Abstract
A kind of respirable straw board manufacturing process, step is as follows：The stalk dried is fabricated to fiber, stalk fibre is placed in beater, added water, water accounts for 95% the 90% of stalk fibre and water inventory, and stalk fibre slurry is made in the mode ground using waterpower；The diatomite of at least 200 mesh is added into plant fiber pulp, stalk fibre is 70 ︰ 30 with diatomaceous mass ratio；Ground by mill or fluffer, stalk fibre and diatomite is uniformly merged；Wet embryo is made on sheet-forming machine；Wet embryo is toasted, the wet embryo after baking is transferred in mould, sizing is dried using sheet material forming machine, the dryness finalization time is set according to the thickness of sheet material, sheet material is reached that moisture content takes out less than or equal to naturally humidity in setting time.Have the advantages that simple production process, Product Green environmental protection, production cost are low by the product of the technique productions of the present invention.
Description
Technical field
The present invention relates to a kind of sheet processes, particularly a kind of respirable straw board manufacturing process is main
If manufacturing base material using stalk fibre and diatomite.
Background technology
At present, the various artificial boards that are packed for are to use the materials such as wood chip, wood-fibred, stalk mostly, and add adhesive
After extrude drying and moulding.These adhesives contain substantial amounts of formaldehyde, have very big harm to the health of people.Recent years,
Some enterprises, which produce, uses a kind of polyurethane binder（MDI）Produce artificial board, although without formaldehyde, but this adhesive
It is expensive, sheet material production cost is improved, is difficult to promote.
Diatomite has extremely strong physical absorption and ion exchangeable, with eliminate formaldehyde, regulation humidity, sterilizing,
Fire protection flame retarding, deodorization disappear taste, releasing negative oxygen ion, the function such as magnetic radiation of adsorbing television set, are referred to as respirable material.But
It is, diatomite is directly to use, it is necessary to add other materials that being formed after calcining just has application work(after diatom ooze
Can, and the diatomite for passing through calcining greatly reduces original various functions, and increase cost.
The content of the invention
It is an object of the invention to provide a kind of simple production process, any adhesive need not be added, and diatomite can be kept
Original function, the low respirable straw board manufacturing process of environmental protection, production cost overcomes the deficiencies in the prior art.
Respirable straw board manufacturing process of the present invention, step is as follows：
(1) the stalk dried, is fabricated to fiber；
(2), stalk fibre is placed in beater, added water, water accounts for the 95%-98% of stalk fibre and water inventory, is ground using waterpower
Stalk fibre slurry is made in the mode of mill；
(3), the diatomite of at least 200 mesh is added into plant fiber pulp, and stalk fibre is 70 ︰ 30 with diatomaceous mass ratio；Through
Mill or fluffer grinding are crossed, stalk fibre and diatomite is uniformly merged；
(4), the wet embryo that moisture content is 50%~60% is made on sheet-forming machine；
(5), wet embryo is toasted, the temperature control of baking is between 170 DEG C~190 DEG C, and the moisture content of wet embryo is 28 after baking
~35%；
(6), the wet embryo after baking is transferred in mould, mould during sizing, dryness finalization is dried using sheet material forming machine
Have temperature control between 170 DEG C~190 DEG C, operating pressure is 1.6 kilograms every square centimeter, drying is set according to the thickness of sheet material
Shaping time, makes sheet material reach that moisture content takes out less than or equal to naturally humidity in setting time.
Respirable straw board manufacturing process of the present invention, wherein described stalk fibre slurry is by disc mill or dredged
Solution machine is ground what is formed；Described baking temperature and dryness finalization temperature is 180 DEG C.
Wax coat is contained on respirable straw board manufacturing process of the present invention, stalk surface, and inside contains substantial amounts of two
Silica and pectin.Stalk fibre is diluted with water, and softens at a high temperature of certain, and the wax coat on surface comes off, what inside was contained
Silica and pectin discharge body surface, after the fusion together of these three materials, can possess bonding, moistureproof and waterproof, increase intensity
Characteristic.Because such a technique need not add adhesive, diatomaceous carrier is can be described as, and is not influenceed diatomaceous
Function.The compatible diatom ooze of the present invention and adhesive-free stalk mask-making technology, greatly reduce production cost, plentiful artificial
The function of sheet material, improves the competitive advantage in product market, is the environment-friendly products of novel ecological.Allow agricultural discarded object（Including
The various stalks such as corn, wheat, soybean, sorghum, paddy rice）Turn waste into wealth, peasant's crop straw burning can be alleviated and caused to environment
Pollution.The wood-based plate using timber as raw material is instead of, ecological environment is protected.As long as replaceable mould, such a technology can
To produce the product of different shape specification, the production of the product of 3D shapes can be also realized.To sum up, by technique productions of the invention
Product has the advantages that simple production process, Product Green environmental protection, production cost are low.
Embodiment
Respirable straw board manufacturing process of the present invention, processing step is as follows：

Stalk fibre slurry is made in the mode of mill, and grinding is ground by disc mill or fluffer；
(3), the diatomite of at least 200 mesh is added into plant fiber pulp, and stalk fibre is 70 ︰ 30 with diatomaceous mass ratio；Through
Mill or fluffer grinding are crossed, stalk fibre and diatomite is uniformly merged；
(4), the wet embryo that moisture content is 50% or 55% or 60% is made on sheet-forming machine；
(5), wet embryo is toasted, baking temperature control is 170 DEG C or 180 DEG C or 190 DEG C, and the moisture content of wet embryo is after baking
28% or 30% or 33% or 35%；
(6), the wet embryo after baking is transferred in mould, mould during sizing, dryness finalization is dried using sheet material forming machine
It is 170 DEG C or 180 DEG C or 190 DEG C to have temperature control, and operating pressure is 1.6 kilograms every square centimeter, is set according to the thickness of sheet material
The dryness finalization time, sheet material is set to reach that moisture content takes out less than or equal to naturally humidity in setting time.
