What Are the Differences Between PU and PIR Sand

PU sandwich panel and PIR sandwich panel are both sandwich panels and important products of the sandwich panel production line. So what are the characteristics of these two different sandwich panels? What's the difference between them?

PIR foam and PUR polyurethane foam are two completely different thermal insulation materials, but since they have the same or similar reaction groups, that is, the raw materials used are the same or similar, they are called sister products. PIR is called polyisocyanurate acid-modified polyurethane. It is made of polyurethane foam modified by polyisocyanurate acid. It has a great difference in performance between polyisocyanurate and polyurethane. However, due to the fact that there are few factories that control PIR technology, the two kinds of foams are fundamentally indistinguishable in shape. Many people mistake that PIR is also polyurethane foam. In fact, there is a big difference between the two. The full name of PIR, "polyisocyanurate acid-modified polyurethane", is too long to memorize, so we usually call it PIR foam or polyurethane PIR foam, and call it the regular polyurethane foam polyurethane PUR foam (or PU foam) to show the difference.

1. What is a PU sandwich panel?

PU sandwich panel, also known as polyurethane sandwich panel, polyurethane composite panel and polyurethane energy-saving panel, the product of the sandwich panel lines, is the polyurethane insulation sandwich panel for building. The product is a double-layer colour steel plate with polyurethane rigid foam as an insulation layer. It is usually used in the wall and roof enclosure system of industrial plants, logistics storage and integrated houses.

As a professional supplier in China, Jinggong offers PU sandwich panel production lines and rock wool sandwich panel production lines, contact us if you need them!

2. What is a PIR sandwich panel?

PIR sandwich panel, the product of PIR sandwich panel also known as polyisocyanate sandwich panel, is a foaming material made by reaction of isocyanate with polyether after the catalyst. Its physical and fire resistance are better than those of general polyurethane. It is an ideal organic low-temperature insulation material, which has small thermal conductivity, light shockproof and strong adaptability. It is widely used in oil refineries, chemical plants, ethylene, chemical fertilizer, cold storage and the construction industry.

3. The differences between PU and PIR sandwich panel

(1) Difference in fire resistance:

PU foam: generally B3 grade, by adding flame retardants, it can reach B2 grade.

PIR foam: generally B2 grade, by adjusting the concentration of polyisocyanurate acid ring and other formula technology, it can reach the B1 level, and the oxygen index can reach more than 35%.

(2) Difference in thermal insulation properties:

PU foam: the thermal conductivity is generally 0.022 to 0.026 W/mK (25 degrees Celsius).

PIR foam: thermal conductivity can be as low as 0.018 W/mK (25 degrees Celsius).

(3) Difference in bulk density:

PU foam: generally achieve 35-45kg/m3, in order to achieve satisfactory strength requirements.

PIR foam: generally achieve 45-55kg/m3, in order to achieve satisfactory strength requirements.

(4) Difference in temperature range:

PU foam: below 110 degrees Celsius.

PIR foam: it can reach 205 degrees Celsius.

(5) Difference in water absorption:

PU foam: generally 2.5 to 3%.

PIR foam: up to 0.9%.

The Failure and Solution of Wall Panel Machine

The feature of jinggong wall panel machine is that it adopts double drive twin roll extrusion process. The production process of the product is from sizing to main material, laying, compounding and re-pressing.

Wall panel machine equipment owns high-level automation, and its operation is relatively stable, its specifications can be arbitrarily adjusted. The surface of products produced by wall panel machine looks smooth and flat, and the density is also very high. It really realizes the industrial assembly line production of new building partition, reduces the cost and strength of production workers, and changes the old mode.

Any product in the use process will encounter many difficult problems or failures. Here are the basic wall panel machine failures or problems:

1. Leakage problem

If the wall panel machine is used for a long time, some parts of individual machinery and equipment may leak. There are many reasons for this problem, including the loosening or vibration of machine parts, the influence of machine heating, the problems of machine seals and pipe joints, etc. So we have to check the corresponding parts one by one to solve the problem in time.

2. Loosening problem

If the parts of wall panel machine have the deviation of geometry and fit size, they will be impacted and vibrated at the initial stage of use, and they will also be impacted by heating, deformation and other factors, resulting in very fast wear and easy loosening. So timely inspection and maintenance work is essential.

3. Motor problem

Poor lubrication of the motor may lead to the fact that the lubricating oil is not easy to form an average oil film on the friction surface of the equipment, resulting in wear. This is due to the small fit clearance of the parts of the new equipment, and it may also be due to assembly and other reasons, it is difficult to ensure the average fit clearance.

4. Human factors

It is not uncommon for operators to blindly operate the equipment according to regulations because of inadequate training or insufficient understanding of the equipment, which leads to product failure and affects product output and quality.

The Core Equipment of Automated Three-dimentiona

Tracked roadway stacking crane, a special crane developed with the appearance of three-dimensional warehouses, referred to as stacker crane. It is a very important lifting and handling equipment in a three-dimensional warehouse and a symbol of a three-dimensional warehouse. Its main purpose is to run along the track in the roadway of the high-rise warehouse to store the goods at the entrance of the roadway into the cargo compartment or to take out the goods in the cargo compartment and transport it to the entrance of the roadway to complete the warehouse operation.

There are many types of automated stacker cranes. In the current three-dimensional warehouse applications, the most common are the following two categories:

Ⅰ. Single-column structure and double-column structure divided by the structural form.

Ⅱ. Linear type and curved type divided by the running track.

 Regardless of the type, the stacker is generally composed of basic parts such as horizontal walking mechanism, lifting mechanism, loading platform, and fork mechanism, frame, and electrical equipment. The walking motor drives the wheels through the driveshaft to move horizontally on the lower rail. The lifting motor drives the cargo platform to move vertically through the chain/wire rope/belt. Telescopic movement is made by the fork on the loading platform. The walking addresser is used to control the horizontal walking position of the stacker. A lifting addresser is used to control the lifting position of the cargo platform. Computer control can be realized through address recognition, photoelectric recognition, and conversion of communication numbers, and automatic, semi-automatic, and manual control can also be realized through the control panel.

Currently, jinggong stacker cranes are widely used in industries such as machinery manufacturing, automobile manufacturing, textiles, railways, cigarettes, and medicine. With the development of modern industrial production, the technology of tracked roadway stackers is constantly improving and perfecting.
