Kugwiritsa ntchito ndi chitukuko cha p-tert-butylphenol

(1) Kukonzekera kwa mafuta osungunuka a phenolic resin
1. Yogwira phenolic utomoni
P-tert-butylphenol ndi formaldehyde anafupikitsidwa pansi pa zochita zolimbikitsa kugonana kuti apange p-tert-butylphenol formaldehyde resin.Zogulitsazo zimagwiritsidwa ntchito popanga zomatira za neoprene, zomatira za rabala, zokutira, mafuta, waya wa enamelled ndi zinthu zina zabwino zama mankhwala.
2. Osagwira koyera phenolic utomoni
Pogwiritsa ntchito asidi monga chothandizira, kutsekemera kwa tert-butylphenol ndi formaldehyde kunagwiritsidwa ntchito kupanga utomoni wosagwira ntchito wa phenolic.Utoto umagwiritsidwa ntchito makamaka pokonza zomatira za neoprene.
3. Pogwiritsa ntchito cation exchange resin monga chothandizira, utomoni wosagwira ntchito wa phenolic unakonzedwa, womwe umagwiritsidwa ntchito mwapadera pokonzekera zomatira za chloroprene.Kaya utomoni wokhazikika kapena wosagwira ntchito, utomoni wosungunuka wa phenolic ukhoza kupezeka powonjezera 10-15% ya mankhwalawa mu zomatira za chloroprene.Chloroprene zomatira makamaka ntchito zoyendera, zomangamanga, nsapato boma, etc. Angagwiritsidwenso ntchito pokonza rosin kusinthidwa, offset kusindikiza, patsogolo photogravure, etc., komanso kupanga koyilo kuviika varnish ndi laminate varnish.
(2) Kukonza zokometsera
1. Tert-butylcyclohexyl acetate
2.4-tert-butyl-1,1 dioxethylcyclohexane amagwiritsidwa ntchito ngati zopangira zopangira dehydrogenation kupanga tert-butylcyclohexanone, ndiyeno hydrogenated ndi ethylene glycol ester kukhala tert-butylcyclohexanol, ndiyeno acetylated kupanga tert-butylcyclohexanone violet ester, yokhala ndi fungo lamtengo wapatali, imatha kununkhira bwino ndi violet.
Tert-butylphenol cyclohexanone imakhala ndi kukoma kwamphamvu kwa camphor, komwe kumagwiritsidwa ntchito mu sopo, kununkhira kotsukira.
(3) Amagwiritsidwa ntchito ngati antioxidant ndi stabilizer
Ma condensates a p-tert-butylphenol ndi barium sulfide, omwe amagwiritsidwa ntchito kwambiri ngati zowonjezera zamafuta ndi mafuta, amapangidwa ndi sulfure dichloride kapena sulfure monochloride kuti apange dialkylphenol sulfide ndi polyalkylphenol sulfide yomwe ingagwiritsidwe ntchito ngati corrosion inhibitors ndi antioxidants.Izi amagwiritsidwanso ntchito ngati mphira, sopo, chlorinated hydrocarbons, nitrocelluloose stabilizer.
(4) Ntchito ngati anachita kuthetsa wothandizila phosgene polycarbonate ndondomeko: Kuwonjezera kuchuluka ndi 1.0 ~ 3.0% ya utomoni
(5) Ntchito zina
Amagwiritsidwa ntchito posintha utomoni wa epoxy, kusinthidwa kwa xylene resin, condensation mankhwala amagwiritsidwa ntchito kwambiri pokonzekera mafuta ofunikira a tsiku ndi tsiku ndi sopo, kununkhira kotsukira.Ndipo zopangira zomwe zimagwiritsidwa ntchito ngati polyvinyl chloride stabilizers.The disubstitution wa tert-butylphenol angagwiritsidwe ntchito kupanga antioxidant, nsalu flame retardant, kukonzekera mankhwala emulsifier, etc.
Kugwiritsa ntchito p-tert-butyl phenol ndikwambiri, ndipo zinthu zambiri zimatha kupangidwa kudzera pakukonza kozama.Pakadali pano, zinthu zingapo zakhala zikugwiritsidwa ntchito m'mafakitale, zina zomwe zikufunika kutukuka ndikuzigwiritsa ntchito.Pakalipano, utomoni weniweni wa phenolic wokhala ndi malo ochepetsetsa kwambiri wapangidwa ku China.Madipatimenti ofunikira ofufuza ayenera kuyamba nthawi yomweyo kupanga njira yatsopano yaukadaulo ya zomatira za neoprene, kuti akwaniritse zosowa za ogwiritsa ntchito posachedwa ndikusintha zomatira zochokera kunja.
