Tsebo ea Indasteri: Litšebeliso tsa Polyurethane Catalyst

Indasteri ea li-catalyst tsa polyurethane e bapala karolo ea bohlokoa tlhahisong ea li-foam tsa polyurethane, e leng se nolofalletsang bahlahisi ho ntlafatsa sekhahla sa karabelo, botsitso ba foam, le thepa ea ho qetela ea sehlahisoa. Li-catalyst tsa polyurethane li bohlokoa ho tsamaiseng liketso tsa lik'hemik'hale lipakeng tsa li-polyol le li-isocyanate, ho netefatsa hore thepa ea polyurethane, joalo ka li-foam tse tenyetsehang, li-foam tse thata, le li-foam tsa spray, li thehoa ka litšobotsi tse lakatsehang tsa mechini le tsa mocheso. Khetho ea li-catalyst e ama haholo katleho, boleng le boemo ba tikoloho ba litsamaiso tsa foam tse hlahisoang.

Mefuta ea Li-Catalyst tsa Polyurethane

Li-catalyst tsa polyurethane li ka aroloa ka mefuta e 'meli ka kakaretso:

1. Li-Catalyst tsa Amine
   Li-catalyst tsa amine li sebelisoa haholo indastering ea foam ea polyurethane, haholo-holo li-foam tse tenyetsehang, meaho ea li-microporous, le lits'ebetsong tsa elastomer. Li thusa ho laola tekano lipakeng tsa liketso tsa ho foka le tsa gelling. Li-catalyst tsena li loketse haholo lits'ebetsong tse hlokang ho nepahala ha sebopeho sa li-pore le ho mamella ha mechini.

   Mohlala: MXC-RE13
   MXC-RE13 ke sesebelisoa sa ho baka se thehiloeng ho amine se nang le lits'ebetso tse fapaneng. E sebelisoa hofoam e tenyetsehang e tsitsitseng ka ester, e leng sa bohlokoa bakeng sa lits'ebetso tse hlokang ho tšoarella le boiketlo, joalo ka thepa ea ka tlung le libethe. MXC-RE13 e boetse e sebelisoa hobubble e nang le masoba a manyenyane, e bobebe ebile e tiile, e leng se etsang hore e lokele lits'ebetso tse kang litulo tsa likoloi. Ho feta moo, e sebelisoa holi-elastomer, e fanang ka ho tenyetseha le ho tiea ho babatsehang.

2. Li-Catalyst tsa Tšepe
   Ka lehlakoreng le leng, di-catalyst tsa tshepe di kgothaletsa di-polymerization (gelling) le di-crosslinking (curing) ditsamaisong tsa polyurethane. Di-catalyst tsena hangata di nkela ditsamaiso tsa setso tse thehilweng ho tin sebaka, haholo-holo maemong ao melao ya tikoloho e hlokang phokotso ya di-heavy metal, tse kang mercury, lead, kapa dibutyltin.

   Mohlala: MXC-B20
   MXC-B20 ke sesebelisoa sa ho baka se thehiloeng tšepeng se sebetsang e le mokhoa o tsitsitseng oa ho baka se bakang li-catalyst tsa setso tse thehiloeng ho tin.ha e na mercury, load, kapa dibutyltin, e leng ntho ea bohlokoa haholo maemong a thata a tikoloho. MXC-B20 e bontšaho feto-fetoha ho tlaselemonko o fokolang, ho netefatsa polokeho ea basebetsi le ts'ebetso ea sehlahisoa. Ke sesebelisoa se loketseng sa ho holisamaqephe a tenyetsehang, lifoam tse tenyetsehang tse nang le bongata bo phahameng, liforo tsa sprayleliforo tse thataHo tsamaellana ha eona le mefuta e mengata ea liforomo ho e etsa khetho e ratoang lits'ebetsong tse hlokang ts'ebetso e phahameng le thepa e mosa ho tikoloho.

Masimo a Kopo ea Li-Catalyst tsa Polyurethane

Li-catalyst tsa polyurethane li bohlokoa tlhahisong ea mefuta e fapaneng ea foam, e 'ngoe le e 'ngoe e na le ts'ebeliso e fapaneng indastering ho tloha likoloing ho ea kahong:

1. Foam e Tenyetsehang
   Lifomo tsa polyurethane tse tenyetsehang ke thepa e bonolo, e mamellang serame e atisang ho sebelisoa lits'ebetsong tsa ho roka tse kang thepa ea ka tlung, materase le litulo tsa likoloi. Li-catalyst tsa amine tse kang MXC-RE13 li sebelisoa ho ntlafatsa sebopeho sa sele sa foam, ho fana ka boiketlo bo phahameng le ho tšoarella. Boteng ba li-stabilizer tse thehiloeng ho ester bo netefatsa ts'ebetso e tšoarellang nako e telele, esita le tlas'a khatello ea mechine.
2. Foam e Tiileng
   Lifomo tse thata tsa polyurethane li khetholloa ka thepa ea tsona e phahameng ea ho thibela mocheso le ho tiea ha sebopeho. Li sebelisoa hangata hokaho(diphanele tsa ho kenya mocheso, mapolanka a marulelo) lelisebelisoa tsa motlakase(lihatsetsi, dihatsetsi). Dikhatalyst tse kang MXC-B20 di ntlafatsa tshebetso ya ho lokisa foam, di ntlafatsaho thibela mochesole botšepehi ba sebopeho ha ka nako e ts'oanang ho fokotsa mesi e hlahisoang ke lik'hathale tsa tšepe tsa setso.
3. Foam ea Spray
   Li-spray polyurethane foam (SPF) li sebelisoa haholo kahong bakeng sa ho kenya mocheso le ho kenya marulelo, li fana ka ts'ebeliso e ntle ea matla le ho koala moea. Li-catalyst tsa amine le tsa tšepe li sebelisoa ho laola boemo ba ho phahama ha foam, ho khomarela li-substrate, le nako ea ho fola. MXC-B20, mohlala, e ntlafatsa litsamaiso tsa SPF ka ho khothaletsa ho fola ka potlako ntle le tšusumetso e mpe ea tikoloho ea li-catalyst tse nang le tšepe e boima.
