Thermosetting hmoov txheej yog siv ntau dua

Thermosetting hmoov txheej yog siv los ntawm cov txheej txheem tshuaj tsuag electrostatic, rhuab mus rau qhov tsim nyog kub thiab kho tau thiab feem ntau yog tsim los ntawm cov qib siab molecular hnyav hnyav resins thiab crosslinker.Cov qauv ntawm cov hmoov thermosetting muaj cov thawj resins: Epoxy, Polyester, Acrylic.

Cov thawj resins no yog siv nrog sib txawv crosslinkers los tsim ntau yam khoom siv hmoov. Ntau cov kab sib txuas, lossis cov tshuaj kho, yog siv rau hauv cov hmoov txheej, nrog rau amines, anhydrides, melamines, thiab blocked los yog non-blocked isocyanates.Qee cov ntaub ntawv kuj siv ntau tshaj ib qho resin hauv cov qauv hybrid.

Thaum lub thermoset hmoov yog thov thiab raug rau cua sov nws yuav yaj, ntws thiab chemically crosslink los ua ib tug tiav zaj duab xis.Cov tshuaj tiv thaiv nyob rau hauv lub kho lub voj voog tsim ib tug polymer network uas muab zoo heev tiv thaiv txheej txheej. Lub thermoset hmoov uas tau kho thiab sib txuas yuav tsis yaj thiab ntws dua yog tias raug cua sov zaum ob.
