Classification of plant fiber pulp products and analysis of advantages and disadvantages of disposable biodegradable pulp moldin

First, ordinary pulp products, as the name suggests, are molded products made of yellow pulp, newspaper pulp, A4 paper pulp, etc. It has low hygiene requirements and low price.

Second, sugarcane pulp products are molding products made of biological pulp, wet pulp or pulp board after shredding and molding again. Sugarcane fiber is medium-length fiber, with the advantages of moderate strength and moderate toughness, is currently the most suitable raw material for molding products, so sugarcane pulp products are currently the most widely used.

Wheat straw pulp products, divided into machine mold fiber wheat straw pulp molding products, chemical wheat straw pulp molding products and chemical wheat straw pulp molding products, wheat straw pulp fiber short, good stiffness, brittle products, poor flexibility, general production process requires long fiber neutralization, increase its toughness.

Fourth, bamboo pulp products, belong to the medium and long fibers, performance between coniferous wood and broadleaf wood. Bamboo pulp production products toughness, smooth and delicate surface, but easy to appear fluffy fluffy fiber, you can add the number of complex shape, small slope, R angle small products.

5. Wood pulp products are mainly divided into coniferous wood pulp and broadleaf wood eco cutlery pulp. Coniferous wood pulp fiber is long and fine, pure wood pulp, less impurities. Broadleaf wood pulp has thick and short fibers, many impurities, relatively low finished strength, loose finished products, strong absorption, and high opacity. Paper made from coniferous wood pulp has good flexibility, folding resistance and tensile strength. Paper made of broadleaf wood pulp has high thickness, high stiffness and good packaging performance. So the thickness and density of products produced from different wood pulp will vary.

The intransitive verb reed pulp products are mainly used for paper making, and molded products are mostly used for low-grade products. Reed pulp is not easy to remove reed nodes during production, has many impurities and low whiteness, but has low price and good water filtration. Due to the fluffy fiber, the finished product is thick and takes up a lot of space.

Seven, palm pulp products, is a product made from palm fruit and palm leaves extracted fiber, rarely used, mainly because of the high oil content of palm, not easy to remove, but good stiffness.

Eight, melon vine pulp products, melon vine pulp generally refers to the yellow flower vine, loofah vine and other melon plants can be used to produce molding products, but different kinds of fibers vary greatly. Most of these fibers are short fibers, poor stiffness, impurities are difficult to deal with, and therefore not widely used.

Nine, cotton rod pulp products, using only cotton rod, after removing the surface table, with cotton rod intermediate tissue production and processing of products, cotton rod fiber molding products fiber fluffy, poor stiffness, mostly used in low-grade paper.

Machine grinding fiber products, the use of grinding methods, so that plant fiber raw materials in the role of mechanical force dispersed into fibers, with this method of production of pulp called mechanical pulp. Mold fiber is not free from lignin and cellulose, poor fiber bonding, the need to use chemical pulp or chemical pulp, mold fiber additions should not exceed 50%, more than 50% of the product is more likely to debris.

Eleven, chemical machine pulp products. Chemical mechanical pulp is a certain chemical treatment before grinding pulp, the pulp obtained is called chemical mechanical pulp. Chemical mechanical pulp generally contains higher lignin and cellulose content, lower hemicellulose content to obtain a higher pulp rate. This pulp is mostly used for mid-range molding products, and its cost is higher than mechanical pulp and lower than chemical pulp, and its bleaching, hydration and water filtration properties are close to those of mechanical pulp.

Chemical pulp products. Mainly processed after acid and alkali treatment of molded products. These products are fine and smooth, with more wood content retained in the pulp.
