Txawm hais tias muaj kev hloov pauv tas mus li ntawm kev tsim kho kev lag luam nrog cov qauv tshiab ntawm cov xim thiab cov kua roj vanish, paub rau ntau tiam neeg, nyiaj tseem tseem yog ib tus thawj coj ntawm cov xim rau hlau thiab qee qhov chaw.
Cov xim no tsis muaj ib milligram ntawm cov nyiaj thiab yog hmoov txhuas nrog cov yam ntxwv xim nyiaj. Yog li no lub npe sib tham - "serebryanka". Hauv kev xyaum, nws tsis muaj dab tsi ntau dua li hmoov txhuas. Muaj ob qhov paub feem ntawm cov hmoov txhuas-PAP-1 thiab PAP-2.
Kuj tseem muaj lwm hom hmoov hlau uas muaj xim kub. Nws yog ua los ntawm tooj dag, yog li nws yuav tsum tsis txhob meej pem nrog txhuas hmoov xim. Cov hmoov tooj liab, diluted nrog cov kua roj vanish lossis roj linseed, muab cov khoom pleev xim rau xim kub.
Txoj hauv kev ua aluminium zas
Qhov sib txawv ntawm ob feem nyiaj ntawm cov lus dag hauv qib sib tsoo ntawm txhuas; yog li ntawd, PAP-1 muaj qhov loj me me me me. Txawm li cas los xij, qib ntawm kev zom tsis cuam tshuam rau qhov zoo ntawm cov xim tha xim.
Txoj hauv kev ua kom cov hmoov txhuas qhuav qhuav yog qhov tseem ceeb dua ntawm no. Txhawm rau kom ua tiav cov zas xim los ntawm nws, ntau yam, feem ntau yog alkyd thiab acrylic varnishes, cov kuab tshuaj thiab txha hniav laus tau siv.
Yog tias xav tau, txhawm rau txhawm rau txhawm rau nws, koj tuaj yeem siv cov xim thiab cov kua roj vanish nrog ntxiv cov ions. Cov zas no yog siv thaum tha xim sab hauv.
Ob qho hmoov tuaj yeem sib xyaw nrog ib qho ntawm cov kua roj vanish lossis sib xyaw nrog cov khoom cua ziab kom qhuav. Qhov sib txawv tseem ceeb ntawm PAP-1 thiab PAP-2 hauv lawv qhov kev npaj yog nyob rau hauv kev ua raws li kev faib ua feem ntawm cov hmoov thiab cov kuab tshuaj:
- Txhawm rau dilute PAP-1, siv cov kua roj vanish BT-577 hauv qhov sib piv ntawm 2 txog 5. Cov xim pleev tau npaj ua li no tuaj yeem tiv taus cua sov txog 400 degrees Celsius thiab tsis hlawv tawm. Rau kev sib xyaw, cov kua roj vanish tau nchuav rau hauv ib feem rau hauv cov hmoov txhuas uas tau nchuav rau hauv lub khob.
- Rau kev npaj ntawm PAP-2 feem, kev faib ua feem ntawm 1 txog 3 lossis 1 txog 4 tau siv. Tab sis nws yuav tsum nco ntsoov tias vim yog qhov sib xyaw ua ke, cov xim pleev xim rau, tsim kom muaj tuab tuab txaus uas tsis tsim nyog siv. Yog li ntawd, nws yuav tsum tau dilution ntxiv kom coj nws mus rau lub xeev hu ua xim sib xws. Cov qib ntxiv ntawm cov dej ntws ntawm cov zas yuav tsum tau xaiv nyob ntawm tus txheej txheem uas nws yuav siv - nrog rau cov menyuam, rab phom, txhuam thiab lwm yam.
Txhawm rau pleev xim, siv qhov sib xyaw ntawm ob lossis ntau cov kuab tshuaj xws li dab dawb, turpentine, hnyav los yog ib tug ntawm lawv. Yog tias koj npaj siab yuav txau cov nyiaj, tom qab ntawd cov hmoov hlau thiab cov kuab tshuaj yuav tsum sib xyaw ua ke sib npaug, thaum 2 rau 1 piv yog haum rau cov menyuam thiab txhuam xim.
Yog tias cov xim tau diluted nrog cov roj linseed hluavtaws, tom qab ntawv tsis muaj qhov sib txawv tseem ceeb los ntawm dilution nrog cov kua roj vanish thaum nws npaj. Tib yam siv rau kev ua raws cai ntawm kev sib piv.
Raws li rau lub txee lub neej, rau cov hmoov hlau nws tus kheej, nws yog qhov siv tau yam tsis muaj kev txwv, thaum cov tshuaj sib xyaw ua ke tuaj yeem khaws cia tsis pub ntau tshaj rau lub hlis.
Khoom
Cov yam ntxwv ua haujlwm ntawm kev sib xyaw ntawm cov xim no feem ntau yog nyob ntawm hom kua roj vanish lossis txha hniav laus uas tau siv los npaj lawv. Tab sis muaj qee qhov txiaj ntsig uas muaj tus yam ntxwv zoo ib yam ntawm txhua hom kev sib xyaw xim no:
- Txhua tus ntawm lawv muaj peev xwm tsim cov teeb meem cuam tshuam rau hauv daim ntawv ntawm cov zaj duab xis ruaj ruaj ntawm cov xim pleev xim. Nws dhau los ua kev tiv thaiv kev tiv thaiv tiv thaiv kev nkag mus rau noo noo thiab lwm yam kev cuam tshuam sab nraud.
- Aluminium hmoov zas yog qhov xav tau. Cov cuab yeej no ntawm kev cuam tshuam txog lub hnub ci hluav taws xob ultraviolet pab tiv thaiv cov nplaim ntawm cov tsev thiab cov qauv pleev xim nrog hmoov txhuas los ntawm kev ua kom sov hauv huab cua sov.
- Tsis muaj qhov tseem ceeb tsawg yog kev tiv thaiv zoo ntawm dyes raws li hmoov txhuas. Lawv tsis raug rau corrosion thiab ntseeg tau dag ntawm cov xim pleev xim, ua raws nws.
Cov zas no muaj muag nyob rau hauv daim ntawv ntawm cov hmoov hlau. Txhawm rau kom tau txais cov zas xim, nws yuav tsum tau sib xyaw nrog cov xim pleev kom haum.
Kuj tseem muaj cov xim sib xyaw ua kom tiav. Cov tom kawg tau sib tov ua ntej siv thiab, yog tias tsim nyog, diluted nrog cov kuab tshuaj kom muab cov xim sib xws uas xav tau. Silverfish tau muag hauv cov xim tha xim lossis cov kaus poom, nrog rau hauv cov kaus poom aerosol.
Aerosol ntim tau yooj yim heev hauv kev siv thiab khaws cia . Thaum siv tshuaj tsuag xim, tsis tas yuav muaj cov khoom pleev xim ntxiv. Acrylic lossis lwm yam xim raws cov dej sib xyaw tau muab rau hauv tib daim ntawv aerosol.
Qhov xav tau ntau tshaj yog rau cov xim sib xyaw ua ke rau kev npaj ua-nws-koj tus kheej ua tiav cov khoom sib xyaw thiab cov tshuaj aerosol. Lawv tuaj yeem muaj cov xim sib txawv, siv thaum pleev xim rau me me lossis siv thaum dai phab ntsa.
Qhov zoo thiab qhov tsis zoo
Cov khoom muaj qhov zoo hauv qab no:
- Qhov nrov ntawm cov hniav nyiaj hniav kub, uas tsis tau poob rau ntau caum xyoo, yog vim nws cov yam ntxwv xws li kev yooj yim ntawm kev thov. Feem ntau, cov zas ziab no tsis poob hauv ib txheej txawm tias tau npaj ua ntej lawm. Txawm hais tias thaum qhov chaw ntsug lossis ib sab xws li phab ntsa lossis toj roob hauv pes pleev xim nrog cov nyiaj, cov dej ntws tsis tau tsim.
- Cov nplaim pleev xim nrog cov xim no txawv los ntawm lub zog loj. Cov xim muaj teeb meem ntog rau saum npoo hauv ib txheej txawm tias, tom qab ziab, ua cov zaj duab xis nyias rau ntawm nws. Nws tsis flake tawm thiab sticks ruaj rau nws puag.
- Aluminium hmoov thiab xim aerosol muaj ntau yam heev. Feem ntau, cov xim nyiaj tau siv los tiv thaiv cov khoom hlau los ntawm kev xeb, txawm li cas los xij, nws tuaj yeem siv rau lwm qhov hauv paus xws li ntoo, pob zeb, plaster, thiab lwm yam. Ib qho piv txwv yog kev sib xyaw nrog cov khoom sib xyaw npaj ntawm cov kua roj vanish lossis txha hniav laus nrog acrylic puag. Cov duab zoo li no tiv thaiv cov tsev ntoo los ntawm rotting thiab ziab tawm ntev, ua rau lawv lub neej nyob ntev.
- Hmoov nyiaj dyes yog ib puag ncig zoo, vim txhuas hmoov tsis yog tshuaj lom. Qhov muaj pes tsawg leeg ntawm nws tuaj yeem ua tshuaj lom tsuas yog tias nws cov hmoov tau diluted nrog cov tshuaj lom lom. Yog li ntawd, rau kev kho kom zoo nkauj phab ntsa hauv thaj chaw nyob, sib xyaw raws cov xim tsis muaj tshuaj lom thiab kua roj vanish xws li dej-dispersion acrylic puag yuav tsum tau siv.
Tom qab ziab, cov xim zas xim xim zoo nkauj, uas qhia qhov zoo nkauj ntawm hom xim no. Yog tias xav tau, koj tuaj yeem tsim ntau dua ib lub suab, tab sis ua ntej pib pleev xim, pleev xim qhov sib xyaw kom npaj rau hauv cov xim twg
Qhov no yuav tsis nyuaj, vim tias cov tuam txhab niaj hnub muab cov xim sib txawv: koj tsuas yog yuav tsum xaiv qhov tsim nyog tshaj plaws rau cov xim pleev xim thiab cov kua roj vanish puag. Ntau yam xim hlau xim xim zoo nkauj heev thaum kho cov phab ntsa sab nrauv thiab sab hauv ntawm cov tsev.
Txawm li cas los xij, koj tseem tuaj yeem tsis lees paub lub tswv yim ntawm kev pleev xim rau tus kheej, vim tias muaj ntau yam tshuaj pleev xim rau muag, uas koj tuaj yeem pleev xim phab ntsa nrog cov duab zoo nkauj
Tsis muaj qhov tsawg dua qhov zoo ntawm cov xim raws cov hmoov txhuas yog lawv cov kav ntev. Raws li kev coj ua mus sij hawm ntev ntawm lawv kev siv, cov xim pleev xim los ntawm lawv tsis tas yuav kho thiab rov pleev xim txog li 6-7 xyoo. Txawm li cas los xij, lub sijhawm no tuaj yeem txo qis mus rau 3 xyoos yog tias cov xim pleev xim tas li nrog dej, thaum nyob ntawm cov phab ntsa sab hauv cov tsev nyob, cov xim zoo nkauj zoo nkauj tuaj yeem nyob ntev txog 15 xyoos
Qhov tsis zoo ntawm cov xim no suav nrog qhov tseeb tias txhuas hmoov yog cov nplaim taws heev. Ib qho ntxiv, txawm tias tus txheeb ze tsis muaj tshuaj lom thiab kev nyab xeeb kev nyab xeeb ntawm cov xim tiav, kev nkag los ntawm cov hmoov nyiaj mus rau hauv lub cev ua pa thiab lub ntsws yog qhov txaus ntshai rau tib neeg … Yog li ntawd, pob nrog cov nyiaj yuav tsum tau qhib tsuas yog thaum tsis muaj cov cua ntsawj ntshab hauv chav lossis hauv huab cua nyob hauv qhov chaw qhib, tiv thaiv kab mob ua pa nrog lub tshuab ua pa.
Cov chaw cia khoom thiab cov cai tiv thaiv hluav taws yuav tsum raug saib xyuas thaum tuav cov xim no.
Hauv cov vis dis aus hauv qab no, koj yuav kawm paub yuav ua li cas thiaj paub qhov txawv ntawm PAP-1 thiab PAP-2 txhuas hmoov los ntawm qhov qub.
