sifooyinka jirka iyo kiimikaad
Ethylene glycol tertiary butyl ether (ETB): Walax kiimiko oo dabiici ah, dareere aan midab lahayn oo hufan oo leh dhadhan reex ah. Ku milma inta badan dareerayaasha organic, waxay milmi karaan amino, nitro, alkyd, acrylic iyo resins kale. Heerkulka qolka (25 ° C), waxaa lagu qallajin karaa biyo, sun yar, xanaaq yar. Sababtoo ah dabeecadeeda gaarka ah ee hydrophilic iyo awoodda ay u leedahay in ay kala diraan fiyuuska, sidaas darteed waxay leedahay isbeddel horumarineed oo ballaaran oo ku saabsan dahaarka ilaalinta deegaanka iyo tamar cusub.

Adeegsada:Ethylene glycol tertiary butyl ether, beddelka ugu weyn ee ethylene glycol butyl ether, marka la barbardhigo, ur aad u hooseeya, sunta hoose, falcelinta photochemical hoose, iwm. inta badan resins iyo dareerayaasha organic, iyo hydrophilicity wanaagsan. Waxaa si ballaaran loo isticmaali karaa meelo badan sida daahan, khad, wakiilka nadiifinta, wakiilka qoynta fiber, plasticizer, dhex-abuurka organic iyo ka saarida rinjiga. Isticmaalkeeda ugu weyn waa sida soo socota:
1. Adareere dahaarka queous: ugu horrayn nidaamyada aqueous dareeraha ah, rinjiga warshadaha rinjiga biyaha-latex. Sababtoo ah qiimaha HLB ee ETB wuxuu ku dhow yahay 9.0, shaqadeeda nidaamka firdhinta waxay ka ciyaartaa door kala firdhiso, emulsifier, wakiilka rheological iyo qaboojinta. Waxay leedahay waxqabad wanaagsan oo loogu talagalay rinjiga cinjirka ah, daahan kala firdhisan kolloidal iyo milanka daahan resin aqueous ee daahan biyaha ka dhashay. , Wixii rinji gudaha iyo dibadda ee dhismayaasha, primer baabuurta, tinplate midabka iyo beeraha kale.
2. Pwax dareere ah
2.1Sida kala daadsan. Wax soo saarka ee rinjiga akril madow madow gaar ah oo madow, rinjiga akril sida caadiga ah u baahan tahay waqti badan si ay u pigment sare karbon madow shiidi si loo gaaro ganaax gaar ah, iyo isticmaalka ETB qooyay midabka sare carbon madow, waqtiga shiidi waa la dhimi karaa by in ka badan kala badh, iyo ka dib marka la dhammeeyo Muuqaalka rinjigu waa mid aad u siman oo siman.
2.2Sida wakiilka siman ee xumbo-sameeyaha, hagaaji xawaaraha rinjiga biyaha kala firdhiya, simanaanta, dhalaalka, xajinta xabagta. Sababtoo ah qaab-dhismeedka tert-butyl, waxay leedahay xasillooni iyo badbaado photochemical oo sarreeya, waxay baabi'in kartaa pinholes filimka rinjiga, qaybo yaryar iyo goobooyin. Dahaarka biyaha ka soo baxa ee lagu sameeyay ETB waxay leeyihiin xasillooni kaydineed oo wanaagsan, gaar ahaan marka lagu jiro xaaladaha heerkulka hooseeya ee jiilaalka.
2.3Hagaajinta dhalaalka ETB loo isticmaalo rinjiga amino, rinjiga nitro, si looga hortago soo saarista "diirka orange" - calaamado la mid ah, gloss filimka rinji wuxuu kordhay 2% ilaa 6%.
3. Ink kala firdhiyeyETB loo isticmaalo sida dareere khad loo sameeyo, ama sida firdhiso la qaso oo loo isticmaalo daabacaadda khadadka, waxaad si weyn u wanaajin kartaa rheology-ga khad, wanaajin kartaa tayada daabacaadda xawaaraha sare leh iyo dhalaalka, adhesion.
4. Fwakiilka soo saariddaShirkadda US Alied-Signal ilaa 76% saliidda macdanta oo ay ku jiraan fiilooyinka polyetylen iyo soo saarista ETB, ka dib markii la soo saaray saliidda fiber-ka macdanta ah ayaa hoos u dhacday 0.15%.
5. Titanium Dioxide dheeha phthalocyaninShirkadda Canon ee Japan ee Ti (OBu) 4-amino-1,3-isoindoline ee xalka ETB ayaa lagu kiciyay 130 ℃ 3h, waxay heshay 87% dheeh titanium saafi ah Phthalocyanine. Iyo phthalocyanine-ka crystalline oxytitanium ee ka samaysan titanium oxide phthalocyanine iyo ETB waxa loo isticmaali karaa sawir-qaade sawireed kaas oo aad xasaasi ugu ah iftiinka mawjadaha dheer.
6. Nadiifiyaha guriga oo hufanAsahi Denko oo lagu daweeyay propylene oxide iyo badeecada falcelinta ka kooban KOH ETB waxay helaysaa poly propylene oxide mono-t-butyl ether, kaas oo ah nadiifiyaha guriga ugu fiican oo hufan.
7. Rinjiga ka hortagga daxalka hydrosolShirkadda Rinjiga ee Nippon oo leh diethyl ether, resin acrylic, ETB, butanol, TiO2, cyclohexyl ammonium carbonate, wakiilka ka hortagga xumboynta si loo diyaariyo rinjiga daxalka ee sol biyaha.
8. resistor film kaarboon ee qaybaha raadiyahaoo leh ETB sida dareeraha iska caabinta filimka kaarboonka, dusha siman, waxay baabi'in kartaa qulqulka pinhole iyo ifafaale xun waxayna hagaajin kartaa waxqabadka qaybaha korantada.
9. Kaaliyaha Shidaalka
ETB waxaa loo isticmaali karaa sidii isku-darka iyo wax ka beddelka shidaalka kuleyliyaha cusub, kaliya ma wanaajineyso hufnaanta gubashada, laakiin sidoo kale waxay yareysaa qiiqa, sida isha tamarta cusub ee kuleyliyaha iyo matoorada naaftada badda ee waaweyn, waxaa jira shuruudo adag deegaanka iyo faa'iidooyinka qaybsiga siyaasadda.
