Feed
Refers to the industrially processed and produced feed for animal consumption, including single feed, additive premixed feed, concentrated feed, compound feed and concentrate supplements.
Food
Food additives refer to chemical synthetic or natural substances added to food for the purpose of improving food quality, color, aroma and taste, as well as for preservation and processing requirements. Food additives generally do not have to be food, and they do not necessarily have nutritional value, but they must meet the above-defined concepts, that is, they do not affect the nutritional value of food, and have the effect of preventing food spoilage, enhancing food sensory properties or improving food quality.
Engine oil
A protective agent that can be mixed with oil to improve engine life.
Automotive additives on the market are messy. Among them, there are many additives containing harmful substances such as lead, zinc, chlorine, molybdenum, phosphorus and graphite. The function of this type of product is to treat the oil, hoping to increase the anti-wear property of the oil by changing the viscosity and composition of the oil. However, in actual use, it is extremely harmful, mainly causing mechanical corrosion, which can easily lead to blockage of oil circuits and oil filters, make the three-way catalytic converter fail, and cause air pollution. Such additives have long been banned in foreign countries. The State Bureau of Technical Supervision and the State Environmental Protection Administration are also preparing to issue documents prohibiting the sale of such products in my country. When consumers choose automotive additives, it is best to choose products certified by relevant state departments or qualified by authoritative institutions.
Gas
Used for the synergy of propane and natural gas, it can increase the volatilization of propane and the combustion temperature of natural gas, and can increase the combustion temperature of natural gas by 400-600℃, it can completely replace the application of acetylene and propane in industrial industry.
Concrete
Concrete additives are a class of substances that can significantly improve the physical and chemical properties of concrete, improve the strength and durability of concrete, save cement consumption, and reduce the size of structures, thereby saving energy consumption and improving environmental and social benefits.
It is divided into four categories according to the main functions:
(1) Admixtures to improve the rheological properties of concrete mixtures, including various water-reducing agents, air-entraining agents and pumping agents;
(2) Admixtures for adjusting the setting time and hardening properties of concrete, including retarders, early-strength agents and accelerators;
(3) Admixtures to improve the durability of concrete, including air-entraining agents, waterproofing agents and rust inhibitors, etc.;
(4) Admixtures to improve other properties of concrete, including air-entraining agents, expansion agents, antifreeze agents, colorants, waterproofing agents and pumping agents, etc.
