Cov Lus Qhia Luv luv ntawm Cov Khoom Siv Liab
Cov ntaub ntawv ntawm tooj liab
| Nta | Cov ntaub ntawv |
| Subtypes | 101, 110 |
| Kev ua | CNC Machining, sheet hlau fabrication |
| Kev nyiaj tau | ISO 2768 |
| Cov Ntawv Thov | Cov chaw tsheb npav, Gaskets, cov txuas hlau hlau, thiab lwm yam kev siv hluav taws xob |
| Cov kev xaiv ua tiav | Muaj xws li-machined, tshaj tawm tawg, lossis txhais tes polished |
Muaj tooj liab subtypes
| Zeeg | Lub zog tensile | Elongation thaum so | Kev nyuaj | Ceev | Qhov siab tshaj plaws temp |
| 110 tooj liab | 42,000 psi (1/2 nyuaj) | 20% | Rockwell F40 | 0.322 lbs / CU. nyob rau hauv. | 500 ° F |
| 101 Tooj | 37,000 psi (1/2 nyuaj) | 14% | Rockwell F60 | 0.323 lbs / cu. nyob rau hauv. | 500 ° F |
Cov Lus Qhia Dav Dav Hlau Rau Tooj Liab
Txhua tus tooj liab Alloys tiv thaiv corrosion thiab chav dej. Hauv feem ntau nyob deb nroog, marine thiab cov chaw lag luam tooj cua tshuab hluav taws xob kuj tseem tiv taus corrosion. Tooj liab tiv thaiv kua qaub, xau, tsis-oxidising minerals, organic acids thiab caustic daws teeb meem. Murg noo ammonia, halogens, sollphides, cov kev daws teeb meem muaj ammonia ions thiab oxidising acids, xws li nitric acid, yuav tawm tsam tooj liab. Cov aloys tooj liab tseem muaj tsis zoo rau cov inorganic acids.
Lub corrosion tsis kam ntawm cov taum tooj liab alloys los ntawm kev tsim cov duab kos ntawm cov khoom sib dhos ntawm cov khoom saum npoo. Cov yeeb yaj kiab no kuj tsis zoo rau kev xeb yog li kev tiv thaiv cov hlau los ntawm kev tawm tsam ntxiv.
Tooj liab nickel alloys, txhuas tooj liab, thiab txhuas bronzes ua rau pom kev zoo tshaj rau Saltet dej corrosion.
Hluav Taws Xob Kev Tshaj Tawm
Hluav taws xob hluav taws xob ntawm tooj liab yog zaum ob nkaus xwb rau nyiaj. Qhov kev tshaj tawm ntawm tooj liab yog 97% ntawm kev ua haujlwm ntawm cov nyiaj. Vim nws cov nqi qis dua thiab ntau dua ntau nplua nuj, tooj liab tau ib txwm yog cov qauv siv rau cov ntaub ntawv sib kis.
Txawm li cas los xij, kev txiav txim siab hnyav txhais tau tias kev faib ua feem loj ntawm cov nyiaj ntau dua hluav taws xob cov kab hluav taws xob hnyav tam sim no ntau dua tooj liab. Los ntawm qhov hnyav, qhov kev coj ua ntawm txhuas yog nyob ib ncig ntawm tooj liab. Cov alloys aluminium siv tau muaj lub zog tsawg thiab yuav tsum tau txhawb nrog lub galvanized los yog txhuas coated high tensile steel hlau hauv txhua strand.
Txawm hais tias ntxiv rau lwm cov ntsiab yuav txhim kho cov khoom zoo li lub zog, yuav muaj qee qhov poob hauv hluav taws xob conductivity. Ua piv txwv A 1% ntxiv rau Cadmium tuaj yeem ua rau muaj zog los ntawm 50%. Txawm li cas los xij, qhov no yuav ua rau muaj kev txo qis hauv hluav taws xob kev ua haujlwm ntawm 15%.
