Kev paub txog kev lag luam tooj liab: qhov zoo thiab qhov tsis zoo ntawm cov raj tooj liab
Qhov zoo thiab qhov tsis zoo ntawm cov raj tooj liab. Cov raj tooj liab yog ib hom ntawm cov hlau tsis muaj hlau, uas yog nias thiab kos cov raj seamless. Cov raj tooj liab muaj cov thermal conductivity zoo, thiab muaj zog thiab corrosion-resistant. Lawv yuav tsis tawg thaum lub ambient kub tsis tshua muaj, ua rau lawv xaiv thawj zaug rau cov neeg cog lus niaj hnub los txhim kho cov kav dej, cua sov thiab cua txias kav hauv txhua lub tsev lag luam.
Kev siv cov raj tooj liab
Cov raj tooj liab feem ntau yog siv rau hauv cov khoom siv hluav taws xob sib pauv, thiab tseem tuaj yeem siv rau hauv cov kav dej kub qis hauv cov khoom siv oxygen. Qee lub raj tooj liab nyias tuaj yeem siv los thauj qee cov kua dej uas muaj zog, thiab tseem tuaj yeem siv los ua cov raj ntsuas siab hauv cov twj paj nruag; Tsis tas li ntawd, cov kav dej tooj liab kuj muaj zog, tsis zoo li lwm cov hlau uas yooj yim corroded, yog li tam sim no ntau cov kav dej thiab cov kav dej tub yees siv hauv tsev yuav xaiv siv cov raj tooj liab.
Qhov zoo ntawm cov raj tooj liab
1. Durable: Cov khoom siv tshuaj lom neeg ntawm tooj liab yog qhov ruaj khov, thiab nws ua ke nrog cov yam ntxwv ntawm kev ua haujlwm txias, kub tsis kam, siab tsis kam, corrosion kuj thiab hluav taws kub, thiab tuaj yeem siv tau ntev hauv ntau qhov chaw.
2. Muaj kev nyab xeeb thiab txhim khu kev qha: cov raj tooj liab sib xyaw ua ke zoo ntawm cov kav hlau hlau thiab cov kav hlau tsis yog hlau. Nws yog ib qho nyuaj tshaj li cov kav dej yas thiab muaj lub zog siab ntawm cov hlau dav dav (lub zog ntawm cov kav dej txias txias yog sib npaug rau cov kav hlau steel nrog tib lub phab ntsa tuab); Nws yog qhov yooj yim rau khoov dua li cov hlau dav dav, muaj qhov zoo toughness thiab siab ductility, thiab muaj kev co zoo heev, cuam tshuam tsis kam thiab Frost heave kuj.
3. Kev tu cev thiab kev noj qab haus huv: ntau yam tshuaj lom neeg xws li kev hloov kho, cov khoom siv ntxiv, thiab cov khoom siv ntxiv ntawm cov kav dej yas hauv cov kav tooj liab.
4. Kev sib txuas ntawm cov kav dej tooj liab muaj zog: cov kav dej tooj liab txuas nrog cov khoom siv tooj liab, thiab kev sib txuas yog muaj zog.
5. Tus nqi ntawm cov kav dej tooj liab yog kev lag luam. Ntau cov ntaub ntawv muaj peev xwm ib txwm tau txais kev cawmdim hauv cov txheej txheem ntawm kev txhim kho cov kav dej tooj liab. Cov kav dej tooj liab yog qhov yooj yim heev rau kev ua thiab tsim khoom. Cov kav dej tooj liab yog lub teeb hauv qhov hnyav. Piv nrog rau lwm cov ferrous hlau threaded kav nrog tib txoj kab uas hla, tooj liab kav tsis tas yuav tuab li ferrous hlau. Tus nqi thauj mus los ntawm kev txhim kho cov kav dej tooj liab yog qis dua, thiab nws yooj yim heev rau kev tswj xyuas. Tooj liab kuj muaj cov yam ntxwv ntawm kev hloov nws cov duab ntawm lub siab nyiam, yog li cov kav dej tooj liab tuaj yeem khoov lossis deformed thiab yooj yim rau kev txuas. Txij li thaum tooj liab tuaj yeem deformed ntawm qhov xav tau, cov raj tooj liab kuj tau ua rau hauv cov yeeb nkab tooj liab. tooj liab kuj yog corrosion-resistant thiab environmentally friendly. Nws tau hais tias archaeologists tau tshawb pom cov kav dej tooj liab nrog keeb kwm ntawm ntau txhiab xyoo hauv Egyptian pyramids, thiab cov dej ntws tawm ntawm cov dej tooj liab tseem tuaj yeem siv tau. Yog li ntawd, qhov zoo ntawm cov raj tooj liab tuaj yeem raug sau tseg raws li kev lag luam kev lag luam, kev sib txuas yooj yim, kev nyab xeeb, thiab kev tiv thaiv corrosion.
6. Qhov zoo ntawm cov raj tooj liab:
(1) Qhov zoo ntawm cov hlau tsis muaj pa oxygen: cov raj tsis muaj pa oxygen muaj cov purity siab, zoo heev hluav taws xob conductivity, thermal conductivity, txias thiab kub ua hauj lwm zoo thiab vuam zoo, thiab tsis muaj "hydrogen kab mob" los yog tsawg heev "hydrogen kab mob" .
(2) Qhov zoo ntawm cov raj tooj liab ntshiab:
① Qhov zoo ntawm T2 tooj liab raj: muaj cov kab tsis huv thiab cov pa oxygen, muaj hluav taws xob zoo, thermal conductivity, corrosion kuj thiab kev ua haujlwm zoo.
② Qhov zoo ntawm T3 cov raj tooj liab: muaj cov pa ntau dua thiab cov impurities, muaj hluav taws xob zoo, thermal conductivity, corrosion kuj thiab kev ua haujlwm.
(3) Qhov zoo ntawm phosphorus deoxidized tooj liab raj: kev ua haujlwm zoo, kev ua haujlwm vuam zoo, kev ua haujlwm txias txias zoo, feem ntau tsis muaj "kab mob hydrogen", tuaj yeem siv rau hauv qhov chaw txo qis, tab sis tsis tuaj yeem ua tiav thiab siv rau hauv qhov chaw oxidizing.
