Li-catalyst tsa polyurethanee bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le bokgabane ba lihlahisoa tsa polyurethane. Har'a li-catalyst tse ngata tse fumanehang, MXC-t125 e ikhetha e le catalyst ea tšepe e se nang loto e tsebahalang ka thepa ea eona e ikhethang le lits'ebetso tse feto-fetohang. Sengoloa sena se hlahloba likarolo tse ikhethang tsa MXC-t125 le ts'ebeliso ea eona ho li-polyurethane tse thata.
Litšobotsi tsa Bohlokoa tsa MXC-t125
MXC-t125 ke sesebelisoa sa tšepe se se nang loto se etselitsoeng ho sebetsa hantle le li-cocatalyst tsa amine. Tšebelisano ena e ntlafatsa ts'ebetso ea kakaretso ea li-catalytic, e lebisang ts'ebetsong e phahameng mefuteng ea polyurethane. Ha e bapisoa le metsoako ea setso ea dibutyltin, MXC-t125 e bontša ts'ebetso e phahameng ea li-catalytic le khetho ho karabelo ea polyurethane (polyol-isocyanate). Ho feta moo, e fana ka botsitso bo betere ba hydrolysis, e leng se etsang hore e be khetho e tšepahalang bakeng sa lits'ebetso tse fapaneng tsa polyurethane.
Tšebeliso ho Polyurethanes e Tiileng
Li-polyurethane tse thata li sebelisoa haholo indastering ea ho kenya lintho ka mocheso, kaho le likoloi ka lebaka la thepa ea tsona e ntle ea ho kenya lintho ka mocheso, botšepehi ba sebopeho le ho tšoarella. MXC-t125 e bapala karolo ea bohlokoa tlhahisong ea li-polyurethane tse thata tsa boleng bo holimo ka ho netefatsa hore li-polymerization li sebetsa hantle ebile li laoloa.
1. Mosebetsi o Ntlafalitsoeng oa Catalytic: Mosebetsi o phahameng oa catalytic oa MXC-t125 o netefatsa hore karabelo ea polyurethane e tsoela pele ka potlako le ka katleho. Sena se molemo haholo tlhahisong ea foam e tiileng, moo linako tsa ho fola ka potlako li leng bohlokoa ho boloka botšepehi ba sebopeho le thepa ea ho thibela ho ruruha ea sehlahisoa sa ho qetela.
2. Ho Ntlafatsa Botsitso ba Hydrolysis: Li-polyurethane tse tiileng hangata li pepesehela maemo a fapaneng a tikoloho, ho kenyeletsoa le mongobo. Botsitso bo phahameng ba hydrolysis ba MXC-t125 bo netefatsa hore catalyst e lula e sebetsa esita le ha metsi a le teng, ka hona e ntlafatsa ho tšoarella le ho phela nako e telele ha lihlahisoa tse thata tsa polyurethane.
3. Mefuta e Meholo ea Ts'ebetso: MXC-t125 e fana ka mefuta e mengata ea ts'ebetso ka mekhoa e matla ea ho mamella. Ho tenyetseha hona ho lumella bahlahisi ho ntlafatsa ts'ebetso ea tlhahiso ho fihlela litšobotsi tse lakatsehang tsa foam, joalo ka ho teteana, matla a khatello, le ho thibela mocheso.
4. Botsitso bo Botle ba Polokelo: Botsitso ba polokelo ke ntlha ea bohlokoa bakeng sa catalyst efe kapa efe e sebelisoang lits'ebetsong tsa indasteri. MXC-t125 e bonts'a botsitso bo botle ba polokelo, e netefatsa hore thepa ea eona ea catalytic e lula e tsitsitse ha nako e ntse e ea. Botsitso bona bo fetolela ts'ebetsong e ka boleloang esale pele le e tšepahalang haholoanyane ts'ebetsong ea tlhahiso.
Ho feto-fetoha ha Litšebeliso tsa CASE
Ntle le tšebeliso ea eona ho li-polyurethane tse thata, MXC-t125 e boetse e loketse lits'ebetso tsa Likoahelo, Likhomaretsi, Li-Sealant, le Elastomers (CASE). Bokhoni ba eona ba ho sebetsa e le sesebelisoa sa ho baka gel mefuteng ena bo totobatsa ho tenyetseha ha eona le katleho ea eona ho pholletsa le litsamaiso tse fapaneng tsa polyurethane. Ho tenyetseha hona ho etsa hore MXC-t125 e be tlatsetso ea bohlokoa ho sesebelisoa sefe kapa sefe sa moetsi oa polyurethane.
Qetello
MXC-t125 ha e na leharesesebelisoa sa tšepee fanang ka ts'ebetso e phahameng ea ho kenya lintho ka har'a khetla, botsitso bo phahameng ba hydrolysis, le botsitso bo botle ba polokelo. Ho lumellana ha eona le li-cocatalyst tsa amine le mefuta e mengata ea ts'ebetso ho e etsa khetho e ntle bakeng sa lits'ebetso tse thata tsa polyurethane. Ebang e sebelisoa indastering ea ho futhumatsa, ea kaho, kapa ea likoloi, MXC-t125 e netefatsa tlhahiso ea lihlahisoa tsa polyurethane tse thata tsa boleng bo holimo, tse tšoarellang le tse sebetsang hantle.
