Description
Technical field
The present invention relates to the manufacture method technical field on floor, particularly relate to a kind of manufacture method using discarded leftover pieces to produce solid wooden floor board。
Background technology
Solid wooden floor board is with natural material timber for raw material, the floor processed。Owing to selecting natural material, remain its natural true qualities, will not produce to pollute, not easily dust suction, just catering to consumers in general and pursuing health, advocating natural style, be genuine green building productions, solid wooden floor board has comfortable foot feeling, good springiness, coefficient of friction advantage little, anti-skidding, long-lived simultaneously, has won the favor of consumers in general on house ornamentation market。
But solid wooden floor board adopts expensive, and employing log is raw material, and the consumption of resource is very big。The simultaneously leftover pieces of some timber on market, also have some agricultural wastes to take the mode burned to process as millet straw, rice chaff, straw the like waste, severe contamination air and environment, and people's lives are created strong influence。
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of manufacture method using the waste agronomic crops such as wood leftover material, millet straw, straw to produce solid wooden floor board, to reach resource reusable edible, reduces the effect of cost。
The invention provides the manufacture method of a kind of solid wooden floor board using discarded leftover pieces to produce, comprise the following steps:
Discarded leftover pieces → discongest → dry → impregnation → redrying → assembly → High frequency heating gluing plate → select plate → spray limit → sanding → back of the body of recombinating → cut out is coated with → solidifies → rolls priming paint → photocuring → sanding → roll again priming paint → photocuring → sanding → dedusting → roll color → pouring finish paint → levelling → solidification of heating → drench finish paint limit again and be coated with → heat levelling → solidification (circulating repetition n times) → finished product → select plate packing → finished product → warehouse-in
Described leftover pieces can be the leftover pieces of waste wood, it is also possible to is the mixture of waste wood leftover pieces and the arbitrary proportion of the agricultural wastes such as millet straw, straw。
Discongest: by suiting and extruding the mode combined, leftover pieces are discongested out along machine direction crackle and crack；
Dry: the leftover pieces after discongesting to be dried, moisture content is down to less than 10%；
Impregnation: be immersed in glue by dried leftover pieces, makes to infiltrate through equably in leftover pieces lumen and crack glue；Described glue is phenol resin solution, and solid content is 20-30%
Redrying: the leftover pieces after impregnation are carried out redrying, says that moisture content is down to 10-15%；
Group embryo: by the leftover pieces after redrying at same direction, thickness is different with different levels organizes embryo on precompressed baling press, and weighs according to density set in advance, start after hydraulic system compresses and bind with plastic tape；
High-frequency heating gluing is recombinated: be placed between the seaming chuck of high frequency press and lower machine negative pole and each middle plate by the leftover pieces after group embryo, the side form relative movement of dual-side simultaneously, utilize paired skewback to move up and down the location realized side form after putting in place, by upper and lower and dual-side three direction pressuring methods, leftover pieces are pressurizeed and high-frequency heating gluing；The restructuring of high-frequency heating gluing is that two action of alternative electric field utilizing high frequency generator to produce are on leftover pieces, the dipole molecule making leftover pieces second is polarized in the electric field, produce dielectric loss and self-heating, making the inside and outside colleague's heating of leftover pieces, adhesive generation polycondensation reaction solidify；
Preferably, the HF current frequency of described high-frequency heating gluing restructuring is 7.5-8.6Mc；In this frequency, form resonant condition, keep maximum heating efficiency；
Preferably, described high-frequency heating gluing is many laminates, and including seaming chuck, lower bearing bracket negative pole pressing plate sum layer center platen, existing positive pole also has negative pole, forms 2-10 high-frequency electric field, and a heating cycle can produce 2-10 block restructuring group material。
This programme compared to conventional thermocompression molding scheme have the beneficial effect that 1, processing method that discarded leftover pieces are adopted timber to discongest by the present invention, the method remains discarded leftover pieces original major part characteristic on the one hand, meet again the needs of floor restructuring on the other hand, solve discarded leftover pieces material difference, the material defect that heart sapwood matter difference is big, timber theory utilization rate reaches 100%；2, conventional thermocompression method of forming equipment is simple, prepares target thickness and is generally less than 20mm, and the target thickness of preparing of Scrimber generally will at more than 200mm；The side form relative movement of design dual-side during the restructuring of 3, high-frequency heating gluing, utilize paired skewback to move up and down after putting in place and realize side form location, upper and lower and the pressuring method production simultaneously of three directions of dual-side discarded matter recombinant material cant section is wooden uniformly, and the loss of load limit is little；Use resonant frequency during the restructuring of 4, high-frequency heating gluing, keep maximum heating efficiency, improve energy utilization rate。
