styrene rau Acrylonitrile Butadiene Styrene
styrene rau Acrylonitrile Butadiene Styrene,
ABS raw khoom, Styrene rau ABS Resin, styrene siv los tsim ABS, Styrene siv rau cov yas,
ABS muaj cov tshuaj zoo thiab kev ntxhov siab-tawg tsis kam rau inorganic ntsev daws, alkalies, mineral acids (tshwj tsis yog muaj zog oxidizing acids), thiab qee cov ntxhia, zaub, thiab tsiaj roj.ABS yog yooj yim machined los ze rau tolerances, yog tawv, dimensionally ruaj khov, thiab tej zaum kuj yuav thermoformed.Roj av-raws li cov roj, cov kuab tshuaj, thiab cov xim yuav tsum tsis txhob siv, vim lawv yuav ua rau cov khoom craze.ABS kuj yog ib qho ntawm ob peb cov ntaub ntawv uas tsis yog-hlau uas tuaj yeem ua tau yooj yim electroplated (tom qab electroless plating nto tau thov siv cov txheej txheem xaiv etching).
ABS (Acrylonitrile-Butadiene-Styrene) yog ib qho copolymer uas muaj ob lub copolymer thiab yog ib qho ntawm cov khoom siv polymer feem ntau.Styrene thiab Acrylonitrile tsim cov kab hluav taws xob copolymer (SAN) uas ua haujlwm raws li matrix.Butadiene thiab Styrene kuj tsim cov kab copolymer (BS roj hmab) uas ua raws li cov khoom siv muab tub lim.Kev sib xyaw ua ke ntawm ob lub copolymer muab ABS ua ke zoo heev ntawm lub zog, rigidity, thiab toughness.
