Carbon black and Rubber Carbon black (CB) and silica have been used as the main reinforcing fillers used to increase the performance of rubber. Since each filler has specific advantages, the use of silica/CB compounds improves the dynamic and mechanical properties of natural rubber vulcanization. However, the optimum ratio of silica to CB must be refined to provide optimum properties […]
History of carbon black
In the past, soot, which is similar to carbon black, was used to write papyrus letters in ancient Egypt and bamboo strips in ancient China. The production of carbon black was a type of cottage industry initiative when the method of paper production was discovered in the second century. After the canal process in 1892 and from the mid-1970s, most […]
What are the unique uses for carbon black ?
Vegetable carbon black is a type of natural edible color that is produced from plant materials such as coconut skin or from green bamboo, refined by the carbonization process at high temperature. Its production is through steam activation. Steam activation is achieved by charring vegetable fibers. To achieve this process, raw materials such as nut shells, peat, wood and cellulose […]
What is main rule in urea price in market ?
Urea price uptrend In China and India, urea production is coal-based. After China and India, other major urea producing countries have good natural gas reserves.

What the quality of the final fruit is, is directly dependent on the activities that are carried out from the time of planting seedlings to the time of harvesting its products. Fertilization is one […]
What is the difference between SSP and TSP?
Superphosphates are fertilizers that can provide phosphate minerals to plants. The main difference between simple superphosphate and triple superphosphate is that simple superphosphate is produced from phosphate rock and sulfuric acid, while triple superphosphate is produced from phosphate rock and phosphoric acid. We can denote single superphosphate as SSP, while triple superphosphate as TSP. In addition, phosphorus content is another […]
What are fertilizers ?
Chemical fertilizers (the so-called black manure and white manure) play a role in providing about 40 to 60% of the world’s food resources. Chemical fertilizers include one or more food sources needed by plants, which can exist in all three forms of solid, liquid or gas phases. These compounds can also be added to the soil,It can be sprayed directly […]
Effects fertilizers on human health
Leakage of chemical compounds in fertilizers into soil and water is a potential factor to introduce these compounds into the human food pyramid. Entering chemical compounds such as nitrogen derivatives into the human body can cause disease in humans. Some believe that one of the reasons for the high rate of cancer in the northern parts of the country is […]
