I-Dibutyltin i-Dilaurate: isilinganiselo esiguquguqukayo ngezicelo ezahlukahlukene
I-Dibutyltin ye-Dilaurate, eyaziwa nangokuthi i-DBTDL, i-catalyst esetshenziswa kabanzi embonini yamakhemikhali. Kungokomndeni we-organin compound futhi kubaluleke kakhulu ngezakhiwo zayo ze-catalytic ezihlangeni zokusabela kwamakhemikhali. Lesi sakhiwo esiguquguqukayo sithole izinhlelo zokusebenza ku-polymerization, ukucaciswa, kanye nezinqubo zokuTkisa, okwenza kube yingxenye ebalulekile ekukhiqizweni kwemikhiqizo ehlukahlukene yezimboni.
Enye yezinto zokusetshenziswa okuyisisekelo kwe-dibutyltin ebuhlungu injenge-catalyst ekukhiqizeni amagwebu we-polyurethane, ukumboza kanye nokunamathela. Embonini ye-polyurethane, i-DBTDL kusiza ukwakheka kokuxhumana kwe-Urethane, okubaluleke kakhulu ekuthuthukisweni kwezinto ezisezingeni eliphakeme zePolyurethane. Umsebenzi wayo we-catalytic wenza ukuhlanganiswa okusebenzayo kwemikhiqizo ye-polyurethane enezakhiwo ezifiselekayo njengokuguquguquka, ukuqina, kanye nokuqina okushisayo.
Ngaphezu kwalokho,I-Dibutyltin iyabumbanaiqashwa njenge-catalyst ekubumbeni kwama-polyester resen. Ngokukhuthaza ukusabalalisa okuchazayo nokuvuselelwa kweTransterification, i-DBTDL isiza ukukhiqizwa kwezinto ze-polyester ezisetshenziswa ekwenziweni kwezindwangu, ukupakishwa, kanye nezicelo ezahlukahlukene zezimboni. Indima yayo e-catalytic kulezi zinqubo inomthelela ekuthuthukisweni kwekhwalithi yomkhiqizo kanye nokwenza kahle kokusebenza kahle kokukhiqiza.
Ngaphezu kwendima yayo e-polymerization kanye nokuchazwa, i-dibutyltin ebuhlungu isetshenziswa ekukhiqizeni ama-sastomers e-silicone kanye nama-sealants. Umsebenzi we-catalytic we-DBTDL usebenza ngokuwela ngokuwela ama-aillicone polymers, okuholela ekwakhekeni kwezinto ezisetshenziswayo ze-elastomeric ngempahla ekhethekile yemishini kanye nokumelana nokushisa namakhemikhali. Ngaphezu kwalokho, i-dibutyltin ebuhlungu isebenza njengomuntu okhathazekile ekuphulukeni kwama-sanisata we-silicone, okwenza ukuthuthukiswa kwemikhiqizo eqinile futhi emelana nesimo sezulu esisetshenziswa kabanzi ekwakhiweni nasezimotweni zezimoto.
Ukuguquguquka okuhlukahlukene kwe-dibuttyltin ukubumbana kufinyelela kuhlelo lwayo njengoCatalyst ekuhlolweni kwemithi ephakathi kwamakhemikhali namakhemikhali amahle. Izakhiwo zayo ze-catalytic zidlala indima ebalulekile ekwenzeni lula ukuguqulwa okuhlukahlukene kwe-organic, okubandakanya ukuhlakanipha, i-alkylation, kanye nokuphendula okuningana, okuyizinyathelo ezibalulekile zokukhiqiza amakhemikhali amakhamikhali namakhemikhali akhethekile. Ukusetshenziswa kwe-DBTDL njenge-catalyst kulezi zinqubo kunomthelela ekuhlolweni okusebenzayo kwemikhiqizo yamakhemikhali ephezulu enezinhlelo zokusebenza ezahlukahlukene.
Naphezu kokusetshenziswa kwayo okusakazekile njenge-catalyst,I-Dibutyltin iyabumbanauphakamise ukukhathazeka maqondana nemithelela yawo yezemvelo nezempilo. Njenge-organin compound, i-DBTDL ibilokhu ingumbono wokuhlolisisa okulawulwa ngenxa yobuthi bayo nokuphikelela emvelweni. Kwenziwe imizamo yokunciphisa umthelela wezemvelo we-dibutyltin ebumbene ngokuthuthukiswa kwamanye ama-catalysts kanye nokusetshenziswa kwemithethonqubo eqinile elawula ukusetshenziswa kwayo nokulahlwa kwayo.
Ekuphetheni, i-dibutyltin i-pilaurate iyinhlangano ebalulekile ebalulekile ngezicelo ezahlukahlukene embonini yamakhemikhali. Indima yayo e-polymerization, ukucaciswa, ukuguqulwa kwe-silicone, kanye nokuguqulwa kwe-organic kugcizelela ukubaluleka kwayo ekukhiqizweni kwemikhiqizo ehlukahlukene yezimboni nakuMthengi. Ngenkathi izakhiwo zayo ze-catalytic zisebenza ngokushayela izinqubo ezahlukahlukene zamakhemikhali, ukusetshenziswa okusebenzayo kanye nokuphathwa kwe-dibuttyltin ukubuyisa kubalulekile ukuze kuncishiswe ubungozi obungahle bube nobungozi bezemvelo obuhambisana nokusetshenziswa kwalo. Njengocwaningo kanye nokwenziwa okusha kuyaqhubeka ukuqhubekisela phambili, ukuthuthukiswa kwama-catalysts azinzile futhi aphephile kuzoba nomthelela ekuziphendukeleni komkhakha wamakhemikhali maqondana nemikhuba eminingi enobungani bemvelo.
