I-Diethylene Glycol (DEG)iyikhemikhali evamile yezinto eziphilayo esetshenziswa kabanzi ezisetshenziswa ezimbonini ngenxa yokukwazi kwayo ukuxazulula izinto kahle kanye nokuguquguquka okuphansi. Kodwa-ke, njengekhemikhali eyingozi, i-DEG iphinde iveze izingozi ezithile zempilo kanye nezemvelo. Lesi sihloko siphendula eminye yemibuzo evame ukubuzwa mayelana ne-diethylene glycol ukusiza amabhizinisi nabantu ngabanye ukuthi bayiqonde futhi bayisebenzise ngokuphephile.
1. Kuyini i-Diethylene Glycol?
I-Diethylene glycol (DEG) iwuketshezi olungenambala, olungenaphunga, oluqinile olunefomula yamakhemikhaliC₄H₁₀O₃Inezakhiwo ze-hygroscopic kanye namakhono amahle kakhulu okunyibilikisa. Njenge-ethylene glycol, i-DEG ingeyomndeni we-glycol, kodwa ngokuvamile ibhekwa njengenobuthi kakhulu futhi ingaba yingozi enkulu empilweni ngokuyidla, ukuyiphefumula, noma ukuyimunca isikhumba.
2. Yiziphi Izindlela Ezivamile Zokusebenzisa I-Diethylene Glycol?
Ngenxa yokuqina kwayo, izakhiwo zayo zokuxazulula izinkinga, kanye nezici zokugcina umswakama, i-DEG isetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni:
Izicelo Ze-solvent
I-Diethylene glycol ivame ukusetshenziswa njengesithako ekukhiqizeni upende, izembozo, ama-resin, uyinki, kanye nezinamathiseli. Isiza ekulawuleni ukujiya nokuthuthukisa ukusebenza komkhiqizo.
I-Antifreeze kanye ne-Coolerant
Ngenxa yokuthi ishisa kakhulu futhi ibanda kancane, i-DEG isetshenziswa kwezinye izindlela zokuvimbela ukuqandisa kanye nezinhlelo zokupholisa zezimboni.
I-Chemical Intermediate
I-DEG isebenza njengezinto ezibalulekile zokusetshenziswa ekukhiqizeni ama-plasticizer, ama-resin e-polyester, namanye amakhemikhali akhethekile.
I-Humectant kanye ne-Dehydrating Agent
Kwezinye izindlela zokucubungula igesi yezimboni, ukukhiqizwa kwezindwangu, kanye nokukhiqizwa kwezinto zikagesi, i-DEG isetshenziswa njenge-ejenti emunca umswakama futhi elawula umswakama.
Nakuba inezinhlelo zokusebenza eziningi zezimboni, i-diethylene glycol kufaneleungalokothi usetshenziswe njengesithako sokudla noma semithingenxa yobuthi bayo.
3. Ziyini Izingozi Ze-Diethylene Glycol?
I-Diethylene glycol ingaba yingozi enkulu empilweni nakwezemvelo uma ingaphathwa kahle.
Izingozi Zempilo
Ukungenisa
Ukugwinya ngengozi kungaholela ekucasukeni, ekuhlanzeni, ebuhlungwini besisu, ekulimaleni kwezinso, emiphumeleni yezinzwa, futhi ezimweni ezimbi kakhulu, ukufa.
Ukuthintana Kwesikhumba
Ukuchayeka esikhumbeni ngqo kungabangela ukucasuka. Ukuthintana isikhathi eside noma okuphindaphindiwe kungavumela ukumuncwa esikhumbeni, okungase kuholele ebuthi emzimbeni.
Ukuphefumula
Ukuphefumula umusi we-DEG noma inkungu kungacasula umgudu wokuphefumula futhi kubangele izimpawu ezifana nobuhlungu bekhanda, isiyezi, kanye nokungakhululeki kokuphefumula.
Izingozi Zemvelo
• I-DEG ingaba yingozi ezintweni eziphilayo zasemanzini uma idedelwa emanzini.
• Kungase kuhlale isikhathi eside enhlabathini futhi kube nomthelela ekungcolisweni kwemvelo kwendawo.
4. I-Diethylene Glycol Kufanele Igcinwe Futhi Iphathwe Kanjani Ngokuphepha?
Imikhuba efanele yokugcina nokuphatha ibalulekile ekunciphiseni izingozi.
Iziqondiso Zokugcina
• Gcina endaweni epholile, eyomile, futhi enomoya omuhle.
• Gcina izitsha zivaliwe kahle uma zingasetshenziswa.
• Gwema ukuthintana nezinto eziqinisa i-oxidizing.
• Sebenzisa izindlela ezifanele zokuvimbela ukuchitheka.
Imishini Yokuzivikela Yomuntu Siqu (i-PPE)
Lapho bephatha i-DEG, abasebenzi kufanele bagqoke:
• Amagilavu amelana namakhemikhali
• Izibuko zokuphepha noma izihlangu zobuso
• Izingubo zokuzivikela
• Ukuvikelwa okufanele kokuphefumula lapho umoya ungangeni kahle
Ukuphepha Emsebenzini
• Qinisekisa ukuthi umoya ungena ngokwanele ezindaweni zokusebenza.
• Gwema ukuthintana kwesikhumba isikhathi eside kanye nokuhogela umusi.
• Faka iziteshi zokuhlanza amehlo eziphuthumayo kanye nezindawo zokugeza eziphephile lapho kudingeka khona.
Impendulo Ephuthumayo
•Ukuthintana Kwamehlo:Hlanza ngokushesha ngamanzi amaningi bese ucela usizo lwezokwelapha.
•Ukuthintana Kwesikhumba:Geza kahle ngensipho namanzi.
•Ukungenisa:Funa usizo lwezokwelapha ngokushesha futhi wazise abahlinzeki bezempilo ukuthi kusolwa ukuthi kukhona ukuchayeka kwe-diethylene glycol.
•Ukuphefumula:Hambisa umuntu othintekile emoyeni omusha bese uthola usizo lwezokwelapha uma izimpawu ziqhubeka.
5. Uyini Umehluko Phakathi kwe-Diethylene Glycol, i-Ethylene Glycol, kanye ne-Propylene Glycol?
Lawa ma-glycol amathathu avame ukudideka, kodwa ahluke kakhulu ngobuthi kanye nokusetshenziswa kwawo.
I-Ethylene Glycol (EG)
• Isetshenziswa kakhulu ekuvimbeleni ukuqandisa kwezimoto kanye nasekukhiqizeni kwezimboni.
• Kunobuthi obukhulu uma kugwinywa.
I-Diethylene Glycol (DEG)
• Isetshenziswa kabanzi njengesinyibilikisi sezimboni kanye nesiphakathi samakhemikhali.
• Ngokuvamile kubhekwa njengobuthi kakhulu kunezinye izakhi eziningi ze-glycol.
• Akufanelekile ukusetshenziswa kokudla, iziphuzo, noma imithi.
I-Propylene Glycol (PG)
• Ubuthi obuphansi kakhulu.
• Ivame ukusetshenziswa emikhiqizweni yokudla, izimonyo, imithi, kanye nezinto zokunakekela umuntu siqu.
Ukuqonda lo mehluko kubalulekile ekuvimbeleni ukusetshenziswa kabi ngengozi nokuqinisekisa ukuphepha komkhiqizo.
6. Yimiphi Imithetho Elawula i-Diethylene Glycol?
Emazweni amaningi, i-diethylene glycol ilawulwa njengekhemikhali eyingozi.
Abakhiqizi, abasabalalisi, abathuthi, kanye nabasebenzisi ngokuvamile kudingeka:
• Landela imithethonqubo yokuphepha kwamakhemikhali.
• Nikeza amalebula afanele kanye nama-Safety Data Sheets (SDS).
• Sebenzisa izinhlelo zokuqeqesha abasebenzi.
• Gcina izinqubo zokuphendula eziphuthumayo.
Ngaphansi kweUhlelo Lomhlaba Wonke Lokuhlukaniswa Nokulebula Amakhemikhali (i-GHS), i-DEG ihlukaniswa ngokwezingozi zayo zempilo nezemvelo, idinga izinyathelo ezifanele zokuxhumana ngezingozi.
7. Imibono Engalungile Evamile Mayelana ne-Diethylene Glycol
Umbono Ongaqondile 1: I-DEG Ingasetshenziswa Njengesithasiselo se-Propylene Glycol Emikhiqizweni Yokudla
Iqiniso:I-Diethylene glycol inobuthi futhi akumelwe isetshenziswe ekudleni, eziphuzweni, noma emithini eyenzelwe ukusetshenziswa ngabantu.
Umbono Oyiphutha 2: I-DEG Iphephile Ngoba Iyahwamuka Kancane Kancane
Iqiniso:Nakuba i-DEG inokuguquguquka okuphansi kunezinye izinyibilikisi, ukuchayeka emisipheni, ekungcoleni, noma ekuthinteni koketshezi kusengabangela izingozi empilweni.
Umbono Oyiphutha 3: Inani Elincane Lokudalulwa Alinangozi
Iqiniso:Ukuchayeka okuphindaphindiwe noma okwandayo kungaholela emiphumeleni emibi empilweni. Kufanele kulandelwe izinyathelo zokuzivikela ezifanele ngaso sonke isikhathi.
Isiphetho
I-Diethylene glycol iyikhemikhali ebalulekile yezimboni enezinhlobo eziningi zokusetshenziswa, kusukela ezincibilikisini kanye nezipholile kuya ekukhiqizweni kwamakhemikhali. Kodwa-ke, ubuthi bayo kanye nomthelela ongaba khona emvelweni kwenza ukuphathwa kahle, ukugcinwa, kanye nokuhambisana nemithetho kubalulekile.
Ngokuqonda izakhiwo, izingozi, kanye nezidingo zokuphepha ezihambisana ne-DEG, amabhizinisi nabasebenzi banganciphisa izingozi, bavikele impilo yabantu, futhi basekele imisebenzi yezimboni ephephile neqhubekayo.
