Nyob rau hauv tus txheej txheem ntawm kev kos duab fiberglass nyob rau hauv lub tank rauv, yog vim li cas yog cov fiber hauv paus ntsiab lus tseem ceeb rau fiberglass txoj kev?
Basic Principles of Fiber forming
Nyob rau hauv lub tank furnace fiber ntau daim duab txheej txheem, molten iav, nyob rau hauv hydrostatic siab, ntws tawm nyob rau hauv tee los ntawm ib tug precision nozzle nyob rau hauv qab ntawm ib tug platinum alloy baffle. Lub tshuab nqus tsev siab - nrawm nrawm, nyob ncaj qha hauv qab lub nozzle, tig ntawm qhov kev kub ceev tsis tu ncua, siv lub zog ncab rau cov iav poob. Tus yuam sij rau cov txheej txheem no yog nyob rau hauv qhov sib npaug ntawm qhov sib npaug ntawm qhov chaw tawm ntawm qhov dej tawm - lub hauv paus fiber ntau:
1. Fiber hauv paus tsim:
Hauv qab lub nozzle tawm, qhov nro ntawm lub iav molten (sim ua kom lub tee ntawm lub raj kheej kheej) thiab lub zog ncab ntawm lub tshuab nqus tsev (sim ua kom ncav lub tee dej) ncav cuag qhov sib npaug zoo. Qhov no ua rau cov iav molten tsim ib qho tshwj xeeb, crescent - zoo li cheeb tsam ntawm lub nozzle tawm. Txoj kab uas hla ntawm cheeb tsam no maj mam tapers los ntawm lub nozzle tawm.
2. Fiber ntau txoj kab:
Qhov kev ncua deb ntawm lub nozzle tawm mus txog rau thaum lub iav molten yog stretched thiab solidified, thiab lub fiber txoj kab uas hla mus txog nws zaum kawg thiab tsis muaj -ntev - hloov point, yog hu ua fiber ntau txoj kab. Qhov chaw encompassing kab no yog lub fiber ntau forming tsam. Nyob rau hauv cheeb tsam no, cov iav molten dhau qhov kev hloov pauv loj heev, ua kom muaj zog los ntawm cov kua dej khov rau hauv cov khoom fibers.
3. Fiber kos duab kab:
Qhov no yog hais txog tag nrho qhov kev ncua deb ntawm lub qhov hluav taws xob nozzle mus rau qhov chaw fiber ntau winding ntawm lub tshuab kos duab. Qhov kev ncua deb no tuaj yeem hloov kho manually raws li cov txheej txheem yuav tsum tau ua (xws li kev xav tau cua txias thiab chaw ua haujlwm), thiab feem ntau yog ntev dua li qhov tseeb fiber ntau txoj kab ntev.
Kev ruaj ntseg ntawm cov hauv paus fiber ntau thiab fiber ntau txoj kab yog qhov txiav txim siab ua kom muaj siab - iav fiber ntau, cuam tshuam ncaj qha:
◉ Uniformity ntawm fiber ntau txoj kab uas hla
◉ Tus nqi tawg
◉ Ntau lawm efficiency thiab nqi
Cov txheej txheem tseem ceeb tsis cuam tshuam rau txoj kev ruaj ntseg:
* Cov kua dej theem: Txiav txim siab lub siab hydrostatic ntawm lub iav molten ntawm lub nozzle, cuam tshuam tus nqi tawm thiab pib fiber ntau hauv paus morphology.
* Shutter kub: Precisely tswj lub viscosity ntawm molten iav yog qhov tseem ceeb kom tau txais cov khoom tsim tensile.
* Kev kos duab nrawm: ncaj qha txiav txim siab qhov loj ntawm lub zog rub thiab qhov kawg ntawm txoj kab uas hla.
* Molten iav zog: Tshuaj muaj pes tsawg leeg txiav txim siab nws cov viscosity -tus yam ntxwv kub, nto nro, crystallization nyiam, thiab lwm yam.
* Txias tej yam kev mob: cuam tshuam qhov kub gradient thiab solidification tus nqi nyob rau hauv lub fiber hauv paus cheeb tsam, tseem ceeb heev rau stability thiab fiber ntau.
* Kos piv: Qhov piv ntawm lub nozzle orifice txoj kab uas hla mus rau qhov kawg fiber inch, xav txog cov℃ntawm kev kos duab.
Airflow tswj: cuam tshuam qhov kub ntawm qhov chaw faib khoom thiab kev ua kom txias hauv thaj av fiber ntau.
Pas Dej Rauv Fiber Drawing Txheej Txheem Khoom thiab Layout
Kev ua tiav qhov ruaj khov thiab ua tau zoo fiber ntau yog nyob ntawm cov txheej txheem ntawm cov khoom siv tau yooj yim tau teem tseg (los ntawm sab saum toj mus rau hauv qab):
1. Spindle:
Muaj thiab tswj qhov kub thiab txias ntawm molten iav, thiab tswj cov ntws ntawm molten iav los ntawm lub spout.
2. Fiber hauv paus Cooler:
Nyob ncaj qha rau hauv qab ntawm spindle, ze rau thaj tsam fiber ntau. Feem ntau siv cov cua txias (siab-cov ntaub thaiv cua txias) los yog dej txias (indirectly) kom sai thiab tswj tau quab yuam- txias qhov siab - kub, viscous fiber hauv paus, accelerating lub solidification thiab shaping ntawm lub molten iav. Nws yog ib qho tseem ceeb ntawm cov cuab yeej rau stabilizing cov hauv paus hniav fiber.
3. Raw Fiber Sprayer:
Tom qab cov fiber ntau tau pib solidified, nws txau dej pos huab los yog cua rau nws rau kev pab txias.
4. Monofilament Oiler:
Ua ntej cov monofilaments yog bundled rau hauv raw filaments, ib tug wetting tus neeg saib xyuas (bundling agent, lubricant, coupling agent, thiab lwm yam) yog uniformly thov rau saum npoo ntawm txhua monofilament. Tus neeg sawv cev sizing plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov fibers, bundling lawv mus rau hauv strands, thiab khi lawv mus rau cov khoom sib xyaw tom ntej.
5. Bundle:
Xyuas kom meej tias cov monofilaments ntws los ntawm cov nozzles sib txawv yog sib cais, tiv thaiv lawv los ntawm kev sib tsoo los yog sib tsoo.
6. Bundle:
Maj mam bundling ntau oiled thiab bundled monofilaments (feem ntau kaum rau txhiab) mus rau hauv ib tug nruam filament.
7. Slow-Pull Roller:
Nyob rau hauv qab ntawm lub bundler, nws siv me ntsis nro rau lub bundled filament, cia nws mus smoothly hloov mus rau lub siab -ceev kos duab cheeb tsam.
8. Airflow Diffuser:
Nyob rau saum toj ntawm lub tshuab nqus tsev nqus, nws disperses los yog coj lub airflow, tiv thaiv turbulence generated los ntawm lub siab -speed rotating drawing tshuab taub hau los ntawm kev cuam tshuam nrog kev ruaj ntseg ntawm cov fibers saum toj no.
9. Tshuab kos duab:
Lub zog tseem ceeb ntawm txoj kev tsim. Nws lub siab -ceev tig lub taub hau (winding lub taub hau) tsim muaj zog kos duab quab yuam, ncab lub iav molten rau hauv fibers thiab winding lub solidified filament rau hauv ib tug bobbin (xov paj). Cov txheej txheem txoj hauj lwm txoj kab yog hais txog cov txheeb ze ntsug thiab kab rov tav layout ntawm aforementioned cov khoom tseem ceeb (feem ntau yog stencil, oiler, bundler, kos duab tshuab winding log, thiab lub taub hau). Qhov kev tsim qauv no ncaj qha cuam tshuam rau fiber ntau txoj kev khiav, nro faib, thiab ua kom txias.
Ib qho - txheej txheej: Txhua qhov kev ua haujlwm (los ntawm stencil mus rau winding) yog ua tiav ntawm tib lub dav hlau khiav haujlwm. Cov qauv yog qhov yooj yim, tab sis qhov chaw ua haujlwm yuav raug txwv.
Muab ob npaug rau- txheej txheej txheej: Cov txheej txheem tau muab faib ua thaj chaw ua haujlwm sab saud thiab sab qis (feem ntau nyob rau hauv lub tank loj rauv taws teeb kos kab). Sab qaum teb: Feem ntau suav nrog cov stencil, fiber ntau txias, sprayer, oiler, bundler, thiab bundler, rau siab - kub sib sau thiab kev kho mob ua ntej.
Cov cheeb tsam qis: Feem ntau suav nrog qeeb - kos cov menyuam, airflow diffuser, thiab tshuab kos duab rau fiber ntau winding. Qhov layout no optimizes qhov chaw siv, txhim kho kev khiav hauj lwm ib puag ncig (tshwj xeeb tshaj yog kev rho tawm ntawm qhov siab -kub cheeb tsam), thiab pab automation.
Cov ntsiab lus
Cov iav fiber ntau tsim yog ib qho kev kos duab ntawm qhov sib npaug ntawm qhov nro thiab lub zog tensile ntawm qhov kub thiab txias. Nkag siab txog kev tsim thiab ruaj khov mechanism ntawm "fiber roots" yog lub hauv paus ntawm kev paub txog cov txheej txheem. Los ntawm kev tswj hwm qhov tseem ceeb xws li qib ua kua, qhov kub thiab txias, thiab kev ua kom txias, thiab siv cov cuab yeej siv tau zoo uas muaj lub phaj baffle, txias, oiler, bundler rau kev kos duab, nrog rau qhov tsim nyog "txhim kho txoj haujlwm kab" tsim, viscous molten iav tuaj yeem ua tau zoo thiab ruaj khov hloov mus rau siab {2} fiber ntau txuas ntxiv.
