ʻAno kino a me kemika
ʻO ka Ethylene glycol tertiary butyl ether (ETB): He mea kemika kūlohelohe, wai ʻaʻohe waihoʻoluʻu a ʻālohilohi me kahi ʻono mint. Hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik, hiki ke hoʻopau i ka amino, nitro, alkyd, acrylic a me nā resins ʻē aʻe. Ma ka lumi wela (25 ° C), hiki ke hui pū me ka wai, haʻahaʻa ʻawaʻawa, haʻahaʻa haʻahaʻa. Ma muli o kona ʻano hydrophilic kū hoʻokahi a me ka hiki ke hoʻoheheʻe i ka fusion, no laila he ʻano hoʻomohala ākea i ke ʻano o nā uhi pale kaiapuni a me ka ikehu hou.

Hoʻohana:Ethylene glycol tertiary butyl etera, ke ano nui i ka ethylene glycol butyl etera, ma ka like ole, he haʻahaʻa haʻahaʻa, haʻahaʻa toxicity, haʻahaʻa photochemical reactivity, etc., akahai i ka ili irritation, a me ka wai like, latex pena dispersion paʻa maikaʻi like me. ʻO ka hapa nui o nā resins a me nā mea hoʻoheheʻe organik, a me ka hydrophilicity maikaʻi. Hiki ke hoʻohana nui ʻia i nā kula he nui e like me ka uhi ʻana, ka inika, ka mea hoʻomaʻemaʻe, ka mea hoʻomaʻemaʻe fiber, plasticizer, organic synthesis intermediate a me ka pena. ʻO kāna mau hoʻohana nui penei:
1. Amea hoʻoheheʻe queous: ka mea nui no nā ʻōnaehana wai hoʻoheheʻe, wai-dispersible latex pena ʻoihana pena. No ka mea kokoke i ka 9.0 ka waiwai HLB o ETB, ʻo kāna hana i ka dispersing system ke kuleana e like me ka dispersant, emulsifier, rheological agent a me ka cosolvent. He hana maikaʻi ia no ka pena latex, ka uhi ʻana i ka colloidal dispersion a me ka hoʻoheheʻe ʻana i ka uhi resin aqueous i nā uhi wai. , No ka pena loko a me waho i loko o nā hale, kaʻa kaʻa mua, kala tinplate a me nā māla ʻē aʻe.
2.  Pʻaʻole hoʻoheheʻe
2.1Ma ke ʻano he dispersant. ʻO ka hana ʻana i ka pena ʻeleʻele ʻeleʻele ʻeleʻele kūikawā a me ka pena ʻeleʻele ʻeleʻele ʻeleʻele, ʻo ka pena acrylic ka mea maʻamau e koi nui i ka manawa nui i ka wili kalapona kalapona kiʻekiʻe e hoʻokō i kahi ʻano maikaʻi, a me ka hoʻohana ʻana i ka ETB i hoʻomoʻa ʻia i ka kalapona kalapona kiʻekiʻe, hiki ke hoʻemi ʻia ka manawa wili e. ʻoi aku ma mua o ka hapalua, a ma hope o ka hoʻopau ʻana ʻO ke ʻano o ka pena ʻoi aku ka maʻalahi a maʻalahi.
2.2Ma ke ʻano he mea hoʻoheheʻe pae hoʻoneʻe, hoʻomaikaʻi i ka hoʻomaloʻo ʻana i ka wai hoʻoheheʻe wai i ka wikiwiki, ʻoluʻolu, ʻālohilohi, adhesion fastness. Ma muli o kona ʻano tert-butyl, he kiʻekiʻe ke kūpaʻa photochemical a me ka palekana, hiki ke hoʻopau i nā pinholes kiʻi pena, nā mea liʻiliʻi a me nā ʻōpū. ʻO nā uhi wai i hana ʻia me ETB he paʻa ka mālama maikaʻi ʻana, ʻoi aku ma lalo o nā kūlana haʻahaʻa haʻahaʻa i ka hoʻoilo.
2.3E hoʻomaikaʻi i ka nani. ETB hoʻohana 'ia i loko o ka amino pena, nitro pena, e pale aku i ka hana o "alani peel" -like hoailona, ​​pena kiʻiʻoniʻoni hoʻonui 2% i 6%.
3.  Ink dispersantHoʻohana ʻia ʻo ETB ma ke ʻano he ink solvent i hana ʻia, a i ʻole e like me ka dispersant diluted i hoʻohana ʻia i ka paʻi ʻana i nā inika, hiki iā ʻoe ke hoʻomaikaʻi nui i ka rheology inika, hoʻomaikaʻi i ka maikaʻi o ka paʻi kiʻekiʻe a me ka gloss, adhesion.
4.  Fmea lawe iberʻO ka US Alied-Signal Company i ka 76% o ka aila mineral i loaʻa i nā fibers polyethylene me ka ETB extraction, ma hope o ka unuhi ʻana o ka ʻaila mineral fiber ua emi iho ka 0.15%.
5.  ʻO Titanium Dioxide phthalocyanine dyeʻO ka hui Canon Iapana iā Ti (OBu) 4-amino-1,3-isoindoline o ka hoʻonā ETB i hoʻoulu ʻia ma 130 ℃ 3h, loaʻa iā 87% maʻemaʻe titanium Phthalocyanine dye. A ʻo ka crystalline oxytitanium phthalocyanine i hana ʻia me ka porous titanium oxide phthalocyanine a me ETB hiki ke hoʻohana ʻia ma ke ʻano he photosensitizer kiʻi paʻi kiʻi i koʻikoʻi i ke kukui lōʻihi.
6.  Mea hoʻomaʻemaʻe hale kūponoUa mālama ʻia ʻo Asahi Denko me ka propylene oxide a me ka huahana hopena i loaʻa iā KOH ETB loaʻa ka poly propylene oxide mono-t-butyl ether, kahi mea hoʻomaʻemaʻe hale kūpono a maikaʻi.
7.  Pena anti-corrosion  hydrosolNippon Paint Company me diethyl ether, acrylic resin, ETB, butanol, TiO2, cyclohexyl ammonium carbonate, anti-foaming agent no ka hoʻomākaukau ʻana i ka pena ʻino wai sol sprayable.
8.  pale kalapona kiʻiʻoniʻoni o nā mea lekiōme ka ETB e like me ka wai kalapona kiʻiʻoniʻoni kū'ē kū'ē, maʻemaʻe kaʻili, hiki ke hoʻopau i ka pinhole a me ka pūnaewele phenomena maikaʻiʻole a hoʻonui i ka hana o nā mea uila.
9.  Kokua wahie 
Hiki ke hoʻohana ʻia ʻo ETB ma ke ʻano he co-solvent a me ka hoʻololi ʻana i nā wahie boiler hou, ʻaʻole wale e hoʻomaikaʻi i ka pono o ka puhi ʻana, akā e hōʻemi hoʻi i ka hoʻokuʻu ʻana, ma ke ʻano he kumu ikehu hou no nā paila a me nā ʻenekini diesel moana nui, aia nā koi koʻikoʻi kaiapuni a me nā pono hoʻokaʻawale kulekele.
