Acrylonitrile butadiene styrene (ABS) yog qhov cuam tshuam-resistant engineering thermoplastic tsim los ntawm acrylonitrile, butadiene, thiab styrene polymers.Nws muaj zog, ruaj, thiab sib xws nrog ntau cov txheej txheem tsim khoom, suav nrog kev txhaj tshuaj molding, fused-deposition modeling (FDM), thiab txawm CNC machining.
Acrylonitrile butadiene styrene ua li cas?
Feem ntau, acrylonitrile butadiene styrene yog tsim los ntawm emulsion los yog polymerizing styrene thiab acrylonitrile nyob rau hauv lub xub ntiag ntawm polybutadiene.Cov txheej txheem no tsim cov saw ntev ntawm polybutadiene uas crisscrosses nrog luv luv chains ntawm polystyrene-co-acrylonitrile, tsim kom muaj zog bonds.ABS tseem tuaj yeem tsim los ntawm kev siv cov txheej txheem patented hu ua nruam loj polymerization.
ABS yog ib qho kev tsim cov khoom siv feem ntau thiab nws los ntawm ntau hom.Nws tuaj yeem ua rau pellets rau kev txhaj tshuaj molding, filament rau kev tsim khoom ntxiv, thiab extruded rau CNC machining.
