Product Features Of New FRP Composite Material High Temperature Molding Press

{dede:global.cfg_gsname/} | Updated: 2020-01-16 02:23:00
Glass fiber reinforced plastic composite manhole covers and cover plates use glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcing materials, and synthetic resin as the matrix material, mainly composed of unsaturated polyester resin, filler, initiator, thickening Additives, low shrinkage additives, film mold agents, pigments and reinforcing materials. New SMC moulded manhole cover manhole cover size 300mm, 500mm, 700mm load capacity light: 20KN heavy: 300KN extra heavy: 400KN
The new SMC moulded manhole cover is a new type of colorful high-strength manhole cover. It is molded by advanced technology and equipment. The heavy manhole cover has a carrying capacity of more than 400KN. At the same time, it has been tested by the National FRP Quality Supervision and Inspection Center. This product is normally used at -40 ° C to 90 ° C. It has a long service life and is a replacement product for various other manhole covers. Widely used in municipal, pipeline, channel, power supply, water supply and other projects.
composite manhole cover
1. Strong anti-theft performance: Resin composite material manhole cover is made of unsaturated resin, glass fiber and other materials and reinforced skeleton composited by special production process. After high temperature grinding and pressing, the material has no use value, and it is very difficult to remove the steel bar (rebar cost) (Beyond the value of rebar) is therefore anti-theft.
2. Large bearing capacity: the bottom adopts a special bottom-shaped structure, which increases the load-bearing area. The continuous reinforcing fiber yarn used guarantees that the fiber yarn and the glass fiber cloth are integrated into one material, so that the product has sufficient bearing capacity.
3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, to ensure the penetration of resin in glass fiber, greatly enhance the adhesion between the two, so that the material under the action of cyclic loading, so Guaranteed product life.
4. Beautiful and practical, high-grade: According to customer needs, LOGO and a variety of colors of personalized design can be made to make the pattern delicate, colorful and clear. According to customer requirements, we can make all kinds of imitation stone surfaces and colors the same as various stone pavements.
5. High temperature / low temperature resistance, good insulation performance: the product is corrosion resistant. Played a good insulation effect.
Can be used in complex, changeable, harsh, and demanding places. The product has been tested by relevant national testing agencies and has obvious resistance to acid and alkali and corrosion.
6.Environmental protection, non-slip, low noise: This product does not slip, no harsh noise and anti-interference phenomenon after the car is rolled. At the same time, due to the light weight of the product, the cover and seat are fastened accurately to overcome
In addition, other problems such as running, jumping, rocking, ringing, and shifting of the inspection manhole cover were introduced.
Product Features
Resin composite manhole cover is made of polymer composite material without any recycling value. After the popularization of resin manhole covers, the problem of urban black holes caused by theft of manhole covers will be solved. Different from the manhole cover on the market, it is pressed out by hydraulic press, and has high impact strength.
This resin composite manhole cover is made of glass fiber and resin as basic materials, and auxiliary materials such as curing agent and accelerator. It weighs two-thirds lighter than cast iron manhole covers and has a long service life. The price is only 80% of that of cast iron manhole covers. At the same time, this manhole cover also has the characteristics of insulation and no noise.
