Upende Wokulwa Nokugqwala Osekelwe Emanzini Osezingeni Lobungcweti We-Polyurethane

*Ukwakheka Komkhiqizo:

Upende we-polyurethane ovikela ukugqwala osekelwe emanzini uyinhlanganisela yezingxenye ezimbili equkethe i-resin ye-polyurethane ethwala amanzi engeniswa kwamanye amazwe, imibala engamelani nesimo sezulu, izithasiselo ezahlukahlukene, kanye ne-agent yokwelapha evikela ukugqwala esekwe emanzini, inokusebenza okuhle kakhulu kokulwa nokugqwala futhi inobungani nemvelo. Lo mkhiqizo unokuqukethwe okuphansi kakhulu kwe-VOC, okuhlangabezana nezidingo zesimanje zokuvikela imvelo ngenkathi unikeza ukusebenza okuvikelayo okufana nokwembozwa okusekelwe ku-solvent yendabuko.

*Izici Zomkhiqizo:

● Ukusebenzisa amanzi njengesihlanzi, angenaphunga, angangcolisi, angashisi futhi angaqhumi.

● Ukumelana nokuphuzi, ukumelana nesimo sezulu okuhle, ukucwebezela okuhle kanye nokugcinwa kombala.

● Ukucwebezela okuphezulu nokukhuluphala okuhle.

● Ukunamathela okuhle kakhulu, ubulukhuni obuphezulu, ukumelana nokuguguleka okuphezulu.

● Ukumelana okuhle kakhulu namanzi, uwoyela, isinyibilikisi kanye namakhemikhali.

● Ukumelana okuhle nokushisa nomswakama kanye nesifutho sikasawoti.

*Ukusetshenziswa Komkhiqizo:

Upende we-polyurethane oqhutshwa ngamanzi usetshenziswa kabanzi kuma-topcoat angaphandle ahlobisayo anezidingo eziphezulu zokubukeka, njengemishini, amathangi okuxuba, amabhuloho, amathangi okugcina izinto, izitsha, imikhumbi, ikakhulukazi izimoto. Angasetshenziswa futhi ekumbozweni kwepulasitiki, anikeze ukumbozwa okunemibala nokuvikela kwemikhiqizo yepulasitiki efana nama-casing emikhiqizo kagesi, amathoyizi, kanye nezinto zasekhaya.

*Imininingwane Yobuchwepheshe:

*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.

*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.

*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: Sebenzisa i-Primer

Ukuqinisekisa ukuthi i-anticorrosion ingcono, phakamisa i-primer eyodwa yokulwa nokugqwala, ingathuthukisa ukunamathela kwi-substrate futhi inezakhiwo ezinhle kakhulu zokuvikela ukugqwala.

Isinyathelo 3: Faka upende we-Polyurethane 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.)

*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-≤80%.

▶ 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: 20kg/ibhakede, I-Hardener/i-ejenti yokwelapha: 4Kg/ibhakede noma wenze ngezifiso
