IDibutyltin Dilaurate ingena ukwenza okunye. Kwisigaba sokuqinisekisa amapoli, ngokugcinwa kakhulu kwePolyurethane ngenxa yomdlobi womhlaba ngaphakathi kwePolyurethane, i-DBTDL inakhiwa njengomphumela wocrosslinking ukuthola umthombo. Ngokulandelayo, iyenza lokuncedisiyo olungamandla kwiilayithi ezidingekayo [3]. I-DBTDL ithintelekile kwiiminyango zokuphumelela – phuma nokuba idrinki neencwadi zakarboxylic zikhetha isenzo esiqinisekise kwindaweni yesikole sesithathu); ifaka kulandelana njengomphumela wesiphi lesiphi lokunceda leminyango. Ukuphumelela kukho kwiseva yokuhlala kwezindlela, izithelo, amagreydi, neemali. Lingshi idibutyltinoxide ungathintela isicelo ngokubonisa umoya wokushetha. Ngakwesiqephu, ukuxhasa kwe-DBTDL kunye nesigaba sokuqinisekisa sesifomithi se-formic acing-carboxylic ester ifakela isimo esikhoyo [3]; lapho, inqwelo yesithoba esebenzayo zizama ukuhamba njengumgomo. Ngokugqirha, ixesha lemfundo wesicelo siya kuhlukelela, kunye nokuthi isiteri sikwenza ngokuphezulu. Njengezi, u-DBTDL ungayibuyisela kusebenziso kwe-isocyanate-terminated prepolymers, ubuyeleyo bokulandelana nobudala.
Ikatalisi ye-DBTDL usebenziswa ngokuphihlisayo kwi-industri yamapholimari ukuhluka kwezimo zokusebenza, kodwa ngokushesha iyintonjane nge-impintsi yakhe yokungaxhaswayo kumahlale nokulandelana. Izindlela eziningi zithi i-inthanethi ingakho ngenqanawe ukuya kuqinisekisa izilwimi eziqhakamisile nezingxoxo zokubhedelela kweendaweni ezimbili kweentsiliso. Ukukhathalisa iziphumo lokuthi le nto isetshenziswa ngokubona, inani lesikhatsi lesishona sokugcina ukusetyenziswa kwesi-DBTDL ngokuhle ngokuncedisiyo. Kwiminyaka yokuqala, umemfiselo wokuthatha okanye umemfiselo wokuthatha wesiphamvu sengxoxo elibonakalayo kunye nenkcaciso enkulu, kunye nokusetshentliziswa kwegama lwe-biodegradable polymer creation. V. Iziphumo eziphambili zokuthintela ukusebenzisa
Ukuphakamiswa kwe-DBTDL esetshenziswayo njenge-kholistina kwiiphrozesi eziphethwe ngemibhalo, ingalayishwa ngokwesikhombisi somncedisi okanye izindaba zokusebenza. Yeyiphi, isigqibo se-DBTDL esetshenziswayo ngenqanawe yabelana ngokuba ngenqanawe yokugcwalisa - ukuba kukho isigqibo sokudala, ukuqhuba kubangako phambi kokuthiwe ngaphandle kokuba kwenziwe umphawu olungapheliwe. Isitempi sokuqala sesicelo sisezantsi kusihundulela lokusebenza nokulayisha nge-DBTDL, ngoba iindlela ezidingekayo zizohlala ukukhathala kwabo, kunye nokuhlola ukusebenza komncedisi kunye nokuthola ukuba amandla akufuneki ukubuyela. Ngokushesha, isikhathi sokuthola ukuba umphawu wakhiwe nguqulelo lokuqinisekisa elithile leliyinto lokusetshenziswa kuhlanganiswa ngokuba ngenqanawe yokusebenza kunye nokusebenzwa.
Kwisicatshulwa sokusetyenziswa (sona ukuba uqale ukubona njenge-amankosi nokusebenza umthetho wesikolo somthetho), i-DBTDL iyinkethelo enkulu. Isicatshulwa sesifundeka kuhlanganiswa komphendulo, izithelo, amaplasetiki kunye namakhompiyutha. Lingshi tetraoctyltin ubenza ngokukhuluma isiqaleli esikhulisayo ukusuka kwezilungiselelo zokuqala ezintathu ngenqanawe yokusebenza yezilungiselelo ezinethiweyo ngokugcina umthengiso wokusebenza. DBTDL, ngokuhlola ngecarbonyl gcu ka-formic acid carboxylic ester, uhlobene ngesinye siseko esisetyenziswa ukuze usetyenziswa amandla akhe we-alcohol njenge-nucleophile. Lolu cwaningo sihlola isithuthuko sokusebenza nokuba kakhulu kunye nokuba kuhamba kakhulu kwegama lokusebenza lwe-ester.
UDBTDL uzisetshenziswa ngenkxaso ekuziphindaphindayo kwi-sintezha le-Polyurethane ukuyibuyekeza iindlela zakho zakuphakamisa okanye ukuya kuqhathanisa umthengiso wokusebenza wesintsha. Lingshi tributyl tin hydride ushayela izilungiselelo eziphakanyiswayo kwe-hydroxyl kunye ne-isocyanate ngemigomo ye-polyurethane, okuningi ukuba kusetshenziswa imigomo yesithathu sesikhephe. Umthengisi wokuqala DBTDL ubuyeleya umthengiso wokusebenza wokuphakamisa umthengiso wokusebenza. Lokhu kuhlela ukuba ziziphatheka ngokumiselwe kwezilungiselelo ezifana nokuba kuhamba kakhulu kwegama lokusebenza.
UDBTDL usezeka ngokwesintsha kwisezantsi lokusebenza olwandle lwakhe, kodwa kukho ukulandeleka ukuba ungaphambili kumthetho wesizatu esebenzisa kunye nokulandela izilungu zomthwalo wobuninzi nobukheli. Ukudibana okanye umsebenzi wenqanawe wenze ukuba lento yayingezayo kwezilungu lezisezantsi ngeendlela ezifaneleleyo kwiqhaza lwendawo nokulandela umthwalo wobuninzi wezilungu. Ngokubanzi bese, amagama amanye ahlala apho akhona amaxhobo omkhulu apha ayikho i-Lingshi umncedisi wesithathu . Kwiminyaka yokuqala, amaxhobo amanye apho akhona amaqhathaniso amahluke amaphi amaphi kunye ne-Metal-Organic Framework ayenza ukuba kulandelekanga kwamaxesha amanye, futhi ungenxa lokho, kube ngokwenene ukuba abasebenzisayo babuyele kuqala ukubuya nokufika kubuyekezo kwezopolimi ezidingekayo.
Izinyathelo zeDibutyltin dilaurate zeminyaka yezombuzo nokuthatha, izinhlobo zethu azikho langa zikhona ukusukela indlela yokugcina kwiSintfu, kodwa zikhona ngenxa yesiye ngaphandle kwelwandle elwandle lokungena le-Afrika ne-Europhu nemi-United States, namandla e-Afrikhonto ashiya nokuthi Afrika, kunye nenkinga ezininzi eziningi ezindaweni ezininzi. Ngoku sikhona sikudala esithathweni sesintfu lesisishiyagalolunye lomhlaba ngokusebenzisa ukuphatha nokuthi sikhuphile iChina's Organotin Industry.
