Dab tsi yog cov ntawv fiberglass ntau, koj puas paub?
Nws feem ntau hais tias fiberglass yuav txais cov ntaub ntawv sib txawv raws li cov khoom sib txawv, cov txheej txheem thiab kev ua haujlwm ntawm kev siv, thiaj li ua tiav kev siv sib txawv.
Niaj hnub no peb yuav tham txog ntau hom iav fiber ntau.
1. Twistless Roving
Untwisted roving yog muab faib mus rau hauv ncaj qha untwisted roving thiab plied untwisted roving. Direct yarn yog cov fiber ntau txuas ncaj qha los ntawm iav yaj, tseem hu ua ib leeg-strand untwisted roving. Cov xov paj plied yog cov xuab zeb ntxhib ua los ntawm ntau qhov sib npaug sib npaug, uas tsuas yog kev sib txuas ntawm ntau cov xov paj ncaj qha.
Qhia rau koj me ntsis ua kom yuam kev, yuav ua li cas kom paub qhov txawv ntawm cov xov paj ncaj ncaj thiab cov xov paj ntaub? Ib strand ntawm xov paj yog kos tawm thiab co sai sai. Ib qho uas tseem tshuav yog cov xov paj ncaj, thiab ib qho uas tau tawg mus rau hauv ntau cov strands yog cov xov paj.
2. Tej xov paj
Bulked yarn yog tsim los ntawm kev cuam tshuam thiab cuam tshuam cov iav fibers nrog cov cua compressed, kom cov fibers hauv cov xov paj sib cais thiab qhov ntim tau nce, kom nws muaj ob qho tib si lub zog ntawm cov fibers tas li thiab qhov loj ntawm cov fibers luv.
3. Plain weave ntaub
Gingham yog ib qho roving dawb weave ntaub, warp thiab weft yog interlaced ntawm 90 ° nce thiab nqis, los yog woven ntaub. Lub zog ntawm gingham feem ntau yog nyob rau hauv warp thiab weft cov lus qhia.
4. Axial ntaub
Axial ntaub yog tsim los ntawm weaving iav fiber ncaj untwisted roving ntawm ib tug multi-axial braiding tshuab. Cov kaum feem ntau yog 0°,90 ib°, 45° , -45 ib° , uas tau muab faib ua unidirectional daim ntaub, biaxial daim ntaub, triaxial daim ntaub thiab quadriaxial daim ntaub raws li tus naj npawb ntawm txheej.
5. Fiberglass lev
Fiberglass mats tau sau npe hu ua“xav”, uas yog cov ntawv zoo li cov khoom ua los ntawm cov hlua txuas ntxiv los yog cov hlua khi uas tsis yog-directionally khi ua ke los ntawm cov tshuaj binders lossis mechanical action . Felts tau muab faib ua cov mats strand, stitched mats, composite mats, nruam mats, nto mats, thiab lwm yam. Cov ntaub ntawv tseem ceeb: pultrusion, winding, molding, RTM, nqus induction, GMT, thiab lwm yam.
6. Txiav strands
Cov xov paj fiberglass yog chopped rau hauv cov strands ntawm ib qho ntev. Cov ntawv thov tseem ceeb: ntub dej (txhim kho gypsum, ntub dej nyias), B MC, thiab lwm yam.
7. grinded tws fibers
Nws yog tsim los ntawm kev sib tsoo cov fibers hauv ib lub rauj zeb los yog pob zeb. Nws tuaj yeem siv los ua tus muab tub lim los txhim kho resin nto phenomenon thiab txo resin shrinkage.
Cov saum toj no yog ob peb hom fiberglass uas tau qhia lub sijhawm no. Tom qab nyeem cov ntawv ntawm cov iav fiber ntau, kuv ntseeg tias peb txoj kev nkag siab ntawm nws yuav mus ntxiv.
Niaj hnub no, fiberglass tam sim no yog cov khoom siv siv ntau tshaj plaws, thiab nws daim ntawv thov yog paub tab thiab dav, thiab muaj ntau hom. Raws li qhov no, nws yooj yim dua los nkag siab txog thaj chaw ntawm daim ntawv thov thiab cov ntaub ntawv sib xyaw ua ke.
