Weichai Heavy Machinery recently announced that according to the relevant provisions of the high-tech enterprise certification, the company will be recognized as a high-tech enterprise through procedures such as company declaration, local preliminary examination, and expert review. The publicity will begin on November 30, 2010. The publicity period is 15 working days.
As of the announcement date, Weichai Heavy Machinery has not yet received the written confirmation from the relevant department. The company will continue to pay attention to the follow-up progress of the matter and will promptly disclose the relevant confirmation documents.
Weichai Heavy Machinery currently implements a 25% income tax rate. According to the relevant regulations, within 3 years after an enterprise has obtained the qualification of a high-tech enterprise, the income tax shall be levied at a rate of 15%, and relevant preferential policies shall be enjoyed as prescribed. Weichai Heavy Machinery Chongqing Branch currently enjoys preferential tax policies for Western Development and applies a 15% income tax rate. After the company is recognized as a high-tech enterprise, Chongqing Branch will still implement a 15% income tax rate and enjoy relevant regulations as required. Preferential policies.
Humidifiers are mainly divided into two types: household humidifiers and industrial humidifiers.
Ultrasonic humidifier uses ultrasonic high-frequency oscillation frequency of 1.7MHZ to atomize water into ultra-fine particles of 1-5 microns, which can freshen the air, improve health, and create a comfortable environment.
According to experts, the advantages of ultrasonic humidifiers are: high humidification intensity, uniform humidification, and high humidification efficiency; energy saving and power saving, and power consumption is only 1/10 to 1/15 of that of electric humidifiers; long service life and automatic humidity balance , Anhydrous automatic protection; both functions of medical atomization, cold compress bath surface, cleaning jewelry and so on.
Direct evaporative humidifiers are also commonly referred to as pure humidifiers. The pure humidification technology is a new technology just adopted in the humidification field. The pure humidifier removes the calcium and magnesium ions in the water through the molecular sieve evaporation technology, and completely solves the "white powder" problem.
Thermal evaporative humidifiers are also called electric humidifiers. Its working principle is to heat water to 100 degrees in the heating body to generate water vapor, which is sent out by a fan. Therefore, the electric heating humidifier is the simplest humidification method. The disadvantage is that it consumes a lot of energy, cannot be dry-fired, has a low safety factor, and is easy to scale on the heater. The market outlook is not optimistic. Electric humidifiers are generally used in conjunction with central air conditioners and are generally not used alone.
Compared with the above three, the electric heating humidifier has no "white powder" phenomenon in use, low noise, but large power consumption, and it is easy to scale on the humidifier; the pure humidifier has no "white powder" phenomenon and no scaling, and the power is low , with an air circulation system that filters the air and kills bacteria.
Ultrasonic humidifier has high and uniform humidification intensity, low power consumption and long service life. Therefore, ultrasonic humidifiers and pure humidifiers are still the recommended products of choice.
