(Reported by Wu Cunyuan and Liu Yantao.) A few days ago, the author learned from the Xinjiang Academy of Agriculture and Reclamation Crops that the new edible sunflower variety “AR7-6660†was identified by the National New Variety Identification Committee. It is understood that this sunflower variety exhibits early maturation, high yield, high quality and other characteristics in the experimental demonstration. It also has delicate taste and good taste, and can be used as an excellent roasted seeds and processed products. In addition, this variety also has the advantages of strong stress resistance, good disease resistance, and good stable production performance. It is suitable for planting in North China and Northwest China provinces.
According to reports, this species is the first sunflower white sunflower species that has been certified by the country, and it is also the first self-fertilized sunflower species that has passed the national appraisal.
Polycrystalline Diamond Compact (PDC) drill bits are designed for efficient and effective drilling in various formations, from soft to hard rock. The surface of the cylindrical-shaped PDC cutters consists of premium synthetic diamond particles sintered together by high pressure and high temperature. These cutters have high hardness, wear resistance, and great tenacity, making them ideal for drilling in oil, gas, mining, and engineering fields.
PDC coring bits are designed for use with high-powered drill rigs operating at relatively low rotation speeds. They offer several advantages over surface set bits, including faster penetration, longer drilling life, and better performance in hard rock formations.
The Q series of PDC coring bits , including BQ, NQ, HQ, and PQ sizes, are widely used for soft to medium hard rock formations. The disc-shaped cutting element's surface consists of very fine synthetic diamond particles sintered together by high pressure and high temperature. A tungsten carbide stud is brazed directly into the bit matrix, allowing the cutters to withstand the large compressive and shear loads generated during drilling .
PDC core bits are ideal for use with high-powered drill rigs operating at relatively low rotation speeds. They offer several advantages over surface set bits , including faster penetration, longer drilling life, and better performance in hard rock formations.
Two main types of PDC cutters are available: conventional flat design or dome. The flat design is suitable for general drilling applications, while the dome design is ideal for drilling in hard rock formations.
PDC drill bits are designed to provide efficient and effective drilling in various formations, with advantages including fast penetration, long drilling life, and high performance in hard rock formations. They are suitable for use in oil, gas, mining, and engineering fields and are available in various sizes and designs to suit different drilling needs.
