Vim li cas lub luj tshib ceramic yog hnav-resistant dua li cov luj tshib hlau?
Lub luj tshib, raws li cov nodes uas cov ntaub ntawv hloov cov kev taw qhia nyob rau hauv pipeline tsheb thauj mus los, yog scoured los ntawm cov ntaub ntawv rau lub sij hawm ntev thiab yog hnyav hnyav nyob rau hauv cov kav dej. Kev pabcuam lub neej ntawm lub luj tshib feem ntau txiav txim siab txog kev pabcuam lub neej thiab kev tu ntau zaus ntawm tag nrho cov tsheb thauj mus los. Yog li, dab tsi yog qhov tseem ceeb uas cuam tshuam rau lub neej kev pabcuam ntawm lub luj tshib? Vim li cas lub luj tshib ceramic yog hnav-resistant dua li cov luj tshib hlau?
Raws li kev soj ntsuam kev tshawb fawb thiab kev siv tswv yim tsom xam, muaj ob lub ntsiab tseem ceeb cuam tshuam rau lub neej kev pab cuam ntawm lub luj tshib - cov khoom siv ntawm lub luj tshib thiab ib puag ncig sab nraud.
1. Cov khoom siv hauv lub luj tshib: Lub luj tshib feem ntau yog ua los ntawm cov khoom siv hlau, xws li cov khoom siv chromium cam khwb cia hlau, siab manganese steel, thiab lwm yam, tab sis cov khoom siv hlau tsis muaj zog, thiab feem ntau ntawm lawv yog qhov nyuaj tshaj HRC60. Tom qab qhov hardness tshaj HRC60, nws yuav raug nqi ntau dua los ua kom cov hardness ntxiv. Ncaj nce, uas ua rau muaj kev txwv tsis pub hnav tsis kam ntawm lub luj tshib hlau thiab lub neej ua haujlwm luv. Nyob rau hauv kev sib piv, lub hardness ntawm hnav-resistant ceramics nrog alumina raws li lub ntsiab raw khoom tau yooj yim mus txog HRA90, nrog zoo heev hnav tsis kam, thiab cov kev pab cuam lub neej ntawm hnav-resistant ceramic luj tshib tuaj yeem ncav cuag ob peb zaug lossis kaum zaus ntawm lub luj tshib.
2. Sab nraud ib puag ncig: Qhov chaw ua haujlwm ntawm lub luj tshib kuj tseem yuav muaj kev cuam tshuam zoo rau nws lub neej kev pab cuam, xws li kub kub, kua qaub thiab alkali corrosion, thiab qhov chaw ntub dej. Lub luj tshib hlau nthuav dav nrog cua sov thiab cog lus nrog txias ntawm qhov kub thiab txias, uas yooj yim rau kev cuam tshuam cov kav dej. Tsis tas li ntawd, cov khoom siv tshuaj lom neeg ntawm cov hlau yog nquag, thiab nws yooj yim rau corroded los ntawm acid thiab alkali. Nws yuav xeb hauv qhov chaw ntub dej, ua rau muaj kev hnav ntau ntxiv. Nyob rau hauv kev sib piv, hnav-resistant ceramic luj tshib yog resistant rau kub kub, muaj zog tshuaj zog, yog resistant rau acid thiab alkali corrosion, thiab tsis ntshai ntawm ya raws.
Raws li ob qho laj thawj saum toj no, kev hnav tsis kam thiab kev pab cuam lub neej ntawm hnav-resistant ceramic luj tshib yog qhov zoo tshaj rau lub luj tshib hlau. Tsis tas li ntawd, nws yog lub teeb hauv qhov hnyav, yooj yim thauj, yooj yim khaws cia, yooj yim rau nruab thiab hloov, txuag cov neeg siv khoom thiab cov khoom siv, thiab muaj cov khoom me me ntawm qhov system.
