The secret of PVC Celuka board composition

PVC Celuka board is a rigid foam board with high density, strength, and weather resistance, typically used in advertising signs, display boards, indoor and outdoor decoration, furniture, wall protection, and other fields. The name “Celuka” comes from the technology used in its production, which involves compressing bubbles inside the material through a special process, resulting in a denser and more robust surface. Due to its high density and weather-resistant properties, PVC Celuka board is generally more durable than traditional foam boards and can be used in a wider range of applications. In addition, PVC Celuka board is made of polyvinyl chloride (PVC), which means it has excellent properties such as waterproof, fire-resistant, and chemical corrosion resistance. These characteristics make PVC Celuka board a popular choice for building and advertising materials.

PVC Celuka board

The main ingredient in PVC Celuka board is polyvinyl chloride (PVC), which typically includes stabilizers, plasticizers, fillers, pigments, and other additives. The proportion of each ingredient in PVC Celuka board is usually determined by the manufacturer based on specific product performance requirements, and may vary depending on different products, production processes, product specifications, and environmental standards. Generally, the composition ratio of PVC Celuka board can be roughly divided into several categories:

PVC (50-80%),

fillers (5-40%),

plasticizers (5-25%),

stabilizers (1-5%),

pigments and other additives (0-10%).

It should be noted that these ratios are for reference only, and specific ratios may vary due to production processes, product specifications, environmental standards, and other factors. The PVC content in PVC Celuka board can affect its physical properties, chemical stability, and processing performance. Generally, the higher the PVC content, the better the physical properties and chemical stability of the PVC Celuka board, but it may also affect its processing performance. Different PVC contents in PVC Celuka board may affect its density, strength and stiffness, weather resistance, and processing performance. Therefore, customers can choose PVC Celuka boards with different PVC contents according to their specific needs to meet their requirements.

The content of calcium carbonate in PVC Celuka board is not explicitly mentioned in the above context. However, calcium carbonate is usually used as one of the fillers in PVC Celuka board to improve its hardness and density. Therefore, the specific content of calcium carbonate in PVC Celuka board may vary depending on the manufacturer, product specifications, and demand.

Generally, the content of calcium carbonate in PVC Celuka board is usually between 10% and 40%, and the specific ratio is determined by the manufacturer’s formula and production process. When using PVC Celuka board, different amounts of calcium carbonate need to be selected according to specific requirements to meet the needs.

What is the impact of different calcium carbonate contents on product performance?

Different calcium carbonate contents will have an impact on the physical properties, chemical stability, and processing properties of PVC Celuka board.

The following are the effects of different calcium carbonate contents on PVC Celuka board performance:

Density: As the content of calcium carbonate increases, the density of PVC Celuka board will also increase correspondingly.

Stiffness and hardness: Increasing the content of calcium carbonate can improve the stiffness and hardness of PVC Celuka board, making it more durable.

Durability: Increasing the content of calcium carbonate can improve the durability and wear resistance of PVC Celuka board, making it more durable.

Processing properties: As the content of calcium carbonate increases, the processing properties of PVC Celuka board will correspondingly decrease, making cutting and drilling more difficult.

Thermal stability: Calcium carbonate can be used as a substitute for stabilizers to improve the thermal stability of PVC Celuka board, making it more resistant to high temperatures.

It should be noted that different contents of calcium carbonate will have different degrees of impact on the performance of PVC Celuka board, and the specific impact will vary depending on factors such as the manufacturer’s formula, production process, and usage environment. Therefore, when choosing PVC Celuka board, the appropriate content of calcium carbonate needs to be selected based on specific needs and requirements.

What is the optimal ratio of PVC to calcium carbonate for improving the processing performance of PVC Celuka board?

The ratio of PVC to calcium carbonate has a certain impact on the processing performance of PVC Celuka board. Generally, the processing performance of PVC Celuka board is affected by the following factors:

PVC content: Increasing the PVC content will reduce the processing performance of PVC Celuka board because the hardness and brittleness of PVC will increase.

Calcium carbonate content: Increasing the content of calcium carbonate will increase the hardness and density of PVC Celuka board, thereby increasing the difficulty of processing.

Filler particle size: Changes in filler particle size will affect the processing performance of PVC Celuka board. Larger filler particle size will affect the surface quality and dimensional accuracy of PVC Celuka board, while smaller filler particle size will increase material costs and processing difficulty.

Processing conditions: Factors such as temperature, pressure, and processing speed will all affect the processing performance of PVC Celuka board.

Therefore, to improve the processing performance of PVC Celuka board, the appropriate ratio of PVC and calcium carbonate content needs to be selected based on specific application requirements. Generally, reducing the content of PVC and calcium carbonate and increasing the content of other additives can improve the processing performance of PVC Celuka board. At the same time, factors such as processing temperature, pressure, and speed need to be controlled during processing to achieve better processing results.

Which additive can be added to improve the processing performance of PVC Celuka board?

The processing performance of PVC Celuka board is not only affected by the content of PVC and calcium carbonate but also related to the content of other additives. The following are some common additives and their effects on PVC Celuka board processing performance:

Plasticizers: Adding plasticizers can improve the flexibility and processing performance

Density modifiers: Increasing the content of density modifiers can lower the density of PVC Celuka boards, making them easier to process.

Internal lubricants: Adding internal lubricants can reduce the viscosity and friction coefficient of PVC Celuka boards, thereby improving their processing performance.

External lubricants: Adding external lubricants can reduce the surface tension of PVC Celuka boards, making them easier to process and improving their surface smoothness.

Impact modifier: Adding a certain amount of impact modifier can increase the toughness and durability of PVC Celuka board, thereby improving its processing performance. It should be noted that different additives will have different effects at different levels, so it is necessary to select appropriate additives and levels based on specific circumstances. Additionally, different additives may interact with each other, so sufficient testing and adjustments are required to obtain optimal processing performance and product quality.

The proportion of each component in PVC Celuka board is usually determined by the manufacturer based on specific product performance requirements, so the proportions may vary depending on different products. Moreover, manufacturing standards and regulations in different countries and regions may also affect the setting of component proportions.

Generally, to ensure the processing performance of PVC Celuka board and make it have good drilling and nailing performance while not easily cracking, the content of calcium carbonate can be controlled between 30% and 40%. When the content of calcium carbonate is too high, the hardness and brittleness of PVC Celuka board will increase, and processing difficulty and cracking during drilling and nailing may occur. On the other hand, when the content of calcium carbonate is too low, the density and hardness of PVC Celuka board may decrease, affecting the stability of drilling and nailing. It should be noted that the content of calcium carbonate is not the only factor affecting the processing and mechanical properties of PVC Celuka board; other factors such as PVC content, filler particle size, and processing conditions also need to be considered. In practical applications, a comprehensive consideration and control of the above factors based on specific requirements and circumstances are necessary to obtain optimal performance and processing results.
