Fiberglass tree grates have not yet emerged, and the existing products in the shopping mall are of mixed quality, with varying levels of quality, bringing many negative impacts to a wide range of users. In order for us to better understand the production and quality of fiberglass tree grates, briefly introduce how to distinguish the production and quality of fiberglass tree grates.

When choosing fiberglass tree grates, we can conclude from four aspects:

1、 Production materials

The primary production materials for fiberglass tree grates are resin, fiberglass fibers (abbreviated as fiberglass), and filling powders.

1. Resin. High quality fiberglass tree grates are made of high-quality resin: unsaturated ortho benzene resin 196, colorless and transparent. Low viscosity, low heat release, low shortening, high-speed curing, high-speed compatibility, and bright glossiness. The produced fiberglass tree grates are flat and smooth, with good glossiness, high strength, and certain durability. If inferior resin is used, it will be completely opposite. Inferior resin is turbid, high viscosity, high heat release, high shortening, relatively slow curing, and poor compatibility. The produced fiberglass tree grates have many pores, are prone to cracking, and have poor strength and resistance.

2. Fiberglass filament (abbreviated as fiberglass). Fiberglass fibers can enhance the durability of the grating in fiberglass tree grates. High quality fiberglass fibers, such as alkali free fiberglass fibers, have higher strength than steel wires and have certain resistance, chemical stability, good weather resistance, and almost no water absorption or burning when exposed to fire. Its high strength can also be used as tire cord. The fiberglass fibers of the 1220 * 2440 * 38 standard fiberglass tree grate are laid in 8-9 layers, ensuring the strength of the product is guaranteed. Some manufacturers use fiberglass fibers with high alkali fibers as alkali free fibers, which have lower strength and poor water and alkali resistance.

3. Filling powder. The filling material for fiberglass tree grates is aluminum powder. The high-quality filling material is delicate and bright white, with flame retardancy and complete fusion with resin. The produced boards have beautiful colors, good transparency, and high durability. On the contrary, low-quality filler powder such as calcium powder is rough and dull, easily swells when absorbing water, and is not flame retardant. The resulting board lacks luster and is relatively brittle and lacks durability.

2、 Production process

The production method of fiberglass tree grates is semi machine and semi manual. The nature, proficiency, and production process requirements of the production process personnel (such as the number of fiberglass layers and the proportion of filling materials) will have a significant impact on the quality of fiberglass tree grates. Therefore, please try to choose enterprises with a long history, formal production, and large production volume.

3、 Comparison of products

High quality fiberglass tree grates have no obvious cracks in appearance, fewer pores, bright and simple colors, good transparency, and certain durability. They have high strength, good surface smoothness, and long service life; However, low-quality fiberglass tree grates have cracks on the appearance, numerous pores, and impure color, which is not suitable for glossiness. Its lifespan is also relatively short.

4、 Practical application effect

Practice is the only criterion for verifying truth, and time is also the most fair judgment. In the practical application process, fiberglass tree grates will also show their real strength. High quality fiberglass tree grates have a slightly dim color after being used for a few years, and the entire board is intact without obvious harm. Poor quality fiberglass tree grates cannot withstand practical inspection, and after a few years of use, obvious hazards such as corrosion, cracking, and porosity will appear. The board is not so flat, and the color degradation is severe, resulting in overall aging, Generally, fiberglass tree grates need to be used for twenty years, but after two years, low-quality fiberglass tree grates will experience overall aging, resulting in significant loss.
