Cov khoom tseem ceeb ntawm cov tshuaj tua kab mob muaj xws li amine compounds, acid anhydrides, phenolic resins, thiab lwm yam. Cov khoom xyaw no ua lub luag haujlwm sib txuas hauv cov resin, yas, adhesive thiab coating industries, tsim cov tshuaj bonds ntawm polymer molecules los txhim kho cov kev ua tau zoo ntawm cov khoom. . cov
Lub mechanism ntawm kev txiav txim ntawm tus neeg sawv cev curing yog ua rau irreversible hloov nyob rau hauv lub thermosetting resin los tsim muaj zog tshuaj bonds los ntawm cov tshuaj tiv thaiv, xws li condensation, nplhaib kaw, ntxiv los yog catalytic tshua. Ntau hom curing agents muaj kev cuam tshuam loj heev rau cov khoom siv kho tshuab, kub tsis kam, dej tsis kam thiab corrosion kuj ntawm cov khoom kho.
Hauv kev siv tswv yim, cov tshuaj tua kab mob feem ntau yog siv rau hauv cov nplaum, txheej thiab castables kom ntseeg tau tias cov ntaub ntawv no tuaj yeem kho thiab ua tiav cov khoom siv lub cev thiab tshuaj lom neeg. Piv txwv li, pob zeb foob hardener yog cov khoom tsim los ntawm cov tshuaj inorganic, chemically active tshuaj thiab silica compounds. Nws txhim kho lub hardness, hnav tsis kam thiab impermeability ntawm pob zeb los ntawm kev nkag mus thiab reacting nrog cov tshuaj lom neeg hauv pob zeb.
