Iinkqubo ze-HFO Foam: Isisombululo esinobuhlobo nokusingqongileyo sePolyurethane Foams

IiHydrofluoroolefins (iiHFO) zimele isizukulwana esitsha seearhente zokuvuthela ezinobuhlobo nokusingqongileyo ezisetyenziswa kwi-polyurethane foams. Njengoko ingqwalasela yehlabathi ikhula ekunciphiseni impembelelo yokusingqongileyo, iiHFO ziba lukhetho olukhethwayo kwiintlobo ngeentlobo zezicelo, zithatha indawo yeehydrofluorocarbons ezindala (iiHFC) ngenxa yeprofayili yazo entle yokusingqongileyo.

Yintoni i-HFO?

Ii-HFO ziludidi lweekhompawundi ezisetyenziswa kakhulu njengeefriji, ii-blowing agents, ii-propellants, kunye nezinyibilikisi. Kwiinkqubo ze-polyurethane foaming, ii-HFO zisebenza njengee-blowing agents ezinceda ekudaleni ulwakhiwo lweseli lwee-foams, zinegalelo kwiimpawu zazo zokuthintela ukugquma, ukuqina, kunye nokuzinza.

Ii-HFO zifumene udumo njengoko ii-HFC zisuswa ngokwemiqathango yemigaqo yehlabathi ejolise ekunciphiseni izinto ezine-global warming potential ephezulu (GWP). Ngelixa ii-HFC, ezifana ne-HFC-245fa, zazisetyenziswa kakhulu kwiinkqubo ze-foam, zine-GWP ephezulu kwaye zinegalelo ekuncipheni kwe-ozone. Ngokwahlukileyo koko, ii-HFO azina-ozone depletion potential (ODP) kwaye ziphantsi kakhulu amaxabiso e-GWP, nto leyo eyenza ukuba zibe yindlela ezinzileyo ngakumbi.

Iingenelo zeNkqubo zeFoaming ze-HFO

1. Impembelelo ephantsi kwiNdalo: Eyona nzuzo ibalulekileyo yee-HFO kukuba azinampembelelo ingako kwindalo esingqongileyo. Ii-HFO azina-ODP kwaye azina-GWP iphantsi kakhulu, nto leyo enegalelo ekunciphiseni ukukhutshwa kwegesi ezibangela ubushushu.
2. Ukusebenza kakuhle kwamandla: Iifoam ezisekelwe kwi-HFO zibonisa iimpawu ezibalaseleyo zokukhusela ubushushu, ziphucula ukusebenza kakuhle kwamandla kwezicelo ezifana neefriji, iifriji, ukhuseleko lwefoam yokutshiza, kunye nezixhobo zokwakha.
3. Ukhuseleko kunye nokuguquguquka kwezinto: Ii-HFO azitshi, azinabungozi, kwaye zibonelela ngokuguquguquka kwiinkqubo ezahlukeneyo zokufutha, kuquka amagwebu aqinileyo naguquguqukayo. Zifanelekile ngakumbi kwiinkqubo ezisebenzisa amanzi njengesixhobo sokufutha kunye, nto leyo enciphisa ngakumbi ukuxhomekeka kwiiarhente zekhemikhali zemveli.
4. Iipropati zeFoam eziphuculweyo: Ii-HFO zinegalelo kwisakhiwo seseli esincinci nesifanayo kwi-polyurethane foams, esinceda ekugcineni amandla oomatshini, uzinzo olulinganayo, kunye nokusebenza kwe-foam iyonke. Zikwanciphisa ukuqhekeka kwe-foam, ziphucula ukunyangwa komphezulu, kwaye zonyusa ukunamathelana phakathi kwe-substrates.

Ikamva lee-HFO kwiPolyurethane Foams

Njengoko imfuno yehlabathi jikelele yezinto ezisebenzisa umbane ngendlela ecocekileyo neyonga ukusingqongileyo iqhubeka ikhula, iinkqubo zokufaka amagwebu ezisekelwe kwi-HFO kulindeleke ukuba zibonakale ngakumbi kushishino lwe-polyurethane foam. Utshintsho oluvela kwi-HFC ukuya kwi-HFO aluhambelani nje kuphela nemigaqo yokusingqongileyo kodwa lukwaqinisekisa ukuba abavelisi banokuqhubeka nokuvelisa amagwebu asebenza kakuhle ngempembelelo encinci kokusingqongileyo.

Kwinkampani yethu, sizimisele ukuphucula iteknoloji ye-polyurethane catalyst ukuxhasa iinkqubo ze-HFO foam.Isincedisi seMXC-70, eyenzelwe ngokukodwa ukusetyenziswa kwiinkqubo ezisekwe kwi-HFO, iphucula ukunyangwa komphezulu, ikhuthaza ukunyuka okuthe tye, kwaye iphucula ukunamathelana kwe-substrate. Ikwafaneleka ngakumbi kwiinkqubo ezisebenzisa amanzi njenge-arhente yokuvuthela kunye, ibonelela ngokuguquguquka kunye nokukhutshwa okuphantsi kokukhutshwa kwegesi kwizicelo ze-foam eziguquguqukayo neziqinileyo.
