Brushing the gel coat glass steel sculpture
To be completely dry after the release agent, the special coating with brush two times of brushing, apply drama to uniform, until the first layer of initial setting after brushing second layer. Here we should pay attention to in gel cannot besmear too thick, to prevent surface crack and wrinkle. Gel coat layer thickness is 0.5~0.8mm. Gel is a kind of resin, the resin is very important in the production of glass steel products by hand, it can not only play a role of protective layer on glass surface, but also can play the surface decoration effect, as long as add in gel paste, the surface of the product will have a corresponding color. The glass and steel products use environment and do not require the same, so we must according to the actual situation of coating resin used in different varieties, the current grade: TM-33, TM-35, S-739, gel 33. You can use the brush to coat onto the mold cavity, can also use pneumatic spray gun than to the above, with the brush to evenly, the effect is good, there are generally used to spray the gel coat. The natural gel solidified generally need half an hour or so, can be used to speed up the curing time of the drying room, until the spray coat is dry, you can begin to paste resin and glass fiber.
Resin resin for glass sculpture; resin for making gum
First of all, and curing agent in a certain proportion of stirring evenly, in order to speed up the curing time of the product, unsaturated resin grades generally to 191, 196# resin used most widely. If you use epoxy resin. According to the viscosity of the resin at normal temperature, it can be properly preheated. And then 100 copies of WSP6101 type epoxy resin and 8-10 copies (mass ratio) of acetone (or propylene butyl ether) mixed in a clean container, stir, then add curing agent 20 ~ 25 (the amount of curing agent should be based on appropriate temperature field), rapid mixing, vacuum debubble 1min ~ 3min, to remove the resin liquid in the bubble, you can use.
Demoulding of glass fiber reinforced plastic sculptures
In the normal temperature (about 20 degrees Celsius) paste prepared sculpture, usually 48 hours basic curing stereotypes, that can be released. For a complete glass steel sculpture product, the subsequent process is still necessary. Some of the sculpture products after stripping, the surface is scratched or docking is not in place, which requires the use of the same brand of resin to glue and repair, after curing polished correction. If it is a sculpture of high finish, it is necessary to use 400# to 1200# water sand paper to polish the sculpture surface, and to polish the sculpture surface by polishing machine. Some sculpture edge is with other parts, need to guarantee the thickness, in the back of the product should be too thick place polished to achieve the required thickness. A lot of glass and steel sculpture products are needed by embedded metal parts and other products to install together, to embed these parts, first of all the products and sheet metal on a shelf is profiling (profiling, and products will be embedded in the metal sheet can be fixed in size to the relationship position), and then through the resin and glass fiber felt like paste products that put pieces of sheet metal embedded into the product. These processes will directly affect the quality of the product.
