Antibacterial masterbatch for PE greenhouse film effectively prevents green moss
Using antibacterial masterbatch for PE greenhouse film to prevent moss is an effective and feasible solution. The following is an analysis from the aspects of principle, product features and application effects:
The principle of antibacterial masterbatch in preventing moss growth
Antibacterial masterbatch plays a role in the plastic processing and molding process by uniformly dispersing antibacterial agents in the base resin to form a concentrated body. Taking the antibacterial and antifungal masterbatch prepared by loading inorganic zinc-based antibacterial agents and organic antifungal agents on EVA as the carrier as an example, it can be directly mixed with raw materials for injection molding or foaming use. Among them, the inorganic zinc-based antibacterial agents and organic fungicides can inhibit the growth of algae and other microorganisms, thereby preventing the growth of moss on the surface of the greenhouse film.
Features of antibacterial masterbatch products
Strong antibacterial and antifungal performance: The antibacterial and antifungal masterbatch has a powerful inhibitory effect on various harmful microorganisms. For instance, the antibacterial rate against harmful microorganisms such as Escherichia coli and Staphylococcus aureus reaches over 99.9%, and the antifungal effect is at level 1 or 0, effectively preventing the growth of microorganisms like moss.
Wide range of applicable materials: It is suitable for various materials such as PP, PE, ABS, PVC, EVA foam, PS, PA, PC, etc., and can meet the production requirements of different types of PE greenhouse films.
Easy to use: It exists in the form of white or off-white particles, which is convenient for storage, transportation and processing. During the production process of PE greenhouse film, it is only necessary to mix the antibacterial masterbatch with PE resin in a certain proportion, without the need to add additional antibacterial agents, which simplifies the production process.
Practical application effect
Reducing the growth of moss: In a greenhouse environment, due to high humidity and suitable light conditions, moss is prone to grow on the surface of the greenhouse film. The use of PE greenhouse film with antibacterial masterbatch added can effectively inhibit the growth of moss, keep the greenhouse film clean and transparent, increase the light transmittance of the greenhouse, and be beneficial to the photosynthesis of crops.
Extending service life: The growth of microorganisms such as moss can cause corrosion and damage to the greenhouse film, shortening its service life. The anti-moss effect of antibacterial masterbatch can reduce this kind of damage, extend the service life of PE greenhouse film and lower the replacement cost.
