It has been difficult to promote aqueous resins in the field of synthetic leather due to the influence of tannery production equipment. The main reason is that the latent heat of evaporation of water in the water-based resin is large, and it is not easy to dry with the conventional drying equipment, which causes the speed of the leather processing to slow down and the production efficiency is low. Therefore, most of the tanneries are reluctant to use synthetic resins to produce synthetic leather, which is a major bottleneck in the promotion of waterborne resins.
At present, China's first synthetic leather dry production line, which was independently designed and developed by the Younike Group and adopts medium-wave infrared drying technology, was successfully installed on November 28, 2009. The use of this major historical scientific and technological achievement will mark the realization that the use of safe, ecological and environmentally friendly water-based resins in China's synthetic leather enterprises will completely replace traditional oil-based resins, marking the revolutionary new technological transformation and new development in the field of synthetic leather. The official start of material promotion work.
Great develops and manufactures steel body and Matrix body coring bits using PDC cutters, thermally stable polycrystalline cutters (TSP), and combinations thereof. Diamond Coring bits is also named PDC core bits with PDC cutters and TSP cutters are designed for coring in soft, medium and hard formations, for maximum core recovery with high rate of penetration and its integrity preservation.
