Ukusebenza okugqwesileyo kwe-ASA-GF, FR yeemveliso zomnyango wangaphandle

I-Acrylonitrile styrene acrylate (ASA), ekwabizwa ngokuba yi-acrylic styrene acrylonitrile, i-amorphous thermoplastic ephuhliswe njengenye indlela ye-acrylonitrile butadiene styrene (ABS), kodwa ngokumelana nemozulu ephuculweyo, kwaye isetyenziswa ngokubanzi kwishishini lemoto. Yi-acrylate yerabha eguqulweyo ye-styrene acrylonitrile copolymer. Isetyenziselwa ukuchwetheza ngokubanzi kushicilelo lwe-3D, apho ukuxhathisa kwayo kwe-UV kunye neempawu zoomatshini ziyenza ibe yinto egqwesileyo imathiriyeli yokusetyenziswa kwiiprinta zokumisela umzekelo odityanisiweyo.

I-ASA ifana kakhulu ne-ABS. Amasuntswana angqukuva erabha ye-acrylate eqhagamshelwe kancinane (endaweni yerabha ye-butadiene), esebenza njengenguqu yempembelelo, ifakwe ngokwekhemikhali ngamatyathanga e-copolymer e-styrene-acrylonitrile, kwaye ifakwe kwi-matrix ye-styrene-acrylonitrile. Irabha acrylate yahlukile irabha butadiene esekelwe ngokungabikho bonds kabini, nto leyo enika izinto malunga namaxesha alishumi ukuxhathisa weathering kunye nokumelana ultraviolet radiation of ABS, eliphezulu elide elide ukumelana nobushushu, kunye nokumelana imichiza ngcono. I-ASA ixhathisa kakhulu kuxinzelelo lokusingqongileyo lokuqhekeka kune-ABS, ngakumbi kwii-alkoholi kunye neearhente ezininzi zokucoca. Irabha ye-N-Butyl acrylate idla ngokusetyenziswa, kodwa ezinye ii-esters zinokufunyanwa nazo, umz. i-ethyl hexyls acrylate. I-ASA inobushushu obuphantsi beglasi yokutshintsha kune-ABS, i-100 °C vs 105 °C, ibonelela ngeempawu ezingcono zobushushu obuphantsi kwimathiriyeli.
