I-Methylene Chloride (MC), isinyibilikisi esiguquguqukayo esisetyenziswa ngokubanzi kumayeza, i-adhesives, kunye ne-aerosol formulations, iqhuba utshintsho olubalulekileyo kusetyenziso lwaso lwemizi-mveliso kunye nenkangeleko yolawulo. Inkqubela phambili yakutsha nje ekusebenzeni kakuhle kwemveliso, iiprothokholi zokhuseleko lokusingqongileyo, kunye nolunye uphando lokunyibilikisa luyila ngokutsha indlela le khemikhali ebonwa ngayo kwaye isetyenziswa kuwo wonke amakhonkco obonelelo lwehlabathi.
1. Ukuphumelela kwiiNkqubo ezivaliweyo zokuSebenza ngokutsha
Indlela ye-groundbreaking yokubuyisela kunye nokusebenzisa kwakhona i-dichloromethane kwiinkqubo zokuvelisa ifumene i-traction ngo-2023. Iphuhliswe yi-European research consortium, le nkqubo ivaliweyo isebenzisa iteknoloji ye-adsorption ephezulu ukuze ibambe kwaye ihlambulule imiphunga ye-MC ekhutshwe ngexesha lokuvelisa i-coating. Izilingo zangaphambili zibonisa i-92% yezinga lokubuyisela, ukunciphisa kakhulu ukusetyenziswa kwezinto eziluhlaza kunye nokukhutshwa.
Itekhnoloji idibanisa uhlolo oluqhutywa yi-AI ukuze kwandiswe imijikelo yokusetyenziswa kwakhona kwe-solvent, iqinisekisa ukuthotyelwa kwemida engqongqo yokuvezwa kwindawo yokusebenza. Amashishini afana ne-polycarbonate yokuvelisa kunye nokucoca icandelo le-elektroniki alinga le nkqubo, ehambelana ne-International Council of Chemical Associations '(ICCA) 2030 ekujoliswe kuyo kuqoqosho lwesetyhula.
2. Ukuqiniswa kweMimiselo yeHlabathi kwi-MC Emissions
Imibutho elawulayo iqinisa ukuphononongwa kweMethylene Chloride ngenxa yokuncipha kwayo kwe-ozone (ODP) kunye nobungozi bezempilo emsebenzini. NgoSeptemba ka-2023, i-Arhente yeMichiza yaseYurophu (i-ECHA) indulule izilungiso kwimimiselo ye-REACH, egunyazisa ukulandelwa kwexesha lokwenyani lokukhutshwa kwezixhobo ezisebenzisa ngaphezu kweetoni ezingama-50 ze-MC ngonyaka. Imigaqo ikwafuna ukuba kufakwe iimvavanyo endaweni yezicelo ezingabalulekanga nge-Q2 2024.
Ngaxeshanye, i-Arhente yoKhuseleko lweNdalo yase-US (i-EPA) iqalise ukuphononongwa kwesimo se-MC phantsi koMthetho woLawulo lweZinto eziyityhefu (TSCA), kunye neziphumo zokuqala ezibonisa ukuba imida yoxinaniso ye-airborne kwindawo yokusebenza-enokuthi yehlise umda ukusuka kwi-25 ppm ukuya kwi-10 ppm. La manyathelo ajonge ukujongana neenkxalabo ezikhulayo malunga neziphumo ze-neurological zexesha elide phakathi kwabasebenzi bemizi-mveliso.
3. ICandelo loShishino Lamkela iindlela ezizezinye eziGreener
Umzi-mveliso wamachiza, umthengi omkhulu we-Methylene Chloridefor crystallization yechiza kunye nokutsalwa, ukhawulezisa ulingo lwezinyibilikisi ezisekwe kwibhayoloji. Uphononongo olujongwe ngontanga olupapashwe kwi-*Green Chemistry* (Agasti 2023) luqaqambise izinyibilikisi eziphuma kwi-limonene njengotshintsho lwe-MC olusebenzayo kwi-API (izithako ezisebenzayo zamayeza) udityaniso, ukuzuza izivuno ezithelekisekayo nge-80% yeeprofayili zetyhefu ezisezantsi.
Ngelixa ukwamkelwa komntwana ongamzalanga abe ngowakho kuhlala kusanda ngenxa yemingeni yozinzo, inkuthazo elawulayo phantsi koMthetho wokuNcitshiswa kwexabiso lokunyuka kwamaxabiso e-US zibonelela ngenkxaso-mali yezityalo ezilingwayo ezizinikele ekwandiseni ezi ndlela zihlukileyo. Abahlalutyi baqikelela i-15-20% yokunciphisa imfuno ye-MC kwi-pharma ngo-2027 ukuba iindlela zangoku ze-R&D ziyaqhubeka.
4. Ukuqhubela phambili kwi-MC Risk Mitigation Technologies
Ulawulo lobunjineli olutsha lunciphisa iingozi ezinxulumene neMC. Iqela lophando laseMntla Melika lisanda kutyhila inkqubo ye-nanoparticle-based filtration system ebolisa i-MC eseleyo kwimijelo yamanzi amdaka ibe yimveliso engeyiyo inetyhefu efana ne-chloride ion kunye ne-carbon dioxide. Inkqubo ye-photocatalytic, eyenziwa sisibane esine-UV esine-eneji ephantsi, ifikelela kwi-99.6% yokuthotywa komgangatho kwaye idityaniswe kumaziko okucoca amanzi amdaka ngemichiza.
Ukongeza, izixhobo zokukhusela zomntu ezikwisizukulwana esilandelayo (i-PPE) ezine-graphene-enhanced respirators zibonise ukusebenza kwe-98% ekuthinteleni umphunga we-MC ngexesha lemisebenzi ephezulu yokuvezwa njengokuhluthwa kwepeyinti. Olu phuhliso lungqamana nezikhokelo ezihlaziyiweyo ze-OSHA ezigxininisa ulawulo lokuvezwa olunamanqanaba kubaphathi be-MC.
5. Uzinzo-Eqhutywa uShift kwiMarike
Ngaphandle kwendima yayo eyendeleyo, i-Methylene Chloride ijongene noxinzelelo olukhulayo oluvela kwi-ESG (yendalo, ezentlalo, nolawulo) iindlela zotyalo-mali. Uphando luka-2023 olwenziwa ngumhlalutyi ophambili weshishini lemichiza luveze ukuba i-68% yabavelisi abasezantsi ngoku babeka phambili ababoneleli ngezicwangciso eziqinisekisiweyo zokunciphisa ukukhutshwa kwe-MC. Lo mkhwa ukhuthaza ukuqalwa kwezinto ezintsha kwiziseko zoncedo ezinyibilikayo kunye neendlela zokuvelisa i-bio-hybrid.
Ngokucacileyo, iprojekthi yokulinga kuMzantsi-mpuma we-Asia idibanise ngempumelelo i-MC isebenzisa i-methane chlorination enikwa amandla ahlaziyekayo, ukusika i-carbon footprint yemveliso ngama-40%. Ngelixa imiceli mngeni yokuncipha isekhona, amanyathelo anjalo agxininisa icandelo leekhemikhali kwipivot kwi-decarbonized solvent ecosystems.
Ukuqukumbela: Ukulungelelanisa usetyenziso kunye noxanduva
Njengoko i-Methylene Chloride ihlala iyimfuneko kwizicelo ezibalulekileyo, ugqaliselo lweshishini kutshintsho oluzinzileyo kunye nokuthotyelwa kwemithetho kuyaqina. Ukudibana kweenkqubo zokubuyisela umva, ezinye iindlela ezikhuselekileyo, kunye nemigaqo-nkqubo ephuhlayo iya kuchaza indima ye-MC kwikamva elinekhabhoni ephantsi. Abachaphazelekayo kulo lonke isixokelelwano sexabiso kufuneka ngoku bajonge esi sigaba soguqulo-apho ukusebenza ngokufanelekileyo kunye nolawulo lokusingqongileyo luhlangana-ukukhusela ukusebenza kwexesha elide.
