Ukuqinisekisa ukuqina kwesikhathi eside, ukumelana nokugqwala, kanye nokusebenza kwekhwalithi ephezulu kwezakhiwo zensimbi, ukulungiswa kwendawo okuchwepheshile kanye nezinqubo zokumboza zenziwa ngokuqinile ngesikhathi sokwenziwa.

Ngaphambi kokumbozwa, izingxenye zensimbi ziphathwa ngomshini odubulayo ozenzakalelayo ukuze kususwe ukugqwala, isikali sokugaya, amabala kawoyela, nokunye ukungcola. Ukudubula kusebenzisa umoya ocindezelwe ukusheshisa amashothi ensimbi ngesivinini esiphezulu endaweni yensimbi. Ngomthelela nokungqubuzana, ukugqwala, isikali se-oxide, nokungcola kususwa ngokuphelele, kudala indawo ehlanzekile enobunzima obufanele ukuze kuthuthukiswe ukunamathela kokunamathela.

Ngemva kokudubula, indawo yensimbi izohlanzwa kahle ngesisetshenziswa se-vacuum noma ngomoya ocindezelwe ukuze kukhishwe uthuli nezinhlayiya zensimbi. Indawo ephathwayo kufanele iveze ukubukeka okumpunga kwensimbi okufanayo.

Ngemuva kokuhlolwa nokugunyazwa ngabasebenzi bokulawula ikhwalithi, ungqimba lokuqala lwe-primer coating kufanele lusetshenziswe phakathi kwamahora angu-4 ukuvimbela i-oxidation yesibili nokuqinisekisa ukusebenza kokumboza.

1. Izindlela Zokuhlanganisa Isakhiwo Sensimbi

1.1 I-Primer Structure Yesakhiwo Sensimbi

I-primer coating iyisendlalelo sokuqala sokuzivikela esisetshenziswa ngemva kokulungiswa kwendawo. Inhloso yayo eyinhloko ukuthuthukisa ukumelana nokugqwala kanye nokuthuthukisa amandla okubopha phakathi kwensimbi nezindwangu ezilandelayo.

Inqubo yokumboza i-Primer:

1. Ukulungiswa Kwepende

I-Anti-corrosion primer kufanele ixutshwe kahle ngaphambi kokufaka. I-viscosity, ukungaguquguquki, kanye ne-dilution ratio kufanele ilawulwe ngokuqinile ukuze kuqinisekiswe umbala ofanayo, ukusebenza okuzinzile, nokusebenza okushelelayo.

2. Isicelo sokuqala sokuqala

Phakathi nenqubo yokuqala yokumboza i-primer, isiqondiso sokufafaza kufanele sihlale sivumelana. Izindawo ezigqagqene kufanele zibe bushelelezi futhi zifane ukuze ugweme ukushuba okungalingani.

3. Ukulawula Isifutho

Lapho befafaza i-primer, o-opharetha kufanele balandele isimiso sokunyakaza okuqhubekayo kanye nebanga elifushane lokufafaza ukuvimbela ukunqwabelana kopende ngokweqile, ukuwohloka, noma ukunamathela okungalingani.

4. Isendlalelo sokuqala sesibili

Ngemuva kokuthi isendlalelo sokuqala se-primer sesomile ngokuphelele, isembozo sesibili sizosetshenziswa. Isiqondiso sokufafaza kufanele sibe yi-perpendicular kuya kwesendlalelo sangaphambilini ukuze kuzuzwe ukushuba kwengubo efanayo nokuvikelwa okungcono.

5. Ukuhlonza Ingxenye

Ngemva kokuqedwa kokuhlanganisa, izingxenye zensimbi kufanele zimakwe ngokwezinombolo zokukhomba zangempela. Ezingxenyeni ezibalulekile, ulwazi olwengeziwe njengesisindo, indawo ye-gravity position, namamaki okufaka kufanele kukhonjiswe.

1.2 Isakhiwo Sensimbi Umdwebo we-Topcoat

Ijazi eliphezulu linikeza ukuvikeleka okwengeziwe ezimweni zezulu, ukugqwala, nomthelela wemvelo ngenkathi kuthuthukiswa ukubukeka kwezakhiwo zensimbi.

Izidingo zokufaka isicelo se-Topcoat:

1. Ukuhambisana Kwezingubo

I-topcoat material kufanele ihambisane nezidingo zokuklama. Ukuhambisana phakathi kwe-primer ne-topcoat kufanele kuqinisekiswe ukuze kugwenywe ukwehluleka ukunamathela okubangelwa ukusabela kwamakhemikhali phakathi kwezinto ezahlukene.

2. Ukuhlanza Ubuso Ngaphambi Kokupenda

Ngezakhiwo zensimbi ezidinga ukufakwa kwe-topcoat esizeni, indawo engaphezulu kufanele ihlanzwe ngemva kokufakwa. Uthuli, amabala kawoyela, izinsalela zokushisela, nokunye ukungcola kufanele kususwe ngaphambi kokupenda.

3. Ukulungiselela Ijazi eliphezulu

Umbala wejazi eliphezulu kufanele uhambisane nokucaciswa kokuklama. Ngaphambi kokusetshenziswa, upende kufanele uhlanganiswe ngokugcwele ukuze uqinisekise umbala ofanayo kanye ne-viscosity ezinzile. Ukulungiswa okufanele kwe-thinner kufanele kwenziwe ukuvimbela ukuwohloka, izimpawu zokuxubha, noma izindawo ezingalingani.

4. Indlela Yokudweba

Ngesikhathi sokufaka isicelo, i-topcoat kufanele ishukunyiswe ngokuqhubekayo. Isiqondiso sokudweba kanye nendlela yokufafaza kufanele ilandele izindinganiso ezifanayo nenqubo yokugqoka i-primer.

2. Izinyathelo zokuqapha ze-Steel Structure Coating

1. Ukuhlolwa Kwekhwalithi Ngaphambi Kokupenda

Ukufakwa kwesakhiwo sensimbi kufanele kwenziwe kuphela ngemuva kokuhlolwa kwekhwalithi yokwenziwa nokuvunywa. Zonke izingxenye kufanele zihlangabezane nezindinganiso zokukhiqiza ezidingekayo ngaphambi kokwelashwa okungaphezulu nokupenda.

2. Steel Surface Ukulungiselela

Ngaphambi kokumbozwa, izindawo zensimbi kufanele zilashwe ngokudubula ukuze kususwe ukugqwala, uwoyela, uthuli nokunye ukungcola.

Ibanga lokulungiswa kwendawo lizohlangabezana nezidingo ze- ISO 8501-1 / Sa 2.0 standard , liqinisekisa ukuhlanzeka okufanele kwendawo kanye nokunamathela kokunamathela.

3. I-Primer futhi Qeda Izidingo Zokuhlanganisa

Ngemuva kokulungiswa kwendawo, izingxenye zensimbi kufanele zithole i-primer coating yokuqala ngokushesha. Ngemuva kokwelashwa, izingqimba ezimbili zejazi eliphezulu zizofakwa ngaphandle uma kudingeka ukunamathela okungashi.

Izindawo ezilandelayo akufanele zipendwe:

• Izindawo zokuxhuma zamabhawodi eziqine kakhulu

• Izingxenye zensimbi ezishumekiwe ngaphakathi kwezisekelo zikakhonkolo

• Izindawo ezingaphakathi kuka-50mm zokungena okugcwele okuhlangene okushisela ezidinga ukushiselwa esizeni

4. Izidingo Zokunamathela Okungenamlilo

Kumalungu ensimbi adinga ukuvikelwa komlilo, ukugqoka okukhethiwe komlilo kufanele kuhambisane nezindinganiso ezisebenzayo zikazwelonke nezamazwe ngamazwe.

Ukunamathela okungangeni umlilo ngokuvamile kuzosetshenziswa ngemva kokufakwa kwesakhiwo sensimbi. Ukuhlola ukuhambisana phakathi kokumboza okungashi kanye ne-primer kufanele kuqedwe ngaphambi kokufaka isicelo.

3. Ukuhlolwa kwe-Steel Structure Coating kanye Nokwamukelwa

Ukuhlolwa kwekhwalithi okuqinile kwenziwa ngemuva kokumbozwa ukuze kuqinisekiswe ukuqina kwe-coat, ukubukeka, nokusebenza kokuvikela.

3.1 Ukuhlolwa kokubukeka

Ngemuva kokudweba kwesakhiwo sensimbi, indawo yokugqoka kufanele ihlangabezane nezidingo ezilandelayo:

• Umbala ofanayo nokubukeka okungaguquki

• Indawo ebushelelezi futhi ekhanyayo

• Ayikho imibimbi, imifantu, amabhamuza, iyaxebuka, noma izigaxa zopende

• Awekho amaphutha enamathela asobala

---

3.2 Ukuvikelwa Ngesikhathi Nangemuva Kokupenda

Ngesikhathi nangemva kokusebenza kokumboza, izingxenye zensimbi ezipendiwe kufanele zivikelwe ngendlela efanele:

• Ukungcoliswa kothuli

• Ukuchayeka komswakama

• Ukulimala komshini

• Okunye ukungcola kwangaphandle

Ukugcinwa okufanele kanye nezinyathelo zokuphatha kufanele zithathwe ngaphambi kokuthutha nokufakwa.

---

3.3 Ukukala Ukuqina Kokunamathela

Ugqinsi lwefilimu yokunameka kufanele luhlolwe kusetshenziswa igeji yokujiya yobuchwepheshe bedijithali.

Ngesikhathi sokuhlolwa:

• Kuzokhethwa amaphuzu amaningi okulinganisa engxenyeni ngayinye yensimbi.

• Amanani okuqina azorekhodwa futhi ahlaziywe.

• Isilinganiso esimaphakathi sokujiya sizohlangabezana nezidingo zokuklama iphrojekthi kanye namazinga asebenzayo.
