Characteristics of cold storage insulation materials

冷庫房圍護系統節能保溫隔熱材料產品在保溫節能、低吸水環保等性能指標及質量安標準逐步提高，對于冷庫圍護系統節能保溫材料生產企業在技術投入、研發能力、工藝等方面提出了更高的要求。

The performance indicators and quality safety standards of energy-saving thermal insulation materials for the enclosure system of cold storage room have been gradually improved in terms of energy conservation, low water absorption and environmental protection, and higher requirements have been put forward for the manufacturers of energy-saving thermal insulation materials for the enclosure system of cold storage room in terms of Technology investment, R & D capacity, process, etc.

冷庫作為冷鮮食品的儲存心，在環保方面有更多的要求。所需板材不僅要使用新型環保材料，還要采用環保發泡技術進行加工生產， 同時，遵循國際標準和國家倡導，采用環保阻燃劑，不含HBCD，使食品接觸更安，滿足可持續發展的要求。

As the storage center of cold and fresh food, cold storage has more requirements on environmental protection. The required plates should not only use new environmentally friendly materials, but also adopt environmentally friendly foaming technology for processing and production. At the same time, in accordance with international standards and national advocacy, they should adopt environmentally friendly flame retardants without HBCD, so as to make food contact safer and meet the requirements of sustainable development.

冷庫擠塑板優勢

Advantages of cold storage extruded board

冷庫專用擠塑板具有良好的抗水蒸氣滲透和抗壓性能，在建筑冷庫中的應用具有特殊的優勢，可應用于各個部位。應用于樓地面，內外墻體屋頂或吊頂等。

The special extruded board for cold storage has good resistance to water vapor penetration and compression resistance. It has special advantages in the application of building cold storage and can be applied to various parts. It is applied to floors, internal and external walls, roofs or ceilings, etc.

在冷庫中使用冷庫專用板的主要優點包括：

The main advantages of using cold storage dedicated boards in cold storage include:

1、長期保溫效果

1. Long term insulation effect

冷庫專用擠塑板保溫效果持久在-20℃時達到0.025W/M·K。

The insulation effect of special extruded board for cold storage can reach 0.025w/m · K at -20 ℃.

2、耐久性

2. Durability

冷庫專用擠塑板的保溫性能隨時間變化小，保留率達90%以上。同時具有耐腐蝕性，能保證產品各方面的長期穩定性。

The heat preservation performance of extruded board for cold storage has little change with time, and the retention rate is more than 90%. At the same time, it has corrosion resistance and can ensure the long-term stability of all aspects of the product.

3、抗水性能

3. Water resistance

冷庫專用擠塑板吸水率低于0.5%，水蒸汽透濕系數小于3mg/(m·s·pa)。

The water absorption of the special extruded board for cold storage is less than 0.5%, and the moisture permeability coefficient of water vapor is less than 3mg/ (m · s · PA).

4、抗壓強度

4. Compressive strength

擠塑板是一種輕質、高強度的冷庫專用板材，根據設計要求，可選擇200 KPa適宜墻面安裝到1000 KPa以上具有不同抗壓強度的產品。

Extruded board is a kind of light and high-strength special plate for cold storage. According to the design requirements, products with different compressive strength can be selected from 200 kPa suitable for wall installation to more than 1000 kPa.

5、抗凍融性能

5. Freeze thaw resistance

實驗室做過200次(-45℃到20℃)凍融試驗。結果非常好，無論是導熱系數、吸水率還是抗壓強度均沒有大變化。

The laboratory has conducted 200 freeze-thaw tests (-45 ℃ to 20 ℃). The results are very good, and there is no significant change in thermal conductivity, water absorption or compressive strength.

6、綠色環保性

6. Green environmental protection

該工藝采用環保CO2發泡工藝，在使用過程中不揮發有害污染物質。

The process adopts environmental friendly CO2 foaming process, which does not volatilize harmful pollutants during use.

7、尺寸穩定性

7. Dimensional stability

冷庫專用擠塑板發泡充足，閉孔率高達99%，使原料與發泡劑充分反應，達到尺寸穩定性，能長期保證板材變形小。

The special extruded board for cold storage has sufficient foaming, and the closed cell rate is as high as 99%, so that the raw materials can fully react with the foaming agent, achieve dimensional stability, and ensure small plate deformation for a long time.
