The coating process of double-layer sintered epoxy powder coating is relatively simple. It only needs to be fine-tuned on the basis of the original single-layer sintered epoxy powder spraying equipment. That is, the spraying equipment is divided into three groups, and the first group is sprayed with the bottom layer powder. , the second group sprays outer layer powder, and the third group sprays recycled powder. The sprayed powder can be recycled separately or together. The scratch resistance of a single layer is relatively poor, and the constructability is affected. In order to improve this system and overcome the above shortcomings, we focused on material modification and proposed a two-layer coating anti-corrosion system, that is, using the standard coating as the base coating and the modified coating as the outer anti-corrosion layer. This double-layer coating anti-corrosion system further improves the mechanical properties, enhances the coating's impact resistance, scratch resistance, high temperature resistance and high temperature permeability resistance, while maintaining the compatibility of the single-layer coating with cathodic protection. performance and does not create a cathodic protection barrier. The thickness of the overall coating is ~, and the maximum operating temperature reaches ℃. It can be applied to the anti-corrosion coating of steel pipes, elbows, special-shaped parts and patchwork of various diameters. The main powder coating methods include: electrostatic spraying, thermal spraying, suction, fluidized bed, etc.
The three-layer process of using epoxy powder coating as base polyethylene and adhesive winding or coating is a commonly used steel pipeline anti-corrosion process at home and abroad. It is also the current domestic West-East Gas Transmission and Oilfield Oil Transmission. , gas, pipeline anti-corrosion technology used in urban gas and water supply. Treatment principles of anti-corrosion process The quality of pre-treatment has a great influence on the performance of the coating. In the actual coating process, there are many examples of failure to achieve the expected anti-corrosion effect due to poor pre-treatment. In particular, many anti-corrosion coatings with excellent performance can only form normal coatings in strict accordance with their respective requirements. To achieve the expected anti-corrosion protection, the steel substrate must undergo rust removal, degreasing and phosphating treatment. The thickness of the anti-corrosion coating must exceed its critical thickness to play a protective role, generally mum~mum. If the primer is left for too long before the topcoat is applied, it will be difficult to adhere and affect the overall protective effect. The new process of epoxy powder dipping. Epoxy powder has always been applied using the electrostatic spraying process. Because the epoxy powder dipping process is plagued by adhesion problems, epoxy powder dipping has never been widely used. In recent years, with the successful development of Sanye's special phosphating solution for epoxy powder dipping, the adhesion problem of the epoxy powder dipping process has been overcome for the first time, and the emerging process of epoxy powder dipping has begun to be promoted. The spiral steel pipe sintered epoxy powder outer coating (B) is a new anti-corrosion layer developed in recent years. The B coating has two types: single layer and double layer. The so-called B coating generally refers to a single layer of sintered epoxy coating. The single-layer B coating uses special sintered epoxy powder coating as the film-forming material.
Issues solved with raw material manufacturers. Powder coatings have high coating efficiency and no pollution, and the development of new epoxy powder coatings, especially new epoxy resins, is still of great significance. Experts introduced new epoxy varieties used in powder coatings, as well as the current status and problems in the application process. Epoxy powder has always been applied using an electrostatic spraying process. Because the epoxy powder dipping process is troubled by adhesion problems, the epoxy powder dipping has never been promoted. In recent years, with the successful development of Sanye's special phosphating solution for epoxy powder dipping, the adhesion problem of the epoxy powder dipping process has been overcome for the first time, and the emerging process of epoxy powder dipping has begun to appear. Anti-corrosion standard b Epoxy powder anti-corrosion implementation/"Technical standards for fused epoxy powder outer coating of steel pipelines"/Anti-corrosion implementation/(Test) "Technical standards for polyethylene outer coating of buried steel pipelines" Anti-corrosion surface rust removal standards : The outer surface of the steel pipe is sandblasted and rust-removed as required, and the depth of the anchor pattern on the surface of the steel pipe is within mum. The structure of double-layer sintered epoxy powder. The double-layer sintered epoxy powder system is composed of two different sintered epoxy powders sprayed into a film at one time during the spraying process. The bottom layer is an ordinary single-layer epoxy powder layer, which provides The outer layer has enhanced anti-corrosion and adhesion properties to provide resistance to mechanical damage. The middle of the two layers is a mixed layer. Because the base materials of the two layers have the same molecular structure, they have good compatibility and can form an organic whole. , there will be no interlayer separation. The overall thickness of the entire coating is ~ , and the operating temperature can reach ℃. It can be applied to anti-corrosion coating of steel pipes of various diameters. The double-layer sintered epoxy powder anti-corrosion system has the following advantages: high bonding strength to the substrate, good resistance to cathodic peeling, low water absorption, wide operating temperature range, comprehensive performance equivalent to three-layer anti-corrosion coating, scratch resistance Excellent, double-layer is used for repairing, good compatibility, easy operation, easy quality control, smooth surface of the covering layer, which can avoid cathode shielding problems, and has better matching with the cathodic protection system than the three-layer structure. This is a newly developed covering layer in the world. It is most suitable for use in crossing areas and areas with strong corrosion. The disadvantage of the double-layer sintered epoxy powder anti-corrosion system is its high cost.
