Cov yam ntxwv ua tau zoo ntawm ABS
Raws li Ib qhov txiaj ntsim ntawm cov yam ntxwv ntawm ABS, nws tsis tsuas yog muaj cov yam ntxwv ntawm A, B thiab S tivthaiv homopolymer feem, tab sis tseem highlights cov nyhuv synergistic ntawm peb yam khoom, ua nws tam sim no Ib qho kuj zoo tagnrho thiab qhia kev ua tiav. , butionene muaj zog, ua kom muaj zog, acrylonitrile ua kom cov tshuaj muaj zog, thiab ua rau kub cev deformation kub, tawv hardness thiab tensile zog.Qhov ABS tsis zoo dua kub cev tiv thaiv cov nyhuv polystyrene.Vicat softening point feem ntau thaum muaj li 95 ℃ (siab kub qis qis tshaj li ntawm 110 ℃), feem ntau nyob rau hauv qhov kub ntawm lub cev kub ntawm 90 ℃ los yog qib siab (siab kub resistant li 100 ℃) .Txoj lub cev muaj roj hmab, ua haujlwm.Ua 40 ℃ - tseem pom zoo toughness.Vim nws cov cua sov thiab txias, kev siv cov dav kub ntau, tau generate tus cwj pwm los ntawm - 40 ℃ ~ 100 ℃ .Yog ncab nce coefficient ntawm ABS me, qhov khoom muaj qhov ruaj ntseg zoo thiab zoo siab tsis zoo. Thaum twg raug rau 7Mpa load, qhov loj tsis hloov loj heev, sai thaum lub kub twb nce.ABS muaj zoo mechanical zog.Tensile lub zog, dabtsi yog khoov zog, feem zog thiab hardness yog tag nrho siab.Qhov neeg ua hauj lwm qhov tseem ceeb yuav txawv heev los ntawm hom rau hom.Qhov lub zog ntawm ABS cantilever nqaj feem ntau yog 100 ~ 400J / m.Tensile zog feem ntau yog 35 ~ 55MPa, dabtsi yog khoov zog yog 55 ~ 85Mpa, rockwell hardness yog R90 ~ 115.ABS tau siv los ua khoom siv vim yog nws cov khoom zoo thiab zoo creep tiv thaiv.ABS muaj peev xwm ntawm resisting dej, cov dej hauv inorganic, alkali thiab ntsev, tab sis nws tsis tiv taus oxidizing acid, glacial acetic acid, ntxhia roj, zaub roj, alcohols, uas yuav muaj kev cuam tshuam zoo rau sab hauv Kev nyuaj siab ntawm lub cheebtsam, thiab kev tivthaiv ntev mus yuav ua rau muaj kev nyuaj siab ntxhov plawv. Qhov no, cov kabmob, cov roj carbon monoxide, estrogens, hydrogarbons thiab cov aromatics yuav ua rau o los yog sib tawg. Ntxiv rau, vim muaj pawg B (butadiene) hauv ABS, qauv muaj ob leeg bonds, tsis zoo huab cua tsis kam, yooj yim tsim generowidation laus thiab thermal oxygen laus.Nyob rau hauv kom zoo rau huab cua tsis kam, antioxidant thiab lub teeb stabilizer tuaj yeem muab ntxiv.ABS muaj txoj kev ua zoo thiab kev ua khoom ua ke.Qhov kev kub ntxhov zauv ntawm 180 ~ 230 ℃ .Cov liquidity polystyrene tsawg dua, thermal stability tsis zoo li polystyrene thiab polyethylene, siab ua ntsuas feem ntau tsis tshaj 250 ℃ .Meter muaj cawv zoo rau cov tsos ntawm ABS molded khoom.Txawm tias dej absorption tus nqi ntawm ABS tsis siab (feem ntau nyob ib ncig ntawm 0.3%), ib qho dej me me yuav ua rau cov ntxhuav ntawm cov xim silks ntawm cov khoom ntws. e, nws txawv ntawm PE, PP thiab PE.Qhov cov ntaub ntawv raw yuav tsum tau qhuav thiab cov dej noo noo yuav tsum tau khaws cia hauv qab 0.6% .ABS muaj qhov qis qis tsawg (feem ntau 0.4-0.6%) thiab lub me deformation tom qab cov khoom. Yog li, nws yog qhov yooj yim rau duab qhov chaw uas muaj qhov sib npaug ntawm qhov siab. Qhov tseem ceeb, ABS yog ib qho yooj yim uas yuav tsum tau xim thiab muaj cov yam ntxwv zoo dua qub, xws li yooj yim qhov kho kom zoo nkauj xws li electroplating, zoo thermal sib sau, thiab lwm yam.
