1) watertight floor
2) water tightness
Comparing with the traditional patching method of using small plates and L-bolt with the help of chain hoist, this technique deploys a complete steel plate and chain block to patch a big hole underwater, which would reduce the workload of the divers, improve work efficiency, and ensure the structural strength as well as the water tightness after completion.
3) washing water density
4) water sealing
The original creation of this modification is the water sealing between pallet side plates and exhaust hood.
5) soft water
Design of soft water system of closed circuit and its application in iron-smelting furnace;
6) density of oil and water
