Cargill builds bio-based polyol plant in the United States

The United States Cargill invested US$22 million in a renewable bio-based polyol plant built in Chicago, USA, and laid the foundation on July 10.
The device will produce Cargill's proprietary soy-based polyols that will be used in place of petroleum-based chemicals to produce polyurethane products, including home upholstery, mattress foam, automotive upholstery and building insulation. The new device is expected to be put into operation in November. Cargill has now supplied its customers with renewable polyols, and the new world-scale installations will be able to meet the growing demands of Europe and the United States.
Cargill's proprietary process for the production of bio-based polyols is the conversion of carbon-carbon soluble bonds in unsaturated vegetable oils to epoxy derivatives, which are then converted to moderate temperature and atmospheric pressure. Polyol. Compared to traditional petroleum-based polyol production, Cargill's bio-based manufacturing process can reduce carbon emissions by 36% and can reduce 60% of non-renewable energy consumption.

Excavator Cylinder Piston Rod Seals

Installation and application of piston rod seal for excavator hydraulic cylinder
The installation and application of hydraulic cylinder piston rod seals in excavators mainly include the following aspects:
1. Applying lubricating oil: Before installing the seal, the surface of the piston rod must be coated with lubricating oil to facilitate the installation and use of the seal.
2. Install the seal: Install the seal on the piston rod in sequence, taking care not to pinch or bend the seal.
3. Pressing the seal: After installing the seal, special tools need to be used to press the seal tightly to ensure its tightness and stability.
4. Check the sealing effect: After installing the sealing element, it is necessary to check the sealing effect. It can be detected by observing the working status of the hydraulic cylinder or using tools such as leak detectors.
5. Application scenario: The piston rod seal of excavator hydraulic cylinder is mainly used in the hydraulic system of construction machinery such as excavators, loaders, and bulldozers to prevent hydraulic oil leakage and ensure the normal operation of the machine.
In summary, the installation and application of hydraulic cylinder piston rod seals in excavators is a very important part of the hydraulic system, and must be strictly operated in accordance with regulations to ensure the normal operation and safety of the machine.
