Iinkcazo zemvelisoI-SWD9001 desalination caisson special polyurea ngumxholo oqinileyo we-100% wemathiriyeli ye-polyurea elastomer.Ine-anticorrosion ephezulu kunye nokumelana nokhukuliseko kumanzi olwandle kunye nokumelana okuphezulu kwe-cathodic disbonding.Isetyenziswe ngokubanzi kwiiprojekthi zobunjineli ezinkulu zokukhupha ityuwa eMelika, eOstreliya naseTshayina yasekhaya.
Izicelo zeMveliso
I-Anticorrosion ukukhusela amanzi kwiitanki zokususa ityuwa emanzini olwandle, i-offshore wharf kunye nezinye izixhobo zaselwandle.Inokumelana neekhemikhali eziphezulu, i-anticorrosion waterproof kunye nokumelana namanzi olwandle, ukwandisa ubomi benkonzo ngaphezu kweminyaka engama-30.

Inqaku lesicelo
Dlulisa iyunifomu yecandelo B phambi kokufakwa, xuba ngokucokisekileyo ii-pigments ezifakiweyo, okanye umgangatho wemveliso uya kuchaphazeleka.
fafaza i-polyurea ngexesha elifanelekileyo ukuba umphezulu we-substrate ulungiselelwe.Indlela yesicelo kunye nexesha lekhefu le-SWD polyurea speical primer nceda ubhekiselele kwenye incwadana yeenkampani ze-SWD.
Hlala ufaka i-SWD yokutshiza i-polyurea kwindawo encinci ngaphambi kokuba isicelo esikhulu sihlolisise umlinganiselo wokuxuba, umbala kunye nesiphumo sokutshiza zichanekile.Ngolwazi oluthe vetshe ngesicelo nceda ujonge kwiphepha lemiyalelo lamva nje leimiyalelo yokusetyenziswa kwe-SWD spray polyurea series.
Ixesha lokunyanga imveliso
| Ubushushu be-substrate | Yomile | Ukuhamba ngamandla | qinisa ngokupheleleyo |
| +10℃ | 28s | 45min | 7d |
| +20℃ | 20s | 15min | 6d |
| +30℃ | 17s | 5min | 5d |
Qaphela: ixesha lokunyanga liyahluka ngokwemeko yokusingqongileyo ingakumbi iqondo lobushushu kunye nokufuma okunxulumeneyo.
Beka ubomi kwishelufa
* Ukususela kumhla womenzi kunye nakwipakethe yokuqala etywiniweyo:
Icandelo A: Iinyanga ezili-10
Icandelo B: iinyanga ezili-10
*ubushushu bokugcina:+5-35°C
Ukupakisha: Icandelo A 210kg / igubu, inxalenye B 200kg / igubu
Qinisekisa ukuba iphakheji yemveliso itywinwe kakuhle.
