Patent number: 6322622Abstract: A flame spray mending material effective for applying a dense thermal spray mending layer to a silica brick wall of an industrial furnace, having a high crystallization ratio immediately after thermal spraying in a broad thermal spray condition, having an oxide concentration of 89% by weight or more of SiO2, more than 2.0 to 4.0% by weight of Na2O and/or more than 0.2 to 4.0% by weight of Li2O, having a 80% or more crystallization ratio after thermal spraying and 200 kgf/cm2 or more compression strength. A slight amount of CaO may be present to make a flame spray mending material with an oxide concentration of 89% by weight or more of SiO2, more than 2.0 to 5.0% by weight of CaO, 0.5 to 4.0% by weight of Na2O and/or more than 0.2 to 4.0% by weight of Li2O, and 1.0% by weight of less of Al2O3.Type: GrantFiled: November 26, 1999Date of Patent: November 27, 2001Assignee: Kawasaki Steel CorporationInventors: Hisahiro Matsunaga, Masato Kumagai, Yasumasa Fukushima

Patent number: 6294006Abstract: An anticorrosive and antifouling additive for paints, which is effective to protect structures such as steel ships and pipes from rust, and prevent the adhesion of marine organisms and algae to the structures used in seawater without adversely affecting the marine environment, and a paint containing the same additive are provided. The additive comprises 70 to 94% by weight of at least one selected from the group consisting of bastnasite, monazite and Chinese complex mineral, 3% by weight or more of tourmaline, and 3% by weight or more of zircon, with respect to the total amount of the additive. The additive emits a required amount of negative ions to achieve the effect of preventing the adhesion of marine organisms and algae and prevents the occurrence of rust. In practical use, the additive can be added to a conventional paint in an amount of 8 to 15% with respect to paint weight.Type: GrantFiled: October 11, 2000Date of Patent: September 25, 2001Assignee: Nazca Co., Ltd.Inventor: Hiroshi Andou
