Maitiro Ekuvandudza HFOs Dzine Hushamwari Nezvakatipoteredza uye Advanced Catalyst Solutions

Sezvo zvinangwa zvemamiriro ekunze pasi rose zviri kuteverwa nekukurumidza, indasitiri yepolyurethane iri kuchinja zvikuru. Kuchinja kubva pazvinhu zvechinyakare zvekuputira kuenda kune zvisina njodzi kunharaunda HFOs isingakuvadzi zvakatipoteredza(Hydrofluoroolefins)rave kuvandudzwa kwetekinoroji kwakakosha kwezvinhu zvinodzivirira kupisa, furo repolyurethane rakapfapfaidzwa (SPF), furo rakagadzika, kuputira midziyo yepamba, uye mashandisirwo emotokari. Panguva imwe chete, kuwedzera kuri kuramba kuchienderera mberi kwekudiwa kwezvinokonzeresa HFO zvinoshanda zvakanyanya kuri kukurudzira vagadziri kuti vashandise mhinduro dzakachena, dzinoshanda zviri nani, uye dzakagadzikana dzekugadzirisa matambudziko.

1. Nei HFOs dziri kuva Muyero Wepasi Rose

1.1 Kubva kuCFC kuenda kuHFO: Chizvarwa Chechina ChemaBlowing Agents

Kushanduka kwezvinhu zvinoputira kunotevera nzira yakajeka yekutonga uye yezvakatipoteredza:

2. Mabhenefiti Akakosha Ekuchengetedza HFOs Zvisina Kukuvara

✔ GWP yakaderera zvakanyanya (<1) – 99.9% kuderedzwa zvichienzaniswa neHFCs

HFO dzakadai seHFO-1234yf, HFO-1233zduyeHFO-1234zekuora nekukurumidza mumhepo nehupenyu hwese hwemazuva kusvika kumavhiki, zvichideredza zvakanyanya kukanganiswa kwemamiriro ekunze.

✔ Zero ODP - Hapana kukuvadza ozone layer

✔ Kudzivirira kupisa kwakanyanya uye kushanda zvakanaka kwesimba

Furo reHFO rinoratidza kufambiswa kwemafuta zviri nani uye kugadzikana kwakakwirira, zvichiita kuti rive rakakodzera:

• Midziyo yemufiriji
• Mapaneru ekudzivirira zvivakwa & mapaneru esandwich
• Furo repurasitiki rinopfapfaidzwa (SPF)

✔ Kuyerera kwakanyanya uye chimiro chemasero chakapfava

Hunhu hwemuviri hweHFO hunodamacatalyst ane reactivity yakagadziriswa, kunyanya pakuenzanisa kukwira, kuyerera, uye kupora kwefuro.

3. Mashandisirwo Anoitwa HFOs muIndasitiri yePolyurethane

3.1 Kugamuchirwa Nokukurumidza Muzvikamu Zvikuru

Kuchinja uku nekukurumidza kunoita kuti pave nekudiwa kukuru kweZvishandiso zve polyurethane zvakagadziriswa neHFO.

4. Matambudziko eCatalyst muHFO Systems

Kuchinja kuita ma "HFO blowing agents" kunochinja zvakanyanya mashandiro emakemikari ePU reactions:

Mafomula eHFO anowanzo kuve ne:

• Kuderedza reactivity yekutanga
• Kusiyana kwakanyanya kwekunyunguduka
• Maitiro matsva echimiro chefuro
• Zvinodiwa zvakanyanya pakugadzirisa pamusoro
• Viscosity yakakwira mu pre-mixes

Saka, vagadziri vemafuro vanofanira kushandisazvinhu zvakakosha zveHFOizvo zvinopa:

✔ Kuenzanisa kwakasimba pakati pezvinhu zvepamberi nepamberi

Kutsiva kuderedzwa kwekutanga kweHFO reaction.

✔ Kuyerera kwemvura kuri nani

Zvakakosha zvikuru kumapaneru ePIR, SPF, uye mitsetse yekugadzira inoenderera mberi.

✔ Kurapa kwepamusoro nekukurumidza

Kudzivirira kuderera kwemasero uye kuparara kwawo.

✔ Kunhuhwirira kushoma uye kusvibiswa kushoma

Kusangana nemitemo yepasi rose yezvakatipoteredza.

5. Mhinduro dzeAdvanced Catalyst dzeHFO Systems

Semugadziri we polyurethane catalyst ane hunyanzvi, tinopa portfolio yakazara yakagadzirirwa zvakanangaHFOs isingakuvadzi zvakatipoteredza.

Zvinokurudzira HFO-Optimized Catalysts

• MXC-B20：Kunonoka kwakanaka kwazvo pamberi pechiso, mushonga wakasimba wekumashure, wakanakira HFO SPF
• MXC-R40: Inovandudza kuporeswa kwemvura pamusoro, yakakodzera masisitimu ekushandisa mvura pamwe chete neHFO

Izvi zvinogadzirisa matambudziko akajairika ekugadzira HFO, akadai se:

• Kutanga zvishoma nezvishoma
• Kukwira kweprofile kusina kuenzana
• Kusagadzikana kwemasero
• Kuomarara mushure mekupora

6. Maonero Emafambiro Emusika: HFO + Kubatanidzwa kweCatalyst Kuchatonga Makore Gumi Anotevera

6.1 Kudiwa kweHFO pasi rose kuri kukura ne>10% pagore

Zvinokurudzirwa nekuvaka kusingashandise simba zvakanyanya, kuisa magetsi mumotokari, uye kuwedzera kwemagetsi anotonhorera.

6.2 Masisitimu eCatalyst anofanirwa kushanduka panguva imwe chete

MaHFO haagone kusvika pakushanda zvakanaka pasina macatalyst akagadzirirwa makemikoro avo.

6.3 Zvinhu zvinokonzeresa kunhuhwirira kushoma, uye zvine VOC shoma zvichave zvakanyanya

Mitemo yezvakatipoteredza (EPA, EU F-Gas, zvinangwa zveChina zvekushandisa kabhoni mbiri) iri kukurumidzisa maitiro aya.

Mapaneru ekudzivirira ePIR ane HFO-based PIR anokura nekukurumidza

Kunyanya mu:

• Zvivako zvekare
• Kuchengetera zvinhu zvinotonhora
• Kuvaka kwakafanana
• Denga remaindasitiri

7. Mhedziso: HFO neCatalyst Innovation Zvichatsanangura Remangwana rePolyurethane

Kuchinja kwenyika yose kuenda kuHFOs isingakuvadzi zvakatipoteredzainomiririra mukana wenhoroondo kuindasitiri yepolyurethane. Sezvo maHFC ari kubviswa uye mitemo ichisimbiswa, vagadziri vanofanirwa kushandisa mashandiro epamusoroHFO catalystskuti pave nekuenzana kwemaitiro, kushanda zvakanaka, uye kugarika.

Mhinduro dzedu dze catalyst—kusanganisiraMXC-B20,MXC-TMA, MXC-10, nedzimwe—dzakagadzirwa kuti dzibatsire vagadziri vepolyurethane kuchinja zvakanaka kupinda munguva yeHFO, zvichipa:

• Kubudirira kwepamusoro kwekudzivirira kupisa
• Kugadzirwa kwakachena uye kwakasvibira
• Kugadziriswa kwakagadzikana mune furo rakasimba uye rakapfapfaidzwa
• Kutevedzera mitemo yepasi rose yezvakatipoteredza

Nekubatanidza zvemhando yepamusoroHFO inofemera zvinhuyakagadziriswazvinokonzeresa polyurethane, indasitiri iyi ichaita zvese zviri zviviri kushanda zvakanaka uye kuderedza kabhoni zvine revo—zvichitsigira remangwana rinogara kwenguva refu uye risingashandise simba zvakanyanya.
