Njengoko amashishini ezama iindlela ezizinzileyo nezinobuhlobo nokusingqongileyo, utshintsho oluvela kwiiarhente zemveli zokuvuthela luye kwiIiHydrofluoroolefins (iiHFO)iye yathandwa kakhulu. Olu tshintsho lubonakala ngakumbi kwimveliso yeefoam ze-polyurethane, aphoIinkqubo ze-HFOziye zavela njengesisombululo esithembekileyo sokufezekisa ukugqwala okusebenzayo ngelixa kunciphisa impembelelo yokusingqongileyo.
Kule nqaku, siza kuhlola iingenelo zeenkqubo ze-HFO, indimaiiarhente zokuvuthelanjenge-HFO kwishishini le-polyurethane, kwaye njaniI-MXC-70, isincedisi se-amine esisebenza kakuhle kakhulu nesingenavumba liphantsi, siphucula ukusebenza kwee-polyurethane foams ezenziwe ngetekhnoloji ye-HFO.
Yintoni iNkqubo yeFoaming ye-HFO?
IiHydrofluoroolefins (iiHFO)ziluhlobo lwee-agents zokuvuthela ezisetyenziselwa ukwenza amagwebu e-polyurethane, ezaziwa ngokuba namandla awo okufudumala kwehlabathi aphantsi (GWP) xa kuthelekiswa nee-hydrofluorocarbons zemveli (ii-HFC). Ii-HFO zinegalelo ekuvelisweni kwamagwebu e-polyurethane asemgangathweni ophezulu ngelixa zijongana nemfuno ekhulayo yeendlela zokwenza izinto ezinoxanduva lokusingqongileyo. Oku kwenza iinkqubo ze-HFO zifaneleke kakhulu kumashishini agxile ekunciphiseni umngcipheko wazo kokusingqongileyo, njengokwakha, ukukhenkceza, kunye nokugquma igwebu lokutshiza.
IInkqubo yokwenza amagwebu e-HFOIsebenzisa ii-agents zokuvuthela ezisekelwe kwi-HFO ukwenza amagwebu abonisa iimpawu ezibalaseleyo zokuthintela ubushushu, ukusebenza kakuhle kwamandla, kunye nokuqina kwexesha elide. Ezi nkqubo zilungele ukuvelisa amagwebu e-polyurethane aqinileyo asetyenziswa ekuthinteleni ubushushu kwizixhobo, kwiiphaneli zokwakha, ekuthinteleni ubushushu be-spray foam, nokunye.
Ukubaluleka kwee-Agents zokuVuthela kwiMveliso yeFoam yePolyurethane
Iiarhente zokuvuthela zidlala indima ebalulekileyo ekuvelisweni kwefoam ye-polyurethane. Zinoxanduva lokwandisa ifoam nokwenza inethiwekhi yeseli, nto leyo enika ulwakhiwo lwefoam kunye neempawu zokukhusela. Iiarhente zokuvuthela zemveli ezifana nee-hydrofluorocarbons ziye zasetyenziswa kakhulu, kodwa i-GWP yazo ephezulu iye yabangela ukuphuhliswa kwezinye iindlela ezifana nee-hydrofluoroolefins.
Iiarhente zokuvuthela ezisekwe kwi-HFOzibonelela ngeenzuzo ezininzi:
I-GWP esezantsi: Ii-HFO zinempembelelo ephantsi kakhulu ekufudumaleni kwehlabathi xa kuthelekiswa nee-HFC, nto leyo eyenza zibe nobuhlobo nokusingqongileyo.
Ukuphuculwa kokugquma ubushushuIi-HFO zinegalelo ekuvelisweni kweefoam ezineempawu ezibalaseleyo zokuthintela ubushushu, nto leyo ebaluleke kakhulu kumashishini afana nokwakha kunye nokukhenkceza.
Ukuhambelana nezixhobo ezikhoyoIinkqubo ze-HFO zihlala zidityaniswa kwimigca yemveliso ekhoyo ngohlengahlengiso oluncinci, okwenza utshintsho lube lula kubavelisi.
