环氧树脂计算器
本环氧树脂计算器精确计算所需的树脂和固化剂用量。输入表面的长度、宽度和深度(英寸),选择混合比例(1:1、2:1 或 3:1),获取总液体盎司数以及树脂和固化剂的分量。12×12 英寸、⅛ 英寸深的浇注约需 9.97 液体盎司混合环氧树脂。

常见问题
环氧树脂计算器是如何工作的?
环氧树脂计算器根据项目的长、宽、深尺寸计算所需树脂量。公式为:体积 = 长 × 宽 × 深。然后根据树脂与固化剂的混合比例(通常为 1:1 或 2:1)计算各组分的用量。
覆盖用量和填充用量有什么区别?
覆盖用量(涂层型)适用于桌面保护层,通常每次浇注 1/8 英寸(3mm)厚;填充用量适用于深度浇注(如河流桌、模具浇注),可一次浇注更厚。需选择对应的产品类型。
为什么混合比例很重要?
环氧树脂的混合比例(A 组分树脂与 B 组分固化剂)必须精确,偏差会导致固化不完全——表面发粘、强度不足或完全不固化。请按产品说明书严格遵守重量比(更精确)或体积比。
环氧树脂每平方英尺/米的用量是多少?
薄涂层(约 1/16 英寸,1.6mm)每平方英尺约需 0.13 加仑(约 0.5 升);厚度加倍则用量加倍。本计算器会根据您输入的具体深度精确计算用量。
Epoxy Resin Formula
To calculate how much epoxy resin you need, multiply the surface dimensions to get cubic inches, then convert to fluid ounces using the density of cured epoxy (≈ 0.554 fl oz per cubic inch).
Volume (in³) = Length × Width × Depth
Total oz = Volume × 0.554
Resin oz = Total oz × (R / (R + H))
where R:H is the mix ratio (e.g., 2:1 means R=2, H=1)
Mix Ratio Guide
| Ratio | Common Use | Resin % |
|---|---|---|
| 1:1 | Table tops, art resin, casting | 50% |
| 2:1 | Marine, structural, boat building | 67% |
| 3:1 | Fiberglass laminating, some casting resins | 75% |
Always check your specific resin product's data sheet. Incorrect ratios prevent proper curing.
Tips for Epoxy Projects
- Add 10–15% extra — Account for mixing losses, drips, and surface irregularities.
- Temperature matters — Epoxy cures faster in warm conditions. Most resins require 70–80°F (21–27°C) for proper cure.
- Pour in layers — For depths over ¼ inch, pour in multiple ¼-inch layers to prevent exothermic cracking.
- Mix thoroughly — Scrape the sides and bottom of the container. Undermixed resin stays sticky permanently.
- Pot life vs. cure time — Pot life (working time) is 20–45 min for most resins. Full cure takes 24–72 hours.
