Li-catalyst tsa polyurethane li bapala karolo ea bohlokoa tlhahisong ea foam ea lisele tse bulehileng, e leng thepa e feto-fetohang e sebelisoang haholo liindastering tse fapaneng. Foam ea lisele tse bulehileng, e khetholloang ka sebopeho sa eona sa sele se hokahaneng, e lumella moea le metsi ho feta, e leng se etsang hore e heme habonolo ebile e bonolo. Sebopeho sena se ikhethang se e khetholla ho foam ea lisele tse koetsoeng, e nang le lisele tse arohaneng tse fanang ka sebopeho se teteaneng le se tiileng haholoanyane.
Litšebeliso tsa Foam ea Lisele tse Butsoeng
Foam e bulehileng e na le thuso masimong a mangata ka lebaka la thepa ea eona e ikhethang. E 'ngoe ea lits'ebetso tsa eona tsa mantlha ke indastering ea thepa ea ka tlung, moo e sebelisoang ho mesamo le ho etsa liphahlo ho fana ka matšeliso le tšehetso. Sebopeho sa eona se bonolo le se tenyetsehang se etsa hore e be ntle bakeng sa materase, mesamo le litulo.
Lefapheng la likoloi, foam e bulehileng e sebelisoa ho lokisa litulo le ho kenya mocheso oa molumo. Bokhoni ba foam ba ho monya molumo le ho thothomela bo ntlafatsa boiketlo le khutso ea likamore tsa likoloi. Ho feta moo, tlhaho ea eona e bobebe e thusa ho ntlafatsa katleho ea likoloi ka kakaretso ka ho fokotsa boima ntle le ho beha boiketlo kotsing.
Tšebeliso e 'ngoe ea bohlokoa ea foam e bulehileng ke indastering ea kaho. E sebelisoa e le thepa ea ho thibela foam e fafatsang e thusang ho laola mocheso oa ka tlung ka ho fana ka ho thibela mocheso. Ho hema ha foam ho boetse ho thusa ho thibela ho bokellana ha mongobo, kahoo ho fokotsa kotsi ea hlobo le hlobo.
Foam e bulehileng le eona e atile indastering ea ho paka. Matla a eona a ho boloka lintho a sireletsa lintho tse bonolo nakong ea ho romelloa le ho tšoaroa. Ho feta moo, bokhoni ba eona ba ho lumellana le libopeho tse fapaneng bo etsa hore e lokele litharollo tsa ho paka tse ikhethileng.
Karolo ea Li-Catalyst tsa Polyurethane ho Ts'ebetsong ea Foam ea Lisele tse Butsoeng
Ho kopanngoa ha foam ea polyurethane e bulehileng ho kenyelletsa karabelo e rarahaneng ea lik'hemik'hale, moo li-catalyst tsa polyurethane li leng bohlokoa. Li-catalyst tsena li susumetsa sekhahla sa karabelo le litšobotsi tsa ho qetela tsa foam. Ho na le mefuta e 'meli e meholo ea li-catalyst tse sebelisoang ts'ebetsong ena: li-catalyst tsa amine le li-catalyst tse thehiloeng tšepeng.
Li-Catalyst tsa Amine: Tsena li sebelisoa haholo tlhahisong ea foam ea lisele tse bulehileng ka lebaka la bokhoni ba tsona ba ho laola tekano lipakeng tsa karabelo ea urethane (polyol-isocyanate) le urea (water-isocyanate). Mehlala ea li-catalyst tsa amine e kenyelletsa triethylenediamine (TEDA), bis(dimethylaminoethyl)ether (BDMAEE), le N,N-dimethylcyclohexylamine (DMCHA). Li-catalyst tsena li thusa ho theha sebopeho sa sele e bulehileng ka ho susumetsa ho phahama ha foam le linako tsa gel, ho netefatsa hore ho thehoa ha sele ho ts'oanang le ho ts'oanang.
Li-Catalyst tse Thehiloeng Tšepeng: Metsoako ea Organotin ke li-catalyst tse tloaelehileng tse thehiloeng tšepeng tse sebelisoang tlhahisong ea foam ea polyurethane. Li-catalyst tsena li potlakisa karabelo ea isocyanate-polyol, li ntlafatsa litšobotsi tsa mechini le botsitso ba foam. Dibutyltin dilaurate (DBTDL) le stannous octoate ke mehlala e tloaelehileng ea li-catalyst tsa organotin tse sebelisoang ts'ebetsong ena.
Qetello
Foam ea polyurethane e bulehileng ka lisele tse ngata, ka lits'ebetso tsa eona tse ngata, e itšetlehile haholo ka liketso tse nepahetseng le tse laoloang tse thusoang ke li-catalyst tsa polyurethane. Ka ho utloisisa karolo ea li-catalyst tsena, bahlahisi ba ka ntlafatsa thepa ea foam ho fihlela litlhoko tse itseng tsa ts'ebeliso, ba netefatsa ts'ebetso e phahameng le ts'epo ho pholletsa le liindasteri tse fapaneng. Jwalo ka mofani oa li-catalyst tsa polyurethane, re inehetse ho fana ka likarolo tsa bohlokoa tse hlokahalang ho hlahisa foam ea boleng bo holimo ea lisele tse bulehileng, ho tšehetsa boqapi le bokhabane tšimong ena e matla.
