Tlhaloso ea Meta: Fumana masimo a fapaneng a ts'ebeliso ea li-catalyst tsa polyurethane, ho tloha ho li-foam tse tenyetsehang ho isa ho insulation e sebetsang hantle. Ithute kamoo litharollo tsa rona tse ncha tsa li-catalyst li tšehetsang boleng, katleho le ho latela tikoloho tlhahisong ea PU.
Selelekela
Polyurethane (PU) ke polymer e feto-fetohang e sebelisoang liindastering tse se nang palo, 'me li-catalyst tsa polyurethane li bapala karolo ea bohlokoa ho laoleng tlhahiso ea eona. Jwalo ka moetsi ea ka sehloohong oa li-catalyst tsa PU tse sebetsang hantle, re fana ka litharollo tse ikhethileng tse etselitsoeng ho ntlafatsa liketso tsa foam, ho phekola le ho hokahanya litsamaisong tsa polyurethane. Sehloohong sena, re hlahloba masimo a bohlokoa a ts'ebeliso eali-catalyst tsa polyurethane, e bonts'a kamoo ba tšehetsang boqapi le ts'ebetso ho pholletsa le makala a mangata.
1. Foam e tenyetsehang ea Polyurethane
Likopo:Thepa ea ka tlung, materase, litulo tsa likoloi, lithapo tsa lieta.
Karolo ea Motlatsi:Litsamaisong tse tenyetsehang tsa foam, li-catalyst li thusa ho leka-lekanya liketso tsa gelling (polyol-isocyanate) le bubble (water-isocyanate) ho hlahisa meaho e tšoanang ea lisele, maikutlo a bonolo le ho mamella hantle.MXC-37 (DMAEE)le MXC-A1 (BDMAEE) li fana ka mesi e fokolang le taolo e phahameng ea karabelo, e leng se etsang hore li be ntle bakeng sa liindasteri tsa likoloi le tsa masela moo ho latela melao ea VOC ho leng bohlokoa.
2. Foam e tiileng ea Polyurethane
Likopo:Lihatsetsi, lihatsetsi, liphanele, liboto tsa ho kenya mocheso, ho kenya mocheso ka liphaephe.
Karolo ea Motlatsi:Liforo tse thata li hloka lebelo le potlakileng la karabelo le botsitso ba litekanyo. Li-catalyst tse kang MXC-15 (Potassium Octanoate) le MXC-T12 (Dibutyltin Dilaurate) li netefatsa sekhahla se phahameng sa phetoho le thepa e matla ea mechini. Tsena lia hlokahala ho tsamaiso ea ketane e batang, ho kenya mocheso ka har'a kaho le tlhahiso ea lisebelisoa.
3. Foam ea Polyurethane e Fafalitsoeng (SPF)
Likopo:Ho thibela ho tjhesa moaho, ditsamaiso tsa marulelo, ho tlatsa dikoti.
Karolo ea Motlatsi:Litsamaiso tsa SPF li hloka taolo e nepahetseng ea nako ea tranelate, nako ea ho phahama, le nako ea ho se be le li-tack. Li-catalyst tsa rona tse kang MXC-R40 le MXC-MB20 li ntlafalitsoe bakeng sa litsamaiso tse thehiloeng ho HFO, li fana ka monko o tlase le ho fola kapele ka ho khomarela ho hoholo. Lihlahisoa tsena li sebelisoa haholo lits'ebetsong tsa kaho tse tsitsitseng bakeng sa ho boloka matla le tšireletso ea tikoloho.
4. Liphanele tsa Foam tsa Polyisocyanurate (PIR)
Likopo:Liphanele tsa sandwich bakeng sa mabota, siling le likamore tsa polokelo tse batang.
Karolo ea Motlatsi:Mekhoa ea foam ea PIR e hloka li-catalyst tse khothalletsang ho fokotsa mocheso bakeng sa ho hanyetsa mollo hantle le ts'ebetso ea mocheso. MXC-TMA ea rona e etselitsoe ka ho khetheha ho tšehetsa meaho e tšoanang ea lisele le ho phekola ka morao ho matla, e loketseng mela ea tlhahiso e tsoelang pele le e sa khaotseng.
5. Foam le Elastomer tse nyenyane
Likopo:Li-midsole tsa lieta, mabili a setering, liphanele tsa lisebelisoa, li-damper tsa ho thothomela.
Karolo ea Motlatsi:Lisebelisoa tsena li hloka li-catalyst tse fanang ka ts'ebetso e liehang bakeng sa ho tlatsa hlobo ha li ntse li netefatsa thepa e matla ea ho qetela. Litharollo tse kang MXC-R70 le MXC-B20 li fana ka tekano e ntle lipakeng tsa phallo ea pele le pheko ea ho qetela, e ntlafatsang botsitso ba sehlahisoa le katleho ea tlhahiso.
6. Likhomaretsi le Litiiso tsa Likarolo tse peli
Likopo:Kaho, ho kopanya likoloi, ho etsa lipitsa tsa elektroniki.
Karolo ea Motlatsi:Li-catalyst tse kang MXC-T12 le MXC-BDMA li ntlafatsa matla a ho khomarela le ho tšoana ha ho fola, e leng tsa bohlokoa bakeng sa ho khomarela ho tšoarellang. Lihlahisoa tsa rona li tšehetsa mesi e fokolang ea VOC le ho lumellana le mefuta e mengata ea litsamaiso tsa polyol le isocyanate.
Hobaneng re ka re Khetha?
Re fana ka:
Li-catalyst formulations tse ikhethileng bakeng sa litlhoko tsa hau tse ikhethang
Tšehetso e felletseng ea tekheniki ho tloha laboratoring ho isa tekanyong ea tlhahiso
Litharollo tse nang le mosi o fokolang le tse sireletsang tikoloho
Thepa e tšepahalang ea lefats'e ka bophara le phepelo e tsitsitseng
Hore na o hlahisa foam e mamellang haholo, insulation e bolokang matla, kapa li-elastomer tse tšoarellang, pokello ea rona ea li-catalyst e fana ka ts'ebetso e pakiloeng le katleho ea ts'ebetso.
Iteanye le rona
Na o se o loketse ho ntlafatsa diforomo tsa hao tsa polyurethane? Ikopanye le sehlopha sa rona ho ithuta haholwanyane ka letoto la rona la di-catalyst tsa MXC mme o kope disampole kapa maqephe a data a tekheniki.
