Fibreglass Step Ladders , Cooling Tower Parts Non-slip FRP Stairway


Quick Detail:

The manufacturing process for FRP product consists of 7 processes: Raw materials preparation, Mold preparation, Hand paste molding, Solidify, Take off the mold, Disposal, Inspection (see the diagram as below). Each Technique has to be conducted according to the Operation Manuel.


Specifications:

Description:

1. Molding Condition:

To assure the quality of the accurate FPR product, the molding should be under flowing conditions:

• keep a constant temperature between 15 to 25℃ in the FPR molding workshop.
• keep the humidity under 75％ in the workshop too.

2. Raw materials Preparation

The raw materials used for FRP product are as follows:

• Fiberglass fabric and Fiberglass Felt
• Resin
• Coating

3. Mold Preparation

• Make the fiberglass mold according to the inner shape of the product and the precision requirement.
• Make sure it is smooth and no default on the surface.

4. Hand Paste Molding Technique

• Spray resin coat by American Douglas coat spray machine on the surface of the mold.
• Pre-make the reinforced bar according to drawings.
• Put the pre-make reinforced bar in the right place, and wrap it with fabric until it gets to the designated depth.
• Examine if the edge is leaking and it still has bubbles after pasting.

5. Solidity

• Make sure the solidify temp. is 25%±3℃, the humidity not above 80%(The workshop must be thermostatic and desiccative.)
• The mold cannot be taken off until it has been solidified for 10 hours (solidifying temperature 25±3℃) and the degree of cure has reached 80% ( Barcol rigidity> 41).

6. De-molding

• Push the mold out, prize and press are not allowed.
• Put the De-molding product on the soft fabrics and then move to the designated place in case distortion or abrade.

7. Final disposal

• Get rid of the thorn, bubbles on the surface, spray resin after the cleaning job.
• Cut the edge according to the design requirements.

Applications:

For maintenance


Competitive Advantage:

1.Non-slip and firmly
2.Convenience for Maintainence
3.Long life
4.Ageing Resistance and Ultraviolet
