概述聚氨酯岩棉板在冷库使用中的优点

聚氨酯岩棉板广泛应用于冷库、绿色、环保、节能、健康等领域。在冷库中广泛使用聚氨酯岩棉板的优点是：
1.轻质聚氨酯泡沫塑料被用作冷藏板的衬里材料。聚氨酯岩棉板具有保温性能好的优点。外墙Pu由SII、PVC彩钢板和不锈钢板组成。本实用新型的优点是防止内外温差过大引起的温度扩散，从而节约能源，提高冷库的工作效率。

2. 聚氨酯岩棉板具有耐火、阻燃、耐高温等特点。添加阻燃剂后，聚氨酯岩棉板成为软化点大于250的阻燃自熄材料，只有在高温下才会分解。此外，当聚氨酯岩棉板燃烧时，泡沫表面将形成灰，以帮助隔离下面的泡沫。它能有效防止火势蔓延。聚氨酯岩棉板在高温下不会产生有害气体。
3.由于 聚氨酯岩棉板具有优良的保温性能，在相同的保温要求下，可以减少建筑外保护结构的厚度，增加室内使用面积。
4.抗变形能力强，无开裂，表面光滑、稳定、安全。聚氨酯具有稳定的孔结构和基本封闭的孔结构。聚氨酯岩棉板不仅具有优异的保温性能，而且具有良好的抗冻吸声性能。在正常使用和维护后，硬质泡沫塑料保温结构的使用寿命可长达30年。在结构的使用寿命期间，聚氨酯岩棉板的单价高于其他传统保温材料在干燥、潮湿或电化学腐蚀的正常使用条件下的单价，但增加的成本将被加热和冷却成本的大幅降低所抵消。

Polyurethane rock wool board is widely used in cold storage, green, environmental protection, energy saving and health. The advantages of widely using polyurethane rock wool board in cold storage are:

1. light polyurethane foam is used as the lining material of cold storage board. Polyurethane rock wool board has the advantage of good thermal insulation performance. The outer wall Pu is composed of SII, PVC color steel plate and stainless steel plate. The utility model has the advantages of preventing temperature diffusion caused by excessive internal and external temperature difference, so as to save energy and improve the working efficiency of cold storage.
2. Polyurethane rock wool board is fire-resistant, flame retardant and high temperature resistant. After adding flame retardant, polyurethane rock wool board becomes a flame retardant self extinguishing material with a softening point of more than 250 and will decompose only at high temperature. In addition, when the polyurethane rock wool plate burns, the surface of the foam will form ash to help isolate the foam below. It can effectively prevent the spread of fire. Polyurethane rock wool board will not produce harmful gas at high temperature.
3. Due to the excellent thermal insulation performance of polyurethane plate, under the same thermal insulation requirements, it can reduce the thickness of building external protection structure and increase the indoor use area.
4. Stong deformation resistance, no cracking, smooth, stable and safe surface. Pu has stable porous structure and basically closed pore structure. Polyurethane rock wool board not only has excellent thermal insulation performance, but also has good frost resistance and sound absorption performance. After normal use and maintenance, the life of the insulation structure with rigid foam plastic foam insulation can last up to 30 years. During the service life of the structure, the unit price of polyurethane rock wool board is higher than that of other traditional thermal insulation materials under the normal service conditions of dry, wet or electrochemical corrosion, but the increased cost will be offset by the greatly reduced heating and cooling cost.
