유리섬유 막대는 어떻게 만들어지나요? 대한민국

유리 섬유 막대 is a kind of composite material with glass fiber roving and its products as reinforcing material and synthetic resin as matrix material. Its production process mainly includes the following steps:

1. 원료 준비:
Glass fiber roving: choose suitable glass fiber roving, such as E glass fiber roving.
Resin: Usually use unsaturated polyester resin, epoxy resin, etc., as binder and curing agent.
Auxiliary materials: such as curing agent, accelerator, mold release agent, etc.

2. Roving pre-molding:
Glass fiber rovings are laid on the mold according to the designed layers and directions to form a preformed body of the desired shape. This process can be laid by hand or automated by machine.

3. 함침:
The preformed fiberglass roving is dipped into the resin to ensure that the yarns fully absorb the resin. This step can be accomplished by a variety of methods, such as vacuum impregnation, pressure impregnation or transfer impregnation. For frp rods, the pultrusion molding process is usually used, whereby a specially designed die is used to continuously produce fiberglass rods of the desired size under traction.

4. Resin Curing:
The resin-impregnated fiberglass roving is cured in the mold. The curing process can be carried out at room temperature or accelerated by heating. During curing, the resin transforms from a liquid to a solid state, thus giving strength and shape to the composite.

5. Post-treatment:
경화 후, 유리 섬유 막대 are subjected to post-treatment processes such as cooling, cutting, deburring, sanding and inspection to ensure dimensional accuracy and surface quality of the product.

6. 품질 관리 :
In the whole production process, it is necessary to strictly control the quality of raw materials, the process parameters of the production process and the performance of the final product, to ensure that each 섬유 유리 막대 meets the quality standards in terms of size, shape, strength and appearance.

유리 섬유 막대 are widely used in sports equipment, industrial tools, electrical and electronic, agriculture and other fields because of their light weight and high strength, corrosion resistance, good insulation and other characteristics. During the manufacturing process, it is important to pay attention to environmental protection and safe production to reduce the impact on the environment and operators.
