Polyurethane rigid foam waterproof and thermal insulation integrated panels require maintenance. Although they have excellent waterproofing, insulation and durability properties, during long-term use, performance may still be degraded or damaged due to environmental factors, construction defects or external forces. The following is a detailed description from three aspects: the necessity of maintenance, maintenance content and maintenance cycle: 1. The necessity of maintenance to extend the service life. Although polyurethane rigid foam materials are resistant to aging, if exposed to ultraviolet rays, temperature changes or chemical corrosion environments for a long time, surface powdering, cracking or insulation performance degradation may occur. Regular maintenance can slow down the aging rate and extend the service life of the board. Maintain waterproof performance. If the waterproof layer is damaged due to construction defects (such as improper joint treatment) or external damage (such as mechanical impact), it will cause water seepage problems and affect the safety of the building structure. Maintenance can detect and repair leaks in time. Ensure the insulation effect. If the joints of the panels are cracked due to loose installation, thermal expansion and contraction, or the surface is contaminated (

For concrete walls and masonry walls, the base surface should be

In the field of architecture, exterior wall insulation and decorative integrated panels are increasingly widely used, among which polystyrene boards, extruded boards (usually what we call EPS boards) and hard foam polyurethane composite boards have become the three most popular mainstream insulation materials. So, what are the characteristics of these three materials and what are the similarities and differences between them? Next, we will analyze it in depth one by one. 1. Comparison of the characteristics of exterior wall insulation materials. Polystyrene board (EPS board) characteristics analysis. Polystyrene board is full of polystyrene foam board, and is often called foam board in daily life. It is made of polystyrene beads containing volatile liquid foaming agent, after heating and pre-transmission treatment, and then heated in a mold to finally form a white solid with a fine closed-cell structure. Advantages Overview: Excellent thermal insulation and thermal insulation: Polystyrene board has excellent thermal insulation performance, providing strong guarantee for building energy conservation. The process is mature and stable: its production system and technical process are quite mature, ensuring the product

The integrated polyurethane hard bubble insulation decorative panel has excellent energy-saving effect. Its core advantages are reflected in its extremely low thermal conductivity, waterproof and moisture-proof performance brought by high closed porosity, durability of thermosetting materials, and quality stability guaranteed by factory prefabricated processes. The specifics are as follows: 1. Low thermal conductivity and excellent thermal insulation performance. The thermal conductivity of polyurethane hard bubbles is 0.018-0.024W/(m·K), which is only 1/3 of traditional insulation materials (such as rock wool, EPS). This means that at the same thickness, its insulation effect is significantly better than other materials. For example, the construction thickness only needs 40mm to meet the national energy-saving requirement of 65%, while traditional materials may need to be thicker to achieve the same effect. This characteristic allows the thickness of the building exterior walls to be greatly reduced, indirectly increasing the indoor use area. 2. High closed cell rate, waterproof and moisture-proof performance, outstanding closed cell rate of polyurethane hard bubbles exceeds 90%, and some products even reach 9.

Polyurethane hard bubble waterproof and insulation integrated board is a new type of building material integrating waterproofing, insulation, structural support and other functions. Its core role is reflected in efficient insulation, reliable waterproofing, lightweight structure, convenient construction, etc. It is suitable for building roofs, walls, cold storages, industrial factories and other scenarios. The following is a specific analysis of the functions: 1. High efficiency insulation and heat insulation, reduce energy consumption, and low thermal conductivity. The thermal conductivity of polyurethane hard bubbles is only 0.022~0.028 W/(m·K), which is far lower than that of traditional insulation materials (such as polystyrene plate 0.039 W/(m·K), rock wool 0.035~0.045 W/(m·K)). This means that at the same thickness, the thermal insulation performance of polyurethane hard bubbles can significantly reduce heat exchange inside and outside the building and reduce the energy consumption of air conditioners, heating and other equipment. Continuous seamless insulation layer integrated plate forms a continuous insulation layer through on-site spraying or prefabricating process, avoiding the thermal bridge at the splicing of traditional materials.
