Uguquko lobuchwepheshe be-ejenti ye-HFO foam kanye nomkhuba wokuvikela imvelo
Ngokuphikisana nesizinda semithethonqubo yezemvelo yomhlaba wonke eqinile, ama-hydrofluoroolefins (ama-HFO), njengesizukulwane sesine sama-ejenti akhipha amagwebu ngokomzimba, athatha indawo ngokushesha ama-ejenti avamile e-HCFC kanye ne-HFC akhipha amagwebu. Njengoba amandla awo okufudumala komhlaba aphansi kakhulu (GWP<1) kanye nezici zokuncipha kwe-ozone ezingenalutho (ODP=0), uhlelo lwe-HFO olukhipha amagwebu seluyindlela ebalulekile yobuchwepheshe embonini ye-polyurethane yokufeza intuthuko esimeme. Ngokusho kocwaningo lwakamuva lwemakethe, ngo-2026, isabelo semakethe se-HFO kuma-ejenti akhipha amagwebu e-polyurethane kulindeleke ukuthi sikhule sifike ku-58%, ngesilinganiso sokukhula sonyaka esihlanganisiwe esingu-12.3%.
Izinzuzo zobuchwepheshe eziyinhloko zesistimu ye-HFO foam
1. Intuthuko ekusebenzeni kwemvelo
- Inani le-GWP <10: lingaphansi kuka-99% kune-HFC-245fa (GWP=1030)
- I-ODP engenalo u-Zero: ayilimazi ungqimba lwe-ozone futhi ihlangabezana nezidingo ze-Montreal Protocol
- Ukukhishwa kwe-VOC okuphansi: kuhlangabezana nezindinganiso zesitifiketi sesakhiwo esiluhlaza njenge-LEED ne-BREEAM
2. Ukusebenza kahle kakhulu kokuvikela
Ukuqhuba kokushisa kwesigaba segesi kwe-HFO foaming agent (0.013-0.015 W/m·K) kungcono kakhulu kunokusebenza kwe-foaming agents yendabuko, okunganciphisa ukuqhubela kokushisa okuphelele kwe-polyurethane foam ngo-15-20%, okulethe imiphumela ebalulekile yokonga amandla eziqandisini, ekushiseni kwesakhiwo nakwezinye izinkambu.
3. Izinselele kanye nezixazululo zokuzivumelanisa nezimo kwenqubo
Ngenxa yezakhiwo zayo ezikhethekile zomzimba (njengephuzu lokubilisa, ukushisa komoya, njll.), ama-HFO blowing agents abeka phambili izidingo ezintsha ze-polyurethane formulations kanye nezinqubo:
- Kudingeka ukulawulwa kwe-reaction kinetic okunembe kakhudlwana
- Lungiselela ibhalansi phakathi kokwenza i-foam kanye ne-gelling
- Thuthukisa ukufana kwesakhiwo seseli
- Thuthukisa ukusebenza kokubopha kwe-substrate
Leli inani le-catalyst yethu ye-MXC-70 eyenzelwe ngqo izinhlelo ze-HFO.
Isikhuthazi se-MXC-70: umlingani ophelele wesistimu ye-HFO
Izici eziyinhloko zomkhiqizo
I-MXC-70 iyisikhuthazi se-amine esinephunga eliphansi esakhelwe ngokukhethekile ukuxazulula ngokuphelele izinselele ezintathu eziyinhloko zesistimu ye-HFO foam:
1. Ukulawula ijika lokusabela okubushelelezi
- Lawula ngokunembile ukufana kwe-vaporization ye-HFO kanye nesilinganiso sokwelapha i-polymer
- Gwema ukuqhekeka noma ukuqhekeka kwegwebu
- Ukuphambuka okujwayelekile kwejika elikhuphukayo <5% (ukuhlolwa kwe-ASTM D7487)
2. Ukusebenza okuhle kakhulu kokuphulukisa ubuso
- Nciphisa ukunamathela kobuso futhi uthuthukise ukubukeka kwegwebu
- Nciphisa isikhathi sokususa i-demoulding ngo-15-25%
- Kufanelekela ukufutha okuqondile nokungaphezulu
3. Ukunamathela okuthuthukisiwe kwe-substrate
- Amandla okubopha akhuphukile ngezinto ezahlukahlukene ezifana nensimbi, ipulasitiki, ukhuni, njll. ngo-30-50%
- Ifaneleka kakhulu umugqa wokukhiqiza oqhubekayo wamaphaneli esandwich
Izimo ezijwayelekile zohlelo lokusebenza
1. Insimu yokushisa kagesi
- Isendlalelo sokuvikela isiqandisi/ifriji
- Ukufakwa kwe-heater yamanzi
- Imishini yokuqandisa yezentengiselwano
2. Ukwakha uhlelo lokusebenza lokonga amandla
- Iphaneli yesangweji yensimbi umugqa wokukhiqiza oqhubekayo
- Ukwakhiwa kwefoam yokufutha endaweni
- Izinto zokuvimbela amapayipi
3. Ezokuthutha
- Umzimba weloli eliqandisiwe
- Izinto zokuvikela zasemanzini
- Izinto ezihlanganisiwe zezindiza
Kungani ukhethe eyethuI-MXC-70?
1. Usekelo lobuchwepheshe lochwepheshe: Nikeza izinsizakalo zenqubo ephelele kusukela ekuhlolweni kwelabhorethri kuya ekukhiqizweni okukhulu
2. Izixazululo ezenziwe ngokwezifiso: Lungisa ifomula ngokuya ngemishini yakho kanye nenqubo
3. Uhlelo lokuhlinzeka oluzinzile: Izisekelo zokukhiqiza ezimbili e-Asia naseYurophu
