Article Summary: The resin has excellent process performance, which has its outstanding advantages. It has a suitable viscosity at room temperature, can be formed at room temperature and normal pressure, and is convenient to construct. It is particularly suitable for the production of FRP products, but in actual operation There are many factors that affect its performance, which is worthy of our attention. Factors affecting the performance of the resin: 1. The gelcoat resin manufacturer introduces that the resin is mixed in the synthesis process...
The resin has excellent process performance, which has its outstanding advantages. It has a suitable viscosity at room temperature and can be formed at room temperature and atmospheric pressure. It is convenient to construct and is particularly suitable for the production of FRP products. However, in actual operation, it will There are many factors that affect its performance, which is worthy of our attention.
Influencing factors of resin performance:
1. Gelcoat resin manufacturers introduce substances with a low degree of polymerization that are included in the resin during the synthesis process, and substances generated by the decomposition of the resin, which will be dissolved during the operation. Resins with a low degree of crosslinking and many active groups have a greater tendency to dissolve.
2. The ion exchange resin contains a large number of hydrophilic groups, which will swell upon contact with water. When the ions in the resin change, for example, the cationic resin changes from H+ to Na+, and the anion resin changes from Cl- to OH-, all expand due to the increase in ion diameter, increasing the volume of the resin.
Influencing factors of resin performance: Generally, resins with low cross-linking degree have a larger degree of swelling. When designing an ion-exchange device, the degree of expansion of the resin must be considered to accommodate the resin volume change that occurs during ion conversion in the resin during production operation.
3. Ion exchange resin particles have transfer, friction, expansion and contraction changes during use. After long-term use, there will be a small amount of wear and breakage, so the resin must have high mechanical strength and wear resistance. Generally, resins with a low degree of cross-linking are more fragile, but the durability of the resin is mainly determined by the uniformity and strength of the cross-linked structure.
In fact, if classified according to specific special varieties, the resin includes winding resin, spray resin, RTM resin, gel coat resin, pultrusion resin, SMC, BMC resin, flame retardant resin, food grade resin, anti-corrosion resin, air-drying resin , Polaroid resin, etc., can be used to make car shells, bathtubs, cooling towers, storage tanks, etc.
