Tus yeeb ncuab loj tshaj plaws ntawm qhov rais thiab sab nrauv ntoo joinery tsis yog dej, tab sis lub hnub**.
Txawm tias PVC joinery yuav tsum tawm tsam lub hnub. Yog tias PVC cov ntaub ntawv tsis zoo, cov khoom siv tuaj yeem tig daj, ua rau lub sijhawm - yog vim li cas cov rebars tau muab tso rau hauv PVC joinery - thiab ua rau tsis yooj yim dua.
Ntawm qhov tod tes, ntoo nplaum los ntawm ob peb txheej, piv txwv li laminated profiles, tsis muaj teeb meem nrog dabtsi yog khoov, tab sis cov kua roj vanish sab nrauv yuav tsum yog cov khoom zoo thiab siv tau zoo.
Tus kws ntoo sab nrauv yog dab tsi?
Cov kua roj vanish rau sab nraud yog siv los ntawm thawj txheej, piv txwv li lub hauv paus, uas muaj cov insulator rau kev tiv thaiv los ntawm dej thiab lub hnub thiab impregnant uas tiv thaiv kab thiab fungi. Thaum thov, lawv nkag mus tob thiab tiv thaiv ntoo. Lwm ob los yog peb txheej yog topcoats uas muaj feem ntau UV inhibitors, nws lub luag hauj lwm tseem ceeb yog los tiv thaiv ntoo los ntawm UV rays.
Dej-raws li cov kua roj vanish yog diluted nrog dej thaum lub sij hawm varnishing, yog li feem ntau tsis ntseeg tias nag tuaj yeem ntxuav nws tawm ntawm ntoo. Qhov ntawd tsis muaj tseeb. Thaum nws qhuav ntawm cov ntoo, cov kua roj vanish yuav tsis muaj dej thiab dej tsis tuaj yeem nkag mus rau hauv ntoo.
Vim li cas lub hnub thiaj li teeb meem loj dua dej?
Cov lus teb yog nyob rau hauv thawj kab lus ntawm cov ntawv no. Tsis muaj dab tsi tiv thaiv lub hnub. Yas ua nkig thiab tawg, roj hmab ib yam nkaus, xim ploj (nco ntsoov cov kaus mom puam), canvas tawg, facades ploj …
Zoo li txhua yam, cov ntoo ntoo yuav tsum muaj kev tiv thaiv zoo los ntawm lub hnub. Cov tshuab no yog qhov nyuaj vim tias nws yuav tsum tiv thaiv ntoo kom ntau li ntau tau, thiab tib lub sijhawm cia nws ua pa thiab, zoo li txhua yam khoom siv, nthuav dav rau lub caij ntuj sov thiab cog lus rau lub caij ntuj no.
Thaum ntoo raug kho nrog cov kua roj vanish, cov txheej txheej tiav yuav tsum muaj UV inhibitors uas tawm tsam lub hnub. Lub hnub hnav lawv nyob rau lub sijhawm, yog li cov khaubncaws sab nraud povtseg zaum kawg yuav tsum tau thov kom tuab li sai tau kom muaj ntau yam inhibitors li sai tau thiab kom cov chaw sab nrauv tuaj yeem tiv thaiv hnub ci hluav taws xob ntev li ntev tau.
Technologies txawv ntawm cov tuam ntxhab. Qee zaum, cov impregnant thiab insulator yog siv cais, tom qab ntawd cov xim thiab cov txheej txheem kawg, tab sis lub hauv paus ntsiab lus ntawm kev tiv thaiv tseem zoo li qub. Cov kws tshaj lij niaj hnub no tseem sib cav txog qhov twg technology zoo dua, tab sis peb yuav tsis kam nrog qhov ntawd ntawm no.
UV inhibitors tiv thaiv qhov kawg li cas?
UV tiv thaiv feem ntau yog nyob rau saum txheej, thiab tsawg dua hauv lub hauv paus. Varnishers paub tias lub tsho tiv no saum toj kawg nkaus muaj xim apricot - uas yog xim ntawm cov inhibitors uas tiv thaiv lub hauv paus thiab xim los ntawm kev lwj. Thaum cov txheej dries, nws dhau los ua pob tshab.
Cov thev naus laus zis siv hauv lub tuam txhab Savo Kusić muaj cov txheej txheem ua los ntawm cov xim ntawm cov hauv paus chiv keeb. Lawv muaj peev xwm tiv taus UV hluav taws xob ntau dua li cov xim ntawm cov organic chiv siv rau cov rooj tog zaum sab hauv.
Cov xim ntoo puas tuaj yeem sib xyaw?
Yog tias xim, piv txwv li, ib qho stain npaj rau kev siv sab hauv, tau ntxiv rau cov kua roj vanish zaum kawg rau kev siv sab nraud, nws yuav ua haujlwm ib ntus, kom txog rau thaum UV inhibitors hnav. Tom qab ntawd lub hnub lub rays yuav ua rau cov xim ntawm cov organic keeb kwm thiab zom cov xim. Ob daim ntawv cog lus nyob rau hauv cov organic pigment yog tawg los ntawm kev txiav txim ntawm lub hnub rays; Piv txwv li, mahogany ua nkig tom qab ib lub sijhawm.
Cov inhibitors feem ntau pom nyob rau hauv cov txheej txheem kawg vim lawv yog thawj zaug raug rau lub hnub, tab sis kuj muaj qee qhov hauv lub hauv paus, piv txwv li thawj txheej. Yog li ntawd, lub impregnant yuav tsum tau npaj rau kev siv sab nraud. Nws yuav tsum muaj cov pigments ntawm inorganic keeb kwm, vim hais tias UV hluav taws xob muaj zog ntau zog rau lawv thiab tsis tuaj yeem decompose lawv.
Ib hom inorganic pigments yog hlau oxides, piv txwv li xeb. Cov neeg tsim khoom ua cov txheej txheem xeb nrog qee cov txheej txheem thev naus laus zis thiab ntawm qee qhov kub thiab yog li tau txais cov xim dub, ocher, cov xim sib txawv ntawm cov xim liab thiab cov kev hloov pauv zoo sib xws. Cov yam ntxwv ntawm cov pigments tau los ntawm cov txheej txheem no yog tias lawv tswj cov xim ruaj khov nyob rau lub sijhawm.
Ib qho ntawm cov kev hloov pauv no yog hu ua Bayer feroxy. Nws yog ib pab pawg tshwj xeeb ntawm cov tebchaw siv rau finer tinting, pob zeb, kev tsim kho thiab kev lag luam ntoo.
Thaum tus neeg siv khoom xav tau cov xim uas tsis yog nyob rau hauv tus qauv RAL system, tab sis xav tau kev sib koom tes nrog cov rooj tog zaum lossis facade, qhov ntxoov ntxoo yuav tsum tau “twisted” manually. Varnishers tshwj xeeb tshaj yog tsis nyiam txoj haujlwm no, vim tias nws yuav tsum muaj ntau cov dej-raws li, roj-raws li thiab nitro-based ntxoov. Cov xim uas npaj rau kev siv sab nraud yuav tsum tau muab sib xyaw nrog cov kua roj vanish rau kev siv sab nraud, vim tias tsuas yog cov uas tau hais txog UV inhibitors.
Muaj universal stains, tab sis cov uas npaj rau kev siv sab hauv yog tsis muaj txhais tau tias rau kev siv sab nraud. Yog tias lawv siv sab nraud, cov xim yuav ploj tom qab ib xyoos.
Thaum lub qhov rais raug kho nrog cov kua roj vanish, UV inhibitors pom nyob rau hauv lub hauv paus, tab sis feem ntau nyob rau hauv cov khaubncaws sab nraud povtseg zaum kawg vim lawv yog thawj tiv thaiv los ntawm lub hnub. Tias yog vim li cas cov txheej txheem kawg ntawm cov kua roj vanish muaj xim “creamy”, uas ploj thaum lub sij hawm ziab thiab ua pob tshab, kom cov xim ntawm thawj txheej tuaj yeem pom los ntawm nws.
Txoj hauj lwm ntawm lub qhov rais cuam tshuam li cas ntawm cov txheej txheem durability?
Inhibitor poob yog pom ntau dua ntawm qhov rais ntawm sab ntawm lub tsev uas raug tshav ntuj ntau dua. Nyob rau ntawm qhov rais nyob rau sab qaum teb, qhov twg lub hnub tsis ncav cuag, los yog nyob rau hauv recessed pem hauv ntej lub qhov rooj uas lub rays tsis poob, cov nyhuv no yuav tsis tshwm sim nyob rau hauv tib txoj kev.
Thaum twg cov qhov rais yuav tsum tau repainted?
Yog lub qhov rais nyob rau sab qab teb, qhov twg muaj hnub ntau dua, tom qab pes tsawg xyoo lawv yuav tsum tau pleev xim dua? Tsis muaj ib txoj cai. Nws nyob ntawm sab ntawm lub qhov rais thiab ntau npaum li cas UV hluav taws xob ncav cuag nws.
Yog cov kua roj vanish zoo thiab cov txheej txheem ua raws, cov tuam txhab feem ntau muab tsib xyoos lav rau cov kua roj vanish. Muaj cov chaw tsim khoom uas muab kev lees paub txog li kaum xyoo, tab sis nrog cov xwm txheej uas tus neeg siv khoom siv cov txheej txheem tshiab ntawm cov kua roj vanish rau lub qhov rais ib zaug lossis ob zaug hauv ib xyoos.
Vim li cas qhov rais kev tsim kho thiab cov kua roj vanish tseem ceeb?
Qhov kev puas tsuaj ntawm qhov rais nyob rau ntau xyoo nyob ntawm kev tsim kho nws tus kheej. Nws yog ib qho tseem ceeb uas qhov chaw qhov rais yog qhov slopes kom cov dej tsis nyob ntawm lawv.
Yog tias cov tsho tiv no zaum kawg ntawm cov kua roj vanish tsis zoo los yog cov kua roj vanish muaj me ntsis UV inhibitor, cov inhibitors yuav hnav sai sai nyob rau hauv lub zog ntawm UV thiab cov kab nrib pleb yuav tshwm rau ntawm cov kua roj vanish. Yog tias qhov molding hauv qab ntawm lub qhov rais tsis muaj lub kaum sab xis txaus, thiab tag nrho cov dej ntws los ntawm lub qhov rais hla nws, cov xim yuav poob rau hauv qhov chaw ua ntej.
Summary
Lub hnub ua rau cov kua roj vanish, cov UV inhibitors hnav tawm thiab cov kua roj vanish tawg thaum cov nplaim tsis muaj zog. Yog tias qhov kev tsim kho ntawm lub qhov rais tsis zoo, dej tau khaws cia, nkag mus los ntawm cov kab nrib pleb thiab cov ntoo zoo li tsis muaj kev tiv thaiv.
Yog vim li cas nws tseem ceeb tshaj plaws uas cov txheej txheem kawg tau siv ob peb zaug thiab txhua txheej yog tuab li ntau tau. Qhov no tsuas yog ua tau los ntawm cov kua roj vanish uas tau kawm zoo, vim tias cov kua roj vanish nyob hauv lub xeev cov kua thiab ntws los yog swb tawm ntawm qhov chaw. Cov kua roj vanish yog li siv cov kua roj vanish rau ntawm tus ciam teb nyias ntawm ib txheej tuab txaus thiab ntog.
Txhua kauj ruam yuav tsum tau hwm, tab sis txawm tias tag nrho cov ntsiab lus hauv cov txheej txheem, tib neeg qhov tseem ceeb tseem nyob, uas txiav txim siab tsis yog tias lawv ua tiav, tab sis kuj tseem ua tiav lawv li cas.
