Foam Insulation Sandwich Panel Production line

This production line is mainly composed of a laminating machine and a high-pressure foaming machine, which are mainly used to produce sandwich panels. The laminating machine is composed of a frame and a loading template. The mold closing method is completed by hydraulic drive, and the loading template uses a water heating mold temperature The machine is heated to ensure a heating temperature of 40°C, and the whole can be tilted by 0 to 5 degrees. In order to facilitate the loading and unloading of the upper part, the up and down moving template can automatically enter and exit the laminator, and the return moving template can be produced alternately, which improves the production efficiency.

Basic Structure And Working Principle Of High Pressure Foaming Machine:

Liquid polyol and isocyanate raw materials are stored in two tanks respectively, and two rotary axial plunger (or radial piston) metering pumps send the raw materials to the mixing head. When the mixing head is opened under hydraulic pressure, the two components are injected into a small mixing chamber at high pressure and flow rate, collide with each other, achieve the purpose of mixing through energy conversion, and flow out of the mixing head into the mold cavity. After the injection time is over, the piston rod of the mixing head is pushed forward, and all the materials are pushed out of the mixing chamber, and at the same time, the wall of the mixing chamber is cleaned by the piston rod without leaving any residual materials. Components are returned to the tank through return channels on both sides of the piston rod. If there is no injection for a long time, the high and low pressure cycle switching device will control the two components to enter the low pressure cycle.

Because the machine measures accurately, the material loss is small, and does not need solvent cleaning, it is beneficial to environmental protection and reduces the cost of raw materials. Therefore, it has been more and more widely used in various fields.

Cold Storage Board Series

Colored steel storage panel Polyurethane with good heat insulation performance is used as the inner material, and the sandwich type storage panel made of color steel plate on the outside can reduce the heat transfer caused by the temperature difference between the inside and outside, so as to achieve the maximum efficiency of the freezing and refrigeration system. It is scientific in design, simple and practical, and is a new type of heat insulation material that can save construction costs.

Precautions For Installation Of Cold Storage Board

"Cold Bridge" Blocking

It is unlikely that the thickness setting is in compliance with the regulations. Put an end to steel plate violation connection, building structure. Equipment piping. The "cold bridge" formed by the support penetrating the insulating sandwich panel etc. is very important. Reducing this external burden can reduce operating costs. More importantly, it will meet the technological requirements of "less fluctuations in body temperature" for food cold sinks and cold processing, which will help reduce food dry consumption and maintain food quality. Blocking new cold bridges can be realized by practical and reliable node practices.

"Steam Bridge" Blocking

After the cold storage cools down, the volume of the gas in the heat insulation layer shrinks, and the water vapor contained in the air acts from the high pressure side to the low pressure side, that is, a pressure difference is formed inside and outside the heat insulation layer. After the steam is pressurized, it can penetrate through the tiny barriers and enter the heat-insulation chamber, and penetrate into the interior with lower temperature and lower pressure.

The water vapor turns into water after cooling. After the temperature is further lowered, the water condenses into ice, and the foam of the insulation layer contains wood or ice, which will destroy its insulation performance, which will affect the operation of the overall cold storage and shorten its service life. relatively. In terms of "cold bridge." "Steam bridge" is often ignored. When installing the panels, all "steam bridges" must be blocked to reduce the impact of water vapor on the flame-retardant foam.

Strength Requirements

The cold room has a large temperature difference between inside and outside. The fixing method of building sandwich panels and the design of structural nodes for long-term operation of refrigeration equipment. The installation must be able to resist the worst possible combination of various external forces. mainly include:

●External loads of enclosure wall panels and top slabs

■The thermal bending of the inner and outer surface materials of the sandwich panel due to the temperature difference

●Pressure changes caused by temperature changes in the storage

■ Sandwich panel surface contamination. Damage caused by corrosion and external force impact The compressive strength and long-term load deformation of the cold storage floor insulation layer material--sandwich panels are due to the material. Stress remaining in the process of manufacturing and installation

Security Requirements

Cold storage is not only a building, but also a long-term operating "equipment", and there are many unsafe factors. must be taken seriously
