Shandong Lumeng VRA (vinyl ester)-type III concrete structure anti-corrosion coating

1. Product Introduction
(Vinyl Ester)
Concrete structure anti-corrosion coating
It is an anti-corrosion coating independently developed by Yantai Development Zone Lumeng Waterproof and Anti-corrosion Materials Co., Ltd. and is suitable for Protection of concrete structures. According to the requirements of the national standard "Anti-corrosion Design Code for Industrial Buildings", we developed
(vinyl ester)
anti-corrosion coating for concrete structures
. (Vinyl ester) type concrete structure anti-corrosion coating is mainly used for the anti-corrosion of concrete structures in corrosive environments. Most anti-corrosion coatings in our country are solvent-based coatings, and most of the resins used are epoxy series products. These coatings become rigid after curing and have poor impact resistance. If used for concrete anti-corrosion, the base layer must be very dry before construction, and it itself It is toxic, pollutes the environment during construction, and has no crack resistance. (Vinyl ester) type anti-corrosion coating for concrete structures
is non-toxic and non-polluting. It can be applied on both dry and wet surfaces of concrete. The coating after application is highly elastic and can resist micro-cracks in concrete. Leakage and corrosion! It is easy to construct, fast to film, and has strong adhesion. The successful research on (vinyl ester) type anti-corrosion coating for concrete structures has added a very good variety of water-based anti-corrosion coatings to our country. Through Harbin Beijiao Sewage Treatment Plant, Changchun Southern Suburb, Beijiao Sewage Treatment Plant, Shaoxing Sewage Treatment Plant Phase II, Yingkou Sewage Treatment Plant, Tianjin Dagang Sewage Plant, Shenzhen Sewage Treatment Plant, Yantai Development Zone Water Plant and Sewage Treatment Plant, etc. Hundreds of sewage and water supply plants have used it with ideal results. It has made great contributions to the anti-corrosion of concrete structures in my country, reducing pollution, improving anti-corrosion efficacy and creating a green environment.
Our company has passed the quality management system certification/environmental management system certification//occupational health and safety management system certification
It has been successfully used in water supply and drainage projects in China for eighteen years

4. Scope and conditions of application
(Vinyl ester)
Anti-corrosion coating for concrete structures
Mainly suitable for industrial and civil building protection, anti-corrosion and waterproofing such as industrial and domestic sewage treatment It is suitable for the protection of concrete structures in factories, anti-corrosion in non-toxic environments such as bioengineering, pharmaceuticals, and water plants, and the protection of water pipelines. It is also suitable for the anti-corrosion of the inner wall of the water drying tower in power plants, the anti-corrosion of concrete structures in landfills, and the anti-corrosion of concrete structures in coastal environments or in sea water.
5. Construction Operating Procedures
(vinyl ester)
Anti-corrosion coating for concrete structures
The biggest feature is that there are no special requirements for the shape, location, type of base, etc., and its applicability Strong and suitable for various concrete structure bases, its construction operations can be summarized into the following three links.
(1) Base layer preparation
The base layer must be smooth, with a compacted and polished surface, no sharp edges, no honeycomb pits, and no bulging cracks, otherwise it must be processed to meet the above requirements.
, Surface construction waste and floating ash must be removed.
There should be no open water on the base layer, otherwise it should be removed and cleaned.
(2) Material Preparation
Material preparation can be done mechanically or manually.
When large-area anti-corrosion construction requires urgent work, mechanical spraying or mechanical preparation can be used (our company has special mixing equipment). In general, manual preparation is used.
(3) Coating construction
(vinyl ester)
Anti-corrosion coating for concrete structures
can be sprayed mechanically or manually.
, Mechanical spraying
Using high-voltage spraying equipment and a single-phase motor, the equipment weighs only kilograms. A construction team of three people can complete multiple square meters per shift.
, manual painting
Use a long plate brush or a round rolling brush of ~ or above for painting. The painting should be done horizontally and vertically to achieve a smooth, even and consistent thickness.
6. Precautions
This product should be stored in a cool, dry place to prevent exposure to sunlight and freezing.
The effective storage period is half a year, and the storage temperature is above ℃ and below ℃.
