Upende we-Epoxy Osekelwe Emanzini Osebenza Kakhulu: Upende Wokulwa Nokugqwala

*Ukwakheka Komkhiqizo:

Upende we-epoxy osekelwe emanzini uyinhlanganisela enezici ezimbili, esebenza kahle kakhulu, enobungani nemvelo yokulwa nokugqwala, wakhiwe yi-resin ye-epoxy esuselwe emanzini eguquliwe, ama-pigment alwa nokugqwala, ama-filler, izithasiselo namanzi asusiwe i-ion, njll.,. Futhi uhlanganisa ukunamathela okuhle kakhulu, ukumelana namakhemikhali, kanye nokumelana nokugqwala kopende we-epoxy wendabuko nezinzuzo ezibalulekile zopende osuselwe emanzini, njengokuphepha kwemvelo kanye ne-VOC ephansi kakhulu. Kuyisinqumo esibalulekile sezinhlelo zokuvikela ukugqwala njengemikhumbi, amabhuloho, kanye nezakhiwo zensimbi.

*Izici Zomkhiqizo:

● Ukuvikela imvelo, kusetshenziswa amanzi njenge-VOC encane kakhulu, isitoreji nokwakhiwa okuphephile nokuzinzile, okungashisi futhi okungaqhumi.

● Ukusebenza okuhle kakhulu kokulwa nokugqwala kanye nokulwa nokugqwala.

● Ukunamathela okunamandla, ukumelana okuhle kakhulu kwe-asidi ne-alkali, ukumelana nokuncibilikisa, kanye nokumelana okuhle kakhulu nesimo sezulu.

● Ukumelana Namakhemikhali: Ifilimu yopende iqinile futhi imelana ngempumelelo nokugqwala kwamanzi, ukufuthwa ngosawoti, amafutha, izisekelo ezithambile kanye nama-asidi.

● Ukumelana nokuguga okwenziwayo okunamandla, ukumelana namanzi okuhle, ukuguquguquka okuhle kwefilimu yopende, ukumelana okunamandla kokushaywa, kanye nokuvikelwa okuhle kakhulu kwesisekelo.

*Ukusetshenziswa Komkhiqizo:

Ifanele ukuvikela ukugqwala kwesikhathi eside okuphakathi nokusindayo kwezakhiwo zensimbi kanye nemishini yemishini ezindaweni ezimaphakathi kuya kwezinobuthi obukhulu, futhi ingasetshenziswa nasezindaweni zokulungisa. Isetshenziswa kabanzi ekuvikeleni ukugqwala kwezimboni emabhulohweni, ezakhiweni zokugcina izimpahla zensimbi, ezakhiweni zensimbi ezimbonini ze-petrochemical, kagesi, kanye nezensimbi, amapayipi, amathangi okugcina (izindonga zangaphandle), izisekelo zemishini, kanye nezinye izinhlelo zokusebenza zezimboni. Iphinde isetshenziselwe ukuvikela ukugqwala kwezinhlelo zokusebenza zokuhamba njengemishini yechweba, imishini yokwakha, izimoto zezimboni, amaloli, ama-container, kanye nezimoto zempahla. Ingasetshenziswa futhi ekuvikeleni ukugqwala kwezakhiwo zangaphakathi njengezindawo zenjini yemikhumbi, izakhiwo ezinkulu, kanye namathangi e-ballast.

*Ukwelashwa Komphezulu:

Ukuqinisekisa ukunamathela kwefilimu 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.

Indawo elungisiwe kumele ihlanzeke, yome, ingabi namafutha, ingabi nothuli, futhi ifake upende zingakapheli amahora ayi-6 ngemva kokuqhumisa isihlabathi ukuze kuvinjelwe ukugqwala kwendawo.

*Imininingwane Yobuchwepheshe:

Izindinganiso Zokusebenza: HG/T 4759-2014

*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 nokuqina komklamo, futhi upende kufanele usetshenziswe ngokushesha okukhulu ukuze kuvinjelwe ukugqwala noma ukungcola kwesibili.

Isinyathelo 2: Sebenzisa i-Primer

Ukuqinisekisa umphumela ongcono wokulwa nokugqwala, sincoma ukusebenzisa i-primer eyodwa yokulwa nokugqwala, futhi kuthuthukisa ukunamathela kwi-substrate.

Isinyathelo 3: Faka upende we-Epoxy osekelwe 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, 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 ukusebenzisa ukufutha ngaphandle komoya okunomfutho ophezulu.

Ukuxubha/Ukugoqa: Ubukhulu befilimu eyomile ecacisiwe kumele bufinyelelwe.

*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.

▶ Ukuhambisana kumele kuqinisekiswe lapho kuhlanganiswa nopende olusekelwe ku-solvent (kunconywa ukuhlolwa kwendawo encane).

(kunconywa ukuhlolwa kwendawo encane).

▶ 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 noma Yenza ngokwezifiso

Isilinganiso esixubile sesisindo=5:1
