Metal Cutting Fluids
Metal Cutting Fluids

Today, modern cutting fluids are subjected to a variety of demands. Therefore, metalworking fluids (MWFs) play a crucial role in the metalworking industry that cutting fluids must be effective, economical, and free from ingredients that are harmful to health and the environment.The properties that are sought after in a good cutting fluid are the ability to: ■ Keep the workpiece at a stable temperature. ■ Prevent rust on machine parts and cutters. ■ Maximize the life of the cutting tip by lubricating the working edge and reducing tip welding. ■ Ensure safety for the people handling it (toxicity, bacteria) and for the environment upon disposal.Broadly there are four types of cutting fluids – soluble (emulsion), semi-synthetic, synthetic & neat oils. Each type is defined by the amount of mineral oil it contains. Soluble cutting fluids contain the most mineral oil, while semi-synthetic cutting fluids contain lower amounts of oil, and synthetic cutting fluids contain no mineral oil. Next, we are going to introduce these metalworking oils about their difference and functions.

Industrial Lubricants
Industrial Lubricants

Lubricants are mostly used to lessen the wear and tear of material while reducing binding and friction. The lubricants are ideal because of its properties. It can prevent corrosion from both inner and outer surfaces where they are applied. Many processes only run smoothly with specially-made lubricant solutions. Safety, machinery, processes and systems in particular must be taken into consideration here.

Rust Preventive Oil
Rust Preventive Oil

MORESCO and WILL rust preventive oils range has been designed to effective protection of parts and components which is used for protection between operations or for a final anti-corrosion protection before dispatch or storage.Hai Lu Jya He (HLJH) manufactures rust preventive oils and provide solutions to protect metals from rust and corrosion for short-term, medium-term or long-term protection. Our anti-rust oils have been verified by means of a salt spray test(6~48 hours) that it have excellent metal adherence properties and protects all metals from corrosion during open-air storage and transport. It can be applied by spraying - micro-spraying, sprinkling, or immersion, leaving a protective anti-corrosion film that is waxy, oily, greasy and with high de-watering power that effectively protecting exposed metal surfaces.

Wastewater Treatment
Wastewater Treatment

Wastewater treatment is the process of converting wastewater that is no longer needed or is no longer suitable for use. These treatment aims at reducing the contaminants to acceptable levels to make the water safe for discharge back into the environment. Most of the wastewater from industries contains chemicals and other toxins that can largely harm the environment.
