The winding process of the cylinder belongs to the molding process of the gas cylinder, and is mainly used to solve the problems of complicated process, serious material waste, low production efficiency and low qualification rate in the manufacturing process of the gas cylinder. What kind of technology does it have for manufacturers?
The winding process of the cylinder:
①wet winding process:
Refers to the process of winding the fiber yarn belt of the rubberizing equipment on the core mold according to the designed parameters. After the winding process of the liquefied gas cylinder is finished, the curing process is performed to obtain the final product. The economics of wet entanglement are better because the method requires less equipment and therefore reduces investment. However, this method causes a large amount of harmful substances such as solvents to volatilize and cause pollution. In addition, the process parameters in the winding process are not easy to control, so the quality stability of the product is relatively poor.
②dry winding process:
Refers to the process of preparing the composite material into two stages. The first stage of the process is used to process the preparation body containing the matrix and the reinforcement. The preparation body can be stored for future use, but the preparation body The storage time should be within the shelf life of the shelf life, otherwise it will not continue to be used due to physicochemical reactions. In the second stage, a preparative body processing is used to obtain a fiber-wound liquefied gas cylinder shell structure of stable quality.
In addition, dry winding reduces solvent volatilization compared to wet winding of cylinders, which reduces environmental pollution and, more importantly, helps to create a healthy and clean working environment. In addition, this method is more suitable for the promotion and application of automation equipment. However, the equipment used is more and the investment required is larger.
