Nta ntawm PA Kub Melt Glue
Polyamide kub yaj nplaum, tseem hu ua dimeric acid polyamide kub yaj nplaum, yog ua los ntawm dimeric acid thiab polyamine condensation cov tshuaj tiv thaiv ntawm qhov kub thiab txias, zoo heev tshav kub tsis kam, txias tsis kam, hluav taws xob zog, roj tsis kam, tshuaj tiv thaiv thiab nruab nrab kuj; Tasteless, tsis muaj xim; Ceev ceev; tuaj yeem txuas rau ntau yam hlau thiab tsis yog hlau; Zoo compatibility nrog rau lwm yam resins.
Cov khoom siv tuaj yeem siv rau adhesion ntawm fabrics, tawv, ntoo, yas, hlau, ceramics thiab lwm yam ntaub ntawv, raws li zoo raws li rau adhesion thiab kev tiv thaiv ntawm hluav taws xob Cheebtsam, phau ntawv binding, tsis tshua muaj siab txhaj molding txheej txheem, daim kab xev ntau lawm, thiab lwm yam.
High molecular hnyav polyamide kub yaj nplaum nplaum: zoo fluidity, siab bonding zog, qhuav tu thiab ntxuav tsis kam;
Tsawg molecular hnyav polyamide kub yaj nplaum: zoo zog thiab toughness, feem ntau ntawm cov khoom zoo dua EVA kub yaj nplaum.
Nyob rau hauv ib txwm muaj xwm txheej, qhov muag muag ntawm polyamide kub yaj nplaum tuaj yeem yog li ntawm 100 degree mus rau ntau tshaj 200 degree, tuaj yeem tiv taus qhov kub thiab txias mus txog 40 degree, kub tsis kam mus rau 200 degree, ntawm qhov kub thiab txias, qhov tshwj xeeb lub ntiajteb txawj nqus yog feem ntau 0.97 [1].
Cov xim yooj yim ntawm polyamide kub yaj nplaum nplaum yog amber (daj), tab sis nws tuaj yeem hloov mus rau hauv cov xim dub los ntawm kev ntxiv carbon dub, thiab dawb los ntawm kev ntxiv titanium dioxide, thiab muaj qee qhov tsis tshua muaj tshwm sim uas lwm cov xim hloov mus rau lwm cov xim. Xim-hloov polyamide kub yaj nplaum feem ntau yog siv rau hauv cov ntawv tshwj xeeb xws li cov txheej txheem tsis tshua muaj siab txhaj molding.
Txij li thaum polyamide kub yaj nplaum yog tsim los ntawm cov kua qaub thiab amine polymerization cov tshuaj tiv thaiv, feem ntau muaj cov cim qhia ntawm ob qhov kawg ntawm cov kua qaub thiab tus nqi amine raws li kev siv, thiab cov kua qaub thiab amine polymerization cov tshuaj tiv thaiv feem ntau yog txiav los ntawm ib qho kawg ntawm cov tshuaj tiv thaiv yog nyob ze. mus txog rau qhov kawg. Yog li ntawd, nyob rau hauv cov kua qaub thiab amine tus nqi Performance index, nyob rau hauv ib txwm muaj xwm txheej, tus nqi siab acid yog tus nqi qis amine, thiab tus nqi amine siab yog tus nqi qis. Nyob rau hauv cov ntaub ntawv tsis tshua muaj qhov muaj nuj nqis nyob ze rau ib leeg, qhov sib npaug tau mus txog thiab cov tshuaj tiv thaiv xaus.
