Isitha esikhulu samafasitela nezinto zokuhlanganisa zokhuni zangaphandle akuwona amanzi, kodwa yi-langa.
Ngisho ne-PVC yokuhlanganisa kufanele ilwe nelanga. Uma amaphrofayili e-PVC emabi, okuhlanganisayo kungaphenduka kubephuzi, kugwetshwe ngokuhamba kwesikhathi — yingakho ama-rebar afakwa endaweni yokuhlanganisa ye-PVC — futhi abe ntekenteke kakhulu.
Ngakolunye uhlangothi, ukhuni olunanyathiselwe kusuka ezingqimbeni ezimbalwa, okungukuthi amaphrofayili ane-laminated, alunankinga nokugoba, kodwa ukuvanisha kwangaphandle kufanele kube kwekhwalithi ephezulu futhi kusetshenziswe ngendlela efanele.
Ingaphandle lendawo yokubaza embozwe ngani?
I-varnish esekelwe emanzini yokusetshenziswa kwangaphandle iqukethe isendlalelo sokuqala, okungukuthi isisekelo, esiqukethe i-insulator yokuvikela emanzini kanye nelanga kanye ne-impregnant evikela izinambuzane nesikhunta. Uma zisetshenziswa, zingena zijule futhi zivikele ukhuni. Ezinye izingqimba ezimbili noma ezintathu amajazi aphezulu aqukethe ama-UV inhibitor amaningi, umsebenzi oyinhloko owukuvikela ukhuni emisebeni ye-UV.
I-varnish esekelwe emanzini ihlanjululwe ngamanzi ngesikhathi sokugcoba, ngakho-ke kuvame ukungabaza ukuthi imvula ingayigeza izinkuni. Lokho akulona iqiniso. Ngokushesha nje lapho isomile ebusweni bokhuni, i-varnish iba manzi futhi amanzi awasakwazi ukungena okhunini.
Kungani ilanga liyinkinga enkulu kunamanzi?
Impendulo isemushweni wokuqala walo mbhalo. Akukho lutho olungavikelekile elangeni. Ipulasitiki iba brittle futhi iqhekeke, irabha nayo, imibala iyafiphala (khumbula izambulela zasolwandle), amaseyili ayaqhekeka, ama-facade ayafiphala…
Njengayo yonke enye into, indawo yokuhlanganisa yokhuni kufanele ivikelwe ngokwanele elangeni. Lobu buchwepheshe buyinkimbinkimbi ngoba kufanele buvikele ukhuni ngangokunokwenzeka, futhi ngesikhathi esifanayo buvumele ukuba buphefumule futhi, njenganoma iyiphi into, bunwebe ehlobo futhi bube nenkontileka ebusika.
Uma ukhuni luphathwa ngamavanisha, izendlalelo zokuqedela kufanele zibe nama-UV inhibitors alwa nelanga. Ilanga liyawaguga ngokuhamba kwesikhathi, ngakho-ke izingqimba zokugcina kufanele zisetshenziswe njengogqinsi ngangokunokwenzeka ukuze kube nama-inhibitor amaningi ngangokunokwenzeka futhi ukuze izindawo ezingaphandle zikwazi ukumelana nemisebe yelanga isikhathi eside ngangokunokwenzeka.
Ubuchwepheshe buyahluka phakathi kwabakhiqizi. Kwezinye izimo, i-impregnant ne-insulator isetshenziswa ngokwehlukana, khona-ke upende kanye nesendlalelo sokugcina, kodwa isimiso sokuvikela sihlala sinjalo. Ochwepheshe basaphikisana nanamuhla mayelana nokuthi ibuphi ubuchwepheshe obungcono, kodwa ngeke sibhekane nalokho lapha.
Ama-UV inhibitors avikela kanjani isiphetho?
Ukuvikela kwe-UV ikakhulukazi kusendlalelo esiphezulu, futhi kuncane kusisekelo. Ama-varnishers ayazi ukuthi ijazi eliphezulu linombala we-apricot - lowo ngumbala we-inhibitors ovikela isisekelo nopende ekuboleni. Uma ungqimba loma, luba sobala ngokuphelele.
Ubuchwepheshe obusetshenziswa enkampanini ye-Savo Kusić bubandakanya ukumbozwa okwenziwe ngesisekelo sombala wemvelaphi ye-inorganic. Zimelana kakhulu nemisebe ye-UV kunemibala yemvelo esetshenziselwa ukungcolisa ifenisha yangaphakathi.
Ingabe imibala yokhuni ingaxutshwa?
Uma umbala, i.e. ibala elihloselwe ukusetshenziswa kwangaphakathi, ungezwe kuvanisha yokugcina ukuze usetshenziswe ngaphandle, uzosebenza isikhashana, kuze kuguge ama-UV inhibitor. Khona-ke imisebe yelanga yayizosebenza kumbala wemvelaphi yezinto eziphilayo futhi iwuphule umbala. Izibopho eziphindwe kabili kumbala wemvelo ziphulwa isenzo semisebe yelanga; isibonelo, i-mahogany iba brittle ngemva kwesikhathi esithile.
Ama-inhibitor amaningi atholakala ezingqimbeni zokugcina ngenxa yokuthi yizona ezokuqala ezichayeka elangeni, kodwa kukhona futhi kusisekelo, okungukuthi isendlalelo sokuqala. Ngakho-ke, okhulelwe kufanele ahloselwe ukusetshenziswa kwangaphandle. Kumelwe iqukathe umbala wemvelaphi ye-inorganic, ngoba imisebe ye-UV inomphumela obuthaka kakhulu kuzo futhi ayikwazi ukuyibolisa.
Olunye uhlobo lwemibala ye-inorganic ama-iron oxides, okungukuthi ukugqwala. Abakhiqizi bacubungula ukugqwala ngezinqubo ezithile zobuchwepheshe kanye namazinga okushisa athile futhi ngaleyo ndlela bathola umbala omnyama, i-ocher, i-shades ehlukene ebomvu nokuhlukahluka okufanayo. Isici sezingulube ezitholwe yile nqubo ukuthi zigcina ukuqina kombala ngokuhamba kwesikhathi.
Okunye kwalezo zinhlobonhlobo yilokho okubizwa nge-Bayer feroxy. Iqembu elikhethekile lezinhlanganisela ezisetshenziselwa ukuthayela okuhle, ukhonkolo, ukwakhiwa kanye nemboni yezinkuni.
Lapho iklayenti lidinga umbala ongekho ohlelweni olujwayelekile lwe-RAL, kodwa udinga ukuhlanganiswa nefenisha ekhona noma i-facade, umthunzi kufanele “usonte” ngesandla. Ama-varnishers ikakhulukazi awawuthandi lo msebenzi, ngoba udinga inani elikhulu lama-shades asekelwe emanzini, asekelwe ngamafutha kanye ne-nitro. Amapende ahloselwe ukusetshenziswa ngaphandle kufanele ngaso sonke isikhathi ahlanganiswe ne-varnish ukuze asetshenziswe ngaphandle, ngoba yilawo kuphela aqukethe ama-UV inhibitors ashiwo.
Kunamabala asemhlabeni wonke, kodwa lawo ahloselwe ukusetshenziswa ngaphakathi awawona neze awokusetshenziswa kwangaphandle. Uma zisetshenziswa ngaphandle, umbala uzonyamalala ngemva konyaka.
Uma amafasitela ephathwa ngama-varnish asekelwe emanzini, ama-UV inhibitors atholakala kusisekelo, kodwa ikakhulukazi ezendlalelo zokugcina ngenxa yokuthi ayizivikelo zokuqala elangeni. Yingakho ungqimba lokugcina lwe-varnish lunombala “okhilimu”, onyamalala ngesikhathi sokumisa futhi lube obala, ukuze umbala ovela kungqimba lokuqala ubonakale ngawo.
Ukuma kwewindi kukuthinta kanjani ukuqina kwento enamathelayo?
Ukulahleka kwe-inhibitor kubonakala kakhulu kumafasitela ohlangothini lwendlu oluchayeke kakhulu elangeni. Emafasiteleni ohlangothini olusenyakatho, lapho ilanga lingafinyeleli khona, noma eminyango yangaphambili enezinsika lapho imisebe ingawi, lo mphumela ngeke uvele ngendlela efanayo.
Kufanele apendwe kabusha nini amafasitela okhuni?
Uma amafasitela ehlangothini oluseningizimu, lapho kunelanga eliningi khona, kufanele apendwe kabusha ngemva kweminyaka emingaki? Awukho umthetho owodwa. Kuya ohlangothini iwindi elikulo nokuthi ingakanani imisebe ye-UV efinyelela kulo.
Uma ivanishi ingeyekhwalithi enhle futhi kulandelwa inqubo, ngokuvamile abakhiqizi banikeza iwaranti yeminyaka emihlanu kuvanishi. Kukhona abakhiqizi abanikeza isiqinisekiso seminyaka eyishumi, kodwa ngesimo sokuthi ikhasimende lifaka ngesandla isendlalelo esisha se-varnish efasiteleni kanye noma kabili ngonyaka.
Kungani ukwakhiwa kwamafasitela nokufakwa kwevanisha kubalulekile?
Izinga lokulimala kwewindi phakathi neminyaka lincike kakhulu ekwakhiweni ngokwako. Kubalulekile ukuthi amafasitela atsheke ukuze amanzi angahlali kuwo.
Uma amajazi okugcina e-varnish engasetshenziswa kahle noma ama-varnishes ane-UV inhibitor encane, ama-inhibitors azoguga ngokushesha ngaphansi kwethonya le-UV futhi kuzovela imifantu ku-varnish. Uma ukubumba okuphansi kwewindi kungenayo i-engeli eyanele, futhi wonke amanzi avuzayo phansi iwindi edlula phezu kwalo, upende uzowa kuleyo ndawo kuqala.
Isifinyezo
Ilanga lisebenza ku-varnish, ama-UV inhibitors aguga futhi i-varnish iyaqhekeka lapho ubuso buba buthaka. Uma ukwakhiwa kwefasitela kubi, amanzi agcinwa, angena emifantwini futhi izinkuni zishiywe cishe zingavikelekile.
Yingakho kubaluleke kakhulu ukuthi izendlalelo zokugcina zisetshenziswe izikhathi eziningana nokuthi ungqimba ngalunye lube lukhulu ngangokunokwenzeka. Lokhu kungenziwa kuphela ngama-varnishers aqeqeshwe kahle, ngoba i-varnish isesimweni se-liquid futhi ivuza noma i-slide ebusweni. Ngakho-ke i-varnish ifaka i-varnish emngceleni omncane phakathi koqweqwe olwanele nokushelela.
Zonke izinyathelo kufanele zihlonishwe, kodwa naphezu kwawo wonke amaphuzu kule nqubo, isici somuntu sihlala, esinganqumi kuphela ukuthi sigcwalisekile, kodwa nokuthi sigcwaliseka kahle kangakanani.
Uma ukuvikela unomphela kwendawo yokuhlanganisa yangaphandle kubalulekile kuwena, bheka amafasitela okhuni, iminyango yangaphambili yethu noma uxhumane nathi ukuze uthole isicaphuna neseluleko.
