How to do the corn stalks
Process Technology Line:
1. Straw density plate:
Air dry straw → impurity removal → cut off → wind selection (blown out of the heart) → cans → high pressure steam → spray → fine → spray → drying → pavement → preload → hot pressing → edge → cutting → packaging → finished product
2. Straw crushed plate (particleboard)
Drying Straw → Cutting → Wind Selection → Recovering → Drying → Screening → (Surface Layer, Dust, Core Material) → Mixing → Pavement → Preloading → Hot Press → Edge → Cutting → Inspection → Packaging
3. Straw composite board
Straw → Cutting → Steam Blasting → Mixing → Paving → Wood Veneer → Glue → Preloading, Hot Press → Side → Varnish → Sanding → Finished
4. New wall materials:
Corn stover high grain straw → election → leaves → cut → pavement → irrigation → do the surface layer → veneer → sanding → finished
In addition to the above processing, the straw can also be used for pulp making after steam blasting, which is about a third less expensive than traditional pulping methods and only one third of the traditional method. It is helpful to solve the problem of pulp gap caused by the forced cessation of small papermaking by the state.
Fourth, the main technical key and expected to achieve the technical and economic indicators:
1. Main technical key:
① developed as low as possible, environmentally friendly, waterproof superior, infiltration of a good name of the glue.
② design and improvement of grading pavement.
③ steam blasting equipment selection and the determination of the main process parameters.
④ hot pressing and cold pressing process parameters adjustment.
2. Expected technical and economic indicators:
① adhesive; solid content: 60% -65%
??????????Free formaldehyde content: 0.2% or less
??????????Viscosity: coated with 4 cups: 30 ℃ 10-20 seconds (fiberboard)
?????????????????????????????????50-65 seconds (particle board)
