How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: 1 subject content and scope of application this standard specifies the technical requirements, test methods, inspection rules, marks, packaging, storage, etc of bilge coating for engine room This standard is applicable to the coating system of the bilge of the main engine, auxiliary engine and pump cabin of the steel ship 2 reference standard gb1724 test method for film fineness gb1727 test method for general preparation of film gb1728 test method for drying time of film and putty gb1732 test method for impact resistance of film gb1734 test method for vapor oil resistance of film gb1763 test method for chemical reagent resistance of film gb1765 test method for film preparation of wet resistance, salt fog resistance and weather resistance (artificial acceleration) gb1771 test method for salt fog resistance of primer Gb3186 sampling of paint products gb5210 determination of paint adhesion Faraday method gb6750 determination of density of paints and varnishes gb8923 determination of corrosion grade and derusting grade of steel surface before painting gb9750 packaging mark of paint products gb10834 determination of salt water resistance of marine paint salt water and hot salt water immersion method 3 technical requirements 3.1 General requirements 3.1.1 engine room bilge coating It shall be able to construct and dry under normal environment and ensure safety conditions 3.1.2 under the temperature of 20 ~ 25 ℃, the application period of two-component coating shall be in accordance with the technical requirements of each product manufacturer 3.1.3 the bilge coating of the engine room shall be able to be evenly mixed in the original container manually or mechanically within at least one year from the date of manufacture 3.1.4 the bilge coating of engine room shall be compatible with common shop primer 3.1.5 the bilge coating of engine room shall be suitable for brush coating, roll coating and airless high-pressure spraying, and no sagging shall occur during the construction within the specified film thickness 3.1.6 when the bilge coating of engine room is naturally aged or damaged, it shall be able to repair with the original bilge coating system of engine room 3.1.7 the cabin bottom coating of engine room shall have good miscibility with the diluent specified 3.1.8 before painting the bilge coating of engine room, the steel surface must be completely derusted and degreased The derusting requirements are ST3 in gb8923 3.2 technical indicators the technical indicators of the bilge coating of the engine room shall meet the following requirements: A fineness (μ m): ≤ 80 (except for the scale coating);
