Ukusetyenziswa kwe-tetrabutyltin (TBT), okuyikhompawundi enetyhefu, kunokuzisa iziphumo eziyingozi kwi-ecosystem yolwandle; Njengomthetho, i-antifoulant isetyenziselwa ukuvimbela ukukhula kwezinto eziphilayo kwi-boat bottom. Ngelixa ekuqaleni yayiyilelwe ukugcinwa kweendlela, i-TBT ibeka ingozi enkulu kwimimandla yaselwandle ngenxa yokuba ikhompompi idume ngokuhlala ixesha elide kwimeko yayo yendalo ethande ukufumba kwaye igxile kwintlenga ethatha umndilili weminyaka engaphezu kwe-18 ngaphambi kokuba kwenzeke nasiphi na isenzo. .
I-TBT ibe nempembelelo enkulu kwaye ibhalwe ngokucokisekileyo kubomi baselwandle. Ukuphila ukuqhubela phambili kwi-bivalves, crustaceans kunye neentlanziInokuphazamisa ngokukhawuleza ukuba iinkqubo ze-endocrine zezilwanyana ezininzi zaselwandle zibenzakalise ngaphakathi. Enye yeendlela ezisebenza ngazo ezi khemikhali kukulinganisa okanye ukuvala iihomoni, kwaye ngenxa yoko zibizwa ngokuba ngabaphazamisi be-endocrine kuba umlutha uphazamisana nolawulo lomzimba kumanqaku athile abalulekileyo (ukukhula kunye nophuhliso lokuzala kwemetabolism) ngeendlela ezinokuba yingozi. iziphumo.
Ngaphaya koko, i-TBT ibandakanyeka kungcoliseko lwamanzi ngaphezu kwayo yonke into. Ekukhululweni kokusingqongileyo, i-TBT inokusasazwa phakathi kwentlenga, amanzi olwandle kunye nezinto eziphilayo zaselwandle ezikhokelela kuqokelelo olunzima lwebhayoloji ngokutya. Elona galelo liphambili kungcoliseko lwe-TBT kwimo engqongileyo yaselwandle livela kwimisebenzi yabantu efana nokuthumela ngenqanawa kunye ne-aquaculture.
Nangona kunjalo, iziphumo ezinobungozi ze-TBT aziphelelanga kubomi baselwandle kuphela kwaye impilo yabantu isengozini. U-Speigel uthe amaphononongo anxulumanise ukuvezwa kwe-TBT kwiingxaki ezininzi zempilo, ezinje ngokusilela kwamajoni omzimba, ukusilela kwemithambo-luvo kunye nemiba yokuzala. I-TBT ngokwenene ihlelwe njenge-carcinogen yomntu yi-International Agency for Research on Cancer (IARC), oku kuthetha ukuba inokubangela umhlaza kubantu.
Akunjalo kuphela i-TBT esetyenziswa ngokubanzi njenge-antifoulant, kodwa isetyenziselwa ukuveliswa kweeplastiki ze-polyvinyl chloride (PVC) ezisebenza njenge-stabiliser. Ngelixa i-TBT iphucula ukuqina kunye nokusebenza kweemveliso ze-PVC, ukukhululwa kwayo kwezi zinto ngexesha lokwenziwa, ukusetyenziswa kunye nokulahlwa kukhokelela ekubeni negalelo elithile ekungcoleni kwendalo; kungoko enye indlela yongcoliseko ngoqoqosho lwaselwandle.
Ngokujonga imingcipheko emikhulu enxulumeneyo, i-TBT kufuneka ngokuqinisekileyo ikhutshelwe ngaphandle ekukhutshelweni ngakumbi kwi-ikhosistim yasemanzini ngezithintelo ezingqongqo malunga nokusetyenziswa nokukhululwa kwayo. Kumazwe [6, 7]?amazwe aliqela athathe amanyathelo okuthintela i-TBT kwiipeyinti ezinqanda ukungcoliseka kunye nezaleko ezifana neManyano yaseYurophu (EU), iJapan okanye i-USA. Ngaphaya koko, i-International Maritime Organisation (IMO) iye yamkele ummiselo wokuthintela i-tributyltin kwiinkqubo zokunqanda ukungcola ezisetyenziswa kwiinqanawa.
Nangona kunjalo, kusekuninzi ekufuneka kwenziwe ukuze kuthintelwe ungcoliseko lwe-TBT ingakumbi kumazwe asakhasayo anemimiselo emincinane okanye engenawo kwaphela kunye nonyanzeliso olubuthathaka. Ukuvalwa kwe-TBT kwihlabathi jikelele kwiipeyinti zaselwandle kunye neengubo ngokuqinisekileyo kuya kwamkeleka kakhulu.
Inkampani yethu ixhotyiswe ngobuchule kunye ne-tetrabutyltin ecokisekileyo yochungechunge lwe-butyl Tin, kunye nochungechunge lwe-octyl kunye neqela leemveliso. Sikholelwa ngamandla ukuba italente yeyona asethi ibaluleke kakhulu kwinkampani, kunye neqela le-RD libambelela kumbono wokusebenzisa izizukulwana, ukugcina isizukulwana, kunye nokuphanda kwangaphambili isizukulwana, ukutyhoboza rhoqo kwimiba yobugcisa, kunye nokubonelela abathengi ngokuzinza okuthembekileyo. , izisombululo ezihambelana nokusingqongileyo.
I-tetrabutyltin ibekwe kwipaki yekhemikhali yesizwe- i-Ningxia Ningdong eNtsha yezinto zePaki engumboneleli obanzi odibanisa imveliso ye-RD kunye nentengiso yoluhlu olubanzi lwe-butyltin kunye ne-octyltin kunye nezinye i-intermediate zamayeza i-Ningxia Lingshi ngumboneleli obanzi we-butyltin Octylutical kunye neyeza. abaphakathi
Singabona bavelisi bakhulu kwihlabathi be-assortment ebanzi ye-organic tin kwaye sineyona tetrabutyltin inkulu. Iingcali zethu ezinezakhono kunye nezibonelelo zale mihla zizinikele ekunikezeni izisombululo ezikhethekileyo ze-organic ezikrelekrele ezikhethekileyo zemathiriyeli yesalathiso esenziwe ngokwezifiso kunye nezinye iimveliso ezilungiselelwe abathengi bethu.
iminyaka ye-tetrabutyltin yokusebenza kunye nemvula, iimveliso zethu azihlangabezi kuphela imfuno yasekhaya, kodwa ziye zathunyelwa eYurophu nase-United States kunye ne-Southeast Asia kunye nommandla oMbindi Mpuma kunye ne-Afrika, kunye namanye amazwe amaninzi kunye nemimandla. Okwangoku sibekwe kwindawo yesithathu kwihlabathi ngokubhekiselele kumthamo wokuvelisa kwaye sikhuthaze i-Oganotin Industry yaseTshayina. Emva kweminyaka yomzamo kunye nemvula, iimveliso zethu kunye nokuhlangabezana nemfuno e-China, kunye nokuthumela kumazwe aseYurophu, eYurophu, eUnited States, eMzantsi-mpuma Asia kunye nakuMbindi Mpuma, i-Afrika kunye nemimandla eyahlukeneyo, iye yaba lunxibelelwano oluphambili kwi-intanethi. ikhonkco lokubonelela elibalulekileyo kwihlabathi.
