Ua ntej pleev xim, txhua yam kev tsim vaj tsev yuav tsum tau ua ntej. Kev sib xyaw rau qhov no tuaj yeem siv ntau txoj hauv kev. Piv txwv li, feem ntau cov txheej txheem ntawm cov tsev thiab cov vaj tse raug kho nrog dej-dispersion primer ua ntej pleev xim. txhais tau tias ntawm ntau yam no yog pheej yig thiab tsim ib tug txhim khu kev qha, zoo adhesion txheej ntawm cov chaw ntawm cov khoom sib txawv thiab cov ntaub ntawv pleev xim.
Kev piav qhia dav dav
Tus qauv tsim, cov primers no yog qhov tawg ntawm acrylate polymers hauv dej. Raws li tuaj yeem txiav txim los ntawm lawv lub npe, cov khoom lag luam no yog tsim los ntawm kev siv tshuaj hnyav. Lawv raug tsim los ntawm cov dej zoo tib yam.
Qhov tseeb, cov primers no yog cov kua dej uas muaj ntau ntawm cov khoom siv hluav taws xob tsis zoo. Tom qab cov dej dries, cov tom kawg nyob rau saum npoo, polymerize thiab tsim ib tug nyias, ruaj zaj duab xis.
txiaj ntsig ntawm kev siv
Qhov txiaj ntsig tseem ceeb ntawm dej-dispersion primerssuav tias yog tsis muaj teeb meem kiag li. Tsis zoo li cov formulations npaj los ntawm cov tshuaj solvents, hom khoom no tsis emit tej yam tsis kaj siab tsw thaum tov los yog siv rau qhov chaw. Qhov tsuas yog qhov uas tus tswv ua haujlwm nrog cov av zoo li no yuav tsum sim kom tsis txhob tau txais nws cov tee rau hauv nws lub qhov muag. Nws tsis yog qhov tsim nyog los qhib qhov rais thiab qhov rooj thaum siv cov khoom sib xyaw hauv tsev.
Qhov zoo tsis txaus ntseeg ntawm primers ntawm hom no kuj yog qhov yooj yim ntawm kev siv thiab tsis-combustibility. Xws li kev sib xyaw yog siv rau cov phab ntsa siv cov xim pleev xim rau cov menyuam lossis txhuam. Ua hauj lwm ntawm kev kho deg nrog lawv cov kev siv yuav ua tau sai heev txawm hais tias nws yog tsim nyog rau lub tsho tiv no nyob rau hauv ob txheej. Cov primers no qhuav sai heev. Txij li cov khoom no tau npaj los ntawm dej, lawv tsis tuaj yeem hlawv hauv txoj cai.
Tau kawg, qhov zoo ntawm cov primers xws li lawv cov txiaj ntsig. Zaj movie lawv tsim yog lub hauv paus zoo rau cov xim.
Dab tsi yog qhov tsis zoo?
Tseem xyaum tsis muaj qhov tsis zoo ntawm primers ntawm hom no. Plasterers-painters xav txog qee qhov tsis zoo ntawm cov nyiaj no tsuas yog tso cai rau khaws cia tsuas yog qhov zoo, zoo dua li chav tsev kub. Thaum khov, dej-dispersion primers poob lawv qhov zoo. Lawv kuj yuav tsum raug thauj raws li cov cai.
Nws tuaj yeem siv cov khoom ntawm pab pawg no rau ntawm qhov chaw tsuas yog ntawm qhov kub ntawm +5 ˚С thiab ntawm huab cua av noo txog 80%. Nyob rau hauv lwm yam mob, lub dispersion zaj duab xis ntawm lub enclosing lugnws tsuas yuav tsis tsim. Qhov no, tau kawg, kuj tuaj yeem suav tias yog qee qhov tsis zoo ntawm ntau yam no.
Ib qho tshwj xeeb ntawm cov dej-dispersion primers yog, ntawm lwm yam, uas lawv, tsis zoo li tshuaj muaj pes tsawg leeg, tsim ib zaj duab xis nyias heev ntawm qhov chaw. Yog li ntawd, npaj cov phab ntsa, qab nthab thiab facades ua ntej siv kom zoo zoo li sai tau.
muaj ntau yam dab tsi?
Tag nrho tam sim no tsim cov dej-dispersion primers muab faib ua peb hom:
- polyvinyl acetate - qhov pheej yig tshaj plaws, tsis zoo rau cov av noo siab;
- butadiene styrene - tsis kim dhau, tsis ntshai ntawm ya raws, tab sis tsis tshwj xeeb te-resistant;
- acrylic - kim tshaj plaws, ntau yam, zoo zam qhov kub thiab av noo siab.
Nws yog hom nyiaj kawg uas yog nrov tshaj plaws ntawm cov plasterers-painters. Acrylic water-dispersion primers yog, ntawm lwm yam, tiv taus abrasion thiab hloov tau.
Raws li qhov kev siv, cov nyiaj ntawm hom no tau muab faib ua:
- universal;
- adhesive;
- dub tob;
- tiv thaiv corrosion.
Technical yam ntxwv ntawm dej dispersion primer
Tsim cov khoom sib xws ntawm lub tuam txhab hauv tebchaws Russia, suav nrog cov qauv uas tau teev tseg los ntawm GOST R 52020-2003. Cov khoom ntawm hom no muab tso rau hauv kev ua lag luamyuav tsum ua kom tau raws li cov cai hauv qab no:
- tus naj npawb ntawm cov khoom tsis hloov pauv - tsis ntau tshaj 28;
- ziab nrawm - mus txog 14 teev;
- density - 1 kg/dm3.
Thaum yuav cov khoom no, koj yuav tsum tau saib qhov ntsuas li kev noj. Rau cov dej-dispersion primers, raws li cov kev cai, tus nqi no yuav tsum yog 0.1-0.6 l / m2.
thaj chaw thov
Ib qho ntawm qhov zoo ntawm cov khoom siv dej-dispersion yog lawv ntau yam. Raws li cov kev cai, nws raug tso cai rau coated nto nrog xws li compositions ua ntej painting:
- mineral - pob zeb, blocks, cib, plasters;
- ntoo, OSB, chipboard, thiab lwm yam;
- GKL;
- metal;
- plastic.
Cov khoom siv dav dav siv rau txhua qhov chaw no. Nyob rau tib lub sijhawm, kev npaj cov ntaub ntawv zoo li no ua ntej dyeing nrog kev siv cov dej-dispersion agents yog qhov zoo heev.
Universal formulations
Primers ntawm no ntau yam yog feem ntau siv rau kev kho ua ntej ntawm plastered, cib los yog plasterboard nto.
txhais tau tias hom no tuaj yeem txhim kho qhov adhesion ntawm txhua yam khoom thiab tib lub sijhawm ntxiv dag zog rau lawv. Tsis tas li ntawd, xws li primers yog txawv los ntawm antiseptic zog. Ntawd yog, cov fungus ntawm qhov chaw thaum lawv tau siv tom qab, piv txwv li, tsis tsim. Raws li, cov phab ntsa lawv tus kheej, kho nrog xws li ib tug muaj pes tsawg leeg ua ntej pleev xim, muaj peev xwm nyob ntev li ntev tau.
Primers ntawm pab pawg no yog siv rau kev kho mob ntawm qhov chaw du heev. Nws tuaj yeem yog, piv txwv li, pob zeb lossis yas. Lawv kuj siv tau rau ceramics, iav, pleev xim rau.
Nws yog hom no uas nrov heev ntawm cov plasterers-painters thiab cov kws ua haujlwm hauv tsev dej-dispersion primer "Concrete Contact". Txhais tau hais tias hom no muaj peev xwm ua kom cov nplaum nplaum ntawm qhov chaw du. Cov xim ntawm cov ntaub ntawv no tom qab nteg nyob rau hauv ib txheej txawm thiab kav ntev heev.
Cov cuab yeej nkag mus tob
Cov khoom ntawm hom no feem ntau siv los ua cov txheej txheem xoob xoob - cellular pob zeb, ntoo, qub plastered. Ib qho tshwj xeeb ntawm dej-dispersion sib sib zog nqus nqus primers yog, ntawm lwm yam, uas lawv tau absorbed rau hauv cov qauv saum npoo los ntawm ob peb millimeters. Nyob rau tib lub sij hawm, xws li cov tebchaw lo ua ke lub pores ntawm cov khoom, ho nce nws lub zog. Tom qab ntawd, plaster lossis pob zeb kho hauv txoj kev no tsis tawg.
Anti-corrosion agents
Primers ntawm hom no muaj cov tshuaj uas tuaj yeem tiv thaiv xeb. Cov dej-dispersion agents ntawm pab pawg no yog siv los kho cov hlau nto. Raws li cov kev cai, lawv tuaj yeem siv rau kev npaj ua ntej ntawm txhua yam ntaub ntawv ntawm hom no. Cov hlau uas tsis yog-ferrous thiab ferrous tuaj yeem kho nrog cov primers.
Yog tias tsim nyog, cov nyiaj no, tau kawg,tuaj yeem siv rau lwm qhov chaw. Piv txwv li, plaster thiab putty feem ntau yog kho nrog anti-corrosion primers. Cov nplaum nplaum nyob rau hauv rooj plaub no kuj dhau los ua qhov zoo heev.
Technology of use
Kev siv dej-dispersion primers rau ntawm qhov chaw yog qhov yooj yim heev. Kev siv thev naus laus zis suav nrog peb theem tseem ceeb:
- nplua nuj;
- npaj cov primer nws tus kheej;
- daim ntawv thov tiag tiag.
Phab ntsa thiab qab nthab yog ntxuav kom huv si ntawm cov av ua ntej priming, leveled thiab qhuav yog tias tsim nyog. Cov muaj pes tsawg leeg nws tus kheej yog shaken ua ntej thov. Yog tias nws khov heev, ntxiv dej rau nws. Siv cov primer rau saum npoo nrog cov menyuam hauv ib txheej nyias nyias. Kev rub cov khoom no rau hauv cov phab ntsa yuav tsum ua kom zoo li sai tau.
Qhov no yog li cas cov chaw kho mob ua ntej pleev xim, piv txwv li, siv Birs Beton Tiv tauj dej-dispersion primer, anti-corrosion compounds, tob tob thiab lwm yam.
