1. Izici:
Ukubukeka kwangaphandle kanye nesimo somzimba: I-Diethylene glycol monobutyl ether (DEGBE) iwuketshezi olucwebezelayo olungenambala olunephunga elincane elijwayelekile le-butyl. Itholakala ngezinhlobo ezahlukene (ezobuchwepheshe ≥99%, i-reagent, ukuhlanzeka okuphezulu).
Ukuncibilika: I-DEGBE ixubana ngokuphelele namanzi, i-ethanol, i-ether, i-acetone kanye nezincibilikisi eziningi eziphilayo, kufaka phakathi i-benzene namafutha. Ubunjalo bayo obukabili be-hydrophilic (utshwala/i-ether) kanye ne-lipophilic (i-butyl) ivumela ukuncibilika kwezinhlobonhlobo zezinto ezi-polar nezingezona i-polar, kufaka phakathi i-nitrocellulose, amafutha, odayi, ama-resin kanye nama-polymer.
Izici zamakhemikhali: I-DEGBE iyi-glycol ether enezinga lokushisa eliphezulu lokubila. Inezinga lokushisa lokubila elingu-230–231°C kanye nezinga lokushisa lokuvutha elingu-99–100°C (isitsha esivaliwe), okwenza kube isincibilikisi esivuthayo kodwa esiphephile uma kuqhathaniswa nezinhlelo zokushisa okuphezulu. Ijubane layo lokuhwamuka elinensayo liyenza ibe i-coalescing agent ephumelelayo kanye ne-leveling agent ezinhlakeni zokumboza. Umhwamuko usinda kunomoya. Into iyazinzile ngamakhemikhali, kodwa ingakha ama-peroxide aqhumayo uma ihlangana nomoya isikhathi eside futhi isabela nama-oxidizing agents anamandla.
2. Ukusetshenziswa:
Украски, izinto zokumboza kanye nokudweba okushicilelwayo (okuyinhloko): I-DEGBE isetshenziswa kabanzi njenge-ejenti yokuhlanganisa (i-film former) kumapende asuselwa emanzini kanye nezingubo ze-emulsion. Ixhazulula i-nitrocellulose, i-alkyd, i-acrylic kanye ne-epoxy resins. Isetshenziswa kuma-lacquers, ama-drying oils, ama-enamels, ama-wood stains, kanye namapende okunyathelisa. Isebenza njengesithuthukisi sendawo yama-enamels okushisa okuphezulu.
Ukuhlanza kwezimboni nasekhaya: I-DEGBE iyisisekelo esibalulekile sezinto zokuhlanza zezimboni nezasekhaya, izinto zokukhipha amafutha, izinto zokugeza upende kanye nezinto zokuhlanza insimbi. Isusa uwoyela, amafutha kanye namagrisi ezingxenyeni zensimbi.
Ukuhlanganiswa kwamakhemikhali kanye ne-semiproducts: Isebenza njengomkhiqizo wangaphakathi ekukhiqizeni ama-plasticizer, isihlukanisi se-vinyl chloride resins, isincibilikisi sokukhipha emithini kanye ne-reagent ku-organic synthesis.
Ezinye izinhlelo zokusebenza: Isihlukanisi samanzi eziqhuba ngamandla emabhuleki, isigxilisi semulsion, isimanzi, into esebenza ebusweni, isincibilikisi kwezimonyo kanye nama-aromatics (FEMA 2362).
3. Indlela yokukhiqiza:
Inqubo yezimboni: I-DEGBE itholakala ngokusabela kwe-ethylene oxide ne-ethylene glycol monobutyl ether. Umkhiqizo uhlanjululwa nge-rectification kuze kufike ekuhlanzekeni okungu-≥99%.
4. Ulwazi lokuphepha:
Ukuhlukaniswa kwengozi: I-DEGBE ihlukaniswa njengoketshezi oluvuthayo. Iqukethe isikhombisi sengozi: H319 (Ibanga umonakalo omkhulu emehlweni). Igama lesignali: Qaphela. NFPA 704: Ingozi yezempilo 1, Ukusha 1, Ukungazinzi 0. Ukuhlukaniswa kwe-EC: Xi; R: 36.
Izingozi zempilo: Kubangela ukucasuka kwamehlo. Uma kuthintana isikhathi eside nesikhumba kungabangela ukuphela kwamafutha nokoma. Uma kuhogela umusi kungabangela ukucasuka okuncane kwemigudu yokuphefumula.
Izinyathelo zosizo lokuqala: Uma kungena emehlweni – geza ngamanzi; esikhumbeni – geza ngamanzi nensipho; uma kuhogela – umoya omusha; uma kugwinya – hlambulula umlomo, UNGAHLANZI, bheka udokotela.
Ingozi yomlilo nokuqhuma: Uketshezi oluvuthayo (izinga lokushisa lokuvutha 99–100°C). Ngaphezu kuka-78°C umusi ungakha izingxube eziqhumayo nomoya. Into ingakha ama-peroxide. Emlilweni sebenzisa amanzi afafazayo, igwebu, impushana noma i-CO₂.
Ukugcinwa nokuzinza: Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile, enomoya omuhle. Isikhathi sokusebenza: izinyanga ezingama-24–60 ezitsheni zokuqala ezivaliwe.
Ukuhambisana nomthetho: I-DEGBE (CAS#112-34-5, EC#203-961-6) ifakiwe kumarejista e-EINECS, TSCA, DSL. Ilawulwa yi-ACGIH (TLV: 10 ppm). Ukuze uthole ulwazi oluphelele, bheka i-Safety Data Sheet (SDS).
