Thaum tshav kub kub rhiab heev yog hais txog qhov cuam tshuam ntawm cov xim pleev xim rau cov kev hloov pauv uas tsis xav tau -xws li softening, blistering, discoloration, los yog degradation ntawm cov qauv -thaum raug kub siab.
Ximtsis muaj kev mob siab rau cov cua sov- cov tshuaj tiv thaiv tej zaum yuav raug kev txom nyem los ntawm kev txo adhesion, txo qis gloss retention, thiab cuam tshuam cov neeg kho tshuab kev ncaj ncees nyob rau hauv thermal stress.
Cov ntsiab lus tseem ceeb ua rau xim kub rhiab heev:
Resin Hom:Lub thermal stability ntawm cov xim yog feem ntau dictated los ntawm nws lub hauv paus cob. Polymers xws li vinyls thiab cov qauv acrylics muaj qhov tsis tshua muaj cua sov, thaum silicone thiab epoxy-raws li resins xa cov thermal durability.
Plasticizers:Plasticizers tau ntxiv los txhim kho cov xim hloov tau yooj yim, tab sis lawv muaj feem cuam tshuam rau kev tsiv teb tsaws lossis volatilization thaum raug tshav kub. Cov txheej txheem no ua rau cov yeeb yaj kiab softening thiab tsim cov deg imperfections.
Xim xaiv:Kev ua haujlwm thermal ntawm cov xim kuj cuam tshuam los ntawm kev xaiv xim xim. Organic pigments, tshwj xeeb, yog qhov yooj yim rau cua sov-induced fading thiab discoloration.
Kev kho tsis zoo:Kev kho tsis tiav, tshwj xeeb tshaj yog nyob rau hauv thermosetting xim tshuab, ua rau muaj kev kub ntxhov siab, vim tias qhov tsis sib xws los yog ib feem ntawm cov yeeb yaj kiab crosslinked yog inherently tsawg resilient rau siab kub.
