Embodiment 1
[0045] A method for preparing a carbon / carbon cylinder by a winding process, comprising the following steps:
[0046] (1) Prepare a sealed heat shield with a specification of φ115*φ109*550mm according to the requirements. First, use graphite material to design and manufacture a molding mold. The outer diameter of the molding mold is 106mm. The inner diameter and the shape of both ends match the rotating tooling of the winding equipment.
[0047] (2) This product is used to transmit corrosive gases and requires very good sealing performance. Therefore, the cylinder adopts a winding structure that combines graphite paper, carbon cloth and carbon wire in proportion. The number of graphite paper layers is 5 layers, and graphite The paper thickness is 0.3mm, and the mass ratio of carbon cloth to carbon filament is 1:1.
[0048](3) First install the forming mold on the rotating shaft and fix it on the winding machine, then lay a release paper layer on the surface of the graphite cyl...
Embodiment 2
[0062] (1) Prepare a structural cylinder of φ780*φ750*800mm according to the requirements. Firstly, use graphite material to design and make a molding mold. Rotary tooling to match.
[0063] (2) According to the functional requirements of the cylinder, the product structure is designed. The structural cylinder adopts carbon cloth and carbon wire to form a combined structure in proportion. The mass ratio of carbon cloth and carbon filament in the structural cylinder is 1:10.
[0064] (3) First install the forming mold on the rotating shaft and fix it on the winding machine, then lay a release paper layer on the surface of the graphite cylinder, and stick it tightly with plastic tape, so that the release paper is in a tight state, and the release paper layer It is composed of graphite paper and sulfuric acid paper. The number of graphite paper layers is 2 layers, and the sulfuric acid paper is 1 layer. From the inside to the outside, it is sulfuric acid paper, graphite paper, an...
Embodiment 3
[0078] A method for preparing a carbon / carbon cylinder by a winding process, comprising the following steps:
[0079] (1) Prepare a sealed cylinder of φ668*φ662*535mm according to the requirements. Firstly, use graphite material to design and make a molding mold. Rotary tooling to match.
[0080] (2) According to the functional requirements of the cylinder, design the product structure. The sealed cylinder adopts a winding structure that combines graphite paper, carbon cloth and carbon filament in proportion. The number of layers of graphite paper in the sealed cylinder is not low For 3 layers, the thickness of graphite paper is 0.4mm, and the mass ratio of carbon cloth to carbon filament is 1:5.
[0081] (3) First install the forming mold on the rotating shaft and fix it on the winding machine, then lay a release paper layer on the surface of the graphite cylinder, and stick it tightly with plastic tape, so that the release paper is in a tight state, and the release paper la...
