Product Overview

Description

High strength explosion-proof anti-corrosion

and anti-breakdown coating

Hangzhou Feijie Technology Co., Ltd. was established in December 2008. The company name "Feijie" takes the homonym of phase change material (PCM-Phase Change Material). It is the first professional research and development of phase change material technology in China. Production of high-tech companies. The company introduced the University of California, Irvine, Zhejiang University, and is at the forefront of international microcapsule technology and gas condensation technology. In 2016, our company was awarded the “National Green Textile Material Phase Change Microcapsule R&D Center” by the China Textile Engineering Society, and participated in the drafting of “National Standards for Textile Phase Change Thermostat Microcapsules and Their Application Functions Evaluation”. In 2016, phase change materials shipped to 8,000 tons, making it the largest supplier of phase change materials in Asia. At present, it has obtained 8 invention patents and a number of utility model patents.

 

High strength coating technology

High-strength coating is currently the most advanced polymer nanomaterial in the world, with a density of only 1.0--1.2. It is widely used in military, industrial, automotive and other industries. It has high strength, high corrosion resistance, high toughness, simple construction, no VOCs, etc. Features.

 

I. Current situation at home and abroad

    The main foreign providers currently are the US line-x and the US Unicorn Materials Laboratory. The first generation of products developed by American line-x company in the 1990s is mainly for civilian equipment such as trucks and off-road vehicles. With the upgrading of product performance, its application has gradually turned to the military industry since 2008, including the Pentagon. The protection of explosion-proof protection, ship submarines, tank armored vehicles, bullet-proof vesting boards and other equipment has practical significance for reducing equipment weight and increasing combat effectiveness.

     Uni-Li Materials Laboratory mainly applies anti-corrosion, waterproof and reinforcement of bridges and buildings for civil products. The military also has some applications for explosion-proof. The overall product performance is slightly weaker than line-x.

China has started research and development and application of similar products since 2005. At present, the main research units are Yantai Wanhua Company and Qingdao University of Technology, all of which have developed second-generation technology, but there is no mature explosion-proof product.

 

2, product overview

2.1 Technology evolution

At present, high-strength coatings can be divided into four generations according to their technological evolution. See the following figure for details:

stage	Age	Features
The first generation	1990s	Waterproof, anti-corrosive
The second generation	20001-2005	Waterproof, anti-corrosive, weather resistant, and has a certain protective strength
The third generation	2006-2010	Waterproof, anti-corrosive, weather resistant, high anti-explosion
The fourth generation	2011-Until now	Waterproof, anti-corrosive, weather resistant, high anti-explosion,resistance to breakdown
The fifth generation		Waterproof, anti-corrosive, weather resistant, high anti-explosion, high resistance to breakdown

 

 

2.2 Object-Oriented

At present, high-strength coatings are widely used in various fields such as metal, wood, glass, concrete, textile fabrics, plastics, foams and the like.

 

2.2 Construction process

Through the A and B tubes of the high pressure spray gun, the atomization mixing effect is formed, which is polymerized on the surface of the workpiece material and dried quickly for 5-10 seconds to form a tough protective film whose color can be adapted according to the applied battlefield environment.

Anti-breakdown

 

The impact strength of the currently coated product is converted to 75 kj/cm2. At a distance of 5 cm, the explosive force per tct of tnt is 33 kj/cm2, which can withstand 2.27 kg of tnt explosive.

 

 

Antiknock 

       A 2 mm yellow high-strength coating was applied to a steel pipe 30 cm in diameter and 6 mm thick. With 5 kg of tnt explosive, the coating was only slightly blackened and the steel tube was not deformed and remained intact.

Corrosion resistance

 

Working mechanism

    The product is microscopically closed to the micron-scale carbon dioxide, similar to the honeycomb structure (see Figure 1). When impacted, the wall of the hole bends, creating a linear elasticity, and when the critical stress is reached, the hole begins to collapse. Due to the elastomeric material, the collapse is caused by the elastic buckling of the wall of the hole, so it can be recovered (see Figure 2). When the external load does not reach the ultimate yield strength, it is in the linear deformation zone, and the impact force is offset by the strength of the material itself; when the ultimate yield strength is exceeded, the stress begins to rapidly conduct to the outside through the deformation of the honeycomb structure. It is based on such a structure that the stress can be dispersed to the entire surface of the workpiece in milliseconds.
