Engineering yas plhaub cov ntaub ntawv: Engineering plastics xa mus rau cov khoom siv feem ntau siv hauv kev tsim khoom thiab kev ua haujlwm. Tam sim no, engineering plastics feem ntau siv los tsim cov thawv ntawv tuaj yeem muab faib ua peb pawg: PC, ABS thiab PC ABS. Cov khoom siv PC muaj cov cua kub zoo thiab muaj kev cuam tshuam zoo, tab sis nws muaj cov nqi tsim khoom siab thiab tsis zoo hnav tsis kam. ABS cov khoom yog ib qho yooj yim rau txheej txheem thiab tus nqi qis, tab sis nws muaj thermal conductivity tsawg thiab hnyav. PC ABS cov khoom sib txuas cov yam ntxwv ntawm ob cov ntaub ntawv no thiab tsim nyog rau feem ntau saib cov casings.
Cov khoom siv hlau muaj ntau yam khoom siv hlau: tab sis feem ntau ntawm cov ntaub ntawv hlau uas tuaj yeem tsim los ntawm cov khoom vaj khoom tsev muaj lub cev zoo heev. Tam sim no, cov ntaub ntawv hlau feem ntau siv hauv cov chaw tsim khoom vaj khoom tsev feem ntau suav nrog austenite 304 thiab txhuas thiab magnesium alloys. Cov khoom siv hlau no muaj cov khoom sib nqus zoo heev, lub zog thiab rigidity, thiab tuaj yeem tsim tau yooj yim rau hauv nyias, qib siab, high-end zaub cov khoom. Yog li ntawd, cov ntaub ntawv hlau yog cov khoom siv dav tshaj plaws hauv kev tsim vaj tsev tsim khoom.
Cov khoom siv iav Piv nrog cov ntaub ntawv hlau thiab yas, cov khoom siv iav muaj qhov zoo ntawm hardness, nruj, cuam tshuam tsis kam thiab zoo nkauj. Tsis tas li ntawd, cov khoom siv iav tsis cuam tshuam nrog kev sib kis thiab txais cov teeb liab wireless, yog li cov ntaub ntawv ua los ntawm cov khoom siv iav muab kev ua tau zoo dua. Vim tias nws tsis yooj yim thiab yooj yim stained nrog cov ntiv tes, daim ntawv thov ntawm cov khoom siv iav tso saib casing raug txwv.
Cov ntaub ntawv sib xyaw thiab lwm yam khoom siv tam sim no hauv kev tsim khoom. Cov hom ntawm cov khoom sib xyaw feem ntau muaj nyob rau hauv daim ntawv ntawm fibers. Cov ntaub ntawv sib xyaw siv los tsim cov khoom vaj khoom tsev feem ntau suav nrog carbon fiber, iav fiber ntau, Kevlar fiber ntau, thiab lwm yam. Lwm cov ntaub ntawv siv hauv cov ntaub ntawv sib txawv ntawm cov ntoo mus rau cov ntaub ntawv ceramic, pob zeb zoo nkauj thiab cov ntaub ntawv kub thiab nyiaj. Cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm tus nqi ntawm cov ntaub ntawv.
