Phthalic Anhydride Polyester Polyol
Polyester Polyol is a type of polyol that is derived from the reaction between a polyol (such as glycerol or ethylene glycol) and a dicarboxylic acid (such as adipic acid or phthalic anhydride). It is commonly used as a raw material in the production of polyurethane foams, coatings, adhesives, and elastomers.
Polyester polyols have several advantages over other types of polyols. They have good chemical resistance, mechanical properties, and thermal stability. They also have low toxicity and are environmentally friendly. Additionally, polyester polyols can be easily modified to achieve desired properties, such as increased flexibility or flame retardancy.
Polyester polyols are typically liquid at room temperature and have a high molecular weight. They can be further reacted with isocyanates to form polyurethane materials, which have a wide range of applications in various industries, including automotive, construction, and furniture.
Polyurethane packaging foam is a type of foam material that is commonly used for packaging and cushioning products during shipping and transportation. It is made from polyurethane, a polymer that is created through a chemical reaction between polyols and diisocyanates.
Polyurethane packaging foam is known for its excellent shock absorption and cushioning properties. It is lightweight and can be easily molded into various shapes and sizes to fit the specific needs of the product being packaged. The foam is also resistant to moisture, chemicals, and oil, making it suitable for protecting products in various environments.
There are two main types of polyurethane packaging foam: flexible foam and rigid foam. Flexible foam is soft and pliable, providing cushioning and protection for fragile items. Rigid foam, on the other hand, is more dense and firm, providing structural support and protection for heavier items.
Polyurethane packaging foam can be custom-made to meet specific requirements, such as density, firmness, and compression strength. It is widely used in industries such as electronics, automotive, furniture, and medical equipment, where protection and safety during transportation are crucial.
Overall, polyurethane packaging foam is a versatile and effective material for protecting products during shipping and transportation, ensuring that they arrive at their destination in good condition.

In order to verify the reliability of the products, the American Nabors engineers and the third-party inspectors hired by the company accepted the two sets of FKDQ1200-9 electro-hydraulic control devices ordered by the company. The American acceptance personnel were very satisfied with the design and quality of the products. At present, Beijing Petroleum Machinery Factory has received 10 sets of orders for electric hydraulic control devices.
Ground BOP control devices are a very important core device in drilling control systems. Beijing Petroleum Machinery Factory has been designing and manufacturing liquid control device products for more than 20 years. It has become the largest manufacturer with the largest output and the widest product coverage. Since the beginning of this year, nearly 30% of the orders for liquid control devices have been exported, and the products have been ordered by well-known companies such as National, Cameron and Nabors.
The first domestic BOP electric hydraulic control device was successfully developed in Beijing Petroleum Machinery Factory. This product is mainly composed of a remote console, an HMI operation panel (a Siemens 15-inch touch screen is installed on the stainless steel cabinet) and a control cable. Compared with the traditional BOP control device, the remote control driller, multi-function alarm device, touch screen is used as the man-machine interface, the UPS system is added, and different BOP combinations can be selected to facilitate multiple remote control. The operation and operation are simpler and more transparent, the motor starts and stops more accurately, and the reaction speed is fast.
