Umhlinzeki we-Butyldiglycol (BDG) eNingizimu Afrika

Kuyini i-Butyldiglycol?

I-Butyldiglycol (BDG), eyaziwa nangokuthi i-diethylene glycol monobutyl ether (DGBE), iyi-glycol ether solvent enomgogodla we-diethylene glycol oqedwa yiqembu le-butyl ether. Iyilungu elilandelayo lochungechunge lwe-butyl glycol ether homologous ngemuva kwe-butyl glycol (ethylene glycol monobutyl ether), eneyunithi eyengeziwe ye-ethyleneoxy eyinika isisindo sama-molecule esiphezulu, iphuzu lokubila eliphakeme (~230°C), izinga lokuhwamuka elihamba kancane, kanye nokuncibilika kwamanzi okuthuthukisiwe uma kuqhathaniswa ne-butyl glycol. I-BDG ixubene ngokuphelele namanzi futhi ixubene nezinyibilikisi eziningi eziphilayo, okwenza kube yi-ejenti yokuhlanganisa eguquguqukayo yezinhlelo okumele zincibilikise izingxenye ze-hydrophilic kanye ne-hydrophobic.

Izicelo Zomkhiqizo Wokuhlanza

Ekuhlanzeni umkhiqizo, i-BDG isebenza ngokuyinhloko njenge-coupler kanye ne-grease solvent kuma-cleaner agxile kuzo zonke izinto, ama-degreasers, kanye nama-hard surface cleaner. Izinga layo lokuhwamuka elihamba kancane uma liqhathaniswa ne-butyl glycol linikeza isikhathi eside sokuhlala ezindaweni ezingcolile, okuthuthukisa ukuncibilika kwamafutha ngaphambi kokuhlanza. I-BDG isebenza kahle kakhulu kuma-concentrate okuhlanza axubile kakhulu lapho inani elincane lezithako ezisebenzayo kufanele likhiqize ikhambi elicacile nelizinzile ebangeni elibanzi lokuxuba. Iphinde isetshenziswe kuma-cleaner ohhavini kanye nama-degreasers asekhishini asebenza kanzima lapho isikhathi eside sokuxhumana kwendawo sibalulekile.

Ukusetshenziswa Nokunikezwa Kopende Nokumboza

Ekumbozeni, i-BDG iyi-ejenti yokuhlanganisa kanye ne-retarder solvent kumapende nama-varnish asekelwe emanzini, ithuthukisa ukwakheka kwefilimu emazingeni okushisa aphansi futhi inciphisa amamaki ebhulashi ezinhlelweni ze-alkyd neze-acrylic. I-Terracore Chemicals inikeza i-BDG yezinga lobuchwepheshe kuma-drum nama-IBC okuhlanza imikhiqizo kanye nabakhiqizi be-coating kulo lonke elaseNingizimu Afrika.
