Introduction

The polyurethane sandwich panel [1] refers to a composite panel made of a high-quality color-coated steel sheet as a panel, a core material using a polyurethane material, and a high-temperature foaming curing. MasterCard polyurethane sandwich panel adopts the world's advanced six-component online automatic operation mixing and pouring technology, which can complete the mixing process of the social batching center or the factory in one time, and can be adjusted freely according to the temperature, thus producing a unique difference. High-strength, energy-saving, green building panels.

  

Advantage

(1) 26m double track forming equipment to ensure a more flat layout.

(2) The six-component foaming machine is different from the two-group foaming machine currently used in China, and the composition control is more precise.

(3) The color-coated plate of well-known domestic manufacturers with more than 10,000 tons of standing stock, no color difference, stable quality.

Wall-mounted European style

Performance description

■ Five-sided trapezoidal socket, tightly inserted, convenient construction and quick installation.

■ Increase the use rate of steel plates and make them economical.

 

Roofing European tower connection

Performance description

■ The lap joint is treated with a hemming process. The lap joint is tighter, avoiding the corrosion of the edge due to no coating, prolonging the service life of the board and increasing the strength. On the other hand, it avoids the damage caused to the construction workers.

■ Wave height 34mm three-wave peak design improves the bearing capacity of the roof slab, reduces the use of roof rafters, enhances load capacity, and has balanced flow.

■ Designed to prevent water seepage from the sink.

 

Roof European hidden nail

Performance description

■ The screws are concealed and the water resistance is excellent, which prevents the corrosion of the screws and avoids the occurrence of cold bridges.

■ The peak height of 40mm and three wave peaks improve the bearing capacity of the roof slab, reduce the use of roofing rafters, enhance the load capacity, and balance the flow of water.

 

Polyurethane cold storage board

Performance description

■ The unique convex groove structure improves the tightness of the plate socket.

■ The board is even and stable, with good thermal insulation performance and good waterproof performance.

■ Convenient construction and quick installation.

 

Application field

Frozen food processing and refrigeration (aquatic products, poultry, poultry, food, vegetables, fruits), meat products production plants, food processing plants, fabricated cold storage, seed storage, biological and pharmaceutical products, dairy products storage.

 

Fundamental contents

Polyurethane sandwich panel polyurethane sandwich panel sandwich panel bonding strength is not less than 0.09MPa, sandwich panel combustion performance reaches B1 grade, bending capacity bearing sandwich panel deflection is Lo / 200 (Lo is the distance between the supports) The bending capacity of the sandwich panel is not less than 0.5Kn/m2. This product has the following characteristics: It has non-combustible, moisture-proof, insect-proof, soundproof, light weight, dry and wet without deformation, heat preservation effect, and can be nailed, sawn, simple and convenient to construct, and can be recycled repeatedly. The molding is once synthesized in the mold without the need for an interface bonding agent. If the surface layer of the composite board is a metal plate, the product's folding resistance is enhanced, the product's fire resistance is improved, the product does not crack, break, and has wear resistance and smooth surface quality. It is small in shrinkage and non-brittle at low temperature, suitable for cold storage and garage door waiting.

Overview

Anti-leakage sandwich roof panel, polyurethane rigid foam insulation board, polyurethane composite board, PU board, is a popular saying of polyurethane sandwich panel. Strictly speaking, it should be a polyurethane insulation sandwich panel for construction. The national standard is GB. /T 23932-2009, the old standard of replacement is JC/T868-2000.

 

Use

The product is a bimetallic surface, single metal surface, non-metal composite sheet with polyurethane rigid foam as insulation layer, which is usually used in industrial plants, logistics storage, integrated house wall and roof enclosure system.

 

Data

The bonding strength of polyurethane sandwich panel is not less than 0.09MPa, the combustion performance of sandwich panel reaches B1 grade, and the flexural capacity of sandwich panel is Lo/200 (Lo is the distance between supports), the bending load of sandwich panel The force is not less than 0.5Kn/m2. The effective width of the sheet is usually 1000mm and the length can be customized.

 

Process

The production of polyurethane sandwich panels requires an advanced continuous production line of sandwich panels. The process is formed by cold-bending forming of inner and outer galvanized (aluminum-zinc-plated) color steel plates and intermediate-coated polyurethane rigid foam.

The patented anti-leakage sandwich roof panel is the ultimate in the advantages of polyurethane sandwich panels.

 

Air tightness analysis

 

Roof panel advantage

Polyurethane sandwich panel polyurethane roof panels are connected by studs and the panels are tightly joined.

The unique waterproof tank design prevents rainwater from penetrating and avoids cold bridges.

The 40mm peak height greatly increases the bearing capacity of the roof panel. While ensuring the insulation effect of the building, it can effectively reduce the cost of the customer's construction, and the roof slope can be as low as 3%.

 

Wall panel advantage

The studs are connected, the surface is free of exposed screws, and the building walls are beautiful and smooth.

Extremely high flexural capacity, superior mechanical properties of the wall, reducing the dependence on the auxiliary steel structure.

Excellent insulation performance, reducing the cost of building indoor air conditioning units.

A variety of appearance effects, beautiful wall.
