200mm Cold Storage Sandwich Panel

Features:

●Through prestaging the special airtight rubber in wedge-shaped structure between internal and external layer of PNS Brand cold storage panel, so that the adjacent panel of the inner and outer layers of cold steel as one organic,greatly overcome the thermal expansion and contraction phenomenon of cold storage panel,make the whole air tightness performance is equivalent to the effect of seamless steel plate welding .

●Light weight and beautiful appearance, the assembly board can be disassembled and reinstalled in another place is easy and fast.

Advantages:

1. Hard polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35~ 40kg/m³, the thermal conductivity is only 0.018g~0.023w/(m.k), which is equivalent to about half of EPS, which is the lowest thermal conductivity of all insulation materials.

2. Polyurethane cold storage sandwich panel has moisture-proof and waterproof properties. The closed pore rate of rigid polyurethane is more than 90%, which is a water-repellent material, which will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water.

3. Polyurethane cold storage sandwich panel fireproof, flame retardant, high temperature resistance. Polyurethane, after the addition of flame retardants, is a flame-retardant self-extinguishing material, its softening point can reach more than 250 degrees Celsius, and it will only decompose at higher temperatures: In addition, polyurethane will form ash on the surface of its foam when burned, which helps to isolate the foam underneath. It can effectively prevent the spread of fire. Moreover, polyurethane does not produce harmful gases at high temperatures.

Parameters of 200mm cold storage sandwich panel:

Allowable vertical load, span and heat transfer coefficient of PNS’ 200mm cold storage sandwich panel (allowable deformation≤L/200):

Above core material :PU (40-42KG/M3 )

Development Background:

With the update of refrigeration technology. The tentacles of cold storage engineering have penetrated into more fields. It has developed in the fields of chemical raw materials, pharmaceuticals, scientific research, cold drinks, flowers, green plants, tea, drugs, electronic instrumentation, mushroom cultivation, air conditioning library, logistics, etc. The deeper the tentacles of refrigeration technology in various fields, the more the number of cold storage needs is increased to a certain extent. The increase in the number of cold storages has brought about the increasing demand for cold storage panels.

Introduction:

Meat freezer storage of meat food is a scientific method of preservation. Meat freezing and refrigeration technology is to cool food at different temperatures and frozen food in different temperatures in the cold storage for short-term or long-term reserves, mainly suitable for a variety of meat, aquatic products and other food storage.

Features:

Due to the influence of weather temperature, meat food may deteriorate due to the decomposition of food enzymes, oxidation and microbial growth and reproduction. The low temperature of the meat cold storage can control the decomposition of enzymes, slow down oxygen, inhibit the growth and reproduction of microorganisms, significantly slow down the chemical change rate of meat food, and maintain the original quality after weeks to months of product production, and the refrigeration of meat food below -18 ° C can make the effect of microorganisms and enzymes on food become weak, below -23 ° C Low temperature can greatly extend the shelf life, and the refrigeration period at -30 °C is more than twice as long as the freezing period at -18 °C, of which pork is the most obvious.
