Application
Ultra-low frequency insulation withstand voltage test is an alternative test method for the power frequency withstand voltage test.The test procedure is greatly reduced, which is more advantageous than the power frequency test. It can be widely used in the AC withstand voltage test of cables, large high voltage rotary motors and power capacitors.This product combines the advanced technology of modern digital frequency conversion, adopts microcomputer control, step-up, step-down, measurement, protection fully automatic, and can perform manual intervention in the automatic promotion process. Because of the full electronic, the volume small weight light, large screen liquid crystal display, clear and intuitive, and can display the output waveform, print output test report. In addition, the following features need to be specified:

Product Features:
1.real and accuracy test results of current, voltage, waveform directly get from high voltage lateral sampling.
2.over-voltage protection: device stop running when output over setting max voltage, time <20ms.
3.over-current protection:double protection for high and low voltage, stop running accuracy protect high voltage according to set parameter, stop running when low voltage current over rated current, time <20ms.
4.no need to connect extra protection reactor because of high voltage protection reactor inside booster.
5.due to use high and low voltage closed loop control circuit, output without capacitive rise effect.

Matting Agent For Coil Coatings

Description

1, Coated Aluminum Coil refers to the aluminum coil through coating and coloring treatment generally includes PE coated aluminum coil and PVDF coated aluminum coil. Coated aluminum coil is widely used to manufacture aluminum composite panel, aluminum ceiling, roofing aluminum veneer, aluminum honeycomb panel, electronic products, etc. Coated Aluminum Coil is the most popular new material currently. It is especially suitable for interior decoration and AD boards. It can be classified matt and glossy according to coating gloss.

2, Matting Agent specialized used for the matte Coil Coating. It provided high matting efficiency, excellent coating appearance and better transparency. As well as low oil absorption, easy dispersion and smoothly touch with minimal impact of viscosity.

Characters

1, Highest matting efficiency: High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.

2, Surface smoothness and improvement in scratch resistance: These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.

3, Good Transparency: Products high purity lead the refractive index inosculate with resin index.

4, Good Dispersion: This series of products that can easily decentralized in any paint system, the average high-speed pulsator with 10-20 M/S of the line speed, after 10 minutes can be ok.

5, Excellent Hand-feeling: These silicas have minimal effect on the mechanical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.

Application Fields

Coil Coating, Coating for aluminum Coil.

Strengths

1, We located in a modern city, as a research, development and production for chemical raw materials, as well as one of the largest production bases of silica in China.

2, We will continue to invest in research and development, application technology and production capacities in emerging markets.

3, We are the leading raw material and technical solution provider to the Paint/Coating/Ink chemical Industry. We focus on Paint/Coating Market about 25 Years, with advanced technology and good experience to develop different kinds of silica matting agent used for different application.
