Ua ntej tshaj plaws, koj yuav tsum paub tias cov kev cai tshwj xeeb ntawm cov pwm yog dab tsi, ib txwm muaj, tiv taus kub siab, tso tes, lossis cov txheej txheem nqus tsev, puas muaj cov kev cai tshwj xeeb rau qhov hnyav lossis kev ua tau zoo?
Nws yog ib qho tseeb tias lub zog sib xyaw thiab tus nqi ntawm cov ntaub iav fiber ntau thiab polyester resins kuj txawv. Peb yuav tsum paub ntau ntxiv kom ntseeg tau tias muaj kev sib xyaw ua ke ntawm cov khoom siv pwm uas xav tau thiab ua kom cov nqi tsim pwm zoo dua.
Hauv kev hais yooj yim, cov pwm siv rau cov txheej txheem tso tes ntawm FRP yog qhov feem ntau. Raws li kev tswj hwm tus nqi qis tshaj plaws, nws yog qhov tseeb tias hauv ntau qhov xwm txheej, tsuav yog FRP pwm ua tau raws li qhov xav tau tiag tiag, kev ua tau zoo dua txhais tau tias tus nqi siab dua.
Qee cov ntaub ntawv tsim nyog rau kev ua pwm FRP ib txwm muaj, koj tuaj yeem nkag siab dav dav:
| Hom | Kev txhawb nqa Fberglass | Cov roj hmab | Cov khoom siv ntxiv |
| Tes Lay-up FRP Mould | 300g hmoov txiav strand lev, 30g nto lev, 400g gingham, bulked xov (R ces kaum filling hloov pauv) | txheej vinyl gel, cov resin tsis muaj roj, cov resin vinyl, cov resin tshiab xoom shrinkage | Silica, tshuaj pleev pwm, pva, tshuaj kho, tshuaj pleev polishing, ntawv xuab zeb |
| Epoxy resin pwm | 300g hmoov txiav strand lev, 30g nto lev, 400g gingham, bulked xov (R ces kaum filling hloov pauv) | Epoxy gel txheej, epoxy resin (ntau yam kub tsis kam) | Tso cov quav ciab, pva, tus neeg sawv cev kho, quav ciab polishing, ntawv xuab zeb |
| Pwm nqus tsev | 300g hmoov txiav strand lev, 30g nto lev, 400g gingham, bulked xov (R ces kaum filling hloov pauv) | polyester cob | Silica, tshuaj pleev pwm, PVA, tshuaj kho, tshuaj pleev polishing, ntawv xuab zeb, roj silicone |
| RTM FRP pwm | 300g hmoov txiav xov lev, 30g nto lev, 400g gingham, xov bulked (R lub kaum sab xis filling hloov pauv), lev muaj zog | polyester cob | Silica, cov quav ciab flakes, quav ciab tso pwm, pva, tus neeg sawv cev kho, quav ciab polishing, ntawv xuab zeb |
Hauv kev tsim pwm tiag tiag, yuav muaj ntau cov khoom siv pwm koom nrog, xws li putty, gel txheej yooj yim rau polish, thiab lwm yam khoom siv hloov kho qhov chaw rau pwm qub.
