Step 1: get ready for work.

 

First according to the shipping lines, size of steel or wood dies, the mold surface treatment must ensure to have high hardness and high gloss, and the mold edge to keep at least 15 cm, is advantageous for the sealing strip and the laying of pipeline.

After cleaning the molds, apply the stripping material, and can be dewaxed or wiped out.

 

Step 2: apply the hull gel.

 

According to the requirements of ship's production within the mold surface coating gel coat resin containing catalyst/delivering agent, can use the product gel or burnish gel, choose type between adjacent benzene, benzene and vinyl.

Hand brush and spray painting method can be used for construction.

 

Step 3: apply reinforcement.

 

According to the hull lines and basic structure, the reinforced material and skeleton core material are respectively made, and then laid in the mold according to the layer drawing and molding process.

The effect of material and connection mode on resin velocity must be fully considered.

 

Step 4: apply vacuum and auxiliary materials.

 

In the mould, the reinforced material is laid out, then the cloth is laid out, then the guide cloth, and finally the vacuum bag, the seal strip is used for compacting and sealing.

Before closing the vacuum bag, consider the direction of resin and vacuum tube.

 

Step 5: remove the vacuum inside the bag.

 

After finish the laid of the above materials in mold, clamping piping on the resin imported into the tube, using vacuum pump to the whole system of pumping air into vacuum state, the system of air time, as far as possible and check the whole air tightness, to the place of leakage local repair.

 

Step 6: mix the resin ratio.

 

After the vacuum in the bag reaches a certain requirement, the resin, curing agent and other hosts should be proportioned according to the environmental conditions, the thickness of the products and the area of laying.

The prepared resin solution should be suitable for the suitable viscosity, suitable gel time and the expected curing degree.

 

Step 7: mold guide resin.

 

Guide the deployment of good resin pressure pump, by fully mixing rule out resin bubbles, again according to the order, guide people open clamp, and through continuous adjustment of pump pressure guide implementation of resin, to effectively control the thickness of the hull of the ship.

 

Step 8: solidify the stripping outfitting.

 

After the resin guide is completed, the hull shall be suspended in the mold for a period of time to allow the resin to solidify, generally not less than 24h, which can be removed after the hardness is greater than or equal to 40.

After stripping, the necessary measures should be taken to support and avoid deformation.

After thorough curing, the boat will be closed and outfitting.
