I. Isingeniso Esifushane Somkhiqizo: Isinyibilikisi Esibilisa Kakhulu Esisebenza Kakhulu
I-Diethylene Glycol Monobutyl Ether, evame ukufushaniswa ngokuthi i-DEGMBE noma i-BDG, iyi-solvent ephilayo engenambala, ecacile enephunga elifana ne-butanol. Njengelungu elibalulekile lomndeni we-glycol ether, isakhiwo sayo sama-molecule siqukethe izibopho ze-ether namaqembu e-hydroxyl, okwenza kube yi-"solvent" eyingqayizivele eyenza ibe "solvent eguquguqukayo" enhle kakhulu ephakathi kuya phezulu, eguquguqukayo kancane.
Amandla ayinhloko e-DEGMBE atholakala ekuncibilikeni kwayo okumangalisayo kanye namandla okuhlanganisa. Ibonisa amandla aqinile ezinto ezahlukahlukene ze-polar kanye nezingezona ze-polar, njenge-resin, uwoyela, udayi, kanye ne-cellulose. Okubaluleke kakhulu, i-DEGMBE isebenza njenge-ejenti yokuhlanganisa, okwenza izinhlelo ezingahambisani ekuqaleni (isb., amanzi namafutha, ama-resin e-organic namanzi) zakhe izixazululo ezizinzile, ezifanayo noma ama-emulsion. Lesi sici esibalulekile, esihlanganiswe nesilinganiso sayo sokuhwamuka esimaphakathi kanye nesici esihle kakhulu sokulinganisa, sibeka isisekelo sezinhlelo ze-DEGMBE ezisabalele kule mikhakha elandelayo:
●Imboni Yezimbozo Nama-Ink: Isetshenziswa njenge-solvent kanye ne-coalescing ependini ezisekelwe emanzini, opende be-latex, opende bokubhaka bezimboni, kanye noyinki wokunyathelisa, ithuthukisa ngempumelelo ukulingana kwefilimu kanye nokucwebezela ngenkathi ivimbela ukuqhekeka kwefilimu emazingeni okushisa aphansi.
●Abahlanzi Neziqeshana Zokupenda: I-DEGMBE, ingxenye ebalulekile ezihlanzini eziningi zezimboni ezisebenza kahle, iziqeshana zokususa amafutha, kanye neziqeshana zokupenda, incibilikisa kahle amafutha namafilimu amadala okupenda.
●Ukucubungula Izindwangu Nesikhumba: Kusebenza njengesithako sodayi kanye nezinto ezisizayo, okwenza kube lula ukungena ngokulinganayo.
●Amakhemikhali E-elekthronikhi: Asebenza kuma-stripper e-photoresist kanye nezixazululo ezithile zokuhlanza ze-elekthronikhi.
●Eminye Imikhakha: Isetshenziswa ezibulala-zinambuzane, uketshezi lokusebenza ngensimbi, izinamathiseli ze-polyurethane, nokuningi.
Ngakho-ke, yize i-DEGMBE ingakhi ngokuqondile umzimba oyinhloko wezinto ezifana nama-bulk monomers, isebenza njenge-"MSG yezimboni" ebalulekile - idlala indima engenakuphikwa ekuthuthukiseni ukusebenza komkhiqizo kanye nokuzinza kwenqubo kuzo zonke izimboni eziningi ezingezansi.
II. Izindaba Zakamuva: Imakethe Engaphansi Kwesidingo Esiqinile Sokunikezwa Kwempahla kanye Nezindleko Eziphezulu
Muva nje, ngenxa yokulungiswa kweketanga lezimboni emhlabeni jikelele kanye nokuguquguquka kwezinto zokusetshenziswa, imakethe ye-DEGMBE ibonakaliswe ukuntuleka kokunikezwa kanye namazinga aphezulu entengo.
Ukuguquguquka kwe-Ethylene Oxide Yezinto Ezingavuthiwe Kunikeza Ukusekelwa Okuqinile
Izinto zokusetshenziswa eziyinhloko zokukhiqiza ze-DEGMBE yi-ethylene oxide (EO) kanye ne-n-butanol. Ngenxa yokuthi i-EO iyasha futhi iyaqhuma, umthamo wayo wokujikeleza kwezentengiselwano ulinganiselwe, kanye nomehluko omkhulu wamanani wesifunda kanye nokuguquguquka okuvamile. Muva nje, imakethe ye-EO yasekhaya ihlale isezingeni eliphezulu lamanani, iqhutshwa yizitayela ze-ethylene ezikhuphukayo kanye nokuguquguquka kwayo kokuhlinzekwa kwezidingo, okwakha ukwesekwa kwezindleko okuqinile kwe-DEGMBE. Noma yikuphi ukuguquguquka emakethe ye-n-butanol nakho kudluliselwa ngqo emananini e-DEGMBE.
Ukunikezwa Okuqinile Okuqhubekayo
Ngakolunye uhlangothi, ezinye izikhungo ezinkulu zokukhiqiza ziye zavalwa ngokuhleliwe noma ngokungahleliwe ukuze zilungiswe esikhathini esidlule, okuthinta ukutholakala kwezindawo. Ngakolunye uhlangothi, isitokwe semboni iyonke sihlale sisezingeni eliphansi. Lokhu kuholele ekushodeni kwezindawo ze-DEGMBE emakethe, lapho abanikazi bezinkampani beqhubeka nokucaphuna izimo zengqondo.
Isidingo Esihlukile Esiphansi
Njengomkhakha wokusetshenziswa omkhulu we-DEGMBE, isidingo semboni yezingubo zokugqoka sihlobene kakhulu nokuchuma kwezindlu kanye nokwakhiwa kwengqalasizinda. Njengamanje, isidingo sezingubo zokugqoka zezakhiwo sisazinzile, kuyilapho isidingo sezingubo zokugqoka zezimboni (isb., izingubo zezimoto, zasolwandle, kanye nezezitsha) sinikeza umfutho othile emakethe ye-DEGMBE. Isidingo emikhakheni yendabuko njengabahlanzi sisazinzile. Ukwamukelwa kwamakhasimende aphansi kwe-DEGMBE ebiza kakhulu sekuyinto ebalulekile emidlalweni yemakethe.
III. Imikhuba Yemboni: Ukuthuthukiswa Kwemvelo kanye Nentuthuko Ecwengisisiwe
Uma sibheka phambili, intuthuko yemboni ye-DEGMBE izoxhunyaniswa eduze nemithethonqubo yezemvelo, intuthuko yezobuchwepheshe, kanye nezinguquko ezidingweni zemakethe.
Izingxoxo Zokuthuthukiswa Komkhiqizo Nokufaka Esikhundleni Esiqhutshwa Yimithetho Yezemvelo
Ezinye izinyibilikisi ze-glycol ether (ikakhulukazi i-E-series, njenge-ethylene glycol methyl ether kanye ne-ethylene glycol ethyl ether) zinqunyelwe ngokuqinile ngenxa yokukhathazeka ngobuthi. Nakuba i-DEGMBE (ehlukaniswe ngaphansi kwe-P-series, okungukuthi, ama-propylene glycol ethers, kodwa ngezinye izikhathi kuxoxwa ngazo ezinhlotsheni zendabuko) inobuthi obuphansi kakhulu kanye nokusetshenziswa okubanzi, umkhuba womhlaba wonke we-"green chemistry" kanye nokukhishwa kwe-VOC (Volatile Organic Compounds) okuncishisiwe kubeke ingcindezi embonini yonke yezinyibilikisi. Lokhu kuqhubekisele phambili i-R&D yezinye izindlela ezinobungani nemvelo (isb., ama-propylene glycol ethers athile) futhi kwashukumisela i-DEGMBE ngokwayo ukuthi ithuthukele ekuhlanzekeni okuphezulu kanye namazinga aphansi okungcola.
Ukuthuthukiswa Kwezimboni Okuholela Ezansi Kuthuthukisa Isidingo
Ukuthuthukiswa okusheshayo kwezimbozo zezimboni ezisezingeni eliphezulu (isb., upende wezimboni osekelwe emanzini, izimbozo eziqinile), uyinki osebenza kahle, kanye namakhemikhali kagesi kuye kwabeka izidingo eziqinile ekuhlanzekeni kwe-solvent, ukuzinza, kanye nezinto ezisele. Lokhu kudinga abakhiqizi be-DEGMBE ukuthi baqinise ukulawulwa kwekhwalithi futhi banikeze imikhiqizo ye-DEGMBE eyenziwe ngokwezifiso noma ecacisiwe kakhulu ehlangabezana nezidingo ezithile zesicelo sezinga eliphezulu.
Izinguquko Ephethini Lokukhiqiza Lesifunda
Umthamo wokukhiqiza we-DEGMBE womhlaba wonke ugxile kakhulu eShayina, eNyakatho Melika, eNtshonalanga Yurophu, nakwezinye izingxenye zase-Asia. Eminyakeni yamuva nje, umthamo wokukhiqiza kanye nethonya laseShayina kuqhubekile nokwenyuka, kusekelwa uchungechunge oluphelele lwezimboni kanye nemakethe enkulu engezansi. Esikhathini esizayo, ukwakheka kwamandla okukhiqiza kuzoqhubeka nokusondela ezimakethe ezinkulu zabathengi, kuyilapho izindleko zemvelo nokuphepha zizoba yizici ezibalulekile ezithinta ukuncintisana kwesifunda.
Ukuthuthukiswa Kwezinqubo kanye Nokuhlanganiswa Kwezinkinobho Zezimboni
Ukuze kuthuthukiswe ukuncintisana kwezindleko kanye nokuzinza kokuhlinzekwa, abakhiqizi abahamba phambili bavame ukwenza ngcono izinqubo zokukhiqiza ze-DEGMBE ngokusebenzisa ukuthuthukiswa kobuchwepheshe, ukwandisa ukusetshenziswa kwezinto zokusetshenziswa kanye nomkhiqizo okhiqizwayo. Okwamanje, amabhizinisi anekhono lokukhiqiza elihlanganisiwe le-ethylene oxide noma i-alcohols anamandla okumelana nengozi emncintiswaneni wemakethe.
Ngamafuphi, njengesixazululo esibalulekile esisebenzayo, imakethe ye-DEGMBE ixhumene kakhulu nemikhakha yokukhiqiza engezansi njengezembozo nokuhlanza—esebenza njenge-"barometer" yokuchuma kwabo. Ibhekene nezinselelo ezimbili zokucindezela izindleko zezinto zokusetshenziswa kanye nemithethonqubo yezemvelo, imboni ye-DEGMBE ifuna amathuba amasha okulinganisela kanye nokuthuthukiswa ngokuthuthukisa ikhwalithi yomkhiqizo, ukwenza ngcono izintambo zokuhlinzeka, kanye nokuzivumelanisa nesidingo esiphezulu esingezansi, ukuqinisekisa ukuthi lesi "sixazululo esiguquguqukayo" siyaqhubeka nokudlala indima yaso ebalulekile ohlelweni lwezimboni lwanamuhla.
