Yas cam khwb cia hlau manhole npog yog ib qho chaw tseem ceeb uas feem ntau pom nyob rau hauv txoj kev hauv nroog thiab cov chaw pej xeem.Muaj ntau txoj hauv kev uas lawv tuaj yeem siv tau thiab ntau qhov txiaj ntsig tseem ceeb ntawm cov manhole npog ua los ntawm cov hlau cam khwb cia ua rau lawv xaiv thawj zaug hauv thaj chaw ntawm manhole npog.
Cov txheej txheem ntau lawm ntawm manhole npog yog ib qho tseem ceeb heev, thiab cov yas cam khwb cia hlau manhole npog adopts txheej txheem casting.Cov txheej txheem no tsim cov cam khwb cia hlau manhole npog los ntawm nchuav molten cam khwb cia hlau rau hauv pwm thiab tshem tawm cov pwm tom qab nws txias thiab solidifies.Hauv qab no yog cov kauj ruam tseem ceeb hauv kev tsim khoom ntawm malleable cam khwb cia hlau manhole npog.
Ua ntej, ib tug casting pwm los ua lub casting yog npaj.Pwm feem ntau yog ua los ntawm cov xuab zeb tshwj xeeb uas tuaj yeem tiv taus qhov kub thiab txias thiab tswj qhov zoo ntawm cov khoom kawg.Tom qab ntawd, ncuav kua cam khwb cia hlau rau hauv pwm.Cov txheej txheem no yuav tsum muaj kev tswj xyuas qhov kub thiab txias kom paub meej qhov zoo thiab kev ncaj ncees ntawm cov casting.
Tom ntej no, lub cam khwb cia hlau yuav tsum txias thiab solidify.Qhov no tuaj yeem ua tiav los ntawm kev cia cov pwm zaum rau ib lub sijhawm ntawm qhov kub thiab txias.Lub sij hawm ua kom txias thiab kho yog nyob ntawm qhov loj ntawm lub manhole npog thiab cov khoom siv tshwj xeeb.Lub hom phiaj ntawm cov kauj ruam no yog los xyuas kom meej tias cov cam khwb cia hlau tau teem tag nrho thiab muaj qhov xav tau hardness thiab lub zog.
Thaum kawg, cov cam khwb cia hlau manhole npog yuav tsum tau muab tshem tawm ntawm pwm thiab ua tiav tom qab.Feem ntau, yuav muaj qee qhov seem ntawm lub manhole npog uas yuav tsum tau muab tshem tawm ua ntej kev kho saum npoo los yog kev kho cua sov los txhim kho nws cov huab cua tsis kam thiab corrosion kuj.Cov khoom kawg yuav tsum tau soj ntsuam xyuas kom zoo kom ua raws li cov qauv hauv lub tebchaws thiab cov cai.
Cov txheej txheem casting siv rau malleable cam khwb cia hlau manhole npog muaj ntau yam tseem ceeb.Nov yog ob peb yam zoo:
1. Durability: Malleable cam khwb cia hlau manhole npog muaj zoo heev durability thiab lub zog.Lawv muaj peev xwm tiv taus ntau yam kev ntxhov siab thiab kev tsheb khiav tsis tu ncua, ua rau lawv zoo tagnrho rau kev siv ntawm txoj kev thiab cov chaw pej xeem.
2. Kev nyab xeeb: Hom manhole npog no muaj kev nyab xeeb zoo heev.Lawv qhov kev ntxhib los mos thiab kev tsim qauv tuaj yeem muab cov txiaj ntsig zoo los tiv thaiv kev poob siab, txo qhov kev pheej hmoo ntawm kev raug mob rau cov neeg taug kev thiab tsheb vim kev swb.
3. Corrosion kuj: Yas cam khwb cia hlau manhole npog muaj zog corrosion tsis kam rau tshuaj thiab dej hauv ib puag ncig.Qhov no tso cai rau lawv ua tau zoo nyob rau hauv cov huab cua ntub thiab hnyav.
4. Kev lag luam: Piv nrog rau lwm cov ntaub ntawv, cov nqi tsim khoom ntawm cov yas cam khwb cia hlau manhole npog yog qhov tsawg.Lawv yog cov yooj yim los ua thiab kuj pheej yig hauv cov ntaub ntawv, ua rau lawv nyiam xaiv ntawm ntau lub nroog thiab pej xeem lub tsev.
5. Plasticity: Cov txheej txheem casting ntawm cov yas cam khwb cia hlau manhole npog tuaj yeem paub cov duab thiab cov qauv tsim.Qhov no muab cov chaw tsim khoom ntawm manhole npog nrog kev ywj pheej ntau dua los kho manhole npog hauv cov duab sib txawv thiab ntau thiab tsawg raws li cov kev xav tau tshwj xeeb.
Nyob rau hauv luv luv, yas cam khwb cia hlau manhole npog yog tsim los ntawm cov txheej txheem casting, uas muaj ntau yam zoo xws li durability, kev ruaj ntseg, corrosion kuj, kev lag luam thiab plasticity.Cov txiaj ntsig no ua rau cam khwb cia hlau manhole npog ib qho manhole npog xaiv hauv nroog thiab tau siv dav hauv ntau qhov chaw pej xeem.Txawm hais tias nws yog txoj kev lossis txoj kev taug kev, cov yas cam khwb cia hlau manhole npog tuaj yeem muab cov neeg siv kev paub zoo thiab kev nyab xeeb lav rau pej xeem.
