Nowadays, guardrails have become essential building materials in our daily lives. They can be used to construct everything from small courtyards, parks, schools to roads, bridges, and scenic spots, and are very common. Among them, the imitation stone and imitation wood guardrails are the most special, because these two types of guardrails have almost the same appearance as stone guardrails, but are actually made of different materials. This is because of a special coating, professionally known as imitation stone coating or colorful coating. Moreover, compared to stone guardrails, stone guardrails have higher cost-effectiveness, more diverse shapes, easier production, and simpler installation. For example, imitation stone metal guardrails, imitation bluestone guardrails, antique style guardrails, etc. Next, we will briefly share several ways to distinguish the advantages and disadvantages of imitation stone coatings< br />
Distinguishing the advantages and disadvantages of imitation stone colorful coatings
1. Look at water solubility. After a period of storage, the pattern particles in colorful coatings will sink and there will be a protective adhesive solution on the surface. This protective adhesive solution usually accounts for about 1/4 of the total amount of colorful coatings. For high-quality colorful coatings, the protective adhesive solution should be colorless or slightly yellow and clear; However, for low-quality colorful coatings, the protective adhesive solution presents a turbid state, clearly showing the same color as the patterned particles. The main problem is either poor stability of the colorful coating or expired storage, making it unsuitable for reuse< br />
2. Look at floating objects. Any high-quality colorful coating usually has no floating particles on the surface of the protective adhesive solution, with very few floating particles; But if there are a large number of floating objects, colored particles covering the surface of the protective adhesive coating, and even a certain thickness, it is not normal. Its appearance indicates that the quality of this colorful coating is poor< br />
3. Check the particle size. Take a transparent glass, pour in half a cup of water, then take a small amount of stone like colorful paint and stir with the water in the glass. For high-quality imitation stone colorful coatings, the water in the cup is still clear and visible, and the particles are relatively independent in clear water, without bound anions and cations. The particle size is very uniform; However, for low-quality imitation stone colored coatings, the water in the cup will immediately become turbid and unclear, and the particle size will be differentiated. A small number of large particles are like bumps, while the majority are small, fluffy particles< br />
4. Look at the selling price. High quality imitation stone colorful coatings are produced by legitimate manufacturers according to the formula, with moderate prices; Poor quality coatings, some of which are cut corners in production, and some are even counterfeited by individuals, have low costs and much cheaper sales prices than high-quality coatings. If customers try to save money, they will be tempted by small discounts and suffer big losses< br />
