Ethylene glycol tertiary butyl ether (ETB): Chida chachilengedwe, chopanda utoto komanso chowonekera bwino chomwe chimayaka moto chokhala ndi kukoma kwa timbewu ta ...

Ntchito:Ethylene glycol tertiary butyl ether, njira ina yaikulu m'malo mwa ethylene glycol butyl ether, mosiyana, fungo lochepa kwambiri, poizoni wochepa, kusintha kochepa kwa photochemical, ndi zina zotero, kuyabwa pang'ono pakhungu, komanso kugwirizanitsa madzi, kukhazikika kwa utoto wa latex. Imagwirizana bwino ndi ma resin ambiri ndi zosungunulira zachilengedwe, komanso hydrophilicity yabwino. Itha kugwiritsidwa ntchito kwambiri m'magawo ambiri monga zokutira, inki, chotsukira, chonyowetsa ulusi, pulasitiki, organic synthesis intermediate ndi chochotsa utoto. Ntchito zake zazikulu ndi izi:
1. Achosungunulira cha queous: makamaka pamakina amadzi osungunula, utoto wa latex wosungunuka m'madzi. Chifukwa chakuti mtengo wa HLB wa ETB uli pafupi ndi 9.0, ntchito yake mumakina osungunula imagwira ntchito ngati dispersant, emulsifier, rheological agent ndi cosolvent. Ili ndi magwiridwe antchito abwino pa utoto wa latex, colloidal dispersion coating ndi dissolving aqueous resin coating mu zophimba zamadzi. , Pa utoto wamkati ndi wakunja m'nyumba, primer yamagalimoto, tinplate yamitundu ndi madera ena.
2.  Psi solvent
2.1Monga chotulutsira. Kupanga utoto wapadera wakuda ndi wakuda wakuda, utoto wa acrylic nthawi zambiri umafuna nthawi yambiri kuti upukute wakuda wa kaboni kuti ukhale wosalala, ndipo kugwiritsa ntchito ETB yonyowa ndi utoto wakuda wa kaboni, nthawi yopukuta ikhoza kuchepetsedwa ndi theka, ndipo mutamaliza mawonekedwe ake ndi osalala komanso osalala.
2.2Monga choyeretsera utoto, chimathandiza kuti utoto uume mofulumira, ukhale wosalala, wonyezimira, komanso wogwirizana. Chifukwa cha kapangidwe kake ka tert-butyl, imakhala ndi kukhazikika kwa photochemical komanso chitetezo, imatha kuchotsa mabowo a utoto, tinthu tating'onoting'ono ndi thovu. Zophimba zamadzi zopangidwa ndi ETB zimakhala ndi kukhazikika bwino kosungira, makamaka kutentha kochepa m'nyengo yozizira.
2.3Konzani gloss. ETB yomwe imagwiritsidwa ntchito mu utoto wa amino, utoto wa nitro, kuti ipewe kupanga zizindikiro zofanana ndi "peel ya lalanje", gloss ya filimu ya utoto inawonjezeka ndi 2% mpaka 6%.
3.  Ink dispersantETB imagwiritsidwa ntchito ngati chosungunulira inki chopangidwa, kapena ngati chosungunulira chochepetsedwa chomwe chimagwiritsidwa ntchito mu inki zosindikizira, mutha kusintha kwambiri rheology ya inki, kusintha mtundu wa kusindikiza kwachangu komanso kunyezimira, komanso kumamatira.
4.  Fwothandizira kuchotsa iberKampani ya US Alied-Signal inapeza 76% ya mafuta amchere okhala ndi ulusi wa polyethylene ndi ETB, ndipo mafuta a ulusi wa mchere atachotsedwa, adatsika ndi 0.15%.
5.  Utoto wa Titaniyamu Dioxide phthalocyanineKampani ya ku Japan ya Canon ku Ti (OBu) 4-amino-1,3-isoindoline ya yankho la ETB inasakanizidwa pa 130 ℃ kwa maola atatu, ndipo inapeza utoto wa 87% wa titanium Phthalocyanine. Ndipo crystalline oxytitanium phthalocyanine yopangidwa ndi titanium oxide yokhala ndi porous phthalocyanine ndi ETB ingagwiritsidwe ntchito ngati photosensitizer yomwe imakhudzidwa kwambiri ndi kuwala kwa kutalika kwa mafunde.
6.  Kuyeretsa bwino nyumbaAsahi Denko wothiridwa ndi propylene oxide ndi mankhwala omwe ali ndi KOH ETB amapeza poly propylene oxide mono-t-butyl ether, yomwe ndi njira yabwino komanso yothandiza yoyeretsera m'nyumba.
7.  Utoto woletsa dzimbiri  hydrosolKampani ya Nippon Paint yokhala ndi diethyl ether, acrylic resin, ETB, butanol, TiO2, cyclohexyl ammonium carbonate, anti-thoaming agent kuti ikonze utoto wothira madzi wothira.
8.  choletsa filimu ya kaboni cha zigawo za wailesindi ETB ngati kukana kwa filimu ya kaboni yamadzimadzi, pamwamba pake posalala, kumatha kuchotsa dzenje la pinhole ndi zochitika zoyipa ndikuwonjezera magwiridwe antchito a zida zamagetsi.
9.  Chothandizira Mafuta 
ETB ingagwiritsidwe ntchito ngati chosungunulira pamodzi ndi chosinthira mafuta atsopano a boiler, osati kungowonjezera mphamvu yoyaka, komanso kuchepetsa mpweya woipa, monga gwero latsopano la mphamvu za boilers ndi injini zazikulu za dizilo zam'madzi, pali zofunikira zolimba zachilengedwe komanso zabwino za phindu la mfundo.
