On July 24th, a plastic dry grinder was running continuously in the production workshop of Huzhou. The production of PTFE fluoroplastic was being scraped. 'The grinder used to grind only 10 kg per day. Now I use the grinder I invented. More than 300 kilograms can be ground every day, exported to Italy, Turkey, Vietnam, Japan and other countries. ' Recently, in a fluoroplastic products processing plant in Deqing, Zhejiang, worker Cai Jianguo proudly told reporters.
This plastic dry grinder, together with a set of water grinders, enabled the efficient recycling and reuse of 'Plastic King' scraps, and also allowed Cai Jianguo to obtain 10 patent certificates.
PTFE fluoroplastic is extracted from fluorite. It has the characteristics of acid resistance, alkali resistance, cold resistance and high temperature resistance. It is widely used in electrical, aerospace, defense and military industries.

However, due to these characteristics of 'Plastic King', the processing of processed scraps has become a problem. More than 10 years ago, the 'Plastic King' trim was mainly landfilled, but it could not be degraded after being buried underground for 100 years. Can not be ignored.
In recent years, China Fluoroplastics Association has repeatedly stated that it is necessary to make full use of fluoroplastic waste to reduce pollution. Many manufacturers of fluoroplastics began to think about the 'prospects' of 'Plastic King' scrap.
Some manufacturers try to use the grinder to grind the scraps, collect the powder, and recycle it by the process. However, the continuous grinding of the grinder will produce high temperature, which will cause the grinding wheel to burst and cause danger. In addition, the grinder can only grind every day. More than 10 kilograms of scrap, efficiency, efficiency is not optimistic.
Similarly, the grinding and recycling of 'Plastic King' scraps also inspired Cai Jianguo's thinking.
'If I have a high-performance grinder, I can recycle the scraps at a low price and process them into higher value materials. 'Cai Jianguo keenly smelled the 'market space'.
Cai Jianguo, who graduated from Deqing Technical School (now Huzhou Technician College), has many years of production experience and a better understanding of fluoroplastics. The mechanical and electrical knowledge he learned during his studies also increased his confidence.
Dismantle the old machine, make parts, add gauges... Cai Jianguo tried to change, changed the test, the drawings one by one, gradually piled up.
'Sometimes, I sleep and dream of grinding machines. When I wake up, I quickly climb up and write down the inspiration of my dreams.' Talking about the trial production experience of the grinder, Cai Jianguo recalled, 'From 2003 to 2008 I am in the warehouse every day. I am a designer, a car mechanic, a fitter, a welder, etc.
'I will never forget the heavy snow in the last few days of 2008. I have never seen it since I was born. It was that day, the various parts of the grinder were completely successful in the whole machine combination test!' Cai Jianguo was very excited, and his voice was even higher than eight degrees.
'Being out of the workshop is the middle of the night, the street is full of snow, the road is empty. I think, today, I can sleep peacefully.'
The reporter learned that the plastic dry mill invented by Cai Jianguo can grind PTFE fluoroplastics more than 300 kilograms a day, which can achieve 24 hours of continuous operation; a group of machines of water grinding machine run at the same time, only one person to watch, the production capacity is dozens of times.
The news of Cai Jianguo's successful development of the grinder has spread, and the peers have come to observe it. Orders have come to the fore. Nowadays, hundreds of grinders have been sold, which solves the problem of nowhere to fill the scraps for many fluoroplastic processing plants. Eco-environmental contribution.
Cai Jianguo's grinding machine is not only favored by domestic factories, but also exported to Italy, Turkey, Vietnam, Japan and other countries under the introduction and promotion of a foreign trade company in Deqing.
Cai Jianguo is very valuable to take out a thick stack of pamphlets wrapped in kraft paper. These are the patent certificates that Cai Jianguo obtained for inventing the grinder, including 9 "utility model patent certificates" and 1 "invention patent". certificate".
'Nine new patented parts constitute an invention patent. 'Cai Jianguo's teacher Shen Shichun told reporters, 'As the saying goes, 'The layman looks at the excitement, the insider looks at the doorway.' These heavy patent certificates carry too much effort of Cai Jianguo. . '
At present, the plastic grinding machine developed by Cai Jianguo is still being improved, and the sixth generation product has been born.
