Fiberglass Chopped Strand Mat: Kev tawg ntawm cov txheej txheem los ntawm Raw Ore kom tiav Mat
I. Core Raw Materials: Los ntawm Ore mus rau Molten Glass
Qhov pib taw tes rauchopped strand levyog alkali-dawb iav raw cov ntaub ntawv, feem ntau muaj xws li quartz xuab zeb, pyrophyllite, limestone, dej qab zib tshauv, thiab borosilicate, precisely proportioned raws li ib tug formula. Cov ntaub ntawv nyoos no yog crushed, sieved, hnyav, thiab tom qab ntawd muab tso rau hauv lub cub tawg, qhov chaw uas lawv tau yaj ntawm qhov kub siab tshaj 1200℃rau hauv ib lub khob thiab pob tshab molten iav, tshem tawm cov npuas npuas thiab impurities kom ruaj khov tom qab fiber ntau daim duab.
Ib txhij, sizing agents thiab binders yog npaj: sizing agents tiv thaiv cov fibers tom qab kos thiab txhim kho dispersibility thiab resin compatibility; binders, muaj nyob rau hauv emulsion thiab hmoov hom, txiav txim siab cov khoom tiav qhov kev xav, impregnation ceev, thiab daim ntawv thov, thiab yog cov khoom tseem ceeb rau kev tsim.
II. Fiber Drawing thiab Forming: Molten iav rau Nruam Fibers
Cov iav molten yog kos los ntawm platinum-rhodium alloy spinneret ntawm kev kub ceev mus rau hauv cov iav txuas ntxiv nrog txoj kab uas hla ntawm 9-13 μm. Cov filaments ib leeg no zoo heev thiab muaj zog heev. Tam sim ntawd tom qab kos duab, tus neeg sawv cev sizing yog thov, thiab tom qab ziab, untwisted rovings raug tsim, uas yog cov khoom siv ncaj qha rau cov khoom siv strand lev.
Cov kauj ruam no txiav txim siab fiber ntau zog, filament kom muaj nuj nqis, thiab pob cohesion, ncaj qha cuam tshuam qhov sib xws ntawm kev sib tsoo thiab lub vev xaib.
III. Chopping thiab Web Laying: Fibers Ua ib "Felt Substrate"
Cov fibers nyoos nkag mus rau hauv cov khoom siv chopping thiab raug txiav kom raug raws li tus qauv 50mm ntev. Cov txheej txheem chopping yuav tsum tsis txhob xoob fibers, thiab tsis muaj fibers uas ntev dhau los lossis luv dhau.
Cov chopped fibers yog conveyed los ntawm airflow los yog txhua yam txhais tau tias mus rau hauv lub settling chamber, qhov twg lawv tau nteg tawm randomly thiab tusyees ntawm ib tug stainless hlau mesh siv, tsim ib tug xoob fiber web web. The core control is the areal density (commonly 225g/㎡, 300g/㎡, 450g/㎡), ensuring consistent thickness and uniformity, without any uneven patches.
IV. Siv Adhesive thiab ziab / Kho
Lub web nteg fiber ntau nkag mus rau hauv seem kev sib txuas:
- Emulsion Felt: Emulsion nplaum yog tusyees txau rau, ua rau muaj kev nkag tau zoo dua thiab kev ntxhib los mos me ntsis;
- Powder Felt: Cov hmoov nplaum nplaum sib npaug sib npaug rau sab saum toj, muab kev yooj yim zoo thiab cov txheej txheem thov qhuav.
Tom qab ntawd cov ntaub ntawv muab tso rau hauv qhov cub kom qhuav thiab kho qhov kub ntawm 120-180℃los kho cov nplaum, kom cov fibers tau ruaj khov rau hauv daim ntawv ua tiav, thaum tib lub sijhawm tshem cov dej noo thiab teeb tsa cov duab. Kub thiab ceev yog tswj nyob rau hauv lub voj kaw kom tsis txhob overheating, nyob rau hauv - kho, los yog deformation.
V. Ncej- txheej txheem: Txias nias, ntug trimming, thiab hla- txiav
Cov kev kho mob yog thawj zaug compacted los ntawm txias - nias rollers los txhim kho flatness thiab hnov; Tom qab ntawd, cov npoo raug txiav kom tshem tawm fuzz thiab xyuas kom meej qhov dav (feem ntau 1040mm, 2500mm, thiab lwm yam); Thaum kawg, nws yog hla- txiav mus rau qhov ntev txiav txim kom tau txais cov nplooj ntawv lossis cov yob txuas ntxiv.
Cov kauj ruam no hloov cov khoom ib nrab-cov khoom tiav rau hauv cov qauv, npaj tau-rau- siv cov khoom lag luam- qib khoom tiav.
VI. Kev soj ntsuam zoo, winding, thiab ntim
The finished product undergoes online inspection: surface density, thickness, uniformity, bond strength, fuzz, stains, width, etc., with each item being checked individually; cov khoom tsis tsim nyog raug tso tseg. Cov khoom tsim nyog tau raug muab dov, kaw hauv cov dej noo-cov ntaub ntawv pov thawj thiab cov thawv ntawv / pallets, thiab sau npe nrog cov lus qhia tshwj xeeb, qhov hnyav, batch naj npawb, thiab hnub tsim khoom ua ntej khaws cia thiab xa tawm.
Tag nrho cov txheej txheem yog tiv thaiv los ntawm ya raws, siab, thiab tshav ntuj kom ruaj khov kev ua tau zoo thaum thauj thiab khaws cia.
VII. Ua tiav Chopped Strand Mat: Kev ua tau zoo thiab kev siv
Tsim nyog tws strand lev muaj plaub qhov zoo:
1. Isotropic: Tsis yog- kev taw qhia kev faib tawm, lub zog tsis sib xws;
2. Resin- phooj ywg: ceev impregnation, yooj yim degassing, thiab resin txuag;
3. Kev tsim kho kom haum: zoo moldability, yooj yim txiav, haum rau tes nteg -up/SMC/ molding;
4. Corrosion thiab rwb thaiv tsev tsis kam: Alkali-dawb iav fiber ntau tiv taus acids thiab alkalis, zoo heev hluav taws xob rwb thaiv tsev.
Npog cov ntawv thov hauv chav da dej, tshuaj tiv thaiv corrosion-cov kav dej, cov tso tsheb hlau luam, lub zog tshiab tsheb, cua turbine hniav, cov khoom siv hauv tsev, cov khoom siv rwb thaiv tsev, thiab lwm yam xwm txheej.
