Kev Kho Thiab Kev Siv Brown Corundum Ntawm Stainless Hlau Nto
Stainless hlau nto kho thiab abrasive xav tau
1. Tsis muaj casting steel nto kev kho mob
(1) Nto huv si P1, nto tu qib Sa2.5 (2) roughness nruab nrab ntawm 40-75pm, soluble ntsev S 30mg/m2 (sib npaug rau NaC1) (3) txheeb ze humidity<60%, stainless steel surface temperature at least 5℃ above the dew point temperature
2. Tsis muaj casting steel xuas nrig ntaus abrasive yuav tsum
(1) Abrasive huv si, tawv, angular (2) PH xeem ntawv PH, qhuav thiab conductivity<1505s/cm (IS011127-6) (3) abrasive quality should be approved by the shipowner and paint manufacturer
Kev taw qhia thiab kev sib piv ntawm kev ntsuas ntsuas ntawm garnet thiab xim av corundum abrasive
1. Garnet thiab xim av corundum abrasive qhia
(1) garnet abrasive
Garnet yog lub ntuj ore ua los ntawm cov abrasive, rau hlau thiab txhuas garnet (tsuas yog hlau-muaj txhuas silicate crystals), hardness feem ntau tsis tshaj 8 Mohs, manufacturers feem ntau muaj loj garnet mines, lub ntsiab tsim nyob rau hauv Shandong, Jiangsu, puab. Mongolia.
(2) Xim av corundum abrasive
Brown corundum yog ua los ntawm bauxite thiab auxiliary cov ntaub ntawv smelted ntawm qhov kub siab tshaj 2, 000 degree nyob rau hauv ib tug hluav taws xob arc rauv. Lub hardness ntawm qib feem ntau yog ntau dua 9 Mohs, thiab cov ntsiab lus alumina yog ntau tshaj 96%. Cov chaw tsim khoom tseem ceeb hauv Henan, Guizhou thiab lwm thaj chaw.
Xuab zeb ntxuav kev sim ntawm garnet thiab xim av corundum abrasives
Cov cuab yeej siv thiab cov kev sim: Kev tiv thaiv ib puag ncig tsis siv neeg xuab zeb ntxhua khaub ncaws, 12 hli theem nrab cua inlet nozzle, roughness tester, 600mm * 800mm stainless hlau phaj 6 daim, garnet thiab xim av corundum abrasive 500kg txhua; Garnet abrasives feem ntau siv nyob rau hauv tsev shipyards thiab xim av corundum abrasives ntawm txawv specifications tau siv rau kev sim sib piv, raws li qhia nyob rau hauv Table 2 thiab Table 3 feem.
Cov txiaj ntsig kev sim hauv Table 3 qhia tias:
(1) Raws li qhov loj me me ntawm cov xim av corundum abrasive txo qis, qhov roughness ntawm stainless hlau kuj txo, tab sis qhov huv si ntawm stainless hlau maj mam nce.
(2) Kev xaiv ntawm thawj chav kawm xim av corundum thiab zoo hlau thiab txhuas garnet abrasive ntsuas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov kev qhia tshwj xeeb.
(3) Piv nrog rau xim av corundum, garnet muaj ib tug congenital tsis muaj hardness, yog li nws tsis zoo li xim av corundum abrasive nyob rau hauv cov nqe lus ntawm xuab zeb xuas nrig ntaus efficiency thiab kev puas tsuaj tus nqi.
(4) Muaj ib qho teeb meem ntawm sanding nyob rau hauv garnet punching xuab zeb, txawm hais tias kev xaiv ntawm me me-particle abrasive tuaj yeem daws cov xuab zeb, qhov roughness tawm yog qhov nyuaj kom ua tau raws li qhov yuav tsum tau ua ntawm 40-75um, thiab {{3} }}mesh grain loj ntawm xim av corundum abrasive tuaj yeem ua tau raws li qhov yuav tsum tau ua.
(5) Qhov saum npoo ntawm garnet tom qab ntxuav xuab zeb yog ci dua thiab zoo nkauj, thiab nws yog qhov zoo dua rau kev huv.
(6) Cov plua plav uas tsim los ntawm ob qho tib si xuab zeb ntxuav yog loj heev, nyob rau hauv kev sib piv, garnet plua plav yog ntau yam teeb meem rau kev ua hauj lwm noj qab haus huv.
xaus
Xav txog cov yam ntxwv xws li kev tswj hwm tus nqi, kev xav tau thiab kev ua haujlwm ntawm kev xuas nrig ntaus, xim av corundum abrasive yog qhov tsim nyog rau daim ntawv thov ntawm stainless hlau nto kho nyob rau hauv lub ballast tank ntawm tshuaj tanker.
