The wind is often a "bad" friend, destroying production and destroying houses, but in many cases it is a "good" friend, blowing seeds to spread and spread, so the weather is not good or bad. The key is whether we humans can control it. , apply it reasonably. In ancient times, Zhuge Liang used the Dongfeng fire to burn the wall, which was because he had effectively mastered the knowledge of wind direction and wind speed, thus achieving a major military victory. Nowadays, in agricultural production, we can also turn wind disaster into wind energy and better serve agricultural production with the help of hand-held wind speed and direction .
The weather forecast often says "Northeast wind, 3--4 level", "Northeast wind" represents the direction of the wind, and 3--4 level represents the speed of the wind, also called wind. The hand-held wind speed and direction instrument is a small-scale agrometeorological instrument applied in the agricultural field, mainly for monitoring small meteorological services in agriculture. It consists of a host and a sensor. When the wind blows the cup, the information sensed by the sensor is transmitted to the host and displayed on the display. The instrument can help modern farmers to control the changes of the wind more accurately and in real time, so as to rationally arrange agricultural labor.
With the effective meteorological information provided by the hand-held wind speed and direction instrument, we can effectively prevent crops from falling due to windy weather and enhance the ability to cope with natural disasters. At the same time, it is better to be guided by meteorological information. The use of meteorology for agricultural services is more targeted and instructive, providing scientific guarantees for increasing agricultural production and income, and enhancing the confidence of farmers in farming.
At present, with the gradual development of meteorological services for agriculture, hand-held wind speed and direction instruments and other convenient agricultural meteorological instruments are widely used in various places. The instruments not only have high measurement accuracy, accurate data, but also are easy to carry and easy to operate. It satisfies the needs of meteorological monitoring in grassroots areas and provides important meteorological technical support for farmers in the jurisdiction.
Rutile Titanium Dioxide is used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.
At the same time, titanium dioxide has a good UV shielding effect, and is often incorporated into textile fibers as a sunscreen. Ultra-fine titanium dioxide powder is also added to sunscreen cream to make sunscreen cosmetics.
Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has the functions of strengthening, anti-aging and filling. Titanium dioxide is added to white and colored rubber products. It is resistant to sunlight under sunlight, does not crack, does not change color, has high elongation and is acid and alkali resistant. Titanium dioxide for rubber is mainly used in car tires, rubber shoes, rubber flooring, gloves, sports equipment, etc., generally anatase type. However, when used in the production of automobile tires, a certain amount of rutile products are often added to enhance the anti-ozone and anti-ultraviolet capabilities.

Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of fragrant powder use titanium dioxide instead of lead white and zinc white. You only need to add 5%-8% of titanium dioxide to the fragrance powder to get a permanent white color, making the fragrance smoother, having adhesion, absorption and hiding power. In gouache and cold cream, titanium dioxide can weaken the greasy and transparent feeling. Titanium dioxide can also be used in various other spices, sunscreens, soap flakes, white soap and toothpaste.
The glaze made of titanium dioxide has strong transparency, low quality, strong impact resistance, good mechanical properties, bright colors, and is not easy to be polluted. Titanium dioxide for food and medicine is titanium dioxide with high purity, low heavy metal content and strong hiding power.
