Shandong Bangyuan New Building Materials Co., Ltd. has found that with the recent cooling of the climate and the decreasing temperature, the construction of external wall insulation projects is facing greater challenges. The quality of external insulation projects directly affects system performance and even residents' safety. Below is the key to building external wall insulation materials in winter.
Top the list, do a good job in quality monitoring. From checking planning drawings to determining plans, every step should avoid generalizing and blindly learning. Scientific and reasonable planning requires data support from geological and other conditions surveys at the beginning of the planning process. During this process, the insulation materials that can be used in the project are determined through comparative analysis of relevant data. At the beginning of planning, it should be ensured that the selected materials are suitable for the climate, geology, and other conditions of the building and its area.
Due to the complementary nature of each link, if quality monitoring is not strict enough, resulting in gaps in individual links, it may affect the final construction effect. As long as quality monitoring is carried out throughout the entire process to ensure that the external wall protection data of the building can truly play a protective role and reduce unnecessary loss before and after construction.
In winter with a relatively cold climate, in order to ensure construction quality, special attention should be paid to following the seasonal construction plan of external wall insulation materials. There are many projects that have not been strictly implemented, resulting in construction quality not meeting the requirements, mainly reflected in the following aspects. (1) Failure to pay close attention to climate forecasts at all times, and insufficient preparation due to temperature changes, resulting in problems with concrete pouring and maintenance; Or blindly adjusting the process arrangement, not considering carefully, and burying quality hazards. (2) The product protection is not in place, the insulation operation does not meet the requirements, and there is not enough cotton felt to cover it. According to the requirements, cotton felt should be prepared in advance for covering, and the storage temperature should not be lower than 5 ℃, and all powder materials should be stored in a dry place. (3) In cold weather, improper control of Water–cement ratio of concrete and uneven vibration will lead to unsatisfactory concrete quality. According to the requirements, the Water–cement ratio and glue cement ratio should be used within the rule range. Do not mix the materials too thinly, otherwise the setting time will be prolonged. It is prohibited to soak the grid cloth in water to prevent the grid cloth from freezing. At the same time, the plastering construction should be carried out at noon as far as possible to reduce the impact of temperature fluctuations.
Thirdly, the operations of construction personnel should be strictly carried out in accordance with the disclosure content of the external insulation data system. If a single person has poor construction habits, is blind and confident, does not operate according to requirements, and does not pay attention to the operation process and related details of the external insulation data, it is likely to cause minor losses and major disasters.
Ensuring the construction quality of external wall insulation materials is a systematic project that requires quality supervision from the source and does not overlook any small areas that may present safety hazards and quality issues in order to pass the winter with peace of mind.

Construction process and precautions of adhesive powder polystyrene particles

Rubber powder polystyrene particle insulation mortar is composed of rubber powder and polystyrene particles. The two materials are packaged in separate bags and mixed with water in proportion (rubber powder 1:2). The material should be used up within 4 hours after mixing.

Characteristics and construction points of polymer bonded mortar

Many customers do not have a special understanding of the characteristics and construction points of polymer bonded mortar. In this issue, Shandong polymer bonded mortar manufacturer will come to chat with you about the characteristics of our products.

What are the main properties of graphite polystyrene board?

Graphite polystyrene board insulation: Graphite polystyrene board EPS polystyrene board mechanism rock wool mortar composite board. Hydrophobic rock wool board is a thermal insulation layer material, which is connected and fixed to the base wall using adhesive and nail bonding technology. It is a Class A non combustible building energy-saving insulation system composed of a plastering layer composed of plastering adhesive and reinforced glass fiber mesh cloth, as well as a decorative mortar facing layer or coating.

The main properties of graphite polystyrene board

Graphite polystyrene board has the same effect and lower cost. The outstanding insulation ability of the insulation board is particularly evident at low density. It is more cost-effective than using conventional EPS insulation boards. High cost-effectiveness, compared to other fire-resistant insulation systems, it is more cost-effective when achieving the same effect.

System characteristics and application scope of external wall insulation board

The external wall insulation board can be used separately for wall insulation using mechanical anchoring method, or can be used for external wall insulation by combining with other insulation materials.
