Tshem tawm xeb los ntawm Flange Surfaces - Ib Daim Ntawv Qhia Kom Paub
Taw qhia:
Hlau flanges yog qhov yooj yim rau xeb vim qhov reactive ntawm hlau, uas nkag tau yooj yim nrog oxygen thiab dej hauv huab cua. Xeb tuaj yeem tsim teeb meem hauv cov kav dej, uas tuaj yeem ua rau xau yog tias cov hlau flanges tsis raug tswj xyuas kom zoo. Rust feem ntau adheres rau saum npoo, ua rau nws tshem tawm cov txheej txheem ceev faj kom tsis txhob muaj kev puas tsuaj. Hauv phau ntawv qhia no, peb yuav tshawb nrhiav txoj hauv kev zoo rau tshem tawm xeb los ntawm flange nto.
1. Hlau Hlau Txhuam Ntxuav:
Ib txoj hauv kev zoo rau kev tshem tawm xeb los ntawm qhov chaw flange yog siv cov roj carbon steel hlau txhuam. Cov txhuam hniav no tuaj yeem txhuam tawm qhov xeb ntawm qhov chaw. Tom qab ntawd, kev kho abrasive xws li sandblasting tuaj yeem ua haujlwm. Kev siv cov abrasives xws li xuab zeb, iav hlaws, thiab cov khoom sib tsoo yog tsim rau tshem tawm xeb los ntawm cov hlau, cov hlau tsis tshua muaj hlau, lossis cov hlau cam khwb cia. Cov abrasives feem ntau tsis ua rau kev puas tsuaj rau lub flange nws tus kheej.
2. Acid Bath:
Flanges tseem tuaj yeem tsau rau hauv lub da dej acid kom tshem tawm xeb. Piv txwv li, hydrochloric acid reacts nrog hlau xeb kom yaj nws. Txoj kev no muaj txiaj ntsig zoo hauv kev tshem tawm xeb; Txawm li cas los xij, nws yuav tsum tau ceev faj vim yog qhov corrosive ntawm hydrochloric acid. Dilution lossis siv cov kua qaub tsawg dua tuaj yeem txiav txim siab rau kev nyab xeeb.
3. Kev soj ntsuam zoo:
Txhawm rau tiv thaiv lossis ntes cov hlau seem dawb ntawm qhov chaw flange, kev tshuaj xyuas zoo yog qhov tseem ceeb. ASTM cov qauv, xws li A380, qhia txog kev kuaj corrosion rau cov hlau lossis hlau ntawm cov hlau tsis huv. Yog tias pom cov hlau seem, cov txheej txheem tshuaj tuaj yeem ua haujlwm rau kev tshem tawm xeb. Flanges raug dej rau 12-24 teev tuaj yeem kuaj xyuas qhov xeb hauv qhov kev sim yooj yim. Txoj kev no muaj kev pheej hmoo tsawg thiab siv sijhawm tsawg. Nws yog ib qho tsim nyog sau cia tias hauv kev tsim cov raj xa dej, stainless hlau flanges tuaj yeem siv los hloov cov pa hlau flanges kom txo tau qhov tshwm sim ntawm xeb thiab txo cov nqi kho tom ntej.
Xaus:
Kev tshem tawm xeb los ntawm qhov chaw flange yog ib qho tseem ceeb ntawm kev saib xyuas hauv cov kav dej. Ntau txoj hauv kev tuaj yeem siv tau, suav nrog kev txhuam steel hlau, kev kho abrasive, da dej kua qaub, thiab kev tshuaj xyuas zoo. Kev xaiv ntawm txoj kev nyob ntawm seb hom flange thiab nws cov khoom. Kev saib xyuas tsis tu ncua thiab kev tiv thaiv kev tiv thaiv tuaj yeem pab ntev lub neej thiab kev ntseeg siab ntawm flange kev sib txuas.
SINO SPECIAL METAL yog ib qho kev ntseeg siab ntawm cov kav dej, flanges, thiab fittings. Peb muab cov khoom lag luam zoo kom tau raws li koj qhov project qhov kev xav tau tshwj xeeb. Thov koj xav tiv tauj peb rau kev nug thiab kev yuav khoom.
