Ten years ago, China’s thermal insulation materials were based on perlite and rock wool thermal insulation materials. At that time, China’s perlite plants had sprung up across the country. Later, because of the construction process, the material itself is low in strength, and the issue of high water absorption rate is difficult to solve, China's insulation market is withdrawn. Later, organic materials such as polyphenylene plates with lower thermal conductivity appeared, and later extruded plastic plates appeared, so that organic insulating materials such as polyurethane occupied the domestic insulation building material market for nearly 10 years. During the booming period of the polyurethane industry, China’s largest polyurethane production, consumption, and exporting country has become China’s largest. It has a pivotal position in the world. The polyurethane industry including polyurethane foam has promoted the development of the country’s economy and has also provided a lot of employment for the society. post.
It can be said that if the mountains do not turn around, the organic materials will have a defect of poor fire resistance and will be eliminated by the market. The WW inorganic heat insulation materials with fire-fighting nature will solve the problems of waterproofing and strength, and adding green environmental protection weights will naturally reappear in front of people, which is bound to become the development direction of heat preservation materials.
Moisture-proof and waterproof performance is the important development direction of insulation and heat-insulating materials. The water absorption rate is an important factor that should be considered when choosing insulation materials. The thermal conductivity of water at room temperature is 23.1 times that of air. Insulation material not only greatly reduces its thermal insulation after absorbing water, but also accelerates the corrosion of metal, which is very harmful. The void structure of the insulation material is divided into several types: connected, closed, and semi-closed. Except for a small number of organic foams, the majority of the voids are closed. The other insulation materials, regardless of the void structure, are water-absorptive, and they are connected with gaps. The capillary penetration of water absorption, so the overall water absorption is high.
Fireproofing of insulation materials, in the past two years, frequent building fires, wall external insulation materials have become the focus of attention, while insulation materials in the emphasis on energy-saving insulation at the same time, human life is bound to determine the direction of development of insulation materials. Strict implementation of the Fire Bureau of the Ministry of Public Security issued the '65 Document' has no doubt. Do not talk about the prevention of fire should be from the insulation system, material integrity and construction management, such as starting from the kind of painless words. To improve the fire-retardant properties of thermal insulation materials, the state will give policy attention, and domestic Class-A thermal insulation materials will surely develop rapidly.
Inorganic insulation materials (such as vitrified beads, etc.) should focus on reducing energy consumption during production, limiting dust and fiber emissions, and reducing binder usage.
Organic insulation materials (such as polystyrene foam insulation, polyurethane foam, etc.) should focus on finding more suitable foaming agents to replace F11; improving the flame retardancy of materials and reducing the production costs of materials.
The wheel of history is always on the forefront. In the current stage of inorganic insulation materials, as a company producing insulation materials, we must grasp the direction of the market and study products that are more in line with market demands in order to obtain the driving force for sustainable development. As a user, it is more to comply with social needs and trends and to make choices that are beneficial to others.

A laboratory centrifuge is a piece of equipment used to separate components of a mixture based on their density and size. It works by spinning samples at high speeds, which creates a centrifugal force that causes the heavier components to move to the bottom of the tube or container. The lighter components remain at the top or in the supernatant.
Laboratory centrifuges are used in various fields such as biology, chemistry, and medicine. They can be used for DNA extraction, protein purification, cell separation, and blood analysis. They are essential tools in research and diagnostic laboratories.
We have Mini Centrifuge,Low Speed Centrifuge etc.
