Tsav los ntawm industrialization, valve castings txuas ntxiv qhib kev lag luam. Nrog rau txoj kev loj hlob ntawm valve manufacturing technology, daim ntawv thov teb ntawm valve castings kuj expanding. Txawm li cas los xij, vim qhov tshwj xeeb ntawm valve castings, hauv cov txheej txheem ntawm kev siv, ntau tus neeg yuav pom qhov blackening ntawm valve castings. Yog vim li cas?
Cov txheej txheem tsim tsis tsim nyog
Nyob rau hauv tus txheej txheem ntawm kev tu lub valve castings, yog hais tias cov neeg ua hauj lwm tsis ua kom zoo thaum lub sij hawm ntxuav los yog kev soj ntsuam xyuas, nws yuav ua rau pwm thiab blackening ntawm cov castings, accelerate tsim mildew, thiab cuam tshuam rau lub nto ntawm lub valve castings.
Cov nyhuv ntawm cov tshuaj ntxuav
Thaum tu cov castings, yog tias tus neeg saib xyuas xaiv tau muaj zog corrosive, tus neeg saib xyuas yuav muaj tshuaj lom neeg muaj zog nrog cov castings, thiab tseem tuaj yeem ua rau corrosion thiab oxidation ntawm cov castings, uas ua rau blackening ntawm lub valve castings.
Kev tu tsis raug ntawm cov castings
Qhov kev huv huv ntawm cov casting kuj cuam tshuam rau qhov gloss ntawm lub valve casting. Hauv kev tsim khoom tiag tiag, ntau lub hauv paus hauv paus tsis ua haujlwm tu thaum ua cov castings, los yog tsuas yog ntxuav nrog dej, uas tsis tuaj yeem ua tiav cov txiaj ntsig ntawm kev ntxuav ntawm qhov chaw castings. Tsis tas li ntawd xwb, yog tias muaj cov khoom corrosive xws li txiav cov kua thiab saponification kua los yog lwm yam stains tseem tshuav ntawm qhov chaw ntawm lub valve, nws tseem yuav ua kom cov pwm loj hlob thiab blackening ntawm cov casting.
Kev cuam tshuam ntawm ib puag ncig sab nraud
Kev cuam tshuam ntawm ib puag ncig sab nraud tsis tuaj yeem tsis quav ntsej. Tom qab ua tiav cov castings tiav lawm, kev tswj cov khoom lag luam yuav tsum nruj me ntsis tswj. Txhawm rau tiv thaiv pwm thiab oxidation ntawm valve castings, foundries yuav tsum xyuas kom meej tias qhov kub thiab av noo ntawm lub tsev khaws khoom yog nyob rau hauv qhov kev teev tseg. Qhov sib txawv ntawm qhov kub thiab av noo yuav ua rau lub valve castings dub sib txawv, uas yuav tsum tau soj ntsuam raws li qhov xwm txheej.
Lub blackening ntawm valve castings feem ntau tshwm sim los ntawm oxidation teeb meem, yog li tshwj xeeb yuav tsum tau them rau oxidation tiv thaiv nyob rau hauv cov txheej txheem ntau lawm. Cov ncauj lus kom ntxaws zuag qhia tag nrho yuav tsum tau ua tib zoo tsim nyob rau hauv cov nqe lus ntawm kev tu, tuag casting, cia thiab tsheb thauj mus los, thiaj li ua kom ntseeg tau zoo ntawm valve castings.
