Kuchinja kwetekinoroji yemushonga weHFO uye maitiro ekuchengetedza nharaunda
Zvichienderana nemutemo wepasi rose wekuchengetedza nharaunda, hydrofluoroolefins (HFOs), sechizvarwa chechina chemishonga inofema furo, iri kukurumidza kutsiva mishonga inofema furo yeHCFC neHFC. Nekukwanisa kwayo kudziya kwepasi rose kwakaderera (GWP<1) uye kusaita ozone depletion characteristics (ODP=0), HFO foaming system yave nzira huru yehunyanzvi yeindasitiri yepolyurethane kuti ibudirire. Sekureva kwetsvagurudzo yemusika yazvino, panosvika 2026, chikamu chemusika cheHFO mumishonga inofema furo yepolyurethane chinotarisirwa kukura kusvika 58%, nekukura kwegore negore kwe12.3%.
Mabhenefiti makuru ehunyanzvi hweHFO furo system
1. Kubudirira mukushanda kwezvakatipoteredza
- Kukosha kweGWP <10: pasi nepamusoro pe99% pane HFC-245fa (GWP=1030)
- Zero ODP: haikuvadzi ozone layer uye inosangana nezvinodiwa neMontreal Protocol
- Utsi hwakaderera hweVOC: hunosangana nezvinodiwa zvekuchengetedza zvivakwa zvakaita seLEED neBREEAM
2. Kushanda kwakanaka kwazvo kwekudzivirira kupisa
Kufambiswa kwemafuta eHFO (0.013-0.015 W/m·K) muchikamu chegasi kuri nani kupfuura kwemafuta echinyakare, izvo zvinogona kuderedza kufambiswa kwemafuta epolyurethane ne15-20%, zvichiunza mhedzisiro yakakosha yekuchengetedza simba kumafiriji, mainsulation ekuvaka nedzimwe nzvimbo.
3. Matambudziko ekugadzirisa maitiro uye mhinduro
Nekuda kwehunhu hwayo hwepanyama (senge pombi yekufashaira, kupisa kwekupfuta, nezvimwewo), maHFO blowing agents akaisa zvinodiwa zvitsva zve polyurethane formulations uye maitiro:
- Kudzora kinetics ye reaction kwakanyatsojeka kunodiwa
- Gadzirisa chiyero pakati pekuita furo nekugadzira gelling
- Kuvandudza kufanana kwechimiro chemasero
- Kuvandudza mashandiro ekubatanidza substrate
Uku ndiko kukosha kweMXC-70 catalyst yedu yakagadzirirwa zvakananga masisitimu eHFO.
Chinhu chinobatsira pakugadzira MXC-70: mubatsiri akakodzera weHFO system
Zvinhu zvikuru zvechigadzirwa
MXC-70 chinhu chinobatsira che amine chisina hwema hwakawanda chakagadzirwa kuti chigadzirise matambudziko matatu makuru eHFO furo system:
1. Kudzora maitiro akatsetseka
- Kudzora nemazvo kuenderana kweHFO vaporization uye polymer curating rate
- Dzivisa kudonha kana kutsemuka kwefuro
- Kutsauka kwakajairwa kwemukombe unokwira <5% (kuyedzwa kweASTM D7487)
2. Kushanda kwakanaka kwazvo pamusoro pekurapa
- Deredza kunamira kwepazasi uye kuvandudza chitarisiko chefuro
- Kuderedza nguva yekubvisa zvinhu ne15-25%
- Yakakodzera kupfapfaidza yakamira pamusoro nepamusoro
3. Kubatanidzwa kwe substrate kwakawedzerwa
- Kuwedzera simba rekubatana nezvinhu zvakasiyana-siyana zvakaita sesimbi, purasitiki, huni, nezvimwewo ne30-50%
- Inonyanya kukodzera kuenderera mberi kwekugadzirwa kwepaneru dzesandwich
Maitiro akajairika ekushandisa
1. Munda wekudzivirira magetsi
- Chidziviriro chemufiriji/mufiriji
- Kudzivirira kupisa kwemvura
- Midziyo yekutengeserana yefriji
2. Kuvaka chishandiso chekuchengetedza simba
- Metal sandwich panel inoenderera mberi yekugadzira mutsetse
- Kuvakwa kwefuro respray panzvimbo yacho
- Zvinhu zvinodzivirira pombi
3. Kutakurwa
- Muviri werori mufiriji
- Zvinhu zvekudzivirira mvura mugungwa
- Zvinhu zvinosanganiswa nendege
Sei uchifanira kusarudza yeduMXC-70?
1. Rutsigiro rwehunyanzvi hwehunyanzvi: Ipa mabasa akazara kubva pakuedza murabhoritari kusvika pakugadzirwa kwakawanda
2. Mhinduro dzakagadzirirwa: Gadzirisa fomura zvinoenderana nemidziyo yako uye maitiro
3. Sisitimu yekugovera yakagadzikana: Zvigadziko zviviri zvekugadzira muAsia neEurope
Wana ruzivo rwehunyanzvi uye mienzaniso
