I-Epoxy Anti Corrosive Primer esekelwe emanzini (izingxenye ezimbili)

*Incazelo Yomkhiqizo:

Kuyi-coating enezingxenye ezimbili, eyenziwe nge-resin ye-epoxy egeleza emanzini, ama-pigment kanye nama-filler, ama-auxiliary, amanzi angenawo ama-ion njalo njalo.

*Izici Zomkhiqizo:

● Okulwa nokugqwala nokugqwala: Faka imibala elwa nokugqwala ukuze uvimbele ngempumelelo umswakama nomoya-mpilo, ubambezele ukugqwala kwezinsimbi zensimbi, futhi zifanele izindawo ezinomswakama;

● Ifilimu inokumelana kwamanzi okuhle kakhulu kanye nokusebenza kahle kokulwa nokugqwala;

● Ukunamathela okuqinile: Izingxenye ze-resin ye-epoxy zinganamathela ngokuqinile ezinhlotsheni ezahlukahlukene ze-substrate (kufaka phakathi insimbi nokhonkolo), zixazulule izinkinga zokusikwa nokugoba ungqimba lwesisekelo;

*Ukusetshenziswa Komkhiqizo:

Ifaneleka njenge-primer yokulwa nokugqwala kanye nokulwa nokugqwala ezindaweni eziyisisekelo ezifana nokhonkolo, insimbi, ishidi le-galvanized, i-aluminium alloy, njll., futhi isetshenziswa kabanzi ekwakheni, amabhuloho, amapayipi angaphansi komhlaba, imishini yezimboni, imishini ye-hydraulic, imishini yamakhemikhali, imishini yemishini, izakhiwo zensimbi zokwakha, izitshalo zamandla okushisa, izikhungo zamandla enuzi, imibhoshongo yomoya kanye namafutha ahlukahlukene, amagesi ahlanzekile kakhulu kanye namathangi okugcina amakhemikhali e-organic.

*Imininingwane Yobuchwepheshe:

Izindinganiso Zokusebenza: HG/T4759-2014

*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.

Isinyathelo 2: Faka i-Epoxy Primer Esekelwe Emanzini

Ngemva kokuvula ibhakede, hlanganisa ngokulinganayo nge-mixer kagesi kuze kube yilapho umbala kanye ne-viscosity kufana, uthele kancane kancane ingxenye B (i-ejenti yokwelapha) engxenyeni A (upende), ngokuphelele ngokwesilinganiso esibekiwe (ngesisindo). Ngemva kokuxuba ngokuphelele, vumela ingxube ime imizuzu emi-5-10 ukuze ivuthwe. Bese uhlanganisa ungqimba oluxubile lusetshenziswe 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 nendlela yokusebenza.)

Qaphela:

*Uma kudingeka ukunciphisa ukuze kusetshenziswe kahle, engeza amanzi kancane kancane ngenkathi uxuba. Isilinganiso sokuxuba esingu-10-15% ngesisindo. Ukunciphisa ngokweqile kuzothinta kabi ukwakheka kwefilimu, amandla okufihla, kanye nokuqina kwesikhathi eside. Lungisa i-viscosity ukuze ivumelane nendlela ethile yokufaka (ukuxubha, ukugoqa, noma ukufafaza).

* 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.

*Indlela Yokwakha:

Ukufutha: Ukufutha ngaphandle komoya noma ukufutha ngomoya. Kunconywa ukusebenzisa ukufutha ngaphandle komoya okunomfutho ophezulu.

Ukuxubha/Ukugoqa: Ubukhulu befilimu eyomile ecacisiwe kumele bufinyelelwe.

*Upende Ohambisanayo:

Kunconywa ukusebenzisa upende ophakathi we-epoxy osekelwe emanzini kanye ne-topcoat ye-acrylic/polyurethane esekelwe emanzini ukwakha uhlelo lokumboza oluhlanganisiwe lwe-"primer-intermediate-topcoat" ukuze kufezwe ukuvikelwa kokugqwala kwesikhathi eside kanye nezinjongo zokuhlobisa nokwandisa impilo yokumboza iyonke.

*Izinyathelo zokuzivikela:

▶ Izinga lokushisa lokwakha lingu-5℃-35℃ (Ukulungiswa okuqondile kwenziwa ngokwezici zomkhiqizo, umswakama u-≤85%.

▶ 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 Nokuphila Kwakho:

▅ 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: 20 kg/Ibhakede; I-ejenti yokwelapha: 4 kg/Ibhakede

Isilinganiso esixubile sesisindo=5:1
