Centrifuge classification and function

There are three international classification methods for centrifuges: according to the purpose, according to the speed and according to structure:

Classified by purpose: divided into preparative centrifuges and preparative analytical centrifuges.

Preparative Centrifuge: Centrifuge for separation, concentration, and purification of samples only.

Preparation and analysis centrifuge: not only can separate and concentrate, purify the sample, but also can observe, photograph, measure, digitally output, and print the automatically displayed centrifuge through the optical system.

According to the speed classification: divided into low-speed centrifuges, high-speed centrifuges, ultra-centrifuges.

Low-speed centrifuge: The rotation speed is within 10,000 rpm or relative centrifugal force within 15000×g.

High-speed centrifuge: The rotation speed is within 10,000 ∽ 30000 rpm or the relative centrifugal force is within 15000 ∽ 70,000 × g.

Ultracentrifuge: Rotating speed above 30000 rpm or relative centrifugal force above 70,000 x g.

Classified by structure:

In general, high-speed and low-speed centrifuges are classified according to their structure and function. There are many varieties and there is no uniform standard for each manufacturer. Can be divided into table-top centrifuges, multi-tube micro tabletop centrifuges, cell smear centrifuges, blood-washing tabletop centrifuges, high-speed refrigerated centrifuges, large-capacity low-speed refrigerated centrifuges, low-speed refrigerated centrifuges, bench-top high-speed refrigerated centrifuges, benchtops Low-speed automatic balance centrifuge. In addition, there are triple-type (five-joint) high-speed refrigerated centrifuges abroad, designed for continuous centrifugal use.

Centrifuges are machines that use centrifugal force to separate the components of a mixture of liquid and solid particles or liquid and liquid.

Centrifuges are mainly used to separate the solid particles from the liquid in the suspension; or to separate the two incompatible emulsions in the emulsion (for example, to separate cream from the milk); it can also be used to eliminate Liquids in wet solids, such as washing wet clothes with a washing machine; special overspeed tube separators can also separate gas mixtures of different densities; use different characteristics of solid particles of different densities or particle sizes in the liquid, some settlement Centrifuges can also classify solid particles by density or size.

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.
