Umshini wokufafaza we-polyurethane/polyureaumkhiqizi, okokusebenza kufanelekile ukufakwa kwe-thermal, kungangeni manzi, ku-anti-corrosion, ukuthulula, njll.
Ukufafaza nge-polyurethane kudinga ukwenziwa ezindaweni eziningi.Cishe abantu abaningi baye babona inqubo yokwakha yokufafaza kwe-polyurethane, kodwa abawazi nhlobo amaphuzu okwakhiwa kwe-polyurethane spraying, futhi abazi ukuthi inqubo yobungcweti injani.Namuhla ngizokukhombisa nonke Chaza inqubo yokwakha yokufutha nge-polyurethane.

1. Ukucubungula isikhombimsebenzisi esiyisisekelo
Udonga oluyisisekelo kufanele luhlangabezane nezidingo, ukukhanya kodonga kufanele kube ngu-5-8mm, futhi ukuphakama kufanele kube phakathi kuka-10mm.
A: Udonga kufanele luhlanzwe ukuze kuqinisekiswe ukuthi udonga alukho ku-laitance, amabala kawoyela, uthuli, njll. Uma ukuphambuka kwesendlalelo sesisekelo kukhulu kakhulu, udaka kufanele lufakwe ekulinganisweni.
B: Isici esisodongeni silungiswe ngosimende.
C: Uma udonga lungaphezu noma lulingana no-10mm, kufanele lususwe.
D: Amapayipi agqitshiwe, amabhokisi ocingo kanye nezingxenye ezishunyekiwe odongeni kufanele zifakwe kusenesikhathi, futhi umthelela wogqinsi longqimba lokufakelwa kufanele kucatshangelwe.
E: Ngaphambi kokufafaza igwebu eliqinile le-polyurethane, sebenzisa ifilimu yepulasitiki, iphephandaba likadoti, ibhodi lepulasitiki noma ibhodi lezinkuni, i-plywood ukumboza nokuvikela amafasitela, izicabha nezinye izinto ezinganandisi.Umnyango wophahla kanye nohlaka lwefasitela kufanele lufafazwe ngegwebu eliqinile le-polyurethane ngaphambi kokufakwa ukuze kugwenywe ukungcola.

2. Ulayini wokulawula ovundlile nokunwebeka olengayo
Amabhawodi okunweba abekwa ngaphansi kodonga olungaphezulu nodonga olungezansi njengendawo yokulenga yocingo olukhulu olulengayo.I-theodolite isetshenziselwa ukufaka ucingo olulengayo lwezakhiwo eziphakeme, futhi ucingo olukhulu lusetshenziselwa izakhiwo ezinezitezi eziningi ukulenga ucingo oluncane olulengayo, futhi luqinise ngocingo oluqinisayo.Faka imigqa eqondile yensimbi ekhoneni elikhulu le-yin ne-yang odongeni, futhi ibanga phakathi kwemigqa eqondile yensimbi kanye nodonga ubukhulu bengqikithi yongqimba olushisayo.Ngemva kokulenga umugqa, qala uhlole ukucaba kodonga ngerula yebha engu-2m esitezi ngasinye, bese uhlola ukuma kodonga ngebhodi lokusekela elingu-2m.Le phrojekthi ingenziwa kuphela uma izidingo ze-flatness zifinyelelwa.

3. Ukufafaza i-foam eqinile ye-polyurethane
Vula umshini wokufafaza we-polyurethane ukuze ufafaze i-foam eqinile ye-polyurethane ngokulinganayo odongeni.
IMP: Ukufafaza kufanele kuqale onqenqemeni, emva kokukhihliza amagwebu, fafaza onqenqemeni olunamagwebu.
B: Ubukhulu besifutho sokuqala kufanele bulawuleke cishe ngo-10mm.
C: Ubukhulu bokudlula kwesibili kufanele bulawuleke ngaphakathi kwe-15mm kuze kube ubukhulu obudingwa umklamo.
D: Ngemuva kokuthi ungqimba lwe-polyurethane oluqinile lwe-foam lufuthwe, ukujiya kongqimba lokufakelwa kufanele kuhlolwe njengoba kudingekile, futhi ukuhlolwa kwekhwalithi kufanele kwenziwe ngokuvumelana nezidingo zeqoqo lokuhlola lamarekhodi okuhlola.
E: Ngemva kokufafaza ungqimba lokufakwa kwe-polyurethane imizuzu engu-20, sebenzisa i-planer, isaha lesandla namanye amathuluzi ukuze uqale ukuhlanza, ukuphungula ukuthungatha, ukuvikela izingxenye kanye nezingxenye eziphumela ngaphandle ezidlula ubukhulu obubekiwe ngo-1cm.

4. Ukudweba udaka lwesixhumi esibonakalayo
Ukwelashwa kodaka lwe-polyurethane interface kwenziwa emahoreni ama-4 ngemuva kokufuthwa kwesisekelo se-polyurethane, futhi udaka lwesixhumi esibonakalayo lungambozwa ngokulinganayo kungqimba oluyisisekelo lwe-polyurethane insulation nge-roller.Ukuze uqinise inhlanganisela phakathi kongqimba lwe-insulation kanye nongqimba oluyisicaba, vimbela ukuqhekeka nokuwa, futhi uvikele ungqimba lokufakwa kwe-polyurethane ekuchayekeni elangeni futhi lubangele ukuphuzi nokuchaki.Ngemva kokufafaza udaka lwe-polyurethane interface amahora angu-12-24, ukwakhiwa kwenqubo elandelayo kwenziwa.Qaphela ukuthi udaka lwe-polyurethane interface alukwazi ukufuthwa ngezinsuku zemvula.

5. Ukwakhiwa kongqimba lwe-anti-cracking nosendlalelo sokuqeda
(1) Ukuphela kopende
①Faka udaka olumelana nokuqhekeka bese wendlalela indwangu enezikhala engazweli nge-alkali.Imeshi emelana ne-alkali icishe ibe ngu-3m ​​ubude, futhi usayizi usikwa ngaphambili.I-anti-cracking mortar ngokuvamile iqedwa ngamaphasi amabili, ngogqinsi oluphelele olungaba ngu-3mm kuya ku-5mm.Ngokushesha ngemva kokusula udaka olumelana nokuqhekeka ngendawo elingana nendwangu ye-mesh, cindezela indwangu ye-alkali engazweli ngensimbi yensimbi.Ububanzi obugqagqene phakathi kwezindwangu ezinezikhala ezimelana ne-alkali akumele zibe ngaphansi kuka-50mm.Cindezela ngokushesha indwangu enezikhala engamelana ne-alkali enetrowel yensimbi ngokulandelana ukusuka kwesokunxele uye kwesokudla futhi ukusuka phezulu kuye phansi, futhi ukugqagqana okomile akuvunyelwe ngokuqinile.Amakhona e-yin ne-yang kufanele futhi agqitshwe, futhi ububanzi bokugqagqana kufanele bube ngu-≥150mm, futhi isikwele nokuma kwamakhona e-yin ne-yang kufanele kuqinisekiswe.Indwangu enezikhala engazweli nge-alkali kufanele iqukethwe odakeni oluvimbela ukuqhekeka, futhi ukugandaya kufanele kube bushelelezi futhi kungabi nemibimbi.I-mesh ingabonakala ngokucacile, futhi udaka lugcwele.Izingxenye ezingagcwali kufanele zigcwaliswe ngokushesha ngodaka olulwa nokuqhekeka okwesibili ukuze lube sezingeni futhi luhlangene.
Ngemva kokuqedwa kokwakhiwa kodaka lwe-anti-crack, hlola ukushelela, ukuma kanye nesikwele samakhona e-yin ne-yang, futhi usebenzise udaka olulwa nokuqhekeka ukuze lulungiswe uma lungahlangabezani nezidingo.Kunqatshelwe ngokuphelele ukusebenzisa ukhalo olujwayelekile lukasimende, imikhono yamafasitela, njll.
②Khupha i-putty ekwazi ukumelana namanzi bese usebenzisa upende wokuqeda.Ngemuva kokuthi ungqimba olumelene nokuqhekeka selomile, hlambulula i-putty engavimbeli amanzi eguquguqukayo (ephumelele izikhathi eziningi, ubukhulu bokukhuhla ngakunye kulawulwa cishe ku-0.5mm), futhi ukumboza kokuqeda kufanele kube bushelelezi futhi kuhlanzeke.
(2) Ukuqedwa kwezitini
①Faka udaka olukwazi ukumelana nokuqhekeka bese usakaza i-hot-dip galvanized wire mesh.
Ngemuva kokuthi ungqimba lokufakelwa luhloliwe futhi lwamukelwe, i-anti-cracking mortar isetshenziswa, futhi ubukhulu bulawulwa ku-2mm kuya ku-3mm.Sika i-hot-dip galvanized wire mesh ngokosayizi wesakhiwo, futhi uyibeke ngezigaba.Ubude be-hot-dip galvanized wire mesh akumele budlule u-3m.Ukuze kuqinisekiswe ikhwalithi yokwakhiwa kwamakhona, i-hot-dip galvanized welded wire mesh emakhoneni igoqwa ngaphambili ibe yi-engeli elungile ngaphambi kokwakhiwa.Enkambweni yokusika i-mesh, i-mesh akufanele igoqwe ibe yizicucu ezifile, futhi isikhwama se-mesh akufanele sakhiwe ngesikhathi sokubeka.Ngemuva kokuvulwa kwe-mesh, kufanele ibekwe phansi ngokushintshana.I-zinc eshiselwe i-wire mesh ukuze iyenze ibe seduze nendawo yodaka olunqanda ukuqhekeka, bese ubamba i-hot-dip galvanized wire mesh odongeni oluyisisekelo ngamabhawodi okunwetshwa enayiloni.Gcwalisa ukungalingani ngesiqeshana esimise okuka-U.Ububanzi bethanga phakathi kwamameshi ashiselwe ama-hot-dip akumele bube ngaphansi kuka-50mm, inani lezendlalelo ezigqagqene akufanele libe likhulu kuno-3, futhi amalunga ethango kufanele ahlanganiswe neziqeshana ezimise oku-U, izintambo zensimbi noma amabhawodi okusetshenzwa kulengwa.Izinzipho zikasimende kanye nama-gaskets kufanele kufakwe ekugcineni kwe-hot-dip galvanized welded wire mesh ohlangothini olungaphakathi lwefasitela, udonga lohlaka lwepharaphethi, indawo yokuhlala, njll., ukuze i-hot-dip galvanized galvanized wire mesh ingagxilwa. isakhiwo esikhulu.
Ngemuva kokuthi i-hot-dip galvanized welded mesh isibekiwe futhi yadlula ukuhlolwa, udaka olulwa nokuqhekeka luzosetshenziswa okwesibili, futhi i-hot-dip galvanized welded mesh yocingo izosongwa odakeni lwe-anti-crack.Ungqimba olungaphezulu lodaka oluqhekekile kufanele luhlangabezane nezidingo zokuthi flat kanye nokuma mpo.
②Ithayela le-veneer.
Ngemuva kokuthi ukwakhiwa kwe-anti-crack mortar kuqediwe, kufanele kufafazwe kahle futhi kuphulukiswe, futhi inqubo yokunamathisela i-veneer tile ingenziwa ngemva kwezinsuku ezingaba ngu-7.Ubukhulu bodaka lokuhlanganisa izitini kufanele bulawuleke phakathi kuka-3mm kuya ku-5mm.
