Ukuze upende amashidi ensimbi engagqwali ngempumelelo, ukulungiswa kahle kwendawo nezinto ezisetshenziswayo ezikhethekile kubalulekile ngenxa yendawo yensimbi engagqwali engenazimbobo, nekwazi ukumelana nokugqwala. Ngezansi umhlahlandlela ophelele osuselwe kuzinqubo zemboni:

1. Ukulungiswa kwendawo (Isinyathelo Esibaluleke Kakhulu)

• Ukwehlisa amafutha: Susa amafutha, ukungcola, noma izinsalela usebenzisa izincibilikisi ezifana ne-acetone, i-isopropyl alcohol, noma izihlanzi zensimbi ezikhethekile. Qinisekisa ukuthi indawo yomile ngokuphelele ngemva kwalokho.

• I-Abrasion: Hlikihla ubuso ukuze uthuthukise ukunamathela kopende:

  • Abrade ngomshini nge-sandpaper yegrit engu-120–240 noma sebenzisa i-sandblasting (isebenza kahle kakhulu ezindaweni ezinkulu). Lokhu kudala "iphrofayela" ukuze upende ubambe.

  • Ekuqedweni okupholishiwe/kwesibuko (isb, 8K/12K), ukuhuzuka okunamandla kubalulekile

• Ukwelapha Ukugqwala: Uma kukhona ukugqwala (isb., kumashisela noma emiklwebheni), susa ama-flakes axegayo ngebhulashi locingo bese usebenzisa uwoyela ovimbela ukugqwala noma iziguquli ezisekelwe ku-phosphoric acid ukuze uzinzise indawo engaphezulu.
• Izinsalela Zokuhlanza: Sula uthuli noma izinhlayiya ezilumayo ngendwangu yokudonsa noma iragi elimanzi.

2. Ukuqamba

• Sebenzisa i-primer eqondene nensimbi:

  • Iziqalo ezizibambayo: Zibophezela ngamakhemikhali ensimbi engagqwali (isb, i-epoxy noma i-zinc-rich rich formulations).

  • Iziqalo ezinqanda ukugqwala: Ezindaweni zangaphandle/ezinokhahlo, cabangela ama-primer anezakhiwo ezivimbela ukugqwala (isb., ama-primers asekelwe ku-olinseed asekelwe kuwoyela ukuze kuthuthukiswe ukumelana kwamanzi).

• Faka amajazi amancane, ngisho namajazi. Vumela ukomiswa okugcwele ngokwemiyalelo yomkhiqizi (imvamisa amahora angu-1-24).

3. Isicelo sikapende

• Izinhlobo zikapende:

  • I-Spray Paints (Aerosol): Ilungele ukumbozwa ngisho nakumashidi ayisicaba. Sebenzisa ukwakheka kwe-acrylic, i-polyurethane, noma koqweqwe lwawo olubhalwe ngensimbi. Nyakazisa amathini ngamandla imizuzu engu-2+ ngaphambi kokuwasebenzisa.

  • Ibhulashi/Irola: Sebenzisa opende bensimbi abanamathela kakhulu (isb, i-alkyd noma i-epoxy). Gwema amajazi awugqinsi ukuze uvimbele ukuconsa.

  • Izinketho Ezikhethekile:

    • Upende kawoyela we-linseed: Kuhle kakhulu ukuqina kwangaphandle; idinga i-undercoat yamafutha e-anti-rust.

    • I-Powder coating: Isiphetho se-ovini esenziwe ngochwepheshe ukuze sihlale siqinile (hhayi i-DIY-friendly).

• Icebo:

  • Bamba amathini okufutha ngo-20-30 cm kude.

  • Gcoba amajazi amancane angu-2-3, ulinde imizuzu engu-5-10 phakathi kwamajazi ukuze ugweme ukugoqa.

  • Gcina ukugqagqana okungaguquki (50%) ukuze kuhlanganiswe okufanayo.

4. Ukwelapha & Ukubekwa uphawu

Vumela upende ukuthi ululaphe ngokugcwele (imvamisa amahora angama-24-72) ngaphambi kokuphatha.

Ezindaweni ezigqokwa kakhulu, faka ijazi elicacile le-polyurethane ukuze uthuthukise ukumelana nokuklwebheka/ku-UV.

Ngemuva kokwelashwa: Susa i-overspray ngokushesha ngezincibilikisi ezifana ne-mineral spirits.

5. Ukuxazulula izinkinga nokunakekela

• Izinkinga Ezivamile:

  • Ukucwecwa/Ukukhipha amabhamuza: Kudalwa ukungahlanzeki ngokwanele noma ukweqa i-primer.

  • Ama-Fisheyes: Umphumela wokungcola okungaphezulu; hlanza kabusha futhi izindawo ezithintekile kwesihlabathi.

  • Ukushintshashintsha kokushisa: Uma ukushisela kwenzeka ngemva kokupenda, sebenzisa amasinki okushisa ethusi/aluminium ukuze unciphise umonakalo; pholisha amamaki nge-pickle paste.

• Ukunakekela: Faka kabusha uwoyela ovimbela ukugqwala noma upende othintwayo njalo ngemva kweminyaka engu-5–10 endaweni yangaphandle 3.

Ezinye izindlela Zokudweba

I-Electroplating: Idiphozithi i-chromium, i-zinc, noma i-nickel yokuqina/ukumelana nokugqwala.

I-Thermal Spraying: I-HVOF/plasma coatings yokumelana nokugqoka ngokweqile (ukusetshenziswa kwezimboni).

Ukuqedwa Kokuhlobisa: Amashidi ensimbi engenambala anombala wangaphambili (isb., isibuko segolide, esibhulashiwe) asusa izidingo zokudweba.

Amanothi Okuphepha

Sebenza endaweni engenawo umoya; sebenzisa ama-respirators ukuze upende amapende.

Gcina opende ngaphansi kuka-45°C futhi ulahle amanikiniki ngendlela efanele (izinto ezifakwe uwoyela we-linseed zingazishisa ngokwazo).

Ithiphu Yochwepheshe: Kuzinhlelo zokusebenza ezibucayi (isb., ezezimoto noma ezokwakha), hlola inqubo yakho yokulungiselela/yokupenda esicezwini esincane esilahliwe kuqala. Ukwehluleka ukunamathela ensimbi engagqwali cishe njalo kungenxa yokunganele kwendawo yokulungiselela!
