What is the ingredient ratio of the "Bis - (3 - Triethoxysilane Propyl) - Disulfide And Carbon Black Mixture" product?
"Bis- (3-triethoxysilanpropyl) -disulfide and carbon black mixture" The composition ratio of this product is really the key to its performance and use. However, because there is no exact literature to rely on, it can only be speculated according to common sense and common similar formulas.
Generally speaking, bis- (3-triethoxysilanpropyl) -disulfide is used in the mixture, or acts as a coupling agent, to enhance the bonding force between carbon black and other matrix materials, so as to improve the mechanical properties and stability of the overall material. If the ratio is too low, it may be difficult to fully exert the coupling effect, resulting in poor bonding of carbon black with the matrix and damage to material properties; if the ratio is too high, it may increase the cost, and excessive cross-linking may also reduce the flexibility of the material. Therefore, the ratio may be about 10% - 30%.
Carbon black in this mixture is often a reinforcing filler, which can significantly improve the strength, wear resistance, conductivity, etc. If the ratio of carbon black is too low, the material reinforcement effect is not obvious; if the ratio is too high, the material processing difficulty will increase and the fluidity will become poor. Therefore, the ratio of carbon black or between 40% - 70% is more common.
The remaining part or other additives, such as dispersants, antioxidants, etc., although the proportion is relatively small, generally 10% - 30%, its role should not be underestimated. Dispersants can help bis- (3-triethoxysilanpropyl) -disulfide and carbon black disperse evenly, while antioxidants can delay material aging and prolong service life.
It should be noted that the above ingredient proportions are only speculated based on common material formulations and characteristics. The actual proportion should be determined according to the specific application and performance requirements of the product, and can only be determined after rigorous experiments and tests.
What are the precautions for using the "Bis - (3 - Triethoxysilane Propyl) - Disulfide And Carbon Black Mixture" product?
"Bis- (3-triethoxysilanopropyl) -disulfide and carbon black mixture" During the use of this product, many matters need to be paid attention to.
The first is about safety. The ingredients contained in this mixture may be dangerous. Bis- (3-triethoxysilanopropyl) -disulfide, its chemical properties are active, or cause irritation to the skin, eyes and respiratory tract. Therefore, when using it, it must be fully armed, wearing protective clothing, goggles and masks, and beware of direct contact and inhalation, so as not to damage the body.
The second time is to store. It needs to be placed in a cool, dry and well ventilated place, away from fire and heat sources. Because its ingredients are exposed to heat or open flames, there is a risk of combustion or even explosion. And avoid mixing with oxidants, acids and other substances to prevent chemical reactions from occurring, causing deterioration or causing danger.
Furthermore, it is the norm for use. Before use, be sure to stir well to ensure that bis- (3-triethoxysilanopropyl) -disulfide and carbon black are evenly dispersed, so as to ensure stable product performance. During operation, strictly control the dosage and add it according to the established formula and process requirements. Excessive or too little may affect the quality of the final product.
In addition, after use, properly dispose of the remaining mixture and related utensils. Residues should not be discarded at will, and should be disposed of in accordance with regulations to avoid polluting the environment. Utensils need to be cleaned in time to prevent residual substances from corroding the utensils or affecting the next use.
Only when using "bis- (3-triethoxysilane propyl) -disulfide and carbon black mixture", pay close attention to the above matters, and operate strictly in accordance with regulations to ensure safe use and ensure product quality meets expectations.
What are the storage conditions for the "Bis - (3 - Triethoxysilane Propyl) - Disulfide And Carbon Black Mixture" product?
"Bis- (3-triethoxysilanpropyl) -disulfide and carbon black mixture" This product has critical storage conditions. It needs to be placed in a cool and dry place to avoid direct sunlight. Due to ultraviolet rays in sunlight, it is easy to cause photochemical reactions of the ingredients in the mixture and cause it to deteriorate.
In the warehouse, good ventilation must be done. Good ventilation can disperse harmful gases that may accumulate, maintain a suitable air environment, and prevent the quality of the product from being affected due to gas concentration problems. And the temperature also needs to be strictly controlled, and it should be in a lower temperature range. High temperature can easily enhance the molecular activity inside the mixture, trigger chemical reactions, and shorten the shelf life of the product.
Furthermore, this mixture should be stored separately from oxidants, acids and other substances. Due to its chemical properties, contact with oxidants may occur violent oxidation reactions; coexistence with acids may cause reactions such as acidification, which will damage the quality of the product. When storing, the packaging should also be well sealed to prevent moisture, air, etc. from entering and affecting the performance of the product. Following such storage conditions can maximize the quality and stability of the product.
How is the "Bis - (3 - Triethoxysilane Propyl) - Disulfide And Carbon Black Mixture" product compatible with other materials?
The compatibility of this product with other materials is critical to its effectiveness in various applications.
To know the compatibility of this mixture with other substances, it is necessary to consider the ancient saying that the physical properties, structure and reaction characteristics should be carefully observed. In this mixture, bis- (3-triethoxysilanopropyl) -disulfide contains siloxane groups, which are hydrolytic and can react with materials containing active groups such as hydroxyl groups to form chemical bonds and improve compatibility. If it is used with inorganic fillers containing hydroxyl groups, such as silica, it can be connected to it by hydrolysis and condensation of silane, and the compatibility is good.
Carbon black is an amorphous carbon with a variety of active groups on its surface. Its compatibility with polymer materials depends on polymer polarity and interaction. Polar polymers have strong interactions with carbon black surface active groups and have good compatibility; non-polar polymers have poor interactions and often need to be modified on the surface of carbon black to improve.
For this mixture and other materials, if other materials have groups that can react with silane or can form good interactions with carbon black, such as some polar polymers and inorganic materials partially containing active groups, the compatibility is expected to be good. However, with non-polar and non-active group materials, such as partial polyolefins, the compatibility is poor without treatment. It is necessary to adapt to different material characteristics, modify the mixture, or treat other substances to optimize compatibility and achieve the best application performance.
