Kacaanka tignoolajiyada wakiilka xumbo HFO iyo isbeddelka ilaalinta deegaanka
Iyada oo laga duulayo asalka xeerarka deegaanka ee caalamiga ah ee sii kordhaya, hydrofluoroolefins (HFOs), oo ah jiilka afraad ee wakiilada xumbo-samaynta jirka, ayaa si degdeg ah u beddelaya wakiilada xumbo-samaynta dhaqameed ee HCFC iyo HFC. Iyada oo leh awooddeeda aadka u hooseysa ee kulaylka caalamiga ah (GWP<1) iyo astaamaha dhimista ozone eber (ODP=0), nidaamka xumbo-samaynta HFO wuxuu noqday waddo farsamo oo muhiim u ah warshadaha polyurethane si loo gaaro horumar waara. Sida laga soo xigtay cilmi-baaristii ugu dambeysay ee suuqa, marka la gaaro 2026, saamiga suuqa ee HFO ee wakiilada xumbo-samaynta polyurethane ayaa la filayaa inuu koro ilaa 58%, iyadoo heerka kobaca sanadlaha ah uu yahay 12.3%.
Faa'iidooyinka farsamo ee asaasiga ah ee nidaamka xumbo HFO
1. Horumar laga sameeyay waxqabadka deegaanka
- Qiimaha GWP <10: in ka badan 99% ka hooseeya HFC-245fa (GWP = 1030)
- Eber ODP: ma waxyeeleyso lakabka ozone-ka waxayna buuxisaa shuruudaha Xeerka Montreal
- Qiiqa VOC ee hooseeya: wuxuu buuxiyaa heerarka shahaadada dhismaha cagaaran sida LEED iyo BREEAM
2. Waxqabadka dahaarka oo aad u fiican
Qaboojinta kulaylka wejiga gaaska ee wakiilka xumbo-samaynta HFO (0.013-0.015 W/m·K) ayaa si weyn uga wanaagsan kan wakiilada xumbo-samaynta dhaqameed, taas oo yarayn karta guud ahaan kulaylka kulaylka ee xumbo-samaynta polyurethane 15-20%, taasoo saameyn muhiim ah ku leh badbaadinta tamarta qaboojiyeyaasha, dahaarka dhismaha iyo meelaha kale.
3. Caqabadaha iyo xalalka la qabsiga habka
Iyada oo ay ugu wacan tahay sifooyinkeeda gaarka ah ee jireed (sida barta karkarinta, kulaylka uumiga, iwm.), wakiilada afuufaya HFO waxay soo bandhigeen shuruudo cusub oo loogu talagalay qaacidooyinka iyo hababka polyurethane:
- Xakamaynta kinetics-ka falcelinta oo sax ah ayaa loo baahan yahay
- Hagaaji dheelitirka u dhexeeya xumbo iyo jelling
- Hagaajinta midnimada qaab-dhismeedka unugyada
- Kordhi waxqabadka isku xidhka substrate-ka
Kani waa qiimaha kataliyaha MXC-70 ee si gaar ah loogu sameeyay nidaamyada HFO.
MXC-70 kiciyaha: lammaanaha ugu habboon ee nidaamka HFO
Astaamaha ugu muhiimsan ee badeecada
MXC-70 waa kataliye amine ah oo ur yar leh oo si gaar ah loogu talagalay inuu si fiican u xalliyo saddexda caqabadood ee asaasiga ah ee nidaamka xumbo HFO:
1. Xakamaynta qalooca falcelinta siman
- Si sax ah u xakamayso isku-dhafka uumiga HFO iyo heerka daaweynta polymer-ka
- Ka fogow burburka xumbo ama dildilaaca
- Kala leexashada caadiga ah ee qalooca kor u kacaya <5% (tijaabada ASTM D7487)
2. Waxqabadka daaweynta dusha sare ee aadka u fiican
- Yaree dhegdhegga dusha sare oo hagaaji muuqaalka xumbo
- Soo gaabi waqtiga dejinta 15-25%
- Ku habboon buufinta dusha sare iyo tan sare ee toosan
3. Adkaynta substrate-ka oo la xoojiyay
- Xoojinta isku xidhka oo la kordhiyey iyadoo la adeegsanayo walxo kala duwan sida birta, balaastikada, alwaaxa, iwm. 30-50%
- Gaar ahaan ku habboon khadka wax soo saarka joogtada ah ee looxyada sandwich-ka
Xaaladaha codsiga caadiga ah
1. Goobta dahaarka korontada
- Lakabka dahaarka qaboojiyaha/qaboojiyaha
- Dahaarka kuleyliyaha biyaha
- Qalabka qaboojinta ganacsiga
2. Dhisidda codsiga badbaadinta tamarta
- Khadka wax soo saarka joogtada ah ee guddiga sandwich birta
- Dhismaha xumbada buufinta ee goobta
- Qalabka dahaarka tuubada
3. Gaadiidka
- Jirka gaari xamuul ah oo qaboojiyaha lagu qaboojiyey
- Qalabka dahaarka badda
- Agabka isku-dhafka ah ee duulista hawada
