Raws li paub zoo, iav yog ib yam khoom uas paub txog nws "brittness". Txawm li cas los xij, nthuav, ib zaug iav tau rhuab thiab kos rau hauv cov iav fibers uas nyias nyias dua li tib neeg cov plaub hau, nws zoo li tsis nco qab nws " xwm" thiab dhau los ua mos li hluavtaws fibers, nrog rau "mos tsis tau nruj" kev ntxhib los mos. Nws toughness txawm tshaj li ntawm stainless hlau hlau ntawm tib lub thickness!
Yog li, dab tsi yog kev siv fiberglass?
Lub iav hlua twisted los ntawm fiberglass tuaj yeem hu ua "tus huab tais ntawm ropes". Ib txoj hlua iav tuab li ntiv tes tuaj yeem nqa lub tsheb thauj khoom puv! Vim nws tsis kam mus rau seawater corrosion thiab xeb, iav ropes yog haum rau siv raws li lub nkoj cables thiab crane ropes. Txawm hais tias cov hlua hluavtaws fiber ntau muaj zog, lawv tuaj yeem yaj ntawm qhov kub thiab txias, thaum iav hlua tsis ntshai. Yog li ntawd, nws muaj kev nyab xeeb tshwj xeeb rau cov neeg tua hluav taws siv cov iav hlua.
Fiberglass tuaj yeem ua rau ntau hom iav ntaub - iav ntaub - los ntawm lub koom haum. Cov ntaub iav tsis ntshai cov kua qaub lossis alkali, yog li nws yog qhov zoo tagnrho rau siv los ua cov ntaub lim dej hauv cov chaw tsim tshuaj. Nyob rau hauv xyoo tas los no, ntau lub tuam txhab tau txais cov ntaub iav es tsis txhob siv cov ntaub paj rwb thiab ntaub burlap los tsim cov hnab ntim khoom. Hom hnab no tsis yog pwm lossis rotten, noo noo-pov thawj thiab corrosion-resistant, ruaj, nrov heev ntawm cov neeg, thiab tseem tuaj yeem txuag tau ntau ntawm cov paj rwb thiab linen. Cov iav fiber ntau phab ntsa ntaub nrog cov qauv zoo nkauj, siv nrog cov nplaum rau ntawm phab ntsa, yog qhov zoo nkauj thiab muaj kuab heev, tshem tawm qhov xav tau kev pleev xim thiab tu. Yog hais tias nws tau qias neeg, tsuas yog so nrog ib daim ntaub, thiab phab ntsa yuav huv dua tam sim ntawd.
Cov iav fiber ntau yog ob qho tib si insulating thiab kub-resistant, ua rau nws zoo heev rwb thaiv tsev cov ntaub ntawv. Tam sim no, feem ntau lub tshuab hluav taws xob thiab hluav taws xob hauv Suav teb tau siv cov iav fiber ntau los ua cov khoom siv rwb thaiv tsev. Lub 6000 kW chav turbine generator, nrog ntau tshaj 1800 rwb thaiv tsev cov khoom ua los ntawm fiberglass! Vim yog siv cov iav fiber ntau ua cov khoom siv rwb thaiv tsev, kev ua haujlwm ntawm lub cev muaj zog tau raug txhim kho, qhov ntim ntawm lub cev muaj zog tau txo, thiab tus nqi ntawm lub cev muaj zog tau qis dua. Nws yog qhov tseeb yeej-yeej qhov xwm txheej.
Lwm qhov tseem ceeb ntawm kev siv fiberglass yog kev sib koom tes nrog cov ntaub ntawv xws li resins los tsim ntau cov ntaub ntawv fiberglass. Piv txwv li, los ntawm immersing khaubncaws sab nraud povtseg ntawm iav ntaub nyob rau hauv kub yaj resin cov ntaub ntawv thiab nias nws mus rau hauv cov duab, nws ua tus nto moo "fiberglass". Fiberglass tseem tawv dua li cov hlau, tsis xeb los yog corrosion resistant, thiab hnyav ib feem peb ntawm tib lub ntim li hlau. Yog li ntawd, siv nws los tsim lub plhaub ntawm lub nkoj, tsheb, tsheb ciav hlau, thiab tshuab qhov chaw tuaj yeem tsis tsuas yog txuag tau ntau ntawm cov hlau, tab sis kuj tseem ua kom muaj peev xwm ua tau zoo los ntawm kev txo qhov hnyav ntawm lub tsheb thiab nkoj lawv tus kheej. Txij li nws yuav tsis xeb, nws tuaj yeem txuag tau ntau tus nqi txij nkawm.
Yog hais tias lub iav yog yaj thiab tshuab mus rau hauv nyias thiab luv fibers siv high-speed airflow los yog nplaim taws, nws yuav ua iav ntaub plaub. Muaj ib hom dej noo-pov thawj ultra-nplua iav ntaub plaub, nrog ntau tshaj 200 strands ua ke thiab tsuas yog nyias li ib cov plaub hau. Cov iav ntaub plaub muaj qhov muaj zog tiv thaiv zoo heev. 3cm tuab iav ntaub plaub tuaj yeem muab rwb thaiv tsev sib npaug rau 1-meter-thick cib ntsa! Lub suab nqus cov nyhuv ntawm iav ntaub plaub kuj zoo heev. Yog li ntawd, nws yog siv los ua cov khoom siv rau rwb thaiv tsev, suab rwb thaiv tsev, thermal rwb thaiv tsev, poob siab tsis kam, thiab pom nyob rau hauv ntau cov sectors.
Fiber endoscope uas tau tshwm sim nyob rau hauv xyoo tas los no tso cai rau cov kws kho mob saib ncaj qha rau hauv lub cev xws li lub plab, duodenum, thiab lub plawv. Qhov no kuj yog kev koom tes ntawm fiberglass. Thaum lub teeb nkag mus rau hauv cov iav fiber ntau los ntawm ib qho kawg ntawm cov fiber ntau, nws yuav ua rau pom tag nrho rau sab hauv ntawm lub diagonally opposite sab thaum nws mus txog rau sab hauv ntawm cov fiber ntau. Qhov kev rov qab xav dua no ua rau lub teeb txav mus rau hauv txoj kev winding zoo li cuaj nkhaus choj, thaum kawg mus txog qhov kawg ntawm ib kawg. Tau kawg, hauv kev siv tiag tiag, kaum tawm txhiab tus iav fibers tau khi ua ke los tsim ib lub iav fiber ntau. Txhawm rau tiv thaiv lub teeb los ntawm kev xau ntawm cov pas nrig fiber ntau, ib txheej ntawm cov khoom siv qis refractive index tseem qhwv ib ncig ntawm cov pas nrig fiber ntau. Raws li ntev raws li cov iav fibers ntawm ob qhov kawg yog densely teem nyob rau hauv tib txoj kev txiav txim, cov duab kho qhov muag yuav kis tau los ntawm ib kawg mus rau lwm yam yam tsis muaj distortion. Lub teeb pom kev zoo txais cov khoom siv hluav taws xob sab nraud, thiab cov pas nrig fiber ntau yog nruab nrog lub lens ntawm sab xub ntiag. Tus tshiab "tag nrho saib" fiber ntau optic daim iav muaj qhov pom qhov rai uas tuaj yeem saib rau pem hauv ntej lossis tig mus rau sab saib. Nws tseem tuaj yeem nruab nrog lub koob yees duab me me lossis xim TV rau kev qhia lossis kev sib tham ntau tus neeg.
Tsis tas li ntawd, kev siv cov khoom siv kho qhov muag ua los ntawm cov iav fibers rau kev sib txuas lus hauv xov tooj kuj tau ua tiav tiav. Nws muaj lub peev xwm loj, kev sib kis tsawg tsawg, tsis cuam tshuam los ntawm electromagnetic cuam tshuam, tuaj yeem txuag tau tooj liab hlau, thiab tseem tuaj yeem xa cov duab rau TV thiab xov tooj.
Optical fiber ntau yog ib qho ntshiab thiab pob tshab iav fiber ntau nrog ib txoj kab uas hla ntawm tsuas yog li ntawm 1-100 μ m
Muaj tseeb ntau yam siv rau iav fiber ntau, thiab nrog kev txhim kho sai ntawm kev tshawb fawb thiab thev naus laus zis, iav fiber ntau yuav ua rau muaj txiaj ntsig ntau dua.
