Raws li cov khoom siv tseem ceeb rau kev ntsuas dej pabcuam thiab kev tswj hwm, cov khoom siv uas cov khoom siv uas cuam tshuam ncaj qha, lub neej kev hloov kho, thiab ib puag ncig kev yoog. Nrog rau kev txhim kho kev txawj ntse ntawm cov qauv dej kev lag luam thiab nce cov qauv dej zoo, kev xaiv ntawm science dej tau dhau los ua qhov tseem ceeb ntawm kev lag luam.
Cov khoom siv ib txwm muaj hlau metric me ntsis siv brass thau khoom ua rau lawv cov khoom tseem ceeb, vim nws cov khoom siv corrosion tsis kam thiab ua kom tiav, ua kom muaj kev ruaj khov ntev. Txawm li cas los xij, muaj peev xwm muaj cov hmoov txhuas hauv brass tau hais txog kev txwv ib puag ncig, ua rau cov chaw tsim khoom lossis cov khoom siv dawb dawb. Nyob rau hauv xyoo tsis ntev los no, engineering plastics xws li hlau hlau thiab txhawb nylon tau dhau los ua cov neeg tau txais txiaj ntsig, kev tiv thaiv corron tau dhau los ua kev lag luam me me, thiab qis - tus nqi. Cov ntaub ntawv no tau txhim kho kev ua siab ntev rau cov dej acidic thiab alkaline, ua rau lawv haum rau hauv thaj chaw deb hauv thaj chaw deb nroog lossis chaw nyob deb nroog.
Sawv ntawm cov dej khov nab kuab meters tau tso cov kev xav tau ntau dua ntawm cov ntaub ntawv. Forting cov hluav taws xob hluav taws xob yuav tsum tau siab- kev sib xyaw ua ke nrog cov ntaub pua chaw thiab sib xyaw ua ke ntev}. Piv txwv li, hloov polycarbonate lossis iav fiber ntau txhawb nqa nylon feem ntau siv rau cov xwm txheej thiab kev sib npaug. Kev txaus siab sab hauv - los ntawm cov khoom siv uas tau nkag mus rau hauv cov dej uas tsis muaj hlau los tiv thaiv cov hlau ion paug. Ntub {{{} Hom dej me me tau siv tooj liab alloy tshaj rau lawv cov tsheb ciav hlau, kom pom tseeb qhov tseeb thaum txo cov hnav.
Kev xaiv cov khoom siv kuj yuav tsum tau ua kom haum rau cov xwm txheej tshwj xeeb. Rau cov dej faus rau hauv cov dej me, cov ntawv av yuav tsum txiav txim siab, thiab epoxy cob cov txheej txheem feem ntau ntxiv rau kev tiv thaiv sab nraud. Txog siab {- sov qhov chaw, thermal ruaj khov yog qhov yuav tsum tau los tiv thaiv kev nthuav dav thiab deformation uas yuav ua rau lub ntsej muag tsis ua haujlwm. Ob leeg thoob ntiaj teb tus qauv ISO 4064 thiab tus qauv hauv tebchaws GB / T 778 kom meej meej los ntawm kev ua kom muaj tsawg kawg tsib xyoos nyob rau hauv kev ntsuas siab thiab dej tsis zoo.
Nyob rau yav tom ntej, nrog rau kev txhim kho cov khoom siv tshiab thev naus laus zis, lub teeb yuag, thiab anti {{} fouling plauv cov khoom yuav txuas ntxiv ua kom dej 'meter. Qhov kev lag luam yuav tsum tau tawm tsam kev sib npaug ntawm tus nqi tswj tau thiab ntev- sij hawm kev ntseeg tau. Yuav tsum tau xeem cov qauv yuav tsum tau siv los txheeb xyuas qhov siab {4 4}} Cov khoom siv zoo haum rau kev txhim kho cov dej tswj dej ntse. Cov ntawv thov kev tshawb fawb ntawm cov ntaub ntawv tsis yog tsuas yog cuam tshuam nrog cov khoom lag luam nws tus kheej, tab sis kuj tseem ceeb lav rau kev tswj cov dej muaj txiaj ntsig.
