The difference between carbide method and ethylene method

The two methods of PVC production are calcium carbide method and ethylene method. What is the difference between them?


1. Different cost determining factors

The cost of PVC produced by calcium carbide method depends on the electricity price, and the higher the electricity cost, the higher the production cost.

The cost of PVC produced by ethylene method is directly linked to international crude oil prices, and fluctuations in oil prices will directly affect its price.


2. Significant differences in quality

PVC produced by the calcium carbide method has a moisture content 4-5 times higher than that produced by the ethylene method, and there are also 3 times more impurities,

This means that PVC produced by ethylene method has higher purity and more stable product quality.

Especially for high-end products, ethylene method is a better choice


3. Molecular weight distribution affects performance

The molecular weight distribution of PVC produced by calcium carbide method is wider

Resulting in higher thermal stability, mechanical properties, and weather resistance compared to ethylene method.

Vinyl PVC is more resistant to high temperature and aging, suitable for outdoor construction or harsh environment.

Calcium Carbide is also called calcium acetylide, which is a chemical compound having the chemical formula of CaC2. Mainly, it is used industrially for the production of calcium cyanimide and acetylene and Ethylene.

Calcium carbide is essential in the acetylene production process. This chemical compound plays a crucial role in creating acetylene gas, which is widely used in various industries. The production of acetylene from calcium carbide can sometimes pose challenges.

Calcium carbide is commonly used in agriculture to accelerate the ripening of fruits. The calcium carbide agricultural ripening process addresses several pain points for farmers and distributors, including the need for timely harvests and improved fruit quality.

In recent years, calcium carbide has gained prominence as a critical compound in various industries, particularly those involving chemical manufacturing and agriculture. As a leading calcium carbide supplier, NEW OCEAN GROUP recognizes the significance of calcium carbide's emergence in solving challenges in these sectors.

Handling calcium carbide safely is crucial for anyone who works with this chemical. Calcium carbide can produce harmful gases when exposed to moisture. Many people may not realize how dangerous it can be. It is essential to understand both the risks and the safety measures. In this article, we will uncover the facts about calcium carbide handling,

Finding quality calcium carbide can be challenging, especially for overseas buyers and distributors. Many companies struggle with searching for reliable suppliers, ensuring product quality, and understanding import regulations. Calcium carbide is used in various applications, including steelmaking, producing acetylene gas, and manufacturing PVC.

Calcium carbide plays a significant role in various industries, particularly in chemical manufacturing and agricultural practices. As a key chemical compound, its emergence has transformed processes by enhancing efficiency and productivity.

Carbide is used in different industries and applications including: (1) Production of acetylene The reaction of calcium carbide with water, producing acetylene and calcium hydroxide.
