Methylene Chloride (MC), chinhu chinonyungudutsa chinoshandiswa zvakanyanya mumishonga, zvinonamira, uye aerosol formulations, chiri kuchinja zvakanyanya mukushandiswa kwayo mumaindasitiri uye mumamiriro ekutonga. Kufambira mberi munguva pfupi yapfuura mukubudirira kwekugadzira, mitemo yekuchengetedza zvakatipoteredza, uye tsvakiridzo yezvimwe zvinonyungudutsa zviri kuchinja patsva maonerwo uye mashandisirwo ekemikari iyi muzvikamu zvepasi rose zvekupa.
1. Kubudirira muClosed-Loop Recycling Systems
Nzira itsva yekudzoreredza nekushandisazve dichloromethane mukugadzira yakawana simba muna 2023. Yakagadzirwa nesangano rekutsvagisa reEurope, iyi sisitimu yakavharwa inoshandisa matekinoroji epamusoro ekubata nekuchenesa utsi hweMC hunobuda panguva yekugadzira coating. Miedzo yekutanga inoratidza kuti 92% yekudzoreredza, zvichideredza zvakanyanya kushandiswa kwezvinhu zvakabikwa uye utsi hunobuda.
Tekinoroji iyi inobatanidza kutarisa kunotungamirirwa neAI kuti ivandudze mashandiro ekushandisazve solvent, ichiva nechokwadi chekuti mitemo yekusangana nenzvimbo yebasa inotevedzwa. Maindasitiri akadai sekugadzira polycarbonate uye kuchenesa zvikamu zvemagetsi ari kuedza hurongwa uhwu, hunoenderana nezvinangwa zvehupfumi zveInternational Council of Chemical Associations (ICCA) 2030.
2. Kusimbisa Mitemo Yepasi Pose Pakurwisa Kuburitswa Kwemhepo Mumhepo
Masangano anotonga ari kuwedzera kuongororwa kweMethylene Chloride nekuda kwekugona kwayo kupera kweozone (ODP) uye njodzi dzehutano hwebasa. MunaGunyana 2023, European Chemicals Agency (ECHA) yakakurudzira shanduko kumitemo yeREACH, ichiraira kuteverwa kwekubuda kwemhepo panguva chaiyo kwezvivako zvinoshandisa matani anopfuura makumi mashanu eMC pagore. Mitemo iyi inodawo kuongororwa kwekutsiviwa kwezvishandiso zvisiri zvakakosha panosvika Q2 2024.
Panguva imwe chete, US Environmental Protection Agency (EPA) yakatanga ongororo yemamiriro eMC pasi peToxic Substances Control Act (TSCA), neongororo dzekutanga dzichiratidza kuti miganhu yekuwanda kwevanhu munzvimbo yebasa iri mumhepo—zvichida kuderedza chiyero kubva pa25 ppm kusvika pa10 ppm. Matanho aya anonangana nekugadzirisa kushushikana kuri kuwedzera pamusoro pemigumisiro yenguva refu yetsinga pakati pevashandi vemaindasitiri.
3. Bazi reMishonga Rinotora Dzimwe Nzira Dzine Ruzivo Rwakanaka
Indasitiri yemishonga, iyo inonyanya kushandisa Methylene Chloride pakugadzira uye kubvisa mishonga, iri kukurumidza kuyedza mishonga inonyungudutsa inobva kuzvinhu zvipenyu. Chidzidzo chakaongororwa nevezera rayo chakaburitswa mu *Green Chemistry* (Nyamavhuvhu 2023) chakaratidza kuti mishonga inonyungudutsa inobva kulimonene inogona kushandiswa kutsiva MC mukugadzirwa kweAPI (active pharmaceutical ingredient), zvichiita kuti pave negoho rakafanana ne80% ine chepfu yakaderera.
Kunyange hazvo kugamuchirwa kwemishonga iyi kuchiramba kuri kuwedzera nekuda kwematambudziko ekugadzikana kwemishonga iyi, zvinokurudzira zviri mumutemo pasi peUS Inflation Reduction Act zviri kupa mari kumafekitori ekuedza akazvipira kuwedzera dzimwe nzira idzi. Vaongorori vanofanotaura kudzikira kwe15-20% mukudiwa kwemishonga kubva kumishonga panosvika 2027 kana maitiro eR&D aripo akaramba aripo.
4. Kufambira Mberi muMatekinoroji eKuderedza Njodzi eMC
Kudzora mainjiniya matsva kuri kuderedza njodzi dzine chekuita neMC. Chikwata chekutsvagisa chekuNorth America munguva pfupi yapfuura chakaburitsa sisitimu yekusefa yakavakirwa pa nanoparticle iyo inoora MC yakasara mumvura yakasviba ichiita zvinhu zvisina chepfu zvakaita se chloride ions ne carbon dioxide. Maitiro e photocatalytic, anoshandiswa nechiedza cheUV chine simba shoma, anowana kushanda zvakanaka kwe99.6% uye ari kubatanidzwa muzvivakwa zvekurapa mvura yakasviba zvine makemikari.
Pamusoro pezvo, michina yekudzivirira munhu yechizvarwa chinotevera (PPE) ine marespirator anowedzerwa negraphene yakaratidza kushanda zvakanaka kwe98% mukudzivirira utsi hweMC panguva yemabasa anoshandiswa zvakanyanya sekubvisa pendi. Izvi zvinoenderana nemirairo yakagadziridzwa yeOSHA inosimbisa kudzora kusvibiswa kweganda kune vanobata MC.
5. Kuchinja Kwemusika Kunokonzerwa Nekuchengetedza Nguva Dzebasa
Pasinei nebasa rayo rakasimba, Methylene Chloride inotarisana nekumanikidzwa kuri kuwedzera kubva kuESG (zvenharaunda, zvemagariro evanhu, zvehutongi). Ongororo yakaitwa muna 2023 nenyanzvi yekuongorora makemikari yakaratidza kuti 68% yevagadziri vepasi pemvura ikozvino vari kukoshesa vatengesi vane zvirongwa zvakavimbiswa zvekuderedza utsi hweMC. Maitiro aya ari kukurudzira hunyanzvi mukugadzirisa zvivakwa zve solvent uye nzira dzekugadzira bio-hybrid.
Zvinonyanya kukosha kuti, chirongwa chekuedza kuSoutheast Asia chakabudirira kugadzira MC ichishandisa methane chlorination inotsigirwa nesimba rinogona kushandiswazve, zvichideredza simba rekugadzira kabhoni ne40%. Kunyange hazvo matambudziko ekukura achiripo, zvirongwa zvakadaro zvinosimbisa chinangwa chechikamu chemakemikari kune ecosystems ye solvent yakabviswa kabhoni.
Mhedziso: Kuenzanisa Kushandiswa Kwebasa uye Mutoro
Sezvo Methylene Chloride ichiramba yakakosha pakushandiswa kwakakosha, kutarisisa kweindasitiri pakuvandudza zvinhu zvitsva uye kutevedzera mitemo kuri kuwedzera. Kubatana kwemaitiro ekugadzirisa zvinhu matsva, dzimwe nzira dzakachengeteka, uye marongero ari kuchinja zvichatsanangura basa reMC mune ramangwana risina kabhoni yakawanda. Vane chekuita nehurongwa hwezvinhu vanofanirwa kufamba nechikamu chino chekuchinja—uko kushanda zvakanaka uye kuchengetedzwa kwezvakatipoteredza zvinosangana—kuti vawane mukana wekugara kwenguva refu.
