What are the specific requirements for the application of FRP grating in the food processing industry?
The application of FRP grating in the food processing industry has the following specific requirements:
Material requirements:
Food-grade resin: Resins that meet food hygiene standards must be used as the base material, such as food-grade unsaturated polyester resin or vinyl ester resin, to ensure that when in contact with food or in a food processing environment, no harmful substances are released to contaminate food.
Non-toxic additives: Various additives, pigments and other substances added during the production process must also be non-toxic to avoid the release of toxic components due to wear, aging and other reasons during use, which poses a threat to food processing safety.
Hygiene requirements:
Easy to clean: The surface should be smooth and non-porous to prevent food residues, stains, etc. from accumulating on the surface of the grating, breeding bacteria and affecting food hygiene. At the same time, to facilitate daily cleaning and disinfection work, conventional cleaning tools and disinfectants can be used for thorough cleaning, such as high-pressure water gun washing, chemical disinfectant wiping, etc.
Antibacterial property: In order to better ensure the hygiene of the food processing environment, some food processing sites will require FRP gratings to have certain antibacterial properties to inhibit the growth and reproduction of microorganisms such as bacteria and molds.
Corrosion resistance requirements: Food processing often comes into contact with various acidic and alkaline cleaning agents, disinfectants, and the acid and alkaline components of the food itself. Therefore, FRP gratings need to have good acid and alkali corrosion resistance, and be able to maintain the stability of structure and performance under long-term contact with these substances, without corrosion, deformation, fading, etc.
Strength requirements:
Bearing capacity: It can bear the weight of food processing equipment, goods, personnel, etc. In different usage scenarios, such as operating platforms, stair treads, cargo storage areas, etc., it must have sufficient bearing strength to prevent safety accidents such as deformation and breakage due to overload.
Impact resistance: In food processing workshops, there may be accidents such as equipment collisions and tool drops. FRP gratings need to have good impact resistance and be able to maintain structural integrity after a certain degree of impact without cracking or damage.
Anti-slip requirements: The ground and work platform of food processing workshops are usually relatively wet. In order to prevent operators from slipping and falling and ensure work safety, FRP The surface of the grille should have good anti-slip properties, such as setting anti-slip patterns and particles to increase friction.
Fire protection requirements: Food processing enterprises are usually crowded places with a large number of flammable materials, such as food raw materials, packaging materials, etc. Therefore, FRP grilles are required to have certain fire protection properties and meet the corresponding fire protection grade standards, such as low flame propagation rate and high oxygen index, to prevent the occurrence and spread of fire and ensure the safety of personnel and property.
Dimension and installation requirements:
Dimension accuracy: The appropriate size and shape should be customized according to the actual layout and use requirements of the food processing workshop, and the dimensional accuracy should be high to ensure that it can be accurately installed in the designated position, closely cooperate with the surrounding equipment and facilities, leave no gaps, prevent debris from accumulating, and facilitate cleaning and maintenance.
Installation firmness: The installation method should be firm and reliable, able to withstand the various forces during use, prevent the grille from loosening and shifting, and affect normal use and safety. It is usually installed by bolt fixing, welding, etc., and inspection and testing should be carried out after installation to ensure the installation quality.
Appearance and color requirements: Food processing enterprises usually require the facilities and equipment in the workshop to have a good appearance to keep the overall environment clean and beautiful. The color of the FRP grille should be uniform, without obvious color difference, color spots and other defects, and can be customized according to the requirements of the enterprise to distinguish different work areas or for marking warnings, etc.
