Anti-Corrosion Technology rau Screws

Stainless hlau screws yog ua los ntawm cov hlau, thiab muaj plaub yam tseem ceeb ntawm kev tiv thaiv kev xeb hlau: cov khoom siv los ntawm cov khoom siv, kev khiav hauj lwm ib puag ncig, kev sib tshuam ntawm cov khoom thiab ib puag ncig, thiab kev txhim kho rau cov hlau cov qauv tsim. Kev tsim stainless hlau screws los ntawm tag nrho corrosion-cov alloys resistant feem ntau tsis raug nqi-tshwj tsis yog tias muaj cov cai tshwj xeeb, thiab tag nrho cov ntsia hlau qhov saum npoo los ntawm corrosive ib puag ncig yam tsis zoo. Thaum txhim kho cov qauv tsim tuaj yeem txo qhov cuam tshuam ntawm cov xwm txheej tshwj xeeb, cov qauv tsim ntawm cov hlau tsis muaj steel feem ntau tsis tuaj yeem hloov pauv tau, thiab cov kev tiv thaiv zoo li no tsis ruaj khov; Yog li, qhov kev qhia no tsis tsim nyog daws qhov teeb meem. Yog li ntawd, nto - qib tiv thaiv corrosion - tshwj xeeb, nto tiv thaiv - kev kho corrosion - yog txoj kev siv dav tshaj plaws.

Deg los tiv thaiv- kev kho corrosion rau stainless hlau screws koom nrog siv txheej tiv thaiv rau hlau nto siv ntau txoj kev. Lub luag haujlwm ntawm cov txheej txheem no yog cais cov hlau los ntawm qhov chaw corrosive, yog li inhibiting txheej txheem corrosion los yog txo kev sib cuag ntawm corrosive media thiab hlau nto los tiv thaiv lossis txo corrosion.

Cov txheej tiv thaiv yuav tsum ua tau raws li cov cai hauv qab no:
1. Corrosion kuj, hnav tsis kam, thiab siab hardness.
2. Cov qauv ntom ntom ntom ntom ntom ntom nrog cov porosity tsawg.
3. Muaj zog sib txuas thiab adhesion rau lub hauv paus hlau.
4. Uniform faib thiab txaus thickness.

Cov khaubncaws sab nraud povtseg feem ntau tau muab faib ua cov xim hlau thiab tsis yog -cov xim hlau. Cov hlau coatings koom nrog kev tsim cov txheej txheem tiv thaiv corrosion- siv cov hlau tsis zoo siv cov hlau tsis zoo- tiv taus hlau lossis hlau; cov no feem ntau hu ua "platings." Muaj ntau txoj hauv kev thiab hom hlau txheej; Feem ntau yog electroplating, ua raws li cov hlau molten dipping (kub-dip txheej) thiab tshuaj kho qhov chaw. Tsis yog-cov xim hlau yog siv cov ntaub ntawv organic polymer (xws li xim) lossis cov ntaub ntawv inorganic (xws li ceramics) rau saum npoo ntawm cov khoom siv hlau lossis cov khoom siv. Cov txheej txheem no cais cov hlau hauv ib puag ncig, tiv thaiv corrosion los ntawm kev sib cuag nrog cov neeg ua haujlwm corrosive.
