More than 30,000 years ago, humans began to tie the beaten stone to a wooden stick to make a stone hammer, which is the first version of hammer with a handle. The hammer handle is more convenient for power, and the lever composed of the hand and the hammer handle can magnify the impact force, so that the hammer's impact power and speed are greatly improved. But primitive people with "rubber band" (generally refers to the tough plant fiber or animal skin, etc.) tied hammerhead easy loose head, accidentally because of loose will lead to hammerhead fly out cause "accidental injury"!

In the Bronze Age, the hammers received another crucial upgrade. In addition to the bronze metal material to more power, also appeared a hole hammer head, China called "Qiong", inserted the stick which is very easy to fixed. This design can be seen in many tools and weapons and has been used to this day.

The real modern claw hammer was invented by American blacksmith David medell in 1840. He USES a wedge Qiong eye - insert after the hammer handle reverse lay a wedge, it more firmly hammer head. He also upgraded the horn to a curved surface, making it easier to pull nails. The new claw hammer was very popular when it was launched.

Roller manufacturing precision, using the inner plating method diamond grinding wheel manufacturing process, can stably produce high-precision, complex surface roller, the service life reaches 20,000 to 50,000 times, the storage time of the grinding wheel should not exceed the effective period of the grinding wheel, the grinding wheel of resin and rubber bond From the date of leaving the factory, if the storage time exceeds one year, it must be passed after passing the test.

Diamond tools for processing hard and brittle materials mainly include various diamond saws and diamond products. Although the application range and processing characteristics of various tools are different, the wear mechanism is basically the same. The storage place of the diamond grinding wheel should be kept dry and the temperature is suitable to avoid. Mix with other chemicals. Prevents the wheel from getting wet, low temperature, overheating and being attacked by harmful chemicals to reduce the strength.

In order to prevent the corrosion of the wooden handle of the hammer which may come from the Chipping Hammer Manufacturers, it is necessary to pay attention to vacuum and high pressure impregnation during the processing, and this step is very important. The preservative should be driven into the interior of the wooden handle of the hammer. At the same time, the chemical reaction process of the active ingredients of some preservatives with starch, cellulose and sugar in wood was completed. Secondly, it needs to be characterized by high temperature, because the wooden handle needs to allow the preservative to penetrate into the interior of the wood as uniformly as possible in a high temperature environment, so that it can exert its maximum use advantage.

Note on the use of China Caulking Gun:

1. Filling should be smooth and firm

The construction primer must be smooth, strong and dust-free. When filling joints, it is especially important to use poor quality white cement and caulking agent for narrow seams.

2. The seam width should be consistent

In order to ensure the overall effect of the tile paving, the tile caulking needs to be uniform and narrow, and it is better to use a plastic cross to position, otherwise the effect is beautiful. However, if the small bricks with multiple cross-connections are constructed, the principle of first applying vertical seams and then applying horizontal seams should be applied. When cross-cutting points are encountered, the post-filling caulking agent should be scraped here to skip the light scraping and make caulking. The agent flows into the intersecting slits less.
