Pulp molding is a three-dimensional papermaking technique. It uses waste paper as a raw material and molds a certain shape of paper products on a molding machine.
It has four advantages: the raw material is waste paper, including board paper, waste paper box paper, waste paper, etc., with a wide range of sources; its production process is completed by processes such as pulping, adsorption molding, drying, and shaping, and is harmless to the environment; It can be recycled and recycled; its volume is smaller than that of foamed plastic, it can be overlapped, and transportation is convenient.
Pulp molding, in addition to meal boxes, tableware, more industrial buffer packaging, including egg boxes, egg trays, fruit trays, flower pots, disposable medical potty, etc., is currently developing very rapidly.
Pulp molded products are a new type of packaging material that has been rapidly developed in recent years and are an excellent alternative to wood.
Pulp molded products use raw material beating - ingredients - molding - drying - stereotyped manufacturing process. Since a large amount of water (about 55-60%) remains on the workpiece after molding, the moisture content of the final product is 12-14%. Therefore, the moisture that accounts for the weight of the workpiece is removed during the drying process of the workpiece. This part of the water all depends on absorbing heat and turning it into steam. Due to the phase change in the drying process, the energy consumption is very high. Pulp molded products are processed into high energy consumption products. For this reason, thermal analysis of the energy conversion process of its drying is very necessary. Because the analysis can improve the design and processing of drying equipment and improve the utilization of energy, it has important guiding significance for reducing the production cost of pulp molded products industry.
In recent years, with the increasing emphasis on national agriculture, medical products, food packaging, industrial packaging linings, and building materials, the development of agriculture has also received much attention. Therefore, the road to sustainable agriculture is also the country’s first annual document. Claim. Seedlings of flower seedlings are also an important part of agricultural development. Originally, plastic pots or black plastic films were used as seedlings for planting seedlings. However, such products cannot be degraded. If they cannot be cleaned up in time, it will cause land pollution, so people It is also looking for a new alternative product, and the pulp molding is derived from the natural features as the best alternative!
The development and application of pulp molding products have become an inevitable trend in social development. Such products will also play a crucial role in the development of all sectors of society, relying on their social, economical, artistic and non-polluting nature. Such advantages as simple technology will surely play a role in protecting the natural environment and improving the living environment. At the same time as a commodity, it has a very broad market space and development prospects and will contribute to the promotion of economic development.
