Dichloromethane: Ntchito Zatsopano Ziyenera Kuyang'ana pa Kugwiritsa Ntchito Motetezeka komanso Mogwira Mtima

Kugwiritsa ntchito kwatsopano kwa dichloromethane (DCM) pakadali pano sikukukhudza kukulitsa ntchito yake yachikhalidwe monga chosungunulira koma m'malo mwake "momwe mungagwiritsire ntchito ndikuchisamalira mosamala komanso moyenera" ndikufufuza kufunika kwake kwapadera m'magawo enaake apamwamba.

I. Kupanga Zinthu Mwatsopano: Monga "Chida Chogwiritsira Ntchito Njira" Chobiriwira komanso Chogwira Ntchito

Chifukwa cha kusasinthasintha kwake kwabwino, kutentha pang'ono, komanso kulimba kwake, DCM imagwiritsidwa ntchito ngati "chithandizo chothandiza" muukadaulo watsopano m'malo mokhala gawo la chinthu chomaliza, potero kuchepetsa kugwiritsidwa ntchito konse ndi mpweya woipa.

1.Wothandizira Wogwira Ntchito Wowononga Zinthu wa Polyolefin

Zatsopano: Makampani ena apanga ukadaulo womwe umayambitsa DCM ngati chothandizira kuchotsa zinthu mu njira yochotsera ma screw a polyolefins (monga POE).

Ubwino: DCM imachepetsa kukhuthala kwa zinthu ndi kupanikizika pang'ono pamwamba, zomwe zimapangitsa kuti ntchito yochotsa ma monomers otsala ndi zinthu zachilengedwe zosakhazikika ikhale yotsika. Njirayi ili ndi zofunikira zochepa pazida komanso mtengo wake ndi wotsika, zomwe zimapangitsa kuti ikhale yogwiritsa ntchito mphamvu zambiri komanso yothandiza poyerekeza ndi njira yachikhalidwe yochotsera mpweya wambiri kapena kutentha kwambiri.

2.Green Reaction Medium ya Kupanga Mankhwala

Zatsopano: Mu makampani opanga mankhwala, DCM ikadali yovuta kuisintha kwathunthu chifukwa cha mphamvu zake zotha kusungunuka. Zatsopanozi zili m'kuphatikiza ndi ukadaulo wapamwamba wa reaction ndi njira zobwezeretsanso zinthu kuti zitheke kuzungulira kwa closed-loop.

Kugwiritsa Ntchito: Yophatikizidwa ndi mankhwala opitilira kuyenda ndi ma reactor opangidwa okha, DCM solvent imabwezeretsedwanso nthawi yeniyeni ndikuyeretsedwa kudzera mumakina obwezeretsa condensation omwe ali mkati mwa intaneti, zomwe zimachepetsa kwambiri kugwiritsa ntchito kamodzi kokha komanso zoopsa zowonekera.

II. Ukadaulo Wozungulira: Kubwezeretsanso ndi Kuwononga Bwino

Poyankha malamulo okhwima okhudza chilengedwe, pakhala zinthu zatsopano zambiri zomwe zapangidwa muukadaulo wobwezeretsanso zinthu wa DCM komanso njira zochizira zinthu zomwe zimagwiritsidwa ntchito kumapeto kwa chitoliro.

1.Ukadaulo Wogwiritsa Ntchito Mpweya Wowonjezera Mphamvu (MVR) wa Makina Ogwiritsa Ntchito Mphamvu

Zatsopano: Ukadaulo wa Mechanical Npor Recompression (MVR) umagwiritsidwa ntchito pobwezeretsa mpweya woipa wa DCM womwe uli ndi mphamvu zambiri.

Ubwino: Ma compressor a nthunzi a DCM osagonjetsedwa ndi dzimbiri komanso okhazikika kwambiri omwe amapangidwa ndi makampani monga Chongtong Group amatha kugwiritsanso ntchito mphamvu ya nthunzi yachiwiri, kuchepetsa kugwiritsa ntchito mphamvu yonse ndi 40%, zomwe zimathandiza kuti DCM ibwezeretsedwe bwino komanso mopanda ndalama.

2.Ukadaulo Wochepetsa Kuwonongeka kwa Zinthu Zotentha Kwambiri Wogwiritsa Ntchito Mphamvu Yapamwamba

Zatsopano: Kupanga ma catalyst atsopano kuti awononge bwino komanso kwathunthu DCM kukhala zinthu zopanda vuto pa kutentha kochepa (70-120°C).

III. Kugwiritsa Ntchito Kwapadera Pakupanga Zinthu Zapamwamba ndi Zipangizo Zatsopano

M'magawo ena apamwamba pomwe zofunikira pakugwira ntchito kwa zinthu zimakhala zapamwamba kwambiri, mawonekedwe apadera a DCM amawapangitsa kuti asasinthidwe kwakanthawi.

1.Kukonza Zinthu Zogwiritsa Ntchito Photoelectric

Kugwiritsa Ntchito: Pokonzekera maselo a dzuwa a perovskite, zigawo zotulutsa kuwala za OLED, ndi ma photoresist apamwamba kwambiri, mafilimu opyapyala ofanana kwambiri amafunika. Chifukwa cha kusungunuka kwake bwino komanso kutentha pang'ono kwa ma polima ambiri ogwira ntchito bwino komanso mamolekyu ang'onoang'ono, DCM ikadali imodzi mwa zosungunulira zomwe zimakondedwa kwambiri pokonzekera bwino kwambiri mafilimu apamwamba komanso ang'onoang'ono.

2.Kutulutsa Madzi Oopsa Kwambiri

Kugwiritsa Ntchito: DCM ingagwiritsidwe ntchito ngati chosinthira kapena chosungunulira pamodzi ndi CO₂ yofunikira kwambiri kuti ichotse bwino komanso mosankha bwino mankhwala enaake (monga ma alkaloid, mafuta ofunikira) kuchokera ku zinthu zachilengedwe. Kugwira ntchito kwake bwino komanso kusankha bwino kwa madzi a CO₂ ofunikira kwambiri n'kwabwino kuposa madzi a CO₂ ofunikira kwambiri.

IV. Chidule ndi Kawonedwe

Ponseponse, kugwiritsa ntchito kwatsopano kwa dichloromethane kukuyenda m'njira ziwiri zomveka bwino:

Kusintha kwa Njira: Kusintha kuchoka pa "kugwiritsa ntchito momasuka" kupita ku "kuzungulira kotsekedwa," pogwiritsa ntchito njira yothandiza yogwirira ntchito limodzi ndi ukadaulo wapamwamba wobwezeretsanso zinthu, ndi cholinga chachikulu chochepetsa kugwiritsa ntchito ukonde ndi kutulutsa mpweya woipa m'chilengedwe.

Kusintha kwa Mtengo: Kusunga malo ake m'magawo enaake aukadaulo wapamwamba komwe kumakhala kovuta kusintha (monga mankhwala apamwamba, zipangizo zamagetsi) pophatikiza ndi ukadaulo wina wapamwamba kuti ugwiritse ntchito phindu lake lapadera.

Zochitika zamtsogolo zipitiliza kuzungulira mutu wakuti "zotetezeka, zobiriwira, komanso zogwira mtima kwambiri." Kumbali imodzi, kafukufuku wa zosungunulira zina zopanda poizoni wambiri zidzapita patsogolo, pomwe kumbali ina, ukadaulo wowongolera kugwiritsa ntchito ndi kutaya DCM udzapitirirabe kusintha, kuchepetsa zoopsa pazochitika zomwe kugwiritsa ntchito kwake sikungapeweke.
