Ukugquma ifoam etshizwayo sisisombululo sogquma esisebenza kakuhle esiqulathe izinto ezimbini ezisisiseko: i-polyurethane kunye ne-isocyanate. Ezi zinto zimbini zigcinwa ngokwahlukeneyo kwaye azixutywanga kunye de kube lixesha lokusetyenziswa. Nje ukuba zixutywe, zifumana i-chemical reaction ebangela ukuba umxube wande kakhulu, uzalise izikhewu kunye neendawo ezingenakufikeleleka. Olu lwandiso aluphuculi nje kuphela ukugquma, kodwa lukwabonelela ngesiphumo somoya, esiphucula ukusebenza kakuhle kwamandla.
I-Polyurethane yi-polymer eguquguqukayo esisiseko se-spray foam. Ineempawu ezibalaseleyo zokuthintela ubushushu kunye nokukwazi ukwenza ama-foam aqinileyo naguquguqukayo. I-Isocyanate yikhemikhali esebenzayo esebenza ngokubambisana ne-polyurethane ukwenza isakhiwo se-foam. Ezi zinto zimbini zanda ngokukhawuleza xa zisetyenziswa ukwenza i-foam exineneyo enamathela kumphezulu kwaye inika ukhuseleko oluhle kakhulu lobushushu, ukumelana nokufuma kunye nokuqina.
Iintlobo zokufakelwa kwe-Spray Foam
Kukho iintlobo ezimbini eziphambili zokufakelwa kwe-spray foam insulation ezisetyenziswa ekwakheni nasekwenzeni:
Igwebu leSpray eliVulekileyo: Le foam inoxinano oluphantsi kwaye lukhetho oludumileyo kwiindlela zangaphakathi. Ineempawu zokuthintela isandi kunye nesantya esiphezulu sokwandiswa, nto leyo eyenza ukuba isebenze ekuzaliseni iindawo ezincinci. Ifoam yokutshiza evulekileyo ifikeleleka lula kwaye iguquguquka kunefoam yokutshiza evaliweyo.
Igwebu leSpray eliValiweyo: Ifoam yokutshiza iiseli ezivaliweyo ineempawu zoxinano oluphezulu kunye nokukhusela ubushushu obuqinileyo kwaye isetyenziswa rhoqo kwiindawo zangaphandle okanye apho kufuneka ukumelana nokufuma okuphezulu. Yenza umqobo ongangeni manzi kwaye ifanelekile ukusetyenziswa eluphahleni, kwizindlu ezingaphantsi komhlaba, nakwiindawo ezinokuba nokufuma.
Indima kaIiCatalysts zePolyurethane
Kwimveliso ye-spray foam insulation, ii-polyurethane catalysts zidlala indima ebalulekileyo ekuqhubeni i-chemical reaction phakathi kwe-polyurethane kunye ne-isocyanate. Ezi catalysts zilawula isantya kunye nomgangatho wenkqubo ye-foam, ziqinisekisa ukuba i-foam iyanda ngokuchanekileyo, iyaphiliswa ngokufanelekileyo, kwaye ifezekisa iipropati ezifunekayo, ezinje ngokuqina, ukumelana nobushushu, kunye nokunamathela.
Isihluzi sethu se-polyurethaneI-MXC-5yi-catalyst ye-foam esekelwe kwi-amine ephezulu ekhuthaza ukusabela kwe-urea (water-isocyanate) kwiintlobo ngeentlobo zezicelo ze-polyurethane foam eziqinileyo neziguquguqukayo. Yi-catalyst eqhelekileyo kushishino esetyenziswa kwiinkqubo ze-polyurethane ezisekwe kwi-MDI, enceda ukuqinisekisa ukusebenza kakuhle kwe-foam kunye nokuhambelana.
Ukusebenzisa i-polyurethane catalyst efanelekileyo, efana ne-MXC-5, kuqinisekisa ukuba i-spray foam yakho ifikelela kwi-insulation potential yayo epheleleyo ngelixa iphucula ukwanda kwe-foam, iimpawu zokuphilisa, kunye nokuqina kwesakhiwo. Nokuba wenza i-open-cell okanye i-closed-cell spray foam, ukukhetha i-catalyst efanelekileyo kubalulekile ekuhlangabezaneni nemigangatho yokusebenza kunye nokusingqongileyo.
Kutheni Ukhetha I-Catalyst Efanelekileyo?
Abavelisi befoam yokutshiza kufuneka bakhethe i-catalyst efanelekileyo ukuze bafumane i-foam insulation ehambelanayo nesemgangathweni ophezulu. I-catalyst eyenziwe kakuhle ingenza oku kulandelayo:
- Phucula ukwandiswa kwegwebu kunye namaxesha okunyanga.
- Yandisa ukunamathela kwiindawo ezahlukeneyo.
- Qinisekisa ukuba ukukhutshwa komoya kuphantsi kwaye uhlangabezana nemigangatho yolawulo.
- Inika umswakama ongcono kunye nokumelana nobushushu.
KwaMingxu Chemicals, sinikezela ngoluhlu lwee-catalysts ze-polyurethane ezisebenza kakuhle, ezifanaI-MXC-5, yenzelwe ukusetyenziswa kwefoam eqinileyo neguquguqukayo, ikunceda ukuba uphucule iinkqubo zakho zemveliso kunye nokusebenza kwemveliso.
