Fiberglass yog cov khoom siv paub zoo uas siv rau hauv ntau qhov chaw ntawm kev lag luam, kev tsim nkoj thiab tsheb. Nws hom nto moo tshaj plaws thiab nrov tshaj plaws yog cov qauv fiberglass. Feem ntau nws yog siv rau pasting.

Ntse

Cov khoom siv no txawv, vim nws cov khoom siv kho tshuab. Cov qauv fiberglass tuaj yeem muaj qhov sib txawv thicknesses thiab ntom. Cov khoom siv ntom ntom muab lub zog siab rau cov khoom tiav, tab sis nws yuav tsum tso cai rau cov resin nkag tau yooj yim rau hauv cov qauv ntaub thiab qhwv cov fiberglass zoo. Qhov no yog qhov ua rau nws tuaj yeem tau txais cov khoom tsis sib cais uas muaj ntau yam zoo.

Rau lub hom phiaj ntawm impregnation siab dua nrog cov resin, cov qauv fiberglass yog pre-impregnated nrog cov neeg ua haujlwm tshwj xeeb - lubricants uas txhim kho adhesion nrog ntau hom resins, tshwj xeeb tshaj yog epoxy thiab polyester. Nyob rau hauv rooj plaub thaum cov kev xav tau rau lub zog ntawm cov khoom tsis siab dhau, kom tau txais fiberglass qhov chawcov ntaub ntawv uas tsis yog-woven, hu ua iav mats, tuaj yeem siv tau. Lawv muaj xws li randomly txheej txheem ntawm iav roving, uas yog, ib pob ntawm iav fibers. Cov ntaub ntawv no yog tus cwj pwm los ntawm qhov muaj peev xwm nqus tau zoo heev ntawm cov resin. Ua tsaug rau lawv, koj tuaj yeem tau txais cov khoom sib xws tau yooj yim dua.

Ntawm cov qauv fiberglass raws li GOST muaj qhov tshiab - qhov no yog cov khoom siv los ntawm hollow fiberglass. Txhua fiber yog ib lub raj ntawm microscopic txoj kab uas hla, tsis yog ib tug pas nrig. Raws li qhov tshwm sim, cov khoom muaj lub zog zoo sib xws, tab sis sib zog los ntawm 20-30%. Lub Scope ntawm cov khoom no yog dav. Nws yog qhov yuav tsum tau nyob qhov twg qhov hnyav ua lub luag haujlwm tseem ceeb, tshwj xeeb tshaj yog hauv kev tsim kho tsheb, aviation thiab lwm yam.

txiaj ntsig

Cov qauv fiberglass raws li GOST hauv kev sib piv nrog cov qauv fiberglass yog qhov txawv ntawm qhov ruaj khov thiab yoog raws. Nws kuj muaj cov khoom nram qab no:

• kev nyab xeeb hluav taws;
• lub neej ua haujlwm ntev;
• tshuaj thiab corrosion kuj;
• sustainable;
• muaj peev xwm thov ntawm qhov kub ntawm -200 ° C txog + 550 ° C;
• hnav tsis kam.

thaj chaw thov

Cov qauv fiberglass yog qhov txawv ntawm nws tus nqi tsim nyog vim nws cov khoom siv. Cov khoom no feem ntau siv sib npaug:

• ntawm cov kab ntau lawm uas yuav tsum tau muaj qhov tseeb thiab lub zog - cov khoom siv rau cov khoom siv hauv chaw thiab cov khoom siv dav hlauspheres;
• nyob rau hauv tsev neeg - kev kho tsheb, kev tsim kho thiab kav dej.

Cov ntaub, uas yog ua los ntawm E thiab C qeb iav threads, ncaj qha lubricant thiab paraffin emulsion, tau pom nws daim ntawv thov nyob rau hauv kev tsim cov khoom uas yuav tsum muaj ib tug siab zog thiab corrosion kuj. Cov no suav nrog cov nkoj, cov tank thiab cov kav dej. Kev siv cov txheej txheem fiberglass yog tsim nyog nyob rau hauv ntau qhov chaw ntawm tib neeg kev ua ub no, txij li thaum nws nce lub insulating yam ntxwv ntawm cov qauv thiab qhov chaw, guarantees txhim khu kev qha sealing ntawm technical containers.

Linen fiberglass fabrics

Cov qauv fiberglass ntaub muaj fibers uas intertwine ntawm txhua qhov kev sib tshuam ntawm weft thiab warp. Kev sib tshuam ntawm cov xov yog nqa tawm ntawm lub kaum sab xis ntawm 90 ° thiab zoo li chessboard. Cov ntaub fiberglass no suav hais tias yog qhov ruaj khov tshaj plaws, tawv thiab ntom. Vim li no, lawv tau pom lawv daim ntawv thov nyob rau hauv qhov kev txhawb zog ntawm qhov tshwj xeeb loaded. Txawm li cas los xij, ntawm qhov tod tes, cov khoom siv no yog txwv tsis pub siv rau lub hom phiaj ntawm kev txhawb nqa thaj chaw ntawm cov duab nyuaj, vim nws tsis khoov thiab ncab zoo. Hom kev weaving no yog raug rau cov qauv fiberglass T 13 thiab T 23.

Fiberglass twill npuag

Lawv yog tsim los ntawm cov fibers uas sib cuam tshuam hauv txoj kev tshwj xeeb. Lub weft threads hla lub warp threads los ntawm ib tug. Nyob rau saum npoo ntawm cov ntaub, ib tug qauv ntawm kab pheeb ces kaum ntawm lub kaum sab xis ntawm 45 ° yog pom meej meej, uas tshwm sim vim kev hloov ntawm kev sib tshuam ntawm warp thiab weft threads. Lub ntsiab yam ntxwv ntawm cov qauv fiberglass fabrics yog siab plasticity, piv nrog cov ntaub ntawv weaving dawb. Lawv muaj qhov tsawg kawg nkaus ceev thiab siab tshaj plaws stretching peev xwm. Twill iav ntaub tuaj yeem siv rau kev txhawb nqa lub hom phiaj. Lawv yooj yim siv thaum tsim cov qauv ntawm cov kev teeb tsa nyuaj, nrog khoov, ledges thiab fab.

Satin fiberglass fabrics

Hom no yog tsim ua tsaug rau cov xoob xoob ntawm fibers. Ntxiv mus, nyob rau ib sab muaj ntau weft threads, nyob rau lwm yam - warp threads. Yog tias koj saib ze, koj tuaj yeem pom kab kab kab kab kab uas khiav ntawm lub kaum sab xis uas txawv ntawm tus qauv 45 ° lub kaum sab xis rau twill weave. Xws li cov ntaub yog tus cwj pwm los ntawm kev ua kom yooj yim ntawm qhov ntom ntom. Nws yog ib qho tsim nyog los xaiv lawv yog tias nws tau npaj los tsim cov khoom ntawm kev teeb tsa nyuaj.

hom kev weave no suav nrog T 11 qib ntawm cov qauv fiberglass.
