Iinkcukacha zeMveliso

Ukuqulunqwa kwemveliso

I-polyurethane ye-foam etshiziweyo ibubungqina bamanzi, igcina ubushushu kunye ne-foam ekhusela ubushushu eyenziwe ngokuxuba amacandelo A kunye no-B ngomlinganiselo othile kwaye ifumana uthotho lweekhemikhali.

▲Isixhobo sesixhobo

Isixhobo se-A yimathiriyeli edityanisiweyo eyenziwe yipolyol (i-polyether edibeneyo okanye i-polyester) kunye namanzi, i-catalyst, i-stabilizer, i-flame retardant kunye nezinye izongezo, eziqhelekileyo ezaziwa njengemathiriyeli emhlophe.

▲B izinto eziphathekayo

Elona candelo liphambili le-B-component material yi-isocyanate, elulwelo olumdaka ngebala, olubizwa ngokuba yi-black material.

Amanzi apheleleyo B1 grade yokutshiza eqinile polyurethane (PU) inkqubo yokugcina ebandayo yokugcina

Ukutshiza okuqinileyo kogwebu lwepolyurethane kusekwe kwi-onisocyanate (izinto ezimdaka ezimdaka) kunye neepolyols (ezaziwa njengezinto ezimhlophe njengezinto ezimhlophe ezixutywe nee-catalysts, modifiers, anti-aging agents.I-phosphorus nitrogen retardants yomlilo (uphando oluzimeleyo kunye nokuncipha), amanzi (uphando oluzimeleyo kunye nophuhliso) kunye nezinye izongezo (eyaziwa ngokuba ziimathiriyeli ezimhlophe).Ukuxubana okufanayo, ukutshiza ngoxinzelelo oluphezulu, kunye ne-sitefoaming zenza uhlobo olutsha lwe-polymerthermal insulation ephezulu yemolekyuli kunye nemathiriyeli engangenwa manzi.Isebenza ngokugqwesileyo kwi-thermal insulation kunye nokusebenza kakuhle kwamanzi. ugwebu lwemveli oluqinileyo, alunafluorine, alunatyhefu kwaye alunangcoliseko lokwenene B1 polyurethane ugwebu oluqinileyo.

Iphaneli yesandwich yePolyurethane (PUR) inkqubo yokugquma ebandayo yokugcina

Sitshiza inkqubo edibeneyo yokufulela i-polyurethane yokugcina amandla, ukugcinwa kobushushu kunye nokuthintela amanzi

Iiphaneli zesangweji yePolyurethane (i-PUR) zisebenzisa iiphaneli ze-foampolyurethane ezomeleleyo (okanye i-polyurethane eguquliweyo) njengezinto zokufakelwa kwe-thermalinsulation., Ireyithingi yomlilo ibalasele ngakumbi., kunye nobubanzi besicelo banzi.

Ukufakwa kwe-Flat roof insulation kwizakhiwo ezitsha kunye nezikhoyo yenye yezona ndawo ziphambili zesicelo se-sprayed rigidpolyurethane foam.

Uqheliselo lubonakalise ukuba ukutshiza ugwebu oluqinileyo lwe-polyurethane ukufudumeza uphahla kunokonga i-80% yexesha kunye ne-50% yeendleko zotyalo-mali xa kuthelekiswa neendlela eziqhelekileyo zokugquma ubushushu. udonga lweparapet, ukutshiza kunokuqhutywa ngokulula.Ukutshiza i-foam eqinile i-polyurethane inokunyanga ngokukhawuleza kwaye inokuhamba kuyo emva kwemizuzu engamashumi amabini.Unokukhetha ukusebenzisa ngokuthe ngqo umaleko omncinci okhuselayo wefilimu onokuxhathisa imitha ye-ultraviolet kumphezulu we-foam yokutshiza.

Ukutshiza i-polyurethane ye-foam eqinile kunokuba lula kwaye ngokukhawuleza ukutshizwa kuphahla olomileyo nolungenathuli.

Tshafaza ngaphandle kokonga umbane eludongeni lwepolyurethane, ukugcina ubushushu kunye nenkqubo edityanisiweyo yokungangeni kwamanzi

Izinto ezilungileyo zokutshiza i-foam eqinile ye-polyurethane yokugquma udonga lwangaphandle:

I-1.Ukusebenza kakuhle kokugcinwa kobushushu kunye ne-conductivity ephantsi ye-thermal

2.Uzinzo oluphezulu lwe-dimensional, akukho kugoba, akukho mfazwe, akukho kuguqulwa

3.Ubomi benkonzo ende (ubomi benkonzo efanayo njengoko isakhiwo sinokusetyenziswa)4.Ulwakhiwo olufanelekileyo, ukusetyenziswa okubanzi kunye nexesha elifutshane lokwakha

I-5.Amandla okubambisana okunamandla, ukudibanisa okudibeneyo, akukho mgodi, akukho kuphazamiseka kwaye akukho ukuwa

6. Ukusebenza kakuhle kwamanzi, isakhiwo seseli evaliweyo ngokubanzi

7.I-non-fluorine, ayinayo ityhefu kwaye ayingcolisi

8.Ukusebenza okuphezulu kwe-flame retardant, izinto zokwenyani zeB1

Udonga olujingayo lomkhusane wokonga umbane wangaphandle

Inkqubo yokufakelwa kwe-thermal yangaphandle emva kodonga lwamakhethini okanye i-dry-hanging yangaphandle ye-thermal insulation system yodonga lwamakhethini ingasetyenziselwa ukulungiswa kwezakhiwo ezitsha kunye nezakhiwo ezikhoyo.I-metal orstone surface layer of the dry-hanging curtain wall system inokukhusela amacandelo angaphandle eludongeni kwimozulu, kwaye ingasetyenziselwa njenge-facade yesakhiwo sokuhlobisa ukunika abaqulunqi ukhetho olungakumbi.

Okokuqala lungisa iindawo ezidibeneyo zenkqubo yodonga lwamakhethini eludongeni, kwaye emva koko utshize i-foam eqinile ye-polyurethaneajikeleze udonga kunye neendawo ezifakwe ngaphakathi.Ngokohlobo lwendonga eyomileyo yokuxhoma ikhethini, i-keel ethe nkqo okanye umzila we-aluminurguide unokufakwa ukulungisa nokufaka udonga lwamakhethini.Gcina umaleko wokuphefumla oyi-2-4cm phakathi kodonga lomkhusane kunye nomaleko wokugquma ugwebu ukugcina indawo yomile kwaye ingenamanzi.I-polyurethane foam ine-thermalinsulation ekhethekileyo kunye nomsebenzi ongenamanzi, kwaye inokuthintela ukuvuza kwangaphandle kodonga.

Amanzi apheleleyo B1 grade yokutshiza eqinile polyurethane (PU) inkqubo yokugcina ebandayo yokugcina

Izinto ezitshiziweyo eziqinileyo zogwebu lwe-polyurethane zilula ngobunzima kwaye azinampembelelo kwisakhiwo sokuqala.I-polyurethane ye-foam etshiziweyo eqinileyo inokudityaniswa kumphezulu weemnwebu ezahlukeneyo zokuthintela amanzi ezifana nodaka, ikhonkrithi, intsimbi, irabha kunye ne-asphalt.Ukutshiza eqinile i-foampolyurethane ine-foampolyurethane esezantsi. iimfuno zomphezulu otshiziweyo, inkqubo yokwakha ihamba kancinci, isantya siyakhawuleza, kwaye ukusetyenziswa kwesakhiwo akuchaphazeleki.Lolona khetho lulungileyo lokusebenzisa umsebenzi wokudityaniswa kwamanzi kunye ne-thermal insulation of sprayed rigid foam polyurethane ukwenza inguqu yokugquma kwamanzi kunye ne-thermal kuphahla lwezakhiwo zentsimbi.
