Fiberglass Material Application Guide
Muaj ntau txoj hauv kev los faib cov iav fiberglass Ib txoj hauv kev, raws li cov khoom siv hauv iav, yog faib cov iav fiberglass rau hauv alkali-dawb fiberglass (E iav), nruab nrab-alkali fiberglass (C iav), siab -alkali fiberglass (A iav), alkali- iav fiberglass ({ AR4}). Tam sim no, tsuas yog alkali-dawb fiberglass yog tsim rau tsim fiberglass nuv ntses nkoj. Cov no suav nrog alkali-dawb fiberglass nto lev, alkali-dawb fiberglass woven fabrics, alkali-dawb fiberglass tws strand lev, thiab alkali-dawb fiberglass multi-axial fabrics/composite fabrics. Hauv qab no yog cov lus qhia luv luv rau E, C, thiab A hom fiberglass.
I.Alkali-Dawb Fiberglass(E iav)
Alkali-dawb fiberglass yog hais txog aluminoborosilicate fiberglass nrog alkali hlau oxide (Na₂O thiab K₂O) cov ntsiab lus tsawg dua 0.8%. Nws muaj kev ruaj ntseg zoo heev, hluav taws xob rwb thaiv tsev, thiab lub zog. Tam sim no, tshaj 90% ntawm cov iav fibers siv thoob ntiaj teb yog E iav muaj pes tsawg leeg. Raws li "Specifications for Construction of Fiber-Reinforced Plastics for Fishing Boats," txhua lub nkoj fiberglass yuav tsum siv alkali-dawb fiberglass.
Tam sim no, cov tuam txhab loj- nplai fiberglass tseem tab tom tshawb nrhiav thiab tsim cov hom tshiab ntawm alkali-dawb iav fibers los txhim kho fiber ntau lub zog, modulus, thiab tshuaj tiv thaiv, thaum tib lub sijhawm ua iav fiber ntau ntau zog- ua haujlwm zoo thiab ib puag ncig zoo, thiab txo cov nqi tsim khoom.
II. Nruab nrab-Alkali iav Fiber (C iav)
Nruab nrab-alkali iav hais txog dej qab zib- cov iav silicate iav nrog alkali hlau oxide cov ntsiab lus xws li 10% mus rau 13%. Nws cov yam ntxwv suav nrog cov tshuaj tiv thaiv zoo tshaj plaws, tshwj xeeb tshaj yog cov tshuaj tiv thaiv acid, piv rau alkali - iav dawb, tab sis cov khoom siv hluav taws xob tsis zoo thiab cov khoom siv hluav taws xob qis dua li alkali - iav fiber ntau.
Feem ntau, cov khoom nruab nrab tuaj txawv teb chaws -alkali fiberglass muaj qee qhov nyiaj ntawm boron trioxide, thaum Suav nruab nrab -alkali fiberglass yog boron tag nrho - dawb. Txawv teb chaws, nruab nrab-alkali fiberglass tsuas yog siv los tsim cov khoom siv corrosion-cov khoom siv fiberglass, xws li fiberglass nto mats, thiab tseem los txhawb cov ntaub ntawv asphalt vov tsev. Txawm li cas los xij, hauv Suav teb, nruab nrab -alkali fiberglass tseem tuav ib qho kev lag luam sib koom, siv los txhawb fiberglass thiab hauv kev tsim cov lim ntaub thiab cov ntaub qhwv. Tau ntev, nws tau sib tw vim nws tus nqi qis dua piv rau alkali -dawb fiberglass. Txawm li cas los xij, nrog kev siv thev naus laus zis tsis tu ncua thiab txo tus nqi hauv ultra-loj- nplai alkali- cov cub tawg dawb, nruab nrab-alkali iav fiber ntau tsis muaj qhov zoo dua.
Nyob rau hauv lub neej yav tom ntej, kev ua lag luam sib faib ntawm cov khoom uas tsim los ntawm outdated crucible kos duab txoj kev xws li nruab nrab -alkali fiberglass yuav maj mam txo thiab tej zaum yuav txawm raug tshem tawm.
III. Siab -alkali iav Fiber (Ib iav)
High-alkali fiberglass muaj Na₂O thiab K₂O cov ntsiab lus ntau dua 14.0%. Nws yog feem ntau kos los ntawm cov ntaub ntawv raw xws li crushed ca iav thiab crushed lub raj mis iav thiab siv tau raws li roj teeb cais, yeeb nkab wrapping fabrics, thiab muaj ntaub ntawv. Kev tsim kub ntawm siab -alkali fiberglass yog qis dua li ntawm alkali-dawb thiab nruab nrab-alkali iav. Qee cov tuam txhab lag luam me siv tsis yog-platinum spinnerets nrog siab -alkali iav formulations los tsim cov khoom qis{10}} kawg. High-alkali fiberglass yog qhov ua tau rau dej thiab atmospheric noo noo yaig. Nyob rau hauv huab cua ntub, nws sai sai ua nkig, poob lub zog, thiab yuav siv tsis tau. Tam sim no, siab -alkali fiberglass tsis tshua tsim.
Lub teb chaws tau txwv tsis pub tshaj tawm cov khoom siv hluav taws xob siab -alkali fiberglass thaum ntxov li xyoo 1980s, tab sis qee qhov chaw me me tseem ua tsis raug cai, txawm tias nws sib xyaw nrog alkali-dawb fiberglass kom dhau nws li siab - zoo. Yog li ntawd, txhua lub nkoj nuv ntses fiberglass yuav tsum yuav cov khoom lag luam los ntawm cov chaw tsim khoom muaj npe thiab tsis txhob cuam tshuam kev nyab xeeb los ntawm kev yuav cov nkoj nuv ntses fiberglass uas ua rau muaj kev phom sij!
