Lub tswv yim ntawm High Melting Point Polyamide Kub Melt Adhesive

High-melting-point polyamide kub-kua nplaum yog kub- melting nplaum nrog polyamide resin ua nws cov khoom tseem ceeb. Nws muaj qhov kub thiab txias ntawm 140-150℃thiab feem ntau yog siv hauv cov txheej txheem shoemaking xws li tawv folding, txias nias, thiab molding. Nws txoj kev npaj suav nrog kev siv dimer linoleic acid, sebacic acid, ethylenediamine, thiab hexamethylenediamine ua raw cov ntaub ntawv, thiab ua cov polyamide resin los ntawm high - kub polycondensation cov tshuaj tiv thaiv nyob rau hauv nitrogen tiv thaiv. Cov txheej txheem suav nrog theem cua sov, kev nyuaj siab, thiab ntsuas tus nqi amine.

Qhov muag muag ntawm cov nplaum no tuaj yeem hloov kho los ntawm kev kho cov khoom siv raw, ua rau nws tsim nyog rau kev ua haujlwm hauv qhov kub ntawm 140-200 degree. Txhawm rau txhim kho siab - qhov kub thiab txias, 1% ntawm pyrazole-raws li tiv thaiv- tus neeg sawv cev kev laus (xws li 1-phenyl-3-pyrazole) feem ntau yog ntxiv rau cov kua nplaum, ua kom ruaj khov txawm tias nyob ntawm 260℃.
