Recently, the joint press release issued by the Ministry of Finance and the Ministry of Housing and Urban-Rural Development has caused a sensation in the industry for subsidies for ground-source heat pump applications. This move has set the tone for ground-source heat pump promotion. The data shows that at present, the market share of ground source heat pumps is less than 7% in the domestic air-conditioning market. Local governments have granted incentives and subsidies for companies using ground-source pump and financial subsidies through financial subsidies, which has become the largest source of ground-source heat pump products in the market. driving force.

PYRITE__As fillers used in grinding wheels/ abrasive tools
Place of Origin: Henan Luoyang, China
Pyrite, Iron pyrites, pyrites lump, Ferro sulphur, Pyrites powder.
Product Description
Detailed introduction: is filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.
Formation of a protective layer
4 FeS2 + 11 O2→2 Fe2O3 + 8 SO2
400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
FeS2→FeS + S

Ground-source heat pumps have risen for many years and many of them have government policy support. In recent years, obvious government subsidies for various local governments have gradually joined. In theory, the development of ground-source heat pumps should have entered the booming season. Why is it still so? Under the policy binding?
Causes of such phenomena, industry experts believe there are the following main points:
First of all, the initial investment cost of ground source heat pump is too high, and the initial promotion is difficult. Take an ordinary few hundred square meters villa, the installation of a ground source heat pump system is no less than 100,000, the same price to install home central air conditioning, indoor multi-line And so on, you can install 3-5 sets.
Secondly, China's ground-source heat pump industry itself is still not perfect in its standards and technical application specifications. There are many problems in the development and utilization of low-temperature geothermal resources in China. The first is the lack of a comprehensive national standard for geothermal heat pump products and their technical specifications. The two cannot be effectively unified. In addition, most of the domestic geothermal heat pump promoters are equipment manufacturers. In the provision of ground source heat pump equipment sets, it is not possible to provide an overall system design, resulting in energy saving of the generator set and energy saving of the system.
Finally, China lacks a scientific evaluation system for ground-source heat pump systems and a strict market access system. In addition, the management system for government incentive funds is not perfect, and the more vicious circles that create more rewards are not.
(1)The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.
(2) 4 FeS + 7 O2→4 Fe2O3 + 4 SO2
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.
(3) It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)→FeS(l).
