Abstract
The invention relates to a production method of avoiding heating platen adhesion in straw plate production, namely a method of paving screening fines without glue on a surface layer. Isocyanate glue is adopted in the straw plate production to glue crushed straw materials well. Isocyanate glue has good adhesiveness to most materials, and also results in the problem of easy adhesion between a plate blank and a heating platen during hot pressing. In order to solve the problem of platen adhesion during the hot pressing in the straw plate production, the method of paving the screening fines without the glue on upper and lower surface layers is adopted, and in a production process, the method well solves the problem of the platen adhesion during the hot pressing in the straw plate production.
Description
Technical field
The present invention relates to a kind of production method preventing stalk board from gluing heating platen in producing, i.e. do not mix stalk board top layer paving
Glue screening fines.
Background technology
The agri-fiber based panel production process such as compressed straw slab, wheat straw board is: agricultural crop straw particle and various adhesive, auxiliary
Agent etc. are admitted to spreading machine after being uniformly mixed；Particle mixture is mated formation thereunder by spreading machine uniformly, continuously
Uniform motion the belt of transporter, guipure or backing plate on, make particle mixture become the heavy slabs such as continuous print；Mat formation molding
The heavy slab that waits enter after hot press, press starts pressing plate, and upper lower platen carries out heating pressurization to slab, and preset pressure pressed by press
Curve compacting slab；Again through transporting equipment slab is sent into chiller carry out cooling down, edging, stacking.
Being unfavorable for the wax of gluing owing to Caulis et Folium Oryzae straw, Wheat straw contain, wettability is poor, gluing by traditional water solublity
Agent is can not they are glued together, uses isocyanate glue bonding agent crushed straw aggregate well gluing to be got up.Carbimide.
Ester gum has good cohesive to most of materials, also causes the problem of haftplatte when hot pressing, is the master during stalk board produces
Want a difficult problem.
Summary of the invention
The present invention relates to a kind of prevent stalk board from producing in slab glue the production method of heating platen, i.e. on stalk board top layer
Spreading not glue mixing screening fines, it effectively solves the problem of haftplatte during hot pressing in stalk board produces, and solves with using additive method
Time in stalk board produces in hot pressing, haftplatte is compared, and expense is low, reduces the production cost of manufacturing enterprise.
The fines of the not glue mixing mated formation in top layer is twice laid.Stalk board produce in, screening machine will pulverize after material
Screening was Fructus Anisi Stellati, core layer material, top layer material, crossed fines.Wherein cross Fructus Anisi Stellati the most broken after return to production line, core layer material, top layer material are straight
Connect use, cross fines and belong to waste material.The present invention utilize the garbage in original production cross fines mat formation at the slab bottom and
The superiors, when solving hot pressing, slab glues the problem of heating platen, is finally removed by its sand when sanding.
For realizing the present invention: we are when agri-fiber based panel is mated formation, first not glue mixing screening fines is layered on the bottom,
Then spread layer, sandwich layer and upper epidermis, the most not glue mixing screening fines is layered on upper epidermis, is thus formed such as Fig. 1
Agricultural crop straw structure of plate slab.Due to agricultural crop straw slab the top be all topmost that fines is screened in not glue mixing, from
So will not glue heating platen, and low cost, haftplatte problem when the most both having solved in stalk board produces in hot pressing, reduce life
Produce the production cost of enterprise.
Accompanying drawing explanation
Fig. 1 is heating platen structure of plate slab schematic diagram viscous in preventing stalk board from producing.
In figure, 1 not glue mixing screening fines；2 slab upper epidermis；3 slab sandwich layers；4 slab layer；5 are not
Glue mixing screening fines.
Detailed description of the invention
Fig. 1 show the present invention, a kind of prevent stalk board from producing in slab glue the production method of heating platen, i.e. at straw
Plate top layer spreads not glue mixing screening fines structure of plate slab schematic diagram, its point five-layer structure, and 1 is that fines is screened in not glue mixing, and 2 is on slab
Top layer, 3 is plate sandwich layer base, and 4 is slab layer, and 5 is that fines is screened in not glue mixing.It is viscous heat during one prevents stalk board from producing
The production method of pressing plate, the problem of haftplatte when effectively solving in stalk board produces in hot pressing.
The present invention is when agri-fiber based panel is mated formation, and first not glue mixing screening fines is layered on the bottom (5), then spreads
Mixed glue layer (4), mixed glue sandwich layer (3) and mixed glue upper epidermis (2), the most not glue mixing screening fines (1) was layered on
On upper epidermis, thus formed such as the agricultural crop straw structure of plate slab of Fig. 1.Due to agricultural crop straw slab the top with go up most
Face is all that not glue mixing screens fines, thus without viscous heating platen.
Claims (2)
1. one kind prevents slab in stalk board production from gluing the production method of heating platen--and top layer spreads not glue mixing screening fines.
The most according to claim 1, during stalk board produces, slab divides five-layer structure as shown in Figure (1) shows, and 1 layer is not glue mixing sieve
Selecting fines, 2 layers is slab upper epidermis, and 3 layers is slab sandwich layer, and 4 layers is slab layer, and 5 layers is that fines is screened in not glue mixing.
