Methylene Chloride chinhu chakakosha muindasitiri, uye kukura kwayo muindasitiri nekutsvagisa kwesainzi zvinhu zvinofanirwa kutariswa zvakanyanya. Chinyorwa chino chichatsanangura kufambira mberi kwayo kwazvino kubva pazvinhu zvina: chimiro chemusika, mafambiro emitemo, mafambiro emitengo, uye kufambira mberi kwekutsvaga kwesainzi kwazvino.
Maumbirwo eMusika: Musika wepasi rose wakanyanya kuwanda, nevatengesi vatatu vepamusoro (vakaita seJuhua Group, Lee & Man Chemical, neJinling Group) vane musika wepakati weinenge 33%. Dunhu reAsia-Pacific ndiro musika mukuru, uchitora chikamu chinosvika 75% chemugove.
Maitiro Ekutonga:Sangano reUS Environmental Protection Agency (EPA) rakaburitsa mutemo wekupedzisira pasi peToxic Substances Control Act (TSCA) unorambidza kushandiswa kwemethylene chloride muzvigadzirwa zvevatengi zvakaita semapendi anobvisa pendi uye kuisa mitemo yakasimba pakushandiswa kwemaindasitiri.
Mafambiro Emitengo: Muna Nyamavhuvhu 2025, nekuda kwehuwandu hwekushanda kwakanyanya muindasitiri zvichikonzera kuwanikwa kwakakwana, pamwe chete nekushaikwa kwezvinodiwa panguva yekuzorora uye kusada kutenga zvakawanda, mitengo yevamwe vagadziri yakaderera pasi pe2000 RMB/ton mark.
Mamiriro Ekutengeserana:Kubva muna Ndira kusvika muna Chivabvu 2025, kutengeswa kwemethylene chloride neChina kwakawedzera zvakanyanya (gore negore +26.1%), zvakanyanya kuenda kuSoutheast Asia, India, nedzimwe nzvimbo, izvo zvinobatsira kuderedza kumanikidzwa kwezvekushandisa mudzimba.
Miganhu muKutsvagurudza Kwetekinoroji Kwemazuva Ano
Munyaya yekutsvagisa kwesainzi, zvidzidzo pamethylene chloride nezvimwe zvinhu zvine chekuita nazvo zviri kufambira mberi kuenda kunzvimbo dzakasvibira uye dzinoshanda zviri nani. Heano mamwe maitirwo akakosha:
Nzira dzekugadzira zvinhu zveGreen:Chikwata chekutsvagisa kubva kuShandong University of Technology chakaburitsa chidzidzo chitsva muna Kubvumbi 2025, chichipa pfungwa itsva ye "redox inotungamirwa nemagineti." Iyi tekinoroji inoshandisa simba remagineti rinotenderera kugadzira simba remagetsi rinokonzereswa musimbi, nokudaro zvichitungamira maitiro emakemikari. Chidzidzo ichi chakaratidza kushandiswa kwekutanga kweiyi nzira mukuchinja kwesimbi catalysis, zvichibudirira kuita kuti pave nekubatana kwe aryl chloride dzisina simba ne alkyl chloride. Izvi zvinopa nzira itsva yekuvandudza ma inert chemical bonds (akadai seC-Cl bonds) mumamiriro ekunze asina kusimba, ane mukana wekushandiswa zvakanyanya.
Kugadzirisa Maitiro Ekuparadzanisa:Mukugadzirwa kwemakemikari, kupatsanura nekuchenesa ndiwo matanho akakosha anoshandisa simba. Imwe tsvakurudzo inotarisa pakugadzira mudziyo mutsva wekupatsanura musanganiswa we reaction kubva mukugadzirwa kwemethylene chloride. Tsvagiridzo iyi yakaongorora kushandisa methanol sechinhu chinoburitsa musanganiswa we dimethyl ether-methyl chloride ine volatility yakaderera, ichivavarira kuvandudza kushanda zvakanaka kwekupatsanura uye kugadzirisa ma process parameters.
Kuongorora Mashandisirwo muNew Solvent Systems:Kunyangwe zvisiri kubatanidza zvakananga methylene chloride, chidzidzo pamusoro pe deep eutectic solvents (DES) chakaburitswa muPMC muna Nyamavhuvhu 2025 chakakosha zvikuru. Chidzidzo ichi chakapa ruzivo rwakadzama pamusoro pehunhu hwekudyidzana kwemamorekuru mukati memasisitimu ekunyungudutsa. Kufambira mberi mune matekinoroji e green solvent akadaro, nekufamba kwenguva, kunogona kupa mikana mitsva yekutsiva mimwe makemikari echinyakare anonyungudutsa, kusanganisira methylene chloride.
Muchidimbu, indasitiri yemethylene chloride parizvino iri munguva yekuchinja ine mikana nematambudziko.
Matambudzikozvinonyanya kuratidzwa mumitemo yezvakatipoteredza yakanyanya kuomarara (kunyanya mumisika yakaita seEurope neUS) uye kudzikira kwezvinodiwa munzvimbo dzimwe dzekushandisa (senge mapendi ekupukuta).
MikanaZvisinei, zviri mukudiwa kuri kuramba kuripo mukati mezvikamu uko zvinhu zvinotsiva zvakakwana zvisati zvawanikwa (zvakadai semishonga uye kugadzirwa kwemakemikari). Panguva imwe chete, kugadziriswa kuri kuramba kuchiitwa kwemaitiro ekugadzira uye kuwedzera kwemisika yekutengesa kunze kwenyika zviri kupawo simba rekusimudzira indasitiri.
Kubudirira mune ramangwana kunotarisirwa kuti kuenderere mberi nezvigadzirwa zvepamusoro-soro, zvakachena uye hunyanzvi hwetekinoroji hunoenderana nemisimboti yemakemikari akasvibirira.
