Several requirements to ensure the quality of polyurethane cold storage board
The quality of the polyurethane cold storage board is related to its steel plate thickness, foaming density, and production process. Below, Yanghu Refrigeration will introduce the specific requirements of these factors: 1. The thickness of the steel plate of the cold storage board: In general, the thickness of the color steel plate is more than 0.35mm, which is the most basic. If you have higher requirements, you can also choose thicknesses such as 0.4mm and 0.5mm! Color steel less than 0.35mm will easily appear a lot of air bubbles on the surface of the board during the foaming process of the library board, which will affect the appearance. The minimum steel plate requirement for Yanghu Refrigeration in Changzhou City is 0.376mm, and users can purchase it with confidence. 2. Cold storage board

How to remove the odor in the cold storage?
Users who use refrigerators know that the refrigerator will have an odor after a long time, and the same will happen in the refrigerator. In fact, the odor of the cold storage is that the cooking raw materials and food in the cold storage produce an abnormal smell through physical and chemical changes under the influence of external factors. Over time, the odor sticks to the walls, ceiling, and equipment and tools of the refrigerator. There are several reasons for the peculiar smell: 1. There is a peculiar smell in the cold storage before the food is put into it. Before the food is put into the cold storage, there is a phenomenon of spoilage, such as spoiled eggs, meat, fish, etc. 2. Cold storage where fish has been stored, and meat, eggs, or fruits are stored without cleaning

Classification of cold storage
Many people know about cold storage, but they do not know that there are many classifications of cold storage, and its classification represents its main function. Now we mainly take a look at the types of cold storages that are divided according to the area. Generally, it can be divided into three categories: storage cold storage, retail cold storage, and production cold storage. Productive warehouses are generally built in areas that are close to the source of goods or where the sources of goods are concentrated. The main function is to cooperate with retail cold storage for short-term cold storage. Retail cold storage is generally a kind of cold storage used by residential areas or enterprises to directly serve consumers. The main features are small storage capacity, many varieties, and low stocking rate. The storage-type cold storage mainly considers the capacity of the cold storage, making it longer

The performance advantages of polyurethane exterior wall insulation board
Polyurethane sandwich panels are used as building insulation materials. Polyurethane rigid foam breaks the single function of traditional building materials—waterproof is not insulated, and thermal insulation is not waterproof. Once the waterproof layer leaks, the insulation layer will lose its insulation function. Compared with other single-function thermal insulation or waterproof materials, polyurethane rigid foam has obvious advantages: 1. Polyurethane rigid foam has a multi-purpose function, and has many functions such as heat preservation, waterproofing, sound insulation, and vibration absorption. 2. Excellent thermal insulation performance, it is the thermal insulation material with the lowest thermal conductivity (≤0.024) and the highest thermal resistance value among all building materials in China at present, and the thermal conductivity is only half of EPS foamed polystyrene board.
