I-Ethylene glycol tertiary butyl ether (ETB): I-organic chemical material, uketshezi olungenambala nolubonisa ngale oluvutha umlilo olunokunambitheka kwe-mint. I-Soluble kuma-solvents amaningi e-organic, ingancibilikisa i-amino, i-nitro, i-alkyd, i-acrylic nezinye izinhlaka. Emazingeni okushisa asekamelweni (25 ° C), kungaxubana namanzi, ubuthi obuphansi, ukucasuka okuphansi. Ngenxa yemvelo yayo eyingqayizivele ye-hydrophilic kanye nekhono lokuhlakaza i-fusion, ngakho-ke inomkhuba obanzi wokuthuthukiswa emkhakheni wezingubo zokuvikela imvelo namandla amasha.

Isebenzisa:I-Ethylene glycol tertiary butyl ether, enye indlela eyinhloko ye-ethylene glycol butyl ether, ngokuphambene, iphunga eliphansi kakhulu, ubuthi obuphansi, ukusabela okuphansi kwe-photochemical, njll., ukucasuka kwesikhumba okuthambile, nokuhambisana namanzi, ukuzinza kokuhlakazeka kwepende ye-latex Ukuhambisana okuhle ama-resin amaningi nama-solvents ephilayo, kanye ne-hydrophilicity enhle. Ingasetshenziswa kabanzi emikhakheni eminingi efana ne-coating, inki, i-ejenti yokuhlanza, i-fiber wetting agent, i-plasticizer, i-organic synthesis intermediate kanye nesikhiphi sikapende. Ukusetshenziswa kwayo okuyinhloko kungokulandelayo:
1. Ai-solvent ye-queous enamathela: ikakhulukazi amasistimu anamanzi ancibilikayo, upende wemboni kapende we-latex ohlakazeka ngamanzi. Ngenxa yokuthi inani le-HLB le-ETB lisondele ku-9.0, umsebenzi walo ohlelweni lokuhlakaza udlala indima njenge-dispersant, emulsifier, i-rheological agent kanye ne-cosolvent. Isebenza kahle ngopende we-latex, i-colloidal dispersion coating kanye nokuncibilika kwe-aqueous resin enamathelayo emanzini. , Ngopende wangaphakathi nangaphandle ezakhiweni, i-primer yezimoto, i-tinplate yombala nezinye izinkambu.
2. Pi-aint solvent
2.1Njengomuntu ohlakazekayo. Ukukhiqizwa kopende okhethekile omnyama we-acrylic omnyama nokhethekile, upende we-acrylic ngokuvamile kudinga isikhathi esiningi ukuze ugaye umbala we-pigment omnyama ukuze ufinyelele ubuhle obuthile, kanye nokusetshenziswa kwe-ETB efakwe i-pigment ephezulu ye-carbon black, isikhathi sokugaya singancishiswa ngaphezu kwesigamu, futhi ngemva kokuqeda Ukubukeka kopende bushelelezi futhi bushelelezi.
2.2Njenge-ejenti yokulinganisa i-defoamers, thuthukisa isivinini sokumisa upende wokuhlakazeka kwamanzi, ubushelelezi, isicwebezelisi, ukushesha kokunamathela. Ngenxa yesakhiwo sayo se-tert-butyl, sinokuzinza okuphezulu kwe-photochemical nokuphepha, kungaqeda amaphinikhodi efilimu kapende, izinhlayiya ezincane namabhamuza. Izembatho zamanzi ezenziwe nge-ETB zinokuzinza okuhle kwesitoreji, ikakhulukazi ngaphansi kwezimo eziphansi zokushisa ebusika.
2.3Thuthukisa isicwebezelisi. I-ETB esetshenziswa kupende we-amino, upende we-nitro, ukuvimbela ukukhiqizwa "kwekhasi lewolintshi" -njengezimpawu, isicwebezelisi sefilimu kapende senyuke ngo-2% kuya ku-6%.
3. Ii- nk dispersantI-ETB esetshenziswa njenge-solvent ye-inki eyenziwe, noma njenge-disperant ehlanjululwe esetshenziselwa ukuphrinta oyinki, ungathuthukisa kakhulu i-rheology ye-inki, uthuthukise ikhwalithi yokuphrinta ngesivinini esikhulu kanye nesicwebezelisi, ukunamathela.
4. Fi-ejenti yokukhipha i-iberI-US Alied-Signal Company yafinyelela ku-76% kawoyela wamaminerali aqukethe imicu ye-polyethylene ekhishwa nge-ETB, ngemva kokukhipha uwoyela we-mineral fiber kwehle ngo-0.15%.
5. Udayi we-Titanium Dioxide phthalocyanineInkampani yaseJapan Canon eya ku-Ti (OBu) 4-amino-1,3-isoindoline yesisombululo se-ETB yanyakaziswa ngo-130 ℃ 3h, yathola udayi we-titanium omsulwa we-Phthalocyanine ongu-87%. Futhi i-crystalline oxytitanium phthalocyanine eyenziwe nge-porous titanium oxide phthalocyanine kanye ne-ETB ingasetshenziswa njengesithombe se-photosensitizer ezwela kakhulu ekukhanyeni kwamaza amade.
6. Isihlanzi sasekhaya esisebenzayoU-Asahi Denko uphathwe nge-propylene oxide kanye nomkhiqizo wokusabela oqukethe i-KOH ETB thola i-poly propylene oxide mono-t-butyl ether, eyisihlanzi sasekhaya esikahle nesisebenzayo.
7. I-anti-corrosion paint i-hydrosolI-Nippon Paint Company ene-diethyl ether, i-acrylic resin, i-ETB, i-butanol, i-TiO2, i-cyclohexyl ammonium carbonate, i-ejenti evimbela ukugwaza ukuze ilungise upende ofuthayo wokugqwala wamanzi e-sol.
8. I-carbon film resistor yezingxenye zomsakazonge-ETB njengokumelana ne-liquid carbon film resistors, indawo ebushelelezi, ingaqeda iphinifa kanye ne-negative webbbing futhi ithuthukise ukusebenza kwezingxenye zikagesi.
9. I-Fuel Auxiliary
I-ETB ingasetshenziswa njenge-co-solvent kanye ne-modifier ku-boiler fuels entsha, hhayi nje ukuthuthukisa ukusebenza kahle komlilo, kodwa futhi ukunciphisa ukukhishwa, njengomthombo wamandla omusha wama-boilers nezinjini ezinkulu ze-diesel zasolwandle, kunezidingo eziqinile zemvelo kanye nezinzuzo ze-dividend yenqubomgomo.
