1.Qhov kev ua tau zoo ntawm kev ua haujlwm siab:
Centrifugal ductile hlau muaj cov ntsiab lus ntawm cov hlau thiab kev ua haujlwm ntawm cov hlau, yog li cov kav hlau hlau muaj kev ruaj ntseg zoo tshaj cov kav dej ua los ntawm lwm cov ntaub ntawv.Qhov tsim kev ua haujlwm siab yog ntau dua li cov kav dej ua los ntawm lwm cov ntaub ntawv, qhov kev nyab xeeb zoo nkauj yog qhov siab zoo nkauj, thiab qhov tuaj yeem tawg siab yog
peb zaug ntawm kev ua haujlwm siab.
2.Qhov kev ua tau zoo ntawm kev ua haujlwm siab:
Kev kub siab ua haujlwm tuaj yeem zam qhov yuav tsum tau ua ntawm cov yeeb nkab txaj thiab kev tiv thaiv npog, ua rau cov kav dej nteg rellable thiab kev lag luam.
3.Inner anti-corrosion txheej:
Sab hauv txheej ntawm cov yeeb nkab hlau yog centrifugally sprayed nrog cement mortar.Cov cement hauv ob sab phlu ua raws li tus txheej txheem thoob ntiaj teb ISO4179, ua kom cov mortar muaj zog thiab du.Cov txheej txheem lub cev yuav tsis poob los yog foul, thiab nws cov tuab yog txawm tias ua kom cov dej haus pauv los ntawm cov kav dej tau txais kev tiv thaiv zoo.
4. Txheej tiv thaiv:
Cov zinc txau ntawm cov kav hlau hlau tuaj yeem tiv thaiv cov kav dej kom zoo los ntawm cov nyhuv electrochemical ntawm zinc thiab hlau.Nrog lub siab chiorinated resin xim, cov kav dej yuav tau txais kev txhim kho kev tiv thaiv corrosion.Qhov chaw zinc txau ntawm txhua cov yeeb nkab tsis pub tsawg dua 130g / m², thiab ua raws li ISO8179 tus qauv.Peb tuaj yeem ua kom cov zinc txau tuab lossis txau zinc & aluminium alloy txheej raws li cov neeg siv khoom xav tau.
Nta
Ductile hlau yeeb nkab yog ib hom cam khwb cia hlau yeeb nkab.Nyob rau hauv cov nqe lus ntawm zoo, spheroidization theem ntawm cam khwb cia hlau kav yuav tsum tau tswj nyob rau hauv 1-3 theem (spheroidization tus nqi> 80%), yog li txhim kho cov neeg kho tshuab zog ntawm cov khoom nws tus kheej, muaj cov ntsiab lus ntawm hlau thiab cov khoom ntawm hlau. .Lub annealed ductile hlau yeeb nkab muaj ib tug metallographic qauv ntawm ferrite nrog ib tug me me ntawm pearlite, uas muaj zoo mechanical zog, zoo heev anti-corrosion kev kawm, zoo ductility, zoo sealing nyhuv, yooj yim installation, thiab yog tsuas yog siv rau dej, kis tau tus mob. , roj tsheb thauj mus los, thiab lwm yam hauv kev lag luam hauv nroog thiab kev lag luam.
Muaj qee tus nqi ntawm cov duab puab kheej kheej faib rau ntawm matrix ntawm ferrite thiab pearlite.Nyob ntawm lub nominal txoj kab uas hla thiab yuav tsum tau rau elongation, qhov kev faib ua feem ntawm ferrite thiab pearlite nyob rau hauv lub matrix qauv txawv.Qhov kev faib ua feem ntawm pearlite nyob rau hauv me me diameters feem ntau tsis ntau tshaj 20%, thaum uas nyob rau hauv loj diameters feem ntau tswj nyob ib ncig ntawm 25%.
Daim ntawv thov
Cov kav hlau kav dej muaj nyob rau hauv ntau txoj kab uas hla ntawm 80mm mus rau 1600mm thiab tsim nyog rau ob qho tib si kev xa dej thiab kev xa tawm (raws li BS EN 545) thiab cov kav dej phwj tuaj (raws li BS EN 598).Ductile hlau kav yog yooj yim rau kev sib koom ua ke. , tuaj yeem muab tso rau hauv txhua qhov huab cua thiab feem ntau tsis tas yuav tsum tau xaiv cov khoom siv rov qab.Nws qhov kev nyab xeeb siab thiab muaj peev xwm ua kom haum rau hauv av txav ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv ntau yam.
