I. Intshayelelo emfutshane yeMveliso: Isinyibilikisi esiBilisa kakhulu esisebenza kakuhle
I-Diethylene Glycol Monobutyl Ether, edla ngokufinyezwa njenge-DEGMBE okanye i-BDG, sisinyibilikisi sendalo esingenambala, esicacileyo esinevumba elithambileyo elifana ne-butanol. Njengelungu eliphambili losapho lwe-glycol ether, isakhiwo sayo se-molecular siqulathe iibhondi ze-ether kunye namaqela e-hydroxyl, esinika iipropati ezikhethekileyo ze-physicochemical ezenza ukuba ibe sisinyibilikisi esiguquguqukayo nesiphakathi ukuya phezulu.
Amandla aphambili e-DEGMBE akwindlela yayo yokunyibilika engaqhelekanga kunye namandla okudibanisa. Ibonisa amandla aqinileyo okusombulula iingxaki ezahlukeneyo ze-polar kunye ne-non-polar, ezifana nee-resins, ii-oyile, iidayi, kunye ne-cellulose. Okubaluleke ngakumbi, i-DEGMBE isebenza njenge-coupling agent, evumela iinkqubo ezingahambelaniyo ekuqaleni (umz., amanzi kunye ne-oyile, ii-organic resins kunye namanzi) ukuba zenze izisombululo ezizinzileyo, ezifanayo okanye ii-emulsions. Olu phawu lubalulekileyo, ludibene nesantya sayo sokuphuma kwamanzi esiphakathi kunye nepropati entle yokulinganisa, lubeka isiseko sezicelo ezibanzi ze-DEGMBE kwezi ndawo zilandelayo:
●Ishishini leeCoatings kunye neeInki: Lisetyenziswa njengesinyibilikisi kunye nearhente yokudibanisa kwiipeyinti ezisekelwe emanzini, iipeyinti zelatex, iipeyinti zokubhaka zemizi-mveliso, kunye nee-inki zokuprinta, liphucula ngokufanelekileyo ukulingana kwefilimu kunye nokukhazimla ngelixa lithintela ukuqhekeka kwefilimu kumaqondo obushushu aphantsi.
●Ii-Cleaners & Paint Stripers: I-DEGMBE, eyona nto ibalulekileyo kwii-cleaners ezininzi zemizi-mveliso ezisebenza kakuhle, ii-degreasers, kunye nee-paint strippers, inyibilikisa ii-oyile kunye neefilimu zepeyinti ezindala ngempumelelo.
●Ukulungiswa Kwempahla Nesikhumba: Isebenza njengesinyibilikisi sedayi kunye nezinye izinto ezincedisayo, inceda ukungena ngokulinganayo.
●Iikhemikhali ze-elektroniki: Zisebenza kwii-strippers ze-photoresist kunye nezinye izisombululo zokucoca nge-elektroniki.
●Eminye iMimandla: Isetyenziswa kwizibulali-zinambuzane, ulwelo lokusebenza ngesinyithi, izincamathelisi ze-polyurethane, nokunye.
Ngoko ke, nangona i-DEGMBE ingenzi ngqo umzimba oyintloko wezinto ezifana nee-bulk monomers, isebenza njenge-"MSG yezimboni" ebalulekileyo - idlala indima engenakutshintshwa ekuphuculeni ukusebenza kwemveliso kunye nokuzinza kwenkqubo kumashishini amaninzi asezantsi.
II. Iindaba Zamva nje: Imakethi Engaphantsi Kwemfuno Engqongqo Yokubonelela Ngempahla Neendleko Eziphezulu
Kutshanje, ngokuchasene notshintsho lweenkqubo zoshishino zehlabathi kunye nokuguquguquka kwezinto eziluhlaza, imakethi ye-DEGMBE ibonakaliswe kukungabikho kobonelelo oluqinileyo kunye namaxabiso aphezulu.
Ukuguquguquka kwe-Ethylene Oxide yezinto eziluhlaza okwesibhakabhaka kunika inkxaso enamandla
Izinto eziphambili zemveliso ye-DEGMBE yi-ethylene oxide (EO) kunye ne-n-butanol. Ngenxa yokuba i-EO inokutsha kwaye iqhuma, umthamo wayo wokujikeleza kwezorhwebo ulinganiselwe, kunye nomahluko omkhulu wamaxabiso engingqi kunye nokuguquguquka rhoqo. Kutshanje, imakethi ye-EO yasekhaya ihlale ikwinqanaba eliphezulu lamaxabiso, iqhutywa ziindlela ze-ethylene ezinyukayo kunye nokuguquguquka kwayo kwemfuno yokubonelela, okwenza inkxaso eqinileyo yeendleko ze-DEGMBE. Nakuphi na ukutshintsha kwimakethi ye-n-butanol nako kudluliselwa ngqo kumaxabiso e-DEGMBE.
Ubonelelo Oluqinileyo Oluhlala Luhleli
Kwelinye icala, ezinye izakhiwo ezinkulu zemveliso ziye zavalwa ngendlela ecwangcisiweyo okanye engacwangciswanga ukuze zilungiswe kwixesha elidlulileyo, nto leyo echaphazela ukubonelelwa kweendawo zokuthengisa. Kwelinye icala, uluhlu lwezinto ezithengiswayo kushishino luhlala lusezantsi. Oku kukhokelele ekunqongophaleni kweendawo zokuthengisa i-DEGMBE kwimarike, apho abanini bezakhiwo begcina izimvo zabo zokucaphula.
Imfuno Eyahlukileyo Ephantsi
Njengecandelo elikhulu lokusetyenziswa kwe-DEGMBE, imfuno yeshishini leengubo inxulumene ngokusondeleyo nokuchuma kwezindlu kunye nokwakhiwa kweziseko zophuhliso. Okwangoku, imfuno yeengubo zokwakha isazinzile, ngelixa imfuno yeengubo zoshishino (umz., iimoto, iinqanawa, kunye neengubo zesikhongozeli) inika amandla athile kwimarike ye-DEGMBE. Imfuno kwiindawo zemveli ezifana nabacoci ihlala izinzile. Ukwamkelwa kwabathengi abasezantsi kwe-DEGMBE enexabiso eliphezulu kuye kwaba yeyona nto iphambili kwimidlalo yemarike.
III. Iindlela Zoshishino: Ukuphuculwa Kwendalo Esingqongileyo kunye noPhuhliso Olucociweyo
Ukujonga phambili, uphuhliso lweshishini le-DEGMBE luya kudityaniswa kakhulu nemithetho yokusingqongileyo, inkqubela phambili kwezobuchwepheshe, kunye notshintsho kwimfuno yemarike.
Iingxoxo zoPhuculo kunye noTshintsho lweMveliso eziqhutywa yiMimiselo yokusingqongileyo
Ezinye izinyibilikisi ze-glycol ether (ingakumbi i-E-series, efana ne-ethylene glycol methyl ether kunye ne-ethylene glycol ethyl ether) zithintelwe ngokungqongqo ngenxa yeengxaki zobuthi. Nangona i-DEGMBE (ehlelwe phantsi kwe-P-series, oko kukuthi, i-propylene glycol ethers, kodwa ngamanye amaxesha ixutyushwa kwiindidi zemveli) inetyhefu ephantsi kwaye isetyenziswa ngokubanzi, umkhwa wehlabathi we-"green chemistry" kunye nokunciphisa ukukhutshwa kwe-VOC (Volatile Organic Compounds) kubeke uxinzelelo kulo lonke ishishini le-solvent. Oku kuqhubele phambili i-R&D kwezinye iindlela ezinobuhlobo nokusingqongileyo (umz., ii-propylene glycol ethers ezithile) kwaye kwabangela i-DEGMBE ngokwayo ukuba iphuhlise ukuya kubumsulwa obuphezulu kunye namanqanaba aphantsi okungcola.
Ukuphuculwa Kwemizi-mveliso Okukhokelela Ekuphuculeni Imfuno
Uphuhliso olukhawulezileyo lweengubo zoshishino eziphezulu (umz., iipeyinti zoshishino ezisekelwe emanzini, iingubo eziqinileyo), ii-inki ezisebenzayo eziphezulu, kunye neekhemikhali ze-elektroniki ziye zabeka iimfuno ezingqongqo ngakumbi kubunyulu be-solvent, uzinzo, kunye nezinto eziseleyo. Oku kufuna ukuba abavelisi be-DEGMBE baqinise ulawulo lomgangatho kwaye banikezele ngeemveliso ze-DEGMBE ezenzelwe wena okanye ezikumgangatho ophezulu ezihlangabezana neemfuno ezithile zesicelo esikumgangatho ophezulu.
Utshintsho kwiPatheni yoMgangatho weMveliso yeSithili
Umthamo wemveliso ye-DEGMBE kwihlabathi liphela ugxile kakhulu eTshayina, eMntla Melika, eNtshona Yurophu, nakwezinye iindawo zaseAsia. Kwiminyaka yakutshanje, amandla emveliso kunye nempembelelo yeTshayina iqhubekile nokunyuka, ixhaswa luchungechunge olupheleleyo lwemizi-mveliso kunye nemarike enkulu esezantsi. Kwixesha elizayo, uyilo lwamandla emveliso luya kuqhubeka lusondela kwiimarike ezinkulu zabathengi, ngelixa iindleko zokusingqongileyo kunye nokhuseleko ziya kuba zizinto eziphambili ezichaphazela ukhuphiswano lwengingqi.
Ukuphuculwa kweNkqubo kunye nokuHlanganisa iCandelo leMizi-mveliso
Ukuphucula ukhuphiswano lweendleko kunye nokuzinza kobonelelo, abavelisi abaphambili bathambekele ekwenzeni ngcono iinkqubo zemveliso ze-DEGMBE ngokuphucula ubuchwepheshe, ukwandisa ukusetyenziswa kwezinto eziluhlaza kunye nemveliso. Okwangoku, amashishini anomthamo odibeneyo wemveliso ye-ethylene oxide okanye i-alcohols anenzuzo enamandla yokumelana nomngcipheko kukhuphiswano lwemarike.
Ngamafutshane, njengesisombululo esisebenzayo, imakethi ye-DEGMBE inxulumene ngokusondeleyo namacandelo okuvelisa asezantsi afana neengubo kunye nokucoca—esebenza njenge-"barometer" yokuchuma kwabo. Ijongene nemingeni emibini yoxinzelelo lweendleko zezinto eziluhlaza kunye nemithetho yokusingqongileyo, imboni ye-DEGMBE ifuna amathuba amatsha okulinganisela kunye nophuhliso ngokuphucula umgangatho wemveliso, ukuphucula amakhonkco okubonelela, kunye nokuziqhelanisa neemfuno eziphezulu ezisezantsi, ukuqinisekisa ukuba esi "sisombululo esiguquguqukayo" siyaqhubeka nokudlala indima yaso ebalulekileyo kwinkqubo yemizi-mveliso yanamhlanje.
