Abstract: An adhesive includes an organic material, an inorganic material, a curing agent and a catalyst. The adhesive is able to bond the wood material, especially recycled wood material. The wood material is not necessary to have any pretreatment like removing color, pigment or plastic lining so as to be introduced to the film process directly. After breaking and adjusting the moisture content of the wood material, it can be mixed with the adhesive and hard pressed into wood product with good duration and quality. The adhesive and the production method of wood board is able to ameliorate the problem of the conventional water based adhesive to save energy and processing time.

Abstract: Present invention is related to an adhesive, a production method of a wood board using the adhesive and product thereof. The adhesive of the disclosure comprises an organic material, an inorganic material, a curing agent and a catalyst. The said adhesive is able to bond the wood material, especially recycled wood material perfectly. The wood material is not necessary to have any pretreatment like removing color, pigment or plastic lining so as to be introduced to the film process directly. After breaking and adjusting the moisture content of the wood material, it can be mixed with the adhesive of the present invention and hard pressed into wood product with good duration and quality. The adhesive and the production method of wood board provided by the present invention is able to ameliorate the problem of the conventional water based adhesive to save energy and processing time.

Abstract: Composition for building materials comprises of fly ash from flue gas desulfurization. The fly ash (? CaSO4 anhydrite), obtained from circulating fluidized bed flue gas desulfurization, is mixed with binder reactants at a ratio of 9:1. It's mainly used for non-structural cement mortar, bricks for paving walkways, brick wall decors, fire-resistant walls for interior partitions, plasterboards and so on. The binder reactants compose of 70% CaSO4.½H2O, 10% Na2SO4, 10% CaO, 5% NaOH, 0˜5% cement and 0˜5% starch. When the binder reactants are mixed with fly ash and water (30% to 40% of the above total weight), the hydration process of CaSO4 anhydrite is accelerated.
