Nowadays, with the development of the market, China’s FRP industry shows a trend of jump growth, the market demand for FRP grating is also increasing. More and more grille manufacturers, some bad businesses in order to make huge profits and use inferior raw materials, resulting in uneven quality of grille products, many customers and friends are cross-stitch eye, today hui Ze FRP with an intuitive way to teach you to distinguish.
one
Observe the appearance of FRP grating
This is the most direct identification method, if the grille product appearance is smooth, less pores, no cracks, no blocks, then the grille product is better; On the contrary, if the product surface rough, block, crack, more pores, so, the quality of the product is much worse. Quality grille appearance has the following characteristics:
1, the surface of good quality FRP grating is smooth and bright, very smooth to touch by hand, and the touch is good;
2, high quality grille has no strong smell, there is a light varnish smell;
3, FRP grating products with a little bit of bubble is better, which means the use of high quality resin, because the density of good resin is larger, so there will be fewer small bubbles.
Physical test
1, product bearing test: this is a more intuitive method, the site of the grid plate load test, see whether the grid deformation, observe the bearing capacity of the product.
2, beating the outer wall of FRP grating, if clear, that the resin material, on the contrary, if the sound of beating is dull that the amount of resin is less, more calcium powder, the quality of the product is relatively poor.
