Ukupeyinta amashiti entsimbi ngokufanelekileyo, ukulungiswa okufanelekileyo komphezulu kunye nemathiriyeli ekhethekileyo ibalulekile ngenxa yentsimbi engaxutywanga nengenazibonda, umphezulu okwaziyo ukudleka. Apha ngezantsi sisikhokelo esibanzi esekwe kwiinkqubo zeshishini:

1. Ukulungiswa komphezulu (Elona nyathelo libaluleke kakhulu)

• Ukunciphisa: Susa i-oyile, ukungcola, okanye iintsalela usebenzisa izinyibilikisi ezifana ne-acetone, i-isopropyl alcohol, okanye izicoci zesinyithi ezikhethekileyo. Qinisekisa ukuba umphezulu womile ngokupheleleyo emva koko.

• I-Abrasion: Hlaziya umphezulu wepeyinti ukuphucula ukunamathela kwepeyinti:

  • I-Mechanically abrade nge-120-240 grit sandpaper okanye sebenzisa i-sandblasting (isebenza ngokukodwa kwiindawo ezinkulu). Oku kudala "iprofayile" ukuze ipeyinti ibambe.

  • Ukugqiba okukhazimlisiweyo/kwesipili (umzekelo, 8K/12K), i-abrasion enobundlobongela ibalulekile

• Unyango lomhlwa: Ukuba kukho umhlwa (umzekelo, kwiiwelds okanye kwimikrwelo), susa iiflakes ezishukumayo ngebrashi yocingo kwaye usebenzise i-oyile echasene nomhlwa okanye i-phosphoric acid-based converters ukuzinzisa umphezulu.
• Intsalela yokucoca: Sula uthuli okanye amasuntswana abrasive ngelaphu letakhi okanye iragi emanzi.

2. Ukuqalisa

• Sebenzisa i-primer yentsimbi ethile:

  • Iiprimers ezizibambayo: Ibhondi yekhemikhali kwintsimbi engatyiwayo (umzekelo, i-epoxy okanye i-zinc-rich formulations).

  • Izixhobo zokunqanda umhlwa: Kwiindawo ezingaphandle/ezirhabaxa, qwalasela iiprimers ezineempawu ezinqanda umhlwa (umzekelo, iiprimers ezisekelwe kwi-linseed oyile ukwenzela ukomeleza ukuxhathisa kwamanzi).

• Faka isicelo kwiidyasi ezibhityileyo. Vumela ukomiswa ngokupheleleyo ngokwemiyalelo yomenzi (ngokuqhelekileyo 1-24 iiyure).

3. Ipeyinti Isicelo

• Iintlobo zepeyinti:

  • Iipeyinti zokutshiza (i-Aerosol): Ilungele ukugquma ngokulinganayo kumashiti asicaba. Sebenzisa i-acrylic, i-polyurethane, okanye i-enamel formulations ebhalwe ngesinyithi. Vuthulula iinkonkxa ngamandla kangangemizuzu emi-2+ ngaphambi kokusetyenziswa.

  • Ibrashi/iRola: Sebenzisa iipeyinti zentsimbi ezincamathelayo eziphezulu (umzekelo, ialkyd okanye i-epoxy). Ziphephe iidyasi ezishinyeneyo ukuthintela ukuthontsiza.

  • IiNdlela eziKhethekileyo:

    • Ipeyinti yeoli ye-Linseed: Igqwesileyo ukuqina kwangaphandle; ifuna i-undercoat yeoli echasene nomhlwa.

    • Ukugquma kwePowder: Ukugqitywa kwe-oven enyangelwe ngubuchwephesha ukwenzela ukuqina okuphezulu (kungekhona i-DIY-friendly).

• Ubuchwephesha:

  • Bamba iinkonkxa zokutshiza umgama oyi-20-30 cm.

  • Faka iidyasi ezi-2-3 ezibhityileyo, ulinde imizuzu emi-5-10 phakathi kweedyasi ukuze ugweme ukugoba.

  • Gcina ukudibana okungaguquguqukiyo (50%) ukulungiselela ukugubungela okufanayo.

4. Ukunyanga nokutywinwa

Vumela ipeyinti ukuba inyange ngokupheleleyo (ngokuqhelekileyo kwiiyure ezingama-24-72) phambi kokuphathwa.

Kwiindawo ezinxibileyo eziphezulu, sebenzisa i-polyurethane topcoat ecacileyo ukunyusa ukukrazula / ukuxhathisa kwe-UV.

Emva konyango: Susa i-overspray ngokukhawuleza kunye nezinyibilikisi ezifana ne-mineral spirits.

5. Ukusombulula iingxaki kunye noLondolozo

• Imiba eqhelekileyo:

  • Ukuxobulwa/Ukuqweqwedisa: Okubangelwa kukungacoceki ngokwaneleyo okanye ukutsiba iprimer.

  • I-Fisheyes: Iziphumo ezivela kwizinto ezingcolisa umphezulu; ukucoca kwakhona kunye nesanti iindawo ezichaphazelekayo.

  • Ukutshintsha kobushushu: Ukuba i-welding iyenzeka emva kokupeyinta, sebenzisa i-copper / aluminium ukushisa kweesinki ukunciphisa umonakalo; phucula amanqaku ngentlama yokukhetha.

• Ugcino: Faka kwakhona i-oyile enqanda umhlwa okanye ipeyinti yokucofa rhoqo emva kweminyaka emi-5 ukuya kweli-10 kumphezulu wangaphandle 3.

Iindlela ezizezinye zokupeyinta

I-Electroplating: Idiphozithi yechromium, i-zinc, okanye i-nickel yokuqina / ukumelana nokubola.

Ukutshiza okuThermal: Iingubo ze-HVOF / zeplasma zokuxhatshazwa ngokugqithiseleyo (ukusetyenziswa kwamashishini).

Ukugqitywa kokuhlobisa: Amaphepha entsimbi angenambala ngaphambili (umzekelo, isibuko segolide, ibrashi) asusa iimfuno zokupeyinta.

Amanqaku okhuseleko

Sebenza kwindawo engena umoya; sebenzisa izixhobo zokuphefumla kwiipeyinti zokutshiza.

Gcina iipeyinti ezingaphantsi kwe-45 ° C kwaye ulahle amalaphu ngokufanelekileyo (izinto ezifakwe kwi-linseed-oyile ziyakwazi ukuzitshisa).

Ingcebiso yePro: Kwizicelo ezibalulekileyo (umzekelo, iimoto okanye ulwakhiwo), vavanya inkqubo yakho yokulungiselela/ipeyinti kwisiqwenga esilahliweyo kuqala. Ukungaphumeleli kokuncamathela kwintsimbi engatyiwa phantse rhoqo ngenxa yokungonelanga kokulungiswa komhlaba!
