Insulated Wall Panel for Cold Storage

Product Introduction:

The core material of the sandwich panel in the cold storage is polyurethane/PIR, and the upper and lower sides are color steel plates or stainless steel plates. Generally, stainless steel is used as the surface in the food industry. In particular, 304 stainless steel of food grade is commonly used on the pu cold room panel of food factory. The insulation effect mainly depends on the thickness of the puf panel for cold room, the refrigeration equipment and the quality of the installation and construction. The thickness of insulated wall panels for cold storage is 50-250 mm.

Introduction to thermal insulation core material PUR/PIR:

PUR production line adopts European multi-component online process adaptive control technology and unique aerated mixed casting technology to realize online adjustment of process parameters and formulas according to environmental changes, so that the raw materials are mixed more fully and uniformly, the foam is more delicate, and the surface flatness and bonding strength of the panel are greatly improved, so as to ensure the production of different high-strength, energy-saving, different types and flame retardant grades of green environmental protection and energy-saving pu cold room panel.

Polyisocyanurate is referred to as PIR, and the PIR manufacturing process is to add an overdose of isocyanate esters to produce PUR based on specific process conditions The trimerization reaction occurs by itself to form a carbon-nitrogen six-link ring structure with better thermal stability, which makes the polyurethane foam more cross-linked to each other microscopically, enhances the strength of the cell wall, and appears to be dense and strong.

Features and advantages of pu cold room panel:

■The Concave and convex groove structure has improved the insulation and airtight of the puf panel for cold room, designed for refrigerated rooms and warehouses;

■The insulated wall panels for cold storage are uniform and stable, thermal insulation performance, good waterproof performance;

■Self weight is light, beautiful appearance, and effectively solve the temperature difference between refrigeration industrial;

■The body of cold storage can be freely changed in three places in three, width, and high. It can be expanded or reduced according to needs. It can also be removed from the assembly board, reinstalled in different places, and installed simple and fast.

The following is the introduction of several cold storages:

1.Cold storage room:

Cold storage room is mainly used for the refrigeration of food. Irregularly put part of the food into the cold storage, while at the same time irregularly take out another part of the food, there is no specific requirement for the refrigeration time of the food, and the library temperature is maintained in the range of -15 ° C ~ -18 ° C.

2.Mushroom storage:

Edible mushrooms are rich in a variety of amino acids, carbohydrates, vitamins, etc. needed by the human body, and are extremely valuable "green and healthy foods". As the demand for edible mushrooms increases, so does the demand for mushroom storage. Since 2006, it has built mushroom warehouses with a total area of 50,000 square meters in central cities such as Beijing, Shenzhen, Shanghai, Tianjin, Wuhan and other central cities, and the quality has reached global standards and is trusted by customers.

3.Chemical explosion-proof cold storage:

Chemical explosion-proof cold storage adopts the leading multi-functional microelectronics integrated explosion-proof device and optimized explosion-proof technology, and adopts all-optical isolation microwatt-level safety control circuit, with multiple safety protection functions, equipped with high-precision pressure and temperature detection system.

Chemical explosion-proof cold storage is assembled by explosion-proof units, explosion-proof coolers, explosion-proof control boxes, explosion-proof lighting, fireproof library plates and other special equipment, with reliable work, good maintainability, with limited maximum surface temperature, abnormal airtight leakage shutdown protection and other functions, good safety performance.

Chemical explosion-proof cold storage is mainly used for explosive gas storage, chemical and pharmaceutical electronic products raw materials and other constant temperature storage. It is generally divided into two levels: II.A, II.B and II.C.

Features of chemical explosion-proof cold storage:

The cold storage refrigeration system can make the warehouse adjust the use in the range of -15 °C ~ -25 °C in the ambient temperature. Since the items placed in the warehouse are flammable and explosive, all electrical treatment of the equipment is carried out at class II.C. Make the equipment safe and reliable, and set up a backup unit to ensure that the temperature of the cold storage can always be maintained at the low temperature condition required by the item.
