Methylene Chloride chinhu chakakosha muindasitiri inonyungudutsa, uye indasitiri yekusimudzira uye tsvagiridzo yesainzi inyaya dzinotariswa zvakanyanya. Chinyorwa ichi chinotsanangura zvichangobva kuitika kubva pazvinhu zvina: chimiro chemusika, masimba ekutonga, mafambiro emitengo, uye kufambira mberi kwetsvakiridzo yesainzi.
Market Structure: Musika wepasi rose wakatarisana zvakanyanya, nevagadziri vatatu vepamusoro (seJuhua Group, Lee & Man Chemical, uye Jinling Group) vakabata chikamu chemusika chakabatanidzwa chinosvika makumi matatu nematanhatu%. Dunhu reAsia-Pacific ndiro musika mukuru, unoverengera 75% yemugove.
Regulatory Dynamics:Sangano reUS Environmental Protection Agency (EPA) rakapa mutemo wekupedzisira pasi pemutemo weToxic Substances Control Act (TSCA) unorambidza kushandiswa kwemethylene chloride muzvigadzirwa zvevatengi zvakaita semapendi ekubvisa pendi uye kuisa zvirango zvakasimba pakushandiswa kwemaindasitiri.
Mutengo Mafambiro: Muna Nyamavhuvhu 2025, nekuda kwehuwandu hwekushanda kweindasitiri inotungamira kune yakawandisa, pamwe nekunze-mwaka wekudiwa uye kushomeka kwekutenga kufarira kudzika, mitengo kubva kune vamwe vagadziri yakadzika pasi pe2000 RMB/ton mamaki.
Trade Situation:Kubva muna Ndira kusvika Chivabvu 2025, kuChina kutengesa kunze kwemethylene chloride kwakawedzera zvakanyanya (gore-pa-gore +26.1%), yakanangana neSoutheast Asia, India, uye mamwe matunhu, ayo anobatsira kudzikisira kumanikidzwa kwekupa mudzimba.
Miganho muIzvino Tekinoroji Research
Mundima yekutsvagisa sainzi, zvidzidzo zvemethylene chloride uye zvine hukama nemakomisheni zviri kufambira mberi zvichienda kune yakasvibira uye inoshanda nzira. Heano maitiro akati wandei akakosha:
Green Synthesis nzira:Chikwata chekutsvagisa kubva kuShandong University of Technology chakaburitsa chidzidzo chitsva muna Kubvumbi 2025, vachikurudzira pfungwa nyowani ye "magnetic driven redox." Iyi tekinoroji inoshandisa inotenderera yemagineti kugadzira iyo induced electromotive simba mune simbi conductor, nekudaro ichityaira kuita kwemakemikari. Ichi chidzidzo chakaratidza kushandiswa kwekutanga kweiyi zano mukushandura simbi catalysis, kubudirira kubudirira kudzoreredza muchinjiko-kubatana kweiyo isingaite reactive aryl chlorides ine alkyl chlorides. Izvi zvinopa nzira itsva yekumisikidza inert kemikari bond (senge C-Cl bond) pasi pemamiriro akapfava, ane mukana wekushandisa kwakafara.
Separation Process Optimization:Mukugadzirwa kwemakemikari, kupatsanurwa uye kucheneswa ndiwo matanho anokosha ekushandisa simba. Imwe tsvagiridzo yakanangana nekugadzira michina mitsva yekuparadzanisa maitiro musanganiswa kubva kumethylene chloride synthesis. Tsvagiridzo iyi yakaongorora kushandisa methanol seyakazviburitsa kuparadzanisa misanganiswa yedimethyl ether-methyl chloride ine yakaderera kudzikama, ichivavarira kuvandudza kupatsanurwa kwakanaka uye optimize maitiro paramita.
Ongororo Yezvishandiso muNew Solvent Systems:Kunyangwe isingabatanidzi zvakananga methylene chloride, chidzidzo chezvakadzika eutectic solvents (DES) chakaburitswa muPMC muna Nyamavhuvhu 2025 chakakosha. Ichi chidzidzo chakapa nzwisiso yakadzama yemhando yekudyidzana kwema molecular mukati mezvigadziriso zvinonyungudutsa. Kufambira mberi muhunyanzvi hwekunyungudutsa kwakasvibira kwakadai kunogona, nekufamba kwenguva, kupa mikana mitsva yekutsiva mamwe echinyakare anokanganisa organic solvents, kusanganisira methylene chloride.
Muchidimbu, iyo methylene chloride indasitiri parizvino iri munguva yekuchinja inoratidzwa nemikana uye nematambudziko.
Matambudzikozvinonyanya kuratidzwa mukuwedzera kuomesera mirau yezvakatipoteredza (kunyanya mumisika yakaita seEurope neUS) uye mhedzisiro yekuda kuderera mune dzimwe nzvimbo dzechinyakare dzekushandisa (senge pendi strippers).
Mikana, zvisinei, zviri mukudiwa kwakasimba mukati mezvikamu umo zvinotsiva zvakakwana zvisati zvawanikwa (zvakadai semishonga nemakemikari synthesis). Panguva imwe cheteyo, kuenderera mberi kwekugadzirisa kwemaitiro ekugadzira uye kuwedzera kwemisika yekunze kuri kupawo simba rekusimudzira indasitiri.
Kubudirira kweramangwana kunotarisirwa kutsamira zvakanyanya kune yakakwirira-kuita, yakakwirira-kuchena zvigadzirwa zvehunyanzvi uye hunyanzvi hwetekinoroji hunoenderana nemisimboti yegirinhi chemistry.
