Polyurethane yakawanda inoremekedzwa seimwe yeiyo yakasimbiswa zvikuru asi iri nyore-kushandisa-inodzivirira miti inodzivirira. Polyurethanes inowanzowanika mune zvose mafuta-based uye mvura-based formula, uye pane zvisiyana zvidiki pakati pezviviri zviri zviviri nekushanda. Purorethane inoshandiswa inoshandiswa nebrashi, asi panewo kuchenesa mafomu ayo anoshandiswa neregi uye spray inogumisa mumagetsi aerosol.
Pasinei nemhando yaunoshandisa, kana purojekiti yako ichiona zvakanyanya kupfeka uye kubvarura, zvishomanana kupedzisa zvakakodzera sa polyurethane yezvokudzivirira zvepamusoro.
Ndezvipi Zviri Nani-Mafuta-Akatevedzerwa Kana Kuti Inogadziriswa nePururethane?
Chisarudzo chekushandisa mafuta-based or water-based polyurethane kunowanzoenderana nebasa rako uye zvaunofarira. Mafuta-based polyurethanes akangoita nyore kushandisa uye anogona kunge asina kunonoka kupfuura mvura-based form. Vanowanzocheka uye vane zvinyorwa zvakanyanya, zvinoda mahembe maviri kana matatu uko mvura-based poly inogona kudiwa matatu kana ina. Zvisinei, mafuta-based polyurethane apedza anogona kuvhara marashi, uye anotora nguva yakareba kuti aome, izvo zvinogona kuderedza basa rako uye zvichida kuwedzera njodzi yekuwana mishonga kana guruva pakupera kwako isati yaoma.
Mvura-based polyurethane zvinowanika zvakanyanya nokukurumidza, zvishoma nezvishoma kuzvipira, uye zvinonhuwira zvishoma apo zvinoshandiswa kupfuura mafuta-based versions.
Pasi pemvura, mvura-based poly inowedzera kukwidza zviyo zvehuni, inogona kutora watermarks, uye inogona kuva yakanyanyisa kana yakashandiswa pane dzimwe tsvina dzehuni.
Mucherechero mumwe mutengesi. Mafuta-based polyurethane anowedzera huni hunopisa hunikira huni, kunyanya kune zvisikwa zvizere, semuouki machena, maple, kana birch.
Mvura-yakagadzirirwa maitiro yakawanda haisi yechokwadi kana yakajeka. Mvura-yakadzika ine maziso machena anotarisa painoenderera mberi asi inodzoka pachena sezvainooma.
Mazano Okushanda nePolurethane
Chokutanga, svetedza-usambozunungusa-chinogona che polyurethane. Sei? Kugunzva chinogona che polyurethane kunounza mhando dzakawanda mumuchero uchazoonekwa pakupedzisira kwako. Pane kudaro, ingoita kuti chigadzirwa chacho zvinyatsogadzikana asi zvakakwana tisati tashandisa imwe neimwe.
Isa chikamu mumugwagwa wakachena, wakanaka. Polyurethane inotora maawa, kwete mashoma, kuoma; iyo inguva yakawanda yeguruva kugadzirisa kana zvikwata kuti zviwande pasi, zvichishungurudza chigadzirwa chekupedzisira. Izvo zvose mvura-based uye mafuta-based products zvinopa moto wakaoma sezvo ichioma (kunyange zvazvo mafuta-based inosarudzwa zvakanyanya), saka kuvhara kwakakodzera kwakakodzera. Usangoipedzisa basa rako kunze, uko iwe usingakwanisi kudzora guruva, zvibhakera, uye zvimwe kubhururuka-kuparadza.
Zvakanakisisa kushandisa polyurethane kusvika kune zvakadzika (sepamusoro) panopera kuitira kuti kupedzisira kunogona kuzvikwidza uye hazvibviri kudonha. Paunoshandisa polyurethane pazviso zvepamusoro, iwe unogona kukura kana kunomhanya. Deredza dambudziko iri nekushandisa zvipfeko zviduku kana kushanduka kubva pabhesi-yakawanda kusvika pamapuranga kana kupera, zvose zviri zviviri zvinogona kushandiswa mune zvipfeko zvakaonda kwazvo.
Kana ukapedza nekumhanya kana kuputika, edza kuisa shanga kunze kwekuita sanding pakati pemucheka, kana kuti kubvisa zvakanyatsonaka nerasi yakatsvuka (yakateverwa nejecha kune mapepa asina mhosva).
Sezvauri kupedzisa buri jasi idzva munguva yekushanda, chengetedza basa rako nechiedza chakajeka-chiedza. Crouch down saka iwe unoona chiedza chichitarisa kubva pasi. Izvi zvinoratidza kusakwana, zvakadai semakumbo, mabhutsi, marashi akaipa, uye mavara awakangosuwa kana kuti kuguma kwacho kwakanyanya sei. Iwe unokwanisa kugadzirisa matambudziko aya apo kupera kwave kuchine mvura asi kwete kamwe chete iyo inotanga kuisa.
Prepping the Wood
Sezvo nezvose zvinogadzirwa nemiti, migumisiro yakanaka inobva kune yakasviba, yakachena matanda, asi izvi zvinopfurikidza nekupera zvakajeka se polyurethane. Shandisai miti yenyu yehuni ine zvinyorwa 220-grit sandpaper. Nehuni dzehuni dzakasununguka (semuoki, madhishi, kana ruzha), unogona kushandisa huni dzehuni kuzadza pamberi pe polyurethane, kugadzira ye-ultra-smooth smooth surface.
Chenesa huni zvakanyanya kuti ubvise guruva risati rasvika pamberi pejasi rimwe nerimwe re polyurethane, uchishandisa gonhi (kana iripo) uye jira. Iwe unogonawo kushandisa rag yakakanyiwa nemaminerari emhepo (kana mafuta-based poly) kana cheesecloth yakanyoroveswa nedoroid doro (yemvura-based poly).
Kushandisa Mafuta-Based Polyurethane
Iwe unogona kusarudza kuonda mafuta-based polyurethanes nemaminera emidzimu kana naphtha, asi kune zvakawanda zvishandiso, izvi hazvidi; chengetedza mazano ekugadzirisa pane chigadzirwa chemavara. Kunyorera kunogona kubatsira kupedzisira kupfuurira mumashoko akanaka uye nooks nemakwenzi ane zvishoma zvakagadzirwa.
Shandisa mafuta-based poly kushandisa bhii-bristled yakanaka (yakasikwa kana yakagadzirwa) kana bhushi rinoputika. Dzivisa mabhesi asingadhura, sezvo aya anowanzosiya bhururu rakananga. Foam brushes haina mari (uye inoshandiswa) uye inoshanda zvakanaka panzvimbo dzakawanda. Brisle mabhurusisi zviri nani kumativi akaumbwa nemashoko akanaka.
Shambai pa polyurethane kuitira kuti marashiro ebhurosi aenzane nehuyo hwehuni. Shandisa yakakwana, asi isiri yakanyanyisa, jasi yekupedzisa. Pedzisa nzvimbo imwe neimwe kwenguva yakareba, yakananga kurohwa kuti ibudirire kunze kwemavhumu akawanda sezvingaita. Izvo zvishomanana zvakasara mabhudzi zvinowanzopera mukati mechinguva.
Mushure mokunge chipfeko chokutanga chave chaoma chose (maererano nemirayiridzo yegadziri), zvisinganzwisisi jecha nzvimbo yose (zvakare, yakafanana necheyo), uchishandisa 320-grit sandpaper . Iyo polyurethane ichaita jecha nyore nyore, saka chenjerera kuti usasvike necheputi tsvuku uye uparadze tsvina kana huni pasi. Bvisa guruva rose nemucheka uye mucheka usati washandisa wechipiri jasi.
Dzokorora matanho aya kusvikira hunodiwa hwekudzivirirwa hunobudirira. Kuti dzidzivirire, jasi mbiri ndeyaduku, asi pasi uye chero chimwe chinhu chingaona kushanda zvakaoma kana dzimwe nguva unyoro chinofanira kuwana zvingara zvitatu. Nguwo imwe neimwe inoitawo kuti kupedzisa kuve kwakanyarara. Mushure mejasi rako rekupedzisira, unogona kusarudza kubvisa kumagumo ne # 0000 steel wool kune imwe nguva yepamusoro yeheen, inoteverwa nekushandiswa kwekunamatira wax kwekunaka kwakanaka.
Kushandisa Mvura-yakagadzirwa nePururethane
Mvura-based polyurethanes haina kufanana zvakanaka nemafuta-based stains, saka kana iwe uri kushandisa pamusoro peatini iwe unoda "kutasva" iyo yakasvibiswa pasi zvishoma usati washandisa mvura yako-based polyurethane, uchishandisa imwe yakagadzirwa nemucheka wemvere. Sezvo mafuta nemvura hazvisanganisi, izvi zvichabatsira kudzivirira kuti polyurethane irege kuva pamusoro pepamusoro, semvura pane motokari yakangotanga.
Iko inoshandiswa purogiramu yekushandisa yemvura-based poly inofanana neyeiyo mafuta-based. Isa chidimbu chakaipisisa che polyurethane nebharuti yakanaka, pombi yeupfu, kana shati. Shanda pamwe chete nezviyo, uye usapedza kushandisa polyurethane yakawanda kuti urege kukura zviyo.
Iyo jasi yekutanga inofanira kuva yakaoma mukati maawa mashomanana, uye iwe unogona kushandisa rechipiri jasi. Kana ukashandisa nenzira iyi, ungasafanira kuve nejecha pakati pematehwe, sekune mafuta-based poly; chengetedza mazano ekugadzira. Ronga pamusoro pezvipfeko zvitatu zvemvura-based poly pamishonga inoshandiswa zvishoma uye zvigaro zvenguvo zvina pasi uye chero zvidimbu zvinoda kudzivirirwa zvakakwana.
Pukuta-On and Spray Polyurethanes
Chinhu chikuru chakanaka chekuchenesa uye kupora polyurethanes isonda. Zvose izvi zvinogona kushandiswa mumashizha-mashoma anokonzera kushandiswa kwemajoko mashoma mumagetsi nemakona, kana iwe usingashandisi zvakanyanya. Pukuta-panda inoshandiswa nemucheka wakachena, usina ganda. Spray poly inoenderera mberi sepray peype. Vamwe vanogadzira mapuranga vanoda kushandisa mapiritsi emhando yepfeko yepamusoro yepamusoro pamusoro penguvo dzomukati dzowakashongedzana ye polyurethane.
Zvose kupukuta uye kuparadzanisa mafungiro ndiyo mhinduro yakanaka yezvidzidzo zvinonyangadza, semashoko akanaka kana zviso zvepamusoro. Chiedza chekuedza chinoderedza kunyura uye, zvakare, kuvaka. Iko kunotora mwoyo kweiyi miviri yakaipisisa ndeyokuti iwe ungangodaro unoda zvipfeko zvakawanda zvekunaka, kuchengetedza-zvingangove zvishanu kana zvitanhatu zvipfeko panzvimbo yeviri kana katatu nekwakagadzirwa-kazhinji pamapurogiramu.
