Kev siv ABS yas hauv cov khoom ntim khoom kom zoo nkauj
ABS yas yog ib qho ntawm cov ntaub ntawv tseem ceeb siv rau kev tsim cov khoom ntim khoom kom zoo nkauj, paub txog nws lub zog siab, kev ua haujlwm yooj yim, thiab cov khoom zoo nkauj zoo nkauj. Hauv kev ntim tshuaj pleev ib ce, ABS (Acrylonitrile-Butadiene-Styrene copolymer) yog siv dav rau cov khoom siv xws li lub kaus mom sab nrauv thiab cov thawv ntim vim nws qhov ua tau zoo - sib npaug. Hauv qab no, peb saib tob dua ntawm daim ntawv thov ntawm ABS hauv cov khoom ntim khoom kom zoo nkauj.
Ib
ABS yog dab tsi?
Yooj yim muab, ABS yog cov khoom siv thermoplastic polymer tsim los ntawm copolymerization ntawm peb lub monomers: acrylonitrile (A), butadiene (B), thiab styrene (S). Peb lub monomers no muab ABS nws cov khoom sib npaug thiab ua tiav:
Acrylonitrile (A):Muab tshuaj tiv thaiv thiab kub tsis kam.
Butadiene (B):Muab kev cuam tshuam thiab toughness.
Styrene (S):Muab processability thiab nto gloss.
ABS yog ib qho opaque, tawm -dawb granule uas tuaj yeem ua tiav los ntawm kev txhaj tshuaj molding, extrusion, thiab lwm txoj hauv kev, tso cai rau nws los ua ntau yam ntaub ntawv nyuaj.

Cov yam ntxwv tseem ceeb thiab qhov zoo
Lub cev muaj zog:Qhov ceev yog kwv yees li 1.03-1.07 g / cm³, ua kom cov khoom hnyav. Pwm shrinkage feem ntau yog nruab nrab ntawm 0.4% thiab 0.9%, kom ntseeg tau qhov zoo ntawm qhov ntev.
Mechanical Properties:ABS muaj lub zog zoo heev thiab kev cuam tshuam, muab kev tiv thaiv zoo rau cov khoom tiv thaiv kev puas tsuaj los ntawm kev poob lossis cuam tshuam thaum thauj thiab siv.
Thermal Properties:Standard ABS muaj qhov kub thiab txias deflection ntawm li 93-105℃thiab tsis haum rau siab - kub kom tsis muaj menyuam.
Hluav taws xob cov khoom:ABS muaj hluav taws xob rwb thaiv tsev zoo, nrog rau kev ua haujlwm loj heev tsis cuam tshuam los ntawm cov av noo thiab kub hloov pauv.
Zoo Tshuaj Resistance thiab Stability:ABS tiv taus acids, alkalis, thiab ntau yam tshuaj. Nws qhov kev ua tau zoo tsis cuam tshuam los ntawm kev hloov pauv ntawm cov av noo thiab qhov kub thiab txias, ua kom ruaj khov rau lub sijhawm ntev -.
Kev ua tau zoo heev thiab qhov chaw ua tiav cov khoom:
Yooj yim rau pwm:Raws li cov thermoplastic ua tau yooj yim, ABS tuaj yeem tsim cov khoom sib txawv, siab -cov khoom muaj tseeb.
Muaj zog kho kom zoo nkauj muaj peev xwm:Cov txheej txheem ABS yog du thiab zoo tagnrho rau tom qab dyeing, painting, thiab electroplating. Muaj ntau lub kaus mom kom zoo nkauj uas yuav tsum tau ua kom zoo nkauj los yog siab -gloss zoo li yog tsim los ntawm ABS.

Cov ntawv thov raug siv hauv kev ntim khoom kom zoo nkauj
Tsim kom muaj txiaj ntsig zoo:
ABS muaj lub ntsej muag zoo nkauj thiab yooj yim ua tiav los ntawm electroplating, pleev xim, tshuaj ntsuam luam ntawv, kub stamping, thiab lwm yam. Ntau lub kaus mom naj hoom thiab cov ntaub ntawv compact ua tiav lawv cov xim hlau lossis siab -gloss los ua tsaug rau ABS.
Functional Outer Caps:
Feem ntau ua ke nrog lwm cov ntaub ntawv (xws li, PP rau lub khob sab hauv, PMMA rau lub raj mis) kom sib npaug ntawm kev zoo nkauj thiab kev ua haujlwm. Piv txwv li, lub thawv siab siab -kuaj qab zib tuaj yeem muaj lub hau ABS dawb, lub thawv PMMA pob tshab, thiab PP lub khob sab hauv los txhim kho kev sib khi thiab tiv thaiv kev sib kis.
Xim Cosmetic Ntim:
Dav siv rau eyeshadow palettes, hmoov compacts, thiab lwm yam xim cosmetic ntim, muab ruaj thiab textured tiv thaiv plhaub. Piv txwv li, qee qhov rooj zaum hauv ncoo siv PCR ABS (post-cov neeg siv khoom siv ABS), muab ob qho tib si ib puag ncig cov txiaj ntsig thiab kev ua haujlwm.
Tshwj xeeb -Suab Cheebtsam:
Nws zoo heev moldability enables cim designs. Piv txwv li, ib pob kua mem pleev di ncauj me me tuaj yeem muaj cov npuas sib txawv - zoo li ABS cap, sib txuas ua kom zoo nkauj nrog kev sib khi ua haujlwm.

Kev ceev faj thaum siv ABS yas
Tsis txhob sib cuag ncaj qha nrog cov ntsiab lus:
Tshwj tsis yog cov zaub mov- qib lossis qib ntim cov tshuaj pleev ib ce (xws li Class CC ABS) tau siv meej meej, ABS yuav tsum tsis txhob tiv tauj cov tshuaj nplaum, kua, lossis lwm yam khoom siv tshuaj pleev ib ce. Ua raws li cov cai xws li GB 4806 series yog qhov yuav tsum tau ua.
Tsis txhob tiv tauj nrog cov khoom tshwj xeeb:
Ntim tsim thiab siv yuav tsum zam cov kuab tshuaj organic xws li acetone (cov ntsia thawv polish tshem tawm), ethyl acetate, toluene, thiab siab -cov roj yam tseem ceeb.
Yuav tsum tau ziab ua ntej ua:
ABS yog hygroscopic thiab yuav tsum tau qhuav ntawm 75-90℃rau 2-8 teev ua ntej txhaj tshuaj molding; txwv tsis pub, tej yam tsis xws luag xws li splay marks lossis silver streaks yuav tshwm.
Saib rau Environmental Stress Cracking:
ABS Cheebtsam nrog kev ntxhov siab sab hauv yog qhov ua rau tawg ntxov ntxov thaum raug tshuaj. Kev tsim qauv yuav tsum txo qis kev sib dhos.
Limit Usage Ib puag ncig:
Tsis haum rau ntev - lub sij hawm sab nraum zoov tso saib los yog siab - qhov chaw kub (xws li, nyob rau hauv lub tsheb nyob rau hauv lub tshav ntuj ncaj qha). Khaws cia deb ntawm lub teeb thiab qhov chaw sov.
Prioritize Recyclable Design:
Yog tias lub tuam txhab hais txog kev ruaj ntseg, PCR ABS tuaj yeem siv tau. Ua kom yooj yim ntim cov qauv thiab siv cov khoom siv ib qho uas ua tau los txhim kho kev rov ua dua tshiab.
Tsim thiab Ua Kev Ceeb Toom:
ABS yog tsim rau kev txhaj tshuaj molding tab sis tsis tshuab moulding (vim lub zog yaj tsis txaus). Rau cov khoom uas yuav tsum tau muaj hlau tiav lossis electroplating, ABS yog qhov kev xaiv zoo tshaj plaws, tab sis kev sib raug zoo ntawm cov txheej txheem electroplating thiab substrate yuav tsum tau lees paub.
Cov ntsiab lus
ABS yog cov khoom ntim khoom uas muaj ob qho kev zoo nkauj thiab lub zog, ua rau nws tus nqi - siv tau, siab - tus nqi xaiv rau cov ntim tshuaj pleev ib ce uas "zoo li hwm thiab ua tau zoo."
