Ukufakwa kwe-spray foam kuyisisombululo esihle kakhulu sokufakwa kwe-thermal esiqukethe izithako ezimbili eziyinhloko: ama-polyol resins kanye nohlobo oluthile lwe-isocyanate. Uma lezi zithako zihlanganiswa, ziyasabela ekwakheni i-foam ekhula futhi iqine ibe yi-polyurethane. Ama-polyurethane spray foam ayasebenziseka futhi ayasebenza kahle ngoba aqukethe amagesi aphansi okuhambisa umoya ezimbotsheni zawo, okuthuthukisa izakhiwo zawo zokufakwa kwe-thermal. Kunezinhlobo ezimbili eziyinhloko zokufakwa kwe-spray foam: evulekile nevaliwe. Uhlobo ngalunye lunezinzuzo ezihlukile kanye nezindawo zokusetshenziswa.
Yenziwe Ngani I-Spray Foam Insulation?
Uma ama-polyol nama-isocyanate exutshwa, akha i-foam, akha isakhiwo se-polymer esiqinile. Ubuningi obuphansi kanye nokuthungwa okuthambile, okuguquguqukayo kwe-open-cell spray foam kwenza kube kuhle kakhulu ekusetshenzisweni kwangaphakathi okudinga ukumuncwa komsindo. Ngakolunye uhlangothi, i-closed-cell spray foam ilukhuni futhi inzima. Ama-pores ayo avaliwe ngokuphelele, abambe igesi ngaleyo ndlela andise inani le-R, okubonisa ukufudumala okuhle kakhulu. Ama-closed-cell foam amelana nomswakama futhi asebenza kabili njengezithiyo zomoya kanye nomusi, okwenza athandwe kakhulu ezindaweni ezidinga kakhulu.
Kusetshenziswa kuphi i-Spray Foam Insulation?
Ukufakwa kwe-spray foam kusetshenziswa kabanzi ezindaweni zokuhlala, zezentengiselwano kanye nezezimboni. I-open-cell foam yaziwa ngokufakwa kwayo kwe-sound okuphumelelayo futhi ivame ukusetshenziswa ezindongeni zangaphakathi, phansi kanye nophahla. Ngenxa yobuningi bayo obukhulu kanye nokuqina kwayo, i-closed-cell foam ivame ukusetshenziselwa izindonga zangaphandle, izindlu zangaphansi, izindawo zokukhasa, kanye nezindawo zophahla.
Ifomu yokufutha eneseli elivaliwe isebenza kahle kakhulu ekufakweni kwe-attic. Le nto ayisebenzi nje kuphela njengokufakwa kwe-attic, kodwa futhi inikeza isithiyo somoya kanye nomusi, okubalulekile ukuvimbela ukunqwabelana komswakama e-attic. Ngokuvimba umoya kanye nomswakama, ifomu yokufutha eneseli elivaliwe isiza ukulawula izinga lokushisa langaphakathi, ukunciphisa izindleko zamandla kanye nokuvikela izakhi zesakhiwo ekulimaleni kwamanzi okungenzeka.
Ama-Catalyst e-Polyurethane Ekusetshenzisweni Kwe-Spray Foam
Ama-catalyst e-polyurethane afanaI-MXC-BDMA(N,N-dimethylbenzylamine) kanyeI-MXC-TMAzibalulekile ekukhiqizweni kokufakwa kwe-spray foam insulation. I-MXC-BDMA ithuthukisa ukugeleza kanye nesakhiwo samaseli e-foam, ikhuthaza ukusatshalaliswa okulinganayo kanye nokunamathela okuhle kakhulu kuma-substrates. Lesi sikhuthazi sisetshenziswa kabanzi kwi-rigid polyurethane foam, siqinisekisa ukuthi i-foam iyelapheka ngamandla afanele kanye nokuqina. I-MXC-TMA, i-tertiary amine catalyst, yenzelwe izinhlelo zokusebenza ezidinga ukusabela kwe-polyisocyanurate okulawulwayo, njenge-rigid foam esetshenziswa kumashidi kanye ne-insulation yemishini efana neziqandisi. Isiza ekuqineni kwe-back-end okubushelelezi, ukuqinisekisa ukuqina nokusebenza ngokuhamba kwesikhathi.
Ukufakwa kwe-spray foam kuyaqhubeka nokuba yisisombululo esithandwayo ngenxa yokuzivumelanisa nezimo kwayo, amanani aphezulu okufakwa kwe-insulation, kanye nezakhiwo zokuvikela. Ngama-catalyst afanele, ukusetshenziswa kwe-polyurethane foam kuhlangabezana nezidingo zokusebenza eziqinile ezindaweni ezahlukene zokwakha.
