The composite plate is composed of upper and lower color steel plate and middle foam polyurethane core material,using the world's advanced six components online automatic operation mixed pouring technology, can complete the ratio of social ingredients center or factory mixing process, and can be adjusted according to the temperature online, so as to produce distinctive high strength, energy saving, green building panels.

Polyurethane composite board can be divided into pure polyurethane composite board and polyurethane sealing edge composite board, due to its good fire and moisture-proof performance, is also commonly used in other material composite board sealing core material.

Process flow of polyurethane sandwich board production line:

Open roll —— coating —— cut edge —— sheet molding —— sheet preheat ——

Rock wool stacking feed —— lift —— strip cut (vacuuming) —— 90 flip—— whole line —— side slot (side gun) —— (rock wool spray glue ——Side foam) —— double track composite molding (insulation) —— disc saw cut(Vacuum) —— fast roller road —— stacking (flip plate) —— delivery —— packaging

Equipment composition:

Open rolling system, film cutting (with cutting edge winding), molding machine system, preheating furnace, rock cotton system, foam system, upper and lower rock cotton coating system, foam system auxiliary device, double crawler,

double crawler heating system, cutting system, palletizing system, packaging system, etc.

Auxiliary equipment mainly includes: rock wool dust removal equipment, short board cutting equipment, corner board making equipment, etc.

Advantages of polyurethane composite board:

Advantages of roof panel:

using dark nail connection, close board surface lap, unique waterproof tank design,

Effectively prevent rainwater infiltration, and avoid the cold bridge phenomenon, 40mm peak height, greatly improve the roof

Plate bearing capacity and drainage effect, while ensuring the thermal insulation effect of the building, can effectively reduce the customer construction

Built into this, the roof slope can be up to 3%

Advantages of wall panel:

dark nail connection, no exposed screws on the surface, corrosion resistance, excellent building wall.Beautiful and smooth, with a very high bending bearing capacity, wall mechanical properties are superior, reduce the auxiliary steel knot

Structure dependence, excellent insulation performance, reduce the cost of building indoor air conditioning equipment, a variety of appearance ,Effect, beautiful wall appearance.

Characteristics of polyurethane products:

1. Light weight, good thermal insulation and heat insulation performance

2. Flexible and convenient installation and simple construction

3. Good fire retardant, reaching the national fire prevention standards

4. Wide use temperature range and high temperature resistance

5. Low thermal conductivity

6. Non-toxic, tasteless and pollution-free

7. Waterproof and moisture-proof

8. Soak by black and white material according to a certain proportion
