Iindlela zoPhuhliso lwee-HFO ezinobuhlobo nokusingqongileyo kunye nezisombululo ze-Advanced Catalyst

Njengoko iinjongo zemozulu zehlabathi zifezekiswa ngesantya esiphezulu, ishishini le-polyurethane litshintsha kakhulu. Utshintsho oluvela kwii-agents zemveli zokuvuthela ukuya kwi-okusingqongileyo olunobuhlobo nokusingqongileyo ii-HFO ezinobuhlobo nokusingqongileyo(IiHydrofluoroolefins)iye yaba luphuculo olubalulekileyo lobuchwepheshe kwizinto zokukhusela ubushushu, i-sprayed polyurethane foam (SPF), i-rigid foam, i-insulation yezixhobo zasekhaya, kunye nokusetyenziswa kweemoto. Kwangaxeshanye, ukukhula okuqhubekayo kwemfuno ye-iikhatalyst ze-HFO ezisebenza kakuhle ikhuthaza abavelisi ukuba basebenzise izisombululo ze-catalyst ezicocekileyo, ezisebenzayo nezizinzileyo.

1. Kutheni ii-HFOs Zisiba Yimigangatho yeHlabathi

1.1 Ukusuka kwi-CFC ukuya kwi-HFO: Isizukulwana Sesine See-Blowing Agents

Uphuhliso lwee-air agents lulandela indlela ecacileyo yokulawula kunye nokusingqongileyo:

2. Iingenelo eziphambili ze-HFO ezinobuhlobo nokusingqongileyo

✔ I-GWP ephantsi kakhulu (<1) – ukwehla ngama-99.9% xa kuthelekiswa nee-HFC

Ii-HFO ezifanaI-HFO-1234yf, I-HFO-1233zdkunyeI-HFO-1234zeziwohloka ngokukhawuleza emoyeni ngobomi bodwaiintsuku ukuya kwiiveki, ukunciphisa kakhulu impembelelo yemozulu.

✔ Akukho ODP – Akukho monakalo kwi-ozone layer

✔ Ubushushu obuphezulu kunye nokusebenza kakuhle kwamandla

Ifoam ye-HFO ibonisa ukuhanjiswa kobushushu okungcono kunye nozinzo oluphezulu, nto leyo eyenza ukuba ilungele:

• Izixhobo zefriji
• Iiphaneli zokwambathisa izakhiwo kunye neephaneli zesandwich
• I-spray polyurethane foam (SPF)

✔ Ukuchaneka okuphezulu kunye nokwakheka kweeseli okucolekileyo

Iimpawu zomzimba ze-HFO zifunaiikhatalyst ezine-reactivity ephuculweyo, ingakumbi ukulinganisela ukunyuka kwefoam, ukuhamba kwayo, kunye nokunyanga.

3. Indlela ii-HFO eziguqula ngayo ishishini lePolyurethane

3.1 Ukwamkelwa Okukhawulezileyo Kumacandelo Aphambili

Olu tshintsho lukhawulezayo ludala imfuneko engxamisekileyoIikhatalyst ze-polyurethane ezenziwe ngcono nge-HFO.

4. Imingeni yeCatalyst kwiiNkqubo ze-HFO

Ukutshintshela kwii-HFO blowing agents kutshintsha kakhulu amandla eekhemikhali eempendulo ze-PU:

Iifomyula ze-HFO zihlala zine:

• Ukusebenza okuphantsi kokuqala
• Umahluko ophezulu wokunyibilika
• Ukuziphatha okutsha kwemofoam
• Iimfuneko ezingqongqo zokunyanga umphezulu
• I-viscosity ephezulu kwi-pre-mixes

Ke ngoko, abavelisi befoam kufuneka basebenziseiikhatalyst ezikhethekileyo ze-HFOezibonelela:

✔ Ibhalansi eyomeleleyo phakathi kwe-front-end

Ukubuyisela ukuqaliswa kokusabela kwe-HFO okunciphileyo.

✔ Ukuphucula ukugeleza kwamanzi

Kubaluleke ngakumbi kwiiphaneli ze-PIR, i-SPF, kunye nemigca yemveliso eqhubekayo.

✔ Ukulungiswa komphezulu ngokukhawuleza

Ukuthintela ukushwabana nokuwa kweeseli.

✔ Ivumba eliphantsi kunye nokukhutshwa komoya okuphantsi

Ukuhlangabezana nemigaqo yamazwe ngamazwe yokusingqongileyo.

5. Izisombululo zeCatalyst eziPhambili zeeNkqubo ze-HFO

Njengomvelisi we-polyurethane catalyst oqeqeshiweyo, sinikezela ngepotifoliyo epheleleyo eyenzelwe ngokukodwaii-HFO ezinobuhlobo nokusingqongileyo.

IiCatalysts eziCetyisiweyo ze-HFO

• I-MXC-B20：Ukulibaziseka okugqwesileyo kwe-front-end, unyango oluqinileyo lwe-back-end, ilungele i-HFO SPF
• I-MXC-R40: Iphucula ukunyangwa komphezulu, ilungele iinkqubo zokuvuthela amanzi kunye ne-HFO

Ezi catalysts zijongana nemingeni eqhelekileyo yokwenziwa kwe-HFO, efana nale:

• Ukuqalisa kancinci
• Iprofayili yokunyuka okungalinganiyo
• Ukungazinzi kweeseli
• Ukubuthathaka emva kokunyanga

6. Imbonakalo yeNdlela yeMarike: Ukuhlanganiswa kwe-HFO + Catalyst kuya kulawula iminyaka elishumi ezayo

6.1 Imfuno ye-HFO yehlabathi ikhula nge->10% ngonyaka
