Dab tsi yog qhov sib txawv thiab kev siv ntawm chopped strand lev thiab nruam fiberglass lev?
I. Fiberglass Chop Strand Mat: High Uniformity, Ntau Saj Moulding
Fiberglass tws strand lev yog ib daim ntawv lev ua los ntawm kev txiav cov iav fiber ntau rau hauv qhov ntev, faib lawv sib npaug yam tsis muaj kev taw qhia, thiab tom qab ntawd khi lawv nrog hmoov lossis emulsion binders.
Nws cov yam ntxwv tseem ceeb yog qhov tseem ceeb heev: isotropy, txhais tau hais tias nws cov khoom siv kho tshuab yog qhov zoo ib yam nyob rau hauv ob qho tib si transverse thiab longitudinal cov lus qhia. Thaum lub sij hawm molding, nws muaj qhov ua tau zoo heev rau qhov chaw nkhaus thiab cov qauv tsis sib xws, thiab nws tsis tshua muaj qhov wrinkling thiab blistering.
Nyob rau tib lub sijhawm, nws muaj qhov ceev ceev impregnation, kev sib raug zoo nrog cov cob, thiab kev tsim kho siab.
Txawm li cas los xij, kuj hais lus, qhov ntev fiber ntau ntawm tws strand lev yog txwv, thiab nws tag nrho tensile lub zog thiab qaug zog kev ua tau zoo tsis muaj zog tshaj li niaj zaus lev, ua rau nws tsim nyog rau cov xwm txheej uas yuav tsum tau muaj zog me ntsis thiab siab molding complexity.
II. Fiberglass Nruam Mat: Lub zog siab tshaj plaws, txhim khu kev qha ntau dua -Cov kabmob muaj peev xwm
Nruam lev yog ua los ntawm nruam iav fiber ntau roving, nteg thiab sib koom ua ke nyob rau hauv ib tug kauv los yog oriented yam, tswj fiber ntau txuas ntxiv.
Nws qhov txiaj ntsig loj tshaj plaws nyob hauv nws cov khoom siv kho tshuab zoo tshaj. Nws lub zog tensile, qaug zog tsis kam, thiab kev ruaj ntseg ntawm cov qauv yog qhov zoo tshaj plaws rau kev sib tw strand lev, ua rau nws tuaj yeem tiv taus ntau dua thiab ua haujlwm ntev dua, ua rau nws tshwj xeeb tshaj yog haum rau cov khoom tseem ceeb nrog cov txheej txheem nruj zog.
Txawm li cas los xij, kev xav tsis tu ncua nthuav tawm ntau tshaj tawm anisotropy, ua rau nws yooj yim me ntsis hloov mus rau txoj kab nkhaus nkhaus dua li chopped strand lev. Nws lub impregnation ceev kuj tseem qeeb, ua rau nws tsim nyog rau fabricating li niaj zaus, siab - lub zog structural Cheebtsam.
Nyob rau hauv luv luv: Xaiv tws strand lev rau saj zawg zog txoj kev, thiab nruam xav rau qhov kawg lub zog.
III. Qhov tseem ceeb sib txawv ntawm ib saib
Los ntawm cov txheej txheem tsim khoom thiab cov yam ntxwv ua tau zoo rau daim ntawv thov scenarios, qhov sib txawv ntawm ob yog pom meej:
1. Fiber State: Chopped strand lev tau randomly faib luv luv tws fibers, thaum nruam lev muaj nruam filaments teem nyob rau hauv ib tug oriented / helical qauv;
2. Mechanical Properties: Chopped strand lev yog isotropic thiab muaj zog nruab nrab, thaum nruam lev muaj zog thiab tseem ceeb anisotropy;
3. Formability: Chopped strand lev muaj zog adhesion thiab yog haum rau irregularly zoo li tus, thaum nruam lev yog tsim nyog rau lub tiaj / tsis tu ncua structural qhov chaw;
4. Impregnation Efficiency: Chopped strand lev impregnates nrog resin sai, thaum nruam lev impregnates ntawm tus nqi qis dua;
5. Tus nqi ntau: Nyob rau tib lub hauv paus hnyav, cov nqi tsim khoom ntawm cov lev txuas ntxiv yog me ntsis siab dua li ntawm cov ntaub qhwv strand.
IV. Precise Application Scenarios: Xaiv cov khoom zoo ua rau txhua qhov sib txawv
Raws li kev lag luam xav tau tiag tiag, daim ntawv thov scenarios rau ob hom fiberglass lev yog segmented heev:
Daim ntawv thov cheeb tsam ntawm Fiberglass Chopped Ncaj Strand Mat
- Cov khoom siv hauv chav da dej: cov dab da dej, cov tais da dej, cov tais ntxhua khaub ncaws, thiab lwm yam khoom siv fiberglass tsis zoo, muab siab haum thiab du;
- Fiberglass Corrosion Protection: Cia tank, pipelines, anti-corrosion flooring, muab kev tiv thaiv corrosion thiab yooj yim siv;
- Automotive Accessories: Lub cev vaj huam sib luag, qhov chaw sab hauv, fairings, ntsuas lub teeb yuag tsim thiab formability;
- Cov khoom me me thiab nruab nrab- cov khoom siv fiberglass loj, ua pwm, thiab dav dav - lub hom phiaj txhawb cov qauv tsim.
Daim ntawv thov thaj chaw ntawm Fiberglass Nruam Mat
- Tshiab Zog Cua Turbine Hniav: Hniav lub ntsiab qauv, lub ntsiab nqaj, thiab lwm yam tseem ceeb load-cov kabmob, yuav tsum muaj lub zog siab thiab qaug zog;
- Lub nkoj loj fiberglass hulls, cov hlab ntsha siab, thiab lub zog cua - ntsig txog cov khoom siv;
- Muaj cov qauv kev txhim kho nrog cov khoom hnyav heev -cov kabmob thiab cov kav ntev.
Raws li tuaj yeem pom, cov haujlwm tseem ceeb xws li lub zog tshiab cua turbine hniav, cov khoom siv huv, kev tiv thaiv fiberglass corrosion, thiab cov khoom siv hauv tsheb txhua tus cia siab rau kev sib xyaw ua ke ntawm ob hom fiberglass lev. Kev xaiv cov khoom ncaj qha txiav txim siab cov khoom zoo thiab lub neej ntev.
V. Cov Lus Qhia Xaiv Cov Khoom Siv: Tsis txhob muaj kev xav tsis zoo
1. Tsis txhob dig muag mus nrhiav lub zog siab: yuam cov mats txuas ntxiv mus rau qhov nyuaj, qhov tsis sib xws tuaj yeem yooj yim ua rau tsis zoo adhesion thiab nkim nqi.
2. Tsis txhob siv tws strand lev los hloov cov core load-cov khoom siv bearing: Txwv tsis pub, tawg, deformation, thiab luv luv lifespan yuav tshwm sim.
3. Xav txog cov txheej txheem resin: Cov kev cai rau kev xaiv cov khoom sib txawv me ntsis nyob ntawm seb nws yog epoxy resin los yog unsaturated polyester resin.
4. Ua ntej tshaj plaws cov tuam txhab muaj npe nrov: Cov ris tsho hauv qab hnyav thiab ruaj khov adhesives ncaj qha txhim kho cov khoom tiav tiav.
Hauv kev lag luam niaj hnub no tau tsim cov ntaub ntawv sib xyaw ua ke, cov kev xav tau rau cov ntaub ntawv fiberglass hauv cov teb xws li lub zog tshiab cua turbine hniav, cov khoom siv tu cev, fiberglass corrosion tiv thaiv, thiab cov khoom siv hauv tsheb tau nce zuj zus. Txawm tias qhov sib txawv me me hauv kev xaiv cov khoom siv tuaj yeem ua rau cov khoom sib txawv kiag li. Tsis muaj qhov zoo lossis qhov tsis zoo ntawm cov hlua khi thiab cov lev txuas ntxiv; nws yog txhua yam hais txog compatibility. Tsuas yog los ntawm kev paub meej qhov txawv ntawm ob qho tib si thiab sib piv nrog lawv tus kheej cov khoom xav tau tuaj yeem ua tiav cov khoom tsim tau zoo, kev hloov kho kom zoo, thiab cov nqi zoo.
