Box type filter presses and frame filter presses are all "darling", but they also have their own characteristics. Plate and frame filter presses have a layered plate type filter plate, so the overall weight is lighter and easier to replace and move. In addition, its filtration speed is faster than that of the chamber filter press, and the filter cake storage space is also relatively large, and the plate-frame filter press filter cloth can better form a uniform pressure difference, so that the filter cloth and the filter fluid can be maximized. The limited contact ensures a better filter area. And there is enough space on both sides of the filter cloth to form an effective pressure difference, thereby improving the efficiency of the frame filter press. Compared with the frame filter press, the superior technology is the biggest advantage of the chamber filter press, with less loss when feeding, high temperature and high pressure, good sealing performance, uniform cake washing, low moisture content, and each The pressure in the filter chamber is not easy to be bad, which is basically applicable to all solid-liquid separation industries. However, there are also disadvantages such as low efficiency, poor filtering effect, and easy filter plate deterioration. From the overall perspective of the filter press industry, the contradiction in the filter press equipment market in China has become increasingly prominent in recent years. First of all, due to the relatively late start of China's filter press industry, no effective industry management mechanism has been established so far, leading to mixed industry as a whole, and the overall level of industry development can not be improved. Second, although there are many domestic filter press manufacturers, most of the companies with independent research and development capabilities have no new product development capabilities and production technologies. Experts said that the future development of filter press equipment is more difficult, and the road to development and survival must adapt to the following trends. First of all, the filter press equipment must adapt to the changing trend of market development, seize the direction of the market, and better think for the customer. Secondly, we must improve the overall performance of the equipment. In addition to ensuring stable operation of the equipment and improving the filtering effect, we must further improve the automation, humanization, convenience, and green of the equipment. It includes energy-saving equipment, low energy consumption, environmental protection and pollution-free, to ensure that the equipment will not cause secondary hazards during operation, and at the same time to achieve filter drying, reduce filter cake moisture, vigorously innovate in drying, breaking the traditional pressure filter Machine development bottleneck. The author believes that under the current background of increasing green environmental protection, China's filter press companies should make full use of the advanced achievements of modern science and technology, focusing on new products that are urgently needed for the development of national economy and national defense, and improve the quality and technological level of existing products. The development of filter press equipment that is urgently needed by industries such as food, pharmaceuticals, and urban sewage treatment will form a new growth point.
ZHENGDA Curing Agent is an efficient concrete curing agent, which is widely used in construction, road, bridge and other engineering fields. It is made of high-quality raw materials and has the characteristics of efficient curing, strong durability and convenient construction.
The main component of the curing agent is polyamide ester resin, which can quickly react with the cement in the concrete to form a high-strength chemical bond, making the concrete more robust and durable. In the construction process, only need to apply the curing agent to the concrete surface, and then mechanical polishing or grinding, you can achieve the ideal effect.
ZHENGDA curing agent can not only improve the strength and durability of concrete, but also effectively prevent the phenomenon of sand formation and powder drop on the surface of concrete. At the same time, it can also play a waterproof, dustproof, oil and other functions, making the concrete surface easy to clean and maintain.
The curing agent is suitable for all types of concrete surfaces, including newly poured concrete, old concrete restoration, industrial floors, etc. Not only that, it can also be used indoors and outdoors, adapting to a variety of environmental and climatic conditions.
In short, ZHENGDA curing agent is an efficient and reliable concrete curing agent, which has been widely used in construction, roads, Bridges and other engineering fields, and has become the preferred product for concrete surface treatment.

Sewage is a promising industry for Qingquan filter equipment industry
At present, the filter presses on the market are divided into a variety of uses and models, and the functions of the filter presses of different models are different, and the roles they play in the work are also different. Among them, the most widely used are the box type filter press and the frame filter press. It is understood that food, chemical, pharmaceutical, oil refining, sewage treatment and other industries need to use van and frame filter press equipment to separate solids and liquids.
