Koj puas paub tias lub xeev tam sim no ntawm kev lag luam fiberglass zoo li cas?
Taw qhia rauiav Fiber
Cov iav fiber ntau yog ib qho kev ua haujlwm siab -kev ua haujlwm tsis muaj organic tsis yog- cov khoom siv hlau ua los ntawm cov khoom siv tsis zoo uas tsis yog- hlau xws li pyrophyllite, quartz xuab zeb, thiab limestone. Nws yog tsim los ntawm ib tug series ntawm cov txheej txheem nrog rau siab -kub melting, kos duab, thiab winding, raws li ib tug meej formula. Nws muaj cov txiaj ntsig zoo xws li cov khoom siv hluav taws xob zoo, lub zog ua haujlwm siab, muaj zog cua sov, thiab zoo corrosion kuj, thiab yog dav siv nyob rau hauv tsheb, electronics, cua zog tsim, shipbuilding, aerospace, kev tsim kho, roj av, thiab tshuaj industries. Nws yog feem ntau siv los ua cov khoom siv txhawb zog thiab siv ntau yam kev lag luam ua cov khoom sib xyaw.
Cov iav fiber ntau tuaj yeem muab faib ua ntau txoj hauv kev, suav nrog cov ntsiab lus ntawm alkali hlau oxide, cov khoom siv fiber ntau, txoj kab uas hla monofilament, thiab fiber ntau pom. Raws li tag nrho cov ntsiab lus ntawm alkali hlau oxides (feem ntau Na₂O thiab K₂O), nws tuaj yeem muab faib ua alkali-dawb iav fiber (E iav fiber), nruab nrab-alkali iav fiber (C iav fiber ntau), thiab siab -alkali iav fiber (A iav fiber).
E iav fiber ntau yog tsim los ntawm aluminoborosilicate nrog alkali hlau oxide cov ntsiab lus tsawg dua 1%. Thoob plaws ntiaj teb, ntau dua 90% ntawm iav fibers yog E- iav fiber.
E- iav fiber ntau muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv kho tshuab, tab sis cov kua qaub tsis zoo, ua rau nws tsis haum rau acidic ib puag ncig. Nws yog dav siv nyob rau hauv daim ntawv thov yuav tsum tau hluav taws xob rwb thaiv tsev los yog ua ib tug reinforcing khoom.
Nruab nrab-alkali iav fiber feem ntau muaj 8%–12% alkali hlau oxides. C- iav fiber ntau rau kwv yees li 5% ntawm tag nrho cov iav fiber ntau lawm. C- iav fiber ntau muaj cov kua qaub tiv thaiv, tab sis cov khoom siv hluav taws xob tsis zoo thiab cov khoom siv hluav taws xob qis dua E- iav fiber ntau. Txawm li cas los xij, nws tuaj yeem tiv taus cov tshuaj tiv thaiv corrosion thiab tuaj yeem siv rau hauv cov kua qaub cia tso tsheb hlau luam thiab cov khoom siv hluav taws xob, nrog rau cov khoom siv ntxiv rau asphalt vov tsev uas yuav tsum muaj zog dua.
A- iav fiber ntau feem ntau muaj 14.5% lossis siab dua alkali hlau oxides. A- iav fiber ntau muaj dej tsis zoo; Tom qab raug dej, cov khoom tsim los ntawm nws sai sai ua nkig thiab poob lub zog, ua rau nws siv tsis tau. Nws tau ua ntau theem tawm.
Mainstream Production Methods
Lub ntsiab ntau lawm txoj kev rau nruam iav fibers yog crucible drawing thiab tank rauv kos duab. Txoj kab uas hla ntawm cov iav fiber ntau monofilaments feem ntau yog 1.5μm ~ 25μm, feem ntau 4μm ~ 14μm.
(1) Crucible Drawing Method: Ua ntej, ntau yam khoom siv raw nrog cov txheej txheem tshwj xeeb yog crushed thiab tom qab ntawd ntxiv rau lub khob tank rauv, qhov uas lawv tau yaj ntawm qhov kub ntawm txog 1500 degree. Tom qab ntawd, iav spheres ntawm ib txoj kab uas hla yog tsim siv lub pob - ua tshuab (li no lub npe "pob txoj kev"). Cov iav spheres yog tom qab ntawd ntxiv rau lub crucible uas muaj platinum baffle phaj thiab remelted rau hauv ib tug spinning yaj, uas ntws tawm ntawm lub nozzle ntawm lub platinum baffle phaj thiab yog kos rau hauv tas li iav fibers. Txoj kev no muaj kev siv hluav taws xob ntau, kev ua haujlwm tsawg, thiab cov txheej txheem tsim tsis ruaj khov, thiab tau raug txiav tawm ntau.
(2) Tank Furnace Drawing Method: Txoj kev no tshem tawm lub pob - ua txheej txheem. Tom qab cov iav yaj ntws tawm ntawm lub qhov ntawm platinum-rhodium alloy ntxeem tau baffle phaj, nws tau kos rau hauv cov iav txuas ntxiv los ntawm lub siab - tshuab nqus tsev ceev. Lub resulting iav yaj yog ncaj qha mus rau hauv fibers, li no lub npe "direct drawing method" los yog "ib-kab ruam txoj kev." Tsis tas li ntawd, piv nrog rau txoj kev kos duab crucible, lub tank rauv txoj kev muaj peev xwm ntau lawm, cov txheej txheem tswj tau zoo dua, thiab cov khoom ruaj khov dua.
Keeb kwm ntawm Fiberglass Development
Hauv xyoo 1930, Owens -Illinois Glass Company thiab Corning Glass Factory tau koom ua ke los tsim Owens Corning Fiberglass Company. Tom qab Tsov Rog Ntiaj Teb Zaum II, kev lag luam fiberglass thoob ntiaj teb tau tsim kho sai, nrog kev txhim kho kev tsim khoom tsis tu ncua, ua rau muaj ntau lub tuam txhab fiberglass xws li PPG Industries (USA), Saint-Gobain Group (Fabkis), thiab Nittobo (Nyiv). kuv lub teb chaws txoj kev lag luam fiberglass pib nyob rau hauv 1958. Ua ntej kev hloov kho thiab qhib, nws yog tsuas yog siv rau lub teb chaws tiv thaiv thiab tub rog industries; Tom qab kev hloov kho thiab qhib, nws hloov mus rau kev siv pej xeem thiab txhim kho sai. Nrog kev nthuav dav ntawm kev lag luam kev xav tau, nyob rau xyoo tas los no, kuv lub teb chaws fiberglass yarn ntau lawm tau nce xyoo los ntawm xyoo. Hauv xyoo 2023, kuv lub teb chaws cov xov paj fiberglass tag nrho tau nce mus txog 7.23 lab tons, ib xyoos -ntawm -xyoo nce ntawm 5.2%.
Cov xwm txheej tam sim no thiab teeb meem
①. Cov nplai me me thiab qhov zoo ntawm -kev ua tau zoo iav fiber ntau thiab cov khoom sib xyaw ua ke tam sim no, kuv lub teb chaws cov iav fiber ntau tsim muaj peev xwm, cov khoom tsim tawm, thiab qib kev tsim khoom yog nyob rau hauv lub ntiaj teb no, tab sis nws ntsib ib qho teeb meem ntawm overcapacity thiab loj homogenization ntawm tsawg- khoom kawg, thaum siab - cov khoom kawg raug kev txom nyem los ntawm cov khoom tsis txaus thiab kev sib tw tsis muaj zog. Piv nrog rau qhov ntsuas ntawm siab -kev ua tau zoo iav fiber ntau ntau yam txawv teb chaws, qhov ntsuas ntawm ntau yam siab -kev ua tau zoo iav fiber ntau hauv kuv lub teb chaws yog me me. Tam sim no, cov zis ntau yam siab-kev ua tau zoo thiab tshwj xeeb iav fiber ntau yarns (tsis suav nrog siab-modulus thiab ultrafine yarns), xws li alkali-resistant, siab{11}}lub zog, qis-dielectric, tsis xwm yeem-zoo li tus, sib xyaw, thiab xim. siab-silica, quartz, thiab basalt yarns, tsuas yog kwv yees li 1% ntawm tag nrho cov iav fiber ntau tso tawm. Yog li ntawd, cov zis thiab qhov zoo ntawm siab -kev ua tau zoo iav fiber ntau thiab cov khoom tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev ua lag luam siab - kawg.
②. Tsis txaus R & D nyob rau hauv iav Fiber thiab cov khoom tsim Technology thiab khoom siv
Thaum kuv lub teb chaws cov iav fiber ntau tsim tshuab thiab cov cuab yeej siv tau los txog los yog mus txog qib siab thoob ntiaj teb, kev tsim cov iav fiber ntau siab -kev ua haujlwm tshwj xeeb, xws li siab- zog, qis-dielectric, thiab siab-silica hom, tseem ntsib cov teeb meem tseem ceeb hauv cov cim tseem ceeb xws li cov khoom siv hluav taws xob, hluav taws xob, thiab hluav taws xob tiv thaiv. Tsis tas li ntawd, cov thev naus laus zis tseem ceeb xws li kev tsim kho kom zoo ntawm siab -kev ua tau zoo iav fiber ntau cov khoom siv thiab kev ua haujlwm, cov neeg ua haujlwm loj thiab cov yeeb yaj kiab tshwj xeeb- ua cov neeg ua haujlwm, thiab kev sib sib zog nqus ntawm cov khoom fiber ntau tseem tsis muaj zog, thiab cov khoom siv ntau lawm qis, yog li cuam tshuam txoj kev loj hlob ntawm siab -kev ua tau zoo iav fibers ntawm kev lag luam loj-, kev tsim khoom loj.
③. Uneven Development ntawm Intelligent Manufacturing ntawm Enterprises
Cov tuam txhab ua lag luam thiab cov lag luam tseem ceeb hauv kev lag luam iav fiber ntau muab qhov tseem ceeb rau kev tsim khoom ntse, ua kom pom kev muaj zog thiab muaj peev xwm rau kev txawj ntse hloov kho tshiab, thiab nthuav tawm cov qib zoo heev thiab ua rau kev txhim kho ntse. Txawm li cas los xij, me me thiab nruab nrab- cov lag luam me, vim muaj qee yam xws li cov peev nyiaj tsawg, kev siv thev naus laus zis tsis txaus, thiab cov txuj ci tsis txaus, tsis muaj kev txhawb siab thiab muaj peev xwm los txhawb kev tsim khoom ntse. Cov tuam txhab lag luam no ntsib cov teeb meem thaum lawv hloov pauv kev txawj ntse, suav nrog tab sis tsis txwv rau cov cuab yeej siv siab hloov kho cov nqi, kev nyuaj rau kev yoog raws thiab kev paub txog cov thev naus laus zis tshiab, thiab siab kom tswj tau tus nqi kom zoo dua hauv kev sib tw ua lag luam. Yog li ntawd, lawv tsis muaj kev txhawb siab los nqis peev hauv kev txawj ntse kho dua tshiab thiab hloov pauv, ua rau kev txhim kho ntse qeeb.
