Khoom yam ntxwv ntawm polyamide kub yaj nplaum

Polyamide kub yaj nplaum, tseem hu ua dimer acid polyamide kub yaj nplaum, yog tsim los ntawm siab -kub condensation cov tshuaj tiv thaiv ntawm dimer acid thiab polyamine. Nws muaj cov khoom siv hluav taws xob zoo heev, tiv taus txias, hluav taws xob, roj tsis kam, tshuaj tiv thaiv, thiab kev tawm tsam; nws tsis muaj ntxhiab thiab tsis muaj xim; nws kho sai sai; nws tuaj yeem khi ntau yam hlau thiab tsis yog-hlau; thiab nws muaj kev sib raug zoo nrog lwm cov resins.

Cov khoom siv tuaj yeem siv rau kev sib txuas cov ntaub, tawv, ntoo, yas, hlau, ceramics, thiab lwm yam ntaub ntawv, nrog rau kev sib txuas thiab tiv thaiv cov khoom siv hluav taws xob, phau ntawv khi, tsis tshua muaj - cov txheej txheem txhaj tshuaj molding, thiab daim kab xev ntau lawm.

High molecular hnyav polyamide kub yaj nplaum nplaum: zoo flowability, siab bonding zog, thiab kuj rau qhuav tu thiab ntxuav; Tsawg molecular hnyav polyamide kub yaj nplaum: zoo zog thiab toughness, nrog rau feem ntau cov khoom superior rau EVA kub yaj nplaum.

Feem ntau, lub softening point ntawm polyamide kub yaj nplaum nyob ib ncig ntawm 100℃mus rau saum toj no 200 degree, nws muaj peev xwm tiv taus kub qis mus rau -40 degree, thiab siab kub mus txog 200 degree. Nyob rau hauv chav tsev kub, nws lub ntiajteb txawj nqus yog feem ntau 0.97.

Cov xim yooj yim ntawm polyamide kub yaj nplaum nplaum yog amber (daj), tab sis feem ntau nws tuaj yeem ua xim dub los ntawm kev ntxiv cov pa roj carbon dub, dawb los ntawm kev ntxiv titanium dioxide, thiab qee qhov tsis tshua muaj tshwm sim, lwm cov xim tuaj yeem hloov pauv mus rau lwm cov xim. Xim- hloov polyamide kub yaj nplaum feem ntau yog siv rau hauv cov ntawv tshwj xeeb xws li qis- kev txhaj tshuaj molding.
