Introduction to Plaster      Plaster is a commonly used building material for wall decoration. Plaster powder serves two purposes when decorating walls: one is to fill gaps in wall surfaces, and the other is to create a refined finish. These two uses require different types of plaster powder and different application methods.Plaster is made from plaster of Paris as the basic material and polymer materials as the binding agent, combined with inorganic fillers through dry mixing. It is a new type of improved interior wall finishing material, which changes the traditional habit of using cement-based binding materials and ensures good compatibility and adhesion with various base walls. The quality of plaster application directly influences the safety, usability, and reliability of the building structure.Note:1. Choose an appropriate trowel; the size of the trowel should be proportional to the width and thickness of the plaster line being produced. Wider and thicker lines require more plaster powder, hence a larger trowel should be used. Add clean water to the trowel and then add in plaster.2. Pour the mixed plaster into the mold, quickly rotate the mold to evenly coat the plaster, until it stops flowing out of the mold.3. Demolding: Once the plaster is dry, place the plaster item on a flat surface, remove the clamps first, then gently peel away the mold from the bottom. (When demolding, ensure your hands face inward towards the mold; if there are hard-to-demold areas, pour some warm water on the outer surface of the mold to soften it before demolding).4. Sealing the base: Find a sheet of glass, ceramic tile or marble slab to prepare. Pour the prepared plaster into the mold, quickly cover the bottom with the board, then stand it upright. After 5-10 minutes, remove the glass tile or marble slab, and then remove the remaining plaster.

Construction Precautions for Foam Glass Boards1. The teams conducting on-site construction and the personnel involved must hold valid certifications, undergo training before starting work, and maintain strict production awareness to ensure quality.2. Foam glass board external wall insulation construction must take fire precautions to eliminate hazards at the earliest stage.3. The material management responsible person must strictly control all types of external wall insulation materials entering the site.4. The team responsible for the on-site construction of foam glass boards must formulate a detailed construction process plan and technical requirements. At least one week before the construction of external wall insulation, the technical head of the construction team must thoroughly train the on-site workers in both ** construction techniques and provide the client with a detailed technical disclosure plan, ensuring workers understand the technical requirements and strictly follow regulations during construction.5. During construction of thin plaster external wall insulation for foam glass boards, the Beijing External Wall Insulation Engineering Association recommends proceeding after the base wall has been verified and accepted by the Quality Supervision Bureau.6. During construction, the seams of the external wall insulation system must be properly sealed. Corners and other areas should receive special treatment to prevent deformation.7. Pay attention to the impact of weather during construction; work is generally permitted only under low humidity conditions. If humidity is excessive, a primer must be applied to the base surface.

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.

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.

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.
