Oil-absorbent felt is an important tool for managing oil spills. In the emergency treatment of oil spills on water surfaces, the common method is to first recover most of the spilled oil by mechanical means, and then use oil-absorbent felt to absorb and capture the small amount of oil spilled into the water. surface. Oil-absorbent felt is often used to remove oil spills where mechanical devices cannot reach and in water where oil spill dispersants cannot be used due to sensitivity to secondary contamination.
Felt is made of natural wool, machined, and bonded using the milled properties of wool. The felt has good flexibility can reach certain lengths and can be used for leather dynamic belts and papermaking suction belts. Felt has good heat retention and can be made into felt insoles to specifications.
The manufacturing process of the oil-absorbing industry felt:
1. Take an appropriate amount of wool, fold the wool in half, and roll it gently to form a fluffy cylinder.
2. Overlap the two ends of the fluffy cylinder inwards, place it on the work pad, and poke it lightly to fix it.
3. Punch while rolling, being careful not to tear your hands.
4. During the felting process, it is necessary to keep the ball rolling to avoid deformation.
5. When you feel resistance during the jab, the hairball is already half-felt. At this time, the wool ball can be repaired, including depression, expansion, etc.
6. After the repair is completed, felting can be continued until the hairball is firm.
Oil-absorbent felt warp is not woven, so it has good filterability and can be used for oil absorption. Most of the bottom of a ship's oil drum is made of felt to keep the ship clean. After flocking and bonding, it can be used separately according to density size and different properties. It has good heat insulation performance and can be used as a heat insulation material. Good bonding performance is not easy to loosen and can be punched into different-sized parts.
