Yuav ua li cas fiberglass nto mats optimize molding thiab zoo ntawm FRP khoom?
Fiberglass nto levyog ib qho kev hloov kho rau cov khoom siv fiberglass xws li tws strand lev (CSH) thiab woven grating, raws li cov xwm txheej tam sim no ntawm cov khoom tiav. Thaum cov pa CSH tuaj yeem muaj li ntawm 100g mus rau 900g lub hauv paus hnyav, cov lev saum npoo ua tiav nws nrog cov nplua, luv fibers, uas ua rau txawm tias qis dua qhov hnyav thiab thinner thickness, tsawg li 20g. Nws yog feem ntau tsim nyob rau hauv qhov hnyav ntawm 20g mus rau 100g, hais txog qhov tsis txaus ntawm CSH hauv qee daim ntawv thov. Vim tias cov lev saum npoo zoo txhim kho cov tsos zoo ntawm FRP cov khoom, nws feem ntau siv ua ke nrog lwm cov khoom siv fiber ntau rau siab -requirement FRP khoom.
Nto lev nta cov khoom siv fiber ntau, lub ntsej muag du thiab tiaj tus, tiv thaiv corrosion, cov ntsiab lus tsis tshua muaj nplaum, thiab cov txheej txheem zoo, ua rau nws nrhiav tau los ntawm cov neeg siv khoom hauv tsev thiab txawv teb chaws.
Cov txheej txheem tsim tshwj xeeb ntawm cov lev saum npoo ua rau lub ntsej muag du, cov fiber ntau dispersion, zoo txhais tes, breathability siab, muaj zog adhesion, thiab cov resin impregnation ceev. Cov mats nto yog siv hauv cov khoom fiberglass. Lawv zoo heev breathability tso cai rau cov resin nkag mus sai, tshem tawm cov npuas thiab dawb stains. Lawv zoo moldability ua rau lawv haum rau qhov chaw ntawm cov khoom thiab molded qhov chaw nrog ib tug complex duab. Lawv tuaj yeem zais cov ntaub textures, txhim kho qhov smoothness thiab leak-proofness, thaum tib lub sij hawm txhim kho interlaminar shear zog thiab deg toughness, txhim kho cov khoom corrosion kuj thiab huab cua tsis kam. Lawv yog qhov tseem ceeb rau kev tsim cov khoom zoo - fiberglass pwm thiab cov khoom. Haum rau fiberglass tes nteg-up molding.
