When the foaming device foaming foam is a certain temperature limit . Too high or too low are inappropriate in a standard temperature . Material temperature to 20 ℃ to 24 ℃ at best, will be expanded too quickly , drawing a short time, gel time is short, small foam material viscosity , good fluidity , mixing, easily lead to poor local exhaust bubbles layered material shortage and excess material so uneven density distribution box ; are low foaming and long time , drawing a long time , the big foam material viscosity , poor mobility , can cause uneven mix , local will lack of material , there are crispy layered foam box . Ambient temperature greater than or equal to 20 degrees Celsius, a small foam material viscosity is too high , liquidity is good, while likely to cause overflow caused by foam fast , easy to produce material shortage ; . Too low viscosity, poor mobility, poor mixing simultaneously. slow foam , causing contraction box or boxes layered foam , such layered back or side , the housing can also cause partial lack of material , mold temperature should be too readily in the 35 ℃ to 50 ℃ resulting foam material in cabinets good fluidity , but at the same time will cause the interior parts of the foam material in close proximity to the fast reaction , the gas produced and layered or multi- material shortage due to high mold temperature , making the cabinet liner easily deformed ; low temperature, the reaction is slow, foam material to produce crispy shell and layered close . The main good grasp of foam material temperature , ambient temperature , and the temperature of the mold , you can probably grasp the overall temperature foaming .
