Muvengi mukuru wemahwindo nekunze kwemapuranga kubatanidzwa haisi mvura, asi zuva.
Kunyangwe PVC yekubatanidza inofanirwa kurwisa zuva. Kana maPVC profiles akashata, chinojoinha chinogona kuita yero, kuchinjika nekufamba kwenguva - ndosaka mareba akaiswa muPVC joinery - uye owedzera kusasimba.
Nerimwe divi, huni hwakanamirwa kubva kune akati wandei, i.e. laminated profiles, haina dambudziko nekukotama, asi yekunze varnish inofanirwa kunge iri yemhando yepamusoro uye yakanyatsoiswa.
Muvezi wekunze wakaputirwa nei?
Iyo mvura-based varnish yekushandiswa kwekunze inosanganisira yekutanga, i.e. nheyo, iyo ine insulator yekudzivirira kubva mumvura uye zuva uye impregnant inodzivirira kubva kune zvipembenene uye fungi. Kana ikashandiswa, inopinda mukati uye inodzivirira huni. Mamwe maviri kana matatu akaturikidzana majasi epamusoro ane maUV inhibitors akawanda, ayo basa guru nderekudzivirira huni kubva mumwaranzi yeUV.
Varnish yemvura inonatswa nemvura panguva yevarnish, saka kazhinji pane kusava nechokwadi kuti mvura inogona kuisuka pahuni. Icho hachisi chokwadi. Painooma pamusoro pehuni, varnish inova isina mvura uye mvura haichagoni kupinda muhuni.
Sei zuva riri dambudziko rakakura kupfuura mvura?
Mhinduro iri mumutsara wekutanga wechinyorwa chino. Hapana chinodzivirirwa nezuva. Purasitiki inoita brittle uye kutsemuka, rabha zvakare, mavara anopera (rangarira maamburera emahombekombe), kutsemuka kwecanvas, facades kupera …
Sezvimwe zvese, majoini emapuranga anofanirwa kuchengetedzwa zvakaringana kubva kuzuva. Iyi tekinoroji yakaoma nekuti inofanirwa kuchengetedza huni zvakanyanya sezvinobvira, uye panguva imwechete ichibvumira kufema uye, sechinhu chero chipi zvacho, kuwedzera muzhizha uye chibvumirano munguva yechando.
Kana huni huchigadziriswa nemavhanishi, mapeji ekupedzisa anofanira kunge ane UV inhibitors anorwisa zuva. Zuva rinodzipfekedza nekufamba kwenguva, saka zvikamu zvekupedzisira zvinofanirwa kuiswa zvakakora sezvinobvira kuitira kuti pave nemainhibitors akawanda sezvinobvira uye kuitira kuti nzvimbo dzekunze dzikwanise kuramba nemwaranzi yezuva kwenguva yakareba sezvinobvira.
Technologies inosiyana pakati pevagadziri. Mune zvimwe zviitiko, iyo impregnant uye insulator inoshandiswa zvakasiyana, ipapo pende uye chikamu chekupedzisira, asi nheyo yekudzivirira inoramba yakafanana. Tekinoroji dzichiri kupokana nhasi kuti ndeipi tekinoroji iri nani, asi isu hatingaite nazvo pano.
UV inhibitors inodzivirira sei kupera?
UV dziviriro kazhinji iri muchikamu chepamusoro, uye zvishoma munheyo. Varnishers vanoziva kuti jasi repamusoro rine ruvara rweapricot - ndiyo ruvara rwezvidziviriro zvinodzivirira chigadziko uye pende kubva pakuora. Kana iyo layer yaoma, inobuda pachena.
Tekinoroji inoshandiswa mukambani yeSavo Kusić inosanganisira machira akagadzirwa pahwaro hwe pigment ye inorganic mavambo. Dzinoshingirira pamwaranzi yeUV pane ma pigment emuoga anoshandiswa kusvibisa fenicha yemukati.
Mavara emapuranga anogona kusanganiswa here?
Kana ruvara, kureva ruvara rwakagadzirirwa kushandiswa kwemukati, rwakawedzerwa kune varnish yekupedzisira yekushandiswa kwekunze, yaizoshanda kwechinguva, kusvikira UV inhibitors yapera. Ipapo mwaranzi yezuva yaizoita pane pigment ye organic mavambo uye kuputsa ruvara. Zvisungo zvakapetwa kaviri mu organic pigment zvakaputswa nekuita kwemwaranzi yezuva; semuenzaniso, mahogany anova brittle mushure meimwe nguva.
Iyo yakawanda inhibitors inowanikwa muzvikamu zvekupedzisira nokuti ndiyo yekutanga kutarisana nezuva, asi kunewo zvimwe munheyo, i.e. yekutanga. Naizvozvo, iyo isina pamuviri inofanirwa kuitirwa kushandiswa kwekunze. Inofanira kunge iine pigment yezvakabva muorganic, nekuti UV mwaranzi ine simba shoma pairi uye haigone kuodza.
Imwe mhando ye inorganic pigments ma iron oxides, i.e. ngura. Vagadziri vanogadzira ngura nemamwe maitiro etekinoroji uye pane dzimwe tembiricha uye nekudaro vanowana dema dema, ocher, akasiyana mumvuri mutsvuku uye akafanana. Chimiro chemavara anowanikwa nenzira iyi ndechekuti vanochengetedza kugadzikana kwemavara nekufamba kwenguva.
Imwe yeaya akasiyana ndiyo inonzi Bayer feroxy. Iboka rakakosha remakomboni anoshandiswa kugadzira tinting, kongiri, kuvaka uye indasitiri yemapuranga.
Kana mutengi achida ruvara rusiri mune yakajairwa RAL system, asi inoda kuwiriraniswa neiyo iripo fenicha kana facade, mumvuri unofanirwa “kumonyoroka” nemaoko. Varnishers kunyanya havadi basa iri, nokuti rinoda nhamba yakawanda yemvura-based, mafuta-based uye nitro-based shades. Pendi dzakagadzirirwa kushandiswa kwekunze dzinofanira kugara dzakasanganiswa nevanishi yekushandiswa kwekunze, nekuti idzo chete dzine maUV inhibitors ataurwa.
Kune mavara epasirese, asi ayo akagadzirirwa kushandiswa mukati haasati ari ekushandiswa kwekunze. Kana dzikashandiswa panze, ruvara rwunozodzima mushure megore.
Apo mahwindo anobatwa nemvura-based varnishes, UV inhibitors inowanikwa munheyo, asi kunyanya muzvikamu zvekupedzisira nokuti ndiyo yekutanga kudzivirira kubva kuzuva. Ndicho chikonzero chikamu chekupedzisira chevarnish chine “creamy” ruvara, iyo inonyangarika panguva yekuomeswa uye inova pachena, kuitira kuti ruvara runobva kune rumwe rutivi runogona kuonekwa kuburikidza naro.
Nzvimbo yehwindo inokanganisa sei kusimba kwejasi?
Inhibitor kurasikirwa kunonyanya kuonekwa pamahwindo padivi reimba iyo inonyanya kuratidzwa nezuva. Pamahwindo kudivi rekuchamhembe, uko zuva risingasviki, kana pamagonhi epamberi akarembera apo mwaranzi isingadonhe, izvi hazvizoratidzike nenzira imwecheteyo.
Mahwindo emapuranga anofanira kupendwa patsva riini?
Kana mahwindo ari kudivi rezasi, kune zuva rakawanda, mushure memakore mangani anofanira kupendwazve? Hapana mutemo mumwe chete. Zvinoenderana nedivi iro hwindo riripo uye kuti UV radiation inosvika pairi yakawanda sei.
Kana varnish iri yemhando yakanaka uye maitiro akateedzerwa, vagadziri vanowanzopa waranti yemakore mashanu pane varnish. Kune vanogadzira vanopa vimbiso yemakore gumi, asi nemamiriro ezvinhu ekuti mutengi anoshandisa mawoko mutsva wevarnish pahwindo kamwechete kana kaviri pagore.
Sei kuvakwa kwemahwindo uye kushandisa varnish kwakakosha?
Dhigirii yekukuvara kwehwindo mumakore apfuura zvinoenderana nezvakawanda pakuvakwa kwayo. Zvakakosha kuti mahwindo acho aite mutserendende kuitira kuti mvura isarambe paari.
Kana majasi ekupedzisira evarnish asina kushandiswa zvakanaka kana mavhanishi ane zvishoma UV inhibitor, iyo inhibitors ichapera nekukurumidza pasi pesimba reUV uye kuputika kuchaonekwa pavarnish. Kana pasi pehwindo pasisina kona yakakwana, uye mvura yese inodonhedza pasi nepahwindo ikapfuura nepamusoro paro, pendi inozotanga yadonha panzvimbo iyoyo.
Pfupiso
Zuva rinoshanda pavarnish, iyo UV inhibitors inopera uye varnish inotsemuka kana iyo nzvimbo yapera simba. Kana kuvakwa kwehwindo kwakashata, mvura inochengetwa, inopinda nepakatsemuka uye huni dzinosara dzisina kudzivirirwa.
Ndosaka zvichinyanya kukosha kuti mapeji ekupedzisira aiswe kakawanda uye kuti imwe neimwe layer yakakora sezvinobvira. Izvi zvinogona kuitwa chete nevarnish vakanyatsodzidziswa, nokuti varnish iri mumamiriro emvura uye inodonha kana slide kubva pamusoro. Naizvozvo vanishi inoisa vanishi pamuganhu mutete pakati pegumbo rakakora uye rinotsvedza.
Nhanho imwe neimwe inofanira kuremekedzwa, asi pasinei nezvose zviri mukati mekuita, chinhu chevanhu chinoramba chiripo, icho chinotarisa kwete chete kuti chinozadzikiswa, asiwo kuti chinozadzikiswa sei.
Kana kudzivirira zvachose kwekunze kwekubatanidzwa kwakakosha kwauri, tarisa mahwindo emapuranga, magonhi ekumberi kana kutibata nesu kuti quote uye zano.
