Imiyalelo yePukuthengaI-PU SthandazaUmatshini wogwebu
Izixhobo zokutshiza zePolyurethane eziphezulu zoxinzelelo zingasetyenziselwa: ukugcinwa kwemizi-mveliso, ukuthintela amanzi kwi-roadbed, ubunjineli be-cofferdam, iitanki zokugcina, iingubo zombhobho, ukhuseleko lomaleko wesamente, ukuthintela amanzi kuphahla, ukungenwa manzi kwangaphantsi, ukunxitywa kwe-lining, ukugquma eludongeni kwangaphandle, ukugquma indawo ebandayo, ukugqunyelelwa kombhobho, ukugalelwa kwelanga, ulwakhiwo lokufakelwa kwe-polyurethane, njl.njl. Oomatshini bokutshiza be-polyurethane abaveliswe yinkampani basetyenziswa kwindawo ebandayo yokugcina ukutshiza, ukutshiza udonga lwangaphandle, ukutshiza kwekhareji yokutshiza, ukutshiza ngentsimbi yombala, ukugqunywa kwamanzi kunye nokutshiza, ukupholisa amagwebu elanga. oomatshini, oomatshini bokugquma amabhakethi abafaka ugwebu, itanki yamanzi egquma ugwebu, kunye neengcango neefestile ezichasene nobusela.Ukuzaliswa, ukupakishwa kwemveliso ugwebu, ukuphazamisa kunye nothotho lweemveliso ezifunxa ugwebu zonke ziyahlangabezana neemfuno zokwakha zasekhaya nezangaphandle.
Izinto eziluncedo kwimveliso ye-polyurethane ephezulu yoxinzelelo lwezixhobo zokutshiza:
1. Uxinzelelo oluphezulu lokusebenza lwezixhobo zokutshiza yi-10MPA, kwaye intloko ayikho ngaphantsi kweemitha ezingama-45;
2. Isixhobo sine-2500W inkqubo yokufudumeza kabini ukuqinisekisa ubushushu obuphezulu bokuxuba izinto eziluhlaza;
3. Izinto ezidibeneyo ze-polyurethane zixutywe ngoxinzelelo oluphezulu kwintloko yesibhamu.Ukuxuba kukhawuleza kwaye ngokulinganayo.Uxinzelelo luyakhululwa kwaye i-atomization ilungile.Umphezulu wokutshiza unokulawulwa ukuba uguquguquke malunga ne-3mm;
4. Isixhobo sixhotyiswe ngepompo yokuphakamisa izinto ezizenzekelayo njengomgangatho, okhupha ngokuzenzekelayo izinto eziluhlaza kunye nokugcina abasebenzi;
5. Isixhobo sifika ngokusemgangathweni kunye neGrass 5th generation gun ekhethekileyo yokutshiza.Iperi yentsimbi yentsimbi ithatha indawo yeplastiki yokukhuhlana kwesibini sompu wokutshiza wesizukulwana sesi-3, esihlala ixesha elide.I-nozzle eyakhelwe-ngaphakathi igwema ngokupheleleyo ukuphulwa rhoqo kwe-nozzle ye-3 yesizukulwana sompu.
Inkqubo yokwakha yokutshiza i-polyurethane
Ngaphambi kokwakhiwa kwe-polyurethane topcoat, unyango lwesiseko sesiseko kunye nokutshiza kwe-primer kuyadingeka, kulandelwa ukwakhiwa kwe-polyurethane topcoat.
1. Ukulungiswa kojongano olusisiseko
Udonga olusisiseko lufuna ukuhlangabezana neemfuno, ukunyaniseka kungaphakathi kwe-10mm kunye nomgangatho wodonga kufuneka ube ngu-5-8mm.Iindonga kufuneka zigcinwe zicocekile kwaye zicocekile, ngaphandle kwe-laitance okanye uthuli, njl.
2. Phakamisa imigca enqamlezileyo kunye nelastiki yokulawula
Ukuba i-skyscraper, kufuneka usebenzise i-theodolite ukuxhoma ucingo.Ukuba sisakhiwo esinemigangatho emininzi, udinga ipendant enkulu yocingo ukuxhoma ucingo olubhityileyo olujingayo lwentsimbi.Sebenzisa iibholithi zokwandisa phantsi kodonga oluphezulu kunye nodonga olusezantsi ukuze usebenze njengodonga olukhulu.iindawo zokuxhoma ucingo.
3. Tfutha i-foam eqinile ye-polyurethane
Sebenzisa isitshizi se-polyurethane ukutshiza ugwebu oluqinileyo lwe-polyurethane kumphezulu wodonga.Isicelo kufuneka silingane.Xa utshiza, qalisa ukusuka emphethweni, uze ulinde ukugquma, uze utshize ngomphetho onamadyungudyungu.Nika ingqalelo kwiimfuno zobunzima xa utshiza kwaye kufuneka uhambelane neenkcukacha zobunzima.Ngokuqhelekileyo, ubukhulu kufuneka bube malunga ne-10mm ngexesha lokuqala lokutshiza.Kwisambatho sesibini sokutshiza, ubukhulu kufuneka bube ngaphakathi kwe-15mm.
4. Faka udaka kwi-interface
Kwiiyure ezine emva kokuba isiseko se-polyurethane sitshiziwe, i-polyurethane interface mortar ingafakwa emva koko.Kufuneka usebenzise i-roller ukuze usebenzise ngokulinganayo udaka lwe-polyurethane kumphezulu womgangatho wesiseko se-polyurethane.Emva kokuba kugqityiwe ukutshiza, kufuneka ulinde iiyure ezilishumi elinesibini ukuya kwezingamashumi amabini anesine phambi kokuba kuqaliswe inkqubo elandelayo.
5. Ukwakhiwa kwe-anti-crack mortar layer kunye ne-face layer
1) Ukugqiba ipeyinti
2) Ngeli xesha, kuyimfuneko ukusebenzisa i-anti-crack mortar kwaye ubeke i-mesh cloth.Emva kokuba i-anti-crack mortar isetyenzisiwe, kufuneka ijongwe ukuze ibonwe ukuba ibekwe mcaba kwaye nokuba i-engile ezithe nkqo kunye ne-yin kunye ne-yang zizikwere.Naziphi na iindawo ezingekho mgangathweni kufuneka zizaliswe kwakhona kwaye zichetywe ngodaka.Emva koko, emva kokwenza umsebenzi wangaphambili, sebenzisa ipeyinti yokugqiba.Lindela de i-anti-crack mortar yome, uze uyifake.Ngeli xesha, kufuneka ubeke ingqalelo kubushelelezi.
3) Ukujongana nezitena ezijongene nazo
4) Eli nyathelo lifuna ukubeka i-hot-dip galvanized welded mesh.Emva kokuba umaleko we-insulation ugqithise ukuhlolwa kokuvunywa, sebenzisa udaka oluchasene nokuqhekeka amaxesha amaninzi, kwaye emva koko ubeke i-galvanized welded mesh.Emva kokuba i-welded mesh ibekwe, kufuneka kwakhona ihlolwe ngokufanelekileyo.Emva kokuphumelela uvavanyo, i-anti-crack mortar kufuneka isetyenziswe.
5) Izitena zeVeneer
6) Emva kokuba amanyathelo angaphambili emisebenzi yokwakha igqityiwe, unokulungiselela izitena ezijongene nazo ngeli xesha.Ubunzima bodaka lwezitena ezijongene nazo zikhethwa phakathi kwe-3mm-5mm.
