Recently, some authoritative experts in China have proposed establishing guidelines for foam glass insulation boards, primarily because, in some regions, there has been chaos in the market for foam glass insulation boards. Experts analyze that some building fires are not only related to exterior insulation materials but also intricately linked to construction management, material management, safety management, and construction procedures.Previously, relevant departments had made decisions regarding new fireproof foam glass insulation boards. However, many manufacturers of foam glass insulation boards were affected, facing obstacles in their sales. Due to the lack of unified standards for some new types of external insulation materials, companies created their own enterprise standards, but the time for standard filing is generally prolonged, which can hinder production.Foam glass is used as wall insulation material, replacing red bricks, reducing wall thickness, and saving energy, which indirectly expands the usable area while decreasing the self-weight of the building. When installed, regular cement mortar or polymer cement mortar is used for adhesion, providing strong bonding. If used as an external wall coating, simply apply a layer of cement mortar over the foam glass layer for leveling. If using colored foam glass, it can be cut into specific shapes, directly bonded with polymer cement mortar.Foam glass insulation bricks can be adhered to walls or ceilings using adhesives, leveled, and then painted with decorative coatings. Wood wool boards can also serve as insulation layers. Wood wool boards act as sound-absorbing materials and are often seen on theater and cinema walls. However, this material is relatively expensive and is suitable when rooms require both insulation and sound absorption. Alternatively, battens can be installed on the wall, filled with insulation materials such as mineral wool, and then covered with gypsum boards. This method requires tight coverage to prevent dust leakage.

Due to the wide variety of foam glass boards available on the market, users may face some confusion when selecting products. Therefore, as a manufacturer of foam glass, Henan Huitong provides an explanation of the characteristics of its products to help everyone select better foam glass.When selecting foam glass, consider the following aspects:1. Good foam glass should have a low thermal conductivity coefficient. The thermal conductivity coefficient is an important reference factor for determining the quality of foam glass; the lower the coefficient, the less energy will be transmitted through the material, resulting in better insulation performance.2. It should have good sound absorption properties, which depend mainly on the density per unit area; the higher the density, the better the sound absorption. 3. Good foam glass should have low hygroscopicity; as most insulation materials lose their insulating properties after absorbing water, since water has a high thermal conductivity coefficient. 4. Good glass boards must possess high strength to support their own weight. Thus, when purchasing foam glass boards, refer to the above aspects to choose ** quality products. Henan Huitong specializes in the production and sale of insulation materials, providing higher cost performance.

Types of Foam GlassEveryone knows glass, but not everyone is familiar with foam glass. The foam glass produced by Henan Huitong Insulation Materials Co., Ltd. is a porous inorganic non-metallic material made from crushed glass that is foamed and formed at high temperatures.★By usage: Insulating foam glass, sound-absorbing foam glass.★By raw materials used: Ordinary foam glass, quartz foam glass, lava foam glass.★By color: White, brown, yellow, pure black, etc.★By shape: Flat (code P), pipe (code G).★By density: ≤150kg/m³ (code 150), 151-180kg/m³ (code 180).Henan Huitong Insulation Materials Co., Ltd. mainly produces new green environmentally friendly energy-saving materials, with main products including foam glass series products, mortar series, and chimney corrosion-resistant acid-resistant glue series products, covering industries such as green energy-efficient buildings, Sinopec, and power plants. We are a large modern enterprise integrating production, sales, and service.

Henan HuitongFoam Glass Shell is a new type of environmentally friendly equipment material. Let\'s learn about it today!Henan Huitong's foam glass shell is a closed-cell foam glass and is considered a good insulation material. It has many advantages including lightweight, low thermal conductivity, moisture resistance, low water absorption, non-combustibility, resistance to mold, high mechanical strength, easy processing, chemical corrosion resistance (except hydrofluoric acid), non-toxicity, and stable performance.Henan Huitong’s foam glass shell serves as both a cryogenic material and an insulation material, able to adapt to a wide temperature range from deep freezing to higher temperatures. Its significant value lies not only in its durability over years without deterioration but also in its fire and shock resistance. In harsh environments with low temperatures, deep freezes, underground projects, flammable and explosive conditions, humidity, and chemical corrosion, it is not only safe and reliable but also durable, earning the title of "insulation material that doesn’t need replacement." Therefore, it is widely used in residential construction, petroleum, chemical, underground projects, shipbuilding, and national defense industries.If you are interested in this material, you can visit Henan Huitong Insulation Materials Co., Ltd.

Manufacturing Process of Foam Glass.The manufacturing process of foam glass mainly includes three parts: 1. Preparation of foam glass mixture;2. Molding of the powder body; 3. Preheating, sintering, foaming, stabilizing bubbles, and annealing. ★ PreheatingThe purpose of preheating is to remove any chemically bonded water, adsorbed water, and free water present in the mixture; as the powder body has poor thermal conductivity, directly heating sintering at high temperatures can cause surface carbon to oxidize, leading to uneven foaming. Therefore, a temperature within the range of 350-400 degrees is typically selected for preheating to eliminate various moisture in the body. The preheat temperature used in this experiment is 400 degrees. ★ Sintering and FoamingThe preheated body is quickly heated to the predetermined sintering temperature and held for a certain time. By rapidly increasing the temperature, the foaming agent decomposes, and the gas produced by the foaming agent gets trapped in the softened body without escaping, resulting in a significant amount of gas phase. The heating rate during the sintering process is generally selected at 8-10 degrees/min. ★ AnnealingAfter foaming, the samples are rapidly cooled to the desired annealing temperature at a fast cooling rate, generally 15-20 degrees/min. Rapid cooling fixes the generated porosity structure within the material to form a porous structure. As the samples experience stress during rapid cooling, it is necessary to hold the samples at temperature for a period to eliminate stress; after annealing, the furnace power is turned off and the samples are allowed to cool to room temperature naturally.

Construction Precautions for Foam Glass Boards1. Use special adhesives to seal the gaps and joints for different specifications of foam glass boards.2. All parts of the products used need to meet the required thickness, otherwise, many problems will occur later.3. Be careful when adhering colored foam glass boards, do not apply too much force, and all joints and gaps should be bonded gently.4. Follow a specific sequence when installing foam glass boards based on the principle of starting from large to small, and bending before straightening.5. When constructing refrigeration equipment, ensure the bonding width is not the same as the material's thickness.6. When installing foam glass board covers, ensure no gaps are left.7. After installation, the system cannot be turned on for the next 36 hours.8. Regardless of the type of foam glass board, the price may become elliptical due to packaging, and when cutting open, it should be done along the flatter side.
