Ukusebenzisa kwe-tetrabutyltin (TBT), oku ngenkathi yicala lokuncedisiyo, kungene amahlelo esincinci lokugcina isiqembu sasemanzini; Ngokulandelani, i-antifoulant usebenzisa ukuvumela ukukhubaza kweentsha kwiikholwane zombhalo. Ngokushesha wayegcinwa ukuze lisethembele isinqumo, kodwa TBT inceda imikhonto emnandi kwiseqembu sasemanzini ngoba icala lingancamathelanga ngendlela yakhe yokudluliswa futhi lizigqweme ukukhishwa nokukhupha kwiisidima, okuyinto engavakaleni ikhiyele 18 miyiwo phambi kokuthi kusebenzi.
TBT uya kubona isiqephu esithunyelwe ngokupheleleyo kwiindlela ezifana nezilwanyana. Ukuphumelela kunye nomva kuphela emibhalweni wezilwanyana, amacrayishte neefishIlanga lalayiphi iindlela zendawo zenqanawa zeziqephu sezilwanyana ezinamandla ukuba ziphumeleyo ngenxa yokugcina kwabo ngaphakathi. Ngoku yayingezwe imigomo apho leminyango azisebenza ngokubonisa okanye ukugcina iinhlobo, futhi ngokulandelana nokuba zizwa njenge-endocrine disruptors ngoba ukusetyenziswa kwezinto eziphumeleyo kukuba zingabhedelela izindlu zombuso ngeminyaka engapheleleyo (ukubuya & ukudibana umetabolism ukufundiswa) ngokusebenzisa amandla okungaba ubungakanani.
Ngokubhale, TBT inokuthatha kwindlela yokuhlala yomoya ngokushesha. Ukuphumula kwiseveni, TBT inakwazi ukusetyenziswa phakathi komhlaba, amanzi esikhehleni kanye nezilungu zomhlaba ezinethunywa ngamandla okukhapho kakhulu ngokusebenza kwesikhatsi. Umgama womthetho wokuthatha kuhluke kwe-TBT kwindlela yokuhlala yomoya yasekululekweni yasemanzini yayibonisa ngokulandelana nomaqashane osebenzayo njengomncedisi nokuba nokulima ekhaya.
Kodwa, izicwangciso ezingahlanganiswa nge-TBT azifunekayo ukugcina ngokushesha kwiindlela yokuhlala yomoya kuphela kunye nokuthi umphakathi wakho ube ngexhasi. Speigel wayathetha ukuba iindlela zezilungu zithintelelwa nge-TBT zizihamba ngokubhidwa kwezinye izinto, njengokufumanekako imiphumela eyahlukileyo, amandla amahhwebhu nokuthi abantu abangena babalulekanga ukubuyisela. Lolu hlobo lwe-TBT lavela lokuba luhlola ukuthi luvunyelwe njengecarcinogen yesintfo esiqhathaneni sese-Cancer (IARC), meaning ifayise cancer kumntu.
Kwiqhagambo leyiTBT iyayityelelwa ngokukhangana njengomthwalo wemibhuleni, kodwa ingakhiwo ukuba yintoni kuhlanganiswa ngesiphumo sokuphucula iipoliviniklaide (PVC) esisetyenziswa ukuba isebenzeleli. Ngokuhlala yiTBT inceda umphumelelo kunye nokugcina kwezi zinto ezithethwayo, ukuhlola kwabo kwiimbali emithathu ngezikhathi zocwaningisela, uzisebenza kunye nokuthatha amandla apho akusetyenziswa, ayihlobene kunye nokubheka, kufuneka lokho kuzoqhathanisa ukungabiko lwesikhatsi; ndawonke into elizama ukuyenza ukulingana nendawo yokushintsha.
Ngokuhlala ezininzi izicatshululo ezifumanekayo, yiTBT ifuneka ngokuncane lishutelwe kusekupheni kwezi zinto zokuthumela kwiinkomo zakwasemaqhileni ngokushintshwa kwezi zinto zokusetshenziswa kunye nokuthumela. Ku-[6, 7]?zingaphambili ezinye izidliso zazithutha imigomo yokusetshenziswa yiTBT kumithwalo okanye ikhompyutha obeseleleyo kunye neentsha, njengonye Europe Union (EU), Japan okanye USA. Ngokuhlala, Isithunyiswa Sosintlango Somlando (IMO) sithumelela uphawu olusetshenziswa ukuba alitshene tributiltin kumithwalo okanye ikhompyutha obeseleleyo esetshenziswa kumakhompyutha.
Kulungile, ngoko ke kuhluke iindlela ezidinga ukwenza ukuba kuqhamuka umphathiso wokubhaleka kwesayithi (TBT) ngokusetyenziswa kakhulu kumhlaba wezwe lomkhulu elingana noma alunxibeleleyo amandla nokuziphatha. Ukuthi kube yonke amagama asebenzise TBT kwiimboniso lemfuthe neentsha kwindawo yokuhlala kumhlaba kuya kufuneka kuhlula kakhulu.
Iinkampani zethu zihlaleni ne-TBT elithileyo nesiphumo esisodwa sokuthiwa kwebutile Tin, nesiphiwo sephakathi lokuthiwa kokuba nokukhombisa. Siyaziqinisekisa ngokuthi umthwalo wenkcwadi yethu yinhloko yakho yokuthiwa, kunye nokuthiwa ngonyaka engaphambili, nokuthiwa ngonyaka olungaphansi, uzokusetyenziswa kwezinye izinkinga ezindala, nokuqinisekiswa kwezindlela ezindala ezindaweni ezininzi.
i-Tetrabutyltin ifumanekile kwi-National Chemical Park - Ningxia Ningdong New Materials Park okungu-comprehensive supplier ethetha ukuhlola, uphawuliweyo nokuthengisa kwisezantsi zokuthi zibutyltin nezoctyltin kunye nesintshumeletho ezimbini. Ningxia Lingshi yityiphumo elikhulu lokuthi i-butyltin, i-octyltin kunye nesintshumeletho ezimbini.
Siyinkqubo enkulu yesinye esikhashana somsebenzi wesintshumiweyo sokuqala sokuhlola, sifumanekile amandla amakhulu kuhlukeleso lomsebenzi waseTetra butyltin. Amakhefu akhona abahluleka kunye nemibhalo eziphakamiswayo ayiqinisekise ukuthatha imibophelelo yokuphawulwa, imibophelelo yokubhaliweyo ezinikezeli kunye namanye amagama alandelwayo kumalunye umntu.
izinyathelo zentloko neentsimbi ezifundekayo, amagama okugcinwe kwenze amandla angaphambili yokuthuthukisa, amahlukwene atholakaleyo asikhwetha ukuba akhawuleke ngendlela yobuninzi bokuphela, kodwa abe ngenqanawe ngaphandle kwemfazwe nokubheka nokuvikelela e-Europe kanye nomphahla waseMerika kunye no-Asia Ekhanda kunye nokulandelana nokumhlaba kunye nokufakelwa ngaphandle komhlaba, kunye namabangeni amanye kunye namakhulu. Ngoku sikhona sesithathu esincane kusendlululo sokuhlola nokuthiwa, kunye nokungena China ekuthiwayo i-Organotin Industry. Ngesinyathelo esingaphambili esifundekayo nokuhlola, amagama atholakalayo asikhwetha ukuba akhawuleke ngendlela yobuninzi bokuphela, kodwa abe ngenqanawe ngaphandle kwemfazwe nokubheka nokuvikelela e-Europe, Europe, nomphahla waseMerika, no-Asia Ekhanda kunye nokulandelana nokumhlaba kunye nokufakelwa ngaphandle komhlaba, bayenza isixhumanisi somsebenzi wesayithi esilandelana nesayithi esilandelayo.
