Performance Characteristics Of Resin Trench Cover

{dede:global.cfg_gsname/} | Updated: 2020-01-11 03:24:00
Resin composite manhole cover is made of polymer composite material and has no recycling value.
In today's society, people ’s requirements for the environment and safety are becoming more and more stringent. Therefore, many trenches and drainage channels have cover plates for cable trenches. One is corrosion-resistant, acid- and alkali-resistant, lightweight, and beautiful. Diversity of colors.
The performance characteristics of the resin trench cover are as follows:
1. Corrosion resistance of resin trench cover: It has excellent corrosion resistance to many gas and liquid media such as acid, alkali, organic solvents and salts, and has unparalleled advantages in the field of anticorrosion. According to the requirements of actual use occasions, it can be economically selected to use o-benzene, m-benzene and vinyl resins as matrix materials.
2. Light weight, high strength, and easy to cut and install.
Because it is a composite of resin and glass fiber, its density is less than 2 and is only 1/4 of steel and 2/3 of aluminum. Its strength is 10 times that of rigid polyvinyl chloride, and its absolute strength exceeds the level of aluminum and ordinary steel. Its light weight can greatly reduce the foundation support, thereby reducing the material cost of the project. Its cutting and installation is simple, no fire and large lifting equipment are needed, and only a small amount of manual and electric tools are needed, which greatly reduces the installation cost.
3. Anti-aging: The service life is more than 50 years.
4. Flame retardant: The flame propagation rate (ASTM E-84) of ordinary flame retardant trench cover does not exceed 25; the flame propagation rate of high-grade flame retardant vinyl trench cover does not exceed 10. The oxygen index is not less than 28 (GB 8924).
5, safety: excellent electrical insulation, no breakdown at 10KV voltage; no electromagnetic properties, can be used on magnetic sensitive equipment; the special structure of the resin groove cover also has anti-skid, fatigue resistance and other characteristics.
6, uniform internal and external colors, and colors can be arbitrarily selected. Can customize colors according to customer requirements to improve the environment of the production site.
7. It has good comprehensive economic benefits.
8, strong design, flexible and diverse sizes, stable size.
Nowadays, there are more and more resin trench cover plates on the market, and the colors are also varied. I feel that there are no well covers that resin trench cover manufacturers cannot make. Exaggeratingly, only you can't think of it, without them they can't. Although the resin trench cover is easy to install, some inspection work needs to be done after installation:
1. For the brickwork of the inspection well, according to the size of the inspection well in the design atlas, a resin trench cover with a suitable inner diameter is selected.
2. According to the thickness of the resin trench cover and the height requirements of the top surface of the green belt fill, determine the top elevation of the bricks of the inspection well.
3. Before installing the resin trench cover in the green belt, it is required to have a thick filling in the green belt. It is advisable to not affect the installation of the well cover and the concrete placement of the well ring. The resin trench cover in the motorway needs to be installed after the first layer of asphalt concrete is paved. When the first layer of asphalt concrete is paved, the wellbore is covered with wooden boards. After the paved asphalt concrete has cooled, the wooden boards are removed and the asphalt concrete around the wellbore is removed. Cut edges to leave the dimensions of the manhole cover and its reinforced concrete. And remove all debris in the inspection well.
4. After checking that there is no problem in the elevation of the top surface of the brickwork of the well, sprinkle the top surface of the brickwork with water to moisten it. Use a 1: 3 cement mortar to sit in the 2cm thick cement mortar at the location where the well circle is to be installed, and then place the well circle inside the well circle. Mortar with brick wall. The installation should keep the foundation flat, and the well ring base should touch the ground as a whole without any looseness.
