Dibutyltin Dilaurate: Sesebelisoa se Fetohang se nang le Lisebelisoa tse fapaneng
Dibutyltin dilaurate, e tsejoang hape e le DBTDL, ke sesebelisoa se sebelisoang haholo indastering ea lik'hemik'hale. Ke ea lelapa la motsoako oa organotin 'me e nkoa e le ea bohlokoa ka lebaka la thepa ea eona ea matla ho mefuta e mengata ea lik'hemik'hale. Motsoako ona o feto-fetohang o fumane lits'ebetso ts'ebetsong ea polymerization, esterification le transesterification, e leng se etsang hore e be karolo ea bohlokoa tlhahisong ea lihlahisoa tse fapaneng tsa indasteri.
E 'ngoe ea litšebeliso tse ka sehloohong tsa dibutyltin dilaurate ke sehlohleletsi tlhahisong ea mapolanka a polyurethane, liphahlo le likhomaretsi. Indastering ea polyurethane, DBTDL e thusa ho theha likhokahano tsa urethane, tse bohlokoa bakeng sa nts'etsopele ea thepa ea boleng bo holimo ea polyurethane. Ts'ebetso ea eona ea matla e etsa hore ho be bonolo ho kopanya lihlahisoa tsa polyurethane tse nang le thepa e lakatsehang joalo ka ho tenyetseha, ho tšoarella, le botsitso ba mocheso.
Ho feta moo,dibutyltin dilauratee sebelisoa e le mohloli oa ho qaptjoa ha li-polyester resin. Ka ho khothaletsa karabelo ea esterification le transesterification, DBTDL e thusa tlhahiso ea lisebelisoa tsa polyester tse sebelisoang ho etsa masela, ho paka, le lits'ebetso tse fapaneng tsa indasteri. Karolo ea eona ea bohlokoa lits'ebetsong tsena e kenya letsoho ntlafatsong ea boleng ba sehlahisoa le ho ntlafatsa katleho ea tlhahiso.
Ntle le karolo ea eona ho polymerization le esterification, dibutyltin dilaurate e sebelisoa tlhahisong ea li-silicone elastomers le sealants. Ts'ebetso ea catalytic ea DBTDL e thusa ho hokahana ha li-polymer tsa silicone, tse lebisang ho thehoeng ha lisebelisoa tsa elastomeric tse nang le thepa e ikhethang ea mochini le ho hanyetsa mocheso le lik'hemik'hale. Ho feta moo, dibutyltin dilaurate e sebetsa e le sesosa sa pheko ea li-silicone sealants, e nolofalletsang nts'etsopele ea lihlahisoa tse tšoarellang le tse hanyetsanang le boemo ba leholimo tse sebelisoang haholo meahong le lits'ebetsong tsa likoloi.
Ho feto-fetoha ha maemo a dibutyltin dilaurate ho atoloha ts'ebelisong ea eona e le sesosa sa ho kopanngoa ha li-intermediate tsa meriana le lik'hemik'hale tse ntle. Thepa ea eona ea matla e bapala karolo ea bohlokoa ho tsamaiseng liphetoho tse fapaneng tsa manyolo, ho kenyeletsoa acylation, alkylation, le condensation reactions, e leng mehato ea bohlokoa tlhahisong ea metsoako ea meriana le lik'hemik'hale tse ikhethang. Tšebeliso ea DBTDL e le mohloli oa ts'ebetso lits'ebetsong tsena e kenya letsoho kholisong e sebetsang ea lihlahisoa tsa lik'hemik'hale tsa boleng bo phahameng tse nang le mekhoa e sa tšoaneng.
Ho sa tsotellehe tšebeliso e atileng e le tšubuhlellano,dibutyltin dilauratee hlahisitse matšoenyeho mabapi le litlamorao tse ka bang teng tikolohong le bophelo bo botle. Joaloka motsoako oa organotin, DBTDL esale e le taba ea ho hlahlojoa ka taolo ka lebaka la chefo ea eona le ho phehella ha eona tikolohong. Boiteko bo entsoe ho fokotsa tšusumetso ea tikoloho ea dibutyltin dilaurate ka nts'etsopele ea li-catalyst tse ling le ho kenya ts'ebetsong melaoana e thata e laolang ts'ebeliso ea eona le ho lahla.
Qetellong, dibutyltin dilaurate ke mohloli oa bohlokoa o nang le lits'ebetso tse fapaneng indastering ea lik'hemik'hale. Karolo ea eona ho polymerization, esterification, silicone synthesis, le liphetoho tsa manyolo e totobatsa bohlokoa ba eona tlhahisong ea mefuta e mengata ea lihlahisoa tsa indasteri le tsa bareki. Le ha thepa ea eona ea matla e thusa ho tsamaisa lits'ebetso tse fapaneng tsa lik'hemik'hale, ts'ebeliso le taolo e nang le boikarabello ea dibutyltin dilaurate li bohlokoa ho fokotsa likotsi tse ka bang teng tsa tikoloho le bophelo bo botle tse amanang le ts'ebeliso ea eona. Ha lipatlisiso le boqapi li ntse li tsoela pele, nts'etsopele ea li-catalyst tse tšoarellang le tse sireletsehileng li tla kenya letsoho ntlafatsong ea indasteri ea lik'hemik'hale ho ea mekhoeng e baballang tikoloho.
