Imikorere myiza ASA-GF, FR kubicuruzwa byo hanze

Acrylonitrile styrene acrylate (ASA), nanone yitwa acrylic styrene acrylonitrile, ni amorphous thermoplastique yatejwe imbere nk'uburyo bwa acrylonitrile butadiene styrene (ABS), ariko hamwe no guhangana n’ikirere, kandi ikoreshwa cyane mu nganda z’imodoka. Ni acrylate rubber-yahinduwe styrene acrylonitrile copolymer. Ikoreshwa muri prototyping muri rusange mu icapiro rya 3D, aho irwanya UV hamwe nubukanishi bituma iba ibikoresho byiza byo gukoresha muma printer ya fonction de fonction.

ASA muburyo busa cyane na ABS. Uduce duto twa spherical du cross cross acrylate reberi (aho kuba reberi ya butadiene), ikora nkimpinduka zingaruka, zashizwe mumiti hamwe na styrene-acrylonitrile iminyururu ya copolymer, hanyuma igashyirwa muri matrise ya styrene-acrylonitrile. Rubber ya acrylate itandukanye na reberi ishingiye kuri butadiene mugihe habuze imigozi ibiri, itanga ibikoresho inshuro zigera ku icumi kurwanya ikirere no kurwanya imirasire ya ultraviolet ya ABS, kurwanya ubushyuhe bwigihe kirekire, no kurwanya imiti myiza. ASA irwanya cyane ihungabana ry’ibidukikije kurusha ABS, cyane cyane kuri alcool hamwe n’ibikoresho byinshi byogusukura. Ubusanzwe N-Butyl acrylate reberi ikoreshwa, ariko izindi esters nazo zishobora guhura nazo, urugero nka Ethyl hexyls acrylate. ASA ifite ubushyuhe bwo munsi yikirahure kurenza ABS, 100 ° C vs 105 ° C, itanga ibintu byiza-ubushyuhe buke kubintu.
