Abstract
The invention relates to a process for manufacturing an aspen container floor, which specifically comprises the steps of: 1, selecting a short core veneer, then coating adhesive on two surfaces of the short core veneer and performing oriented paving, externally covering the short core veneer with 2 to 5 layers of cross-band veneers with the same specification, hot-pressing for 15 to 25 minutes under the pressure from 15 to 20MPa, and calibrating thickness and polishing to obtain a core plywood serving as the inner layer material of the container floor; and 2, selecting 1 layer of top-quality veneer and 2 to 3 layers of long veneers, coating the adhesive on the top-quality veneer and the long veneers and performing parallel paving, hot-pressing for 10 to 15 minutes under the pressure from 25 to 30MPa, and calibrating thickness and polishing to obtain a high-intensity sheet serving as the outer layer material of the container floor. The process of the invention improves the utilization rate of raw materials, lowers the product cost, enhances the anti-aging property of the product, shortens the period for hot pressing and raises the production efficiency.
Description
Technical field
The present invention relates to a kind of manufacture craft of poplar container bottom board.
Background technology
China is container production big country, produces more than 200 ten thousand standard containers of case amount per year, accounts for the world and produces more than 80% of case amount per year, needs the about ten thousand stere more than 100 of container bottom board every year.The producer of domestic production container bottom board mainly uses clone and raw material such as Tang Mu, eucalyptus and pine tree at present, mainly relies on import, and production cost is higher.Nanjing Forestry University's patented technology " bamboo wood composite container baseboard " is implemented on Anhui and Yunnan and other places, and about 2 ten thousand steres of yearly productive capacity, this product mainly utilize domestic product mao bamboon, pinus khasys, masson pine or larch etc. as raw material.Because the working (machining) efficiency of mao bamboon is lower, and unsuitable remote transportation, make that the bamboo wood composite container baseboard production scale is difficult to enlarge.
Summary of the invention
In order to overcome the deficiency in the background technology, the invention discloses a kind of technology of utilizing poplar to make container bottom board, purpose is to produce a kind of high strength and the good container bottom board of insect protected property through advanced person's production technology and chemical treatment measure.
Technical solution of the present invention:
A kind of manufacture craft of poplar container bottom board, concrete processing step is:
1, choose short central layer double spread stick orienting spreading, cover in 2～5 layers of length with short central layer same size plate hot pressing 15～25 minutes under the pressure of 15～20MPa outward, sandwich glued board is processed in fixed thick sanding, as the inner layer material of container bottom board;
2, choose and parallelly behind 1 layer of high-quality veneer and 2～3 layers long veneer coating adhesives mat formation, hot pressing is 10～15 minutes under the pressure of 25～30MPa, and the high strength thin plate is processed in fixed thick sanding, as the cladding material of container bottom board;
3, will be as the sandwich glued board double spread stick of endothecium structure; To simultaneously apply thermosetting resin as the high strength thin plate of the cladding material of container bottom board, under the pressure of 10～15MPa, a sandwich glued board and the hot-press gluing of two high strength thin plates processed the container bottom board blanket;
4, the container bottom board blanket is carried out the edging sanding again and handle, cut out according to customer demand then and be sawn into certain specification, after the assay was approved warehouse-in.
Said adhesive is the resistance to water synvaren; Be that the willow dust that will produce in this technology is after further pulverizing; Do the combination phenol that solvent makes its dissolving and formation have reactivity through catalytic reaction with phenol, and then generate synvaren with formolite reaction.
Add insect-proof agent in the said adhesive.
Said insect-proof agent is earlier with cypermethrin emulsification, adds protective agent then and bleeding agent is mixed and made into.
Beneficial effect of the present invention: the present invention has improved raw-material utilization rate, has reduced the cost of product; Improve the ageing-resistant performance of product, and shortened pressing cycle, improved production efficiency.
