I have been engaged in the recycling industry for many years and have met many friends in the industry. Lao Li is one of them. The main thing he recycles is the keyboard. There are countless keyboards recycled every year, and people nicknamed him "Key Fairy".
By recycling keyboards, Lao Li earned 200 thousand a year. Many colleagues also joined the keyboard recycling after seeing Lao Li make money. Through them, I learned some secrets of keyboard recycling.
First, let's learn about the keyboard. ...
The keyboard is an external input device of the computer, which controls the computer to perform a series of functions by pressing keys.
According to the different working principles, keyboards can be divided into four types: mechanical keyboards, plastic film keyboards, conductive rubber keyboards and non-contact capacitive keyboards.
Each keyboard has its own characteristics. At present, mechanical keyboards are the most popular among young people. It uses a metal-like contact switch, which works by opening or closing the contacts. It has a loud voice and a strong sense of rhythm when used, and is suitable for typing and playing games.
The keyboard itself belongs to consumable equipment and is easy to be damaged. Internet cafes, enterprises and individuals have many used keyboards. In addition, the keyboard is updated faster, so there are more used keyboards.
The shell of the keyboard is made of plastic and metal, and the core is electronic components. If discarded at will, it will not only cause environmental pollution, but also waste resources. This is definitely not right. At this time, professional recycling personnel are needed to stand up and make full use of resources through reasonable recycling methods. This is a meaningful good thing in the mouth of "Key Fairy" Lao Li.
Then the question is, what is the value of the keyboard after recycling?
Value 1: Refurbish and resell.
There are many kinds of keyboards. Ordinary work keyboards have no high value or renovation value, but there are many expensive keyboards on the market, such as Amiro, Leopold, Filco, etc., and the ordinary ones cost more than 1000 yuan.
After "Key Fairy" Lao Li recycled the keyboard, the first thing he did was to sort it out. Among thousands of second-hand keyboards, a precious keyboard was selected. These keyboards are of high renovation value, and many of them are glitches, which can be used by simple renovation. This is a refurbished keyboard on the market, or a second-hand keyboard.
Keyboards that are recycled for tens of dollars or even a few dollars can be sold for hundreds of thousands by simple renovation, which is also one of the values of second-hand keyboards.
Value two: recycling shell
There are many kinds of keyboards, usually plastic, and a few are metal and wood. This kind of keyboard is generally high-end customized and of high value. The metal shell can be recycled as scrap metal, and the wooden shell can also be refurbished. Many people like wooden keyboards, and the price is not low.
The most common keyboard shell is plastic. There are generally two kinds of materials, ABS and PC alloy. No matter which material is plastic, it has high recycling value.
"Key Fairy" Lao Li will let the workers decompose the keyboard first, then put the shell into the pulverizer and then put it into the pool for cleaning. In this way, two different kinds of plastic particles can be obtained, which can be recycled and processed into other plastic products.
Value three: power cord
There is a long power cord on the keyboard. Generally speaking, after the keyboard is damaged, the power cord will not be damaged unless it is badly worn, but it doesn't matter. Some manufacturers of lamps or small toys like to recycle waste wires.
Nothing they produce is of high value, and there is no high demand for raw materials. Small wires removed from various electrical appliances are their first priority.
Value four: silica gel
Under each keyboard key, there is a silicone pad or a whole silicone pad.
Silica gel is a highly active adsorption material, and its main component is silica. It is stable in performance, non-combustible, recyclable and widely used.
Inorganic silica gel can be used as a desiccant and can be used to make mobile phone cases, so that mobile phone cases have better fall resistance. Silicone gel can be used in many industries, such as construction, electronics, textile, automobile, machinery, leather and paper making, chemical industry, light industry and so on, and has high recycling value.
Value 5: Silver-plated paper recycling silver smelting.
Some people say that the most valuable thing in the keyboard is silver-plated paper. As the name implies, silver-plated paper contains silver.
"Key Fairy" Lao Li will carefully collect silver-plated paper after disassembling the keyboard. Someone specially recycles this thing and takes it back to refine silver. Lao Li said that the value of silver-plated paper is very high, and a ton of wool is worth at least 10 thousand yuan.
Value 6: Circuit board
There is also a core part in the keyboard, which is the circuit board.
Most people's keyboards are broken. I don't know where they are broken. I just know that they can't be used, so I threw them away. In fact, many times circuit boards are good, with high recycling value and can be refurbished and reused.
The transformation value of the circuit board on the ordinary working keyboard is not high, but the circuit board on your keyboard is very good. When renovating the keyboard, it is the best core and has high value.
The above six points are approximate values of keyboard recycling, which may have other uses. After all, in the recycling industry, the keyboard is also a detailed category, which is very deep. Even people in the recycling industry will not know the ropes if they have not recycled keyboards.
As the saying goes, interlacing is like a mountain. To outsiders, recycling waste materials means collecting junk. In fact, the recycling industry is very profitable, such as keyboards. How do ordinary people know that a small keyboard is so valuable?
Old computer keyboards can be recycled;
First, the shell outside the computer keyboard is made of recyclable pp material.
Second: the film under the computer keyboard keys is a tpe component and can also be recycled.
Third: Electronic components in computer keyboards are generally unnecessary and have no recycling value.
Generally speaking, old computer keyboards can be recycled.
