Cov khoom siv xws li abs-yas yog qhov nrov heev thiab xav tau hauv kev tsim khoom ntawm ntau yam khoom siv hluav taws xob thiab khoom siv. Nyob rau tib lub sijhawm, tsis zoo li cov yas, cov khoom siv no muaj cov ntsuas kev ua tau zoo dua, uas tau piav qhia los ntawm nws qhov kev tiv thaiv kev puas tsuaj thiab kev tiv thaiv ib puag ncig. Vim li cas abs yas thiaj li cuam tshuam, thiab nws qhov zoo yog dab tsi?

Cov khoom no yog cov thermoplastic cuam tshuam resistant resin, uas yog kev tshawb fawb hu ua "acrylonitrile-butadiene-styrene copolymer". Cov khoom no zoo ib yam li cov khoom siv yas zoo tib yam. Nws cov xim feem ntau yog yellowish. Txawm li cas los xij, abs-yas hauv pob tshab granules feem ntau pom nyob rau hauv lub ntiaj teb ua lag luam. Tab sis txawm tias qhov ntxoov ntxoo nws twb tau dyed, txawm li cas los xij, cov khoom no qiv nws tus kheej zoo heev rau xim, txawm tias nws twb muaj qhov ntxoov ntxoo.

ua tsaugKev sib xyaw ntawm butadiene thiab acrylonitrile cov ntaub ntawv nrog styrene abs yas ntawv muaj lub zog siab thiab elasticity. Yog li, nws tuaj yeem smelted mus rau hauv cov duab nyuaj tshaj plaws thiab tseem tsis poob nws qhov kev ua tau zoo. Yog li ntawd, ABS yas yog ib qho ntawm cov khoom siv tshaj plaws hauv kev tsim khoom thiab kev lag luam. Los ntawm txoj kev, nyob rau hauv kev lag luam nws yog pom nyob rau hauv daim ntawv ntawm homogeneous granules. Raws li lawv, cov tuam txhab thiab cov tuam txhab tsim cov khoom sib xyaw ua ke ntawm cov chav kawm tshwj xeeb polymers.

Yim abs yas hu ua dab tsi?

Cov yam ntxwv ntawm cov khoom siv no tsis txawv txav ntawm ib leeg, txawm li cas los xij, txawm li cas los xij, hauv tebchaws Russia nws tau cim ntau lub npe. Cov no yog cov ntawv luv "ABS", "ABS", nrog rau ntau lub npe xws li "Copolymer ntawm acrylonitrile, styrene thiab butadiene" lossis "ABS copolymer".

txiaj ntsig

Abs-yas muaj ntau yam zoo dua lwm hom khoom siv polymer. Ua ntej ntawm tag nrho cov, qhov no yog nws siab tsis kam mus rau alkalis, rog, roj av thiab lwm yam aggressive agents. Thiab yog tias qee hom yas tuaj yeem yaj lossis tsis muaj xim nyob rau hauv lawv lub zog, ces ABS copolymer yuav ruaj khov rau ntev li ntev tau. Tsis tas li ntawd, qhov saum npoo ntawm cov khoom siv no tawm heev du thiab ci. Vim li no, yuav luag txhua lub xov tooj ntawm tes niaj hnub, cov rooj plaub yog ua los ntawm ABS yas. Hauv qhov no, matte polymers thiab cov ntaub ntawv raug ntsib,muaj ib theem ntawm sheen.

Flaws

Ntawm qhov tsis zoo ntawm cov khoom siv no, nws tsim nyog sau tseg tias nws tsis tshua muaj kev tiv thaiv rau ultraviolet tshav ntuj (qee tus qauv ntshai tsam raug benzene, acetone thiab ethyl chloride), uas tuaj yeem ua rau cov xim tsis zoo. Tsis tas li ntawd, tsis zoo li polystyrene, cov yas zoo li no muaj cov khoom siv hluav taws xob tsawg. Txawm li cas los xij, qhov muaj qhov tsis txaus no tsis tiv thaiv nws los ntawm kev ntseeg siab ua tus thawj coj hauv cov npe ntawm cov khoom siv polymeric rau kev tsim cov khoom yas ntau yam.
