Features
Inopisa asi isingabatike, ine yakakosha alkyl phenol kunhuwa.Soluble mudoro, ester, alkane, anonhuwirira uye zvimwe organic zvinonyungudutsa, akadai ethanol, acetone, butyl acetate, peturu, toluene, soluble mune yakasimba alkali mhinduro.Nemaitiro akajairika ephenolic zvinhu, kusangana nechiedza, kupisa, kusangana nemhepo, ruvara rwakadzika zvishoma nezvishoma.
Mukugadzirwa kwemaindasitiri, p-tert-butylphenol inonyanya kushandiswa mukugadzirwa kwemafuta soluble phenolic resin, inki yekudhinda, flame retardant, etc. PTBP inoshandiswawo se polyvinyl chloride stabilizer, surfactant, uye UV absorber.Mumunda wezvekudya zvekushandisa, p-tert-butyl phenol inowanzoshandiswa mukugadzirwa kwepolycarbonate resins, uye inogona zvakare kushandiswa mukugadzirisa kwezvinowedzera zvezvikafu zvekusangana nazvo.
1. Kuchengetedzwa kwePTBP
PTBP haina genetic uye carcinogenic toxicity, uye acute oral toxicity yemakonzo ane LD50> 2000 mg/kg ndeye yakaderera chepfu.Iine kushatirwa kuri pakati nepakati paganda retsuro.Nhamba yeNOAEL ye60 mg / kg · bw / zuva yakaonekwa mune mamwe makonzo ane kufema kusina kujairika kana kuoma uye kuderera kweplasma albumin panguva ye42-day oral repeat.Zvichakadaro, PTBP ndeye exogenous phenolic estrogens, uye kukosha kweNOAEL kwehupfu hwekubereka kwemakonzo ndeye 200 mg/kg·bw/zuva, zvichiratidza humwe huturu hwekubereka.Naizvozvo, PTBP ine dzimwe njodzi uye inofanirwa kutarisirwa.
2. Kushandiswa kwePTBP mune zvekudya zvekusangana nezvinhu
PTBP ikemikari raw material isingawanikwe kana kushaikwa mune zvekudya zvekusangana nazvo.Inogona kushandiswa se polymer kugadzira kana kuwedzera.
Mumapolymers, anonyanya kushandiswa semonomer starter uye end-sealing agent.Semuenzaniso, mukuputira mapolymers, formaldehyde, phenol, p-tert-butylphenol mapolymers uye mapolymers e formaldehyde, phenol, p-tert-butylphenol uye n-butanol polymers ane p-tert-butylphenol semonomeri uye starter.Poly4,4 '-isopropyl diphenyl carbonate mapurasitiki akavharwa nep-tert-butylphenol mumapurasitiki polima.
Sekuwedzera, inogona kushandiswa kudzikisa zviri mukati mekupedzisira-hydroxyl mumachira uye kugadzirisa kugadzikana kwezvigadzirwa.Mupurasitiki inogona kushandiswa seantioxidant, senge yePS plastiki chikafu chekubata chikafu uye zvigadzirwa, kuitira kuvharidzira chigadzirwa mukugadzira kana kushandiswa kwekupisa oxidation, photooxidation reaction yekumhanya, kunonoka kuderera, yero kuchembera, uye kurebesa sevhisi. hupenyu hwechigadzirwa.
P-tert-butylphenol ine antioxidant zvinhu uye inogona kushandiswa seyakagadzikana yerabha, sipo, chlorinated hydrocarbons uye digestive fibers.Uv inonyudza, mushonga wezvipembenene, rabha, pendi uye imwe anti cracking agent.Semuenzaniso, inoshandiswa ku polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer.Pamusoro pezvo, ihwowo zvinhu zvakasvibirira zvemishonga inodzinga zvipembenene, mushonga wezvipembenene uye acaricide, kunhuhwirira uye mumiriri wekudzivirira chirimwa.Inogona zvakare kushandiswa seyakapfava, solvent, additive yedhayi nependi, antioxidant yemafuta ekuzora, mafuta demulsifier uye kuwedzera kwemafuta emotokari.
Mamwe maapplication:
(1) Kwemafuta soluble phenolic resin, chigadzirwa uye formaldehyde condensation inogona kuwanikwa kune zvakasiyana siyana.Mune chloroprene adhesive yakasanganiswa 10-15% yechigadzirwa, kuwana soluble resin, rudzi urwu rwekunamatira runonyanya kushandiswa mukufambisa, kuvaka, civil, kugadzira shangu, nezvimwewo. Mukudhinda inki, inogona kushandiswa kugadzirisa rosin, offset. kudhinda, advanced photogravure uye zvichingodaro.Mune iyo insulation varnish, inogona kushandiswa mune coil dip varnish uye laminate varnish.
(2) Yekugadzirwa kwepolycarbonate, se phosgene polycarbonate reaction termination agent, ichiwedzera Chemicalbook huwandu hwe1-3% yeresin.
(3) Inoshandiswa epoxy resin, xylene resin modification;Se polyvinyl chloride stabilizer, surfactant, UV absorber.
(4) Iine antioxidant properties, inogona kushandiswa serabha, sipo, chlorinated hydrocarbons uye nitrocelluloose stabilizer.Iri zvakare raw material yezvipembenene zvinodzinga (mushonga), acaricide acaride (pesticide) uye chirimwa chekudzivirira mumiririri, kunhuhwirira, synthetic resin, uye zvakare inogona kushandiswa seyakapfava, solvent, dhayi uye pendi yekuwedzera.Inogona zvakare kushandiswa sechinhu chinongedzo che demulsifier yemunda wemafuta uye yekuwedzera yemafuta emotokari.
