Cov cuab yeej, kev siv, thiab npe cov lus pom zoo ntawm Fiberglass Untwisted Roving
Untwistedfiberglass rov, raws li cov khoom siv tseem ceeb hauv cov ntaub ntawv sib xyaw, tsis yog tsuas yog khav theeb ntau hom kev faib tawm, tab sis nws cov khoom tshwj xeeb, kev siv dav, thiab cov txheej txheem naming kuj yog nws cov txiaj ntsig tseem ceeb. Cov hauv qab no yuav piav qhia txog nws cov yam ntxwv, thaj chaw thov, thiab cov cai teev npe.
Cov yam ntxwv tseem ceeb ntawm Untwisted Fiberglass Roving
Untwisted fiberglass roving muaj cov txiaj ntsig tseem ceeb vim nws cov qauv tshwj xeeb thiab cov txheej txheem tsim khoom:
1. Uniform thiab Regular Structure: Cov ntaub thickness yog uniform, thiab warp thiab weft yarns yog tiaj tus thiab sib npaug heev nyob rau hauv cov ntaub nto, xyuas kom meej cov khoom zoo ib yam.
2. Economical thiab Efficient: Cov txheej txheem tsim yog luv luv, ua rau muaj kev ua haujlwm siab thiab txo cov nqi tsim khoom.
3. Dimensional Stability and Convenient Handling: The high fiber density gives the fabric excellent dimensional stability and resistance to deformation, making it easier to control during cutting, laying, and other operations.
4. Cov Khoom Siv Zoo Tshaj Plaws: Txij li cov fiberglass yarn yog untwisted, cov fiberglass bundles nyob twj ywm xoob, cia resins (xws li unsaturated polyester, vinyl ester, epoxy, phenolic resin, thiab lwm yam) kom sai nkag mus thiab ntub cov ntaub, zoo heev txhim kho kev tsim kho thiab cov khoom zoo.
5. Kev ua tau zoo heev: Nws muaj cov cuab yeej lamination zoo heev (cov khoom siv molding), ua kom nws nruj nruj rau cov pwm pwm; ib txhij, nws zoo defoaming kev ua tau zoo pab txo cov pa npuas tsis xws luag hauv cov khoom.
6. Cov khoom siv hluav taws xob siab thiab lub teeb xa hluav taws xob: Cov khoom siv sib xyaw ua rau pom muaj zog tensile thiab flexural zog, thaum tseem muaj cov pob tshab zoo (tshwj xeeb yog tsim rau cov vaj huam sib luag translucent).
7. Cov ntsiab lus fiber ntau: Muab piv rau ntau hom mats (xws li tws strand lev thiab nruam lev), nws tuaj yeem ua tiav cov ntsiab lus fiber ntau dua, txog li 65%, uas tso cai rau cov fiber ntau ntxiv.
8. Interlaminar kev ua tau zoo xav txog thiab cov kev daws teeb meem: Nws qhov kev txwv tseem ceeb nyob hauv qhov qis interlaminar shear zog ntawm cov khoom. Txhawm rau kov yeej qhov no, hauv kev xyaum ua haujlwm engineering, nws feem ntau siv hloov pauv nrog fiberglass lev (xws li chopped strand lev lossis deg lev). Qhov kev sib xyaw ua ke no ua rau txhim kho qhov delamination tsis kam ntawm FRP cov khoom.
Kev siv dav ntawm Untwisted Fiberglass Roving
Vim nws cov khoom zoo heev, untwisted roving plays lub luag haujlwm tseem ceeb hauv cov txheej txheem molding cov khoom sib xyaw:
Cov txheej txheem Moulding tseem ceeb: Tshwj xeeb yog tsim rau tes nteg - nce molding thiab ntau lwm yam txheej txheem molding.
Cov cheeb tsam tseem ceeb ntawm kev thov:
Kev thauj mus los: Lub nkoj hulls thiab cov khoom siv, tsheb lub cev panels, bumpers, tsheb fairings, rail transit Cheebtsam, aircraft internal structural qhov chaw, thiab lwm yam.
Kev tiv thaiv tshuaj lom neeg thiab ib puag ncig: Ntau lub tso tsheb hlau luam thiab cov thawv ntim khoom (xws li, cov chaw khaws tshuaj chemical, lub tank kho dej), lub qhov cua ducts, cov tshuaj txhuam hniav, cov kab hluav taws xob.
Kev tsim kho thiab cov khoom siv hauv tsev: Skylights, ru tsev, phab ntsa, cov khoom siv huv huv (chaw da dej, chav da dej), cua txias ntauwd panels, rooj tog zaum.
Lub zog thiab kev lag luam: Cua turbine hniav, cov khoom siv hluav taws xob rwb thaiv tsev, cov khoom siv tiv thaiv npog, cov khoom ua si (xws li, surfboards, skis, nuv ntses rods).
Resin Compatibility: Kev sib raug zoo nrog cov thermosetting resin systems, suav nrog unsaturated polyester resins (UPR), vinyl ester resins (VER), epoxy resins (EP), thiab phenolic resins (PF).
Lub npe thiab Specifications ntawm Fiberglass Woven Fabrics (nrog rau Untwisted Roving)
Txhawm rau txheeb xyuas cov khoom lag luam, fiberglass woven fabrics (xws li untwisted roving) ua raws li cov cai tshwj xeeb, feem ntau muaj ntau yam. Piv txwv li, 'EWR400-1000' tau piav qhia hauv qab no:
'E': Hais txog hom iav siv. `E` qhia tias alkali-dawb fiberglass (E- iav). Lwm cov lej muaj xws li `C` (nruab nrab-alkali iav), `AR` (alkali- iav tiv thaiv), `S`, lossis `HMG` (siab-lub zog / siab- iav modulus).
'WR': Hais txog hom ntaub. 'WR' yog tus qauv luv luv rau Woven Roving. Lwm hom muaj xws li 'WB' (plain weave), 'WT' (twill weave), thiab lwm yam.
'400': Sawv cev ntawm cov ntaub thaj tsam loj (grams ib square meter), qhia hauv grams ib square meter (g / m²). Tus nqi no sawv cev qhov hnyav ntawm cov ntaub ib square meter thiab yog ib qho tseem ceeb qhia txog ntaub specifications thiab fiber ntau.
`-`: Separator.
'1000': Sawv cev ntawm cov ntaub dav hauv millimeters (mm). Tus nqi no qhia txog tus qauv dav ntawm cov ntaub thaum lub sijhawm tsim khoom.
fiberglass untwisted roving, nrog nws cov du thiab zoo ib yam, resin impregnation ceev, siab fiber ntau cov ntsiab lus, zoo heev zog, thiab superior moldability, tau dhau los ua ib qho indispensable reinforcing substrate nyob rau hauv lub teb ntawm cov ntaub ntawv sib xyaw. Nws daim ntawv thov yog dav heev, xws li los ntawm kev tsim nkoj thiab tsheb mus rau cua turbine hniav thiab cov khoom siv tshuaj. Kev nkag siab txog nws cov qauv naming cov cai (piv txwv li, `EWR400-1000`) yog qhov tseem ceeb rau kev xaiv cov khoom raug, ua kom cov khoom zoo, thiab ua tiav cov txheej txheem. Hauv kev siv tswv yim, xav txog nws qhov kev ua tau zoo ntawm interlayer, nws feem ntau yog siv los ua ke nrog cov ntaub ntawv xav tau kom ua tiav cov txiaj ntsig zoo ntawm cov ntaub ntawv sib xyaw thiab ua tau raws li ntau haiv neeg, siab - kev ua tau zoo kawg nkaus xav tau.
