Nkag siab txog ABS thiab PC: Lub hauv paus ntawm Niaj hnub nimno Electronic Enclosures
ABS yog terpolymer sib xyaw ntawm acrylonitrile (rau tshuaj tiv thaiv thiab rigidity), butadiene (rau toughness), thiab styrene (rau processability thiab nto tiav). Nws yog lub chaw ua haujlwm ntawm lub ntiaj teb cov khoom siv hluav taws xob, khoom plig rau nws cov dej ntws zoo heev hauv kev txhaj tshuaj molding thiab muaj peev xwm tsim cov geometry nyuaj xws li snap-fits, bosses, thiab nyias phab ntsa yam tsis muaj warping. Cov qib ib txwm siv rau hauv cov thawv yas ua kom muaj kev cuam tshuam zoo thaum cov nqi seem - zoo rau siab - ntim ntau lawm.
Polycarbonate, engineering thermoplastic muab tau los ntawm bisphenol A thiab phosgene, sawv tawm rau nws cov qauv molecular tshwj xeeb uas tsim cov saw hlau tawv, amorphous polymer. Qhov no ua rau PC nws kos npe "tsis tuaj yeem" lub koob npe nrov-xav tias cov iav tsis muaj phom sij lossis tsom iav kev nyab xeeb txhais ua cov phab ntsa hauv hluav taws xob. PC qib rau cov ntaub thaiv feem ntau suav nrog UV stabilizers lossis nplaim hluav taws kom tau raws li qhov xav tau sab nraum zoov lossis kev lag luam specs.
Ob qho khoom siv yog txhaj tshuaj- molded rau hauv ABS hlws ris lub thawv lossis PC rooj plaub, tab sis lawv cov molecular sib txawv ua rau muaj kev sib txawv hauv qhov tiag -lub ntiaj teb ntim khoom siv hluav taws xob.
Lub zog thiab qhov cuam tshuam tsis zoo: Thaum "Tough txaus" tsis txaus
Lub zog hauv cov ntaub thaiv hluav taws xob tsis yog hais txog tus lej tensile nkaus xwb- nws yog hais txog kev muaj sia nyob thaum lub sijhawm xa khoom, rov qhib lub hau hauv lub tshav pob, thiab kev co hauv kev lag luam.
Polycarbonate dominates ntawm no. Nws muab lub zog tensile nyob ib ncig ntawm 10,000 psi (kwv yees li 69 MPa) thiab ua rau Izod cuam tshuam qhov tseem ceeb ntawm 12–16 ft-lb/in-kwv yees li 3-4 npaug siab dua li tus qauv ABS (4,500 psi tensile thiab 3-5 ft-lb/in. Hauv cov ntsiab lus siv tau, rooj plaub PC tuaj yeem nqus tau qhov cuam tshuam loj heev yam tsis muaj kev tawg, ua rau nws zoo tagnrho rau siab -tsheb ciav hlau sab nraum zoov hluav taws xob hauv tsev xws li cov hnub ci sib txuas lossis cov rooj sib tham hauv txoj kev.
