Methylene Chloride ni umuti w'ingenzi mu nganda, kandi iterambere ry'inganda n'ubushakashatsi bwa siyansi ni ibintu bigomba kwitabwaho cyane. Iyi nkuru izagaragaza iterambere ryayo riheruka mu ngingo enye: imiterere y'isoko, imiterere y'amategeko, ibiciro bihagaze, n'iterambere riheruka ry'ubushakashatsi bwa siyansi.
Imiterere y'Isoko: Isoko ry’isi ryibanda cyane, aho abakora ibicuruzwa bitatu bya mbere (nka Juhua Group, Lee & Man Chemical, na Jinling Group) bafite isoko rya hafi 33%. Akarere ka Aziya na Pasifika ni ko gafite isoko rinini, kagize hafi 75% by’imigabane.
Imiterere y'amategeko:Ikigo gishinzwe kurengera ibidukikije muri Amerika (EPA) cyashyizeho itegeko rya nyuma rigenga kurwanya uburozi (TSCA) ribuza ikoreshwa rya methylene chloride mu bicuruzwa bikoreshwa n'abantu nka za rangi ndetse rigashyiraho amategeko akaze ku ikoreshwa ry'inganda.
Ibiciro bihagaze: Muri Kanama 2025, bitewe n’uko imikorere y’inganda yari iri hejuru bigatuma habaho ibicuruzwa byinshi, hamwe n’uko abantu batari basanzwe bakenera ibicuruzwa mu gihe cy’ikiruhuko cy’akazi ndetse n’ubushake buke bwo kugura ibicuruzwa, ibiciro by’inganda zimwe na zimwe byagabanutse munsi ya 2000 RMB/toni.
Imiterere y'Ubucuruzi:Kuva muri Mutarama kugeza muri Gicurasi 2025, ibicuruzwa bya methylene chloride byoherezwa mu mahanga mu Bushinwa byariyongereye cyane (umwaka ku wundi +26.1%), ahanini bikaba byaragenewe Aziya y'Amajyepfo y'Uburasirazuba, Ubuhinde, n'utundi turere, ibi bikaba bifasha kugabanya igitutu cy'ibicuruzwa byo mu gihugu.
Imbibi mu bushakashatsi bugezweho bw'ikoranabuhanga
Mu rwego rw'ubushakashatsi bwa siyansi, inyigo kuri methylene chloride n'ibindi binyabutabire bifitanye isano ziri gutera imbere zigana ku cyerekezo cyiza kandi gitanga umusaruro mwiza. Dore ibyerekezo byinshi by'ingenzi:
Uburyo bwo gukora ibara ry'icyatsi kibisi:Itsinda ry’abashakashatsi bo muri Kaminuza ya Shandong y’Ikoranabuhanga ryasohoye ubushakashatsi bushya muri Mata 2025, butanga igitekerezo gishya cya "redox ikoresha ingufu za rukuruzi." Ubu ikoranabuhanga rikoresha imbaraga za rukuruzi zizenguruka kugira ngo rikore imbaraga za electromotive zikomoka ku cyuma gitwara amashanyarazi, bityo bigatera ingaruka za chemical reactions. Ubu bushakashatsi bwabaye ubwa mbere bukoreshwa muri ubu buryo mu guhindura ibyuma, bugera ku buryo bwo kugabanya imikoranire ya aryl chloride zidakora neza na alkyl chloride. Ibi bitanga inzira nshya yo gukora imigozi ya chemical idafite ingufu (nk'imigozi ya C-Cl) mu bihe byoroheje, kandi ishobora gukoreshwa mu buryo bwagutse.
Gutunganya inzira zo gutandukanya:Mu gukora imiti, gutandukanya no gutunganya ni intambwe z'ingenzi zikoresha ingufu. Ubushakashatsi bumwe bwibanda ku guteza imbere igikoresho gishya cyo gutandukanya imvange z'ibisubizo n'ikorwa rya methylene chloride. Ubu bushakashatsi bwasuzumye ikoreshwa rya methanol nk'ikintu cyikuramo mu gutandukanya imvange za dimethyl ether-methyl chloride zifite imihindagurikire mike, hagamijwe kunoza imikorere y'imvange no kunoza ibipimo by'imikorere.
Gushakisha Porogaramu muri Sisitemu Nshya z'Ibishongesho:Nubwo idafite methylene chloride mu buryo butaziguye, inyigo ku misombo y’amazi yimbitse (DES) yasohotse muri PMC muri Kanama 2025 ni ingenzi cyane. Ubu bushakashatsi bwatanze ubumenyi bwimbitse ku miterere y’imikoranire ya molekile mu buryo bw’imishongi. Iterambere muri ubwo buryo bw’ikoranabuhanga mu gushonga kw’icyatsi rishobora, mu gihe kirekire, gutanga amahirwe mashya yo gusimbuza misombo imwe n’imwe gakondo ihindagurika, harimo na methylene chloride.
Muri make, inganda za methylene chloride muri iki gihe ziri mu gihe cy'inzibacyuho kirangwa n'amahirwe n'imbogamizi.
Imbogamizibigaragarira cyane cyane mu mategeko agenga ibidukikije (cyane cyane mu masoko nka Burayi na Amerika) ndetse n'igabanuka ry'ibikenewe mu bice bimwe na bimwe bisanzwe bikoreshwa (nk'abakuraho irangi).
Amahirweicyakora, biri mu busabe burambye mu nzego aho ibisimbura bitunganye bitaraboneka (nk'imiti n'ibinyabutabire). Muri icyo gihe, kunoza ibikorwa by'umusaruro no kwagura amasoko yo kohereza ibicuruzwa mu mahanga nabyo bitanga imbaraga mu iterambere ry'inganda.
Biteganijwe ko iterambere ry’ejo hazaza rizashingira cyane ku bicuruzwa byihariye bifite imikorere myiza kandi bifite isuku nyinshi hamwe n’udushya mu ikoranabuhanga dujyanye n’amahame y’ubutabire bw’ibidukikije.
