Selection of raw materials when shelves are used in cold storage

The choice of raw materials when the shelves are used in cold storage. Now the development of cold chain logistics is getting faster and faster. Cold storage also needs to store the goods. This also needs to be used on the shelf. Because the environment in the cold storage is more special, the use environment of the shelves is also different. There are some differences in the choice of materials for the shelf factory when it comes to the production of cold storage shelves and ordinary types of shelves. The purpose is to make the shelf use better in the cold storage.


Literally, there is a “cold” word, which looks basically the same from the outside, but from the material point of view they are definitely different, because the cold storage is relatively humid and the temperature is relatively low, the humidity is relatively high, so the shelf requirements are also High, we must first use a relatively high shelf, that is, three-dimensional, because the cold storage temperature is very low, which is a test of the shelf, shelf material to use better tough materials, can not rust, which in the process The upper requirements are higher, especially the use of double-layer anti-rust and antifreeze.

The shelf factory will strictly select the raw materials for the shelves in the cold storage. In the shelf production, commonly used carbon structural steel Q235 includes Q235A, Q235B, Q235C, Q235D, and Q235E. These marked steel models are mainly characterized by their ability to adapt to different temperatures. A refers to normal temperature adaptability without impact, B is above 20°C, C is above 0°C, D is above -20°C, and E is Above -40°C. Therefore, before the production of cold storage shelves, the supply and demand sides should understand how much temperature is reached in the warehouse in use, so as to determine and select their own materials to design and produce the most appropriate cold storage shelves.


The carbon structural steels A/B/C/D also have different trace element contents, with higher quality grades and better performance at low temperatures. In general, Q235D will be used as the main material of cold storage shelves.

In order to allow better use in cold storage, shelving factory will perform certain treatment on the surface of the shelf. Finally, the powder used for surface treatment is made of high-quality polyester epoxy powder, and its corrosion resistance and cold resistance are higher than those of the country. Standards related indicators, after processing parts surface smooth, smooth, strong coating adhesion, beautiful appearance.

In the process of development, shelving factory is still constantly improving the production technology of shelves, producing shelves that meet the quality requirements, satisfying the conditions when shelves are used in cold storage, so that quality can be guaranteed, and enterprises will be more assured when using them.

Basic Peristaltic Pump

The main factors that need to be considered when using a basic Peristaltic Pump include the compatibility of the liquid with the Peristaltic Pump Tubing used, the trade-off between flow rate and pulse rate(roller number), Each rotation will dose equal liquid volume which ensures the flow accuracy. and the roller number decides the pulsation of the liquid, if you need a low pulsation liquid delivery, pls choose the multiple rollers to pump head or work with the Pulsation damper.
The basic peristaltic pump with a simple display and easy knob control, which can meet the liquid constant transfer industrial cases. For example: food/cosmetic/beverage/checmical additive feeding. transfer the liquid from a big tank to the small tank, liquid circulation..etc.
