incazelo emfushane:

Imininingwane Yomkhiqizo

Ukwakhiwa komkhiqizo

Igwebu eliqinile elifuthwe nge-polyurethane liwubufakazi bamanzi, obulondoloza ukushisa kanye negwebu elivikela ukushisa elakhiwe ngokuxuba izingxenye A no-B ngesilinganiso esithile futhi lenze uchungechunge lokusabela kwamakhemikhali.

▲Ingxenye ebalulekile

I-A component material yenziwe nge-polyol (i-polyether ehlanganisiwe noma i-polyester) namanzi, i-catalyst, i-stabilizer, i-flame retardant nezinye izithasiselo, ngokuvamile ezaziwa ngokuthi impahla emhlophe.

▲B ingxenye ebalulekile

Ingxenye eyinhloko ye-B-component i-isocyanate, okuwuketshezi olunsundu, oluvame ukwaziwa ngokuthi izinto ezimnyama.

Amanzi agcwele Ibanga le-B1 lokufafaza i-polyurethane eqinile (i-PU) yokufaka isitoreji esibandayo

Ukufafaza i-foam eqinile i-polyurethane isekelwe ku-onisocyanate (inhlamba emnyama) kanye nama-polyols (eyaziwa ngokujwayelekile njenge-materiallj emhlophe exutshwe nama-catalysts, ama-modifiers, ama-anti-aging agents.I-phosphorus nitrogen flame retardants (ucwaningo oluzimele nokwehliswa), amanzi (ucwaningo oluzimele nokuthuthukiswa) nezinye izithasiselo (okuvame ukwaziwa ngokuthi izinto ezimhlophe).Ukuxuba okufanayo. ukufutha ngomfutho ophezulu, kanye ne-sitefoaming kwenza uhlobo olusha lwe-polymerthermal insulation ephezulu ye-molecular kanye nezinto ezingangeni manzi. inokusebenza okuhle kakhulu kokufakwa kwe-thermal kanye nokusebenza kahle kokuvikela amanzi.Ukusebenza kokushisa okushisayo kungcono kunokushisa igwebu lendabuko eliqinile elijwayelekile, alilona i-fluorine, alinabuthi futhi alingcolisi igwebu langempela le-B1 polyurethane eliqinile.

Iphaneli yesangweji ye-polyurethane (PUR) uhlelo lokufakwa kwesitoreji esibandayo

Futha uhlelo oludidiyelwe lokufulela nge-polyurethane lokonga amandla, ukonga ukushisa nokuvikela amanzi

Amapaneli aseseji le-polyurethane (i-PUR) asebenzisa amaphaneli e-foampolyurethane aqinile (noma i-polyurethane eguquliwe) njengezinto zokushisa ezishisayo. Amaphaneli aqiniswa ngokwemvelo futhi ahlanganiswe ukuze izinga lawo lokuvutha lifinyelele izinga le-compositeA, kuyilapho ezuza izakhiwo ezinhle kakhulu zegwebu le-polyurethane., Isilinganiso somlilo sivelele kakhulu., futhi ububanzi bokusebenza babanzi.

Ukufakwa kwe-flat ophahleni ezakhiweni ezintsha nezikhona kungenye yezindawo eziyinhloko zokusebenzisa i-foam e-rigidpolyurethane efafaziwe.

Ukuzijwayeza kufakazele ukuthi ukufutha igwebu eliqinile le-polyurethane ukushisa uphahla kungonga u-80% wesikhathi kanye no-50% wezindleko zokutshala imali uma kuqhathaniswa nezindlela ezijwayelekile zokuvikela ukushisa. Ikakhulukazi kulezo zindawo ezibalulekile kanye nezindawo zedome noma izindawo okungelula ukuphatha Udonga lwe-parapet, ukufafaza kungenziwa kalula. Ukufafaza i-foam eqinile ye-polyurethane kungelapheka ngokushesha futhi kungahamba phezu kwayo ngemva kwemizuzu engamashumi amabili.Ungakhetha ukusebenzisa ngokuqondile ungqimba oluncane oluvikelayo lwefilimu olungamelana nemisebe ye-ultraviolet ebusweni begwebu lesifutho.

Ukufafaza i-foam eqinile ye-polyurethane kungafuthwa kalula futhi ngokushesha ophahleni olomile nolungenalo uthuli.

Futha i-polyurethane yangaphandle yokonga amandla odongeni, ukulondolozwa kokushisa kanye nesistimu ehlanganisiwe yokungena kwamanzi

Izinzuzo zokufafaza i-foam eqinile ye-polyurethane yokufaka udonga lwangaphandle:

1.Ukusebenza okuhle kokugcinwa kokushisa kanye ne-conductivity ephansi yokushisa

2.Ukuzinza okuphezulu kwe-dimensional, akukho ukugoba, akukho ukulwa, akukho ukuguquguquka

3.Impilo ende yesevisi (impilo yesevisi efanayo nesakhiwo ingasetshenziswa)4.Ukwakhiwa okulula, ukusebenza okubanzi kanye nesikhathi sokwakha esifushane

5.Amandla okubopha aqinile, ukuhlanganisa okubalulekile, akukho umgodi, akukho ukuqhekeka futhi akukho ukuwa

6. Ukusebenza okuhle okungangeni manzi, isakhiwo seseli evaliwe ngokuphelele

7.Non-fluorine, non-toxic futhi engangcolisi

8.Ukusebenza okuphezulu kwe-flame retardant, izinto zangempela zebanga le-B1

Udonga lwamakhethini omile olulengayo olusindisa amandla lwangaphandle

Uhlelo lwangaphandle lwe-thermal insulation system ngemuva kodonga lwamakhethini noma i-dry-hanging yangaphandle ye-thermal insulation system yodonga lwamakhethini ingasetshenziselwa ukulungiswa kwezakhiwo ezintsha nezakhiwo ezikhona.I-metal orstone surface layer yesistimu yamakhethini eyomile elengayo ingavikela izingxenye zangaphandle zodonga esimweni sezulu, futhi ingasetshenziswa njenge-facade yesakhiwo sokuhlobisa ukunikeza abaklami ukukhetha okwengeziwe.

Okokuqala lungisa izingxenye ezishumekiwe zesistimu yodonga lwamakhethini odongeni, bese ufafaza i-foam eqinile ye-polyurethaneazungeze udonga kanye nezingxenye ezishunyekiwe.Ngokohlobo lodonga lwamakhethini olomile olulengayo, i-keel eqondile noma i-aluminurguide rail ingafakwa ukulungisa nokufaka udonga lwamakhethini.Gcina ungqimba wokungenisa umoya ongu-2-4cm phakathi kodonga lwekhethini kanye nongqimba olufaka igwebu ukuze ugcine indawo yomile futhi ingenawo umswakama.I-polyurethane foam inomsebenzi oyingqayizivele we-thermalinsulation kanye nomsebenzi ongenawo amanzi, futhi ingavimbela ukuvuza kwangaphandle kodonga.

Amanzi agcwele Ibanga le-B1 lokufafaza i-polyurethane eqinile (i-PU) yokufaka isitoreji esibandayo

I-foam eqinile ye-polyurethane impahla efuthwe ilula ngesisindo futhi ayinamthelela esakhiweni sokuqala.I-foam polyurethane efuthwe eqinile eqinile ingahlanganiswa nolwelwesi oluvikela amanzi oluhlukahlukene njengodaka, ukhonkolo, insimbi, irabha kanye ne-asphalt.Ukufutha i-foampolyurethane eqinile ine-foampolyurethane ephansi izidingo zendawo efuthwe, inqubo yokwakha ihamba kancane, isivinini siyashesha, futhi ukusetshenziswa kwesakhiwo akuthinteki.Kuyisinqumo esingcono kakhulu sokusebenzisa umsebenzi wokuhlanganisa ukuvikela ukungena kwamanzi kanye nokushisa okufafaziwe okuqinile kwegwebu le-polyurethane ukwenza uguquko lwe-insulation olungangeni manzi nokushisa ophahleni lwezakhiwo zensimbi.
