It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

In construction, the 20mm drill rod plays a crucial role in the installation of foundations, retaining walls, and other structural elements. It is often used in conjunction with augers to excavate soil, providing essential support for various types of construction projects. Additionally, the rod can be deployed in trenching operations, making it a versatile tool for civil engineering applications.
Recent advancements include the development of smart slurry pumps equipped with sensors that monitor pump performance in real-time. These sensors can provide data on flow rates, pressure levels, and wear patterns, allowing for predictive maintenance and minimizing unexpected failures. Moreover, advances in materials science have led to the creation of more resilient pump components, extending service life and reducing the frequency of replacements.
Brand reputation plays an essential role in the pricing of drilling machines. Well-established brands with a history of producing high-quality, reliable equipment often command higher prices than lesser-known manufacturers. However, investing in a reputable brand can provide long-term benefits, including better after-sales support, availability of spare parts, and a warranty. Cheap equipment might save money in the short term, but it could lead to higher maintenance costs and lower productivity over time.
Чулуу бутлуурын бүтцийн талаар ярихдаа, плита нь нийтдээ хоёр үйлдэлтэй - нэг нь бутлах, нөгөө нь жийгдэх үйлдэл. Эхний үйлдэл нь өндөр даралтаар чулууг таслах бөгөөд хоёрдахь үйлдэл нь жижиг хэсгүүдийг цуглуулах, боловсруулах зориулалттай. Плитагийн дотоод бүтэц нь блок, хагас хагас, тал дундын хэлбэртэй байх боломжтой бөгөөд энэ нь түүний гүйцэтгэлд нөлөөлдөг.
