Thaum tej yam xeb, nws yog lub sij hawm los hloov lawv los yog kom lawv rov zoo li qub. Txawm li cas los xij, nrog patina nws txawv, ntawm no hlau yog txhob txwm ua rau xeb kom txhob txwm ua kom zoo nkauj zoo nkauj.
Patina yog dab tsi?
Thaum xeb yog qhov tsis zoo ntawm huab cua thiab lub sijhawm ntawm cov hlau, patina tshwj xeeb txhawb cov khoom ua haujlwm kom xeb. Ntau yam ntawm cov qauv thiab cov duab kos ntawm patina yog tsim los ntawm ntau cov tswv yim thiab cov txheej txheem
Kev kho kom zoo nkauj hauv hlau saib
Thaum tsim chav nrog ntoo, nws yog qhov nrov los muab cov ntoo qub thiab cov khoom tshiab, cov rooj tog zaum. Ua li no koj ua ib nqe lus rau cov khoom 'ntoo'. Cov khoom sib xyaw no kuj tseem tuaj yeem hloov mus rau hlau: cov hlau qub, txawm tias muaj lossis tsis muaj xeb, tuaj yeem ua ke nrog cov txee niaj hnub thiab cov phab ntsa, piv txwv li kom ua neej nyob hauv kev lag luam hauv tsev hauv txoj kev zoo nkauj. Ib feem ntawm qhov sib xyaw no tuaj yeem yog cov hlau phaj uas tuaj yeem luam tawm nrog cov duab. Koj tsis tas yuav ua yam tsis muaj hlau rau phab ntsa yees duab thiab koj tuaj yeem tsim kho kom zoo nkauj phab ntsa.
Cov khoom zoo
Thaum ua koj tus kheej patina, koj xav cia ib tug nto xeb "ceev" thiab tsis txhob tos rau cov xwm los ua nws txoj kev. Yuav kom qhov no ua haujlwm, ob peb yam yuav tsum tau coj mus rau hauv tus account.
Xiav tsuas yog ua haujlwm nrog cov hlau uas muaj hlau; lwm yam hlau kuj hnov mob nrog huab cua dhau sijhawm, tab sis tsis txhob tsim cov xim kub-xim av patina. Piv txwv li, tooj liab yuav nws thiaj li tsim verdigris thiab txhuas yuav tsim dawb-grey txhuas xeb.
Cov txheej txheem zinc
Vim tias galvanizing yog txheej txheej tiv thaiv zoo heev tiv thaiv xeb, nws raug nquahu kom npaj cov khoom siv hlau ncaj qha.
Ungalvanized du steel ntawv yog tshwj xeeb tsim,
- vim nws ruaj khov heev
- tsis yog tus nqi siab heev
- vim nws xeb sai thiab zoo
Tip:
Siv cov hlau nplaum los kuaj seb cov khoom xav tau puas muaj hlau / yog hlau nplaum.
Tshem tawm galvanizing
Acetic acid tuaj yeem tua zinc thiab txawm tshem tawm cov galvanizing. Qhov no yog qhov tsim nyog yog tias koj xav muab lub tin tuaj yeem ua kom pom rusty.
Nrog cov cuab yeej tiv thaiv tsim nyog, koj tuaj yeem tshem tawm cov kev tiv thaiv galvanizing nrog cov ntxhua khaub ncaws da dej (nrog hydrochloride).
Tip:
Yog tias ua tau, koj yuav tsum tso cov hlau tseem galvanized rau hauv cov kua qaub ib hmos thiab tom qab ntawd tshem tawm cov khoom seem ntawm cov galvanization rau hnub tom qab uas siv hnab looj tes thiab cov abrasives (xaim txhuam, ntawv xuab zeb tsis muaj dej).
Cov lus qhia rau patina
Txij li thaum tsim cov patina ib txwm muaj cov av me ntsis, koj yuav tsum tiv thaiv qhov chaw thiab tsis txhob ua yam tsis muaj lub hauv paus, vim tias xeb stains nyuaj rau tshem tawm.
Txoj kev yooj yim
