Cov khoom siv rau kev tshem tawm hauv zos ntawm xeb thiab galvanizing ntawm lub cev tsheb
Txheem
Cov khoom siv tsis yog tsuas yog tshem tawm corrosion, tab sis kuj galvanizing ntawm thaj chaw teeb meem. Cov txheej txheem muaj nyob rau hauv galvanizing lub cev, uas muab kev tiv thaiv xeb corrosion, piv rau cov ua nyob rau hauv lub Hoobkas. Cov khoom siv muab kev tshem tawm hauv zos ntawm qhov tsis xws luag yam tsis tas yuav ntxuav lub ntsej muag ntawm tag nrho lub cev.
Feem ntau cov tswv ntawm cov tsheb laus dua 5 xyoos ntsib teeb meem ntawm xeb tsim, tshwj xeeb tshaj yog rau kev lag luam tsheb hauv Lavxias. Koj tuaj yeem tiv thaiv koj tus kheej nrog kev pab ntawm cov khoom siv rau kev tshem tawm xeb hauv zos thiab tom qab galvanizing ntawm qhov chaw ntawm lub tsheb lub cev.
Cov khoom siv tshem tawm xeb
Yuav kom tsis txhob nrhiav chemistry ntawm koj tus kheej, koj tuaj yeem yuav cov khoom siv uas muaj txhua yam koj xav tau.
"Korocin"
Cov khoom siv tsis yog tsuas yog tshem tawm corrosion, tab sis kuj galvanizing ntawm thaj chaw teeb meem. Cov txheej txheem muaj nyob rau hauv galvanizing lub cev, uas muab kev tiv thaiv xeb corrosion, piv rau cov ua nyob rau hauv lub Hoobkas. Cov khoom siv muab kev tshem tawm hauv zos ntawm qhov tsis xws luag yam tsis tas yuav ntxuav lub ntsej muag ntawm tag nrho lub cev.

Qhov zoo ntawm lub teeb
Kev kho lub cev nrog "Korotsin" muaj qhov zoo dua lwm txoj hauv kev tshem tawm xeb:
- corrosion raug tshem tawm los ntawm qhov tob tob yam tsis muaj kev cuam tshuam, cov hlau tsis raug puas tsuaj;
- galvanic galvanization nkag mus rau hauv cov txheej txheej sab saud ntawm cov hlau, yog tsau rau hauv nws thiab muab cov txheej tiv thaiv ruaj khov uas tiv thaiv kev rov ua dua;
- xaim ntev ntawm 5 meters tso cai rau koj mus galvanize nyuaj-mus txog qhov chaw ntawm ib sab ntawm lub tsheb;
- lub teeb muaj 2 lub khob yas uas yooj yim rau kev siv tshuaj thiab tsis suav nrog cov khoom sib kis;
- cov chaw tsim khoom kuj muab cov khoom siv khoom seem;
- Zinc plating anode qhov ntau thiab tsawg yog tsim rau thaj chaw loj thiab me.
Lus qhia rau kev siv
Cov txheej txheem rau kev ua lub cev:
- Tshem tawm cov xim residues thiab xeb los ntawm qhov chaw.
- Nruab cov txiv ntseej anodized ntawm lub electrode thiab nruj, tom qab ntawd muab tso rau ntawm tus neeg thov kev xav.
- Ua cov cheeb tsam hauv cheeb tsam los ntawm kev kho cov xaim ua ntej ntawm lub davhlau ya nyob twg zoo.
- Hloov cov txiv ntoo anodized rau zinc.
- Txheej txheem lub cev los ntawm kev sib piv nrog cov kauj ruam dhau los.
Tom qab ntxuav, yaug cov cuab yeej siv nrog dej ntws.
Zincor
Cov cuab yeej yog tsim nyob rau hauv Moscow thiab suav hais tias yog ib qho analogue ntawm Korotsin.
Qhov zoo ntawm lub teeb
"Zinkor" muab cov neeg yuav khoom nrog ntau qhov zoo piv rau lwm txoj hauv kev tshem tawm corrosion:
- kev ua haujlwm tsis tas yuav muaj kev txawj tshwj xeeb;
- tsis tas yuav rhuav tshem lub cev ntawm lub tshuab;
- muab ob npaug ntawm kev tiv thaiv (barrier thiab cathodic);
- tom qab vuam ntawm cov ntawv hlau thiab pleev xim yog tso cai;
- Cov chaw tsim khoom thov lub sijhawm tiv thaiv xeb txog li 50 xyoo.
Thaum siv tau zoo, rov ua dua corrosion tsis zoo li.

Lus qhia rau kev siv
Tus txheej txheem:
- Txuas cov xaim mus rau qhov zoo kawg nkaus ntawm lub roj teeb.
- Muab ib daim txhuam cev rau ntawm lub electrode thiab tsau rau hauv cov tshuaj tshuaj No. 1.
- Mechanically tshem tawm xeb kom txog thaum nws ploj tag (ntxuav chrome ntsiab kom zoo thiab tsuas yog los ntawm sab nraud).
- Yog hais tias cov kab ntawm corrosion nyob twj ywm, tshem tawm lawv mechanically nrog sandpaper.
- Tom qab ua tiav, cov khoom siv thiab hlau yuav tsum tau ntxuav nrog dej ntws.
- Reconnect tus electrode rau lub roj teeb.
- Muab daim txhuam cev tso rau hauv ib lub thawv nrog tshuaj No.2.
- Siv zinc nyob rau hauv tas li txav, txhuam rau ob peb feeb. Nyob rau hauv cov txheej txheem ntawm kev ua, koj tsis tuaj yeem nres thiab tso cai rau qhov pom ntawm qhov tsaus nti ntawm qhov chaw.
Tom qab kev ua haujlwm, cov khoom siv thiab lub cev raug ntxuav dua. Priming thiab tom qab painting ntawm galvanized nto yog nqa tawm tom qab ua tiav ziab.
