It is very important for the synthesis of polyurethane adhesives and sealants, which directly affects the mechanical properties and process In a broad sense, most of the weak reductants are antioxidants and are selected for different industrial USES. Weak reductants with high chemical and physical stability, or with low toxicity, can be skillfully used as antioxidants in formulations. For example, citric acid is a weakly reducing organic acid that can be used in beverage formulations to act as an antioxidant. Food is easy to oxidize and deteriorate for a long time, so a small amount of antioxidant can be added to prolong its storage time. High polymer materials such as plastic, synthetic fiber and rubber are prone to thermo-oxygen degradation. Adding antioxidant can maintain the excellent performance of high polymer materials and prolong their service life.

Which kinds of cakes can only be used as fertilizer and cannot be used as feed
Pancakes, in general, are known for their high protein content, rich oiliness, and the presence of a significant amount of blue phospholipids, making them a valuable source of animal feed. However, not all types of cakes are suitable for consumption or feeding. For example, tea cakes found in southern regions contain saponin, a naturally occurring toxin that is harmful to both humans and animals. Similarly, Tongzi cakes contain oleic acid and saponin, which make them unsuitable for use as feed. Additionally, castor bean cake is toxic and should never be used as a feed ingredient.
When purchasing such products, it's essential to be cautious and check the type of cake before using it. If you're considering using these cakes as organic fertilizers, they must first be crushed and soaked in water for several days. This process allows for proper decomposition and fermentation, turning them into effective basal fertilizers. It's recommended to apply them to the soil at least one to two weeks in advance, ensuring that the fermentation process is complete. This prevents any potential harm to seeds or young plants when planting. Always take care to follow proper preparation methods to maximize the benefits while minimizing risks.
