Breaking the international monopoly Ningbo enterprises have developed new environmentally friendly brass materials

IPHONE5 may be ahead of schedule and may be listed as early as August. Recently, the news circulating on the Internet is worth looking forward to for Apple fans. However, you may not know that either the IPHONE or the IPAD has used the new type of material developed and produced by the Ningbo company—environment-friendly lead-free and easy-cutting brass.

This kind of brass sounds like it may make you an outsider. Explain to you first that brass is an alloy of copper and zinc. This material is widely used in the manufacture of valves, water pipes, faucets, air-conditioner connecting pipes, radiators, and so on. It can be said that brass is in the lives of ordinary people. everywhere.

However, brass is very hard and it is difficult to cut and process into the ideal shapes of various products. Therefore, people will add “lead” when they are manufactured. In this way, lead brass will have good plasticity at high temperatures, making it easy Processed into a variety of ideal shapes.

However, this raises another problem. Lead is not environmentally friendly. When the blood lead concentration in the human body exceeds 30 μg/100 ml, symptoms such as dizziness, insomnia, and abdominal pain will occur. Therefore, countries such as the United States and the United States have strict regulations on the use of brass, which must be lead-free, and international high-end electrical appliances are also required to lead.

Brass not only has to be lead, but also has the characteristic of being cut. Such a material is “environment-friendly lead-free and easy-cutting brass”. This is a very high technical requirement. For a long time, only two companies in Germany and Japan have mastered the technology.

In 2002, a company engaged in R&D and production of high-performance, high-precision non-ferrous alloy materials in Yinzhou District focused its attention on environmentally friendly lead-free and easy-cutting brass.

“Since this year, Chief Engineer CAI Yuhua led the technical innovation team to overcome the technical difficulties. After years of research and development, he finally discovered a special material called 锑, which can replace lead. With the addition of 锑 brass, it is easy to cut and shape. , And no harm to the human body.” Ningbo Bowei Alloy Material Co., Ltd. Board Secretary Yuan Boyun said.

At present, the Ningbo company has applied for international patents, and world-renowned companies and even top 500 companies have thrown olive branches. "In addition to Kohler and TOTO, each IPAD and IPHONE have our own environmental protection brass." Zhao Hongbin, director of the R&D center, said, "Apple has appointed Foxconn to us for two years in a row. Last year, Foxconn purchased more than 1,400 from us. t Precision copper alloy rods."

It is understood that this Ningbo company plans to build a production base in the Binhai Investment and Venture Park. As of May this year, the purchase intention has reached 7500 tons, which is basically the world's top 500 companies such as Andrew, Siemens, Apple, Panasonic and so on.

At present, the lead-free brass project has been listed as a major achievement project in the national "Eleventh Five-Year" science and technology support program. The person in charge of the Ningbo Municipal Science and Technology Bureau said that this project has eased the situation in which China's high-end lead-free and easily-cutting brass rods are heavily dependent on imports.

CLR: Clearance

SM : Store the data

ON/OFF: Switch

Rm: Extra the data

M/ft: Conversion between metric and foot

Data display panel


Power supply

The stored data

The displayed data

Metric

Foot

1. ON/OFF : Switch.

2. m/ft: it means the conversion between metric and foot. If you select (m), the displayed data is based on metric. If you select (ft) ,the displayed data is based on foot.

3. SM: Store the data. You could save the data that shows on the display panel by pressing this button. It could store 5 records that respectively show on M1, M2,M3, M4, M5.( Refer to Table 1)

Before storing After storing Full of the memory

(Table 1)

4. RM: Extract the stored data from SM. For example, if you have already stored the measuring data 5M as M1, 10M as M2. But now the measuring data is 120.7M, you could press the bottom RM once then the digital display panel will shows the the data of M1. The top right of the display panel shows [R". The data of the digital display panel will return to the present data after two seconds. ( Refer to Table 2). If you press the RM twice, the data of the M2 will show on the display panel, the [R" also is on the top right. The data of the digital display panel will return to the present data again after two seconds.

Present data Press the RM Once After 2 seconds

(Table 2)

Present data Press the RM twice After 2 seconds

(Table 3)

5. CLR: Clearance. Once you press this button, the present data will be deleted.

4.Precautions for use

Please open the handle lock to adjust the suitable height of this instrument at first and then close it before using the instrument. Put away the kickstand and turn on the power. Put the wheel on the road to be measured when the data is 0.0m on the digital display panel. Please press the bottom CLR if you want to delete the present data.
