Theindasteri ea foam ea spraye ntse e etsa liphetoho tse kholo ho latela melaoana e mecha e reretsoeng ho fokotsa tšusumetso ea tikoloho ea lik'hemik'hale tsa indasteri. Sepheo sa bohlokoa sa melaoana ena ke ho felisoa ha li-hydrofluorocarbon tse kotsi (li-HFC) molemong oa mekhoa e meng e mosa haholoanyane tikolohong joalo ka li-hydrofluoroolefin (HFO) blowing agents. Haeba u ameha indastering ea spray foam, ho bohlokoa ho netefatsa hore li-agents tsa hau tsa foam li latela melaoana ena ho qoba likotlo le ho kenya letsoho bokamosong bo tsitsitseng haholoanyane.
Ho utloisisa Phetoho ho tloha ho HFC ho ea ho HFO
Ka 2021, United States e kentse tšebetsong melaoana e thata ea ho felisa li-HFC, lik'hemik'hale tse entsoeng ka liathomo tsa fluorine le haedrojene. Li-HFC li 'nile tsa sebelisoa haholo ho li-agent tse fokang bakeng sa likhomaretsi tsa marulelo tsa foam ea spray le thepa ea ho thibela mocheso ka lebaka la khanyetso ea tsona e ntle ea mocheso (boleng ba R). Leha ho le joalo, bokhoni ba tsona bo phahameng ba ho futhumala ha lefatše (GWP) le thepa ea tsona ea ho felisa ozone li hlahisitse matšoenyeho a tikoloho.
Li-HFC li boetse li atile haholo lits'ebetsong tsa moea o pholileng le tsa sehatsetsing, li kenya letsoho haholo ho ntšeng ha likhase tse futhumatsang lefatše. E le karolo ea boiteko bo pharaletseng ba ho fokotsa phetoho ea maemo a leholimo, liindasteri joale lia hlokahala ho fetohela ho li-HFO blowing agents. Li-HFO, kapa hydrofluoroolefins, ke moloko o mocha oa li-blowing agents tse fanang ka melemo e 'maloa ea tikoloho:
1. Ha e Chese: Li-HFO ha li chese, e leng se eketsang polokeho nakong ea ts'ebeliso le polokelo.
2. Bokgoni ba ho Fokotsa Ozone (ODP): Ho fapana le di-HFC, di-HFO ha di fokotse lera la ozone, e leng se etsang hore e be kgetho e tsitsitseng haholoanyane.
3. Bokgoni bo Tlase ba ho Futhumala ha Lefatshe (GWP): Di-HFO di na le GWP e tlase haholo ha di bapiswa le di-HFC, e leng se fokotsang tshusumetso ya tikoloho ka kakaretso.
Melemo ea Li-HFO Blowing Agents hoFoam ea Spray
Li-HFO blowing agents ke mofuta oa 'mele oa li-blowing agent tse amohelang mocheso, ho bolelang hore li monya mocheso nakong ea ts'ebetso ea ho ntša foam. Karabelo ena ea endothermic e fella ka foam e nang le sebopeho se senyenyane sa sele, e ntlafatsang ponahalo le thepa ea 'mele ea foam. Litšobotsi tsena li etsa hore li-HFO li lokele haholo lits'ebetsong tse hlokang ts'ebetso e phahameng ea ho kenya mocheso.
Ntle le melemo ea tsona ea tikoloho, li-HFO blowing agents li kenya letsoho ho haneleng mocheso hantle (boleng ba R), li thusa mehaho ho boloka ts'ebeliso e ntle ea matla. Ha indasteri ea kaho e ntse e beha pele botsitso, ho amoheloa ha theknoloji ea HFO-blowing agents e emela mohato oa bohlokoa oa ho fokotsa tšusumetso ea eona ea ho futhumala ha lefatše.
Ho netefatsa hore ho latela Melao
Ho latela melaoana ea morao-rao, ho bohlokoa ho hlahloba metsoako ea ho foka e sebelisoang lihlahisoa tsa hau tsa foam ea spray. Ho fetohela ho metsoako ea ho foka ea HFO ha ho u thuse feela ho fihlela litlhoko tsa taolo empa hape ho beha khoebo ea hau e le moetapele mekhoeng e tsitsitseng.
Mehato e meng ea ho netefatsa hore melao ea lateloa ke ena:
- Lula U Tsebisitsoe: Lula u tseba melaoana ea morao-rao le litekanyetso tsa indasteri tse amanang le li-agent tse phatlohang.
- Lekola Lihlahisoa tsa Hao: Etsa tlhahlobo e felletseng ea lihlahisoa tsa hau tse seng li ntse li le teng ho khetholla leha e le life tse sebelisang li-HFC.
- Fetohela ho li-HFO: Phetohelo butle-butle ho ea ho li-HFO blowing agents, ho sebelisa melemo ea tsona ea tikoloho le ts'ebetso.
- Ruta Sehlopha sa Hao: Koetlisa basebetsi ba hao ka melemo le mekhoa ea ts'ebeliso ea li-agent tsa ho butsoela tsa HFO ho netefatsa phetoho e boreleli.
Ka ho amohela disebediswa tsa ho foka tsa HFO, o ka netefatsa hore dihlahiswa tsa hao tsa foam ya spray di latela melao ha o ntse o kenya letsoho tikolohong e phetseng hantle. Mokgwa ona wa ho nka bohato ha o fokotse dikotsi tsa taolo feela empa hape o hokahanya kgwebo ya hao le tlhoko e ntseng e hola ya ditharollo tsa meaho e tsitsitseng.
