Generally high-quality Fiberglass sculptures are suitable for epoxy resin. The thickness of the standard epoxy resin table Li Gang sculpture is calculated based on theoretical values. Take three cloths and five coatings as an example. The thickness of each layer of glass fiber cloth is about 0.18mm-0.2mm. Each layer of resin The dry film thickness is about 80-100 μm, that is, 0.08 mm-0.1 mm.
Except for the primer and the topcoat, all other “three coatings” are immersed in fiberglass cloth, that is, the thickness is calculated based on the thickness of three layers of fiberglass cloth. According to this, the thickness of three cloths and five coatings is: 0.18 × 3 + 0.08 × 2 = 0.7mm to 0.2 × 3 + 0.1 × 2 = 0.8mm.
In order to obtain the actual measured thickness values, we selected five models from different construction sites: two cloths and four coatings, three cloths and five coatings, five cloths and seven coatings, six cloths and eight coatings, and seven cloths and nine coatings. The actual measured thickness is consistent with the theoretical value.
The conclusion is the corresponding relationship in the case of using 0.18-0.2mm glass fiber cloth. When the thickness of the Fiberglass sculpture is required, in practice, the thickness of the anticorrosive layer can be increased by using thicker glass fiber cloth, glass fiber felt, or adding one or more resin cements.
