Abstract
The formaldehyde purification and anti-cracking ecological board has the function of anti-cracking and removing formaldehyde, which is improved on the basis of the production process of ordinary ecological boards. Its key processes are different from the ordinary ecological board including the secondary adhesive mixing, secondary adhesive dipping, resin-impregnated paper storage, optimization of balanced laminate (1.0mm hight density fibreboard, HDF), stickers, hot pressing and so on. In addition, the core technology parameters of formaldehyde purifying ecological board involves several aspects such as the glue preparation ratio, curing time, dipping amount, storage environment of the resin-impregnated paper, hot-pressing process of the balanced laminate layer and the resin-impregnated paper. The anti-cracking property of the formaldehyde purification and anti-cracking ecological board under this process is greater than grade 4. The main active ingredient of formaldehyde purification and anti-cracking eco-board are chitin and nano-silicon, etc. The negative electric field generated by nano-crystalline silicon wafers adsorbs gas molecules such as formaldehyde, the active amino groups in chitin decompose these substances into water molecules, and the nano-silicon wafers also function as bactericidal agents to achieve the effect of air purification. After testing, the purification efficiency of formaldehyde purifying and anti-cracking ecological board ≥ 75%, and the formaldehyde purifying effect lasting ≥ 60%. In the intuitive formaldehyde purification experiment, the formaldehyde level can be approximately decreased to 50% within 10min and reduced to 0.3mg/m3 after 1h in the newly prepared formaldehyde purification and anti-cracking ecological board samples.
