Isivikelo Sengqalasizinda Yomhlaba Wonke: Upende We-Topcoat Osekelwe Emanzini Ongagqwali I-Fluorocarbon

*Ukwakheka Komkhiqizo:

Upende we-fluorocarbon oqhutshwa ngamanzi uwupende osebenza kahle kakhulu, onobungani nemvelo osebenzisa i-resin ye-fluorocarbon eqhutshwa ngamanzi njengento eyinhloko eyakha ifilimu. Uthola ukuqina okuhle kakhulu, ukumelana nesimo sezulu, kanye nokumelana nokugqwala kopende we-fluorocarbon wendabuko osekelwe ku-solvent, kuyilapho ukusebenzisa amanzi njengesihlanzi kunciphisa kakhulu okuqukethwe yi-VOC (i-volatile organic compound), kuhlangabezana nezidingo zokuvikelwa kwemvelo eziluhlaza zanamuhla kanye nokukhiqiza okuphephile. Ukusetshenziswa ngempumelelo kobuchwepheshe obuqhutshwa ngamanzi ezihlangwini ze-fluorocarbon, okubizwa ngokuthi “inkosi yezihlangwini,” kumelela isiqongo sobuchwepheshe embonini yezihlangwini zodonga zokwakha nezangaphandle.

*Izici Zomkhiqizo:

● Ukuqina okuphezulu kwefilimu, ukumelana okuhle nokuguguleka, ukuqina okuhle kakhulu, kanye nokumelana nokushayisana.
● Ukumelana nesimo sezulu okuphezulu kanye nokugcinwa kombala/ukucwebezela: Kumelana ngempumelelo nokuwohloka kwe-UV, ukuguguleka kwemvula ene-asidi, kanye nokuguguleka komoya nesihlabathi; kumelana nokuguguleka kwe-choki kanye nokuguquka kombala.
● Ukumelana okuhle kakhulu nokugqwala kanye namakhemikhali: Ukumelana okuhle kakhulu namakhemikhali amaningi, izinyibilikisi, kanye nama-grease. Ukwembozwa okujiyile kuvimbela ngempumelelo ukungena komswakama, ama-ion e-chloride, kanye nama-sulfide, okunikeza ukuvikelwa okuhle kakhulu kokugqwala kwe-concrete kanye ne-metal substrates.
● Ukuzihlanza okuvelele kanye nokumelana namabala: Amandla aphansi omhlaba, okwenza kube nzima ukuthi ukungcola kunamathele.
● Inobungani nemvelo futhi iphephile: Isihlanzi esisekelwe emanzini, okuqukethwe kwe-VOC okuphansi kakhulu, akunabo ubuthi, akunaphunga, akushisi, futhi akuqhumi, okuqinisekisa ukusetshenziswa okuphephile.
●Ukusebenza kahle kanye nokunamathela: Ibonisa ukunamathela okuhle kakhulu ezintweni ezahlukahlukene, okuhlanganisa ukhonkolo ophathwe kahle, insimbi, amaphaneli e-aluminium ahlanganisiwe, kanye nokumbozwa okudala.

*Imininingwane Yobuchwepheshe:

*Ukusetshenziswa Komkhiqizo:

Isetshenziselwa ukuvimbela ukugqwala kwemishini yamakhemikhali, amapayipi kanye nezakhiwo zensimbi ezindaweni ezibucayi zezimboni. Ingapendwa ezakhiweni zensimbi, amaphrojekthi amabhuloho, izikhungo zasolwandle, amapulatifomu okubhoboza, amachweba namachweba, izakhiwo zensimbi, ubunjiniyela bomasipala, izivikelo zesivinini esikhulu, ukuvimbela ukugqwala ngokhonkolo, njll.

*Ukwelashwa Komphezulu:

Ukuqinisekisa ukunamathela kwefilimu kanye nokuvikelwa kokugqwala kwesikhathi eside, ubuso be-substrate kumele buhlanzwe kahle ku-oyili, ukugqwala, isikali, upende omdala, kanye nokungcola okuxekethile ngaphambi kokufaka. Izindinganiso zokulungiselela kufanele zihlangabezane nalokhu okulandelayo:

Zonke izindawo ezizogqokwa kufanele zihlanzeke, zome futhi zingangcoliswa. Ngaphambi kokupenda, zonke izindawo kufanele zihambisane ne-ISO_{8504: 2000}ukuhlolwa nokucubungula okujwayelekile.

Insimbi elinganisiwe iqhunyiswa ku-Sa_2.5ibanga, ubulukhuni bomphezulu bungu-30-75μm, noma bufakwe emanzini abandayo, buncishisiwe futhi abunamsebenzi;

Insimbi engena-okside iqhunyiswe eSa_2.5ibanga, noma elipholishiwe ukuya eSt₃ibanga elinesondo lokugaya elinomoya noma elenziwe ngogesi;

Izinsimbi ezimbozwe nge-primer ye-workshop umonakalo wefilimu yopende, ukugqwala kanye nokugqwala okumhlophe ku-primer ye-zinc powder kufanele kususwe ukugqwala kabili, ukugqwala okumhlophe kususwe bese kupholishwa ku-St.₃.

Ezinye izindawo Lo mkhiqizo usetshenziselwa ezinye izinto ezisetshenziswayo, sicela uxhumane nomnyango wethu wezobuchwepheshe.

*Isimo Sokwakha:

Izinga lokushisa le-substrate alikho ngaphansi kuka-5 ℃, futhi okungenani liphakeme ngo-3 ℃ kunezinga lokushisa le-air dew point kanti umswakama ohlobene ungaphansi kuka-85% (izinga lokushisa kanye nomswakama ohlobene kufanele kulinganiswe eduze kwe-substrate). Ukwakha akuvunyelwe ngokuphelele enkungwini, eqhweni kanye nesimo sezulu esinomoya.

*Izinyathelo Zokwakha:

Isinyathelo 1: Ukulungiswa Komphezulu We-Substrate (I-TheUkhiyeIsinyathelo)

Ikhwalithi yokulungiswa kwendawo inquma ngqo ukunamathela kanye nesikhathi sokuphila kwefilimu yopende.

Izindawo zensimbi kumele zisuswe amafutha futhi zingagqwali (ngokwezindinganiso ze-Sa2.5 noma ze-St3) ukuqinisekisa ukuthi izindawo zensimbi ezizopendwa kumele zihlanzeke kahle, zome ngokuphelele, futhi zingangcolisi njengamafutha, amafutha, uthuli, usawoti, isikali, kanye nopende omdala okhululekile. Akuvunyelwe umswakama noma ukuminyana okubonakalayo.

Indawo ephathwayo kufanele ihlangabezane nezindinganiso zokuhlanzeka nokwakheka kokwakheka, futhi upende kufanele usetshenziswe ngokushesha okukhulu ukuze kuvinjelwe ukugqwala noma ukungcola kwesibili.

Si-tep2: Sebenzisa i-Primer

Ngokusho kwesisekelo kanye nendawo ethile, ukhethe i-primer ehambisanayo (i-Epoxy Zinc-Rich Primer, i-Epoxy Zinc Phosphate Primer).

Isinyathelo sesi-3: Faka upende we-Fluorocarbon osekelwe emanzini

Thela kancane kancane ingxenye B (i-ejenti yokwelapha) engxenyeni A (upende we-fluorocarbon osekelwe emanzini), kahle ngokwesilinganiso esibekiwe (ngesisindo). Ngemva kokuxuba ngokuphelele, vumela ingxube ime imizuzu emi-5-10 ukuze ivuthwe. Bese ungqimba oluxubile lusetshenziswa zingakapheli amahora ama-4 (impilo yebhodwe). Bese uxubha/ugoqa noma ufutha, ukufutha okungenamoya kunikeza ukusebenza kahle okuphezulu futhi kukhiqiza ikhwalithi engcono kakhulu yefilimu yopende. Uma unemishini namasu ochwepheshe, kuzoba ngcono kakhulu. Ukusetshenziswa kopende okungokwethiyori kungu-0.2kg/m²/ijazi. (Ukusetshenziswa kwangempela kungahluka kuye ngokuthungwa kwendawo, ukugoba, indlela yokufaka kanye nobuchwepheshe bokusebenzisa.)

Qaphela:

*Uma kudingeka ukunciphisa, ncibilikisa ngamanzi ahlanzekile ngokwe-viscosity yokufaka kanye nendlela (ukuxubha, ukugoqa, noma ukufutha). Lungisa i-viscosity ukuze ivumelane nendlela ethile yokufaka.

* Isilinganiso sokuxuba esingu-5-20% ngesisindo. Ukunciphisa ngokweqile kuzothinta kabi ukwakheka kwefilimu, amandla okufihla, kanye nokuqina kwesikhathi eside.

* Ngaphambi kokufaka ingubo elandelayo, qiniseka ukuthi ingubo yangaphambilini ipholile ngokuphelele, ihlanzekile, yomile, futhi ayinazo zonke izinto ezingcolisayo.

* Gwema ukuxubha ngamandla ukuze uvimbele ukungena kwamabhamuza amaningi.

* Isikhawu Sokumboza Kabusha: Ezindaweni ezingonakalisi kancane: upende o-1 we-primer + upende o-2 we-midcoat + upende o-2 we-topcoat; ezindaweni ezingonakalisi kakhulu, khulisa ubukhulu be-coating.

*Indlela Yokwakha:

Ukufutha: Ukufutha ngaphandle komoya noma ukufutha ngomoya. Kunconywa ukufutha ngaphandle komoya ngomfutho ophezulu.
Ukuxubha/Ukugoqa: Ubukhulu befilimu eyomile echaziwe kumele bufinyelelwe.

*Uhlelo Lokumboza:

Sincoma ukusebenzisa uhlelo oluphelele “lokuvala i-primer + i-intermediate coat + i-water-based fluorocarbon topcoat” ukuze kutholakale imiphumela emihle kakhulu kanye nokusebenza kahle kwezindleko.

I-PrimerIzibonelo zifaka phakathi i-primer ecebile nge-zinc esekwe emanzini kanye ne-primer epoxy esekelwe emanzini. Umsebenzi wayo oyinhloko ukuhlinzeka ngokuvikelwa okuhle kakhulu kokulwa nokugqwala kanye nokunamathela.

Ijazi Eliphakathi:Ngokuvamile i-epoxy micaecous iron oxide coat esekelwe emanzini. Yandisa ukujiya kwesembozo esiphelele, isebenza njengesithiyo ngokumelene nomswakama kanye nezinto ezilimazayo, futhi ithuthukisa ukusebenza kokuvikela okuphelele.

Ijazi eliphezulu:I-topcoat ye-fluorocarbon inikeza umugqa wokugcina wokuzivikela ekugugulekeni nasekuguguleni, kanye nokubukeka okuhle okufiswayo.

*Izinyathelo zokuzivikela:

▶ Izinga lokushisa lokwakha lingu-5℃-35℃ (Ukulungiswa okuqondile kwenziwa ngokwezici zomkhiqizo, umswakama u-≤80% futhi kugwema imvula.

▶ Gcina umoya omuhle ukuze kube lula ukuhwamuka komswakama kanye nokupholisa ifilimu yopende.

▶ Vikela ekuqandeni ngesikhathi sokugcina.

▶ Imishini yokuzivikela kumele igqokwe ngesikhathi sokuqhumisa isihlabathi

▶ Inkungu, imvula, iqhwa, umoya kanye nemvula akuvunyelwe ngokuphelele ukwakha.

*Isitoreji kanye Nempilo Yeshelufu:

▅ Gcina endaweni yokugcina izinto epholile, eyomile, enomoya opholile emazingeni okushisa angu-5-35 ℃, gwema ukubanda nokukhanya kwelanga okuqondile;

▅ Isikhathi sokuphila siyizinyanga ezingu-12. Uma imikhiqizo idlula isikhathi sokugcina ingasetshenziswa ngemva kokudlula ukuhlolwa.

*Iphakheji:

Upende：20Kg/Ibhakede(18Liter/Ibhakede); I-Hardener: 4Kg/Ibhakede(4Liter/Ibhakede) noma eyenziwe ngokwezifiso.
