Big Five
First, buy the most heavy
Lift the paint bucket and shake it. If there is a crackling sound, it means that the packaging is seriously inadequate. There are two shortages of gins, and the viscosity is too low. The formal factory is real and does not hear the sound.
Second, buy the least consumption
Consultation with merchants about the number of painting passes and the area of ​​painting, the amount of calculation and the cost per square meter of material are not deceived by the price of each group (barrel), the unit price is low, and the consumption is particularly large. It is more expensive and wasteful. , And the quality is poor.
Third, buy a professional supporting strong
Good quality products are often more professional, and provide technical guidance and after-sales services, including pre-sale consulting, construction guidance and advice in the sale, after-sales maintenance, etc., Moreover, the regular manufacturers provide colorful model colors .
Fourth, buy information is complete
There are clear trademarks, origins, contact telephone numbers, net weights, corporate commitment standards, etc. on the packaging of the genuine paint, and its website can be opened. The no-name paint is often marked with fake addresses, telephones and websites.
Fifth, buy "trustworthy enterprise"
The trustworthy enterprises are directly purchased from the market by government agencies, and only if there are no complaints during the entire year will they be on the list.
Three principles
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 paints account for about 45% of our paint market, and they mainly occupy our high-end market. Their prices are 20% 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.

One of the most fascinating materials of our time is polycrystalline cubic boron nitride PCBN - the second hardest material after diamond. At CeramTec, PCBN is used as a cutting material from which indexable inserts are manufactured for machining.
PCBN is produced synthetically and is a "composite material" made of cubic boron nitride and a mostly ceramic binder phase. The ratio of cBN to binder content and the cBN grain size determine the application.
PCBN cutting materials are used in the machining of hard and/or highly abrasive workpiece materials. The high hardness and the extremely high hot hardness (up to temperatures above 1,000°C), the edge stability and inertness towards ferrous materials as well as the basically good chemical resistance give CBN cutting materials a high potential for use in machining. On the cutting material side, a distinction is made between high- and low-cBN cutting material grades.
PCBN (Polycrystalline Cubic Boron Nitride) blanks for cutting tools are composite ultrahard materials sintered by polycrystalline CBN and carbide alloy under ultra-high pressure and high temperature conditions. They combine the hardness, wear resistance, and thermal stability of CBN with the impact resistance and toughness of carbide alloy. PCBN blanks are highly suitable for cutting ferrous and non-ferrous metals with high hardness.
