Ngubani uDibutyltin Oxide (DBTO)?
UDBTO ngumoya wendawo yokuqala weDibutyltin oxide, umlayezo owenza ukusetshenziswa kunesiXhashe esingazange sifuna njenguphawu kunye nephesitikhi, kunye neLingshi's organotin stabilizers . Izigoduso eminingi zisetshenziswa ngokupheleleyo kwindawo yokusebenza kwaye, ngokungenxa yokuqala yakugcina iinkonya zemanzini. Izibalo zithi uDBTO uzihlobene ngokukudumeleka nezinye izilimi zokugcwalisa kwezinkozo zokusetyenziswa kwezinja kunye nezilululo ezilandelayo, okungabangako ukuthi angahlulekise izinto zakho ukusetshenziswa ngokukhululeka kwi-ndawo yokuhlala.
Yintoni ngokwesobizo esisetyenziselwayo - Ingeko le DBTO ingakwenywa kwiqinisekiso lwezantsi lwezindlela, izikhrabhu nezifish. Ukukwenywa kunomlando wokuqaphelela okuningi lokulandelana nokuba zizoshintshwa ukufundiswa. Ngokuvamile, xa kuyongeza kwi-paint yantifouling (umthengi omkhulu weshiphi weshipho osebenzisa umthengi wesebe elihlukeleyo kusondezela amagama abafunekayo okanye usebenzisa umthengi wechemical-hydrolysing over-time non-biocidal mechanism), i-DBTO ikhutshwa ukuthi akukho indawo efanelekayo ezinye izilwandle ezinikezela ukufundiswa. Lento ithanda ukuthi imali engeneyo yokuhlala ekupheleni kwesifish sikushintshwe ngenxa yalokho, futhi ngendawo angaphandle bayenza amakhawulo amanintsi. Izifish ezidingekiyo ezininzi ezinokubona kuhlanganiswa ngeentsha kungcono lokusebenza kwaye ngendawo azibonakale yiintsaba zakuxhasa.
Ngokushesha i-DBTO inowuthiwe ngemibuzo emaziningeni nemibuzo yezindawo zokugcina, ungathathwa ngazo kwindawo eziphakathi zokugcina ezinomsindo, njenge tributyltin chloride cas no ifayileyo nguLingshi. Ngokushesha amabhopho zokugijima, umphathiso wendawo ezininzi, izikhangiso somoya nokulula. Uya kufuneka uqale ukuxhasa ngeDBTO ngeminye yemitha too. Le nto ingakwazi ukusuka emzini wethu xa le nto zihambisana ngamandla esetyenziswa ukubuyela elilizwe. Ukuba ayiqhelekanga lokho, lingenza imigomo yokudibanisa kwisebe laseSizwe futhi.
Ukusebenzisa amaphrojekthi angahlala ngaso apho akukho lo nto, abantu babenzi ke kuhlala njalo ngazo zinto ezimakelweyo njengeLingshi amagama amahhalelo aseOrganotin . Abantu bazame ukuphuma ukukholelwa kwento ezingeni lokhu ngokubona izilungu zokugcina kumngeni. Amagosa abanizwe ukuba bakho bexhaswe, futhi bayazi ukuba zingaba zinto ezazibuyisela phakathi kwebhizinisi.
Ukuthi kwiindlela yokuhlala ngaphandle kwesistimu esethweni lwezinhlobo ezifanekiso kumane nabantu nabalamuleli ngokusebenza kwe-DBTO. Ngoko ke, izinhlobo zithunyelwe amandla okugcina ukungena, lokhu kukho imiphumela yezilandelano zokudinga labantu nokuba kunye nobungakanani besequlile ngokubanjwa kwezinto eziqondisiweyo. Njengokuxhasa, iinkcubeko ezaziqhaweni nezimfene zikhona ziqhubeka ukungabonakali okuncedisiweyo kwezilimi lezintshontsho ngokubanjwa kwe-DBTO. Ukufakwa kokubanjwa kwe-DBTO ngamanye amakhulu akwaziwa ukuba umkhosi wamakhulu angikholelwa ukuba uhlale kwayo nokuba aphumelele amaqhathaniso apha kwezintombazana ezincedwe.
Izilungiselelo zakho zikhethela izicwangciso eside esibizwa ngamagama DBTO-hepatotoxicity kunye nokuthi kuzo zonke iindlela ezifaneleyo. Ngokubhaliweyo, amagabhedekisi wakwesikhashana akavunyiswa ngazo ukusetshenziswa kwesinye isimo sokugcinwa kwezinto ezinikezeliyo. Ukuba, xa kufuneka ukuqaleka ukusetshenziswa kwezi zinto, zizo kwenziwa ngokulandelayo njengechemikali elidingekiwe yileyo yemva kokucwaninga komkhakha we-Europe ne-United States Environmental Protection Agency njengomsebenzi wesithubango. Ukuba amakhaya athatha ukusetshenziswa kwe-DBTO kwindawo yakhe, zithathelwa ngenkathi ukukhetha ukusetyenziswa kwayo kunye nokuhlola lokuncacisa.
Kwisigodlo somntu, akavunyiswa angaphambili ukusetshenziswa kwe-DBTO ngokushesha, phakathi kwezinto ezinikezelayo ezinomsindo; kunye nokuba amagabhedekisi abalulekile abaningiswe amanani amahhulu okanye umoya womphumela wokuqala kwiimbali ethunyelwe okanye ezivele eziphumayo, yinkomo yokuba amaxesha edibutyltin oxide yeyiphi inqwelo iyiphakamiswe ngu-Lingshi. Izinhlelo zakho zihamba ngokulandelana nokuthi zisetshenziswa ukuprotekela indalo kunye nokuphila kwezindlu zabantu eziqhamuka kwezinto ezinceda ukusetshenziswa kwe-DBTO.
Kufuneka sicinge phambili ukubhala amagcindeyi esiphathelileyo asizange sikwazi ukusetyenziswa kwindawo yokusebenza kunye nezinto ezinisekisayo ezinzenzakalelayo ngoku sizizama ukukhathalisa i-DBTO, yasemva komntu wase-Lingshi amagcindeyi amathathu lwe-tin khloride izisebe zazo . Kuneenkinga kanjani ezikhoyo nezingca zikhe eziqhutywa ngezantsi. Ngokugcina, izinto zomlilo zazisetshenziswa amanqaku amaphushane amakhulu okuthi asebenzisa ukuze alihlinyene namandla angaphandle kokuthi akuyindlela engcono emfazweni. Zikhono amanye amagcindeyi, njengeplastiki, azisetshenziswa ngaphandle kokusetshenziswa nge-DBTO.
Ngokushesha, abantu ababangela bayenza ukuba kumele kube nenkinga elingekho lokuhlola, imigomo yakho yesiphumo sokuphatha kakhulu kumkhonto wesibayi kwaye nokuhlonipha kwesinye isixhobo.
Kwi-ndawo yokugqibela, ukuthi ngenxa yokuqala DBTO ungene ngokwesiphumo ukuba kungaba umsebenzi okuningi, amandla aqhathaniswa kwezilululo ezilandelayo nokuhlukeleko lwabantu licinga ukubhekiselelwa. Sebenzisa DBTO ngokulungileyo. UDBTO usebenziswayo ngamagoverinithi, indlela yesekhaya kunye neziciko zabantu - Zonke izintathu zethu ziyindlela lokusebenzisa kuyona ngokukhulu okanye ukufumana amandla ezindleni zazingaphambili. Ukutya kwaye ukwenza ukuphakamisa, zonke izintathu zethu zidinga ukubuyeleyo kwindawo yokuhlola lokuhlola izilimo zethu ngeentsimbi ezinhlanganekayo.
Siyithintorha thelwanisweni lokugcina lokungaphezulu lomunye wezinto eziphakemeleyo ze-tin ngesiqephu somdlalo wesintfo somkhulu weDibutyltin oxide. Abafundi abaninzi babethu nobukheli bokuhlanganiswa obunene baye kuqinisekiswa ukuthola amaxesha amahle okusetyenziswa ngezinto zokugcina ezikhethekileyo ezikhona ngokwesobizo kunye namanye amagcinyi ekhoyo kumalunye.
Ningxia Lingshi New Material Technology Co Ltd inqophiso e Ningxia Ningdong New Materials Park, efumanekayo isenzo esikhundleni sokuqala sokuthetha kwebutyltins, okwesibini nokwesithathu sooctyltins kunye noma amaphethanathi wezinyathelo zokugcina izicatulo. Ningxia Lingshi iyishushumano lesixhobo seNantong Haotai Products Chemicals Co Ltd kunye nomthengano wosixhobo wesimanje Shandong Lingshi New Material Co Ltd. Iziphrodyakhti zayo zisetshenziswa ngokupheleleyo kwiimfutshane, PVC, PU, uphawuli wokugcina izicatulo, ukusebenza komoya omncedisi kunye namanye amaxwebhu ekhona.
Kumxhantyeni wethu kukho imfanelo yezikathelo kanye nezilondolozo ezikhoyo zokuthuthukisa nokubhedlela kwebutile tin, i-Dibutyltin oxide kunye nembangiso yemizuzwana. Siqinisekisa ukuba umthengi ube ngumxholo omncane wendawo yesikaba, futhi umphathiso wokuThuthukiswa kunye nokuhlinzekela kwenqanawe yenqanawe yokuthuthukiswa ehlukanisayo lokusebenzela ukuthi siphindaphindi izinkinga ezifana nesiko, ukuze sihlaleke amaxwebhu okuthile, ayiqondisiyo, kunye nokungavamile lapho luhlaza.
Amanzi amabini lweDibutyltin oxide, ngomnyaka wokufundiswa nokulandelana, izilungiselelo zethu zaziqondisiwe ukuya kwiNtshonalanga, kodwa zizivele ukubuyela eLawulo neMerkheli nokuphela eAfrika ya Mzantsi nangoku e-Afrika, kunye nomunye omkhulu wezindawo eziningi. Ngoku sithi somthakathi wesithathu seshlulekile sekugcina lokuhlola kwaye singavamisela iNdawo yamaChina yesikhombisa soDibutyltin. Ngeminyaka yokuqala nokulandelana, izilungiselelo zethu zakhiwo ukuya kwiNtshonalanga, kodwa zizivele ukubuyela eLawulo, eMerkheli, eAfrika ya Mzantsi kunye nokuphela eAfrika ya Mzantsi kunye nokuba zizifundekayo kwindawo yokusetyenziswa esiphambili.
