From June 28 to June 30 at the 6th China Bioindustry Conference in Taizhou, Jiangsu, Shanghai Hongli Purification Technology Co., Ltd. launched a high-efficiency chromatographic separation device that has attracted widespread attention. The promotion of this self-developed and domestically-produced device means that the situation in which high-performance chromatographic separation equipment is monopolized by a few foreign companies has finally been broken.

At present, more than 20 high-efficiency chromatography devices with completely independent intellectual property technology have been successfully run for more than two years in a number of biomedicine and fine chemical companies in Zhejiang and Guangdong, and the purification effect is better than existing domestic and foreign products on the market. It meets the requirements of the enterprises for high-purity chemicals. The technical indicators have reached or even exceeded the international advanced level and can completely replace imported equipment.

Professor Hong Xian’s technical director Professor Song Xianhong told reporters that many biochemical primary products contain impurities, and each impurity content is very low. It is very difficult to efficiently purify these primary products, and the grade of the product is extremely difficult to increase. Industrial chromatography is used. Technology is easy to achieve a high degree of purification. At the same time, many target products have low concentrations in raw materials, high impurity concentrations, and many types. To extract high-purity target products from these raw materials, industrial chromatography techniques can only be used. The technology has achieved good results after its application in the biochemical and fine chemical fields.

According to Song Zhili, Executive Director of Hongli Corporation, chromatography technology is a large class of industrial technologies with high-efficiency separation and purification capabilities. It can efficiently separate many difficult-to-separate mixtures from other separation technologies and produce high-purity products. It is mainly used in industrial production. Preparation of chromatography techniques. At present, Hongli has developed 10 specifications of chromatography columns to meet the needs of various types of chemical purification units. The equipment can be widely used for the isolation and purification of protein molecules such as vaccines, antibodies, and enzyme preparations, highly purified nucleic acids and peptides, supercoiled DNA viruses, polysaccharides, etc., and the height of serum proteins, albumins, blood antibodies, and various genetically engineered recombinant products. Purification and so on. At the same time, the device can also remove various impurities that the existing separation technology equipment cannot separate and can not see with the naked eye.

It is understood that this product not only has high separation accuracy, but also facilitates the loading and unloading of separation media. Each batch of operation and chromatography media can be cleaned and recycled quickly and simply in half an hour. The separation time is only similar to the market. 1/8. The service life of the components in the column is long, and the service life of the distributed components, in which the mobile phase is evenly distributed, is more than five times that of foreign products. The price of industrial large-diameter columns is less than 1/2 that of foreign products of the same type.

What`s Powder Coating

Powder coating is a dry finishing process that has become extremely popular. Powder coating is used on a wide array of products. More and more companies specify powder coatings for a high-quality, durable finish, allowing for maximized production, improved efficiencies, and simplified environmental compliance. Used as functional (protective) and decorative finishes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties.

Advantages over other coating processes

1. Environment friendly. Powder coatings contain no solvents and release little or no amount of volatile organic compounds (VOC) into the atmosphere.

2. More thicker coatings without running or sagging than conventional liquid coatings.

3. Perfect color consistency. Powder coated items generally have fewer appearance differences than liquid coated items between horizontally coated surfaces and vertically coated surfaces.

4. A wide range of speciality effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.

5. Curing time is significantly faster with powder coatings compared to liquid coatings especially when using ultraviolet cured powder coatings or advanced low bake thermosetting powders.

Powder Coating Process

The Powder coating process involves three basic steps: raw material preparation or the pre-treatment, the powder coating application and curing.

Powder Coating Substrate Considerations

Before applying the powder coating material, you must first consider the substrate material that you will be coating. It is very important to have a clear understanding of the true composition of the surface of the part.

ALUMINUM:

ALUMINUM CASTING

COLD/HOT ROLLED STEEL

CAST IRON

BRASS

COPPER

ZINC

STAINLESS STEEL

Powder Coating Properties:

Powder Coating Colours

RALAL Range, Pantone Range, and other Natural Colour Systems (NCS)

If you have a Powder Coating Colour requirement that we do not stock we are usually able to source powders from the above ranges within 48 hours.

Powder Coating Gloss Level

Gloss is measured as a percentage.

1. Matt Powders are between 20% and 30% gloss.

2. Semi-gloss Powders are usually around 60-65% gloss.

3. Gloss Powders at least 80% and can be 85%.

Powder Coating finishes

1. Textured Powder Coating:

2. Ripple/Leatherette Powder Coating.

3. Hammerite Finish Powder Coating.

4. High Temperature Powder Coating.

5. Anti-Bacterial Powder Coating.

6. Clear or Tinted Powder Coatings.

Application Field

1. In automotive applications:

a) some primers used on bodywork have converted to powder. This has given improved coating quality and provided ecological advantages.

b) where a functional as well as a decorative finish is desirable powder coatings are being used increasingly eg.

i. - wheels,

ii. - bumper bars,

iii. - mirror frames,

iv. - oil filters,

v. - battery trays,

vi. - coil springs and

vii. - heads.

2. Appliances

a) Specially formulated, hard and scratch resistant powder coatings are replacing the energy-intensive porcelain finishes on washer tops and lids.

b) Powder coatings are being used on range housings, freezer cabinets, drier drums, and microwave oven cavities.

c) Outdoor furniture, farm and garden implements and garden tractors also are being finished with powder coating materials. - Interior fluorescent light reflectors are coated using a highly reflective, very thin powder coating.

d) Exterior lamp housings on highway and parking deck fixtures are coated with specially formulated powder which give ultra violet light protection and added corrosion protection
