Our city has successfully developed the first domestic sewage suction and purification vehicle, which is expected to be popularized and applied in sanitation units, large enterprises and farms in the future. "For a long time, cleaning septic tanks has mainly relied on manual labor or sewage suction trucks. But both methods have certain defects." Saishun Environmental Protection The person in charge said that due to the harsh environment of this work, if relying on manual labor , not only labor-intensive, low efficiency, but also prone to the problem of incomplete cleaning. However, using a fecal suction truck for cleaning, it can only be transported to a designated location after extracting the dirt. The round-trip transportation is not only time-consuming, but also affects the operation efficiency. "For example, to clean the septic tank of a large-scale complex, in general, it takes 8 people to clean up for 3 days, but if a sewage suction and purification vehicle is used, it can be completed in 8 hours by 3 people." The person in charge introduce. Because all processing is done on-site in a relatively closed circulation system, there will be no leakage of dirt and peculiar smell during operation and transportation, so it will not cause secondary pollution to the environment.

  It is understood that this sewage suction and purification vehicle developed by an enterprise in our city has realized more than 90% of mechanized operations, not only cleaned thoroughly, but also "carried" a compressing and drying septic tank sewage treatment machine, which is completely processed on site. , Sewage is discharged by municipal pipelines, and the dung is treated as domestic waste, or made into organic fertilizer, which is not transported back and forth, and the purification of color steel plate greatly improves the efficiency. Is the cost of using mechanized equipment very high? "Actually, the cost of using this sewage suction and purification vehicle is lower." According to the person in charge, the cost of manually cleaning the septic tank is about 1.5 yuan per square meter, but the cost of using suction and purification The cost of sewage purification vehicles is only 1 yuan per square meter, which is reduced by 1/3. Moreover, since the cleaning of mechanized equipment is more thorough, for a building, it is enough to clean the septic tank once a year, and if it is cleaned manually, it will be twice a year. In this way, more cost can be saved.

  It is understood that similar sewage purification vehicles are only produced in the United States. Through independent research and development, enterprises in our city have mastered relevant key technologies. At present, the product has not only obtained 1 invention patent and 1 utility model patent authorization, but also included in the municipal key new product and high-tech product plan.

The characteristics of the color steel prefab house's light weight, spliced ​​installation and optional cutting determine the ease of installation of the prefab house, which can greatly improve the efficiency and save the construction period. The surface material and thermal insulation material of the fireproof color steel plate sandwich panel are non-combustible materials, which can fully meet the fire protection requirements of the prefab house. Various studies on durability have shown that it has been widely used in foreign countries for more than 40 years. The shelf life of color steel plates treated with special coatings is 10-15 years. After that, anti-corrosion coatings are sprayed every 10 years. The clear lines of the color steel plate are as many as dozens of colors, which can meet the needs of any style of mobile room color steel plate to achieve satisfactory results.
  Color steel plate coating is a product made of cold-rolled steel plate and galvanized steel plate, after chemical treatment on the surface, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. Some people also call this product "pre-rolled color steel plate" and "plastic color steel plate". Color plate products are produced in coils by manufacturers on a continuous production line, so they are also called color-coated steel coils. Color steel plate not only has the properties of high mechanical strength and easy forming of color steel plate material, but also has good decoration and corrosion resistance of coating material. Color steel plate is an emerging material respected in the world today. With the advancement of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards, color steel prefab houses are increasingly showing strong vitality and broad market prospects. Favored by interior decoration, office appliances and other industries.
  The color steel plate movable room has the advantages of light weight, high strength, thermal insulation, beautiful and durable, etc. It is a high-grade color steel plate that integrates color steel plate and decoration. The color steel prefab house is clean in construction and is widely used in large-span workshops, warehouses, office buildings, villas, roof additions, air purification rooms, cold storage, shops, kiosks and temporary housing. Light color steel sandwich panels with a weight of less than 14KG per square meter can fully reduce the structural load and reduce the structural cost of the prefab.

  The commonly used thermal insulation materials for color steel composite panels are: rock wool, glass fiber wool, polystyrene (EPS), polyurethane, etc., with low thermal conductivity, so the prefab house has a good thermal insulation effect. High-strength color steel plate uses high-strength steel plate as the base material (tensile strength 5600kg/cm) plus the most advanced design and roll forming. Therefore, the color steel prefab house has excellent structural characteristics.

The characteristics and advantages and disadvantages of my country's color steel plate, movable insulation series products are modular walls made of glass, melamine board, fireproof board, color steel plate, gypsum board and other decorative material panels. The inner part is made of aluminum alloy frame and steel, which has multiple functions such as fire prevention, moisture resistance, sound insulation, environmental protection and non-deformation. The interior style of the isolated space and the ultra-stylish hotel. The plastic surface has strong anti-corrosion performance, and the service life can reach more than 10 to 15 years. It can be cut, the construction is simple, and the construction period is only 1/5~1/10 of the general civil color steel plate. It is especially suitable for field assembly, addition of room height, large-span color steel plate structure and energy-saving wall renovation of old color steel plate. Strong seismic strain capacity. Color steel rock wool insulation slate rock wool board is better than the traditional sandwich color steel rock wool insulation board with a thickness of 100mm. For partition wall data and freezer wall data. It has excellent fire resistance, heat preservation and sound absorption properties. It is mainly used for thermal insulation and sound insulation of color steel plate walls and roofs; fire prevention and noise reduction of color steel plate partition walls, firewalls, fire doors and color steel ladder wells. Rock wool insulation pipe is a tubular insulation material made of basalt and other natural ores as the main raw materials, melted into fibers at high temperature, added with appropriate amount of binder, and cured. What should be paid attention to in the design of color steel house? Fire prevention measures for color steel structures With the acceleration of my country's modernization process, urban construction has entered a new stage of development, but in this process, construction personnel lack the recognition of fire hazards and corresponding prevention measures. There have been frequent fires in the construction sites of construction sites, resulting in significant wealth loss and casualties. In order to avoid the occurrence of similar incidents, in order to firmly curb the frequent fires of temporary houses on the construction site, and to create a good fire safety environment for the rapid development of the economy, the following precautions should be taken to strengthen the control of the construction site of the color steel plate structure: 2. It is not based on the power of the color steel plate equipment to select the corresponding color steel plate line format and arbitrarily supplement the color steel plate equipment, resulting in the overload of the color steel plate line and the heat and fire; the third is that the usual survival management is difficult to measure, and the construction site has not been equipped with corresponding equipment. Fire Equipment. Because most of the construction teams only focus on economic benefits and speed, but neglect safety, the ordinary construction sites are not equipped with the required fire fighting equipment. Some are equipped with fire-fighting equipment, most of which are furnishings, and most of the fire-fighting equipment is invalid, expired, and basically unusable. Many construction sites have not realized the temporary water source, and once a fire occurs, water cannot be taken immediately to put it out. Secondly, the national building materials industry standard does not require the combustion performance of the thermal insulation material in the color steel plate to achieve B1 level. Quality technical supervision institutions at all levels rely on JC 68921998 "Metal Surface Polystyrene Sandwich Panel" (hereinafter referred to as "Polystyrene Sandwich Panel"), JCPT86822000 "Metal Surface Rigid Polyurethane Sandwich Panel" (hereinafter referred to as "Rigid Polyurethane Sandwich Panel" National building materials industry standards such as "core board"), JCPT 86922000 "metal-faced rock wool and slag wool sandwich panels" (hereinafter referred to as "rock wool, slag wool sandwich panels") are responsible for supervising the production of color steel plates. However, "Polystyrene Sandwich Panel" stipulates that the "oxygen index is not less than 30%" for the thermal insulation material in the sandwich panel. The "B2 level" statutory "rock wool and slag wool sandwich panel" does not stipulate the combustion performance of the thermal insulation material in the sandwich panel. Only the fire resistance limit of the sandwich panel is made "when the thickness of the sandwich panel is greater than or equal to 80mm, the fire resistance limit is greater than or equal to 60 minutes. When the thickness of the sandwich panel is less than 80 mm, the fire resistance limit is greater than or equal to 30 minutes." The standard has not made a request for the B1 level of the combustion performance of the thermal insulation material in the color steel plate. Thirdly, there is a shortage of fire protection testing for the thermal insulation material of the color steel steel structure construction room. The test report issued by the manufacturer is a perennial issue, and the quality and technical supervision department Responsible for the supervision of the production and circulation of color steel plates, but its standards are insufficient for the requirements of combustion performance, or there are requirements in this regard, which are lower than the requirements of fire protection laws. The competent authorities of creation and public security fire departments are only responsible for temporary construction. The general supervision and management of housing applications, whether the combustion performance of thermal insulation materials in the currently sold color steel plate structure is B1, lacks the basis for requesting the construction unit to carry out compressive fire detection on the color steel plate structure. Therefore, the color steel plate structure construction room is formed. Insulation material combustion function succeeded, the request of B1 level is in the situation of supervision vacuum
