Kev piav qhia ntxaws ntawm Cov Qauv, Kev Sib Sau, thiab Cov Lus Qhia Ntawm Fiberglass Surface Mat

Fiberglass nto lev yog ib qho ultra-thin nonwoven khoom ua los ntawm alkali-dawbfiberglasssiv cov txheej txheem ntub dej -forming (papermaking). Txawm hais tias tsis yog ib qho kev thauj khoom tseem ceeb- cov qauv kev coj tus kheej, nws ua zoo li "qhov ncauj qhov ntswg," uas npog cov txheej txheem sab nraud ntawm cov khoom. Nws seals textures, tiv thaiv huab cua npuas, txhim kho smoothness, thiab tsub kom toughness, ua rau nws ib tug indispensable deg reinforcement cov ntaub ntawv rau siab -kawg composite cov ntaub ntawv.

Los ntawm kev pom sab hauv cov qauv, cov lev saum npoo nthuav tawm peb qhov -dimensional, random, thiab uniform network faib. Cov fibers yog randomly interwoven, nrog nruab nrab tej thiab ib tug tsim nyog porosity. Cov qauv no tso cai rau kom nrawm thiab tsis sib xws resin impregnation, tshem tawm cov pa npuas sai sai thiab ua kom tuab, du, resin- nplua nuj txheej tom qab molding. Qhov no tseem ceeb tiv thaiv tsis xws luag xws li nthuav tawm fiberglass weave, nto pitting, thiab pinholes. Nyob rau tib lub sijhawm, cov qauv sib xyaw ua ke txhim kho qhov cuam tshuam tsis kam thiab interlayer kev sib txuas ntawm cov txheej txheem saum npoo, ua rau cov khoom ruaj khov, tsis tshua muaj kev tawg, thiab tsis tshua muaj kev cuam tshuam rau delamination.

Tam sim no cia peb saib cov ntsiab lus tseem ceeb. Mainstream nto mats feem ntau siv E- iav (alkali-dawb iav fiber ntau), uas boasts qhov zoo xws li rwb thaiv tsev zoo, siab zog, dej thiab acid / alkali tsis kam, thiab dimension stability, ua rau nws haum rau siab - kawg daim ntaub ntawv nyob rau hauv cua zog, huv si ware, electronics, thiab automotive industries. Nruab nrab-alkali iav fiber ntau kuj tseem siv rau hauv qee qhov kev siv dav dav rau cov nqi zoo dua-kev ua tau zoo. Cov fiber ntau monofilament txoj kab uas hla yog feem ntau 6-13μm, thiab qhov ntev yog tswj ntawm 6-25mm kom ntseeg tau tias muaj kev cuam tshuam thiab molding nyhuv. Adhesives feem ntau yog polyester, acrylic, los yog hloov kho epoxy systems, qhia tau zoo heev compatibility nrog unsaturated resins, vinyl esters, thiab epoxy resins, kom muaj zog adhesion, tsis muaj hmoov, thiab tsis delamination.

Tom ntej no yog cov kev qhia tshwj xeeb uas kev lag luam muaj kev txhawj xeeb tshaj plaws, raws li lawv ncaj qha txiav txim siab qhov ua tau zoo thiab tus nqi:

- Qhov hnyav: Cov qauv loj yog 20g/㎡, 30g/㎡, 40g/㎡, thiab 50g/㎡. Lub hauv paus hnyav hnyav yog haum rau siab - qhov ua kom pom tseeb qhov tseeb, thaum lub hauv paus hnyav hnyav yog qhov tsim nyog rau kev tiv thaiv muaj zog thiab siab tawv.

- Dav: Feem ntau siv yog 1000mm thiab 1250mm, tab sis kev cai dav muaj nyob rau ntawm kev thov.

- Thickness: Feem ntau 0.15-0.30mm, ultra-nyias thiab sib xws, sib xws rau qhov hnyav.

- Tensile Strength: Ntau dua lossis sib npaug li 25N / 50mm (ntev), siab - cov khoom zoo tuaj yeem ncav cuag 40N.

- Fiberglass Cov ntsiab lus: 8% -15%, ntsuas impregnation ceev thiab molding stability.

- Cov txheej txheem siv tau: Tes nteg- nce, txau, nqus casting, molding, kub nias, thiab lwm yam.

Qhov tsis raug tsis raug tuaj yeem ua rau muaj qhov sib txawv kaum npaug ntawm kev ua haujlwm. Feem ntau hais lus: 30g / ㎡ yog tus qauv universal haum rau feem ntau cov khoom fiberglass; 50g / ㎡ yog haum rau cov ntawv thov uas yuav tsum tau muaj zog dua thiab flatness; ultra-nyias 20g/㎡ feem ntau yog siv rau hauv cov khoom siv hluav taws xob precision thiab me me nkhaus.

Daim ntawv thov ntawm fiberglass nto mats tau ntev npog txhua yam ntawm lub neej: chav dej fixtures, yacht hulls, cua turbine hniav, tshiab zog tsheb casings, pipeline corrosion tiv thaiv, tsheb qhov chaw, thiab tam sim no nrov neeg siv electronics casings.

High-cov xov tooj kawg thiab cov khoom siv ntse siv tau siv fiberglass nto lev kom ua tiav qhov nyias nyias, siab zog, siab flatness, thiab teeb liab- ua haujlwm zoo. It has low density and high strength, is lighter than metal and stronger than ordinary plastic; nws tsis thaiv 5G cov cim qhia thiab tsis cuam tshuam rau kev them nyiaj wireless; Tom qab molding, qhov saum npoo yog du thiab textureless, thiab tuaj yeem ua rau matte, textured, thiab xim xim, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov xov tooj.

Rau cov chaw tsim khoom, xaiv qhov zoo saum npoo lev tuaj yeem txhim kho cov txiaj ntsig zoo, txo cov nqi rov ua haujlwm, thiab txhim kho cov khoom zoo. High- zoo nto lev muaj plaub qhov zoo: zoo li fiber ntau dispersion tsis clumping, tshem tawm qhov tsis xws luag; ceev resin impregnation, txhim kho ntau lawm efficiency; zoo heev moldability, zoo kawg nkaus haum txawm complex nkhaus nto; thiab huab cua thiab corrosion kuj, ncua cov khoom lifespan.
