Kev Ua Tau Zoo Tshaj Plaws ASA-GF, FR rau cov khoom siv sab nrauv

Acrylonitrile styrene acrylate (ASA), tseem hu ua acrylic styrene acrylonitrile, yog amorphous thermoplastic tsim los ua lwm txoj hauv kev rau acrylonitrile butadiene styrene (ABS), tab sis nrog kev txhim kho huab cua tsis kam, thiab siv dav hauv kev lag luam tsheb. Nws yog acrylate roj hmab hloov kho styrene acrylonitrile copolymer. Nws yog siv rau kev ua qauv dav dav hauv 3D luam ntawv, qhov twg nws cov UV tsis kam thiab cov khoom siv kho tshuab ua rau nws yog cov khoom siv zoo heev rau kev siv hauv fused deposition modeling printers.

ASA yog structurally heev zoo li ABS. Cov khoom sib txuas ntawm me ntsis hla txuas acrylate roj hmab (es tsis yog roj hmab butadiene), ua haujlwm raws li kev hloov pauv, yog tshuaj grafted nrog styrene-acrylonitrile copolymer chains, thiab embedded nyob rau hauv styrene-acrylonitrile matrix. Cov roj hmab acrylate txawv ntawm butadiene raws li roj hmab los ntawm qhov tsis muaj ob daim ntawv cog lus, uas muab cov ntaub ntawv txog kaum npaug ntawm huab cua tsis kam thiab tiv thaiv ultraviolet hluav taws xob ntawm ABS, siab dua cov cua sov mus ntev, thiab cov tshuaj tiv thaiv zoo dua. ASA yog qhov muaj zog tiv thaiv ib puag ncig kev ntxhov siab ntau dua li ABS, tshwj xeeb tshaj yog rau cov cawv thiab ntau cov tshuaj ntxuav. N-Butyl acrylate roj hmab feem ntau yog siv, tab sis lwm yam esters tuaj yeem ntsib ib yam nkaus, xws li ethyl hexyl acrylate. ASA muaj qhov hloov pauv iav qis dua li ABS, 100 ° C vs 105 ° C, muab cov khoom zoo rau cov khoom siv qis.
