Relevant data show that China’s solid industrial waste emissions and existing quantities rank first in the world, with annual tailings powder emissions of more than 600 million tons, and other industrial waste emissions such as fly ash, boron mud, etc. Very huge. The long-term shelving of industrial solid waste such as tailings powder not only causes serious waste of resources, but also causes pollution to the environment. After many years of research and development, the light composite materials project team of Liaoning University of Science and Technology adopts new technology to make tailings powder and other industrial wastes into light-weight thermal insulation composite wall materials. The old industrial pollutants that are difficult to handle turn into green building materials.
At present, Liaoning University of Science and Technology Engineering Training Center Building, National Bureau of Financial Security and System Equipment Engineering Technology Research Center of Liaoke University, and Analytical Testing Center Building of Tengji Development Area of ​​Anshan City have adopted this lightweight composite material as exterior wall building materials. Get good results. Among them, the “in-situ cast-in-place lightweight thermal insulation composite wall technology using wastes such as tailings powder†jointly developed by Professor Liao Keda, National People’s Congress deputy Liu Changqing and Professor Liao Kejun Hu Junyi has been selected as the key energy-saving reduction in Liaoning Province. The row technology catalogue, "In-situ cast lightweight thermal insulation composite wall products" passed the National Building Materials Testing Center, the National Building Decoration Materials Quality and Safety Supervision and Inspection Center, the National Fixed Fire Extinguishing System and the Quality Inspection Center of Refractory Components, Liaoning Provincial Building Materials Supervision Inspections of professional institutes such as inspection and inspection institutes were included in the catalogue of environmental protection equipment (products) encouraged by the State in the current development (2013 edition), and new product promotion certificates were obtained from the Department of Housing and Urban-Rural Development of Liaoning Province.
Lightweight composite material wall is made by light steel keel and cement board, and cast into industrial waste such as tailings powder, fly ash, boron mud, cement and compound additives. One-time forming of a composite wall, with green environmental protection, fire prevention, thermal insulation, heat insulation, sound insulation, light weight, high compressive strength, strong impact resistance, etc., as a non-load-bearing wall for industrial and civil buildings, it and traditional building materials Compared to the cost savings of more than 10%. In addition, they used a variety of formulations, using a large number of iron tailings powder, aluminum tailings powder, fly ash, boron mud and other industrial waste as the main raw materials, made a "lightweight rigid insulation building materials" series of products, and Adopting the “Intelligent Controlled Multi-Formulation Continuous Infusion Equipment†series of products to innovate the construction technology of traditional building walls, the construction efficiency has increased by more than 30%, and labor costs have been greatly saved.
“The backwardness of building materials production process, the lack of awareness of environmental protection in enterprises, the backwardness of relevant laws and regulations, and the lack of uniform industry standards for green building materials are the main reasons for restricting the manufacture of green building materials in China.†Professor Liao Keda and National People’s Congress representative Liu Changqing believe that the green of our country is currently green. Most building materials manufacturers use natural resources as raw materials, rarely use industrial waste such as tailings powder, combine the comprehensive development and utilization of solid industrial waste with the development of green buildings, and adopt advanced technology and intelligent construction equipment to achieve energy conservation in China. Reducing consumption, improving the ecological environment, etc. have important practical significance. He suggested that the government should vigorously promote green and energy-saving products in new rural construction, housing projects, and rural urbanization projects, increase policies and financial support for waste utilization, energy-saving emission reduction technology research and development projects, and promote it in various ways. Corporate basic research and technological innovation. (Reporter Hao Xiaoming correspondent Liu Guoliang)
Our automatic door kits include 1 motor+gear reducer, 1 belt,7 meter, 1 idle pulley, Microprocessor, 4 sets of carriage blue wheels, 2 sets of floor guides,2pcs remote control, 2 sets belt clamp mounting brackets, 1 power supply harness and cable connectors, 2 locator, Aluminum track whose length is 2.08 meter, 3 meter, or 4 meter.
We are a manufacturer of automatic door openers that are designed to provide people convenience. Automatic Door Systems` drive to provide that level of service is but one of the reasons why automatic doors are becoming more and more popular. Our Automatic Sliding Door systems are modern, space-saving and elegant.
Automatic sliding doors have many basic functions some of which include: automatic mode with full opening width and/or reduced opening width, and exit only for traffic control. The opening of automatic doors can also be adjustable to make the opening width smaller or larger. Important safety functions such as safety sensors prevent the door from shutting if persons or objects are in the detection zone. If the door leaves are inhibited when closing, they are immediately re-opened or if the door leaves are hindered when opening, they are immediately stopped by a safety automatic reversing mechanism.
Our most popular sliding automatic door. Think of this as the go-to door for everyday automation needs. All components fully tested and pre-assembled at factory for fast, trouble-free installation.
Applications: Retail, healthcare, airports, hospitality, clean rooms. Shenzhen Hongfa Automatic Door Co.,Ltd rated door is designed, test and certified to meet your environment needs. automatic slide doors for industrial, commercial, healthcare, and retail use. You will find our automatic sliding doors throughout in a wide variety of locations, including: Hospitals, Airports, Retail centers, Pharmacies, Hotels, Grocery stores, Hardware stores, Sporting goods stores, and more.
Automatic Sliding Doors can either be a single door sliding in one direction or bi-parting doors where each door leaf slides in the opposite direction. They are often used in grocery stores, entrances to shopping malls, hospitals and other applications where you want to provide your customers a hands free, safe and easy access to your building.In addition, one of the biggest benefits of automatic doors is energy savings. Since these doors only open when someone comes in or out of your building, it prevents the loss of energy when a door may otherwise be left open for a long time.
The control device of sliding automatic door contains basic function and extensional function, automatic operation / hold-open/closed/half-open to meet customer needs. Electric sliding door controller has multiple interfaces for complete access control systems for keeping your life and property more safety. Such as: safety beam photocell, electric locks, sensor etc. Its drive devices adopts European technology to integrate motor with gear box, which offers strong driving and reliable operation and increased power output , it can adapt to a large door.
Providing strength, beauty, and technology all in one package, Hongfa's line of automatic sliding doors provides entrance solutions for practically any application. An exclusive feature is Hongfa's sound-dampening track reducing operational noise to a mere whisper and stops vibration resonance that can be transferred to the building structures.
