Iimpawu zomzimba kunye neekhemikhali
I-Ethylene glycol tertiary butyl ether (ETB): Yimathiriyeli yekhemikhali ephilayo, ulwelo olungenambala nolubonakalayo olunokutsha olunencasa yeminti. Inyibilika kwiintlobo ezininzi ze-organic solvents, inokunyibilikisa i-amino, i-nitro, i-alkyd, i-acrylic kunye nezinye ii-resin. Kwiqondo lokushisa lokushisa (25 ° C), unokuxutywa ngamanzi, ubuthi obuphantsi, ukucaphuka okuphantsi. Ngenxa yobume bayo obukhethekileyo be-hydrophilic kunye nokukwazi ukunyibilikisa i-fusion, ngoko inendlela yophuhliso olubanzi kwinkalo yokukhusela indalo kunye namandla amatsha.

Usebenzisa:I-Ethylene glycol tertiary butyl ether, eyona ndlela iphambili ye-ethylene glycol butyl ether, ngokuchaseneyo, ivumba eliphantsi kakhulu, ityhefu ephantsi, i-photochemical reactivity ephantsi, njl. uninzi lweereyini kunye nezinyibilikisi eziphilayo, kunye ne-hydrophilicity elungileyo. Inokusetyenziswa ngokubanzi kwiindawo ezininzi ezifana nokugquma, i-inki, i-agent yokucoca, i-agent yokumanzisa i-fiber, i-plasticizer, i-organic synthesis intermediate kunye ne-remover yepeyinti. Eyona nto isetyenziswayo yile ilandelayo:
1. Aisinyibilikisi sokwaleka: ikakhulu kwiinkqubo zamanzi ezinyibilikayo, ipeyinti yepeyinti yepeyinti yelatex echithwa ngamanzi. Ngenxa yokuba ixabiso le-HLB le-ETB lisondele kwi-9.0, umsebenzi walo kwinkqubo yokusabalalisa idlala indima njenge-dispersant, emulsifier, i-rheological agent kunye ne-cosolvent. Inokusebenza kakuhle kwepeyinti ye-latex, i-colloidal dispersion coating kunye nokunyibilikisa i-aqueous resin coating kwiingubo eziphuma emanzini. , Ngepeyinti yangaphakathi nangaphandle kwizakhiwo, i-primer yeemoto, i-tinplate yombala kunye nezinye iindawo.
2. Paint solvent
2.1Njengomsabalalisi. Ukuveliswa kwepeyinti ye-acrylic emnyama ekhethekileyo kunye neyodwa emnyama, ipeyinti ye-acrylic idla ngokufuna ixesha elininzi kwi-pigment ephezulu ye-pigment emnyama yokusila ukuphumeza ukucoleka okuthile, kunye nokusetyenziswa kwe-ETB efakwe i-pigment ephezulu ye-carbon emnyama, ixesha lokusila lingancitshiswa. ngaphezu kwesiqingatha, kwaye emva kokugqiba Ukubonakala kwepeyinti ilula ngakumbi kwaye ilula.
2.2Njenge-ejenti yokulinganisa i-defoamers, phucula isantya sokumisa ipeyinti yokusasazwa kwamanzi, ukuguda, ukuqaqamba, ukuncamathela ngokukhawuleza. Ngenxa yesakhiwo sayo se-tert-butyl, inozinzo oluphezulu lwe-photochemical kunye nokhuseleko, lunokuphelisa i-pinholes yefilimu yepeyinti, iincinci ezincinci kunye neebhubhu. Iingubo zamanzi ezenziwe nge-ETB zinozinzo oluhle lokugcina, ngakumbi phantsi kweemeko eziphantsi zokushisa ebusika.
2.3Phucula iglosi. I-ETB esetyenziswa kwipeyinti ye-amino, ipeyinti ye-nitro, ukuthintela ukuveliswa kwe-"peel ye-orenji" -efana neempawu, i-gloss yefilimu yepeyinti yanda nge-2% ukuya kwi-6%.
3. Inkqu dispersantI-ETB esetyenziswe njenge-solvent ye-inki eyenziwe, okanye njenge-diluted dispersant esetyenziswa kwii-inki zokuprinta, unokuphucula kakhulu i-rheology ye-inki, uphucule umgangatho wokushicilela ngesantya esiphezulu kunye neglosi, ukunamathela.
4. Fi-arhente yokutsalwa kwe-iberI-US Alied-Signal Company yaya kuma-76% e-oyile yeminerali ene-polyethylene fibers ene-ETB extraction, emva kokutsalwa kwe-oyile ye-mineral fiber yehle nge-0.15%.
5. Idayi ye-Titanium Dioxide phthalocyanineInkampani yaseJapan Canon ukuya kuTi (OBu) 4-amino-1,3-isoindoline yesisombululo se-ETB yavuselelwa kwi-130 ℃ 3h, yafumana i-87% yedayi ecocekileyo ye-titanium Phthalocyanine. Kwaye icrystalline oxytitanium phthalocyanine eyenziwe ngeporous titanium oxide phthalocyanine kunye ne-ETB ingasetyenziswa njengefotosensitizer yefoto enovakalelo oluphezulu kukukhanya kobude obude.
6. Isicoci sasekhaya esisebenzayoU-Asahi Denko uphathwe nge-propylene oxide kunye nemveliso yokusabela equlethe i-KOH ETB ifumana i-poly propylene oxide i-mono-t-butyl ether, eyona nto ifanelekileyo kwaye isebenzayo yokucoca indlu.
7. Ipeyinti yokunqanda ukubola ihydrosolInkampani ye-Nippon Paint ene-diethyl ether, i-acrylic resin, i-ETB, i-butanol, i-TiO2, i-cyclohexyl ammonium carbonate, i-agent anti-foaming ukulungiselela ipeyinti etshizwayo ye-sol corrosion yamanzi.
8. carbon film resistor yamacandelo kanomathotholonge-ETB njenge-liquid carbon film resistors resistance, indawo egudileyo, inokuphelisa i-pinhole kunye ne-negative phenomena webbbing kunye nokuphucula ukusebenza kwezinto zombane.
9. Uncedo lweFuel
I-ETB ingasetyenziselwa i-co-solvent kunye ne-modifier kwi-fuel entsha ye-boiler, kungekhona nje ukuphucula ukusebenza kakuhle kokutsha, kodwa nokunciphisa ukukhutshwa, njengomthombo wamandla omtsha kwiibhoyili kunye neenjini ezinkulu ze-diesel zaselwandle, kukho iimfuno eziqinileyo zokusingqongileyo kunye neenzuzo zokwahlulwa komgaqo-nkqubo.
