Abstract
The invention discloses a kind of method for demoulding of artificial wheat-straw board, this method uses polyfluortetraethylene plate or poly tetrafluoroethylene or polytetrafluoroethylene (PTFE) net for demoulding material, it is fixed on backing plate and heating platen, or the upper and lower surface of wheat straw slab is placed directly within, wheat straw slab and backing plate are separated so as to demoulding.The inventive method has the advantages that demoulding cost is low, technological operation is easy and good quality of product.
Description
Technical field
The present invention relates to a kind of production technology of artificial wheat-straw board, the specifically method for demoulding in artificial wheat-straw board production process.
Background technology
It is an emerging technology using agricultural wastes wheat straw production artificial wheat-straw board, it had both solved the process problem of agricultural wastes, and environment was not polluted, and is the environmental protection industry of a sustainable development, has formed large-scale production at present.
The content of the invention
The production technology of general artificial wheat-straw board is：Wheat straw material-particle preparation-screening-drying-screening-is glued-mated formation-hot pressing-saw side-inspection.Glue-applying technique needs to use PIC for adhesive, this kind of adhesive has excellent glued characteristic, but detrimental effect is also brought in process of production, haftplatte phenomenon is produced such as in wheat straw board hot pressing, so that the demoulding cleaning work of backing plate and heating platen becomes abnormal difficult, being normally carried out for production have impact on.
The method for demoulding that production artificial wheat-straw board is used at present mainly has following several：1. application at present is more widely the method that remover is sprayed in backing plate or wheat straw steel slab surface, and the advantage of this method is that cost is relatively low, but production operation is cumbersome；2. backing plate and wheat straw slab are isolated in wheat straw slab upper and lower surface brown paper, so as to play demoulding effect, the advantage of this method is to operate more convenient in technique, but cost is of a relatively high；3. sanding dusts are spilt in the upper and lower surface paving of wheat straw slab, backing plate and wheat straw slab is isolated, so as to play demoulding effect, the advantage of this method is with low cost, but dust precision of mating formation is difficult to ensure that, so as to influence the surface quality of production board；4. the urea-formaldehyde glue of not haftplatte is used to make adhesive in the upper and lower superficial layer of wheat straw slab, the wheat straw slab particle for applying PIC is separated with backing plate, so as to play demoulding effect, the advantage of this method is to be easier to implement in technique, but have the disadvantage to increase equipment investment, the oeverall quality of production board is not as the complete sheet material for applying PIC.
It is an object of the invention to provide a kind of demoulding cost is low, technological operation is easy and good quality of product artificial wheat-straw board production technology in method for demoulding.
The present invention is on the basis of above-mentioned method for demoulding advantage and disadvantage are summarized, by the Analysis and summary of lot of experimental data, it is proposed that a kind of method for demoulding of new artificial wheat-straw board：This method uses polyfluortetraethylene plate or poly tetrafluoroethylene or polytetrafluoroethylene (PTFE) net for demoulding material, is fixed on backing plate and heating platen, or is placed directly within the upper and lower surface of wheat straw slab, and wheat straw slab and backing plate are separated, so as to play demoulding effect.
Due to present invention employs the method for demoulding of new artificial wheat-straw board, reducing production cost, and it is easy to be operated on a production line, preferably realizes the industrialized production of artificial wheat-straw board, and make artificial wheat-straw board plate face smooth, it is easy to secondary operation.
Embodiment 1：
Before the heat pressing process of artificial wheat-straw board is carried out, polyfluortetraethylene plate is fixed on backing plate and heating platen, wheat straw slab and backing plate are separated, so that can easily demoulding after hot pressing.
Embodiment 2：
Before the heat pressing process of artificial wheat-straw board is carried out, polyfluortetraethylene plate is placed directly within to the upper and lower surface of wheat straw slab, wheat straw slab and backing plate are separated, so that can easily demoulding after hot pressing.
Embodiment 3：
Before the heat pressing process of artificial wheat-straw board is carried out, poly tetrafluoroethylene is fixed on backing plate and heating platen, wheat straw slab and backing plate are separated, so that can easily demoulding after hot pressing.
Embodiment 4：
Before the heat pressing process of artificial wheat-straw board is carried out, poly tetrafluoroethylene is placed directly within to the upper and lower surface of wheat straw slab, wheat straw slab and backing plate are separated, so that can easily demoulding after hot pressing.
Embodiment 5：
Before the heat pressing process of artificial wheat-straw board is carried out, polytetrafluoroethylene (PTFE) net is fixed on backing plate and heating platen, wheat straw slab and backing plate are separated, so that can easily demoulding after hot pressing.
Embodiment 6：
Before the heat pressing process of artificial wheat-straw board is carried out, polytetrafluoroethylene (PTFE) net is placed directly within to the upper and lower surface of wheat straw slab, wheat straw slab and backing plate are separated, so that can easily demoulding after hot pressing.
