Mashandisirwo matsva e dichloromethane (DCM) parizvino haana kunyanya kutarisisa pakuwedzera basa rayo rechinyakare semushonga unonyungudutsa asi pane "kuti ungaishandisa sei zvakachengeteka uye zvinobudirira" uye kuongorora kukosha kwayo kwakasiyana muminda chaiyo yetekinoroji yepamusoro.
I. Kugadzira Maitiro: Se "Chishandiso Chekugadzira" Chine Ruzivo Rwakanaka uye Chinoshanda
Nekuda kwekushanduka kwayo kwakanaka, kudzika kwekubikira, uye kugadzikana kwayo, DCM inoshandiswa se "process aid" inoshanda muhunyanzvi hutsva kwete sechikamu chechigadzirwa chekupedzisira, nokudaro ichideredza kushandiswa kwayo kwese uye kuburitswa kwemhepo.
1.Mushonga Unobvisa Simba Unoshanda weKugadzira Polyolefin
Kugadzira zvinhu zvitsva: Mamwe makambani akagadzira matekinoroji anoisa DCM sechinhu chinobvisa zvinhu mukubvisa sikuruu kwema polyolefins (semuenzaniso, POE).
Zvakanakira: DCM inoderedza kusimba kwezvinhu uye kumanikidzwa kwenzvimbo, zvichivandudza zvakanyanya kushanda kwekubvisa mamonomers akasara uye makemikari anoshanduka-shanduka. Maitiro aya ane zvinodiwa zvishoma zvemidziyo uye anodhura zvakanyanya, zvichiita kuti ishandise simba shoma uye ishande zvakanaka kana tichienzanisa nekushandiswa kwevacuum yakawanda kana kupisa kwakanyanya.
2.Green Reaction Medium yekugadzirwa kwemishonga
Kugadzira Zvitsva: Muindasitiri yemishonga, DCM ichiri yakaoma kutsiva zvachose nekuda kwesimba rayo guru rekugona kuigadzirisa. Kugadzira zvitsva kuri mukuisanganisa netekinoroji yepamusoro yemhinduro uye maitiro ekudzokorodza kuti iwane kutenderera kweropa kwakavharwa.
Mashandisirwo: Yakabatana ne continuous flow chemistry uye automated synthesis reactors, DCM solvent inodzokororwazve uye inocheneswa kuburikidza ne-built-in online condensation recovery systems, zvichideredza zvakanyanya kushandiswa kwe-single-batch uye njodzi dzekusangana.
II. Tekinoroji Yakatenderera: Kudzokorodza uye Kuora Zvinobudirira
Mukupindura mitemo yakaoma yezvakatipoteredza, kwakaitwa zvinhu zvitsva zvikuru mukushandisazve DCM uye matekinoroji ekugadzirisa zvinhu zveDCM.
1.Tekinoroji yeKudzoreredza Utsi hweMichina Inoshanda Simba Risingapfuure Simba (MVR)
Kugadzira: Tekinoroji yeMechanical Vapor Recompression (MVR) inoshandiswa kudzoreredza kudziya kwemhepo kubva mugasi reDCM rine huwandu hwakawanda hwemafuta.
Zvakanakira: Macompressor emupombi eDCM anodzivirira ngura uye akasimba zvikuru akagadzirwa nemakambani akaita seChongtong Group anogona kushandisazve simba remupombi wechipiri, zvichideredza kushandiswa kwesimba rekushanda kwakazara neanopfuura 40%, zvichiita kuti DCM idzoke zvakanaka uye isingadhuri.
2.Tekinoroji yeKuora Kwemhepo Inoshanda Zvishoma
Kugadzira zvinhu zvitsva zvinokonzeresa kuti DCM iparadze zvinobudirira uye zvachose kuita zvinhu zvisina njodzi pakupisa kwakaderera (70-120°C).
III. Mashandisirwo Akakosha Mukugadzira Zvinhu Zvepamusoro-soro Nezvinhu Zvitsva
Mune dzimwe nzvimbo dzemazuva ano uko zvinodiwa pakushanda kwezvinhu zvakanyanya, hunhu hweDCM hwakasiyana hunoita kuti isatsiviwe kwenguva pfupi.
1.Kugadziriswa Kwezvinhu Zvemagetsi
Mashandisirwo: Mukugadzirira ma perovskite solar cells, OLED light-emitting layers, uye high-end photoresists, ma uniform thin films anodiwa. Nekuda kwekunyungudika kwayo kwakanaka uye kufashaira kuri pakati nepakati kwema polymers akawanda ane simba guru uye mamorekuru madiki, DCM inoramba iri imwe ye solvents dzinofarirwa murabhoritari uye kugadzirira mafirimu emhando yepamusoro nemadiki.
2.Kubvisa Mvura Inonyanya Kukosha
Mashandisirwo: DCM inogona kushandiswa semuchina wekugadzirisa kana wekugadzirisa pamwe chete neCO₂ inokosheswa zvakanyanya pakuburitsa zvinhu zvakasiyana-siyana (semuenzaniso, maalkaloid, mafuta anokosha) kubva muzvigadzirwa zvechisikigo. Kushanda kwayo mukubvisa uye kusarudza kwakanakisa kupfuura kwemvura yakachena inokosheswa zvikuru yeCO₂.
IV. Pfupiso uye Maonero
Pakazara, mashandisirwo matsva e dichloromethane ari kufamba munzira mbiri dzakajeka:
Kugadzira Maitiro: Kuchinja kubva pakushandiswa kwe "open consumption" kuenda ku "closed-loop circulation," kuchishandisa senzira inoshanda yekushanda pamwe chete netekinoroji yepamusoro yekudzokorodza, nechinangwa chekupedzisira chekuderedza kushandiswa kwemagetsi uye kusvibiswa kwemhepo munzvimbo.
Kuvandudza Kukosha: Kuchengetedza chinzvimbo chayo muminda chaiyo yetekinoroji yepamusoro uko kwakaoma kutsiva (semuenzaniso, mishonga yepamusoro, zvinhu zvemagetsi) nekubatanidza nedzimwe tekinoroji yepamusoro kuti ishandise kukosha kwayo kwakasiyana.
Zviitiko zveramangwana zvicharamba zvichitenderera pamusoro penyaya yekuti "zvakachengeteka, zvine nharaunda, uye zvinoshanda zvakanyanya." Kune rumwe rutivi, kutsvagurudza pamusoro pezvinyungudutsa zvisina chepfu zvakanyanya kuchafambira mberi, ukuwo kune rumwe rutivi, matekinoroji ekugadzirisa mashandisirwo nekurasa DCM acharamba achichinja, zvichideredza njodzi mumamiriro ezvinhu apo kushandiswa kwayo kusingadzivisiki.
