Polyurethane/polyurea umatshini wokutshizaumenzi, izixhobo zifanelekile kwi-thermal insulation, i-waterproof, i-anti-corrosion, ukugalela, njl.
Ukutshiza nge-polyurethane kufuneka kwenziwe kwiindawo ezininzi.Mhlawumbi abantu abaninzi baye babona inkqubo yokwakhiwa kwe-polyurethane yokutshiza, kodwa abaqondi ngokupheleleyo kwiindawo zokwakha zokutshiza i-polyurethane, kwaye abazi ukuba yintoni inkqubo yobugcisa.Namhlanje ndiza kukubonisa nonke Cacisa inkqubo yokwakhiwa kwe-polyurethane yokutshiza.

1. Ukulungiswa kojongano olusisiseko
Udonga olusisiseko lufanele luhlangabezane neemfuno, ukunyanzeliswa kodonga kufuneka kube ngu-5-8mm, kwaye ukuphakama kufuneka kube ngaphakathi kwe-10mm.
A: Udonga kufuneka lucocwe ukuze luqinisekise ukuba udonga lukhululekile kwi-laitance, i-oil stains, uthuli, njl.
B: Isiphene eseludongeni silungiswe ngodaka lwesamente.
C: Xa udonga lodonga lukhulu okanye lulingana no-10mm, kufuneka lususwe.
D: Imibhobho engcwatyiweyo, iibhokisi zocingo kunye neendawo ezifakwe eludongeni kufuneka zifakwe kwangaphambili, kwaye impembelelo yobunzima bomgangatho we-insulation kufuneka ithathelwe ingqalelo.
E: Ngaphambi kokutshiza i-polyurethane i-foam eqinile, sebenzisa ifilimu yeplastiki, iphephandaba lenkunkuma, ibhodi yeplastiki okanye ibhodi yeplanga, i-plywood yokugubungela kunye nokukhusela iifestile, iingcango kunye nezinye izinto ezingagqunywanga.Umnyango wophahla kunye nesakhelo sefestile kufuneka sitshizwe nge-polyurethane eqinile ye-foam phambi kokufakwa ukuphepha ukungcola.

2. Ukuxhoma umgca wokulawula othe tye kunye ne-elastic
Iibholiti zokwandisa zibekwe phantsi kodonga oluphezulu kunye nodonga olusezantsi njengendawo yokuxhoma yocingo olukhulu olujingayo.I-theodolite isetyenziselwa ukufakela ucingo olujingayo kwizakhiwo eziphakamileyo, kwaye ucingo olukhulu lusetyenziselwa izakhiwo ezinemigangatho emininzi ukuxhoma ucingo olubhityileyo olujingayo, kwaye luluqinise ngocingo oluqinisayo.Faka imigca emi nkqo yentsimbi kwikona enkulu yeyin kunye neyang eludongeni, kwaye umgama phakathi kwemigca ethe nkqo yentsimbi kunye nodonga bubunzima bubonke bomaleko wokugquma kwe-thermal.Emva kokuxhoma umgca, jonga kuqala i-flatness yodonga kunye nomlawuli we-bar ye-2m kumgangatho ngamnye, kwaye ukhangele ukuqina kodonga ngebhodi yokuxhasa i-2m.Iprojekthi inokuqhutywa kuphela xa iimfuno ze-flatness zifezekisiwe.

3. Ukutshiza i-polyurethane ye-foam eqinile
Vula umatshini wokutshiza we-polyurethane ukutshiza i-foam eqinile ye-polyurethane ngokulinganayo eludongeni.
A: Ukutshiza kufuneka kuqale ukusuka emphethweni, emva kokuba ugwebu, utshize ecaleni komphetho wegwebu.
B: Ubukhulu besitshizi sokuqala kufuneka bulawuleke malunga ne-10mm.
C: Ubuninzi bokupasa kwesibini kufuneka balawulwe ngaphakathi kwe-15mm kude kube ubukhulu obufunwa yi-design.
D: Emva kokuba i-polyurethane engqongqo ye-foam insulation layer ifafaziwe, ubukhulu be-insulation layer kufuneka buhlolwe njengoko kufuneka, kwaye ukuhlolwa komgangatho kufuneka kuqhutywe ngokweemfuno zebhetshi yokuhlola kwiirekhodi zokuhlola.
E: Emva kokutshiza i-polyurethane insulation layer yemizuzu engama-20, sebenzisa iplani, isarha yesandla kunye nezinye izixhobo zokuqalisa ukucoca, ukunqumla i-shading, ukukhusela iinxalenye kunye neendawo eziphumayo ezidlula ubukhulu obuchaziweyo nge-1cm.

4. Ukupeyinta udaka lojongano
Unyango lwe-polyurethane yodaka lwe-interface lwenziwa kwiiyure ezi-4 emva kokuba isiseko sesiseko se-polyurethane sitshizwe, kwaye i-interface mortar inokufakwa ngokulinganayo kwi-polyurethane insulation base layer nge-roller.Ukomeleza indibaniselwano phakathi kwe-insulation layer kunye ne-flat layer, thintela ukuqhekeka kunye nokuwa, kwaye unqande umaleko wokugquma we-polyurethane ekukhanyeni kwelanga kwaye ubangele ukutyheli kunye nokuchaki.Emva kokutshiza i-polyurethane interface yodaka kwiiyure ezingama-12-24, ukwakhiwa kwenkqubo elandelayo kuqhutyelwa.Qaphela ukuba i-polyurethane interface yodaka ayinakutshizwa ngeentsuku zemvula.

5. Ukwakhiwa kwe-anti-cracking mortar layer kunye nokugqiba
(1) Ukupeyinta ukugqiba
①Faka udaka olumelana nokuqhekeka kwaye ungqengqe phantsi ilaphu lemesh elimelana nealkali.Umnatha onganyangekiyo wealkali umalunga ne-3m ubude, kwaye ubungakanani bunqunywe kwangaphambili.Udaka oluchasene nokuqhekeka lugqitywa ngokubanzi ngeendlela ezimbini, kunye nobukhulu obupheleleyo malunga ne-3mm ukuya kwi-5mm.Kwakamsinyane emva kokusula udaka olukwaziyo ukumelana nokuqhekeka kwendawo elingana nelaphu elinomnatha, cofa ilaphu elinomnatha elimelana nealkali ngetrowel yentsimbi.Ububanzi obudlulayo phakathi kwamalaphu e-alkali-resistant mesh kufuneka angabi ngaphantsi kwe-50mm.Kwangoko cinezela ilaphu le-alkali-resistant mesh kunye ne-iron trowel ngokulandelelana ukusuka ekhohlo ukuya ekunene kwaye ukusuka phezulu ukuya ezantsi, kwaye ukugqithelana okomileyo akuvumelekanga ngokungqongqo.Iikona ze-yin kunye ne-yang kufuneka zigqithene, kwaye ububanzi bokugqithelana kufuneka bube ≥150mm, kwaye isikweri kunye nokuthe nkqo kweekona ze-yin kunye ne-yang kufuneka ziqinisekiswe.Umnatha onganyangekiyo kwi-alkali kufuneka uqukwe kwi-anti-cracking mortar, kwaye i-paving kufuneka igudileyo kwaye ingabi nemibimbi.Umnatha unokubonwa ngokucacileyo, kwaye udaka lugcwele.Amacandelo angagcwaliyo kufuneka azaliswe ngokukhawuleza ngodaka oluchasene nokuqhekeka okwesibini ukuya kwinqanaba kunye nokudibanisa.
Emva kokuba ukwakhiwa kodaka lwe-anti-crack kugqityiwe, jonga ukugudiswa, ukuqina kunye nesikwere seekona ze-yin kunye ne-yang, kwaye usebenzise i-anti-crack mortar ukulungiswa ukuba ayihambisani neemfuno.Akuvunyelwe ngokungqongqo ukusebenzisa isinqe esiqhelekileyo se-sement mortar, imikhono yefestile, njl.
②Khupha iputty enganyangekiyo emanzini kwaye usebenzise ipeyinti yokugqiba.Emva kokuba i-anti-cracking layer yomile, gxobhoza i-putty eguquguqukayo enganyangekiyo yamanzi (iphumelele ngamaxesha amaninzi, ubukhulu be-scraping nganye bulawulwa malunga ne-0.5mm), kwaye ukugqitywa kokugqiba kufuneka kube lula kwaye kucoceke.
(2) Ukugqitywa kwezitena
①Faka udaka olumelana nokuqhekeka kwaye usasaze umnatha wocingo olushushu lwediphu.
Emva kokuba i-insulation layer ihlolwe kwaye yamkelwe, i-anti-cracking mortar isetyenziswe, kwaye ubukhulu bulawulwa kwi-2mm ukuya kwi-3mm.Sika i-hot-dip galvanized galvanized wire mesh ngokobungakanani besakhiwo, kwaye uyibeke kumacandelo.Ubude bomnatha wocingo olufakwe emazingeni ashushu akufunekanga budlule kwi-3m.Ukuze kuqinisekiswe umgangatho wokwakhiwa kweekona, i-hot-dip galvanized galvanized welded wire mesh kwiikona sele isongwe ngaphambili kwi-angle efanelekileyo ngaphambi kokwakhiwa.Kwinkqubo yokusika i-mesh, i-mesh ayifanele ifakwe kwiifolthi ezifileyo, kwaye i-pocket ye-mesh ayifanele yenziwe ngexesha lokubeka.Emva kokuba i-mesh ivuliwe, kufuneka ibekwe phantsi ngokulandelelanayo.Zinc welded wire mesh ukuyenza isondele kumphezulu we-anti-crack mortar, kwaye emva koko i-ankile i-hot-dip galvanized galvanized welded wire mesh kudonga olusisiseko kunye neebholiti zokwandisa inayiloni.Gcwalisa ukungalingani ngekliphu emilise u-U.Ububanzi bethango phakathi kwe-hot-dip galvanized meshes welded akufunekanga ibe ngaphantsi kwe-50mm, inani leeleya ezigqitheneyo akufanele libe likhulu kune-3, kwaye i-lap joints kufuneka ilungiswe kunye neekliphu ze-U, iingcingo zentsimbi okanye iibholiti ze-ankile.Izikhonkwane zesamente kunye neegaskets kufuneka zifakwe ekupheleni komnatha wocingo oshushu-diphu ofakwe ngaphakathi efestileni, udonga lweparapet, indawo yokuhlala edibeneyo, njl.njl., ukuze i-hot-dip galvanized galvanized welded wire mesh inokumiswa. isakhiwo esiphambili.
Emva kokuba i-hot-dip galvanized galvanized wire mesh ibekwe kwaye iphumelele ukuhlolwa, i-anti-crack mortar iyakusetyenziswa okwesibini, kwaye i-hot-dip galvanized galvanized wire mesh iya kusongelwa kwi-anti-crack mortar.Umaleko wodaka oluqhekekileyo kufuneka ufezekise iimfuno ze-flatness kunye nokuqina.
②Ithayile yeveneer.
Emva kokuba ukwakhiwa kwe-anti-crack mortar kugqitywe, kufuneka kutshizwe ngokufanelekileyo kwaye kuphiliswe, kwaye inkqubo yokunamathisela i-tile ye-veneer inokuqhutywa emva kweentsuku ezi-7.Ubunzima bodaka lokudibanisa izitena kufuneka balawulwe ngaphakathi kwe-3mm ukuya kwi-5mm.
