I-PU esekelwe emanzini i-PU yokunamathela emanzini, Yenziwe ngokuhlakazeka kwe-Polyurethane emanzini njengento eyinhloko yokwenza ifilimu, Ukwengeza ama-pigments nama-fillers nezinye izithasiselo.Ukwelapha ifilimu ngokushintshashintsha kwamanzi.
Ukuhlukaniswa komkhiqizo kanye nokucaciswa:
I-PU enamathela
| Ukuhlukaniswa komkhiqizo | umbala | Ukucaciswa | Indlela yokwakha |
| UV / No-UV | mhlophe | 25kg/umgqomo | I-roller, ibhulashi, i-spary
|
Isiqalo
| Ukuhlukaniswa komkhiqizo | umbala | ukucaciswa | Indlela yokwakha |
| I-primer yohlobo lwe-Reaction esekelwe emanzini | A: okumhlophe B:okuphuzi | A:10kg/umphongolo B:1kg/umphongolo | Irola/ibhulashi |
Isicelo somkhiqizo nezici:
Izinto ezisekelwe emanzini, Okuluhlaza kanye nemvelo .
Ingxenye eyodwa , ukusetshenziswa ngokushesha futhi kulula ukuyisebenzisa .
Ifilimu yokumboza inokumelana kahle namanzi, ukumelana nokugqwala okuhle kanye ne-Well imporosity.
Ukumelana ne-UV isikhathi eside.
Ifilimu yokumboza i-PU inamandla aqine kakhulu, ubude obuhle kanye nokumelana okuhle kakhulu nokushisa okuphezulu nokuphansi
Ifilimu yokumboza ihlangene futhi ikhokha izimbobo zezinaliti namabhamuza.

Ububanzi obusebenzayo:
Isicelo sokungangeni manzi kokufulela, uphahla olungaphansi komhlaba kanye ne-Metal .ukugeza kanye ne-totile njll iphrojekthi engenamanzi.
Amaphuzu okusebenza:
Ukwelashwa kwesendlalelo esiyisisekelo -I-Primer yebhulashi-Imininingwane yokwelapha yokuthuthukisa-Ukumboza ifilimu yendawo enkulu-ukuhlola ukwelashwa-ukuvala
Ukwelashwa kongqimba oluyisisekelo: ungqimba oluyisisekelo kufanele lungcoliswe futhi lome futhi aluqukethe udaka nesihlabathi, ama-litter; Ikhona langaphakathi kufanele lifakwe i-arc ebushelelezi;Bamba i-substrate uma uphahla olusha nophahla lwensimbi;
I-brush primer: Hlanganisa i-primer A no-B njengephesenti elingu-10:1, ugovuze kahle, bese Uxuba namanzi njengamaphesenti angu-30% -50%, gudluza kahle bese uxubha ku-substrate, umthamo 0.05~0.1kg/m2,isikhathi esomile 10 ~ 20min, Uma uphumule, ungasebenzisa esikhathini esizayo.
Ukwelashwa okuthuthukisiwe kwemininingwane: I-deformation seam , ukuvulwa kokuwa kwamanzi , ipayipi eliphumele ngaphandle , i-eves gutter, ne-gutter njll ingxenye , Misa ungqimba oluthuthukisiwe olungangeni manzi noma yenza izinqubo ezihambisanayo ngokuvumelana nezidingo zokwelashwa kwamaphoyinti abalulekile kanye nobunzima.
Ifilimu yokumboza yendawo enkulu : Ingakwazi ukuxubha noma ukufutha.Kumele kube shayela izikhathi ezi-2 kuya kwezi-3, Ngesikhathi sokudlula ngakunye, kufanele kulinde amahora angu-2 ~ 4, Bhulasha ngokuzayo, ukwakhiwa okuqondile.
Ukwelashwa kokuvala: ngemva kokuba indawo yongqimba engangeni manzi isiqediwe, ungqimba olungenamanzi kufanele luvalwe, ukwelashwa kokuvala kufanele kuhambisane nezidingo zokwelashwa kwamaphuzu ayisihluthulelo futhi anzima.
Ukuhlola: Yenza njengemfuneko yomthetho wendawo' ohlukile.
Ezokuthutha nesitoreji:
I-1.Imikhiqizo yezinhlobo ezahlukene noma imininingwane kufanele igcinwe ngokuhlukana ngesikhathi sokugcina nokuthutha.
2.Ngokuphikisana ne-insolation nemvula, izinga lokushisa lokugcina kufanele libe ngu-5℃-35℃.
3.Isikhathi sokugcina unyaka owodwa .
Izinyathelo zokuzivikela:
1. Awukho umsebenzi ovunyelwe ukuthi wenziwe ngezinsuku ezineqhwa nezimvula noma izinsuku ezinomoya ongu-5℃ kuya ku-35℃.
I-2.Isebenza endaweni engaphansi emanzi: umsebenzi ungenziwa endaweni yesisekelo esimanzi uma nje kungekho manzi abonakalayo endaweni yesisekelo, Ngakho-ke, ingasetshenziswa ngenkathi yemvula.Qaphela : ayikwazi ukusebenza ngaphansi kwelanga elishisayo .
3. Izinga lokushisa le-ambient lomsebenzi lizoba ngu-5℃-35℃.
4. Ngaphambi kokwakhiwa kwe-PU enamathela, Udinga i-Primer ukusingatha i-substrate.
