Imikhiqizo
CAS No. 7580-85-0 Ethylene Glycol Mono-Tert-Butyl Ether/Etb/Ethylene Glycol Tertiary Butyl Ether
Incazelo Yomkhiqizo
I-2-Butoxyethanol iyi-solvent yamapende nama-surface coatings, kanye nemikhiqizo yokuhlanza noyinki. Imikhiqizo equkethe i-2-butoxyethanol ihlanganisa ukwakhiwa kwe-acrylic resin, i-asphalt release agent, igwebu elicisha umlilo, izivikeli zesikhumba, izisabalali zokuchitheka kukawoyela, izinhlelo zokusebenza zokukhipha amafutha, izisombululo zemidwebo yezithombe, izihlanzi zebhodi elimhlophe nezingilazi, insipho ewuketshezi, izimonyo, izixazululo zokuhlanza ezomile, ama-lacquers, ama-varnish, imithi yokubulala ukhula, opende be-latex, okoqweqwe lwawo, ukunamathisela okuphrintayo, nezikhiphi zokuvanisha, ne-silicone caulk. Imikhiqizo equkethe le nhlanganisela ivame ukutholakala ezindaweni zokwakha, izitolo zokulungisa izimoto, izitolo zokuphrinta, kanye nezinsiza ezikhiqiza imikhiqizo yokubulala amagciwane kanye neyokuhlanza.

Izinyathelo Zokuqaphela Isitoreji
I-2-Butoxyethanol ivame ukukhiqizwa embonini kawoyela ngenxa yezakhiwo zayo ezitholakalayo.
Embonini ye-petroleum, i-2-butoxyethanol iyingxenye yoketshezi oluqhekekayo, iziqinisi zokubhoboza, nezisabalalisi ezishesha uwoyela kukho kokubili ukuqhekeka kwe-hydraulic okususelwe emanzini kanye nowoyela.[ukucaciswa kuyadingeka] Uma uketshezi luphonswa emthonjeni, uketshezi oluqhekekayo luyaba. iphonswe ngaphansi kwengcindezi enkulu, ngakho-ke i-2-butoxyethanol isetshenziselwa ukuzinzisa ngokunciphisa ukungezwani okungaphezulu.Njenge-surfactant, i-2-butoxyethanol idonsa ku-interface yamafutha-amanzi e-fracture.Inhlanganisela iphinde isetshenziselwe ukusiza ukukhululwa kwegesi. ngokuvimbela ukugqwala.Ibuye isetshenziswe njengesinyibilikisi esihlanganisa uwoyela ongahluziwe namanzi ukuze kusetshenziswe eminye imithombo kawoyela.
I-2-Butoxyethanol ivamise ukungena ohlelweni lomzimba womuntu ngokumunca isikhumba, ukuhogela, noma ukusetshenziswa ngomlomo kwekhemikhali.I-ACGIH threshold limit value (TLV) yokuchayeka kwesisebenzi ingu-20 ppm, engaphezulu kakhulu komkhawulo wokuthola iphunga ongu-0.4 ppm. Ukugxila kwegazi noma umchamo we-2-butoxyethanol noma i-metabolite 2-butoxyacetic acid kungalinganiswa kusetshenziswa amasu e-chromatographic. Inkomba ye-biological exposure ye-200 mg 2-butoxyacetic acid nge-g creatinine isungulwe ku-specimen yokuphela komchamo wokushintsha kubasebenzi base-US. I-2-Butoxyethanol kanye nama-metabolites ayo awela emazingeni angabonakali emchameni ngemva kwamahora angaba ngu-30 emadodeni.
Inzuzo
Izinga lomkhiqizo, inani elanele, ukulethwa okuphumelelayo, izinga eliphezulu lesevisi Inenzuzo kune-amine efanayo, i-ethanolamine, ngokuthi ukugxilisa okuphezulu kungase kusetshenziselwe amandla afanayo okugqwala. Lokhu kuvumela abacwengi ukuthi bakhuhle i-hydrogen sulfide ngenani eliphansi le-amine elijikelezayo ngokusetshenziswa kwamandla sekukonke.
