Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a toughened PVC-U pipe for breeding. Background Art

[0002] PVC-U pipe refers to rigid polyvinyl chloride pipe, which is made of polyvinyl chloride resin as the main raw material without adding plasticizer. PVC-U pipe has been widely used in many fields due to its unique properties. Due to these advantages, PVC-U pipe is widely used in water supply and drainage systems, farmland irrigation, cable protection, chemical fluid transportation and other purposes. However, PVC-U pipe also has some limitations. For example, there may be a risk of deformation when used for a long time at high temperatures, and it does not have good toughness. Therefore, in some applications in breeding and other industries, it is necessary to improve its toughness and temperature resistance through modification.

[0003] For example, a high-toughness anti-drip PVC-U pipe disclosed in Chinese patent announcement number (CN205350614U) is provided with an inner layer, a middle layer and an outer layer from the inside to the outside, the contact surface between the inner layer and the middle layer is a concave-convex surface that matches each other, and the contact surface between the outer layer and the middle layer is also a concave-convex surface that matches each other, the inner layer is a modified polyvinyl chloride layer, the middle layer is a polyurethane layer, the outer layer is a polyetheretherketone layer, and a plurality of reinforcing ribs are provided inside the inner layer along the length direction, and the cross-section of the reinforcing ribs is gear-shaped; the advantages of this utility model are: high temperature resistance, high toughness, good compressive resistance, and the inner and outer layers of the pipe wall are firmly combined, which improves the product strength and prolongs the service life.

[0004] However, the above patent still has the problem of poor toughening and protective effect on PVC-U pipes. For example, in the above patent, the contact surface between the outer layer and the middle layer is also a concave and convex surface that matches each other. The inner layer is a modified polyvinyl chloride layer, the middle layer is a polyurethane layer, and the outer layer is a polyetheretherketone layer. A plurality of reinforcing ribs are arranged inside the inner layer along the length direction. The cross-section of the reinforcing ribs is gear-shaped to improve the toughness and compression resistance of the pipe. However, the toughening setting in this method is uneven, and puncture sites are prone to occur. When in use, the part without reinforcing ribs is prone to deformation during bending, affecting the liquid flow efficiency. Utility Model Content

It is particularly suitable for aquaculture water transportation in harsh environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 In this embodiment, a toughened PVC-U pipe for aquaculture includes a base layer 1, a toughening component 2 for increasing the toughness of the pipe is provided on the outside of the base layer 1, and a protective component 3 for improving the protective effect of the pipe is provided on the outside of the toughening component 2.

[0022] See also Figure 2In order to improve the toughening effect of the pipe, the toughening component 2 in this embodiment includes a toughening layer 21, a reinforcing filler layer 22 and a lubricating layer 23. The toughening layer 21 is fixed to the outer side of the base layer 1. The toughening layer 21 can improve the impact resistance and toughness of the pipe. CPE can absorb and disperse energy when subjected to external force through the flexible segments in its molecular structure, thereby improving the crack resistance and environmental stress cracking resistance of the pipe. The reinforcing filler layer 22 is fixed to the outer side of the toughening layer 21. The reinforcing filler layer 22 can improve the hardness, rigidity and chemical corrosion resistance of the pipe. Calcium carbonate particles can fill the microscopic gaps of the PVC-U resin and improve the overall strength and stability of the pipe. Silicon dioxide can further improve the wear resistance and impact resistance of the pipe. The lubricating layer 23 is fixed to the inner wall of the base layer 1.

[0023] In this embodiment, the base layer 1 is a PVC-U layer, the toughening layer 21 is a chlorinated polyethylene resin layer, the reinforcing filler layer 22 is a filler layer, and the lubricating layer 23 is a PE wax layer. The lubricating layer 23 serves as an inner wall lubricant, which can reduce the friction coefficient of the inner wall of the pipe, improve the wear resistance of the pipe, improve the fluidity inside the pipe, and reduce friction during use.

[0024] See also Figure 3 In order to enhance the toughness and protection effect of the pipe, the protection component 3 in this embodiment includes a stabilizing layer 31, a covering layer 32 and a surface protection layer 33. The stabilizing layer 31 is fixed to the outer side of the reinforcing filler layer 22. The stabilizing layer 31 provides primary protection for the pipe to prevent damage to the pipe caused by environmental factors such as ultraviolet rays and oxidation. The lead-free formula ensures the environmental friendliness of the pipe and is suitable for the transportation of drinking water or aquaculture water. The covering layer 32 is bonded to the outer side of the stabilizing layer 31. The covering layer 32 provides additional mechanical protection for the pipe to prevent physical damage such as scratches and impacts, and can block part of the ultraviolet rays to extend the service life of the pipe. The surface protection layer 33 is fixed to the outer side of the covering layer 32.

[0025] In this embodiment, the stabilizing layer 31 is a lead-free mixed plastic layer, the covering layer 32 is a polyethylene layer, and the surface protection layer 33 is an epoxy resin coating. The surface protection layer 33 is the outermost layer of protection, which can provide excellent corrosion resistance, chemical resistance and wear resistance. The protective effect of the epoxy resin lies in the hard coating it forms, which can effectively prevent the erosion of the pipe by external factors, while providing a smooth surface to reduce the attachment and growth of microorganisms.

[0026] It should be noted that the toughened PVC-U pipe can provide excellent chemical corrosion resistance and environmental resistance while ensuring sufficient strength and toughness, and is particularly suitable for transporting aquaculture water in harsh environments.

[0027] The working principle of the above embodiment is:

[0028] (1) When the toughening effect of the pipe is improved, the toughening layer 21 can improve the impact resistance and toughness of the pipe. The CPE can absorb and disperse energy when subjected to external force through the flexible chain segments in its molecular structure, thereby improving the crack resistance and environmental stress cracking resistance of the pipe. The reinforcing filler layer 22 can improve the hardness, rigidity and chemical corrosion resistance of the pipe. The calcium carbonate particles can fill the microscopic gaps of the PVC-U resin and improve the overall strength and stability of the pipe. The silicon dioxide can further improve the wear resistance and impact resistance of the pipe. The lubricating layer 23 acts as an inner wall lubricant to reduce the friction coefficient of the inner wall of the pipe and improve the wear resistance of the pipe.

[0029] (2) When the pipe is used to enhance its toughness and protect it, the stabilizing layer 31 provides primary protection for the pipe to prevent damage to the pipe caused by environmental factors such as ultraviolet rays and oxidation. The lead-free formula ensures the environmental friendliness of the pipe and is suitable for the transportation of drinking water or aquaculture water. The covering layer 32 provides additional mechanical protection for the pipe to prevent physical damage such as scratches and impacts, and can block part of the ultraviolet rays to extend the service life of the pipe. The surface protection layer 33 is the outermost layer of protection and can provide excellent corrosion resistance, chemical resistance and wear resistance. The protective effect of the epoxy resin lies in the hard coating it forms, which can effectively prevent the erosion of the pipe by external factors and provide a smooth surface to reduce the attachment and growth of microorganisms.
