Tshawb nrhiav cov lus zais ntawm fiberglass txiav- ntug tshuab?
Los ntawm cov hniav loj heev ntawm lub zog tshiab cua turbines mus rau lub teeb yuag ntawm lub zog tshiab tsheb thiab qhov tseeb Circuit Court boards ntawm cov khoom siv hluav taws xob,fiberglasscomposites yog permeating txhua yam ntawm lub neej raws li "invisible powerhouses." Niaj hnub no, peb dissect tag nrhofiberglassmuab cov saw hlau los ntawm kev tsim khoom mus rau daim ntawv thov, nthuav tawm yuav ua li cas polymer physics ua rau ib leeg ib leeg fiberglass kom muaj peev xwm rub tawm ntau txhiab tons.
Polymer Physical Structure ntawm GFRP
Lub hauv paus ntawmfiberglassreinforced polymer (GFRP) yog kev sib koom ua ke tsim ntawm "theem txhawb zog (fiberglass) + matrix theem (polymer resin)," ib qho kev tshwm sim ntawm lub hauv paus ntsiab lus uas "cov qauv txiav txim siab ua tau zoo" hauv cov khoom siv polymer.
Lub "fiber{0}}resin" composite system:
Cov tshuaj muaj pes tsawg leeg ntawm fiberglass yog tib yam li cov iav, feem ntau yog tsim ntawm silicon dioxide (SiO2), boron trioxide (B2O3), thiab hlau oxides xws li sodium, potassium, barium, thiab txhuas. fiberglasss feem ntau yog tsim los ntawm ores xws li wollastonite thiab calcite, melted ntawm 1500 degree, thiab ces kos rau hauv fibers los ua ib tug amorphous SiO₂ covalent network qauv- cov qauv no endows lawv nrog ib tug ultra- siab elastic modulus.
Los ntawm cov kev xav ntawm lub cev polymer, qhov rigidity ntawm fiberglass yog los ntawm cov nyiaj siab zog ntawm covalent bonds, thiab cov qauv amorphous zam kev hloov pauv ntawm cov khoom siv lead ua tsis xws luag, dhau los ua "kev txhawb nqa tshuab" ntawm cov khoom sib xyaw.
Performance Advantages thiab Applications
1. Cua Turbine Blades
Qhov zoo: Lub zog muaj zog modulus (101 GPa) - sib npaug rau 1cm inch fiberglass pas nrig rub ntau tshaj 1000 tons thiab tseem rov qab los rau nws cov qauv qub.
High softening point kub (970 degree) thiab qis coefficient ntawm expansion.
tuaj yeem txo cov hniav deformation, hniav hnyav, thiab cov nqi tsim hluav taws xob nyob rau hauv tib lub zog cua.
2. Khoom siv hauv tsev
Qhov zoo: Lub zog loj, lub teeb yuag, kev laus ua haujlwm, thiab cov nplaim hluav taws zoo.
tuaj yeem txhim kho pob zeb, cov khoom siv phab ntsa, cov ntxaij vab tshaus thermal, thiab kho kom zoo nkauj, thiab lwm yam.
3. Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob
Qhov zoo: hluav taws xob rwb thaiv tsev, corrosion kuj, rwb thaiv tsev kub.
Kev tsim khoom: Cov ntawv luam tawm Circuit Court boards, hluav taws xob enclosures, hluav taws xob hloov lub thawv, insulators, thiab lwm yam.
Cov txheej txheem ntau lawm
Crucible Drawing Method: Ob-theem forming. Cov ntaub ntawv nyoos yog crushed thiab tom qab ntawd ntxiv rau lub khob da dej rauv, qhov chaw uas lawv tau yaj ntawm kwv yees li 1500 degree. Cov iav spheres ntawm ib txoj kab uas hla tshwj xeeb yog tsim los siv lub tshuab pelletizing. Cov spheres no tau ntxiv rau lub crucible uas muaj platinum stencil thiab remelted los ua ib tug spinning yaj, uas ntws tawm los ntawm lub stencil nozzle thiab kos rau hauv fiberglass tas mus li.
Batter Furnace Drawing Method: Ib qho -theem forming. Piv nrog rau txoj kev kos duab crucible, cov txheej txheem pelletizing raug tshem tawm. Tom qab cov iav molten ntws tawm ntawm lub qhov perforated ntawm lub platinum-rhodium alloy stencil, nws tau kos rau hauv cov iav txuas ntxiv los ntawm lub siab - tshuab nqus tsev ceev.
Cov qauv no tsis yog tsuas yog muaj txiaj ntsig zoo xws li cov txheej txheem yooj yim, kev siv hluav taws xob tsawg, platinum tsawg- siv cov germanium alloy, zoo iav melting zoo, kev ua haujlwm siab, thiab cov nqi tsim khoom qis, tab sis cov chav da dej yog qhov cub hluav taws xob tsis tu ncua, haum rau loj - nplai ntau lawm.
Xaus
Txhua qhov kev hloov kho tshiab hauv kev lag luam fiberglass sawv cev rau kev sib sib zog nqus ntawm polymer physics cov hauv paus ntsiab lus thiab kev ua lag luam -cov qauv saw hlau txiav txim siab tawv, kev sib cuam tshuam cuam tshuam rau lub zog, thiab cov txheej txheem ua kom zoo dua kom ruaj ntseg.
Nrog rau kev txhawb nqa cov cai xws li lub zog tshiab thiab cov pa roj carbon nruab nrab, fiberglass cov ntaub ntawv sib xyaw yuav txhim kho mus rau "siab dua modulus, tus nqi qis dua, thiab ntau tus phooj ywg ib puag ncig" cov lus qhia, thaum polymer physics yuav txuas ntxiv los ua cov kev txhawb nqa tseem ceeb, qhib kev ua haujlwm ntau dua.
