Cov tshuaj tshwj xeeb yog siv los tiv thaiv qee yam ntawm lub tsev tsim los ntawm corrosion. Ua tsaug rau lawv cov khoom, cov khoom siv kho kom zoo nkauj thiab kev huv thiab huv ntawm cov qauv raug txhim kho. Ib qho ntawm cov khoom sib xyaw no yog hlau tsawg. Cov tshuaj no kuj tseem siv tau rau ntau qhov xwm txheej.
Yuav ua li cas hlau mini yog ua los ntawm
Powder, uas yog tau los ntawm kev sib tsoo hlau ore hlawv mus rau lub xeev ntawm nplai, tiv taus kub, huab cua thiab teeb pom kev zoo. Cov xim liab-xim av yog tsim los ntawm hlau oxide.
Calcining limonite ore huab hwm coj nyob rau hauv ib puag ncig oxygen-air, nws yog coj mus rau qhov xav tau sib xws. Tom qab ntawd, crushed nyob rau hauv lub plab ntawm ib tug tshwj xeeb tshuab hu ua "roar", cov hmoov yog ntim rau hauv ib lub hnab los yog hlau thawv rau cov khoom xa tuaj rau cov lag luam. Kev koom tes hauv kev tsim cov saw hlau ua cov khoom tseem ceeb lossis ntxiv, cov hlau lead liab muaj ntau yam kev siv.
Indispensable raw khoom
Produced fromore pigment tau ntse siv nyob rau hauv ntau yam lag luam:
- hauv kev lag luam xim thiab kua roj vanish hauv kev tsim cov primers thiab xim sib tov;
- hauv glassworks;
- hauv kev lag luam tsheb;
- in plastics related;
- hauv kev tsim cov nplaim hluav taws kub hnyiab thiab cov tebchaw;
- thaum polishing iav thiab hlau qhov chaw ua cov khoom zoo abrasive.
Ntxiv rau, qee qhov ntawm cov tsheb tshiab tau coated nrog cov khoom no, vim qhov kev ua no zoo kawg nkaus tiv thaiv cov hlau los ntawm xeb.
Tsuas paub siv xim
Qhov ruaj khov tshaj plaws ntawm cov kua tshuaj tiv thaiv corrosion yog hlau tsawg. Specifications tso cai rau siv cov xim no rau kev kho mob ntawm lub tsheb hauv qab thiab cov kav dej. Hlau ru tsev thiab manhole npog, cua sov radiators thiab hlau garages raug kho nrog tus neeg sawv cev no. Tsis tas li ntawd, hlau miniium yog siv los npog cov ntoo ntawm lub tsev, tsis hais qhov chaw sab hauv lossis sab nraud. Cov tshuaj no tsis pom zoo rau kev pleev xim rau hauv pem teb.
Xim yog tsim los ntawm cov hmoov hlau yaj hauv penftal (roj) varnishes. Txhawm rau tswj lub xeev ntawm kev ncua, thixotropic thiab desiccant additives yog ntxiv rau qhov sib tov. Tom qab obligatory sib tov thiab ntim, cov huab cua-resistant anti-corrosion xim miniium hlau (xim xim av) yog npaj txhij rau siv.
Cov xim pleev xim lossis xim ntuj: uas zoo dua
Cov xim qhuav, lossis cov xim, hu ua hmoov zoo ntawm cov xim sib txawv insoluble hauv tshuaj hnyav. Cov hmoov inorganic uas yog ib feem ntawm cov xim tsev muab rau npog qhov no lossis qhov ntxoov ntxoo. Tsis tas li ntawd, qhov sib ntxiv ntawm cov hmoov pigment, xws li hlau mini, txhim kho tsis tau tsuas yog cov tshuaj tiv thaiv corrosion, tab sis kuj muaj kev tiv thaiv txhua yam ntawm cov muaj pes tsawg leeg.
Hauv kev lag luam, ob hom dyes yog siv: khoom tsim thiab ntuj. Synthetic fillers yog qhov txawv ntawm lawv qhov ci, ntau yam thiab saturation ntawm cov xim palette. Ntuj dyes yog mined los ntawm lub plab hnyuv ntawm lub ntiaj teb. Lawv yog cov pheej yig, tsis muaj teeb meem thiab zoo dua resistant rau sab nrauv influences. Cov hlau me me belongs rau pawg thib ob. Cov tshuaj hauv qab no kuj tseem muaj cov ntxhia pob zeb ntuj:
- dawb chalk thiab daj ocher;
- xim av thiab daj daj sienna;
- liab cinnabar thiab dub-grey pyrolusite;
- graphite thiab bauxite.
Yuav siv xim li cas
Ua ntej yuav pleev xim, ua tib zoo npaj qhov chaw. Tshem tawm xeb thiab roj, plua plav thiab nplai. Cov xim yuav tsum sib tov zoo. Yog tias tsim nyog, muaj pes tsawg leeg yog diluted nrog hnyav, turpentine lossis dawb ntsuj plig los tsim kom muaj qhov xav tau ntawm qhov ntom ntom.
Iron miniium yog siv rau qhov chaw npaj nrog txhuam zoo tib yam. Lub sij hawm ziab ntawm cov txheej yog nyob ntawm qhov kub thiab txias thiab tuaj yeem nyob ntawm 20 mus rau 24 teev. Rau kev tiv thaiv zoo dualos ntawm kev cuam tshuam sab nraud, cov xim muaj pes tsawg leeg yog siv rau hauv ob peb txheej, tom qab tos kom tiav ziab ntawm yav dhau los. Yog tias koj maj nrawm thiab tsis quav ntsej txoj cai ntawm cov thev naus laus zis no, txheej txheej yuav tsis ua raws li qhov tsim nyog. Cov xim xim zaj duab xis yuav wrinkled thiab yooj yim puas.
ntsuas kev nyab xeeb ntawm kev ua haujlwm
Thaum pleev xim rau koj tus kheej, koj yuav tsum ua raws li cov cai yooj yim. Cov hauv no suav nrog cov khoom hauv qab no:
- Chav tsev uas siv cov hlau me me yuav tsum tau tso cua rau ob lub sijhawm thiab tom qab lub sijhawm pleev xim.
- Kev haus luam yeeb thiab siv cov nplaim taws qhib ze ntawm qhov chaw ua haujlwm raug txwv.
- Tes yuav tsum hnav roj hmab lossis hnab looj tes pov tseg. Koj tuaj yeem siv cov tshuaj tiv thaiv tshwj xeeb bio-cream.
- iav yuav tiv thaiv koj ob lub qhov muag los ntawm kev sib tsoo ntawm microdrops ntawm cov xim ntawm lub cornea.
Yog hais tias muaj pes tsawg leeg tau txais ntawm daim tawv nqaij uas tsis muaj kev tiv thaiv los ntawm cov khaub ncaws, nws yuav tsum tau muab tshem tawm nrog cov ntaub so ntswg ntub dej los yog cov roj zaub. Tom qab ntawd yaug nrog dej sov thiab tsev neeg degreaser lossis xab npum.
Tom qab ua tiav txoj haujlwm, cov hlau me me uas tseem tshuav yog khaws cia kom deb ntawm cov khoom siv cua sov thiab qhov hluav taws kub. Lub hub yuav tsum kaw nruj nreem kom tsis txhob thickening thiab ziab ntawm cov muaj pes tsawg leeg. Tsis txhob khaws cov xim nyob rau hauv lub hnub, te los yog los nag.
