Technical requirements and application advantages of seed storage

April 03 05:12:42, 2023

As a big country in agricultural production, the quality of seeds will directly affect the production of agriculture and the interests of farmers. The storage technology of seeds is also increasingly important. In recent years, the construction of seed deposits has also become increasingly important. Because the seed's shelf life is the same as that of general agricultural products, its moisture content is inseparable from the temperature and humidity of the storage environment. Therefore, the seeds should be dried before entering the store, and the seeds should be kept at the corresponding temperature and humidity.

The safe storage period for general seeds is:

1. Long-term storage of seed cold storage: The temperature in the storage tank is below -18°C, and the relative humidity in the storage tank should be less than 50%. The storage period is 50 years.

2. Cold storage of seed in mid-term storage: The storage temperature of the reservoir is -4 to 0°C and the relative humidity is less than 50%. The storage period is 15 years.

3. Short-term storage of seed cold storage: The relative humidity of the library at 10°C is less than 75% and the storage period is 3 years.

Based on the above data, it can be seen that the lower the temperature and relative humidity in the seed storage, the longer the safe storage period of the seed. Therefore, the design of seed storage is not only to control the temperature of the reservoir, but also to control the relative humidity. Through a large number of seed storage practices in low-temperature seed storage, the accumulated grain seed storage technologies include: the most common storage technologies, low-temperature and moisture-proof storage, and the seeds that have been selected and dried to a level below the safe moisture content are packed into sealed moisture-proof metal cans. Or aluminum foil composite film bag, and then it is stored under low temperature and dry conditions. Canned, aluminum foil composite film bags can also be evacuated into a vacuum or semi-vacuum state when sealed to reduce the oxygen content in the container, so that the storage effect is better.

Matting Agent For Economic Coatings

Description



1, Silicon Matting Agent is a syntetic, micronized amorphous silica gel having porosity and high purity. The chemical structure of this product is based on Silicon Dioxide (SiO2). Matting agents are used to reduce the gloss in a variety of coatings applications. The application segments for silica gel matting agents include wood furniture coating, industrial coating, coil coatings, automotive coatings and decorative coatings as well as printing inks, leather coatings and textile coatings


2, Silicon Matting Agent usually used for general wood coatings, industrial coatings,plastic coatings. The general process is to attain silicate liquid by the acid neutralization reaction of sodium silicate solution, then processing it with filtering, washing, drying, finally let is go through our advanced crushing equipment for ultrafine grinding. It is a kind of virulent insipidity, nonflammable fluffy white powder, which is soluble in caustic soda and hydrofluoric acid only. Other characteristics are no decomposition, discoloration under high temperature, but with certain water imbibitions.


Feature


1, Easy to Disperse: Advanced rubbing technology makes narrower distribution of diameter of granules, so that matting agent can be easily added in any production procedure and can be easily dispersed, which saves the processing time.

2, Excellent Transparency: Products high purity lead the refractive index inosculate with resin index.

3, 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.


Application Area


1, General Industrial Paints, General Metal baking Paints, General Decorative Paints.

2, General NC wood Paints, PU wood Paints, furniture wood Paints, wood decorative Paints.

3, General Printing Inks, Gravure Printing Ink, Offset Printing Ink, Screen Printing Ink, Printing Packing Material.


Superiority


1, We are the realizable supplier for some international company and export to many countries. Such as AkzoNobel, Valspar, Nippon Paints, Dgl Camel, Taiho Paints and PPG.

2, We set up a research and development center to study new silica products to use special application.

3, We are the largest production of silica gel in China, and focus on Paint/Coating Market about 25 Years, with advanced technology and good experience to develop paint silica matting agent products.
