PDC (Polycrystalline Diamond Compact) cutters are crucial components used in drilling operations across various industries, including oil and gas exploration, mining, geothermal drilling , and construction. These cutters are renowned for their exceptional hardness, wear resistance, and thermal conductivity, making them ideal for cutting through hard rock formations encountered during drilling . PDC cutters are composed of a polycrystalline diamond layer bonded to a tungsten carbide substrate under high pressure and temperature. This composite material combines the hardness and wear resistance of diamond with the toughness of tungsten carbide, resulting in a highly durable cutting tool. These cutterstypically have a flat or slightly curved cutting surface with diamond cutting elements arranged in a pattern. The cutting surface is optimized for efficient material removal during drilling operations. PDC cutters are used in a wide range of drilling applications, including oil and gas drilling , mining, geothermal drilling , and construction. They are employed in various drilling tools, including PDC bits, core bits, hole openers, and reamers. The performance of PDC cuttersplays a crucial role in determining the overall efficiency and success of drilling operations. Factors such as cutters design, quality, and maintenance significantly impact drilling performance and tool longevity. Therefore, selecting the right type of PDC cutter for specific drilling conditions and applications is essential for achieving optimal results.

Ushered in September, is also a small period of decoration, this time more decoration, pay attention to some paint coating methods. The paint is the last part of the wall decoration. The use of inferior paint not only affects the aesthetics of the home, but also does not guarantee the yellowing or cracking of the paint. Since there is no obvious difference in the appearance of the paint, first introduce some simple shopping methods:
The most important thing is to buy the packaging: lift the paint bucket and shake it. If there is a crackling sound, it means that the packaging is seriously lacking, and there are two shortages, and the viscosity is too low. The regular factory material is real and it is almost inaudible. .
Buying the least amount of consumption: Consult the merchant for the number of painting passes and the area for painting, the amount of calculation and the cost per square meter of the material, not deceived by the unit price of each group (barrel), paint from solids (film forming) And the composition of volatiles, high solids content of 70% to 80%, low of less than 10% to 20%, the unit is often very large consumption of large, more expensive and more cost-effective to calculate, and poor quality.
Buy professional and strong support: good quality products are often more professional, according to the plate texture, color, structure or use of objects with different designs and strict process requirements, and provide technical guidance and after-sales service, regular manufacturers are Provide colorful color model card.
Buying business-led: The best-selling level of the product, whether it is dominant, whether the position of the shelf is prominent, and the size of the furnishings can be inferred.
Precautions:
Try to choose a brand of paint. There are often advertisements on TV and no further introduction. When you buy paint, do not talk to the painter to buy the paint. Look for the approximate amount of use. Go to the store to buy it. Don't tell the store's information about the construction work.
If you do not choose brand paint, then I suggest that you pay attention to the place of paint production when purchasing: At present our paint on this market is divided into two major production areas (how do you know about other places), Shanghai, Zhejiang and Zhejiang provinces, and mine The suggestion is to choose Guangdong goods, because in the process of my construction, I feel that the same price of paint Guangdong goods is better.
Look for “green†environmentally-friendly products. Note that the various paints and coatings currently sold are all marked with the word “greenâ€. Can "green" building materials currently on the market not necessarily be environmentally friendly? What kind of product is a "green" environmental product? Is it equal to the national standard is equivalent to environmental protection products? The confirmation of green products should be confirmed by the National Certification and Accreditation Administration Committee. When purchasing green home improvement building materials, it is necessary to recognize the “Ten Ring†icon of the Chinese environmental label. This is also the easiest and most effective method to identify the authenticity of “green productsâ€.
Look at the weight, do not sloppy, the market has a wide range of paint packaging specifications, in our, the lightest is 3 kg, the most important is 9.5 kg. You should pay attention to when you purchase, there are two types of 5 kg, 5 kg in gross weight and 5 kg in net weight. I think it should be clear which one to choose.
Xiao Bian concluded: decoration is not a sloppy thing, a lot of details of the relationship to the future occupancy. Choose a good paint coating to avoid the impact of some bad products on the home, learn to buy these methods is to master some of the buying skills.
