Tus vaj huam sib luag frp
Khoom Piav Qhia
FRP (tseem hu ua iav fiber ntau ntxiv lawm yas, sau ntawv luv ua los ntawm cov khoom siv hluavtaws thiab cov iav fiber los ntawm cov txheej txheem sib xyaw.
Frp daim ntawv yog lub thickosetting polymer cov khoom nrog cov yam ntxwv hauv qab no:
(1) Lub teeb yuag thiab lub zog siab.
(2) Cov tshuaj corrosion zoo frp yog cov khoom siv zoo heev.
(3) Cov khoom hluav taws xob zoo yog cov khoom siv insulating zoo heev, siv los ua lag luam insulators.
(4) Cov khoom lag luam thermal zoo fermal prop muaj tsawg thermal conductivity.
(5) Kev ua haujlwm zoo
(6) Kev ua tiav zoo heev
Cov Ntawv Thov:
Dav siv nyob rau hauv cov tuam tsev, khov thiab tub yees tsev tub yees, tsev noj mov, chav pw, lub qhov rooj, qhov rooj, qhov rooj, qhov rooj, qhov rooj, qhov rooj, qhov rooj, qhov rooj, qhov rooj, cov chaw pw, thiab lwm yam.
