Putty is an important substrate of paint, which directly affects the quality of wall paint, and should be given enough attention.
Principle 1: Buy only what you need
It is difficult to say which kind of coating is cost-effective and the key is its own needs. At present, the properties of paints are mostly concentrated on scrubbing, mildew proofing, antibacterial, and covering fine cracks, etc. The price of paints also increases with the increase of functions. Before buying, think about your needs first. The most expensive ones are not necessarily useful to you. For example, some scrubbing times can reach more than 20,000 times, and some are 3,000 times. The price of the former is naturally much more expensive. However, the state stipulates that the number of rubbing resistances as long as it has reached 1000 times is qualified, so whichever one of you choose depends on your own Needed; Another example is, some houses are sunny, well ventilated, and the function of anti-mildew must not be wasted.
Principle II: Do not believe in advertising
Clear up the cloud of paint advertisements, and directly request relevant testing methods, testing standards, and authoritative testing agencies to verify the authenticity of the product. For example, the so-called nano-coatings are unworthy of their name, and there are no internationally recognized testing standards.
Principle 3: Let go of your hands and feet
At present, imported coatings account for about 45% of our coating market, and they mainly occupy our high-end market. Their prices are 20%-50% more expensive than domestic coatings. However, the testing results of 10 Chinese and foreign paint brand comparison tests released by the National Chemical Building Materials Testing Center in 2003 prove that Fuya, Jiabaoli, and Qianxiehua are comparable in quality to foreign brands such as Nippon and Dulux.

Fused Silica features high transmission from 200nm to 2.2μm with a low coefficient of thermal expansion, making it ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Ball lenses are commonly used for improving signal coupling between fibers, emitters, and detectors, as well as objective lenses in endoscopy and bar-code scanning applications. Half-ball lenses simplify handling and integration.Half ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.
