High-speed development of concrete shotguns
The concrete shotcreting vehicle integrates three technologies, concrete pump, air compressor system, and accelerator system, and integrates the functions of walking, concrete pumping, and injection. It is mainly used in railways, highway tunnels, slopes, water conservancy and hydropower Tunnels and culverts and various underground military engineering, civil construction and other underground engineering areas.
At present, most of the structures used in China's market for shotcreting equipment are simple, relatively simple in function, low in operating efficiency, and poor in environmental adaptability. They do not have the capability of self-propelled rapid response, making it difficult to meet special construction and construction requirements. Strict time requirements. The concrete shotcreting vehicle is a product that is particularly difficult to achieve in the concrete machinery technology, technology content is particularly high. It is mainly used in the construction of railway and highway tunnels, water conservancy and hydropower, subways, mine tunnels, military facilities, various underground building construction and emergency rescue. The basic process is to use liquid pressure to transport the pre-mixed concrete to the spray gun through a pipe. Compressed air and quick-setting agent are applied to the spray gun. The concrete is sprayed onto the sprayed surface at high speed, and the concrete is formed after rapid solidification and hardening. Floor. With the large-scale development of modern engineering construction, the market demand for shotcreting vehicles has rapidly expanded in recent years. This requires that concrete shotcreting vehicles must meet the needs of the market and the general public both in terms of technology and work ability.
Modern concrete shotcrete vehicles have the following advantages: 1. High quality of concrete, using sophisticated metering equipment and technology, accurate measurement of raw materials such as sand, stones, cement, and fly ash to ensure the quality of concrete is stable. With a high-power mixer, the concrete is fully stirred and has good workability and strength. 2. The construction process is good. The pump truck can continuously pump concrete to ensure that the concrete is formed integrally and the quality of the project is strong. The concrete cloth is completed by the pipework of the pump truck arm, which has high accuracy and low waste. 3. The project is of high quality. The construction of housing, water conservancy, highway construction and other projects adopts modern mechanical construction. The technological process is advanced, which can greatly improve the quality, safety and service life of the project. 4. The driving is light and the design width, total weight and height of the pump truck meet the requirements of rural roads and can be easily driven on narrow and rugged rural roads. 5. The construction is flexible. The short boom pump truck adopts a flexible four-section boom design. The limited site space can also be flexibly constructed, effectively solving the problems of housing, roads, and water conservancy construction in urbanization. 6 The installation is fast. The mixing station is compact and compact. It can be transshipped through 5 9.6m trucks after splitting. The mixing station is a modular installation and the installation speed on site is fast.
Melt-blown Non Woven Fabric
Made from special polypropylene resins using innovative techniques, melt-blown filter media is a highly efficient solution for high-performance filters. Increased density means greater capacity for containing dust and a longer lifespan for the product.
PP super-fine fiber filter material is a new type of filter
material made of polypropylene special resin with the melt-blown non-woven
technology.The fiber of the product,with three-dimensional net
structure,decreases the filtering resistance and can contain more dust.The
product is ideal to be used in initial,medium and high efficiency
filter,self-air-cleaner,vacuum cleaner etc.due to its low resistance and high
efficiency.The product can also be used for liquid filtration,oil stain
disposal,water purification and other purposes.
Product Performance:
The product is from hydrocarbons with innocuity,insipidity,white
and light character.
The fiber distributes uniformly,softly and
compactly,having the trait of high intensity,low resistance and high efficiency.
Acid and alkali resistant,with high melting point(167-174°C)and stable
performance.
