DEVELOPMENT OF BACTERIA SLIME-BASED CONCRETE PROTECTIVE COATING MATERIAL
The present invention provides, as a bacteria slime-based coating material using bacteria capable of forming slime, a coating material comprising an adsorbent on which slime-forming bacteria are adsorbed, and a binder. According to the present invention, an optimal slime-forming bacteria and optimal slime-forming conditions that take concrete chemical resistance into consideration; an optimal adsorption method for a viable autotrophic environment for bacteria, rather than simple injection, during the blending of an existing concrete; a technique for utilizing an optimal binder having a pH of about 8-10 in consideration of bacteria growth environment; and a method which is economical compared to a prior art technique of injecting bacteria and enables easy and substantial adsorption of a large quantity of bacteria may be provided. Also, a novel coating material that enhances concrete chemical resistance and durability and takes into consideration the mechanisms involved in the chemical erosion of a concrete sewer and the mechanisms involved in the resistance of slime-forming bacteria to sulfuric acid may be provided.
La présente invention concerne, en tant que matériau de revêtement à base de biopellicule de bactéries utilisant des bactéries capables de former une biopellicule, un matériau de revêtement comprenant un adsorbant sur lequel des bactéries formant une biopellicule sont adsorbées et un liant. La présente invention concerne une bactérie optimale de formation de biopellicule et des conditions optimales de formation de biopellicule qui prennent en considération une résistance chimique du béton; un procédé d'adsorption optimal pour un environnement autotrophe viable pour des bactéries, plutôt qu'une injection simple, pendant le mélange d'un béton existant; une technique d'utilisation d'un liant optimal présentant un pH d'environ 8-10 tenant compte de l'environnement de croissance des bactéries; et un procédé qui est économique par rapport à une technique antérieure d'injection de bactéries et qui permet une adsorption facile et substantielle d'une grande quantité de bactéries. L'invention concerne également un nouveau matériau de revêtement qui améliore la résistance chimique du béton et la durabilité et qui prend en considération les mécanismes impliqués dans l'érosion chimique d'un égout en béton et les mécanismes impliqués dans la résistance à l'acide sulfurique de bactéries formant une biopellicule.
슬라임 형성이 가능한 박테리아를 이용한 박테리아 슬라임 기반의 코팅재로서 본 발명은 슬라임 형성 박테리아를 흡착시킨 흡착재 및 결합재를 포함하는 코팅재를 제공한다. 본 발명에 따르면 콘크리트 내화학성을 고려한 최적의 슬라임 형성 박테리아 및 최적의 슬라임 형성 조건과, 기존 콘크리트 배합 시 단순 투입이 아닌 박테리아 자가영양 생존환경을 위한 최적의 흡착방법과, 박테리아 생장환경을 고려한 pH 8~10 수준의 최적 결합재의 활용 기술과, 박테리아 투입을 위한 종래기술에 비해 경제적이고 다량의 박테리아를 용이하면서도 실질적인 흡착이 가능하도록 하는 방법을 제공할 수 있고, 콘크리트 하수관거의 화학적 침식에 대한 메커니즘과 슬라임 형성 박테리아의 내황산성 메커니즘을 고려한 새로운 개념의 콘크리트 내화학성과 내구성을 향상시키는 코팅재 기술을 제공할 수 있다.
