China's new building materials industry has developed along with the deepening of reform and opening up. From 1979 to 1998, it was an important historical period for the development of new building materials in China. After 20 years of development, China's new building materials industry has basically completed the development process from scratch, from small to large, and has formed an emerging industry nationwide, becoming an important product category and a new economic growth point in the building materials industry. At present, the new building materials industry encounters difficulties and obstacles. The new energy-saving building materials mainly include new wall materials, chemical building materials, new thermal insulation materials, and architectural decoration materials. Although there is market demand, in fact, due to cost and market constraints and technical barriers, the development of new energy-saving building materials is currently difficult. In fact, people's choice of building materials directly affects the development of energy-saving building materials. At present, in the interior decoration, many owners are not willing to spend money to use new energy-saving and environmentally-friendly building materials products because of lack of energy-saving and environmental protection awareness. As a result, the formaldehyde content in the living room after the renovation exceeds the standard, which not only endangers the health of the owner, causes economic losses, but also causes A huge waste of materials. Although the new energy-saving building materials have the advantages of high technology content, low resource consumption, long service life and less environmental pollution, the cost of use is not higher than that of ordinary building materials. However, in terms of market price, it does not have a competitive advantage. The production cost of energy-saving building materials is too high, making the price of these new products difficult to fall, and it is difficult to become the darling of the market. For example, the new insulation material polyurethane rigid foam, currently only accounted for less than 10% of the external wall insulation. Only a few large-scale real estate development companies that focus on brand building use polyurethane rigid foam exterior wall insulation systems. At this stage, the competition of most new building materials enterprises in China is concentrated on the middle and low-end products, and the products with higher technical content are less, and the competition in the high-end field is not fierce. The most obvious is the plastic pipe and door and window industry. At present, the middle and low-end products of the country have experienced overcapacity and market growth slowdown. Domestic plastic water pipes and fittings are mostly general-purpose products. The use of pipes and fittings with high requirements and high added value is less, which greatly limits the application of the market, and the application of plastic pipes in the high-end field is only in its infancy. The main reason is that the industry lacks scientific and technological input in energy conservation and resources, and lacks technological innovation, which has affected the overall level of the industry. The PC transparent board market, which is favored by the market, is unable to achieve breakthroughs in technology due to high technical requirements. Most of the market positions are occupied by foreign companies. At present, in the production and sales of plastic building materials such as wall insulation materials and roof waterproof materials with high profit margins, the production enterprises have short-sighted behaviors of quick success and instant benefit, which has hidden hidden dangers for the development of the industry. In addition, building energy-saving materials such as cement hollow bricks instead of clay solid bricks and clay hollow bricks have been widely promoted, but such products also have problems of insufficient strength and large construction differences that affect the quality of the project. In addition to the two major bottlenecks mentioned above, the related incentive support policies are not perfect, the building materials industry itself has low thresholds, low concentration, disordered market competition, and the pressure on enterprises to move to high-tech and high-end markets. It is an important reason why new energy-saving building materials are difficult to get rapid development in a short period of time, and grasp the important development pulse and market opportunities.
High Flow Peristaltic Pump
The working principle of a High Flow Peristaltic Pump like a snake swallowing an egg. The hose is constantly squeezed through the roller to make the hose generate pressure and push the liquid forward. Our designers make the Peristaltic pump head and hose fit perfectly by designing precise roller size and pump head structure. So as to achieve the purpose of accurate liquid metering transmission or filling
1. Clean and pollution-free: the fluid only passes through and touches the peristaltic pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. With stop valve function, no siphon, no seals, stop valve and check valve function.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
