I-Dichloromethane iyisithako esisetshenziswa kabanzi embonini yokukhiqiza, yokucubungula, kanye neyokuhlanza nsuku zonke. Inokuncibilika okunamandla, ukuguquguquka okusheshayo, kanye nobuthi obuncane, isetshenziswa kakhulu ekuhlanzeni, ekukhipheni, ekucubunguleni i-coating, nakwezinye izimo. Kodwa-ke, abasebenzisi abaningi abavamile kanye nezisebenzi ezisebenza phambili banokuqonda okulinganiselwe ngayo, bavame ukudideka ngezingozi zayo zokuphepha, ukwenqatshelwa kokusetshenziswa, kanye neziqondiso zokuvikela. Lesi sihloko siphendula imibuzo evame ukubuzwa mayelana ne-dichloromethane ngefomethi ye-Q&A, sisiza umphakathi ukuqonda nokusebenzisa le khemikhali eluhlaza ngokwesayensi nangokuhambisana nayo.
1. Iyini i-dichloromethane, futhi yiziphi izici zayo eziyisisekelo?
I-Dichloromethane (DCM), enefomula yamakhemikhali i-CH₂Cl₂, iwuketshezi oluphilayo olungenambala, olusobala, noluguquguqukayo kakhulu olunephunga elimnandi elincane. Njengenhlanganisela ye-hydrocarbon ene-halogen, ikhombisa ukuncibilika okuhle kakhulu futhi ingancibilikisa kahle amafutha, i-resin, kanye nerabha, kanye nokukhipha izinto ezahlukahlukene eziphilayo. Uma kuqhathaniswa nezinyibilikisi ezisekelwe ku-trichlorethylene kanye ne-benzene, i-dichloromethane iyi-ayishisi futhi inezingozi zokuqhuma eziphansi kakhulu, okwenza kube yindawo eyinhloko yokufaka esikhundleni sezinyibilikisi zezimboni ezivuthayo. Ukuguquguquka kwayo okunamandla kwenza kube nokuhwamuka okusheshayo ekushiseni kwegumbi, okusho ukuthi ukuvezwa ekuphefumuleni kuyingozi enkulu yokuphepha kwayo.
2. Yiziphi izindlela eziyinhloko zokusebenzisa i-dichloromethane empilweni yansuku zonke nasembonini?
I-Dichloromethane ihlanganisa izinhlobo eziningi zezimo zezimboni kanye nezomphakathi. Kwezimboni, isebenza njenge-ejenti yokususa amafutha kanye nesihlanzi esinembile sehadiwe, izingxenye ze-elekthronikhi, kanye nezikhunta. Iphinde yamukelwe njengesinyibilikisi sokukhipha ekucubungulweni kwemithi nokudla ukuze ihlukanise izithako ezisebenzayo ezintweni zokusetshenziswa. Empilweni yansuku zonke, iningi lama-remover opende, ama-adhesive cleaner, kanye ne-leather detergents aqukethe i-dichloromethane njengesithako esiyinhloko. Ngaphezu kwalokho, isetshenziswa ekukhiqizeni ama-refrigerant kanye nama-foam agents, esebenza njengesinyibilikisi esiyisisekelo esibalulekile embonini elula..
3. Ingabe i-dichloromethane inobuthi, futhi yiziphi izingozi zempilo ezibangelwa yiyo?
Umbono ovamile oyiphutha ukuthi i-dichloromethane iphephile ngokuphelele ngenxa yokuthi inobuthi obuphansi. Eqinisweni, nakuba ihlukaniswa njengekhemikhali enobuthi obuphansi,Ukuchayeka isikhathi eside kanye nokuphefumula okugxile kakhulu kungabangela umonakalo omkhulu ngokomzimbaUkuchayeka isikhathi esifushane ekugxilweni okuphezulu kucasula ulwelwesi lwamafinyila lwamehlo, impumulo nomphimbo, okuholela esiyezini, ekhanda elibuhlungu, isicanucanu, ukuqina kwesifuba, kanye nokukhathala. Ezimweni ezimbi kakhulu, kucindezela uhlelo lwezinzwa oluphakathi, okuholela ekozeleni nasekudidekeni.
Ukuchayeka isikhathi eside ezingeni eliphansi kubangela ukulimala okucashile nokuqhubekayo. Kuhlala kuphazamisa ukusebenza kwesibindi nezinso futhi kuphazamise ukusebenza kwe-metabolism yomuntu. Ukucasuka okungapheli kokuphefumula kungadala i-pharyngitis kanye ne-bronchitis. Okuphawulekayo ukuthi i-dichloromethane ephefumulayo iguqulwa ibe yizinto ezinobuthi emzimbeni womuntu. Ubuthi obuqongelelekile bungalimaza izinhlelo ze-hematopoietic nezezinzwa, okubangela ukuncipha kwenkumbulo kanye nokungabi namandla ezithweni. Njengamanje, i-dichloromethane ibhalwe njengesifo esibangela umdlavuza kubantu, esidinga ukulawulwa okuqinile kwesikhathi sokuvezwa kanye nokuhlushwa.
4. Yimiphi imisebenzi yansuku zonke ebeka izingozi ezinkulu?
Izingozi eziningi zokuphepha zivela emisebenzini engeyona ejwayelekile. Okokuqala, ukusebenzisa izihlanzi eziqukethe i-DCM noma izisusa upende ezindaweni ezivalekile, ezingenawo umoya kubangela ukunqwabelana komhwamuko futhi kuholele kalula ebuthi. Okwesibili, ukuthintana ngqo ngesandla kulimaza ungqimba oluvikela isikhumba, okubangela ukoma, ukubomvu, kanye nokusabela kokungezwani komzimba, kuyilapho ubuthi bungangena esikhumbeni bungene egazini. Ngaphezu kwalokho, ukuxuba i-dichloromethane nama-acid aqinile noma ama-alkali aqinile kubangela ukusabela kwamakhemikhali futhi kukhiqize amagesi anobuthi abhubhisayo, okuholela ezingozini ezimbili zokuphepha.
5. Yiziphi izindlela zokwelapha eziphuthumayo ngemva kokuchayeka ku-dichloromethane?
Uma kwenzeka uphefumula umusi ogcwele amanzi amaningi, hamba ngokushesha uye endaweni enomoya omuhle, ukhulule izingubo, futhi uqhubeke nokuphefumula ngaphandle kokuphazamiseka. Funa ukwelashwa kwezokwelapha ngokushesha uma kuvela isiyezi noma ubunzima bokuphefumula. Ukuze uthole ukuthintana kwesikhumba, hlanza indawo ethintekile kahle ngamanzi agobhozayo bese ushintsha izingubo ezingcolile ukuze ugweme ukugqwala okuqhubekayo. Uma uketshezi lungena emehlweni, hlanza njalo ngamanzi ahlanzekile imizuzu engaphezu kwengu-15 ngaphandle kokuhlikihla amehlo, bese uthola ukuhlolwa kochwepheshe bezokwelapha ngesikhathi esifanele.
6. Ungabavikela kanjani abasebenzi abavezwe isikhathi eside?
Ukuvikelwa okuphumelelayo kuncike ekungeneni komoya okwanele, izinyathelo zokuhlukanisa, kanye nokusebenza okujwayelekile. Izindawo zokusebenza zezimboni kumele zihlonyiswe ngezinhlelo zokungenisa umoya ophumayo ukuze kuncishiswe amazinga e-solvent emoyeni. Abasebenzi kumele bagqoke imaski yegesi, amagilavu amelana ne-solvent, kanye nezibuko zokuzivikela ukuze bagweme ukuvezwa ngqo esikhumbeni nasekuphefumuleni. Kubasebenzisi abavamile, gcina amafasitela evulekile njalo ngesikhathi sokusetshenziswa futhi ugweme ukusebenza isikhathi eside ezindaweni ezivalekile zangaphakathi. Abasebenzi abavezwe isikhathi eside kufanele bahlanganyele ekuhlolweni kwempilo yomsebenzi njalo ukuze kuvinjelwe ukulimala okungenzeka kwesibindi, izinso kanye nohlelo lwezinzwa.
7. Ingabe i-dichloromethane ibangela ukungcoliswa kwemvelo? Ungalahla kanjani uketshezi olungcolile ngendlela efanele?
I-dichloromethane eguquguqukayo iba ama-organic compounds aguquguqukayo (ama-VOC) futhi ingcolisa umoya. Ukukhishwa okungalungile koketshezi olungcolile kungena enhlabathini nasemanzini angaphansi komhlaba. Ngenxa yokubola kwemvelo okungekuhle, kubangela ukungcoliswa kwamanzi nenhlabathi isikhathi eside. I-dichloromethane yemfucuza yezimboni kumele iqoqwe futhi ivalwe ngokulinganayo, futhi ilahlwe yizikhungo zobungcweti eziqeqeshiwe. Ukukhishwa nokulahlwa okungahleliwe akuvunyelwe ngokuphelele ukuvimbela umonakalo wemvelo.
Ekuphetheni, i-dichloromethane iyisithako sezimboni esibaluleke kakhulu esingenazo izingozi zokusha noma ukuqhuma, kodwa ibeka ubuthi obuqondile kanye nezingozi zempilo. Kubasebenzi bezimboni kanye nabasebenzisi abavamile, ukuqaphela izakhiwo zayo, ukugwema imisebenzi eyingozi, kanye nokusebenzisa izinyathelo zesayensi zokuvikela kungakhulisa inani layo lokusetshenziswa ngenkathi kuvikelwa ngempumelelo impilo yomuntu siqu kanye nokuphepha kwemvelo.
