Izimpawu zengozi Xn - enobungozi Amakhodi ezingozi R20/21/22 - Inobungozi uma ihogela, ithinta isikhumba futhi igwinya. R36/38 - Icasula amehlo nesikhumba. Incazelo yokuphepha S36/37 - Gqoka izingubo zokuzivikela ezifanele kanye namagilavu. S46 - Uma igwinyiwe, shela udokotela ngokushesha futhi ubonise lesi siqukathi noma ilebula. Izinkomba zomuntu ze-UN 1986 WGK Germany 1 RTECS KJ8575000 TSCA Yebo Ikhodi ye-HS 2909 43 00 Ikilasi lengozi 6.1 Iqembu lokupakisha Isahluko III Ubuthi LD50 ngomlomo kumagundane: 1,48 g/kg (Smith) Isingeniso I-Butyl ether ye-ethylene glycol yaziwa nangokuthi i-1,4-butanediol dimethyl ether. Ngezansi kunolwazi mayelana nokuma kwayo, ukusetshenziswa, indlela yokukhiqiza kanye nokuphepha: Ikhwalithi: 1. I-Butyl ether ye-ethylene glycol iwuketshezi olungenambala futhi oluvutha kalula. 2. Inobuthi obuncane kanye nokuncibilika okuhle, futhi iyancibilika emanzini, otshwaleni kanye nezincibilikisi ze-ether. Ukusetshenziswa: I-butyl ether ye-ethylene glycol inokuncibilika okuphezulu kanye nokusabalalisa okuhle, futhi isetshenziswa kabanzi ezimbonini ezahlukene. 1. Njenge-dispersant nesihlukanisi kumapende nemibala. 2. Izincibilikisi ezisetshenziswa ekukhiqizeni amapulasitiki, irabha kanye nemicu. 3. Isetshenziswa njengendawo yokusabela kanye nesithwali se-catalyst. 4. Isetshenziswa njengento yokuhlanza kanye nesihlanzi samafutha embonini ye-elekthronikhi. 5. Isetshenziswa ekwenzeni uyinki, ama-pigment kanye nemibala, njll. Indlela: I-Butyl ether ye-ethylene glycol ingatholakala ngokusabela kwe-transesterification ye-1,4-butanediol ne-methyl tert-butyl ether. Izimo zokusabela zingancishiswa ngama-catalyst ane-asidi (njenge-sulfuric acid) kanye namazinga okushisa aphezulu. Ulwazi lokuphepha: 1. I-Butyl ether ye-ethylene glycol inobuthi obuncane, kodwa isewuketshezi oluvutha kalula, ngakho-ke kufanele kunakwe ukuvikela umlilo nokuqhuma. 2. Gwema ukuthintana ngqo nesikhumba namehlo, ukuze uvimbele ukuhogela noma ukugwinya. 3. Lapho igcinwa futhi isetshenziswa, kufanele igcinwe kude nomlilo kanye nama-oxidizing agents. 4. Kufanele igcinwe esitsheni esivalekile futhi kugwenywe ukuthintana nomoya, ukuze kuvinjelwe ukuhwamuka nokuguga. 5. Ngesikhathi sokusebenza, kufanele kusetshenziswe izinto zokuzivikela ezifanele, njengamagilavu amakhemikhali, izibuko kanye nezingubo zokuzivikela.

 

Ukusetshenziswa
I-2-Butoxyethanol (CAS 111-76-2), eyaziwa kabanzi ngokuthi i-butyl cellosolve noma i-ethylene glycol monobutyl ether (EGBE), iwuketshezi olucwebe olunephunga elithambile, isisindo samangqamuzana singu-118.17 g/mol. Ngenxa yesakhiwo samangqamuzana esiyingqayizivele esihlanganisa izici ze-hydrophilic ne-lipophilic, ibonisa amandla okuncibilikisa amahle kakhulu ezinhlobonhlobo zama-resin, amafutha nemibala. Umsebenzi wayo obalulekile embonini yokupenda iwukuba i-coalescent esebenza kahle kakhulu, eqinisekisa ukwakheka kwefilimu elibushelelezi futhi eqinile lapho kusetshenziswa upende we-latex kanye nezinto zokumboza zezakhiwo. Ezintweni zokuhlanza zasekhaya nezokuhlanza zobungcweti isetshenziswa njengesincibilikisi esinamandla nesihlanza amafutha, ikakhulukazi isusa ngempumelelo ukungcola okunamathelayo kwamafutha ne-oyili ezingaphezulu eziqinile, futhi iyingxenye yezinto zokuhlanza izingilazi. Ngaphezu kwalokho, i-2-butoxyethanol iyisakhiwo samakhemikhali esibalulekile sokwenziwa kwama-plasticizer ne-butyl diglycol acetate, futhi isetshenziswa ezintweni zoketshezi lwamabhuleki, uyinki wokuphrinta kanye nengxenye yezinto zokucubungula insimbi. Inkampani i-Xinchem iqinisekisa ukuhlinzekwa okuzinzile komkhiqizo ngokuhlanzeka okungaphansi kuka-99%, okuqinisekiswa isitifiketi sokuhlaziya, futhi inikeza izimo zokubambisana eziguquguqukayo, kuhlanganise ne-custom chemical synthesis kanye ne-contract manufacturing.
