Kev ntseeg tau ntawm Astm B117 Txujcab Ntsev Tshuaj Tsuag

1. Kev soj ntsuam ntawm tus txheej txheem tseem ceeb ntawm Astm B117 Ntsev Tshuaj Tsuag
Kev Ntsuas Cov Mob
Yaus tsis: 5% sodium vloride tov (huv ntau dua lossis sib npaug ntawm 99%), pH tus nqi nruj me ntsis tswj ntawm 6. {}. 2; Kev ntsuas qhov kub thiab txias: Qhov ntsuas kub ntawm qhov ntsuas ntsuas yog tas li ntawm 35 ± 1 degree, ib puag ncig siab ntawm chaw kub / substropical ntug hiav txwv; Tshuaj txau: Kev sib xyaw ua ke ntau dua los yog sib npaug 24 teev (cov ntaub ntawv pov thawj niaj hnub yuav tsum tau txuas ntxiv rau {8}} teev. Qauv Qauv Pretreatment Specifications
Tu kom tu: Siv cov tshuaj acetone thiab deionized los ntxuav hauv kev tig mus rau tshem tawm cov roj thiab oxide txheej kom tsis txhob cuam tshuam rau kev txiav txim siab corrosion; Txiav cov txheej txheem: Khaws thawj lub xeev, thiab ntug yuav tsum tau polished los tiv thaiv kev phais mob ntawm kev cuam tshuam nrog cov ntaub ntawv raug. Ii. Cov cim tseem ceeb rau kev lees paub kev lees paub ntawm txhuas siv hauv cov ntug hiav txwv
Corrosion Qib Kev Ntsuam Xyuas
Cov tsos tshuaj xyuas: sau thaj tsam ntawm cov pob dawb (pitting) thiab sib faib cov qib corrosion), thiab faib cov qib (0 qib kawm);
Lub cev yuag txheej txheem: ntsuas qhov loj sib txawv ntawm cov hnoos qeev ua ntej thiab tom qab ntsuas tus nqi corrosion, suav tus nqi uas tau tso cai tsawg dua los yog sib npaug}. 1 (6061 Aluminium).
Kev Tiv Thaiv Txheej Txheem Kev Ntsuam Xyuas
Anodic oxide zaj duab xis: Thaum cov yeeb yaj kiab thickness loj dua los yog sib npaug (tooj liab ceev) yuav tsum muaj 48 teev yam tsis muaj substrate corrosion;
Txheej adhesion: Tom qab daim kab xev peeting xeem (Astm D3359), txheej txheej txheej txheej av yog<5% to be qualified.
III. Kev Ntsuam Xyuas Daim Ntawv Tshaj Tawm Kev Tshawb Fawb thiab Kev Sau Npe
Cov ntaub ntawv sib piv thiab tsom xam
Horizontal comparison‌: compare the sample data with the historical data of the same batch/supplier, and the deviation >20% yuav tsum tau pib ntawm kev ua kom zoo traceability;
Kev txheeb xyuas qhov tseeb: Dynamically Kho lub sijhawm ntsuas ua ke nrog cov kev pabcuam ib puag ncig hauv salinity hauv qingdao thiab sanya). Kev txiav txim cov khoom xaiv
Nyiam cov siab corrosion-resistant alloys: 5083 txhuas-magnesium alloy yog pom zoo ({} teev} teev ntsev txau<0.05g/m²·h);
Kev Kho Txoj Kev Kho Mob: 6063 cov profer nrog micro-arc oxidation cov txheej txheem tuaj yeem txhim kho ntsev txau txau ntau dua 3 zaug.
IV. Kev Txhim Kho Cov Phiaj Xwm rau Nqaum Nqaum Tej Ntxhuav
Anti-corrosion tsim kev txhim kho
Txheej Txheem Txheej Txheem: Ntau-Cavity Profile Tsim + Dej Qhov Dej Kom Txo Ntsev Txom Sij Hawm Rov Ua Haujlwm;
Txhim kho cov sealing: Silicone cov qauv nplaum thiab cov fluorocarbon txheej thiab cov fluorocarbon siv ua ke los thaiv txoj hauv kev nkag mus.
Cov ntsiab lus tseem ceeb ntawm cov khoom siv tshuaj tiv thaiv kev pheej hmoo
Cov ntaub ntawv pov thawj: Cov neeg muab khoom siv ASTM B117 daim ntawv tshaj tawm (suav nrog cov ntaub ntawv qub thiab ib puag ncig cov ntaub ntawv hauv ib puag ncig);
Thib peb kev soj ntsuam rov tshuaj xyuas: Rau cov ntsaws cov khoom tseem ceeb: CNA Cov chaw lis haujlwm muaj ntawv pov thawj lub chaw soj ntsuam lub chaw soj ntsuam.
