Distinction between "Pulp Molding" and "Plant Fiber Molding"

Source: DateTime:2016-01-19 Hits:232

"Pulp molding", also known as "plant fiber molding". For example, the industry standard «Molded pulp (plant fiber) disposable tableware production line» published on 2014-07-09 and implemented on 2014-11-01 writes pulp molding as: Pulp (plant fiber) molding. But in fact, the scope of "plant fiber molding" is wider than that of "pulp molding".

The Chinese word "plastic" in "molding" in "plant fiber molding" or "pulp molding" can easily be understood as the "plastic" of "plastic", and it is thought that it contains plastic components. The Chinese word "plastic" in "plant fiber molding" or "pulp molding" means "molding", and "molding" means using molds to "mold" various shapes of products. Because "plant fiber molding" or "pulp molding" has a heat-press setting process. Before 1992, it was also called: "Pulp press molding".

"Plant fiber molding" or "pulp molding" is to use renewable plant resources such as bamboo, wheat straw, reed, bagasse and other plant fibers to produce various fiber daily necessities, fiber paper mold tableware, fiber paper ,molded trays, fiber-paper-molded industrial products, shock-proof mats, packaging trays, non-planar fiber-paper-molded decorative wall panels, and non-planar fiber-paper-molded three-dimensional products through mold molding.

Due to the molding technology and the need for waterproofing. The "plant fiber" is mainly plant fiber such as pulp made by cooking, so "plant fiber molding" is usually also called "pulp molding".

Pulp molding is a process in which the fibers in the slurry are made into a wet blank using a suction filter forming mold, and then the wet blank is transferred to a hot pressing mold for pressure drying and shaping, and then sent out of the hot pressing mold.

Common concepts of pulp molding:

1. Pulp, a mixture of plant fiber and water.

2. Wet semifinished product, when the water in the slurry is pumped out, the fibers in the slurry are adsorbed to form a blank with the same shape as or close to the shape of the product.

3. Pulp molding, A process of using a suction filter mold to make the fibers in the slurry into a wet green, and then dry and shape it.

4. Suck-filter forming molds, used to make molds for wet billets.

5. Suck-filter forming, the process of suck-filter forming molds to absorb plant fibers to make wet blanks.

6. Heating mold, through pressurization and heating, the wet blank is made into a mold for dry products.

7. Hot press mold solidifing, a process in which the wet body is pressurized and heated through a hot press mold to turn the wet body into a dry product.
