Help accelerate the development of environmental protection IoT

- National Environmental Protection IoT Technology Research and Application Engineering Technology Center is about to accept

The State Environmental Protection Internet of Things Technology Research and Application (Wuxi) Engineering Technology Center was approved for construction by the Ministry of Environmental Protection (Huanhan [2014] No. 130) in July 2014 with a construction period of two years and has now entered the stage of acceptance. The center to Wuxi Hi-Tech Internet Technology Development Co., Ltd. as the basis, the collaborating units are: Wuxi Internet of Things Industry Research Institute, China Environmental Science Research Institute, MEP Information Center, Nanjing Institute of Geography and Limnology, Chinese Academy of Sciences, Wuxi City Environmental Monitoring Central Station, Southeast University, Wuxi City, Everbright Analysis Technology Co., Ltd.

The center makes use of the technological agglomeration advantage of "China Center for Perception" in Wuxi to build five professional test platforms for IoT system simulation, R & D and test, including design simulation test platform, engineering dedicated test platform, device system environment test platform, flexible Pilot platform and field test platform, you can achieve the Internet of Things from the initial design sample library extraction, program simulation, production test process planning, hardware system testing, system reliability verification of the entire industry chain service support.

Center construction and implementation of the "Internet of Things + environmental protection" ideas for the construction of environmental protection technology innovation, around the environmental Internet of Things perception of network technology, lake water quality monitoring sensor technology, distributed computing technology, environmental protection big data mining technology and other environmental networking areas Urgent need to solve the common and key technical issues to carry out research, completed from the knowledge to product conversion. And, by combining "environmental perception, environmental protection," Wuxi environmental monitoring IOT demonstration project, to achieve the application of research results validation.

At the same time, the center is also actively involved in the development of the environmental protection IoT industry, focusing on the analysis of industry technology trends and industry dynamics, and preparation of technical development reports in the field of environmental protection IoT. At the same time, it should give full play to the good foundation in the formulation of national and industry standards, make use of the favorable conditions of the leading unit of the national IOT working group, and gradually consolidate and popularize the basic commonality of environmental IOT based on the national common standards and the standardization system of environmental information And application standards, research and formulate standards and norms that include the system architecture of environmental awareness, transmission, application support, management and operation, and lay a foundation for the industrialization of IoT and promotion of technologies.

The construction of the State Environmental Protection Internet of Things Engineering and Technology Center has led to the innovation and development of the mass integrated technology of the Internet of Things, the new environmental monitoring equipment and the application of mining technology for environmental protection big data, promoted the significant change of the environmental management mode, and provided a platform for the construction, operation and operation of the environmental Internet of Things Victoria explores the reproducible marketization and socialization patterns.

Injection Blow Moulding

Definition of Blow molding

Blow molding is a common process for production of hollow containers, ranging from commodity products such as soda or water bottles to highly engineered products such as gas tanks and electrical enclosures. The two most common types of blow molding are extrusion blow molding and injection blow molding with many variants related to handling of the parison and molds.

Blow molding processes:

Three main types of blow molding

l Extrusion Blow Molding

u Take melted plastic

u Extrude the parison with compressed air into the mold

u Features two variations: continuous and intermittent

l Blow Molding

u Produce small medica and single-serve bottles

u Large quantities of hollow glass and plastic objects

u Via pin to blow air into mold to inflate and cool the product

u Restriction on the bottle design, only allowing a champagne base to be made for carbonated bottles.

Injection stretch molding

Injection stretch molding is suitable for cylindrical, rectangular, or oval bottles and has two different main methods, notably the single-stage and two-stage processes

With the single-stage method,

the same machine is used to both preform manufacture and bottles blow the object. This method is highly suitable for low volumes and short runs

In the case of the two-stage process,

the plastic is first molded into a [preform" using the Injection Molding process. The [preforms" are then packaged and fed after cooling into a reheat stretch blow molding machine. While a high capital cost and a large floor footprint are necessary, injection stretch molding can produce very high volumes and feature minimal restrictions on bottle design. The bottles can also be a completed item for a third party to blow

Materials: PE, PVC, PC, PP, PS

Applications:

l To produce bottle-shaped, hollow thin-wall molding products and bulky products, such as seasoning, water bottles, cleaning agents, shampoo and other packaging supplies

l And produce trash cans, gasoline cans, and even the capacity of up to a ton of chemical barrels and fishing products transport boxes

Advantages

l Thin wall forming products, materials and cost saving

l Low cost of mold, rich mold materials

l Can produce large, complex shape hollow products

Disadvantages

l Low dimensional accuracy

l Thickness of the forming product wall is difficult to control and easy to have uneven problem

l Product surface is prone to flow marks, rough but not delicate
