Raw cov ntaub ntawv rau fiberglass nruam raj wrapping

Cov ntaub ntawv siv zog: Raws li kev tsim cov kav dej FRP thiab PVC / FRP cov kav dej sib xyaw, cov khoom siv txhawb nqa muaj xws li cov ntaub ntawv saum npoo, tws fiberglass lev lossis rab koob-punched composite muaj kev sib xyaw ua ke nrog kev xav, thiab tsis muaj kev sib tw.
Resin matrix: Cov resin siv rau cov yeeb nkab txuas txuas ntxiv yog feem ntau unsaturated polyester cob. Cov kev xav tau ntawm cov resin nyob rau hauv cov txheej txheem txuas txuas txuas yog: tsim nyog viscosity, yooj yim nkag mus rau hauv cov fiber ntau, lub sij hawm ntev gel, luv curing lub sij hawm, tsawg curing exotherm, thiab me me curing shrinkage.

Cov ntaub ntawv pabcuam: Txhawm rau txhim kho qhov tawv ntawm cov yeeb nkab, quartz xuab zeb feem ntau ntxiv, thiab cov nyiaj ntxiv tuaj yeem ncav cuag 30% (qhov siab tshaj). Siv cov yeeb yaj kiab polyester ua tus neeg sawv cev tso tawm. Txiav cov zaj duab xis rau hauv ib daim hlab, qhov dav yog ob npaug ntawm qhov dav ntawm cov hlau sawb, thiab qhwv thiab sib tshooj 1/2.
