Description
Technical field
The utility model relates to a kind of container bottom board, especially relates to a kind of composite container baseboard.
Background technology
Bamboo wood is wide, wide in variety in China place of production, aboundresources, and the growth of bamboo is fast, with short production cycle, thereby its price is cheap than timber, and bamboo wood has good intensity and toughness, the bamboo wood composite container baseboard that wood substituted by bamboo is produced, both save timber, improved again the performance of container bottom board, become gradually the main product of container bottom board.
But, in the production of existing bamboo wood composite container baseboard, for the speed production process, improve the utilization ratio efficient of hot press, base plate semi-finished product after the hot pressing are all taked the high temperature ejecting plate, in the half-finished temperature of base plate during still up to 80 ℃-90 ℃, just operate hot press and carry out high temperature release ejecting plate, make base plate semi-finished product dilatancy under environment under low pressure of high temperature, then for making it recover due size, re-use another hot press it is carried out the secondary pressurized cooling, like this, not only increased operational sequence, increase the weight of staff's workload, what is more important is in the process of aforesaid high temperature release ejecting plate and secondary pressurized cooling, the half-finished bonding quality of base plate is carried out destruction twice, greatly affected the strength character of base plate.
Secondly, in the manufacture process of existing bamboo wood composite container baseboard, always with the method for tape-stripping carry out veneer sticking patch, squeegee, its used adhesive tape is deposited in the base plate, when base plate work is stressed, cause base plate interior the tearing of adhesive tape place, reduced the bonding strength of base plate.
At last, there is again the defective that is easy to buckling deformation in higher, the lower-cost bamboo wood composite container baseboard of the relative consumption of bamboo wood, and reduction cost and raising quality can not be taken into account simultaneously; In addition, the clone's veneer panel that uses for reaching the desired clone's grain of wood in container bottom board surface has increased again production cost.
So existing bamboo wood composite container baseboard still exists the lumber consumption cost higher, the defective that production process is complicated, efficient is low, capability and performance is low.
