I-Triethylene Glycol Butyl Ether

Isinyibilikisi esisebenza kahle kakhulu nesinobungani nemvelo, esinika amandla ukuthuthukiswa kwekhwalithi ezimbonini eziningi

I-Diethylene Glycol Butyl Ether (igama lamakhemikhali: I-Diethylene Glycol Monobutyl Ether, igama lesiNgisi: I-Diethylene Glycol Butyl Ether, elifushaniswe ngokuthi i-DGBE) iyisinyibilikisi sezinto eziphilayo esisebenza ngezindlela eziningi esinamandla okuncibilikisa kahle, ukuzinza okuhle kakhulu, kanye nokuphepha kwemvelo. Ngezici zayo eziyinhloko zokubilisa okuphezulu, ukuguquguquka okuphansi, kanye nokuncibilika kokubili emanzini nasemafutheni, kanye nezinzuzo eziluhlaza zobuthi obuphansi kanye nokukhishwa okuphansi kwe-VOC, i-DGBE isibe yisithasiselo esiyinhloko emikhakheni ehlukahlukene efana nokugqoka, uyinki, ukuhlanza kwezimboni, izinto zikagesi, kanye nemithi. Ingathatha indawo ngokunembile izinyibilikisi zendabuko ezinokungcola okuphezulu, isize amabhizinisi ukufeza imigomo eminingi yokwenza ngcono ifomula, ukuthuthukisa ukusebenza kahle, kanye nokuthuthukisa ukuhambisana nemithetho.

Ukusebenza Okuyinhloko: Izinzuzo eziningi, ezichaza izinga lokusebenza okusha kwe-solvent

1. Iphuzu lokubila eliphezulu kanye nokuguquguquka okuphansi, okwenza ukwakhiwa kanye nokukhiqiza kuzinze kakhudlwana

I-DGBE inezinga lokubila elifinyelela ku-230°C kanye nezinga lokushaqeka elivaliwe elingu-78°C, elinezinga lokushaqeka elihamba kancane nelilinganayo. Ezimweni ezifana nokwakhiwa kwezinga lokushisa eliphezulu kanye nokubhaka isikhathi eside, ingalungisa ngempumelelo ijubane lokomisa lesistimu, igweme amaphutha afana nekhasi le-orange, ama-pinhole, kanye nokumhlophe kwefilimu yokumboza okubangelwa ukushaqeka okusheshayo kwezinyibilikisi. Ngesikhathi esifanayo, ukwakheka kwe-flash point ephezulu kunciphisa kakhulu izingozi zokuphepha ngesikhathi sokukhiqiza nokugcina, kuvumelana nezidingo ezahlukene zokukhiqiza ezinkulu zezimboni.

2. Amandla okuncibilikisa anobubanzi, ukuzivumelanisa nezimo okunamandla kokubili emanzini namafutha

Inezakhiwo ezinhle kakhulu ze-amphiphilic (zombili ezihlala emanzini kanye ne-lipophilic), futhi ingancibilikisa ngempumelelo izinto ezahlukahlukene ezifana ne-resin (i-acrylic resin, i-epoxy resin, i-alkyd resin, njll.), i-nitrocellulose, amafutha, udayi, namafutha amaminerali. Ingaxutshwa namanzi nganoma iyiphi indlela futhi ihambisane ngokuphelele nezinyibilikisi eziphilayo ezifana ne-ethanol, i-acetone, ne-toluene. Ingashintshwa ngqo ngaphandle kokulungiswa okuphawulekayo kumafomula akhona, okunciphisa kakhulu izindleko zokuthuthukisa ifomula yebhizinisi.

3. Okuluhlaza, okuphephile, nokuthobela imithetho, okuhambisana nomkhuba wokuthuthukiswa kokuvikelwa kwemvelo

Uma ukhiqizwa kusetshenziswa inqubo yokwenziwa kwe-catalytic eluhlaza, umkhiqizo uhlanzekile okungu-≥99.5% kanye nokuqukethwe kokungcola okuphansi kakhulu. Unobuthi obuncane, kanti ubuthi buncishiswe ngaphezu kuka-75% uma kuqhathaniswa nezinyibilikisi zendabuko (njenge-ethylene glycol ethers) kanye nokukhishwa kwe-VOC kuncishiswe ngo-90%. Ungahlangabezana kalula nemithetho eqinile yezemvelo yasekhaya neyakwamanye amazwe efana ne-GB, REACH, kanye ne-TSCA, okusiza amabhizinisi ukuthi adlule ezithiyweni zokuhweba eziluhlaza.

4. Ukusebenza kahle kakhulu kokuhlanganisa, okuthuthukisa ukuzinza kohlelo

Inomsebenzi omuhle wokuhlanganisa nokuzinzisa, okungathuthukisa ngempumelelo ukuhambisana kwezinhlelo ezixubile, kuvimbele ukuhlukaniswa kwefomula kanye nokuna kwemvula, futhi kwandise isikhathi sokugcina umkhiqizo. Uma ingezwa emikhiqizweni efana nezinto zokuhlanza kanye nezingubo, ingathuthukisa kakhulu ikhono lokuhlanza, ikhwalithi yokwakha ifilimu, kanye nokumelana nesimo sezulu sohlelo, kufezwe ukwenziwa ngcono okuphelele kokusebenza komkhiqizo.
