B1 Grade Polyurethane Rigid Foam Spray Combination Material For Building Interior Walls

The foaming agent of the B1-grade sprayed polyurethane rigid foam composite for interior building walls is an ultra-low thermal conductivity and environmentally friendly foaming agent. When the B1-grade polyurethane foam for interior walls is used in combination with WANNATE®2208, a foam product with excellent flame retardant performance can be obtained, and its combustion performance reaches B1 level (GB 8624 – 2012).

The B1-grade sprayed polyurethane rigid foam composite for interior building walls can be constructed on cement surfaces, brick surfaces, wood surfaces, and other substrates. It has strong adhesion and good product dimensional stability.

The product is applied to spray insulation fields such as cold storage, food factories, chemical plants, industrial buildings, and civil buildings (interior wall fields). The B1-grade sprayed polyurethane rigid foam composite for interior building walls is a fast-curing system that can bear loads immediately and meets the construction requirements of most spray insulation fields. Before using the B1-grade sprayed polyurethane rigid foam composite for interior building walls, tests must be carried out first to ensure the reliability of the composite system for use in specific projects.

(1) For the foaming of the B1-grade sprayed polyurethane rigid foam composite for interior building walls, the material temperature is required to be 25℃, the volume ratio of materials is 1:1, and manual mixing is carried out using an electric stirrer (2500r/min).
(2) Operate in accordance with the precautions in this document. The overall density of the foam product obtained by the high-pressure sprayer is greater than 45kg/m3.
(3) The values provided in this document are typical test values. Specific data may vary slightly due to environmental conditions. For our company’s products, the listed data has no legal binding force.

The construction equipment for the B1-grade sprayed polyurethane rigid foam composite for interior building walls is a high-pressure sprayer. Before construction, please check and calibrate the conveying ratio of black and white materials and the mixing pressure of the high-pressure sprayer.

The spraying operation environment temperature should be 10 – 40°C, the wind speed should not be greater than 5m/s (level 3 wind), the relative humidity should be less than 75%, and construction is not allowed in rainy days. When the construction environment temperature is lower than 10°C, reliable technical measures should be taken to ensure the spraying quality.

During the spraying operation, control the temperature of the black and white materials entering the spray gun to be higher than 30°C, and ensure that the substrate is dry and clean. Control the thickness of each gun of foam within the range of 1 – 1.5cm (excluding the primer layer). During the construction, the next layer of spraying can be carried out only when the surface of the previously sprayed polyurethane rigid foam is no longer sticky. Other relevant standards shall be implemented in accordance with national standards. If the above conditions are not met, all responsibilities shall be borne by the buyer.

The spraying operation shall be carried out in accordance with GB 50404 – 2017 “Technical Specification for Rigid Polyurethane Foam Insulation and Waterproof Engineering”.

The construction site should be a fire – prohibited area, well – ventilated, away from fire sources, and smoking is strictly prohibited. When there is hot work nearby, the hot work approval system must be strictly implemented, and corresponding safety measures and special personnel supervision shall be carried out.

Before the formal construction of the project, the buyer must conduct tests in an environment consistent with the construction conditions to ensure the reliability of the composite system for use in this specific project. During formal construction, it is deemed that the buyer has recognized the qualified performance inspection of the product. If the above operations are not followed, all responsibilities shall be borne by the buyer.

The composite should be stored in a sealed container to avoid absorbing water vapor. Therefore, during storage and transportation, it is necessary to ensure that the container is dry and sealed.

The B1-grade sprayed polyurethane rigid foam composite for interior building walls should be stored in a sealed manner at a room temperature between 5 – 35°C in a well – ventilated and cool place, avoiding direct sunlight or long – term storage above 40°C to prevent a large amount of foaming agent from volatilizing, affecting storage and product performance.

Under suitable storage conditions, the shelf life of the B1-grade sprayed polyurethane rigid foam composite for interior building walls is 6 months. After 6 months, it can be used continuously after passing the inspection.

Direct contact with the B1-grade sprayed polyurethane rigid foam composite for interior building walls can cause moderate eye irritation and mild skin irritation, and may cause skin allergies. Repeated inhalation of high – concentration vapors can cause respiratory allergies. Seek medical attention immediately and take anti – inflammatory, anti – allergic and other symptomatic treatment measures.

During operation, be careful to prevent direct contact with the skin and splashing into the eyes. Please wear necessary protective equipment (gloves, safety glasses, work clothes, etc.).

Once it splashes onto the skin or into the eyes, immediately rinse with clean water for at least 15 minutes, wash the skin with soapy water, and seek medical attention if necessary. In case of ingestion, seek medical attention immediately for symptomatic treatment.

This product is not a flammable liquid, explosive, oxidizer, corrosive, toxic, or radioactive hazardous material during storage and transportation, and it is not a hazardous product.

Fire – fighting Media: Carbon dioxide, foam, or chemical dry powder fire extinguishers can be used for fire – fighting. When there is no other fire – fighting agent, a large amount of fog – like water can be sprayed. Once the fire is extinguished, the spilled materials should be cleaned up (see the Leakage and Spillage Handling section).

Fire – fighting Procedures: Normal protection.

Small amounts of leaked and spilled materials can be washed away with water. In case of a large leak, collect and recycle it, and wash the contaminated ground with water or detergents. The disposal of waste composite must comply with local government environmental protection regulations.
