What is the main use of Accelerator Dpg/Diphenyl Guanidine?
Accelerator Dpg is diphenylguanidine, which is an important auxiliary agent in the rubber industry. Its main uses are as follows:
First, as a vulcanization accelerator. In the vulcanization process of rubber, it can significantly accelerate the vulcanization speed and shorten the vulcanization time, which can improve production efficiency. In the manufacture of various rubber products, such as tires, hoses, tapes, etc., adding this substance can make the rubber change from linear polymer to network polymer structure faster, thereby enhancing the physical and mechanical properties of rubber, such as improving the hardness, tensile strength, and wear resistance of rubber.
Second, it can improve the flatness of vulcanization. It allows the rubber to maintain a relatively stable degree of vulcanization over a wide temperature range and a long time, prevents the rubber from deteriorating due to excessive vulcanization, and also avoids the poor physical properties of the rubber caused by insufficient vulcanization, ensuring the stability of the quality of rubber products.
Third, it has the effect of activating other accelerators. When used in combination with other accelerators, it can produce a synergy effect, improve the promotion effect, reduce the overall amount of accelerators, and optimize the vulcanization and processing properties of the rubber. For example, in some complex rubber formulations, when used in combination with thiazole and thiuram accelerators, the vulcanization speed and vulcanization characteristics can be flexibly adjusted to meet the production process and performance requirements of different rubber products.
Accelerator Dpg/Diphenyl Guanidine Chemical Properties
The chemical properties of the accelerator and Diphenyl Guanidine are unique. Diphenyl Guanidine is a white to light gray crystalline powder with a weak amine taste, slightly soluble in water, but easily soluble in organic solvents such as ethanol and acetone. Its melting point is quite high, about 148-151 ° C, which makes it stable under specific temperature environments.
From the perspective of chemical activity, diphenyl Guanidine is a weakly basic compound that can react with acids to generate corresponding salts. Because of its structure containing guanidine, it is often used as an organic base catalyst in the field of organic synthesis, which can effectively promote many chemical reaction processes.
In the rubber industry, diphenylguanidine is often used as a vulcanization accelerator, the so-called "accelerator". Its function is to significantly accelerate the vulcanization rate of rubber and improve the physical and mechanical properties of vulcanized rubber, such as enhancing its tensile strength and wear resistance. This is because it can interact with vulcanizing agents in rubber (such as sulfur) to promote more efficient vulcanization reactions.
In addition, diphenylguanidine can form complexes in the presence of certain metal ions, which makes it potentially useful in the separation, purification and analysis and detection of metal ions. Its diverse chemical properties make it play an indispensable role in many fields such as chemical industry and materials.
Accelerator Dpg/Diphenyl Guanidine What are the precautions during use
When using the accelerator and diphenyl guanidine, many precautions need to be carefully observed.
First safety protection. Both have certain chemical activity, and appropriate protective equipment must be worn during operation, such as gloves, goggles, protective clothing, etc., to prevent the agent from touching the skin and eyes and causing damage. And the operation should be carried out in a well-ventilated place. If conditions permit, it should be placed in a fume hood to avoid the accumulation of harmful gases and endanger human health.
The second is precise control of the dose. The dosage required for the two is quite different in different applications. Take the use of accelerators and diphenyl guanidine in the rubber vulcanization process as an example. Whether the dosage is accurate or not has a profound impact on the quality of rubber products. If the dosage is too small, the vulcanization reaction will not occur fully, and the physical properties of the product will be poor; if the dosage is too large, it may cause excessive vulcanization, and the rubber will become hard and brittle, which will also damage its performance. Therefore, it is necessary to accurately weigh the drug according to the established formula and experimental data before use.
Furthermore, storage must also be cautious. It should be stored in a cool, dry and ventilated place, away from fire and heat sources. Diphenylguanidine is exposed to heat or open flame, and there is a risk of combustion and explosion. And the two should be stored separately from oxidizing substances and acids to prevent chemical reactions, deterioration of the chemical agent or danger.
Repeat, and pay close attention to the reaction situation during use. Observe for any abnormal phenomena, such as sudden changes in temperature, color changes, and odors. If there is an abnormality, the operation should be stopped immediately, the cause should be found out, and corresponding measures should be taken to avoid the expansion of the accident.
At the end of the day, after use, properly dispose of the remaining chemicals and waste. Do not dump at will, and need to follow relevant environmental regulations and operating procedures to carry out harmless treatment to prevent environmental pollution.
When using accelerators and diphenylguanidine, safety, precision, caution and other factors should not be ignored, so as to ensure smooth operation and achieve the desired effect.

Accelerator Dpg/Diphenyl Guanidine compared to other congeneric products
Compared with other similar products, accelerator and Diphenyl Guanidine do have their own unique advantages.
First of all, its activity, Diphenyl Guanidine activity is quite good, which can effectively increase the reaction rate during the vulcanization process, and greatly reduce the vulcanization time. In the theory of ordinary vulcanization operations, other products may take a long time to achieve the expected degree of vulcanization, but Diphenyl Guanidine can significantly accelerate this process due to its high activity, which is very helpful for improving production efficiency.
In addition, it is versatile, and this product has a wide range of versatility. In the manufacture of many rubber products, such as tires, hoses, tapes, etc., it can play its role. In contrast, other congeneric products, or limited to the production of specific types of rubber products, are less versatile.
And diphenylguanidine has little effect on the physical properties of the rubber compound. The vulcanized rubber compound performs well in maintaining good tensile strength, elongation at break and other properties. Unlike some congeneric products, although vulcanization can be achieved, the physical properties of the rubber compound are damaged, resulting in a decline in product quality.
And because of its excellent dispersion in the rubber mixing process, it can be evenly distributed in the rubber compound to ensure uniform vulcanization reaction and avoid quality defects caused by uneven local vulcanization. In addition, diphenylguanidine is relatively simple to operate, does not require excessive production equipment and processes, and can be effective without adding too many complex facilities and cumbersome processes. It has obvious advantages in cost control and production operation convenience.
