In the middle of August , there are still many hot weather in the south, and agricultural production should strengthen defense. Since entering in August, the northern Jianghuai, Jiangnan, South China, eastern Sichuan Basin and other places 4-9 light of day maximum temperature ≥ 35 ℃ weather, in which the southern most extreme maximum temperature of 39-41 ℃. According to the forecast of the Central Meteorological Observatory, in mid- August , Jianghan, Jianghuai, Jiangnan, South China, North China, Sichuan Basin and other places will still have high temperature, the average temperature is 1-2 °C higher than normal , and will be 5-8 days high. The temperature is 35-38 °C, and the daily maximum temperature in parts of Sichuan Basin, Chongqing and Jiangnan can reach 39-40 °C. The continuous high temperature affects the rice heading and flowering in the Yangtze River Basin, which leads to an increase in the empty shell rate and a decrease in the seed setting rate. The high temperature weather is also unfavorable for the greening and root development of the late rice in South China. Therefore, all localities should actively take countermeasures, rational irrigation, and water temperature adjustment to reduce the impact of high temperature weather. In the first season, the rice area is properly filled with deep water, and the daily irrigation and night drainage method is adopted to cool and humidify and reduce the influence of high temperature; the late rice field should maintain the shallow water layer, prevent high temperature burning seedlings, and at the same time, according to the growth of the seedlings, it is suitable for strong fertilizer. In addition, the recent continuous hot and cold weather is very unfavorable for the growth and maturation of other on-land crops, vegetables, fruits, etc., which may lead to leaf curling, falling flowers and fruit drop, etc., and reduce the yield and quality of vegetables, fruits and fruits. All localities should pay attention to measures such as covering, shading, early morning or evening watering to avoid high temperature heat damage.
Abrasive flap discs, commonly
known as flat emery cloth wheels, flap discs, flower impellers or elastic
discs, are a large variety of coated abrasive conversion products. It is a
method of pressing the cut coated abrasive discs one by one. It is formed by sticking
adhesive to the back cover plate along the circumference.
The Flap Disc is mainly
installed on hand-held Power Tools for grinding and polishing the welds, burrs,
chamfers, surface derusting, surface polishing, etc. of various metal and
non-metal parts. Compared with the resin grinding wheel for fixed abrasives, it
has Grinding and polishing can be completed at one time, shortening the
operation time, saving the cost of grinding, and improving the grinding
efficiency. The abrasive self-sharpness is strong and the utilization rate is
high. The air cooling does not damage the surface. The surface quality is easy
to control and cost-effective, reducing operator fatigue and increasing machine
life. And so on, so it is widely used in various industries or fields of
manufacturing.
The related abrasive products we can supply is Flap Disc Adhesive , Flap Wheels , Bonded Abrasives , and Abrasive Sanding Disc, such as Abrasive Fiber Disc, Sanding Screen Disc, abrasive silicon sandpaper, if you have any needs about abrasive tools, please kindly feel free to contact us.
Abrasive flap disc can be
divided into flap disc, Mini Flap Disc and Flexible Flap Disc according to
their shape. There are subtle differences in usage. The flap disc are
relatively hard and not easy to bend; the blades of flexible flap disc can be
bent at will. Shape, suitable for grinding the edges and corners of the
workpiece; mini flap disc is suitable for grinding smaller workpieces. The
following is a detailed introduction of the flap disc.
According to the
different abrasives, it can be divided into Zirconia Flap Disc,S/C Flap Disc, Ceramic
Flap Disc.
1.Zirconia Flap Disc
Mainly used for high alloy, stainless steel
and heat-treated steel; high-tensile, non ferrous metals.
2.S/C Flap Disc
Mainly used
for marble, stone, glass, and non-ferrous metals.
3.Ceramic Flap Disc
Mainly used for
grinding stainless steel, titanium, inconel, and other hard metals.
At present, flap discs are widely used in automobiles, stainless steel products, metal products, glass manufacturing and other industries, and have special effects on welds, solder joints, flash, rust removal and surface polishing. The reason why the flap disc is so widely used is because it has five advantages that cannot be ignored:
1. The flap disc blades have high hardness, high strength and strong grinding ability during use.
2. The flap disc has low noise, low vibration and long service life during use.
3. The flap disc has strong wear resistance and long service life.
4. It is not easy to generate heat and burn parts during use.
5. The use of flap disc can improve work efficiency.
The flap disc blades can be used instead of resin Grinding Wheels and steel wire wheels. They have a good effect on rust removal, grinding and polishing. It is a good way to polish and remove rust. It is worth choosing!
