Hauv thaj chaw loj ntawm kev lag luam niaj hnub no, p - tert - amylphenol ci ntsa iab zoo li lub hlaws ci ntsa iab, ci ntsa iab tshwj xeeb.
Hais txog nws cov qauv tshuaj lom neeg, nws muaj cov qauv molecular sib txawv, ua rau nws muaj kev ua haujlwm zoo heev thiab ruaj khov. Hauv qhov tsos, nws muaj xim dawb mus rau daj daj, ua cov briquettes, flakes, lossis hmoov av loj. Hauv qab cov qauv tshwj xeeb no muaj peev xwm loj heev.
Thaum tsim cov phenolic resins, nws yog ib qho khoom siv tseem ceeb uas tsis tuaj yeem tsis tau. Cov p - tert - amylphenol formaldehyde resin tsim los ntawm polycondensation nrog formaldehyde qhia txog kev tiv thaiv cua sov zoo heev, tiv thaiv dej, thiab cov khoom siv kho tshuab. Hauv thaj teb coatings, qhov no ua rau nws txhim kho qhov nyuaj, ci ntsa iab, thiab lo rau ntawm cov coatings, ua rau cov coatings tsis yog tsuas yog zoo nkauj xwb tab sis kuj muaj peev xwm tiv thaiv ntev rau cov khoom coated. Hauv thaj teb nplaum, nws tuaj yeem ua kom muaj zog sib txuas thiab tiv thaiv cua sov, txuas ntau yam khoom siv nruj thiab tiv taus kev sim kub siab.
Hauv kev lag luam roj hmab, nws muaj ob lub luag haujlwm ua antioxidant thiab plasticizer. Ua ib qho antioxidant, nws tiv thaiv kev oxidation thiab kev laus ntawm roj hmab, ua rau lub neej ua haujlwm ntawm cov khoom roj hmab ntev dua. Ua ib qho plasticizer, nws txhim kho cov khoom ua haujlwm, ua rau muaj kev ywj pheej thiab elasticity, ua rau kev ua roj hmab yooj yim dua.
Tom qab ua ke nrog ethylene oxide thiab propylene oxide, nws hloov mus ua ib yam khoom siv surfactant uas muaj kev ua tau zoo heev. Hauv cov tshuaj ntxuav tes, nws txo qhov nro ntawm qhov chaw ntawm dej thiab ua kom cov roj tawm thiab tawg ua tej daim me me. Hauv cov tshuaj pleev ib ce, nws ua haujlwm ua ib yam khoom emulsifier los tswj qhov ruaj khov thiab cov qauv ntawm cov khoom. Hauv kev lag luam tshuaj tua kab, nws pab cov khoom xyaw nquag tawg thiab sib xyaw ua ke, txhim kho cov txiaj ntsig ntawm kev siv.
Nrog nws cov khoom zoo heev, p – tert – amylphenol tau koom ua ke tob rau hauv ntau yam lag luam, txhaj tshuaj muaj zog rau hauv kev txhim kho kev lag luam. Kev xaiv p – tert – amylphenol txhais tau tias xaiv cov kev daws teeb meem kev lag luam zoo dua thiab zoo dua, qhib tshooj tshiab hauv kev tsim khoom lag luam.
