Abstract:
For promoting the special birch plywood applied on liquefied natural gas (LNG) ship to be made in China, the materials for LNG ship were studied with China birch and water solubility PF resin. The L9(33) experiments were based on three factors of pressure, temperature and time. The density, MOE, MOR and shearing strength were tested and the reasonable technology parameters were obtained: pressure 1.2 MPa, temperature 140℃ and time 1.0min/mm. Mechanical properties of the plywood in normal condition and after being treated by LNG were analyzed. The result showed that MOE, MOR and shearing strength reduced and the thickness swelling of plywood was 0.96%. Comparison between China birch plywood and Finland birch plywood showed that the birch plywood made by China birch under the reasonable technology parameters could instead of the Finland birch plywood using on LNG ship for the insulated tank.
