Waxqabad heer sare ah ASA-GF, FR ee alaabta albaabka

Acrylonitrile styrene acrylate (ASA), oo sidoo kale loo yaqaan acrylic styrene acrylonitrile, waa thermoplastic amorphous ah oo loo sameeyay bedelka acrylonitrile butadiene styrene (ABS), laakiin leh caabbinta cimilada oo hagaagtay, waxaana si weyn loogu isticmaalaa warshadaha baabuurta. Waa caag acrylate ah oo wax laga beddelay styrene acrylonitrile copolymer. Waxaa loo isticmaalaa wax-soo-saarka guud ee daabacaadda 3D, halkaas oo iska caabinteeda UV iyo sifooyinkeeda makaanikada ay ka dhigaan wax aad u fiican oo loo isticmaalo daabacadaha qaabaynta qaabaynta.

ASA dhisme ahaan aad bay ugu shabbahay ABS. Qaybaha wareega ee caag acrylate ah oo waxyar iskutallaabta ah (halkii loo isticmaali lahaa caagga butadiene), oo u shaqaynaya sidii wax ka beddelka saamaynta, ayaa kiimiko ahaan lagu tallaalay silsilado kobolymer ah oo styrene-acrylonitrile ah, waxayna ku dhex jiraan matrix styrene-acrylonitrile. Caag acrylate wuxuu ka duwan yahay caag ku salaysan butadiene iyadoo ay maqan yihiin bonds double, kaas oo siinaya walxaha ilaa toban jeer iska caabinta cimilada iyo iska caabinta shucaaca ultraviolet ee ABS, caabbinta kulaylka muddada-dheer ee sare, iyo caabbinta kiimikaad oo wanaagsan. ASA aad ayey uga adkeysi badan tahay dildilaaca walaaca deegaanka marka loo eego ABS, gaar ahaan aalkolada iyo wax badan oo nadiifinta ah. N-Butyl acrylate caag ah ayaa badanaa la isticmaalaa, laakiin ester-yada kale ayaa sidoo kale lala kulmi karaa, tusaale ahaan ethyl hexyl acrylate. ASA waxay leedahay heer kulka kala-guurka dhalada ka hooseeya ABS, 100 °C vs 105 °C, taasoo siinaya sifooyin heerkul hoose oo ka wanaagsan walxaha.
