog ua los ntawm kev sib xyaw tungsten carbide, thiab lub valve muaj cov txiaj ntsig zoo hauv qab no:
1,Siab tawv. Hardness> 80hrc, uas tuaj yeem tiv thaiv cov kev tawm tsam siab ntawm Multiphase Media Media, pulverized thee, silica fume, thiab lwm yam. Silica fume, thiab lwm yam. Silica fume, thiab lwm yam
2,Kev kub siab kuj. Nws tuaj yeem ua haujlwm ntawm750 ° C Kev kub siab ntev rau lub sijhawm ntev, thiab nws lub zog thiab thermal expansion tsis txwv los ntawm qhov kub thiab txias xws li cov tshuaj lom neeg kev lag luam.
3,Kev siab siab kuj. Lub tsheb ciav hlau tawg ntawm lub zog ntawm tag nrho sintered tungsten carbidetauncav cuag 4000mpa, uas yog ntau tshaj 10 zaugof Cov hlau sib xyaw.
4,Corrosion-resistanceCov. Tag nrho cov sintered cemented carbide yog chemically ruaj khov, insoluble ruaj khov, thiab tsis sib tham nrog hydrochloric acid thiab sulfuricic acid thiab sulfuricic acid thiab sulfuricic acid thiab sulfuricic acid
5,Akev khawb dej rtus esistanceCov. Cov yam ntxwv ntawm Hardness thiab Siab Ruaj Ntseg ntawm cov cemented mem vim kev tiv thaiv kev ua tau zoo ntawm cov khoom sib khi.
6,ECov Dej Rosion Resistance.
Nyob rau hauv dav dav, tus tseem ceeb sterintered tungsten carbide cementance tuaj yeem txhim kho cov kev sib txhuam, thiab ua kom muaj zog, thiab siv tau ntau yam ntawm lub valve, thiab txuas ntxiv lub neej ua haujlwm ntawm lub valve.
Zhuzhou Chuzegrui cemented carbide Co., Ltd. HEEV HIGHLE DUA-RESISTORS THIAB KEV LAWM RAUG KEV UA HAUJ LWM RAU COV NTSHAV TSAV TSHUAJ.
