ABS-yas: tus yam ntxwv, zoo thiab tsis zoo

A khoom xws li abs-yas, yog heev nrov thiab nyob hauv kev thov nyob rau hauv zus tau tej cov ntau hluav taws xob thiab khoom siv. Yog li, tsis zoo li cov khoom siv hnab yas muaj ib tug muaj kev kawm siab, vim nws cov high kuj mus txhua yam kev puas tsuaj thiab kev tiv thaiv los ntawm ib puag ncig yam tseem ceeb. Yuav ua li cas yog li ntawd ceev abs-yas, thiab dab tsi yog nws zoo?

feature

Qhov no cov ntaub ntawv uas yog ib tug siab tej yam thermoplastic cob uas yog nyob rau hauv scientific lus hu ua "copolymer, acrylonitrile-butadiene-styrene". Qhov no cov ntaub ntawv uas muaj zog reminiscent ntawm ib tug dog dig yas. Nws yog xim feem ntau yellowish xim. Txawm li cas los, lub ntiaj teb no kev ua lag luam yog feem ntau pom nyob rau hauv hnab yas abs tshab hlaws dai. Tab sis nyob rau hauv txawm ntxoov ntxoo nws twb tsis tau pleev xim rau, nyob rau hauv txhua rooj plaub, cov khoom no yog zoo heev muab coloring ntawm, txawm hais tias koj twb muaj ib tug ntxoov ntxoo.

Los ntawm ib tug ua ke ntawm butadiene thiab acrylonitrile nrog styrene ntaub ntawv abs yas ntawv muaj siab zog thiab elasticity zog. Yog li, nws yuav melted nyob rau hauv lub feem ntau complex cov ntaub ntawv, thiab nws tsis poob nws ua hauj lwm zoo kev ua tau zoo. Yog li ntawd, abs-yas yog ib qho ntawm feem siv nyob rau hauv qhuav thiab kev khwv nyiaj txiag ntawm cov ntaub ntawv. Los ntawm txoj kev, nyob rau hauv kev ua lag luam nws tshwm sim nyob rau hauv daim ntawv ntawm cov niaj hnub granules. Raws li rau lawv, lub tuam txhab thiab lub tuam txhab ua ntau yam ntawm composites, xa mus rau ib chav kawm ntawv tshwj xeeb polymers.

Yuav ua li cas raws nraim yas abs?

Tus yam ntxwv ntawm cov khoom no yog tsis ho txawv los ntawm txhua lwm yam, tab sis, dua li no, nyob rau hauv Russia nws yog cim los ntawm ob peb lub npe. Qhov no abbreviated tsiaj ntawv "ABS", "ABS", thiab ntau yam kev cov npe xws li "acrylonitrile copolymer, styrene-butadiene" los yog kuj "ABS copolymer".

zoo

Abs-yas muaj ntau yam zoo dua lwm hom polymeric cov ntaub ntawv. Tus thawj yog nws cov high kuj mus alkalis, Greases, petrol thiab lwm yam kev txhoj puab heev media. Hos ib txhia hom yas yuav tsuas yaj los yog discolor nyob rau hauv lawv lub hwj, lub ABS copolymer yuav steadfastly tuav ntev li ntev tau. Nyob rau hauv tas li ntawd, tus nto ntawm no cov ntaub ntawv uas mus heev du thiab ci iab. Vim rau qhov no, yuav luag tag nrho cov niaj hnub txawb tes, vaj tse nyob yog ua los ntawm ABS yas. Nyob rau hauv cov ntaub ntawv no, muaj matte polymers thiab cov ntaub ntawv, muaj ib tug tej theem ntawm brightness.

shortcomings

Ntawm cov ntsiab disadvantages ntawm no cov ntaub ntawv uas nws muaj nqis ntsoov teev nws tsawg kuj mus ultraviolet tshav ntuj (ib co qauv ntshai raug benzene, acetone thiab ethyl chloride), uas tej zaum yuav ua rau heev ntawm qhov chaw. Tsis tas li ntawd tsis zoo li polystyrene yas muaj ib tug uas tsis muaj hluav taws xob insulating zog. Txawm li cas los, lub xub ntiag ntawm cov shortcomings tsis tiv thaiv nws los confidently coj ib tug uas txoj hauj lwm nyob rau hauv daim ntawv teev cov polymeric ntaub ntawv rau zus tau tej cov ntau yam yas khoom.
