To taub cov kev tshawb fawb ntawm FRP: Vim li cas nws ntau dua tsuas yog yas
Nyob rau hauv cov ntaub ntawv kev lag luam, qhov kev ua kom tsis meej yog saib fiber -}}}} yoog polymer (frp) raws li ib hom yas. Qhov kev tsis to taub yuam kev dhau ntawm cov kev tshawb fawb sib xyaw ua ke uas muab cov ntaub ntawv no lawv lub zog tsis muaj zog thiab kav ntev. Rau cov engineers, kws tsim khoom, nkag lag luam wholesale cov neeg yuav khoom, nkag siab cov lej ntawm Frp yog qhov tseem ceeb rau kev txaus siab ib txwm muaj nyob rau hauv cov kev xav tau ib puag ncig.
Ntawm nws cov tub ntxhais, FRP yog cov khoom siv sib xyaw ua los ntawm ob lub koom haum ua los ntawm ob lub koom haum ua kom muaj zog: {{0} {}} txoj kev tiv thaiv cov kab ke thiab cov tshuaj tiv thaiv Polymer Resin Matrix. Txhua tus ua si ib qho tseem ceeb, muaj lub luag haujlwm tshwj xeeb.
Ua ntej, kev txhawb nqa fibers - hile ib txwm iav fibers- yog tus txha caj qaum ntawm cov khoom siv. Cov fibers muab cov tensile tseem ceeb tshaj plaws lub zog, zoo ib yam li cov kav hlau hauv cov pob zeb sib txuas. Thaum bundled ua ke rau hauv cov khoom xws li fiberglass round pas nrig lossis woven rau hauv mats, lawv yuav tiv taus lub zog loj thiab nruj tsis tas yuav ncab lossis tawg. Qhov ntom ntom thiab kev qhia ntawm cov fibers yog precisely tswj tau thaum tsim kom ua tiav cov yam ntxwv kev ua tau zoo.
Thib ob yog cov txhab nyiaj polymer resin matrix. No redin ua haujlwm ntau lub zog tseem ceeb. Nws ua raws li phau ntawv binder, tuav cov iav fibers nyob rau hauv lawv cov kev qhia ncaj ncees thiab hloov chaw ntxeem tau ntawm lawv. Qhov tseem ceeb, lub resin encapsulates thiab tiv thaiv cov fibersulates thiab tiv thaiv cov fibers los ntawm kev hem thawj sab nraud, suav nrog cov noo noo, tshuaj lom neeg, thiab UV hluav taws xob. Lub plhaub tiv thaiv no yog dab tsi ua rau fp inherently corrosion {}} pov thawj thiab muab nws qhov tshwj xeeb depability. Yog tsis muaj lub resin, cov fibers yuav muaj kev yooj yim thiab tsis muaj txheej txheem txheej txheem.
Cov khawv koob tshwm sim thaum ob feem ntawm cov koom ua ke los ntawm cov txheej txheem pultrusion. Thaum lub sij hawm pultrusion, cov iav fibers tau rub los ntawm da dej ntawm cov kua retin thiab tom qab ntawd coj los ntawm cov hlau root steel tuag. Cov khaub ncaws tuag rau hauv nws daim ntawv kawg-}} Nws yog ib tug yooj yim frp profile, lossis ib qho yooj yim frp pultruded tiaj tus phaj. Sab hauv qhov kub tuag, lub resin cures thiab hardens, xauv cov fibers nyob rau hauv qhov chaw.
Nkag siab txog lub synergy yog qhov tseem ceeb heev. Frp tsis yog yas; Nws yog ib qho kev sib xyaw ua ke zoo nkauj uas muaj cov puv ntoob muab lub zog thiab lub resin muab kev tiv thaiv thiab daim ntawv. Qhov no yog vim li cas nws yog ib qho kev ntseeg siab rau txhua yam los ntawm cov kab hlau teeb mus rau ntev- kav dej xa cov khoom siv uas yooj yim plastics lossis hlau tsis tuaj yeem sib phim.
