Polyurethane yog cov khoom siv zoo tshaj plaws los txhawb kev ua vaj tsev, txhim kho nws cov txuj ci kev ua haujlwm thiab ua kom zoo dua qub. Ib-tivthaiv impregnations raws li nws tau siv los ntawm tus tswv los txhawm rau tiv thaiv ya raws thiab lub zog. Tab sis cov pob zeb ua haujlwm yuav tsum tau tiv thaiv los ntawm qhov tsis zoo ntawm sab nraud ib puag ncig, thiab qhov no xav tau kev sib xyaw ua kom haum haum. Hauv qhov no, nws yuav tsim nyog siv polyurethane primer.

Pros thiab cons

Ua tsaug rau cov txheej txheem ua ntej, lub pob zeb tau txais qhov tsis muaj qhov tsis zoo, ntxiv rau, qhov sib xyaw pab ua kom nplaum nrog cov txheej txheej tom ntej - cov kua roj vanish, pleev xim, pleev xim - ntseeg tau ntau dua.

Cov primers raws li polyurethane tau suav tias yog qhov zoo tshaj plaws rau kev priming vim tias lawv muaj ntau qhov zoo dua li lwm cov qauv

• Polyurethane primer sib xyaw ua ke zoo nrog txhua lub substrates uas muaj cov qauv ntxeem tau nrog kev nqus siab. Yog li ntawd, nws tsis yog siv rau kev ua vaj tsev nkaus xwb, tab sis kuj tseem siv rau ntawm cov ntoo, hlau, cib.
• Polyurethane tuaj yeem siv rau hauv pem teb nrog cua sov hloov.
• Cov khoom siv no tsis yog qhov cuam tshuam, txawm tias muaj cov hmoov av zoo li hais los ntawm lub hauv paus. Tus primer tuaj yeem siv rau qhov ntxaum me ntsis kom huv, thiab cov hmoov av yuav raug khi thaum txheej txheem kho.
• Ib qho tseem ceeb ntawm qhov ua tau zoo ntawm tus primer yog qhov ua tiav ntawm sab hauv thiab sab nrauv tiav.
• Thaum piv nrog cov sib txuas ntawm tib lub hom phiaj, polyurethane yog cov khoom lag luam pheej yig dua. Tau kawg, kev noj nyob ntawm qhov tob uas nws nkag mus rau hauv cov khoom tuab, tab sis nyob rau hauv txhua rooj plaub, los ntawm 1 square meter. m ntawm qhov chaw siv los ntawm 200 txog 500 grams ntawm polyurethane sib xyaw, thiab lwm yam sib xyaw - 2-3 zaug ntxiv.

Nws tuaj yeem raug ntxiv tias vim yog siv polyurethane primer, cov qauv sib txawv ua kom muaj zog dua, qhia qhov muaj zog tiv taus, tiv taus ya raws, ua tau zoo heev nrog rau txheej txheej.

Cov tshuaj sib xyaw ua ke muaj qhov tsis zoo me me, tab sis lawv tsis yog qhov tseem ceeb:

• lub sijhawm ziab rau feem ntau ntawm cov sib xyaw no yog 2 teev, thiab polyurethane yuav siv sijhawm li 3 txog 5 teev los kho;
• daim ntawv thov txheej txheem tau ua tiav ntawm tus kheej, txij li tsis muaj txoj hauv kev siv tshuaj tsuag;
• polyurethane muaj tus nqi qis dua (tab sis peb yuav tsum tsis txhob hnov qab tias txheej txheej yog qhov txawv los ntawm kev hnav zoo thiab ua haujlwm ntev, thiab lub neej ua haujlwm ntev yog tsim nyog tau nyiaj).

Saib

Raws li qib kev ua kom ruaj khov thiab lub hom phiaj, txhua qhov av tau muab faib ua ob pawg loj.

Ib qho kev sib xyaw ua ke

Xws li cov polymer ncaj qha thiab hnyav. Cov muaj pes tsawg leeg muaj cov kua dej sib xws, uas tso cai rau nws siv rau kev ua cov pob zeb, ntoo thiab fibreboard. Vim yog cov qauv ntawm kev sib xyaw, kev nkag mus tob ntawm cov av mus rau hauv cov ntaub ntawv no tau ua tiav, qib kev pom tau zoo thiab txhim khu kev ntseeg mus rau qhov ua tiav zaum kawg rau yav tom ntej.

Ob-tivthaiv primer

Nws tau tsim nyob rau hauv daim ntawv ntawm ob qhov sib cais sib xyaw - tawv tawv thiab sib xyaw ua ke primer - hauv cov thawv sib txawv. Lawv tau sib xyaw ua ntej siv. Tab sis ntau yam no tsis yog yas, txawm hais tias nws muaj zog dua. Qhov tseeb, qhov no tsis tiv thaiv nws los ntawm kev siv rau hauv pem teb pob zeb tsim los rau qhov hnyav. Kev sib xyaw ua ob ntu tsis siv rau MDF thiab ntoo, tab sis lawv tsim nyog rau cov hlau, vim tias lawv muaj zinc, uas tiv thaiv cov khoom los ntawm kev xeb. Rau hauv qab daus, chav dai khaub ncaws thiab chaw tso tsheb, xws li cov subtype ntawm primer li primer-enamel, uas hloov pauv cov xim, yog qhov cuam tshuam.

Lwm hom polyurethane-based primers tseem muaj cov khoom muaj txiaj ntsig thiab yam ntxwv zoo. Wb sau lawv.

Alkyd primers . Lawv xav tau ntoo hauv txoj kev zoo. Lawv tiv thaiv cov ntoo ntawm cov xim tsis sib xws, nws ua kom tsaus ntuj, tuaj yeem siv ua cov pleev xim yog tias nws yog cov xim pleev xim.

Cov nplaum . Lawv roughen txheej saum npoo kom zoo adhesion rau polished qhob substrates.

Acrylic primers . Lawv tau siv rau kev ua ntoo thiab pob zeb ua ke, muab kev sib sib zog nqus ntawm cov qauv ntxeem tau, txhawb qib.

Epoxy enamels, xim thiab primers . Ntxiv dag zog rau cov pob zeb thiab hlau, thiab tseem tsim cov txheej tiv thaiv ntawm lawv saum npoo.

Ua ntej txhim kho cov phab ntsa ntub dej lossis cov nplais pobzeb, nws yog qhov zoo tshaj los npog lub hauv paus pob zeb nrog cov txheej txheem tshwj xeeb hu ua kev sib cuag .

Qhov nrov tshaj plaws yog cov txheej txheem polyurethane hauv qab no

" Hauv av 1101 " - ib feem khoom lag luam nrog rau suav nrog cov organic hnyav. Nws tau siv rau ntawm pob zeb, ntoo, plaster, ua rau muaj kev tiv thaiv ntau ntxiv, hnav tsis kam thiab ua rau cov khoom siv tiav. Qhov muaj pes tsawg leeg ntawm cov khoom muaj kev nyab xeeb rau tib neeg kev noj qab haus huv, yooj yim thov.

Primer-primer "Primer PU 01 " - kev sib xyaw ua ke thoob ntiaj teb, tsim nyog rau ib qho substrates, ua tau zoo tshem tawm cov nplaim ntawm cov qauv, nce lawv lub zog, qhuav sai.

Txhua tus neeg sawv cev priming tau muab cais ua cov qauv thiab nkag mus tob.

Cov ntawv thov

Polyurethane primer tuaj yeem siv txhua qhov chaw ua vaj tse, hlau, ntoo, cib thiab lwm yam khoom siv, xav tau kev sib dhos thiab pleev xim nrog cov xim thiab cov khoom siv kua roj vanish.

• Polyurethane-based primer yog qhov zoo rau kev kho cov plag tsev thiab phab ntsa hauv cov tsev nyob thiab cov tsev tsim khoom. Tshwj xeeb tshaj yog qhov tom ntej tha xim, plasterboard lossis pobzeb tso yog pom.
• Cov khoom siv polyurethane tau siv los ua kom lub neej muaj sia nyob ntawm lub tsev, suav nrog cov qauv ntoo, ntxiv rau phab ntsa thiab hauv paus hauv paus ua los ntawm ntoo.
• Lub hauv paus tau ua tiav siv los kho MDF cov rooj tog zaum ua ntej polishing thiab pleev xim rau lawv.
• Cov khoom sib xyaw yog siv los ntxiv dag zog rau hauv pem teb hauv cov tsev pej xeem nrog cov khoom siv siab.
• Hauv kev cob qhia tsim khoom, av yog qhov tsim nyog rau kev ua vaj tse txhawm rau tshem tawm cov plua plav tsis xav tau ntawm nws qhov chaw. Tsis tas li ntawd, polyurethane ua lub tsho tiv no.

Siv cov hlau ua ntej, koj tuaj yeem kho lossis tiv thaiv cov khoom ua los ntawm galvanized, ferrous hlau, aluminium thiab steel, txo qis kev hem thawj ntawm xeb ntawm ib qho qauv hlau sab hauv thiab sab nraum chav.

Yuav xaiv li cas?

Qhov kev xaiv raug ntawm primer yog tus yuam sij rau kev ua tiav qib siab, ua kom siab thiab tiv thaiv siab tshaj plaws rau txhua tus qauv. Thaum yuav cov primers, koj yuav tsum ua raws li tus lej xav tau rau kev sib xyaw.

• Hom khoom yuav tsum tau ua ntej yuav tsum raug coj mus rau hauv tus account. Qee qhov ntau yam tau tsim tshwj xeeb rau MDF, hlau lossis pob zeb ua ke.
• Rau thaj chaw nyob, koj yuav tsum xaiv tsuas yog cov khoom muaj kev nyab xeeb uas tsis muaj cov tshuaj lom ntxiv uas tuaj yeem tso pa phem. Acrylic thiab polyurethane cov khoom tsim nyog tshaj rau qhov no.
• Nyob ntawm qhov chaw uas cov txheej txheem yuav tsum tau kho (nyob hauv tsev lossis sab nraum zoov), koj tuaj yeem xaiv cov txheej txheem ua ntej lossis sib xyaw ua haujlwm sab nraum zoov.
• Ib qho av zoo yuav tsum muaj cov tshuaj tua kab thiab tshuaj tua kab mob. Yog tias nws yog qhov tsim nyog los ua txheej txheej ntawm cov hlau, tom qab ntawd kev tiv thaiv kev tiv thaiv kev xeb yog qhov tseem ceeb, uas yog, cov txheej txheem yuav tsum suav nrog cov khoom muaj nplua nuj nyob hauv zinc.

Cov kws tshaj lij pom zoo kom yuav tsuas yog cov tshuaj tshiab los ntawm cov tuam txhab muaj npe nrov . Hauv qhov no, muaj peev xwm ua kom rov zoo dua qub lossis tsim cov txheej tshiab ntawm cov nplaim los ntawm cov khoom sib txawv tau muab.
