Dichloromethane: Uburyo bushya bwo gukoresha bugomba kwibanda ku ikoreshwa ryizewe kandi rinoze

Imikoreshereze mishya ya dichloromethane (DCM) ubu ntabwo ishingiye ku kwagura uruhare rwayo gakondo nk'umusemburo ahubwo ishingiye ku "uburyo bwo kuyikoresha no kuyifata neza mu mutekano no mu buryo bunoze" no gushakisha agaciro kayo kadasanzwe mu nzego runaka z'ikoranabuhanga rigezweho.

I. Guhanga udushya mu mikorere: Nk' "Igikoresho cy'imikoreshereze" gishimishije kandi gishimishije

Bitewe n’ihindagurika ryayo ryiza, aho ishyuha cyane, ndetse n’ubushobozi bwayo bwo kuyungurura, DCM ikoreshwa nk'"ubufasha mu mikorere" mu ikoranabuhanga rigezweho aho gukoreshwa nk'igice cy'umusaruro wa nyuma, bityo ikagabanya ikoreshwa n'ibyuka bihumanya muri rusange.

1.Umukozi Ukora neza wo Guhindura Ingufu mu Gukora Polyolefin

Udushya: Hari ibigo byateje imbere ikoranabuhanga rishyiraho DCM nk'ikintu gifasha mu gukuraho screw muri polyolefins (urugero, POE).

Akamaro: DCM igabanya neza ubukana bw'ibikoresho n'umuvuduko w'igice cy'ubuso, yongera cyane imikorere yo gukuraho monomer zisigaye n'ibinyabutabire bihindagurika. Ubu buryo bufite ibikoresho bike kandi buhendutse cyane, bigatuma bukoresha ingufu nke kandi bunoze ugereranije n'uburyo busanzwe bwo gusenya ibintu hakoreshejwe imvange nyinshi cyangwa ubushyuhe bwinshi.

2.Uburyo bwo gukora imiti mu buryo bw'icyatsi kibisi

Udushya: Mu nganda zikora imiti, DCM iracyagoranye kuyisimbura burundu bitewe n’ubushobozi bwayo bukomeye bwo kuyitunganya. Udushya turi mu kuyihuza n’ikoranabuhanga rigezweho ryo gukora isuzuma n’uburyo bwo kongera gukoresha imiti kugira ngo habeho uruziga rw’imiti rudacika.

Ikoreshwa: Ihujwe na shimi ikomeza kugenda neza hamwe na reactors za synthesis zikora, DCM solvent ivugururwa mu buryo bwihuse kandi igasukurwa binyuze muri sisitemu zo kugarura amazi mu buryo bwubatswe kuri interineti, bigabanya cyane ikoreshwa rimwe gusa n'ibyago byo guhura n'ibintu.

II. Ikoranabuhanga rizunguruka: Gukoresha neza no kwangiza ibintu

Mu rwego rwo gusubiza ku mabwiriza akaze agenga ibidukikije, hakozwe udushya twinshi mu bijyanye no kongera gukoresha DCM mu gutunganya no gutunganya imiyoboro.

1.Ikoranabuhanga ryo Gusubiza Ubushyuhe mu Buryo Bukoresha Ingufu (MVR)

Udushya: Ikoranabuhanga rya Mechanical Vapor Recompression (MVR) rikoreshwa mu kugarura umwuka wa DCM urimo ubushyuhe bwinshi.

Akamaro: Compressor z’umwuka za DCM zirwanya ingese kandi zihamye cyane zakozwe n’ibigo nka Chongtong Group zishobora kongera gukoresha ingufu z’umwuka w’inyongera, bikagabanya ingufu zikoreshwa cyane ku kigero kirenga 40%, bigatuma DCM isubiranamo neza kandi ku giciro gito.

2.Ikoranabuhanga ryo kwangiza ikirere mu bushyuhe buke kandi rikora neza cyane

Udushya: Guteza imbere uburyo bushya bwo kwangiza DCM mu buryo bwiza kandi busesuye mu bushyuhe buri hasi (70-120°C).

III. Ikoreshwa ryihariye mu nganda zigezweho n'ibikoresho bishya

Mu nzego zimwe na zimwe zigezweho aho ibisabwa mu mikorere y'ibikoresho biri hejuru cyane, imiterere yihariye ya DCM ituma idasimburwa by'agateganyo.

1.Gutunganya ibikoresho by'amashanyarazi

Ikoreshwa: Mu gutegura uturemangingo tw’izuba twa perovskite, urwego rutanga urumuri rwa OLED, hamwe n’udusimba two mu rwego rwo hejuru, hakenewe uturemangingo tworoheje cyane dufite isuku nyinshi. Bitewe n’uko ishonga neza kandi ishyuha buhoro buhoro kuri polymer nyinshi zikora neza na molekile nto, DCM iracyari imwe mu misemburo ikunzwe cyane mu gutegura neza muri laboratwari no mu buryo buciriritse uturemangingo tw’isuku.

2.Gukuramo amazi ashyushye cyane

Imikoreshereze: DCM ishobora gukoreshwa nk'umusemburo cyangwa ivangavanze na CO₂ ikoreshwa cyane mu gukuramo ibintu runaka neza kandi bitoranyije neza (urugero: alkaloids, amavuta y'ingenzi) mu bicuruzwa karemano. Ingufu zayo zo gukuramo no guhitamo neza biruta iby'amazi ya CO₂ akoreshwa cyane.

IV. Incamake n'Icyerekezo

Muri rusange, uburyo bushya bwo gukoresha dichloromethane buri kugenda mu byerekezo bibiri bisobanutse neza:

Udushya mu mikorere: Guhindura kuva ku "gukoresha ibintu bifunguye" ukajya ku "gukoresha ibintu bifunze," bigakoreshwa nk'uburyo bwiza bwo gukora ibintu hamwe n'ikoranabuhanga rigezweho ryo kongera gukoresha ibintu, hagamijwe kugabanya ikoreshwa ry'ibintu n'ibyuka bihumanya ikirere.

Agaciro gashya: Gukomeza umwanya wayo mu nzego zihariye z’ikoranabuhanga rihanitse aho bigoye kuyisimbura (urugero, imiti igezweho, ibikoresho by’amashanyarazi) binyuze mu guhuza n’izindi koranabuhanga zigezweho kugira ngo ikoreshe agaciro kayo kadasanzwe.

Iterambere ry'ejo hazaza rizakomeza kugaruka ku nsanganyamatsiko igira iti “mutekano, mu kubungabunga ibidukikije, kandi mu buryo bunoze kurushaho.” Ku ruhande rumwe, ubushakashatsi ku binyabutabire bidafite uburozi buzatera imbere, mu gihe ku rundi ruhande, ikoranabuhanga ryo kunoza ikoreshwa n'itabwa rya DCM rizakomeza gutera imbere, bigabanye ibyago mu bihe aho ikoreshwa ryayo ridashobora kwirindwa.
