Izitayela Zokuthuthukiswa Kwama-HFO Anobungani Nemvelo kanye Nezixazululo Ezithuthukisiwe Ze-Catalyst

Njengoba imigomo yesimo sezulu somhlaba wonke ilandelwa ngesivinini esikhulu, imboni ye-polyurethane ibhekana nezinguquko ezinkulu. Ushintsho oluvela ezintweni ezivamile zokufutha luye kolungangcolisi imvelo. ama-HFO anobungani nemvelo(Ama-Hydrofluoroolefins)sekuwukuthuthukiswa okubalulekile kobuchwepheshe bezinto zokuvikela ukushisa, i-sprayed polyurethane foam (SPF), i-rigid foam, i-insulation yemishini yasekhaya, kanye nezinhlelo zokusebenza zezimoto. Ngesikhathi esifanayo, ukukhula okuqhubekayo kwesidingo se-ama-catalyst e-HFO asebenza kahle kakhulu kushukumisela abakhiqizi ukuthi basebenzise izixazululo ze-catalyst ezihlanzekile, ezisebenza kahle, nezizinzile.

1. Kungani Ama-HFO Eba Yindinganiso Yomhlaba Wonke

1.1 Kusukela ku-CFC kuya ku-HFO: Isizukulwane Sesine Seziqhumane Ezivunguzayo

Ukuvela kwama-ejenti aqhumayo kulandela umkhondo ocacile wokulawula kanye nowemvelo:

2. Izinzuzo Eziyinhloko Zama-HFO Avikela Imvelo

✔ I-GWP ephansi kakhulu (<1) – ukwehla okungu-99.9% uma kuqhathaniswa nama-HFC

Ama-HFO afana ne-I-HFO-1234yf, I-HFO-1233zd, futhiI-HFO-1234zeziwohloka ngokushesha emoyeni ngokuphila impilo yonke kuphelaizinsuku kuya emavikini, kunciphisa kakhulu umthelela wesimo sezulu.

✔ Akukho ODP - Akukho monakalo ongqimbeni lwe-ozone

✔ Ukushisa okuphezulu kanye nokusebenza kahle kwamandla

I-foam ye-HFO ibonisa ukuhanjiswa okungcono kokushisa kanye nokuqina okuphezulu, okwenza ifaneleke kakhulu ku:

• Izinto ezisetshenziswa esiqandisini
• Amaphaneli okushisa izakhiwo namaphaneli esandwich
• I-spray polyurethane foam (SPF)

✔ Ukugeleza okuphezulu kanye nesakhiwo seseli esincanyana

Izici zomzimba ze-HFO zidingaama-catalyst ane-reactivity elungiselelwe, ikakhulukazi ukulinganisela ukuphakama, ukugeleza, kanye nokuqina kwegwebu.

3. Indlela Ama-HFO Aguqula Ngayo Imboni Ye-Polyurethane

3.1 Ukwamukelwa Okusheshayo Kuzo Zonke Izigaba Ezinkulu

Lolu shintsho olusheshayo ludala isidingo esiphuthumayoAma-catalyst e-polyurethane elungiselelwe kahle nge-HFO.

4. Izinselele Zokusungula Izinto Ezinhlelweni Ze-HFO

Ukushintshela kuma-ejenti okushaya i-HFO kushintsha kakhulu amandla amakhemikhali okusabela kwe-PU:

Izinhlobo ze-HFO ngokuvamile zinalokhu okulandelayo:

• Ukusabela kokuqala okuphansi
• Umehluko omkhulu wokuncibilika
• Ukuziphatha okusha kwesimo se-foam
• Izidingo eziqinile zokulungisa ubuso
• I-viscosity ephezulu kuma-pre-mixes

Ngakho-ke, abakhiqizi be-foam kumele basebenziseama-catalyst akhethekile e-HFOezihlinzeka:

✔ Ibhalansi engaphambili eqinile

Ukuze kunxeshezelwe ukwehla kokuqala kokusabela kwe-HFO.

✔ Ukugeleza okuthuthukisiwe

Kubaluleke kakhulu kumaphaneli e-PIR, i-SPF, kanye nemigqa yokukhiqiza eqhubekayo.

✔ Ukulungiswa okusheshayo kobuso

Ukuvimbela ukushwabana nokuwa kwamaseli.

✔ Iphunga eliphansi kanye nokukhishwa okuphansi komoya

Ukuhlangabezana nemithethonqubo yezemvelo yamazwe ngamazwe.

5. Izixazululo Ezithuthukisiwe Ze-Catalyst Zezinhlelo Ze-HFO

Njengomkhiqizi we-polyurethane catalyst ochwepheshe, sihlinzeka ngephothifoliyo ephelele eyenzelwe ngqoama-HFO anobungani nemvelo.

Ama-Catalyst Anconyiwe E-HFO

• I-MXC-B20：Ukubambezeleka okuhle kakhulu kwe-front-end, ukwelashwa okuqinile kwe-back-end, kulungele i-HFO SPF
• I-MXC-R40: Ithuthukisa ukwelashwa kwendawo, ilungele izinhlelo zokusebenzisa amanzi/i-HFO

Lezi zikhuthazo zibhekana nezinselele ezivamile zokwakheka kwe-HFO, njenge:

• Ukuqalisa kancane
• Iphrofayili yokuphakama okungalingani
• Ukungazinzi kweseli
• Ukuphuka ngemva kokwelashwa

6. Umbono Wendlela Yemakethe: Ukuhlanganiswa Kwe-HFO + Catalyst Kuzobusa Eshumini Elizayo Leminyaka

6.1 Isidingo se-HFO somhlaba wonke sikhula ngo->10% minyaka yonke

Kuqhutshwa ukwakhiwa okusebenzisa amandla ngendlela eyongayo, ukufakwa kukagesi ezimotweni, kanye nokwandiswa kwezintambo ezibandayo.

6.2 Izinhlelo ze-Catalyst kumele zithuthuke ngasikhathi sinye

Ama-HFO awakwazi ukufinyelela ukusebenza okuhle kakhulu ngaphandle kwama-catalyst aklanyelwe ngqo i-chemistry yawo.

6.3 Ama-catalyst anephunga eliphansi, ane-VOC encane azoba yinto evamile

Imithethonqubo yezemvelo (i-EPA, i-EU F-Gas, imigomo ye-China yokuthuthukisa i-dual-carbon) iyasheshisa lo mkhuba.

Amaphaneli okushisa e-PIR asekelwe ku-HFO angu-6.4 azokhula ngokushesha

Ikakhulukazi ku:

• Izakhiwo ezilungisiwe kusengaphambili
• Indawo yokugcina ebandayo
• Ukwakhiwa kwe-Modular
• Uphahla lwezimboni

7. Isiphetho: I-HFO kanye ne-Catalyst Innovation Kuzochaza Ikusasa le-Polyurethane

Ushintsho lomhlaba wonke oluyaama-HFO anobungani nemveloimelela ithuba eliyingqophamlando embonini ye-polyurethane. Njengoba ama-HFC eqedwa futhi imithetho iqiniswa, abakhiqizi kumele basebenzise ukusebenza okuphezuluAma-catalyst e-HFOukufeza ibhalansi yokusabela edingekayo, ukusebenza kahle, kanye nokusimama.

Izixazululo zethu ze-catalyst—kufaka phakathiI-MXC-B20,I-MXC-TMA, MXC-10, kanye nabanye—baklanyelwe ukusiza abakhiqizi be-polyurethane ukuthi bashintshele enkathini ye-HFO ngokushelela, beletha:

• Ukusebenza kahle kokuvikela okuphezulu
• Ukukhiqizwa okuhlanzekile nokuluhlaza
• Ukucutshungulwa okuzinzile kokubili ku-foam eqinile ne-spray
• Ukuhambisana nezindinganiso zemvelo zomhlaba wonke

Ngokuhlanganisa okuthuthukileAma-ejenti okushaya umoya e-HFOnge-elungiselelweama-catalyst e-polyurethane, imboni izofeza kokubili ukusebenza okuphezulu kanye nokunciphisa ikhabhoni okunenjongo—ukusekela ikusasa elizinzile nelisebenzisa kahle amandla.
