With the continuous deterioration of the natural environment, dust has brought great harm to human survival and production, especially the products under the production of modern industry. Therefore, in order to strengthen the quality and reliability of their products, manufacturers have invested in sand and dust tests on the products. Then the appearance of the current sand and dust test box provides manufacturers with a time-saving, labor-saving, faster, and convenient platform for achieving the test purpose.

First, let's analyze the adverse effects of the dust used in the sand and dust test on the production process, product quality, economic efficiency, environment and ecological balance.

(1) Hazard to production. The dust in the air of the workplace is attached to high-end, precision instruments and meters, which can reduce the accuracy of these devices; it is attached to the transmission and running parts of machinery and equipment, which makes the wear and tear and the service life shortened; the dust can make certain chemical products , Mechanical products, electronic products, such as paint, film, miniature bearings, motors, integrated circuits, capacitors, televisions, video recorders, cameras, etc. quality decline; so that people in the production process affect the line of sight, reducing work efficiency.

(2) Hazard to the environment. Dust floating in the air can cause other harmful substances to attach to it, causing serious air pollution. Biological inhalation can cause various diseases, and cultural relics, monuments, and building surfaces can be corroded and polluted. In addition, a large amount of dust suspended in the air can reduce the visibility of the atmosphere, promote the formation of smoke, and affect the heat radiation of the sun.

(3) Impact on economic benefits. Mainly manifested in lower product quality, lower product qualification rate, and lower product price; due to shortened service life of machinery and equipment, increased investment in fixed assets, increased product cost, and weakened market competitiveness; occupational patients lost their ability to work due to dust , Medical expenses, nursing expenses, health welfare welfare expenses increase; working in high-concentration dust work places, operators worry about health, psychological burden is heavy, and lose their ability to work earlier than normal, so that enterprises can train technicians cycle Speeding up, large investment in training costs, and at the same time cause instability in labor productivity.

Secondly, dust and other substances have a certain energy. Due to the small particle size and large surface area of ​​the dust, the surface energy also increases. The surface area of ​​a piece of 1 g coal is only 5-6 c㎡, while the surface area of ​​1 g of coal dust is 2 m2. Dust and air can be mixed to form combustible mixed gas. In case of open flame or high temperature objects, it is easy to catch fire. The combustion process is completed in an instant, releasing a lot of heat energy, so that the combustion gas suddenly rises, the volume expands violently, forming a high expansion pressure. The oxidation reaction of the burned dust is very rapid, and the heat generated by it can be quickly transferred to the adjacent dust, thus causing a series of chain reactions.

It can be seen from this that the harm and energy of dust is so great that we cannot eliminate it, so we can only start from our own prevention. In terms of survival and living environment, we take various ways to isolate dust to minimize its impact on the human body, survival and life; in industrial production, we use the sand and dust test chamber to simulate the dust environment for product dust and dust resistance tests to enhance Product quality and availability improve economic efficiency.

Beijing Yashilin specializes in the production of sand and dust test boxes, with high quality and low price, and satisfactory service!

Blue Chalkboard

Blue, such as water and sky, give a comfortable feeling, symbolizing the void, infinity and divinity.
