| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S36 – Gqoka izingubo ezifanele zokuzivikela. |
Isingeniso
I-4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) iyinhlanganisela yemvelo. I-white crystalline powder enokuqina okushisayo okuphezulu kanye nokumelana nesimo sezulu.
I-compound ingasetshenziswa ukulungisa izinto ze-polyester ezisebenza kakhulu ezinokumelana ne-oxidation ephezulu kanye nokumelana nokushisa, futhi inezinhlobonhlobo zezicelo. Ingasetshenziswa njengesilungisi ukuthuthukisa izakhiwo ze-polyester, njenge-ductility, amandla, nokumelana nesimo sezulu. Ingasetshenziswa futhi njenge-photosensitizer kanye nesengezo se-polymerization catalysts.
Indlela yokulungisa ye-4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) iyinkimbinkimbi futhi idinga ukutholwa ngokusabela okuzinyathelo eziningi. Indlela evame ukusetshenziswa ukusabela i-phthalic acid ne-methylene trifluoride ngaphansi kwezimo ze-alkaline ukunikeza i-4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid).
Ulwazi lokuphepha: Izindlela zokuphatha ezifanele kanye nezinyathelo zokuphepha kufanele zithathwe ngesikhathi sokulungiswa kanye nokusetshenziswa kwale nhlanganisela. Inobuthi obuthile nokucasuka, futhi kufanele igwenywe ekuhogeleni uthuli nokuhlangana nesikhumba, amehlo, njll. Gqoka amagilavu okuzivikela, imaski, nezibuko ukuze uqinisekise ukungena komoya okuhle phakathi nokusebenza.
