3 The main problems with current bamboo plywood templates
3 1 Product quality issues
At present, the main quality problems of bamboo sheet metal stencil products are uneven thickness, large surface chromatic aberration, depression or pitting on the surface, and different degrees of opening defects. The service life is also short. Generally, the turnover is 10 to 20 times. If the management is not used strictly, the difference is larger than that of the foreign wood plywood template. For example, the Simpson's wood plywood template specifies the single-sided medium density. The cladding template can be used 10 to 25 times, the single-sided high-density cladding template can be used 25 to 50 times, the system molding operation can be used hundreds of times, the double-sided high-density cladding template can be used 30 to 50 times, system molding The job can be used 200 times.
The main reasons for the decline in product quality: 1 fierce market competition, some manufacturers in order to seize the market, the use of cutting corners and other methods, ignoring product quality, low-cost competition; 2 blindly expand production, a few manufacturers regardless of market capacity, a large number of plants or increase Production line, ignoring product quality management; 3 original benefits, no large technology and equipment investment, most of the factory's technical strength is weak, do not pay attention to attract talent, lack of new technology development, quality testing methods behind.
3 2 Construction application problems
The bamboo glue board formwork is a new type of building material. The production plant and the construction enterprise don't know much about its construction application characteristics. In the product introduction of the manufacturer, there is almost no guidance on the construction content. How should the construction enterprise correctly use the bamboo glue board? The formwork is also unclear, resulting in frequent quality accidents in which the poured concrete is severely deformed, as well as quality disputes between the construction company and the production plant. For example, in the application of bamboo slab formwork, the static bending strength and elastic modulus will decrease to varying degrees due to the increase of water absorption rate, number of times of use or load time. Generally, construction companies do not understand this, so the support design is unreasonable. And cause a quality accident. In addition, in order to reduce the construction cost, many construction companies purchase low-priced inferior bamboo slab formwork. The static bending strength and elastic modulus of the stencil itself are very low. After water absorption during construction, the static bending strength and elastic modulus decrease. More, it is more prone to quality accidents.
3 3 Market Management Issues
In recent years, with the large-scale promotion and application of bamboo glue board formwork, many bamboo glue board factories have been built and expanded in various places. Due to the chaotic construction market, the lack of open, fair and fair trading environment and strict quality supervision measures have led to product quality. decline.
4 suggestions
4 1 Strengthen the quality supervision and management of bamboo glue board factory
The reasons for the poor quality of current products are mainly market confusion, lack of quality supervision and management measures. To this end, it is recommended that the relevant departments authorize relevant personnel to conduct product quality supervision and quality certification on a regular basis. For manufacturers with poor product quality, low technical level and no production conditions, they should promptly expose and warn, and if necessary, order the production to be rectified. For manufacturers with strong technical strength and good product quality, quality certificates should be issued and their products should be recommended to users. The construction company is required to use the products of the quality certificate manufacturer.
4 2 Actively develop high-grade bamboo glue board templates and other bamboo products
Some powerful bamboo glue board manufacturers should improve their production equipment and production processes through technological advancement, improve product quality, and improve the construction characteristics of bamboo glue board formwork. At the same time, it is necessary to increase technical input and actively develop high-grade bamboo glue board formwork to meet the requirements of construction projects.
In addition, the current annual production capacity of bamboo glue board factory has far exceeded the market demand. Therefore, some manufacturers with technical strength should develop other products as soon as possible. For example, the development of various bamboo flooring, architectural decorative panels, mobile homes, work sheds, etc., is also a promising product.
4 3 Give full play to the self-discipline of industry associations
According to the spirit of the document “Several Opinions on Accelerating the Cultivation and Development of the Association of Industry and Commerce†by the State Economic and Trade Commission, the China Formwork Association held the “National Bamboo Rubber Board Workshop†in May 2000 and drafted “Bamboo Glueâ€. The self-discipline convention for board member companies, which regulates industry prices, safeguards the overall interests of the industry, strengthens quality management, and resists blind price reduction.
