ABS yas yog dab tsi?
ABS yas yog cov khoom siv dav hauv kev lag luam thiab lub neej niaj hnub, nws lub npe tag nrho yog Acrylonitrile Butadiene Styrene (Acrylonitrile Butadiene Styrene), yog cov thermoplastic nrog kev ua haujlwm zoo heev. Hauv tsab xov xwm no, peb yuav txheeb xyuas cov ntsiab lus, cov khoom, thaj chaw siv thiab qhov sib txawv ntawm ABS yas thiab lwm yam yas los pab cov neeg nyeem kom nkag siab zoo dua "ABS yas yog cov khoom siv dab tsi".
1. ABS yas muaj pes tsawg leeg thiab cov qauv
ABS yas yog tsim los ntawm polymerization ntawm peb monomers - acrylonitrile, butadiene thiab styrene. Txhua feem ua lub luag haujlwm tshwj xeeb hauv ABS yas:

Acrylonitrile: muab cov tshuaj tiv thaiv zoo thiab lub zog, muab ABS yas zoo heev hardness thiab rigidity.
Butadiene: muab ABS yas zoo toughness thiab cuam tshuam tsis kam, tshwj xeeb tshaj yog nyob rau hauv qis kub.
Styrene: txhim khu lub gloss, plasticity thiab processability ntawm cov khoom, tso cai rau ABS yas kom muaj fluidity siab thaum lub sij hawm txhaj tshuaj molding txheej txheem.

Los ntawm copolymerizing peb yam hauv cov piv txwv tshwj xeeb, ABS yas tuaj yeem ua tiav qhov sib npaug ntawm qhov tawv, tawv, kev cuam tshuam thiab kev ua haujlwm, uas yog ib qho laj thawj rau nws daim ntawv thov dav.
2. Cov khoom tseem ceeb ntawm ABS yas
Thaum tham txog dab tsi ABS yas yog tsim los ntawm, nws yog ib qho tseem ceeb kom nkag siab txog nws cov yam ntxwv tseem ceeb, uas tau qhia hauv qab no:

Cov khoom siv kho tshuab zoo heev: ABS yas muaj ob qho tib si rigidity thiab toughness, siab cuam tshuam tsis kam, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias tseem tuaj yeem tswj cov khoom zoo.
Yooj yim ntawm kev ua: Vim nws zoo flowability thiab ruaj khov thermoplasticity, ABS yas yog heev haum rau ntau yam molding txheej txheem, xws li txhaj tshuaj, extrusion thiab tshuab moulding.
Tshuaj tiv thaiv: ABS muaj kev tiv thaiv zoo rau ntau yam acids, alkalis thiab roj, ua rau nws haum rau siv nyob rau hauv ib puag ncig hnyav.
Deg tag: Lub xub ntiag ntawm styrene muab ABS cov ntaub ntawv ib tug du, glossy nto uas yog zoo tagnrho rau cov kev siv uas yuav tsum tau ib tug siab ntawm cosmetic zoo, xws li cov khoom vaj tse thiab cov tsheb.

Cov khoom no ua rau ABS yas cov khoom xaiv rau ntau daim ntawv thov kev lag luam.
3. Kev siv thaj chaw ntawm ABS yas
Vim lawv cov khoom zoo tag nrho, ABS yas yog siv nyob rau hauv ntau yam kev lag luam. Cov hauv qab no yog qee qhov kev thov loj hauv cheeb tsam:

Automotive kev lag luam: ABS yas yog dav siv nyob rau hauv sab hauv thiab sab nrauv ntawm lub tsheb, xws li dashboards, qhov rooj panels, log npog, thiab lwm yam., feem ntau yog vim lawv tej yam kuj, puas thiab siab zog.
Cov khoom siv hluav taws xob thiab hluav taws xob: Hauv cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob, ABS yas yog siv los tsim TV vaj tsev, tub yees sab hauv qhov chaw, hoovers, thiab lwm yam, ua tsaug rau lawv cov moldability zoo heev thiab cov tsos zoo.
Cov khoom ua si thiab khoom siv txhua hnub: Vim tias ABS yas tsis muaj tshuaj lom, ib puag ncig tus phooj ywg thiab muaj kev ua haujlwm zoo, nws feem ntau siv los tsim cov khoom ua si xws li Lego blocks, thiab ntau yam khoom siv txhua hnub.

Cov ntawv thov no qhia txog kev ua tau zoo thiab kev ua tau zoo ntawm ABS yas.
4. Kev sib piv ntawm ABS yas thiab lwm yam yas
Hauv kev nkag siab txog dab tsi ABS yas yog tsim los ntawm, nws yuav pab tau los sib piv nws qhov sib txawv nrog rau lwm cov khoom yas kom nkag siab zoo dua nws qhov tshwj xeeb. Piv nrog rau cov yas xws li PVC, PP, thiab PS, ABS yas muaj qhov zoo ntawm cov khoom siv kho tshuab, kev ua haujlwm, thiab cov tsos zoo. Txawm hais tias ABS yog tus nqi kim, nws cov khoom zoo tshaj plaws feem ntau ua rau qhov tsis zoo no.
Piv txwv li, txawm hais tias PVC muaj cov tshuaj tiv thaiv zoo thiab cov nqi zoo, nws tsis zoo rau ABS ntawm cov khoom siv dag zog thiab kev cuam tshuam, thaum PP, txawm tias lub teeb yuag thiab tshuaj tiv thaiv, tsis tshua muaj kev cuam tshuam thiab muaj qhov ua tiav tsawg dua li ABS.
Xaus
ABS yas yog cov thermoplastic ua haujlwm siab nrog lub peev xwm rau ntau yam kev siv. Los ntawm kev sib txuas ntawm acrylonitrile, butadiene, thiab styrene, nws tsim cov khoom siv nrog kev sib xyaw ntawm hardness, toughness, thiab processability, thiab ntau yam kev siv ABS yas hauv tsheb, khoom siv hluav taws xob thiab hluav taws xob, thiab cov khoom ua si tau pom tias nws qhov tseem ceeb hauv kev lag luam niaj hnub thiab lub neej niaj hnub. Yog li ntawd, thaum nug "dab tsi yog ABS yas ua los ntawm", peb tuaj yeem teb kom meej: nws yog ntau lub hom phiaj engineering yas uas sib xyaw ua ke ntau yam zoo heev.
