Ukusetyenziswa kwezinto ezintsha ze-dichloromethane (DCM) okwangoku akujoliswanga ekwandiseni indima yayo yesiqhelo njengesinyibilikisi kodwa endaweni yoko kujoliswe “kwindlela yokuyisebenzisa nokuyiphatha ngokukhuselekileyo nangokufanelekileyo” kunye nokuhlola ixabiso layo elikhethekileyo kwiinkalo ezithile zobuchwepheshe obuphezulu.
I. Utshintsho lweNkqubo: Njenge "Sixhobo seNkqubo" esiLuhlaza nesiSebenzayo
Ngenxa yokuguquguquka kwayo okugqwesileyo, iqondo lokubila eliphantsi, kunye ne-solvency, i-DCM isetyenziswa njenge "nkqubo yoncedo" esebenzayo kubuchwepheshe obutsha endaweni yokuba yinxalenye yemveliso yokugqibela, ngaloo ndlela kunciphisa ukusetyenziswa kwayo kunye nokukhutshwa komoya.
1.Iarhente Esebenzayo Yokuguquguqula Imveliso yePolyolefin
Uyilo olutsha: Ezinye iinkampani ziphuhlise ubuchwepheshe obuzisa i-DCM njenge-arhente yokukrazula kwinkqubo yokudiliza izikrufu ze-polyolefins (umz., i-POE).
Inzuzo: I-DCM inciphisa ngempumelelo ukuxinana kwezinto kunye noxinzelelo oluncinci lomphezulu, iphucula kakhulu ukusebenza kakuhle kokususa ii-monomers ezisele kunye nee-volatible organic compounds. Le nkqubo ineemfuno eziphantsi zezixhobo kunye nokusebenza kakuhle kweendleko eziphezulu, okwenza ukuba isebenzise amandla kakuhle kwaye isebenze kakuhle xa ithelekiswa ne-vacuum ephezulu okanye i-devolatilization yendabuko.
2.I-Green Reaction Medium yokwenziwa kwamayeza
Utshintsho: Kwishishini lezemithi, i-DCM isanzima ukuyitshintsha ngokupheleleyo ngenxa yokuba inamandla okunyibilika. Utshintsho luxhomekeke ekuyidibaniseni neetekhnoloji zokuphendula eziphambili kunye neenkqubo zokuphinda kusetyenziswe ukuze kufezekiswe ukujikeleza kwegazi okuvaliweyo.
Ukusetyenziswa: Idityaniswe ne-continuous flow chemistry kunye ne-automated synthesis reactors, i-DCM solvent iphinda isetyenziswe kwaye icocwe ngexesha langempela ngeenkqubo zokubuyisela i-condensation ezikwi-intanethi ezakhelwe ngaphakathi, nto leyo enciphisa kakhulu ukusetyenziswa kwe-single-batch kunye neengozi zokuchatshazelwa.
II. Iteknoloji Ejikelezayo: Ukuphinda Usebenzise Ngokusebenzayo Nokuwohloka
Ukuphendula kwimithetho engqongqo yokusingqongileyo, kuye kwenziwa izinto ezintsha ezibalulekileyo kwi-DCM recycling kunye netekhnoloji yokulungisa izinto ezisetyenziswa ekupheleni kwepayipi.
1.Iteknoloji yeMechanical Vapor Recompression (MVR) esebenza kakuhle kumandla
Uyilo olutsha: Itekhnoloji yeMechanical Vapor Recompression (MVR) isetyenziselwa ukubuyisa umswakama wegesi yenkunkuma ye-DCM enoxinzelelo oluphezulu.
Inzuzo: Iicompressor zomphunga ze-DCM ezimelana nokugqwala nezizinzileyo kakhulu eziphuhliswe ziinkampani ezifana neChongtong Group zinokusebenzisa kwakhona amandla omphunga wesibini, zinciphise ukusetyenziswa kwamandla okusebenza ngokubanzi ngaphezulu kwe-40%, zivumela ukubuyiselwa kwe-DCM ngokufanelekileyo nangokungabizi kakhulu.
2.Iteknoloji yokubola kwe-Catalytic eSebenza kakuhle kakhulu kubushushu obuphantsi
Uyilo olutsha: Ukuphuhlisa ii-catalysts ezintsha ukuze zonakalise i-DCM ngokufanelekileyo nangokupheleleyo ibe zizinto ezingenabungozi kumaqondo obushushu aphantsi (70-120°C).
III. Izicelo ezikhethekileyo kwiMveliso ekumgangatho ophezulu kunye nezixhobo ezintsha
Kwezinye iindawo ezisemgangathweni ophezulu apho iimfuno zokusebenza kwezinto ziphezulu kakhulu, iipropati ezikhethekileyo zeDCM zenza ukuba ingabi sathathelwa indawo okwethutyana.
1.Ukucubungula Izinto zeFotoelectric
Ukusetyenziswa: Xa kulungiswa iiseli zelanga ze-perovskite, iileya ezikhupha ukukhanya ze-OLED, kunye nee-photoresists eziphezulu, kufuneka iifilimu ezincinci ezicocekileyo kakhulu. Ngenxa yokunyibilika kwayo okuhle kunye nendawo yokubilisa ephakathi kwiipolymers ezininzi ezisebenza kakuhle kunye neemolekyuli ezincinci, i-DCM ihlala yenye yezona zinyibilikisi zikhethwayo zelebhu kunye nokulungiselela ngokuchanekileyo okuncinci kweefilimu ezikumgangatho ophezulu.
2.Ukukhupha ulwelo olungaphezulu kwe-Supercritical
Ukusetyenziswa: I-DCM ingasetyenziswa njengesiguquli okanye isinyibilikisi esidibeneyo kunye ne-CO₂ ebaluleke kakhulu ekukhupheni ngempumelelo nangokukhetha kakhulu iikhompawundi ezithile (umz., ii-alkaloids, iioyile ezibalulekileyo) ezivela kwiimveliso zendalo. Ukusebenza kwayo kakuhle kokukhupha kunye nokukhetha kungaphezulu kwezo zolwelo lwe-CO₂ olucocekileyo olubaluleke kakhulu.
IV. Isishwankathelo kunye neMbono
Ngokubanzi, usetyenziso olutsha lwe-dichloromethane luhamba ngeendlela ezimbini ezicacileyo:
Utshintsho lweNkqubo: Ukutshintsha ukusuka "ekusetyenzisweni okuvulekileyo" ukuya "ekujikelezeni okuvaliweyo," kusetyenziswa njengendlela yokusebenza esebenzayo edibene netekhnoloji yokuhlaziya ephucukileyo, injongo yokugqibela kukunciphisa ukusetyenziswa okunetha kunye nokukhutshwa komoya ongcolileyo kwindalo esingqongileyo.
Utshintsho lweXabiso: Ukugcina indawo yayo kwiinkalo ezithile zobuchwepheshe obuphezulu apho kunzima ukuyitshintsha (umz., amayeza aphezulu, izixhobo zombane) ngokudibanisa nezinye iteknoloji eziphambili ukuze kusetyenziswe ixabiso layo elikhethekileyo.
Uphuhliso lwexesha elizayo luya kuqhubeka lujikeleza kumxholo othi “ukhuselekile, uluhlaza, kwaye usebenza kakuhle.” Kwelinye icala, uphando malunga nezinyibilikisi ezingezinye ezinobuthi obuphantsi luya kuqhubeka, ngelixa kwelinye icala, ubuchwepheshe bokuphucula ukusetyenziswa kunye nokulahla i-DCM buya kuqhubeka bukhula, bunciphisa iingozi kwiimeko apho ukusetyenziswa kwayo kungenakuphepheka.
