Intsimbi ekhandiweyo isetyenziswa ngokubanzi kulwakhiwo, ucingo, iimoto, kunye nezicelo ezahlukeneyo zemizi-mveliso ngenxa yokumelana nokubola kunye nokuqina okuhlala ixesha elide. Inkqubo ye-galvanization igubungela isinyithi kunye noluhlu lwezinc, olukhusela kwi-rust kunye nezinye iindlela zokunciphisa. Nangona kunjalo, ngelixa i-galvanized coating isebenza kakhulu ekuthinteleni ukubola, inokwenza ukupeyinta intsimbi kube nzima ngakumbi.
Kwesi sikhokelo sibanzi, siya kukuhamba ngenyathelo ngenyathelo lokupeyinta intsimbi ye-galvanized , ukunika iingcebiso kwizinto eziyimfuneko, ukulungiswa, kunye nobuchule bokuqinisekisa ukuba ipeyinti ibambelela ngokufanelekileyo kwaye ihlala iminyaka. Nokuba usebenza kwiprojekthi ye-DIY okanye usetyenziso lobuchwephesha, ukwazi ukupeyinta intsimbi ekhandisiweyo kubalulekile ukugcina isibheno sayo sobuhle kunye nokuqina.
Kutheni Sipeyinta intsimbi yeGalvanized?
Ngaphambi kokuntywila kwinkqubo yokupeyinta steel galvanized , kubalulekile ukuqonda ukuba kutheni unokufuna ukuyipeyinta kwindawo yokuqala. Izizathu eziphambili zokupeyinta intsimbi yentsimbi ziquka:
Ukuphuculwa kobuhle : Intsimbi ekhandiweyo inenkangeleko eyodwa, emenyezelayo kangangokuba abanye abantu basenokungayifumani. Ukupeyinta intsimbi kukuvumela ukuba uyinike ukugqiba ngokwezifiso okanye ubuchwephesha obuhambelana nezinto ozikhethayo zoyilo.
Ukomelezwa kokuqina : Ngelixa isinyithi esinezibilini simelana ne-rust kunye ne-corrosion, ukupeyinta kuyongeza ukhuseleko olongezelelweyo. Oku kunokunceda ukwandisa ixesha lokuphila kwayo, ngakumbi kwiimeko ezinzima apho inokuthi ibe sesichengeni kwiikhemikhali, imitha ye-UV, okanye iimeko zemozulu ezimbi.
Ukuphawulwa kunye nokuchongwa : Kumashishini okanye abavelisi, ukupeyinta intsimbi ekhandiweyo inokuba yindlela ebalaseleyo yokongeza iilogo, imibala yebhrendi, okanye ezinye iimpawu kumphezulu wentsimbi.
Ukuthintelwa kokuBulala : Ngokuhamba kwexesha, ukukhanya kwelanga kunye nezixhobo kunokubangela ukuba intsimbi yegalvanized iphele. Ukufaka ipeyinti kunokunceda ukukhusela umphezulu wokuthotywa kwe-UV.
Imingeni yokupeyinta intsimbi ekhandisiweyo
Ukupeyinta intsimbi ekhandisiweyo akufani nokupeyinta ezinye iintsimbi njengentsimbi okanye ialuminiyam. Imingeni ephambili eyayanyaniswa nokupeyinta intsimbi yegalvanized ibandakanya:
I-Zinc Coating : Isigqubuthelo se-zinc se-galvanized yenzelwe ukukhusela intsimbi kwi-corrosion, kodwa inokuthintela ipeyinti ukuba ibambelele ngokufanelekileyo kumphezulu. I-Zinc igudile, nto leyo eyenza kube nzima ukuba ipeyinti idale iqhina eliqinileyo.
I-oyile kunye ne-Grease : Ngethuba lenkqubo ye-galvanizing, isinyithi sihlala sigqunywa kwinqanaba elincinci leoli okanye igrisi, elinokuthi lichaphazele ukunamathela kwepeyinti. Ezi zingcolisi kufuneka zisuswe ngaphambi kokufaka ipeyinti.
Ukubunjwa kweMichiza : Ukubunjwa kweekhemikhali zengubo ye-galvanized ngamanye amaxesha kunokuphazamisa iintlobo ezithile zepeyinti, ezikhokelela kwiziphumo ezimbi okanye ukugqoka kwangaphambili.
Nangona le mingeni, ngokulungiswa okufanelekileyo kunye nobuchule, unokufezekisa ukugqiba umgangatho ophezulu xa upeyinta isinyithi se-galvanized.
Indlela yokuLungisa intsimbi yeGalvanized for Painting
Ukulungiswa okufanelekileyo kungundoqo ekuqinisekiseni ukuba ipeyinti ibambelela kakuhle kwaye inika ukhuseleko oluhlala ixesha elide. Landela la manyathelo abalulekileyo ekulungiseleleni intsimbi ekhandisiweyo phambi kokupeyinta:
1. Coca uMphezulu
Inyathelo lokuqala lokupeyinta intsimbi ekhandisiweyo kukucoca ngokucokisekileyo umphezulu ukuze ususe nabuphi na ubumdaka, uthuli, ioyile okanye igrisi. Ukucoca kuqinisekisa ukuba ipeyinti ibambelela ngokufanelekileyo kwaye akukho zingcoliso ezinokubangela ukuba ipeyinti ixobuke okanye i-chip. Nantsi indlela yokucoca intsimbi:
Hlamba ngamanzi kunye ne-Detergent : Xuba amanzi kunye nesicoci esithambileyo kwi-emele kwaye usebenzise ilaphu okanye isipontshi ukuhlamba intsimbi. Khuhla nabuphi na ubumdaka okanye inkunkuma engaphezulu.
Hlanza kwaye Wome : Emva kokucoca, hlambulula intsimbi ngamanzi ukuze ususe nayiphi na intsalela ye-detergent. Yomisa umphezulu ngelaphu elicocekileyo, elomileyo.
Sebenzisa i-Degreaser : Kwimigangatho eneoli ebalulekileyo okanye i-grease buildup, ungasebenzisa i-degreaser ukuqinisekisa ukuba intsimbi icoceke ngokupheleleyo.
2. Ukukrola iNsimbi
Emva kokucoca, inyathelo elilandelayo kukufaka umphezulu wensimbi. I-Etching yinkqubo yokurhaxa kancinci indawo egudileyo ye-zinc coating ukuphucula ukuncamatheliswa kwepeyinti. Unokusebenzisa isisombululo se-etching esilungiselelwe ngokukodwa imiphezulu yegalvanized. Isisombululo siya kumisa umphezulu wekhemikhali, ukubonelela ngebhondi engcono phakathi kwepeyinti kunye nentsimbi.
Faka isicelo se-Etching Solution : Faka isisombululo se-etching kumphezulu wensimbi ye-galvanized usebenzisa i-brush okanye isiponji. Landela imiyalelo yomenzi malunga nesicelo kunye nokhuseleko.
Hlanza kwaye Wome : Emva kokuba umphezulu ugqityiwe, susela intsimbi ngokucokisekileyo ngamanzi kwaye uvumele ukuba yome ngokupheleleyo ngaphambi kokuba uqhubele phambili kwipeyinti.
3. Ukusantiya uMphezulu
Nje ukuba umphezulu ucociwe kwaye uhlonyelwe, luluvo olulungileyo ukwenza isanti kancinci kwintsimbi eyenziwe ngamagalvanized ukuze uphucule ngakumbi ukunamathela kwepeyinti. Ukusantiya kunokunceda ukususa naziphi na ii-oyile eziseleyo okanye izinto ezingcolisayo ngelixa usenza indawo erhabaxa ukuze ipeyinti idibane nayo.
Sebenzisa i-sandpaper ye-fine-grit (malunga ne-220-grit) ukwenza isanti kancinci phezulu. Gwema isanti enobundlobongela enokuthi yonakalise i-zinc coating okanye idale iindawo ezingalinganiyo.
Emva kokuba umphezulu ufakwe isanti, wosule ngelaphu elicocekileyo, elomileyo ukuze ususe naluphi na uthuli okanye inkunkuma.
4. Faka isicelo se-Metal Primer
Ukusebenzisa i-primer kubalulekile ekufezekiseni ukugqiba okugudileyo, okuhlala ixesha elide kwintsimbi ye-galvanized. I-primer iya kudala indawo ezinzileyo ukuze ipeyinti ibambelele kwaye incede ukukhusela i-rust and corrosion.
Khetha i-Primer eLungileyo : Sebenzisa i-primer eyenzelwe ngokukodwa isinyithi se-galvanized. Ezi ziqalo ziqulethe abagqugquzeli abakhethekileyo bokubambelela abancedisa ibhondi yepeyinti kwi-coating zinc.
Faka isicelo ngokulinganayo : Faka i-primer ngokulinganayo kumphezulu usebenzisa ibrashi yokupeyinta, i-roller, okanye i-spray can. Qinisekisa ukugubungela zonke iindawo ezivulekileyo zentsimbi.
Vumela ukuba Yome : Vumela i-primer yome ngokwemiyalelo yomenzi. Oku kuthatha iiyure ezimbalwa, kodwa kufuneka uhlale ujonga ileyibhile yemveliso ngamaxesha athile okoma.
Upeyintwa Njani Intsimbi eGalvanized
Ngoku ukuba intsimbi yakho ye-galvanized prepped kunye ne-primed, lixesha lokusebenzisa ipeyinti. Nali inyathelo ngenyathelo isikhokelo sendlela yokwenza:
1. Khetha iPeyinti eLungileyo
Ukukhetha uhlobo olululo lwepeyinti lubalulekile kwimpumelelo. Ngentsimbi ye-galvanized, udinga ipeyinti eya kudibanisa kakuhle nomphezulu kwaye inike ukhuseleko oluhlala ixesha elide. Ipeyinti ye-acrylic latex okanye ipeyinti esekwe kwi-oyile eyenzelwe umphezulu wesinyithi isebenza kakuhle kwintsimbi ekhandisiweyo.
Ipeyinti ye-Acrylic : Iipende ze-acrylic latex zisekelwe kumanzi kwaye zibonelela ngokugqwesa ukubambelela kunye nokuqina. Ziphinde zome ngokukhawuleza, zibenze ukhetho oludumileyo lokupeyinta intsimbi.
Ipeyinti esekelwe kwi-oyile : Ipeyinti esekelwe kwi-oyile yenye inketho enkulu kwintsimbi ye-galvanized. Banikezela ngokugqitywa okunzima, okuhlala ixesha elide kwaye bagqwesileyo kwiindawo ezivezwe ngokuguga kunye nokukrazula.
2. Faka ipeyinti
Sebenzisa ibrashi, irola, okanye umpu wokutshiza ukuze usebenzise ipeyinti. Ngezona ziphumo zibalaseleyo, sebenzisa iidyasi ezimbini zepeyinti ukuze uqinisekise ukugqunywa kunye nokhuseleko oluhlala ixesha elide. Landela ezi ngcebiso malunga nesicelo esicocekileyo nesigudileyo:
Sebenzisa i-Smooth Strokes : Xa usebenzisa ibrashi yepeyinti okanye i-roller, sebenzisa i-smooth, nkqu imivumbo ukuze ugweme ukushiya i-streaks okanye iileya ezingalinganiyo.
Ukutshiza Ukupeyinta : Ukuba usebenzisa umpu wokutshiza, bamba isitshizi kangange-intshi ezi-6–8 ukusuka kumphezulu kwaye usebenzise ukukhanya, kwaneedyasi. Qinisekisa ukuba ugubungela zonke iindawo zentsimbi.
Vumela Ixesha Lokomisa : Emva kokuba isambatho sokuqala sepeyinti sisetyenzisiwe, masiyome ngokwemiyalelo yomenzi ngaphambi kokuba usebenzise isambatho sesibini.
3. Faka iTopcoat ekhuselayo
Ukongezelela ukuqina kunye nokukhusela, cinga ukusebenzisa i-topcoat ecacileyo phezu kwepeyinti. I-topcoat ecacileyo inceda ukukhusela indawo epeyintiweyo kwimikrwelo, ukufuma, kunye nemitha ye-UV. Kwakhona kwandisa ixesha elide lomsebenzi wepeyinti.
