Dichloromethane chinhu chinoshandiswa zvakanyanya mumaindasitiri ekugadzira, kugadzirisa, uye kuchenesa zuva nezuva. Ichishandiswa zvakanyanya mukunyunguduka, kushanduka-shanduka nekukurumidza, uye chepfu shoma, inoshandiswa zvakanyanya mukuchenesa, kubvisa, kugadzirisa machira, uye zvimwe zviitiko. Zvisinei, vazhinji vashandisi venguva dzose nevashandi vepamberi vane ruzivo rushoma nezvayo, vanowanzovhiringidzika nezvenjodzi dzayo dzekuchengetedza, zvirambidzo zvekushandisa, uye nhungamiro dzekudzivirira. Chinyorwa chino chinopindura mibvunzo inowanzo bvunzwa nezve dichloromethane muchimiro cheQ&A, zvichibatsira veruzhinji kunzwisisa nekushandisa iyi kemikari nenzira yesainzi uye zvinoenderana nezvinodiwa.
1. Chii chinonzi dichloromethane, uye ndeapi maitiro ayo makuru?
Dichloromethane (DCM), ine fomura yemakemikari CH₂Cl₂, imvura isina ruvara, inoonekera, uye inoshanduka-shanduka zvikuru ine hwema hunotapira hushoma. Semusanganiswa wehydrocarbon une halogenated, inoratidza kunyunguduka kwakanaka uye inogona kunyungudutsa mafuta, resin, uye rabha zvinobudirira, pamwe nekubvisa zvinhu zvakasiyana-siyana zve organic. Kana ichienzaniswa ne trichloroethylene uye benzene-based solvents, dichloromethane iriisingatsvi ine njodzi shoma dzekuputika, zvichiita kuti ive chinhu chikuru chinotsiva zvinonyungudutsa zvemaindasitiri zvinobvira moto. Kusagadzikana kwayo kwakasimba kunoita kuti ipfuure nekukurumidza patembiricha yemumba, zvinoreva kuti kufemerwa nayo ndiyo njodzi huru yekuchengetedza.
2. Ndeapi mashandisirwo makuru e dichloromethane muhupenyu hwezuva nezuva uye mumaindasitiri?
Dichloromethane inofukidza zvakasiyana-siyana zvemaindasitiri nedzevanhuwo zvavo. Mumaindasitiri, inoshanda semushonga wekubvisa mafuta uye kuchenesa nemazvo kwemidziyo, zvikamu zvemagetsi, uye mapundu. Inoshandiswawo semushonga wekubvisa mafuta mumishonga nekugadzira chikafu kuti iparadzanise zvinhu zvinoshanda kubva muzvinhu zvakabikwa. Muhupenyu hwezuva nezuva, zvinhu zvakawanda zvinobvisa pendi, zvinonamira, uye sipo dzedehwe zvine dichloromethane sechinhu chikuru. Pamusoro pezvo, inoshandiswa mukugadzira mafiriji uye zvinhu zvinofema furo, ichishanda semushonga wekutanga unokosha muindasitiri yechiedza..
3. Dichloromethane ine chepfu here, uye inokonzera njodzi dzipi pahutano?
Pfungwa isiriyo ndeyekuti dichloromethane yakachengeteka zvachose nekuda kwechepfu shoma. Kutaura zvazviri, kunyangwe ichiiswa muchikamu chekemikari ine chepfu shoma,kugara kwenguva refu uye kufema zvakanyanya kunogona kukonzera kukuvara kwakanyanya mumuviriKugara kwenguva pfupi uchinwa doro rakawanda kunotsamwisa maziso, mhino, nehuro, zvichikonzera dzungu, musoro, kuda kurutsa, kusimba kwechipfuva, uye kuneta. Muzviitiko zvakakomba, zvinoderedza tsinga dzemuviri, zvichikonzera hope nekuvhiringidzika.
Kugara uchibatwa zvisina kunaka kwenguva refu kunokonzera kukuvara kwakavanzika uye kunogara kwenguva refu. Kunoramba kuchikanganisa mashandiro echiropa neitsvo uye kukanganisa mashandiro emuviri wemunhu. Kutsamwiswa kufema kwenguva refu kunogona kukonzera pharyngitis nebronchitis. Zvinonyanya kukosha, dichloromethane inofemwa inogadzirwa kuita zvinhu zvine chepfu mumuviri wemunhu. Chepfu dzakaunganidzwa dzinogona kukuvadza masisitimu eropa netsinga, zvichikonzera kudzikira kwendangariro nekushaya simba mumakumbo. Parizvino, dichloromethane inonyorwa semushonga unofungidzirwa kuti unokonzera kenza mumuviri wemunhu, inoda kudzora kwenguva uye huwandu hwemuviri.
4. Ndeapi mabasa ezuva nezuva ane njodzi huru?
Njodzi zhinji dzekuchengetedza dzinobva mukushanda kusiri kwetsika. Chekutanga, kushandisa michina yekuchenesa ine DCM kana zvinobvisa pendi munzvimbo dzakavharirwa, dzisina mhepo kunokonzera kuunganidzwa kwemhepo uye zviri nyore kukonzera chepfu. Chechipiri, kubata ganda nemaoko zvakananga kunokuvadza ganda rinodzivirira, zvichikonzera kuoma, kutsvuka, uye allergic reactions, nepo chepfu ichigona kupinda muganda yopinda muropa. Uyezve, kusanganisa dichloromethane neacids yakasimba kana alkalis yakasimba kunokonzera makemikari reactions uye kunogadzira magasi ane chepfu anoparadza, zvichikonzera njodzi mbiri dzekuchengetedza.
5. Ndeapi marapirwo ekukurumidza mushure mekusangana ne dichloromethane?
Kana munhu akafema utsi hwakanyanya, enda kunzvimbo ine mhepo inofema zvakanaka, sunungura mbatya, uye ramba uchifema pasina chinomukanganisa. Tsvaga rubatsiro rwechiremba nekukurumidza kana paine dzungu kana matambudziko ekufema. Kana ganda rako rikagunzva, sukurudza nzvimbo yacho nemvura inoyerera zvakanaka uye dzorera mbatya dzine tsvina kuti usaramba uchingoora. Kana mvura yacho ikapararira mumaziso, sukurudza mvura yakachena nguva dzose kwemaminitsi anopfuura gumi nemashanu usingakwize maziso, uye ongororwa nachiremba nenguva.
6. Nzira yekudzivirira vashandi vanenge vakavharirwa kwenguva refu sei zuva nezuva?
Dziviriro inoshanda inobva pakufefetera kwakakwana, matanho ekuzviparadzanisa, uye mashandiro akajairwa. Nzvimbo dzebasa dzemaindasitiri dzinofanira kunge dzakashongedzerwa masisitimu ekufema eutsi kuti dzideredze huwandu hwezvinhu zvinonyungudutsa mumhepo. Vashandi vanofanira kupfeka mamasiki egasi, magirovhosi anodzivirira zvinonyungudutsa, uye magirazi ekudzivirira kudzivirira kusangana neganda zvakananga uye kufema. Kune vashandisiwo zvavo, garai makavhura mahwindo panguva yekushandisa uye dzivisai kushanda kwenguva refu munzvimbo dzakavharirwa mukati. Vashandi vanoonekwa kwenguva refu vanofanirwa kutora chikamu mukuongororwa kwehutano hwebasa nguva dzose kudzivirira kukuvara kunogona kuitika kuchiropa, itsvo, uye tsinga.
7. Ko dichloromethane inokonzera kusvibiswa kwezvakatipoteredza here? Nzira yekurasa marara nenzira inoenderana nemutemo here?
Dichloromethane yakaora inova makemikari anoshanduka kuita organic (VOCs) uye inosvibisa mhepo. Kurasa tsvina zvisina kunaka kunopinda muvhu nemumvura yepasi pevhu. Nekuda kwekuora kwechisikigo, kunokonzera kusvibiswa kwemvura nevhu kwenguva refu. Dichloromethane yemarara emaindasitiri inofanira kuunganidzwa uye kuvharwa zvakaenzana, uye kuraswa nemasangano ane hunyanzvi. Kurasa tsvina nekurasa marara zvisina kurongeka kunorambidzwa zvakasimba kudzivirira kukuvara kwezvakatipoteredza.
Mukupedzisa, dichloromethane chinhu chinonyungudutsa chemumaindasitiri chinokosha zvikuru chisina njodzi yekupisa kana kuputika, asi chine chepfu chaiyo uye njodzi kuhutano. Kune vashandi vemumaindasitiri nevashandisiwo zvavo, kuziva hunhu hwayo, kudzivirira mashandiro ane njodzi, uye kushandisa matanho ekudzivirira esainzi kunogona kuwedzera kukosha kwayo ukuwo ichichengetedza hutano hwevanhu nekuchengetedzwa kwezvakatipoteredza.
