Sethibela-mafu sa Spray Foam se Entsoe ka Eng?
Ho thibela foam e fafatswang hangata ho etswa ka dikarolo tse pedi tse kgolo tsa mokelikeli: di-isocyanate le di-polyol. Ha dikarolo tsena tse pedi di kopantswe mmoho, di arabela ho etsa foam e atolohang le ho thatafala. Senotlolo sa tshebetso ena ke tshebediso ya di-catalyst tse ikgethang tsa polyurethane tse laolang sekgahla sa karabelo, ho netefatsa hore foam e fola hantle mme e fihlella dibopeho tse lakatsehang tsa ho thibela.
1. Li-Isocyanate:
Li-isocyanate ke lik'hemik'hale tse arabelang tse bapalang karolo ea bohlokoa ho thehoeng ha foam ea polyurethane. Li arabela le li-polyol ho theha matrix ea polymer ea polyurethane, e fang foam sebopeho sa eona le ho tšoarella ha eona.
2. Li-polyol:
Li-polyol ke karolo e 'ngoe ea bohlokoa ho fafatseng foam ea spray. Li kopantsoe le li-isocyanate ho hlahisa foam ea polyurethane. Mofuta le mokhoa oa ho etsa li-polyol li ka fapana, ho lumella litšobotsi tse fapaneng tsa foam, tse kang ho tenyetseha, ho tiea le ho teteana.
3. Li-Catalyst tsa Polyurethane:
Li-catalyst tsa polyurethane li bohlokoa ho laola karabelo lipakeng tsa isocyanate le polyols. Li-catalyst tsena li netefatsa hore foam e atoloha le ho fola ka nepo, e fana ka thepa e lakatsehang ea ho thibela ho ruruha. Mohlala,MXC-A33Sesebediswa sa catalyst se sebedisetswa ho hlahisa dipululana tsa foam tse bonolo, tse thata, le tse thata hanyane, e leng se etsang hore e be le bokgoni bo fapaneng bakeng sa ditlhoko tse fapaneng tsa ho kwahela. E ka boela ya qhibilihisa ka hara di-solvent tse kang MEG, DEG, le BDO, e leng se dumellang ditshebediso tse fapaneng. Ka lehlakoreng le leng,MXC-Te sebelisoa tlhahisong ea foam e tenyetsehang ea polyether, foam e bōpiloeng, foam e thata hanyane, le foam e thata, e leng se etsang hore e be e loketseng bakeng sa lits'ebetso tsa ho kenya mocheso oa likoloi.
Litšebeliso tsa Spray Foam Insulation
Setlolo sa ho thibela ho bola ha foam se sebediswa ka mefuta e fapaneng ya dikopo, ho kenyeletswa:
- Ho kenya mocheso malapeng: Foam e fafatsang e sebediswa hangata malapeng ho sireletsa mabota, marulelo le marulelo a marulelo, e thusang ho fokotsa ditjeo tsa eneji le ho ntlafatsa boiketlo.
- Mehaho ea Khoebo: E boetse e sebelisoa mehahong ea khoebo ho sireletsa libaka tse kholo mochesong, e fana ka tikoloho e laoloang haholoanyane le ho fokotsa litšenyehelo tsa ho futhumatsa le ho pholisa.
- Likopo tsa Liindasteri: Sethibela-mafu sa spray foam se sebediswa dibakeng tsa diindasteri ho thibela diphaephe, ditanka le disebediswa tse ding ho thibela tahlehelo ya matla le ho ntlafatsa bokgoni.
Qetello
Ho sireletsa foam ea spray ea polyurethane catalyst ke thepa e sebetsang haholo e fanang ka thepa e phahameng ea ho sireletsa. Tšebeliso ea li-catalyst tse khethehileng tse kang MXC-A33 le MXC-T e netefatsa hore foam e fola hantle, e fana ka litšobotsi tse lakatsehang tsa ho sireletsa bakeng sa lits'ebetso tse fapaneng. Ebang ke libakeng tsa bolulo, tsa khoebo, kapa tsa indasteri, ho sireletsa foam ea spray ke sesebelisoa sa bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea matla le botsitso ba sebopeho.
