我上次去呢頭只係見過藍 foam, 幾十蚊買左塊。但見唔到紅 foam 同綠 foam﹐雖然呢幾隻 foam 都係同樣材料﹐只係牌子唔同﹐但有多D選擇都好。可否相告確實地址同舖名 ?

| 又係ｚｍａｎ提供：ｐｉｎｋ ｆｏａｍ 在灣仔聖備買、４ｘ８尺約１２０元、聖備資料可在黃頁軟木發泡找、但ｐｉｎｋ ｆｏａｍ比ｂｌｕｅ／ｇｒｅｅｎ ｆｏａｍ重，約為１０－２５巴仙、而在旺角買的ｆｏａｍ係用作天台地台隔熱用，所以ｆｏａｍ邊起級、方便互疊再落防水及英泥、ｂｌｕｅ ｆｏａｍ比較快變粉碎，可能硬，ｇｒｅｅｎ ｆｏａｍ耐用，可能ｕｎ、當然唔同廠出品又有分別、未知有冇師兄提供詳細學名及分別、另上次買ｇｒｅｅｎ ｆｏａｍ的舖名唔記得、地址約在廣東道豪戲院向前行、到小露天車場對面、恒通大地下碧文天花材料隔離鋪、係賣防水防火化工料、ｇｒｅｅｎ ｆｏａｍ會鋪內架頂、ｇｏｏｄ ｌｕｃｋ！

呢 D 發泡膠材料既化學成份同書局賣既白色發泡膠一樣﹐叫 Expanded PolyStyrene﹐簡稱 EPS。呢D發泡膠有幾隻色﹕綠﹐紅﹐藍﹐灰﹐黃。唔同顏色只係代表唔同生產商﹐每隻顏色都有唔同硬度同重量供選擇。所以無話邊隻色特別重或硬。 綠 foam 係 BASF 化工生產﹕ http://www.basf.de/basf/html/plastics/englisch/pages/schaum/styrodur.htm 藍 foam 係 DOW 化工生產﹕ http://www.dow.com/styrofoam/index.htm 紅 foam 係 Owen Corning 化工生產﹕ http://owenscorning.com/around/insulation/products/foamular.asp |

勁抽﹗老兄應該係全港頭幾個人做呢種結構既 DIY 機。記住貼多D相上黎俾大家睇。我試過 bag 塊 balsa 做實驗, 想D纖維布係後緣出面黐埋﹐但咁簡單既野都失敗﹐所以我仲未敢 bag foam 翼。

我諗住用pink foam做core, 加carbon rods做support, 一塊fiberglass cloth+epoxy, 再加多層Microballon+epoxy做finishing. 不過都有好多小問題要解決. e.g. 上epoxy去fiber cloth時成日都會黐唔實塊pink foam, D鬼老用heater去solve呢個問題, 但無啦啦去邊度搵咁大個heater呀! 不過係try and error既過程會學到好多野, 失敗得返黎既經驗會比成功多. 有機會大家一齊研究下啦! Vacumm bag我都未識整, 同埋D架餐(Mylar, pump, heater, ...)都唔知去邊搵. 遲D真係要請教下你! |

Henry 講既 heater 會唔會係指一般鬼佬叫既 hot box﹐ thermal box 或 curing box ﹖ 對室溫硬化既 epoxy 黎講﹐ 佢既作用係加快硬化時間﹐epoxy 一般每加熱 10 度﹐硬化時間就減半。我都用紙盒粗粗地整左個。幾好用。如果係做真空袋﹐加熱D epoxy 仲可以令D膠稀D, 加強流動性﹐可以令多餘既膠容易D?#24517;?#36208;﹐有助減輕製成品重量。

Fiberglass coated on the wings, but not very good! You can see that the cloth can't stick onto the foam firmly.

Actually this is not a good method compare with bagging, but as an experiment it's worth to try I think. Eventually, I'll make a bagged version. |

DIY 既滿足感係來自發現自己都可以做到﹐有時仲係用自己唸出黎既方法﹐唔駛跟人地﹐好﹗努力﹗加油﹗支持﹗ |
