1、看涂料的水溶液:多彩涂料在经过一段时间的储存后,其中的花纹粒子会下沉,上面会有一层保护胶水溶液。这层保护胶水溶液,一般约占多彩涂料总量的左右。凡质量好的多彩涂料,该保护胶水溶液呈无色或微黄色,且较清晰;而质量差的多彩涂料,该保护胶水溶液或是大大超过多彩涂料总量的,或是呈混浊状态,明显地呈现与花纹彩粒同样的颜色,其主要原因不是多彩涂料的稳定性差,就是储存期已过,不宜再使用。
2、看涂料中的漂浮物:凡质量好的多彩涂料,在保护胶水溶液的表面,通常是没有漂浮物,如有也是很少量的彩粒漂浮物,尚属正常;但若漂浮物数量多,彩粒布满保护胶水溶液的表面,甚至有一定的厚度,就属于不正常了,表明这种多彩涂料的质量差。
3、看涂料的粒子度:取一个透明的玻璃杯,盛入半杯清水,然后取少许多彩涂料放入玻璃杯的水中搅拌。凡质量好的多彩涂料,杯中的水仍清晰见底,粒子在清水中相对独立,没有粘合在一起的阴阳离子,粒子的大小也很均匀;而质量差的多彩涂料,杯中的水会立即变得混浊不清,且颗粒大小呈两极分化,少部分的大粒子犹如面疙瘩,大部分的则是绒毛状的细小粒子。
4、看涂料的销售价格:凡质量好的多彩涂料,均由正规生产厂家按配方生产,价格适中;而质量差的多彩涂料,有的是厂家在生产中偷工减料,有的甚至是个人仿冒生产,成本低,销售价格比质量好的多彩涂料便宜得多。所以消费者在购买涂料的时候不要贪图价格便宜而买到质量差的涂料。
1. Look at the paint's aqueous solution: After a period of storage of colorful paint, the patterned particles will sink, there will be a layer of protective glue solution. This layer of protective glue solution, generally about the total amount of colorful paint. Where the quality of good multi-color paint, the protective glue water solution was colorless or yellowish, and more clear; and poor quality of multi-color paint, the protective glue water solution or greatly more than the total amount of multi-color paint, or in a muddy state, obviously the same color as the decorative grains, the main reason is not the stability of the multi-color coating is poor, or storage period has passed, not suitable for use. 2. Look at the floating things in the paint: where good quality multi-colored paint, in the Protection Glue Water Solution Surface, usually is not floating things, if there are also very few colored particles floating things, is still normal; but if the floating things in large quantities, color particles covered with protective glue solution of the surface, and even have a certain thickness, is not normal, indicating that the quality of this multi-color coating. 3. Look at the particle size of the paint: take a transparent glass, fill it with half a cup of water, then take a small amount of paint into the glass of water stir. Where good quality multicoloured paint, the water in the cup is still clear to see the bottom, the particles are relatively independent in the clear water, there are no anions and cations bonded together, the size of the particles is also very uniform; and the poor quality multicoloured paint, the water in the glass immediately becomes cloudy and polarized in particle size, with a few large particles appearing as lumps and a large number of small, fluffy particles. 4, look at the sale price of paint: where good quality multi-color paint, are produced by regular manufacturers according to the formula, the price is moderate; and poor quality multi-color paint, some manufacturers in the production of jerry-built materials, some even personal counterfeit production, the cost is low, the sale price is much cheaper than the good quality multicolor coating. So consumers in the purchase of paint when do not covet cheap and buy poor quality paint.
