Thupi ndi mankhwala katundu
Ethylene glycol tertiary butyl ether (ETB): Zinthu zakuthupi, zopanda mtundu komanso zowoneka bwino zoyaka zokhala ndi kununkhira kwa timbewu. Zosungunuka mu zosungunulira zambiri za organic, zimatha kusungunula amino, nitro, alkyd, acrylic ndi ma resins ena. Kutentha kwapakati (25 ° C), kumatha kukhala kosakanikirana ndi madzi, kawopsedwe kakang'ono, kukwiya kochepa. Chifukwa cha mawonekedwe ake apadera a hydrophilic komanso kuthekera kosungunula kuphatikizika, kotero ili ndi chitukuko chotakata pankhani ya zokutira zoteteza zachilengedwe ndi mphamvu zatsopano.

Zogwiritsa:Ethylene glycol tertiary butyl ether, njira yayikulu yosinthira ethylene glycol butyl ether, mosiyana, fungo lotsika kwambiri, kawopsedwe kakang'ono, kawopsedwe kakang'ono ka photochemical reactivity, etc., kukwiya kwa khungu, komanso kuyanjana kwamadzi, kukhazikika kwa utoto wa latex. ambiri utomoni ndi zosungunulira organic, ndi hydrophilicity wabwino. Itha kugwiritsidwa ntchito m'magawo ambiri monga zokutira, inki, zoyeretsera, fiber wetting agent, plasticizer, organic synthesis intermediate and paint remover. Ntchito zake zazikulu ndi izi:
1. Aqueous ❖ kuyanika zosungunulira: makamaka zamakina osungunulira amadzimadzi, utoto wopaka utoto wa latex wamadzi. Chifukwa mtengo wa HLB wa ETB uli pafupi ndi 9.0, ntchito yake mu dongosolo lobalalitsa imakhala ngati dispersant, emulsifier, rheological agent ndi cosolvent. Imagwira ntchito bwino pakupaka utoto wa latex, zokutira zobalalika za colloidal ndikusungunula zokutira zamadzimadzi mu zokutira zamadzi. , Kwa utoto wamkati ndi wakunja m'nyumba, zoyambira zamagalimoto, tinplate zamitundu ndi magawo ena.
2.  Ppalibe zosungunulira
2.1Monga wobalalitsa. Kupanga utoto wapadera wakuda ndi wapadera wakuda wa acrylic wakuda, utoto wa acrylic nthawi zambiri umafunikira nthawi yochuluka kuti ukhale ndi pigment wakuda wakuda wakuda kuti ukwaniritse ubwino wina, ndi kugwiritsa ntchito ETB wonyowa kwambiri pigment mpweya wakuda, nthawi yopera imatha kuchepetsedwa ndi kuposa theka, ndipo atatha Kuwoneka kwa utoto kumakhala kosalala komanso kosalala.
2.2Monga kusalaza wothandizira defoamers, kusintha madzi kubalalitsidwa utoto kuyanika liwiro, kusalala, gloss, adhesion fastness. Chifukwa cha mapangidwe ake a tert-butyl, ali ndi kukhazikika kwapamwamba kwa photochemical ndi chitetezo, amatha kuthetsa mapini a filimu ya utoto, tinthu tating'onoting'ono ndi thovu. Zovala zamadzi zopangidwa ndi ETB zimakhala ndi kukhazikika kosungirako bwino, makamaka pansi pa kutentha kochepa m'nyengo yozizira.
2.3Konzani gloss. ETB ntchito amino utoto, nayitrogeni utoto, kuteteza kupanga "lalanje peel" - ngati zolembera, utoto filimu gloss kuchuluka 2% mpaka 6%.
3.  Indi dispersantETB ntchito monga zosungunulira inki zopangidwa, kapena dispersant kuchepetsedwa ntchito inki kusindikiza, mukhoza kwambiri kusintha inki rheology, kusintha khalidwe la mkulu-liwiro kusindikiza ndi gloss, adhesion.
4.  Fiber extraction agentUS Alied-Signal Company mpaka 76% yamafuta amchere okhala ndi ulusi wa polyethylene wokhala ndi ETB m'zigawo, pambuyo pochotsa mafuta amchere adatsika ndi 0.15%.
5.  Titanium Dioxide phthalocyanine utotoKampani yaku Japan Canon kupita ku Ti (OBu) 4-amino-1,3-isoindoline ya ETB yankho idalimbikitsidwa pa 130 ℃ 3h, idalandira utoto wa 87% wa titaniyamu wa Phthalocyanine. Ndipo crystalline oxytitanium phthalocyanine yopangidwa ndi porous titanium oxide phthalocyanine ndi ETB ingagwiritsidwe ntchito ngati chithunzithunzi cha photosensitizer chomwe chimakhudzidwa kwambiri ndi kuwala kwautali wautali.
6.  Wotsuka bwino m'nyumbaAsahi Denko amathandizidwa ndi propylene oxide ndi zomwe zili ndi KOH ETB amapeza poly propylene oxide mono-t-butyl ether, yomwe ndi yabwino komanso yoyeretsa bwino m'nyumba.
7.  Utoto woletsa dzimbiri  hydrosolKampani ya Nippon Paint yokhala ndi diethyl ether, acrylic resin, ETB, butanol, TiO2, cyclohexyl ammonium carbonate, anti-foaming agent kuti akonze utoto wothira madzi amadzimadzi.
8.  mpweya filimu resistor wa zigawo wailesindi ETB monga madzi carbon filimu resistors kukana, yosalala pamwamba, angathe kuthetsa pinhole ndi zoipa zochitika ukonde ndi bwino ntchito ya zigawo zamagetsi.
9.  Mafuta Othandizira 
ETB ingagwiritsidwe ntchito ngati co-solvent ndi modifier mu mafuta otenthetsera atsopano, osati kungowonjezera kuyaka bwino, komanso kuchepetsa mpweya, monga gwero lamphamvu lamagetsi amagetsi ndi injini zazikulu za dizilo, pali zofunikira zowonongeka kwa chilengedwe ndi phindu la magawo.
