Summer or several cold days is the season of high frequency of air-conditioning use. This is a normal air-conditioning use, but because of the noise of the external machine is too large and triggered discussions across the country, with the neighbors fighting intelligence, please visit the relevant departments Testing, looking for environmental protection bureaus, and even resorting to the law, the forum in the collective effort, QQ group buzzing, but the problem is still not resolved. The noise problem is still plaguing us. In a few months, it will be the summer when the neighborhood relationship is tense. So, is your coping strategy well thought out? There are many reasons for the external noise of the air conditioner. One of them is the vibration generated when the external machine works. For the air conditioner external machine that can not meet the requirements of noise reduction and vibration reduction after the maintenance company requests maintenance, it may wish to try the external air conditioner shock absorber. The external air conditioner shock absorber is an elastic support element placed at the bottom of the air conditioner outboard. For a simple example, the phone is set to vibrate mode. The sound produced on the table is much louder than the sound generated in the air. The external air conditioner damper is to support the air conditioner, plus Hank. Sri Lanka's unique design, vibration reduction effect is very good, compact and lightweight, simple installation, the price is much smaller than the maintenance costs. Particularly suitable for use in home air conditioners. Hangzhou Hanks Sound Insulation Technology Engineering Co., Ltd. is a professional enterprise in noise control and has accumulated rich experience in noise control of civil buildings. Noise management is a sunrise industry and is not well known, but Hanks in Hangzhou started very early. Has more than 30 years of experience in the management of external air conditioning in the area of ​​vibration damping investment in research funding and human resources, currently has HBYQJZ damping spring shock absorber and HDTJZ damping spring shock absorber two air conditioner shock absorber , With good vibration isolation effect, low natural frequency, small damping coefficient, easy maintenance and so on. Hangzhou Hanks Sound Insulation Engineering Co., Ltd. provides wholesale and retail of shock absorbers for external air conditioners.

Silica (SiO2) in economical coating additives is a widely used inorganic filler. It plays a variety of roles in the coating industry and plays an important role in improving coating performance and reducing costs. The following are several main uses of silica in coating additives:
1. Enhance the mechanical properties of the coating: Silica particles can increase the hardness and wear resistance of the coating and improve the scratch resistance of the coating.
2. Improve leveling and hiding power: By adjusting the particle size and dispersion state of silica, the leveling of the coating can be effectively improved, while the hiding power of the coating can be improved and the amount of coating required can be reduced.
3. Adjust gloss: Silica of different particle sizes and forms can affect the gloss of the coating, thereby meeting the needs of different application scenarios.
4. Improve weather resistance and corrosion resistance: Silica as a filler in the coating can effectively block the damage of ultraviolet rays to the coating and enhance the weather resistance and corrosion resistance of the coating.
5. Reduce costs: Compared with some organic fillers or metal oxides, the cost of pure silica is relatively low. Using an appropriate amount of silica can reduce the production cost of coatings while ensuring performance.
6. Environmental protection: Silica is a natural non-toxic material that meets the requirements of modern coatings industry for environmental protection performance.
7. Auxiliary film-forming substance: In some specific coating systems, such as water-based coatings, silica can be used as an auxiliary film-forming substance to help form a stable coating structure.
In short, as an economical coating additive, silica plays an important role in improving coating performance, reducing costs, and protecting the environment. However, its specific application effect will be affected by factors such as coating formula and use conditions. Therefore, in actual applications, it is necessary to make appropriate selections and adjustments according to specific needs.
