Market and development trend of cooling tower packing

Fillers for plastics alone exceed 10000t per year, of which calcium carbonate accounts for about 2/3. The filler market is very large, but a large part of the filler is used in some products with immature technology. The main applications of fillers include: plastic construction paper paints and coatings cosmetics and pharmaceutical fibers food friction materials printing There are 4 types of polymers (PVC,PP,PA, polyester) that use the most fillers. The consumption of filler in each polymer can reflect the consumption of this polymer. Plastics are replacing many traditional materials, in order to make plastics have the required properties, but also requires the development of new filler technology. According to the current development situation, we can predict the future trend of the filler market. The following technologies will become more and more important: nano-filler, conductive filler, surface modification technology, filler mixture, dust-free filler form, special filler compatible filler, low-cost reinforced filler At present, we are committed to perfecting the filler technology and have developed many fillers with very high quality. However, high quality fillers are too expensive and unsuitable for most applications. Therefore, there is a need to develop materials that are more affordable in cost while maintaining the performance of the body material. Environmental factors will prompt the development of such materials. Product cycle evaluation as a rising concept will have a significant impact on the choice of future technologies and the choice of fillers associated with these technologies.

Classification of cooling tower packing

The classification of fillers is based on their mineral origin and chemical composition (mineral, glass, carbon black, organic matter, metal), and mineral fillers are further subdivided according to geological classification. Classification according to particle size would be beneficial because the size of the particles affects the properties of the material. However, particle size alone is not sufficient as a criterion for selecting fillers. Because different applications have different requirements. In order for the classification to facilitate the application of the filler, the classification method must include those important properties of the filler that have an impact on the final material. For example: particle size and distribution, aspect ratio, chemical composition of the surface, mechanical properties of filler particles, electrical and

Transportation and Storage of Cooling Tower Packing

Packing of filler: usually in multi-layer paper bags, bags with valves or transshipment containers. The choice of packaging takes into account the following factors: processing speed, material protection, material flow characteristics, storage space, suitability for palletization and stacking, product purity, stability, cleanliness, environmental safety and waste disposal. Transportation: Traditional modes of transportation include trains, cars, ships, etc. Trains are usually used for bulk powder, paper bags and medium bulk container transportation, and the transportation volume is generally 20~25t. Cars are mainly used for the transportation of Baozhuang filler, but bulk transportation is also growing, and bulk powder transportation vehicles can be loaded in amounts of up to 50t. Due to the need for special loading and unloading equipment, it is more complicated to transport bulk filler by ship, and fixed or mobile conveyor belt loading is commonly used. Storage: Filler storage is a complex problem. Filler can be stored in door-frame buildings, general-purpose warehouses, storage barges, storage warehouses, large hoppers and simple warehouses.

Cooling Tower Packing Expectations

1. Cost reduction Cost reduction depends on the relative cost of polymer and filler. 2. Material density Filler can increase or decrease the density of the product. 3. Optical Properties Polymer Filler The optical properties of a composite depend on the physical properties of the filler and the main components of the material, including the polymer. Color filler can change the color of the product, which will cause trouble for color matching. 5, the surface properties of the filler can make the sticky surface apart, reduce the coefficient of friction of the material. 6. Product shape The filler reduces the shrinkage of the polymer foam. 7. Thermal properties Fillers may reduce thermal conductivity. 8. Electrical Properties Volume resistivity, electrostatic dissipation and other electrical properties are all affected by the type of filler. 9, magnetic ferrite can produce ferromagnetic, used to make plastic magnets. 10. Chemical Reactivity Many fillers can affect the chemical reactions that occur due to their presence, and the reaction rate can be increased or decreased. 11. Rheological properties The rheological properties of many industrial products depend on the filler being filled. 12. Material Durability Fillers can shield radiation and can react with degradation product molecules, thereby imparting durability to the material. 13, environmental impact filler can suppress the flame, improve the spontaneous combustion temperature, reduce smoke and dust, enhance the coke effect, reduce the thermal conductivity, prevent dripping, etc., thereby delaying the fire. 14.

Role of cooling tower packing

The filler increases the viscosity of the material, especially the fiber filler increases the viscosity significantly. The filler before addition should be dehydrated to avoid consuming part of the isocyanate. It must be noted that the generation of carbon dioxide will cause the resin to foam and affect the physical properties of the polyurethane resin. In order to speed up the wetting rate of the filler and reduce the viscosity of the system, or add more fillers to the polyurethane resin, it is sometimes necessary to add a wetting or wet dispersant to the resin in advance. In-mold paint is an additive with three functions of coating, color paste and release agent. It is evenly sprayed in the mold, after the paint film is dried, you can mold polyurethane soles, self-skinning foam, polyurethane flexible foam. After the hard foam product is demoulded, the color paint is attached to the molded peripheral product. The mechanism of action of the filler: filler as an additive, mainly through its occupied volume play a role, due to the presence of filler, the molecular chain of the matrix material can no longer occupy all the original space, so that the connected chain segments are fixed to some extent, and may cause the orientation of the matrix polymer. Due to the dimensional stability of the filler, in the filled polymer, the molecular chain movement in the polymer interface region is restricted, and the glass transition temperature is increased, the thermal deformation temperature is increased, the shrinkage rate is reduced, and the elastic modulus, hardness, stiffness, and impact strength are increased. The function of filler: ① reduce the shrinkage rate of molded parts, improve the dimensional stability, surface finish, smoothness and flatness or matte of products; ② effective regulator of resin viscosity; ③ can meet different performance requirements, improve wear resistance, improve electrical conductivity and thermal conductivity, etc., most fillers can improve the impact strength and compressive strength of materials, but can not improve the tensile strength; ④ can improve the coloring effect of pigments; ⑤ Some fillers have excellent light stability and chemical resistance; ⑥ have a compatibilizing effect, which can reduce costs and improve product competitiveness in the market.
