Can be mixed with oil to improve engine life protection agent.
Automotive additives on the market are messy. Including lead, zinc, chlorine, molybdenum, phosphorus, graphite and other harmful substances in a large number of additives. The role of such products is to deal with oil, hoping to change the oil viscosity and composition to increase the wear resistance of oil. However, it is extremely harmful during actual use. It mainly causes the corrosion of machinery and easily leads to the blockage of the oil circuit and the oil, making the three-way catalytic converter ineffective and causing air pollution. Such additives have been banned in foreign countries for a long time. State Bureau of Technical Supervision, the State Environmental Protection Agency is also preparing to issue a document, forbidding the sale of such products in our country. Consumers in the choice of automotive additives when the best choice by the relevant state departments or certified by the authority testing of qualified products.
For propane, natural gas synergies, can improve propane volatilization, natural gas combustion temperature, the natural gas combustion temperature can be increased 400
-600 ℃, can completely replace the acetylene, propane in the industrial applications.
Concrete additives can significantly improve the physical and chemical properties of concrete to improve the strength of concrete, durability, saving the amount of cement, reduce the size of structures, so as to achieve energy conservation and improve environmental and social benefits of a class of material.
According to the main function is divided into four categories:
(1) additives to improve the rheological properties of concrete mixes, including various superplasticizers, air entraining agents and pumping agents;
(2) adjust the concrete setting time, hardening properties of additives, including retarders, early strength agents and quick-setting agent;
(3) additives to improve the durability of concrete, including air-entraining agents, waterproofing agents and rust inhibitors;
(4) additives to improve the performance of other concrete, including air entraining agent, expanders, antifreeze, colorants, waterproofing agent and pumping agent.
