(1) Kev npaj cov roj-soluble phenolic resin
1. Active phenolic resin
P-tert-butylphenol thiab formaldehyde tau condensed nyob rau hauv qhov kev txiav txim ntawm kev sib deev catalyst los tsim p-tert-butylphenol formaldehyde resin.Cov khoom siv los npaj neoprene nplaum, roj hmab vulcanizing tus neeg sawv cev, txheej, roj, enamelled hlau thiab lwm yam khoom zoo tshuaj.
2. Inactive ntshiab phenolic resin
Siv cov kua qaub ua catalyst, cov condensation ntawm tert-butylphenol thiab formaldehyde tau siv los tsim cov tshuaj tsis muaj zog phenolic resin.Cov resin tshwj xeeb yog siv rau kev npaj ntawm neoprene nplaum.
3. Siv cov cation txauv resin ua catalyst, cov khoom tsis muaj zog phenolic resin tau npaj, tshwj xeeb yog siv los npaj chloroprene nplaum.Txawm hais tias nquag lossis tsis ua haujlwm, cov phenolic resin tuaj yeem tau txais los ntawm kev ntxiv 10 ~ 15% ntawm cov khoom no rau hauv chloroprene nplaum.Chloroprene nplaum feem ntau yog siv rau hauv kev thauj mus los, kev tsim kho, pej xeem khau, thiab lwm yam. Nws kuj tseem siv tau rau kev npaj rosin hloov kho, offset printing, advanced photogravure, thiab lwm yam, nrog rau kev tsim cov coil dip varnish thiab laminate varnish.
(2) Kev npaj cov txuj lom
1. Tert-butylcyclohexyl acetate
2.4- tert-butyl-1,1 dioxethylcyclohexane yog siv los ua raw khoom rau catalytic dehydrogenation los tsim tert-butylcyclohexanone, thiab tom qab ntawd hydrogenated nrog ethylene glycol ester los ua tert-butylcyclohexanol, thiab tom qab ntawd acetylated los tsim tert-butylcyclohexanone uas nquag hu ua cletexanol, violet ester, nrog woody aroma, tuaj yeem muaj ntxhiab tsw zoo nrog violet ib qho.
Tert-butylphenol cyclohexanone muaj zog camphor saj, siv hauv xab npum, tshuaj ntxuav tes.
(3) Siv ua antioxidant thiab stabilizer
Cov condensates ntawm p-tert-butylphenol thiab barium sulfide, dav siv los ua cov khoom ntxiv rau cov roj thiab cov rog, yog condensed nrog sulfur dichloride los yog sulfur monochloride los tsim dialkylphenol sulfide thiab polyalkylphenol sulfide uas tuaj yeem siv los ua corrosion inhibitors thiab antioxidants.Cov khoom no kuj yog siv los ua roj hmab, xab npum, chlorinated hydrocarbons, nitrocelluloose stabilizer.
(4) Siv los ua cov tshuaj tiv thaiv kev txiav tawm ntawm cov txheej txheem phosgene polycarbonate: qhov sib ntxiv yog 1.0 ~ 3.0% ntawm cov resin
(5) Lwm yam kev siv
Siv rau epoxy resin hloov kho, xylene resin hloov kho, condensation cov khoom yog dav siv nyob rau hauv kev npaj ntawm niaj hnub tshuaj tseem ceeb roj thiab xab npum, detergent tsw.Thiab cov ntaub ntawv raw siv los ua polyvinyl chloride stabilizers.Kev cuam tshuam ntawm tert-butylphenol tuaj yeem siv rau hauv kev tsim cov tshuaj tua kab mob antioxidant, cov nplaim hluav taws kub nyhiab, kev npaj tshuaj tua kab emulsifier, thiab lwm yam.
Daim ntawv thov ntawm p-tert-butyl phenol yog qhov dav heev, thiab ntau cov khoom tuaj yeem tsim los ntawm kev ua haujlwm sib sib zog nqus.Tam sim no, ntau yam khoom siv tau siv rau hauv kev lag luam, qee qhov xav tau kev txhim kho sai thiab siv tau.Tam sim no, ntshiab phenolic resin nrog siab softening point tau tsim nyob rau hauv Suav teb.Cov koom haum tshawb fawb ntsig txog yuav tsum pib tam sim los tsim cov qauv thev naus laus zis tshiab ntawm neoprene adhesives, txhawm rau ua kom tau raws li cov neeg siv khoom xav tau sai li sai tau thiab thim rov qab qhov xwm txheej ntawm cov nplaum nplaum.
