1. Cov iav fiber yog dab tsi?
Cov iav fibertau siv dav vim lawv cov nqi tsim nyog thiab cov khoom zoo, feem ntau hauv kev lag luam composites. Thaum ntxov li xyoo pua 18th, cov neeg European tau paub tias iav tuaj yeem raug tig mus rau hauv cov xov rau kev xaws. Lub hleb ntawm Fabkis Emperor Napoleon twb muaj cov ntaub dai kom zoo nkauj ua los ntawmfiberglassCov iav fiber muaj ob qho tib si filaments thiab luv luv fibers lossis flocs. Cov iav filaments feem ntau siv rau hauv cov ntaub ntawv sib xyaw, cov khoom siv roj hmab, cov siv conveyor, tarpaulins, thiab lwm yam. Cov luv luv fibers feem ntau yog siv rau hauv cov ntaub tsis-woven, engineering plastics thiab cov ntaub ntawv sib xyaw.
Cov iav fiber lub cev zoo nkauj thiab cov khoom siv kho tshuab, yooj yim ntawm kev tsim khoom, thiab tus nqi qis piv raucov roj carbon fiberua rau nws yog cov khoom siv xaiv rau kev ua haujlwm siab composite daim ntawv thov. Cov iav fibers yog tsim los ntawm oxides ntawm silica. Cov iav fibers muaj cov khoom siv kho tshuab zoo heev xws li tsis tshua muaj brittle, muaj zog siab, tsis tshua muaj zog thiab lub teeb yuag.
Cov polymers uas muaj cov iav fiber ntau ntxiv muaj ntau hom iav fiber sib txawv, xws li cov longitudinal fibers, chopped fibers, woven mats, thiabcov ntaub pua plag txiav, thiab siv los txhim kho cov khoom siv kho tshuab thiab tribological ntawm cov polymer composites. Cov iav fibers tuaj yeem ua tiav qhov sib piv siab thaum pib, tab sis brittleness tuaj yeem ua rau cov fibers tawg thaum lub sijhawm ua.
1. cov yam ntxwv ntawm cov iav fiber
Cov yam ntxwv tseem ceeb ntawm cov iav fiber muaj xws li cov hauv qab no:
Tsis yooj yim rau nqus dej:Cov iav fiber yog cov dej tsis haum thiab tsis haum rau khaub ncaws, vim tias cov hws yuav tsis nqus tau, ua rau tus neeg hnav ntub; vim tias cov khoom tsis cuam tshuam los ntawm dej, nws yuav tsis ntsws.
Kev tsis sib xws:Vim tias daim ntaub tsis muaj zog txaus, nws tsis tshua muaj zog thiab tsis yooj yim rov qab los. Yog li ntawd, nws yuav tsum tau kho qhov chaw kom tiv taus kev ntsws.
Muaj Zog Siab:Fiberglass muaj zog heev, yuav luag zoo li Kevlar. Txawm li cas los xij, thaum cov fibers sib txhuam rau ib leeg, lawv tawg thiab ua rau cov ntaub zoo li shaggy.
Kev rwb thaiv tsev:Hauv daim ntawv luv luv fiber, fiberglass yog ib qho insulator zoo heev.
Kev dai tau:Cov fibers drape zoo, ua rau lawv zoo tagnrho rau cov ntaub thaiv.
Kev Tiv Thaiv Kub:Cov iav fibers muaj kev tiv thaiv kub siab, tuaj yeem tiv taus qhov kub txog li 315 ° C, lawv tsis cuam tshuam los ntawm lub hnub ci, tshuaj dawb, kab mob, pwm, kab lossis alkalis.
Muaj kev phom sij:Cov iav fibers raug cuam tshuam los ntawm hydrofluoric acid thiab kub phosphoric acid. Vim tias cov fiber yog cov khoom ua los ntawm iav, qee cov iav fibers nyoos yuav tsum tau ua tib zoo saib xyuas, xws li cov ntaub ntawv rwb thaiv tsev hauv tsev, vim tias cov fiber kawg tsis yooj yim tawg thiab tuaj yeem tho qhov tawv nqaij, yog li yuav tsum hnav hnab looj tes thaum tuav fiberglass.
3. Cov txheej txheem tsim khoom ntawm cov iav fiber
Cov iav fiberyog ib qho fiber uas tsis yog hlau uas tam sim no siv dav ua cov khoom siv hauv kev lag luam. Feem ntau, cov khoom siv raw ntawm cov iav fiber suav nrog ntau yam minerals ntuj thiab cov tshuaj lom neeg ua los ntawm tib neeg, cov khoom tseem ceeb yog silica xuab zeb, limestone thiab soda tshauv.
Cov xuab zeb silica ua haujlwm ua cov khoom siv ua iav, thaum cov tshauv soda thiab limestone pab txo qhov kub yaj. Qhov coefficient qis ntawm kev nthuav dav thermal ua ke nrog kev ua kom sov tsawg piv rau asbestos thiab cov fibers organic ua rau fiberglass yog cov khoom siv ruaj khov uas tso cua sov sai sai.
Cov iav fiberyog tsim los ntawm kev yaj ncaj qha, uas cuam tshuam nrog cov txheej txheem xws li kev sib xyaw, yaj, tig, txheej, ziab, thiab ntim khoom. Lub pawg yog lub xeev pib ntawm kev tsim iav, uas cov khoom siv tau sib xyaw kom huv si thiab tom qab ntawd cov khoom sib xyaw raug xa mus rau lub cub tawg rau kev yaj ntawm qhov kub siab ntawm 1400 ° C. Qhov kub no txaus los hloov cov xuab zeb thiab lwm yam khoom xyaw rau hauv lub xeev yaj; cov iav yaj ces ntws mus rau hauv lub tshuab ua kom huv si thiab qhov kub poob rau 1370 ° C.
Thaum lub sijhawm tig cov iav fibers, cov iav uas yaj yuav ntws tawm los ntawm lub tes tsho uas muaj qhov me me heev. Lub phaj liner raug cua sov hauv hluav taws xob thiab nws qhov kub thiab txias raug tswj kom tswj tau qhov viscosity tas li. Lub tshuab dej tau siv los txias cov filament thaum nws tawm ntawm lub tes tsho ntawm qhov kub ntawm kwv yees li 1204 ° C.
Cov dej ntws ntawm cov iav uas tau nchuav tawm yog rub mus rau hauv cov filaments nrog cov kab uas hla ntawm 4 μm txog 34 μm. Kev nruj yog muab los ntawm kev siv lub tshuab cua ceev ceev thiab cov iav uas tau nchuav raug rub mus rau hauv cov filaments. Hauv theem kawg, cov tshuaj pleev xim ntawm cov roj nplua nyeem, cov khi thiab cov neeg sawv cev sib txuas yog siv rau cov filaments. Kev siv roj nplua nyeem pab tiv thaiv cov filaments los ntawm kev puas tsuaj thaum lawv raug sau thiab qhwv rau hauv cov pob khoom. Tom qab ntsuas qhov loj me, cov fibers raug ziab hauv qhov cub; cov filaments ces npaj txhij rau kev ua tiav ntxiv rau hauv cov fibers txiav, rovings lossis yarns.
4.daim ntawv thov ntawm cov iav fiber
Fiberglass yog ib yam khoom inorganic uas tsis kub hnyiab thiab khaws cia li 25% ntawm nws lub zog pib ntawm 540 ° C. Feem ntau cov tshuaj muaj me ntsis cuam tshuam rau cov iav fibers. Inorganic fiberglass yuav tsis pwm lossis lwj. Cov iav fibers raug cuam tshuam los ntawm hydrofluoric acid, kub phosphoric acid thiab cov alkaline muaj zog.
Nws yog ib qho khoom siv hluav taws xob zoo heev.Cov ntaub fiberglassmuaj cov khoom xws li kev nqus dej tsawg, lub zog siab, tiv taus cua sov thiab dielectric tsis tu ncua, ua rau lawv zoo tagnrho rau cov laug cam luam tawm thiab cov varnishes rwb thaiv tsev.
Qhov sib piv ntawm lub zog siab rau qhov hnyav ntawm fiberglass ua rau nws yog cov khoom siv zoo heev rau cov ntawv thov uas xav tau lub zog siab thiab qhov hnyav tsawg. Hauv daim ntawv textile, lub zog no tuaj yeem yog unidirectional lossis bidirectional, tso cai rau kev ywj pheej hauv kev tsim qauv thiab tus nqi rau ntau yam kev siv hauv kev lag luam tsheb, kev tsim kho pej xeem, cov khoom siv kis las, aerospace, marine, electronics, Tsev thiab cua zog.
Lawv kuj siv rau hauv kev tsim cov khoom sib xyaw ua ke, cov laug cam luam tawm thiab ntau yam khoom siv tshwj xeeb. Kev tsim cov iav fiber thoob ntiaj teb txhua xyoo yog li 4.5 lab tons, thiab cov neeg tsim khoom tseem ceeb yog Tuam Tshoj (60% ntawm kev ua lag luam), Tebchaws Meskas thiab European Union.
