What types of pulp molding additives?
- Aug 11, 2012 -

Pulp products from the expected to forming, of which the main ingredient or pulp. However, to complete the entire process, auxiliary materials (auxiliaries) as auxiliary materials are also indispensable. The following for your brief introduction to the production of pulp molding additives related to the use of.
Introduction of pulp molding additives
1, waterproofing agent. The main ingredients are paraffin, rosin gum, chromium chloride stearate, silicones, chitosan and so on. The main role is to improve the quality of the pulp after curing the model product, and reduce the surface tension, fill the product within the gap, which play a waterproof effect.
2, anti-oil agent. Multi-purpose fluorine-containing surfactants, that is, hydrogen atoms in the hydrocarbon chain partially or totally substituted by fluorine atoms, which are formed by fluorocarbon chain or oxygen-containing fluorocarbon chain activators, have high surface activity because of their high surface activity Stability and high chemical inertness, which play a waterproof, anti-oil and so on.
3, enhancer. That is, the strength of pulp products to enhance aids referred to. By adding this strength agent, the finished pulp molding plastic products will be at least 2 to 3 times higher than the non-added strength, such as compression, tensile strength, bending resistance, durability and so will be improved.
Generally speaking, the production process that can improve the product quality and can be used within the minimum cost is the best, and the practical application of the additive for pulp molding products shows the improvement of product quality. The rational allocation of production resources and Use to create high value products.
