What resins are used by FRP grill manufacturers
Ta Tou 2019-01-04 11:06
The FRP grill manufacturers will talk to us about the resins and their characteristics used in the production of FRP grills. Let ’s take a look together.
First of all, resin refers to an organic polymer that has a softening or melting scale after being heated, and has a tendency to flow under external force during softening. It is solid, semi-solid at normal temperature, and sometimes liquid. Resin is an important raw material for the production of FRP gratings.
The resin plays the role of corrosion resistance and adhesive in the surrounding glass fiber reinforced plastic products. The fiber is integrated by the resin's bonding. The resin transmits the force to the fiber, so that one bears the load at the same time. The quality of aging resistance determines the quality of FRP's corrosion resistance, temperature resistance and aging resistance. Therefore, the selection of appropriate resin is an important prerequisite to ensure product quality and safe use.
There are three common resins used to produce FRP gratings:
A, 196 resin, there are 10 layers of 38 alkali-free yarn, the compressive strength is very high, and the surface is beautiful, the color can be arbitrarily selected, and it can be used for more than 10 years.
B. General 191 resin, 8 layers of 38 alkali-free yarn, relatively high compressive strength, beautiful surface and colorful, the service life is about 6 years.
C. General 191 resin, 8-layer 38 high-alkali yarn, with relatively high compressive strength, beautiful surface and bright colors. The service life is about 3 years.
The characteristics of FRP grids produced by using different resins are not the same. The strength of 196 resin is high and the effect of yarn penetration is also good. 191 resin is the general resin, the price is relatively cheap, and the resistance is slightly worse.
We first analyze from the characteristics of FRP grid:
First, the FRP grating is corrosion-resistant, acid- and alkali-resistant, and highly resistant to various organic solvents such as strong acids and alkalis.
Second, it is safe from moisture, good water resistance, stable function, and aging resistance.
Third, high temperature resistance and flame retardant, zui high can withstand open flame temperature of about 1400 ℃.
According to the introduction of the FRP grid manufacturer , a conclusion is drawn based on the above analysis: The storage environment requirements of the FRP grid plate are not high, and generally it can be placed in a dull environment. Several aspects to keep in mind of storage needs:
1. It is forbidden to store in explosive and flammable environment. Although the FRP grille board has a high temperature resistance, it is strictly forbidden to place it in explosive places due to the safety guidelines.
Second, do not keep with chemical raw materials. Although it has high corrosion resistance, paints, colorants and other chemicals can easily cause pollution to the glass fiber reinforced plastic grille panel, so it should not be put together.
3. Regular cleaning. The scouring operation is relatively simple. It only needs to be washed with water, and no chemical cleaning agent is needed for cleaning.
