Iimbonakalo
Inokutsha kodwa ayinakutsha, inevumba elikhethekileyo le-alkyl phenol.Inyibilika etywaleni, ester, alkane, aromatics kunye nezinye izinyibilikisi eziphilayo, ezifana ethanol, acetone, butyl acetate, petroli, toluene, ukunyibilika kwisisombululo alkali eyomeleleyo.Ngeempawu eziqhelekileyo zezinto ze-phenolic, ekudibaneni nokukhanya, ubushushu, ukudibana nomoya, umbala wenziwa nzulu ngokuthe ngcembe.
Kwimveliso yezoshishino, i-p-tert-butylphenol isetyenziselwa ukuveliswa kwe-oyile e-soluble phenolic resin, inki yokushicilela, i-flame retardant, njl.Kwintsimi yezinto zokunxibelelana nokutya, i-p-tert-butyl phenol isoloko isetyenziselwa ukuveliswa kwee-polycarbonate resins, kwaye ingasetyenziselwa ukudibanisa izongezo kwizinto zokudibanisa ukutya.
1. Ukhuseleko lwe-PTBP
I-PTBP ayinayo i-genetic kunye ne-carcinogenic toxicity, kunye ne-toxicity yomlomo ebukhali yeegundane ezine-LD50> 2000 mg / kg ye-toxicity ephantsi.Inomrhawuzelo ophakathi kwisikhumba somvundla.Ixabiso le-NOAEL ye-60 mg / kg · bw / imini yabonwa kwezinye iigundane ezinokuphefumula okungaqhelekanga okanye okunzima ukuphefumula kunye nokunciphisa i-albhamuin ye-plasma ngexesha lokuphindaphinda komlomo we-42.Ngeli xesha, i-PTBP yeye-exogenous phenolic estrogens, kwaye ixabiso le-NOAEL letyhefu yokuzala kweempuku yi-200 mg/kg·bw/ngosuku, ebonisa ubutyhefu obuthile bokuzala.Ngoko ke, i-PTBP inemingcipheko ethile kwaye ifuna ukuhoywa.
2. Ukusetyenziswa kwe-PTBP kwizinto zoqhagamshelwano zokutya
I-PTBP yimathiriyeli ekrwada yekhemikhali engafumanekiyo okanye engekhoyo kwizinto zokunxibelelana nokutya.Ingasetyenziswa njengemveliso yepolymer okanye isongezelelo.
Kwiipolymers, zisetyenziswa ikakhulu njenge-monomer starter kunye ne-ejenti yokutywinwa kokuphela.Ngokomzekelo, kwi-coating based polymers, i-formaldehyde, i-phenol, i-p-tert-butylphenol iipolymers kunye ne-polymers ye-formaldehyde, i-phenol, i-p-tert-butylphenol kunye ne-n-butanol iipolymers ezine-p-tert-butylphenol njenge-monomer kunye ne-starter.Iiplastiki zePoly4,4 '-isopropyl diphenyl carbonate ezitywinwe nge-p-tert-butylphenol kwiipolima zeplastiki.
Njengesongezo, ingasetyenziselwa ukunciphisa umxholo we-end-hydroxyl kwiingubo kunye nokuphucula ukuzinza kweemveliso.Kwiplastiki inokusetyenziswa njenge-antioxidant, efana ne-PS yeplastiki yezinto zoqhagamshelwano zokutya kunye neemveliso, ukwenzela ukuthintela imveliso kwimveliso okanye ukusetyenziswa kwe-oxidation ye-thermal, i-photooxidation reaction speed speed, ukulibaziseka ukuchithwa, inkqubo yokuguga etyheli, kunye nokwandisa inkonzo. ubomi bemveliso.
I-P-tert-butylphenol inezixhobo zokulwa ne-antioxidant kwaye ingasetyenziselwa njenge-stabilizer yerabha, isepha, i-hydrocarbons e-chlorinated kunye nemicu yokugaya.Ukufunxa i-Uv, i-pesticide, irabha, ipeyinti kunye nenye iarhente yokuchasa ukuqhekeka.Ngokomzekelo, isetyenziselwa i-polycarbon resin, i-tert-butyl phenolic resin, i-epoxy resin, i-polyvinyl chloride, i-styrene stabilizer.Ukongeza, kukwayinto ekrwada yokugxotha izinambuzane zamayeza, i-pesticide kunye ne-acaricide, ivumba elimnandi kunye nearhente yokukhusela izityalo.Isenokusetyenziswa njengesithambisi, isinyibilikisi, isongezelelo sedayi kunye nepeyinti, i-antioxidant ye-oyile yokuthambisa, i-oyile yokucoca i-oyile kunye ne-additive of fuel fuel.
Ezinye izicelo:
(1) Kwi-oyile e-soluble phenolic resin, imveliso kunye ne-formaldehyde condensation inokufumaneka kwiinjongo ezahlukeneyo.Kwi-adhesive chloroprene exutywe nge-10-15% yemveliso, ukufumana intlaka enyibilikayo, olu hlobo lokuncamathelisa lusetyenziswa ikakhulu kuthutho, ulwakhiwo, i-civil, ukwenza izihlangu, njl njl. Kwi-inki yokushicilela, ingasetyenziselwa ukuguqulwa kwe-rosin, i-offset. ushicilelo, ifotogravure ephuculweyo njalo njalo.Kwi-insulation varnish, ingasetyenziselwa kwi-coil dip varnish kunye ne-laminate varnish.
(2) Ukuvelisa i-polycarbonate, njenge-phosgene polycarbonate reaction ukupheliswa kwe-agent, ukongeza inani le-Chemicalbook ye-1-3% ye-resin.
(3) Isetyenziselwa i-epoxy resin, i-xylene resin modification;Njenge-polyvinyl chloride stabilizer, i-surfactant, i-UV absorber.
(4) Ngeempawu ze-antioxidant, zingasetyenziswa njenge-rubber, isepha, i-hydrocarbons e-chlorinated kunye ne-nitrocelluloose stabilizer.Ikwayimathiriyeli ekrwada yesithinteli sezinambuzane (iyeza), i-acaricide acaride (isibulali-zinambuzane) kunye nearhente yokukhusela izityalo, ivumba elimnandi, i-synthetic resin, kwaye ingasetyenziswa njengesithambisi, isinyibilikisi, idayi kunye nesihlomelo sepeyinti.Isenokusetyenziswa njengesithako se-demulsifier kwintsimi yeoli kunye nesongezo se-oyile yesithuthi.
