Kub-melt edge-banding adhesive yog ib chav kawm ntawm cov nplaum tshwj xeeb uas tsim los rau kev sib txuas cov khoom siv hluav taws xob. Nws yog ib qho eco-tus phooj ywg, hnyav-dawb thermoplastic nplaum. Thaum rhuab mus rau qhov kub thiab txias, qhov kub -kua nplaum hloov los ntawm lub xeev khov mus rau lub xeev molten; ib zaug siv rau saum npoo ntawm cov khoom vaj khoom tsev substrate los yog ntug-banding cov ntaub ntawv, nws txias thiab solidifies, yog li bonding PVC ntug-banding sawb rau lub rooj tsavxwm.
Raws li Patent CN115322730B, daim ntawv pov thawj no muaj feem xyuam rau PUR kub-qhib ntug-banding nplaum, nrog rau nws txoj kev npaj thiab daim ntawv thov. Cov khoom siv raw siv xws li isocyanates, polyether polyols, tackifying resins, thiab lwm yam khoom. Cov nplaum ua rau pom cov khoom zoo tshaj plaws, xws li pwm ua haujlwm zoo, lub zog tev tawm, tiv thaiv thermal cycling, thiab tiv thaiv o thaum muab tso rau hauv dej.
