The pieces of wood are sterilized and dried and absorbs moisture.
Abstract:
PURPOSE: A poultice for removing metal pollutants from the surface of a porous cultural heritage and a method thereof are provided to clean off metal pollutants from a localized region of a porous cultural heritage with a small amount of cleaning agent. CONSTITUTION: A poultice for removing metal pollutants from the surface of a porous cultural heritage comprises oxalic acid as flux and a poulticing material. The poulticing material is bentonite, sepiolite or active carbon fiber. The poulticing material and oxalic acid are mixed at a weight ratio of 1:3-5.
Abstract:
PURPOSE: A composition of a complex earth wall with heat insulation function and a construction method thereof are provided to improve insulation effect and prevent a gap between inner and outer walls. CONSTITUTION: A construction method of a complex earth wall with heat insulation function is as follows. A heat insulating material form(14) formed inside the complex earth wall is prepared and a heat insulating material(13) is inserted therein. Stiffeners(10) are formed in a grid format so as to couple and support inner and outer earth walls(12,11) by passing through the heat insulating material form in which the insulating material is inserted. An inner wall form(16) and an outer wall form(15) are formed on both sides of the heat insulating material form to construct an inner wall and an outer wall rammed earth method and earth concrete method, respectively. The forms are removed from the completed complex earth wall.
Abstract:
PURPOSE: A finishing construction method of a soil wall, and a finishing composition of the soil wall are provided to secure the environment-friendly property including the indoor air quality improvement function of soil, and to avoid using silicon or harmful chemical substances for the human body. CONSTITUTION: A finishing construction method of a soil wall using an environment-friendly water repellent comprises the following steps: soaking beans for 12~24 hours by mixing 50~80wt% of beans with 20~50wt% of water, and crushing the soaked beans to extract soymilk; mixing 30~80wt% of soymilk with 20~70wt% of vegetable oil, to form the water repellent; and coating the environment-friendly water repellent to the surface of soil.
Abstract:
PURPOSE: A method f or preserving stone cultural sculpture is provided to improve physiochemical and mechanical properties using acrylic monomer. CONSTITUTION: A method for preserving stone cultural sculpture comprises: a step of drying the stone sculpture in a vacuum oven; a step of cooling by room temperature; a step of mixing 0.1-1 wt% of initiator to an autoclave; a step of adding dried stone sculpture to the autoclave and pressurizing at 1-30 atm for 10 to 15 hours; a step of sealing with a sealing material; and a step of polymerizing.
Abstract:
PURPOSE: A corrosion protection composition for stabilization of bronze cultural properties and a treatment method using the same are provided to improve the corrosion prevention of bronze cultural properties by dipping the bronze cultural properties in the corrosion protection composition contained in a stabilization bath of 25~45 °C. CONSTITUTION: A corrosion protection composition for stabilization of bronze cultural properties comprises alcohol, benzotriazole 3~7 weight%, and a mixture of iodinated kalium or iodinated silver or iodinated kalium and iodinated silver 0.01~2 weight%, wherein alcohol includes 1~5 carbons. The temperature of a stabilization bath with the corrosion protection composition is 25~45 °C. The dipping time in the stabilization is 24~72 hours.
Abstract:
PURPOSE: A pigment composition for DANCHONG(the edge of the eaves) capable of maintaining a distinctive green color emitting high-intensity green fluorescent light as characteristics of conventional pigment (EMERALD GREEN) used in painting works for pattern painting and excellent in durability, light resistance and environmental pollution resistance is provided which does not contain toxic components and is useful as a substitute for conventional pigments. CONSTITUTION: A pigment composition, which has been traditionally used in Korea for painting a wall of a house or a temple comprises 38 to 43% by weight of titanium dioxide, 20 to 25% by weight of chalk, 11 to 19% by weight of permanent yellow, 12 to 20% by weight of cyanine green and 5 to 7% by weight of chrome yellow. The pigment composition has distinctive green color emitting high-intensity green fluorescent light, does not contain toxic components different from conventional pigments containing copper and arsenic as a main component and is environmentally favorable.
