ABS sawv cev rau Acrylonitrile Butadiene Styrene. ABS yog qhov cuam tshuam-resistant engineering thermoplastic& amorphous polymer. ABS yog tsim los ntawm peb lub monomers: acrylonitrile, butadiene thiab styrene:
Acrylonitrile: Nws yog ib qho hluavtaws monomer tsim tawm los ntawm propylene thiab ammonia. Qhov feem ua rau ua rau ABS tshuaj ua haujlwm& tshav kub ruaj khov
Butadiene: Nws tsim tawm raws li kev tsim cov khoom ua haujlwm ntawm ethylene los ntawm cov kab nrib pleb. Qhov feem ua haujlwm tau muab qhov hnyav& cuam tshuam lub zog rau ABS polymer
Styrene: Nws yog tsim los ntawm lub cev qhuav dej ntawm ethyl benzene. Nws muab rigidity& cov txheej txheem rau ABS yas.
Yuav tsim li cas ABS?
ABS yog tsim los ntawm emulsion lossis nruam cov txheej txheem. Tus qauv tshuaj lom neeg ntawm Acrylonitrile Butadiene Styrene yog (C8H8 · C4H6 · C3H3N) n. Cov khoom siv ntuj yog xim opaque kaus ntxhw xim thiab yooj yim xim nrog cov xim muaj hlau lossis xim.
ABS yog& muaj zog; ruaj, tawv tiv taus tshuaj tab sis tau yooj yim tawm tsam los ntawm cov kuab tshuaj ncov qaumteb qabteb. Nws muaj cov yam ntxwv zoo dua thiab ua kom kub dua me ntsis cuam tshuam kub dua HIPS.
Acrylonitrile Butadiene Styrene muaj qhov ua qhov rai dav thiab tuaj yeem ua tiav ntawm feem ntau ntawm cov tshuab txheem. Nws tuaj yeem raug txhaj tshuaj-moulded, tshuab-pwm los yog tawg. Nws muaj qhov kub tsawg melting ua rau nws tshwj xeeb rau kev ua los ntawm 3D luam ntawv ntawm lub tshuab FDM.
ABS poob ntawm cov resins txheem (PVC, polyethylene, polystyrene, thiab lwm yam) thiab resins engineering (acrylic, nylon acetal…) thiab feem ntau ua tau raws li cov khoom ntiag tug xav tau ntawm tus nqi tsim nyog tus nqi.
Cov ntaub ntawv yas no muaj pub dawb rau txhua tus, pub dawb. Koj tuaj yeem lim tawm koj cov kev xaiv los ntawm cov cuab yeej (tshuab, hluav taws xob ...), kev siv, hloov dua siab tshiab thiab ntau ntau qhov ntev.
Cov Khoom Tseem Ceeb ntawm ABS Yas
ABS yog cov khoom siv zoo tshaj plaws ntawm kev xaiv rau ntau yam kev teeb tsa, ua tsaug rau nws cov khoom siv lub cev xws li:
Siab rigidity
Qhov zoo cuam tshuam tsis kam, txawm tias nyob hauv qis kub
Zoo insulating zog
Zoo weldability
Kev ua kom zoo thiab lim tsis kam
High stability seem (Mechanically muaj zog thiab ruaj khov thaum lub sijhawm)
Siab nto ci ci thiab zoo nkauj nto
ABS qhia tau zoo tshaj plaws cov cuab yeej zoo xws li nws yog qhov nyuaj thiab tawv ntawm qhov xwm yeem thiab yog li muab cov txiaj ntsig zoo ua rau muaj zog. Acrylonitrile Butadiene Styrene muaj qhov siab ntawm thaj chaw zoo. Sib nrug los ntawm cov yam ntxwv no, Acrylonitrile Butadiene Styrene ua rau pom cov khoom siv hluav taws xob zoo.
Cov Khoom Siv Tshuaj Txhaum Cai ntawm ABS
Zoo heev tsis kam mus rau diluted acid thiab alkalis
Ntshav tsis kam mus rau aliphatic hydrocarbons
Tsis zoo tiv thaiv rau cov uas muaj ntxhiab hydrocarbons, halogenated Hydrocarbons thiab dej cawv

ABS tau yooj yim hloov ob qho tib si los ntawm kev ntxiv rau thiab ntxiv los ntawm kev sib piv ntawm qhov sib piv ntawm peb tus monomers Acrylonitrile, Butadiene thiab Styrene. Thaum tshav kub kub stabilizers, hydrolysis stabilizers, lubricants, UV stabilizers thiab lwm yam yog siv rau hauv qib tsis txuas thiab tsis ntxiv los txhim kho cov khoom tshwj xeeb.
Li no, qib muaj suav nrog:
Siab thiab nruab nrab cuam tshuam
Siab kub ua hauj, thiab
Electroplatable
Cov qib hluav taws kub retardant tuaj yeem tau txais los ntawm kev suav cov hluav taws kub retardant ntxiv lossis los ntawm kev sib xyaw nrog PVC. Txhawm rau txhawm rau txhav txhav, tiv thaiv kev cuam tshuam thiab dim seem kev ruaj ntseg, ABS tuaj yeem ua kom muaj zog nrog cov roj ntsha, chaw sau, cov zaub mov, thiab lwm yam Nws tuaj yeem ua rau poob ntawm pob tshab, cov khoom muaj zog.
