Puas Alloy Hlau Hloov Ntsuab?
Jan 07, 2024| Taw qhia
Cov lus nug ntawm seb cov hlau alloys tig ntsuab yog ib qho, thiab nkag siab zoo li ntawd. Tom qab tag nrho, peb tau pom tag nrho cov pej thuam, cov hniav nyiaj hniav kub, thiab lwm yam khoom siv hlau uas tau coj cov xim ntsuab dhau sijhawm. Tab sis dab tsi ua rau qhov tshwm sim no, thiab nws puas muaj tseeb ntawm tag nrho cov hlau alloy? Hauv tsab xov xwm no, peb yuav tshawb txog cov lus nug no thiab ntau ntxiv.
Alloy yog dab tsi?
Ua ntej dhia mus rau hauv cov lus nug ntawm seb cov hlau alloys tig ntsuab, nws yog ib qho tseem ceeb uas yuav tsum xub to taub tias cov hlau yog dab tsi. Hauv cov ntsiab lus yooj yim, ib qho alloy yog sib xyaw ntawm ob lossis ntau dua hlau. Qhov no tuaj yeem ua tau los txhim kho cov hlau ruaj khov, lub zog, lossis lwm yam ntxwv.
Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm kev sib xyaw tooj liab thiab zinc. Hlau yog lwm yam hlau alloy, muaj hlau thiab carbon. Muaj ntau ntau hom alloys zoo li, qee qhov yog siv rau hauv cov hniav nyiaj hniav kub ua, kev tsim kho, thiab lwm yam lag luam.
Vim li cas Hlau Hloov Ntsuab?
Tam sim no, cia peb mus rau lub plawv ntawm qhov teeb meem: yog vim li cas hlau tig ntsuab? Cov lus teb yog nyob rau hauv tus txheej txheem hu ua oxidation. Thaum cov hlau raug oxygen rau lub sijhawm ntev, nws qhov chaw tuaj yeem hnov mob thiab tsim ib txheej ntawm oxide. Cov oxide txheej no yog dab tsi ua rau cov hlau hloov xim.
Nyob rau hauv cov ntaub ntawv ntawm tooj liab, piv txwv li, no oxide txheej yog ntsuab-xiav nyob rau hauv cov xim thiab hu ua patina. Patina yog cov txheej txheem ntuj tsim uas tshwm sim thaum tooj liab raug rau huab cua thiab noo noo. Sij hawm dhau mus, patina txheej tuaj yeem ua kom tuab thiab ua kom pom tseeb, muab cov hlau sib txawv xim ntsuab.
Puas yog Alloy Hlau Hloov Ntsuab?
Yog li, rov qab mus rau peb lo lus nug qub: puas tag nrho cov hlau alloys tig ntsuab? Lo lus teb tsis yog. Txawm hais tias qee cov alloys tuaj yeem tsim cov patina dhau sijhawm, lwm tus yuav tsis ua. Nws nyob ntawm cov hlau tshwj xeeb uas tsim cov alloy thiab cov xwm txheej uas cov hlau raug.
Piv txwv li, tooj dag tuaj yeem tsim lub patina dhau sijhawm, tab sis cov xim tuaj yeem sib txawv nyob ntawm seb muaj pes tsawg leeg ntawm cov hlau thiab ib puag ncig uas nws tau muab tso rau. Stainless hlau, ntawm qhov tod tes, tsis tshua muaj peev xwm tsim patina vim nws qhov siab tiv thaiv corrosion.
Tiv thaiv Green Patina hauv Hlau
Yog tias koj muaj cov khoom siv hlau uas koj xav tiv thaiv kom tsis txhob tig ntsuab, muaj ob peb yam uas koj tuaj yeem ua tau. Ua ntej, koj tuaj yeem siv cov txheej txheem tiv thaiv rau cov hlau los pab tiv thaiv oxidation. Qhov no tuaj yeem ua tiav siv cov tshuaj pleev xim ntshiab lossis cov khoom tshwj xeeb hlau txheej.
Lwm qhov kev xaiv yog txwv cov hlau raug rau huab cua thiab ya raws. Qhov no tuaj yeem ua tau los ntawm kev khaws cov hlau hauv qhov chaw qhuav lossis los ntawm kev sib khi rau hauv lub thawv tiv thaiv. Txawm li cas los xij, nco ntsoov tias kev tshem tawm tag nrho raug rau huab cua thiab noo noo yuav tsis tuaj yeem ua tau lossis siv tau.
Xaus
Hauv kev xaus, cov lus nug ntawm seb cov hlau alloys tig ntsuab yog nyob ntawm ntau yam, nrog rau cov hlau tshwj xeeb uas tsim cov hlau thiab cov xwm txheej uas cov hlau raug. Oxidation yog cov txheej txheem uas ua rau cov hlau tig ntsuab, thiab thaum patina yog ib qho tshwm sim nyob rau hauv tooj liab thiab lwm yam hlau, tsis yog tag nrho cov alloys yuav tsim hom discoloration. Yog tias koj xav tiv thaiv koj cov khoom hlau los ntawm kev tig ntsuab, muaj cov kauj ruam uas koj tuaj yeem ua, xws li siv cov txheej tiv thaiv los yog txwv tsis pub muaj huab cua thiab noo noo.
