Embodiment 1
[0011] A processing method for blackening bamboo, comprising the following steps:
[0012] (1) Raw material preparation: crush bamboo and bamboo processing residues into bamboo powder below 10 mesh, according to the mass ratio m 竹粉 :m 黑化剂 =100:0.1, bamboo powder and blackening agent are evenly mixed to obtain bamboo powder raw material; wherein the moisture content of bamboo powder is 55%; blackening agent is composed of iron molybdate, zinc borate, ammonium polyphosphate, titanium dioxide by mass ratio m 钼酸铁 :m 硼酸锌 :m 聚磷酸铵 :m 二氧化钛 =1:1.5:2:6 mixed;
[0013] (2) Blackening forming: the bamboo powder raw material is evenly spread into the stainless steel mold, and then the temperature and pressure are raised. When the temperature rises to 180°C and the pressure rises to 3MPa, the pressure is kept for 70 minutes, and then the pressure is maintained, and the heating is stopped. , slowly cool to room temperature, and release the pressure to obtain the blackened bamboo board;...
Embodiment 2
[0015] A processing method for blackening bamboo, comprising the following steps:
[0016] (1) Raw material preparation: crush bamboo and bamboo processing residues into bamboo powder below 10 mesh, according to the mass ratio m 竹粉 :m 黑化剂 =100:0.2, bamboo powder and blackening agent are evenly mixed to obtain bamboo powder raw material; wherein the moisture content of bamboo powder is 60%; blackening agent is composed of iron molybdate, zinc borate, ammonium polyphosphate, titanium dioxide by mass ratio m 钼酸铁 :m 硼酸锌 :m 聚磷酸铵 :m 二氧化钛 =2.0:1.0:4:5 mixed;
[0017] (2) Blackening molding: The bamboo powder raw material is evenly spread into the stainless steel mold, and then the temperature and pressure are raised. When the temperature rises to 190°C and the pressure rises to 4MPa, keep the pressure for 50 minutes, then keep the pressure and stop heating , slowly cool to room temperature, and release the pressure to obtain the blackened bamboo board; wherein during paving, th...
Embodiment 3
[0019] A processing method for blackening bamboo, comprising the following steps:
[0020] (1) Raw material preparation: crush bamboo and bamboo processing residues into bamboo powder below 10 mesh, according to the mass ratio m 竹粉 :m 黑化剂 =100:0.3, bamboo powder and blackening agent are evenly mixed to obtain bamboo powder raw material; wherein the moisture content of bamboo powder is 65%; blackening agent is composed of iron molybdate, zinc borate, ammonium polyphosphate, titanium dioxide by mass ratio m 钼酸铁 :m 硼酸锌 :m 聚磷酸铵 :m 二氧化钛 =2.5:0.5:5.0:5.5 mixed;
[0021] (2) Blackening molding: the bamboo powder raw material is evenly spread into the stainless steel mold, and then the temperature and pressure are raised. When the temperature rises to 200 and the pressure rises to 4MPa, the pressure is kept for 40 minutes, and then the pressure is maintained, and the heating is stopped. Slowly cool to room temperature and remove the pressure to obtain the blackened bamboo board;...
