Uguquko lwetekhnoloji yearhente ye-HFO ekhupha amagwebu kunye nomkhwa wokukhusela okusingqongileyo
Ngokuchasene nemvelaphi yemithetho engqongqo yokusingqongileyo yehlabathi, ii-hydrofluoroolefins (ii-HFO), njengesizukulwana sesine see-agents ezikhupha igwebu, zithatha indawo ngokukhawuleza kwii-agents zemveli ze-HCFC kunye ne-HFC foam. Ngenxa ye-potential yayo ephantsi kakhulu yokufudumala kwehlabathi (GWP<1) kunye neempawu zokuphelelwa yi-ozone (ODP=0), inkqubo ye-HFO foam iye yaba yindlela ebalulekileyo yobugcisa kwishishini le-polyurethane ukufezekisa uphuhliso oluzinzileyo. Ngokutsho kophando lwamva nje lwemarike, ngo-2026, isabelo semarike se-HFO kwii-agents ezikhupha igwebu ze-polyurethane kulindeleke ukuba sikhule siye kwi-58%, kunye nezinga lokukhula elidibeneyo lonyaka eliyi-12.3%.
Iingenelo zobugcisa eziphambili zenkqubo ye-HFO foam
1. Inkqubela phambili ekusebenzeni kokusingqongileyo
- Ixabiso le-GWP <10: ngaphezulu kwe-99% ngaphantsi kune-HFC-245fa (GWP=1030)
- Akukho ODP: ayonakalisi umaleko we-ozone kwaye iyahlangabezana neemfuno zeMontreal Protocol
- Ukukhutshwa kwe-VOC ephantsi: ihlangabezana nemigangatho yesiqinisekiso sezakhiwo eziluhlaza ezifana ne-LEED kunye ne-BREEAM
2. Ukusebenza kakuhle kokukhusela ubushushu
Ukuqhuba kobushushu besigaba segesi kwi-HFO foaming agent (0.013-0.015 W/m·K) kungcono kakhulu kune-arhente zemveli zokuqhuba ubushushu, nto leyo enokunciphisa ukuqhubela kobushushu be-polyurethane foam nge-15-20%, nto leyo ebangela ukuba kubekho iziphumo ezibalaseleyo zokonga amandla kwiifriji, kwi-insulation yesakhiwo nakwezinye iindawo.
3. Imingeni kunye nezisombululo zokuziqhelanisa neenkqubo
Ngenxa yeempawu zayo ezikhethekileyo zomzimba (ezifana nendawo yokubilisa, ubushushu bokufuma, njl.njl.), ii-HFO blowing agents zibeka phambili iimfuno ezintsha ze-polyurethane formulations kunye neenkqubo:
- Ulawulo oluchanekileyo ngakumbi lwe-reaction kinetics luyafuneka
- Lungiselela ibhalansi phakathi kokwenza i-foam kunye ne-gelling
- Ukuphucula ukufana kwesakhiwo seseli
- Ukuphucula ukusebenza kokubopha i-substrate
Eli lixabiso le-catalyst yethu ye-MXC-70 eyenzelwe ngokukodwa iinkqubo ze-HFO.

Iimpawu eziphambili zemveliso
I-MXC-70 sisincedisi se-amine esingenavumba liphantsi esenzelwe ngokukodwa ukusombulula ngokugqibeleleyo imingeni emithathu ephambili yenkqubo ye-HFO foam:
1. Ulawulo lwejika lokuphendula oluthambileyo
- Lawula ngokuchanekileyo ukuhambelana kwe-HFO vaporization kunye ne-polymer coating rate
- Kuphephe ukuqhekeka okanye ukuqhekeka kwegwebu
- Ukuphambuka okuqhelekileyo kwegophe elinyukayo <5% (uvavanyo lwe-ASTM D7487)
2. Ukusebenza kakuhle kokunyanga umphezulu
- Nciphisa ukunamathela komphezulu kwaye uphucule ukubonakala kwefoam
- Nciphisa ixesha lokunciphisa isantya nge-15-25%
- Ifanelekile ukutshiza ngokuthe nkqo nangaphezulu komphezulu
3. Ukunamathela okuphuculweyo kwe-substrate
- Ukomelela kokubopha ngezinto ezahlukeneyo ezifana nesinyithi, iplastiki, umthi, njl. nge-30-50%
- Ifanelekile ngokukodwa kumgca wemveliso oqhubekayo weepaneli zesandwich
