Fiberglass tree grates are in the ascendant, and the existing products in shopping malls 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 fiberglass tree grates and distinguish 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 judge from four aspects:

1、 Production materials

The main production materials of 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 smooth and lubricated, with good glossiness, high strength, and a certain degree of durability. If inferior resin is used, it will be completely opposite. Inferior resin is turbid, with 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, almost no water absorption and no combustion 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, so the product strength 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, is not flame retardant, and produces boards without luster, which are relatively brittle and lack resistance.

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, we should try to choose enterprises with a long history, formal standards, and high 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 combs will also show their real strength. High quality fiberglass tree combs have a slightly dull color after a few years of use, and the entire board is intact without obvious harm. Poor quality fiberglass tree combs cannot withstand practical inspection, and after a few years of use, they will show obvious hazards such as corrosion, cracking, and porosity. 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 exhibit overall aging, which will cause significant loss.
