PP Hollow board solution

1, strengthen the hollow board product quality inspection at present, hollow plate production enterprises with perfect testing equipment is not much. Most have not passed the strict factory inspection. Even for the thickness tolerance test, it is not according to the provisions of the test method, and some even subjective judgment by the eyes of the thickness of classification. In the hollow plate production enterprises more concentrated areas can be set up a regional test center, to provide convenience for each plant.
2, the establishment of quality control and supervision mechanism of the hollow plate should be as other building materials as the implementation of the permit system, in order to fundamentally put an end to the poor quality of products into the market.
3, improve the turnover of the hollow plate template is not a problem in technology. Now the product is not up to this requirement, the key is to randomly change the plastic, change the hot pressing parameters, not in accordance with the correct process conditions. Some factory production technology has not been introduced through the formal channels, the production of technical personnel have not been rigorous training. The plant shall be strictly in accordance with the best production process of hollow plate.
4, to solve the hollow board thickness tolerance of each respective factory strictly pair of bamboo, bamboo mat detection and classification, try to to is the same as the thickness of bamboo strand; (2) in does not affect the strength of the premise, in which sandwiching a piece to a number of compressed relatively large wood veneer, in order to reduce the thickness tolerance of bamboo; 3, hollow board of secondary processing, the first extruded hollow plate sand light to thickness and then covered with plastic film; (4) in the bamboo curtain, bamboo processing sectors use mechanical processing controlling the thickness of, the production plant in bamboo production areas set up base in the processing of raw materials, support bamboo farmers gradually the use of mechanical processing.
5, the surface quality of the solution to the needs of the user needs to produce various grades of hollow plate template. If in the surface layer of the hollow plate put a layer of wood veneer panel can basically eliminate bamboo stria marks, but to minimize the use of melamine resin coated to increase the wear resistance and surface hardness, complete and smooth. For steel frame hollow slab formwork panel should be modified melamine resin or alcohol soluble phenolic resin impregnated paper coated, impregnated paper of Zhang number visible on the surface roughness and flatness of requirements.
