What are the types of additives for pulp moulding products?
Mar 21, 2018

Pulp products are expected to form from below, the main material is pulp. However, it is also necessary to complete the process as a supplementary additive for auxiliary materials (auxiliary additives). In order to give you a brief introduction to the production of pulp molded products auxiliary use related content.

Introduction to the types of pulp molded products.

1. Waterproof agent. The main ingredients are paraffin, rosin gum, chromium stearate, organic silicon, chitosan, etc. The main effect is to improve the quality of the pulp solidified into the model product, and reduce the surface tension, and fill the internal clearance of the product, thus making it waterproof.

2. Oil repellent. Multi-purpose containing fluorine surfactants, namely the hydrocarbon chain of some or all of the hydrogen atom replaced by fluorine atoms or oxygen after the formation of the fluorocarbon chain chain of fluorocarbon surfactant, because of its surface active agent with high surface activity, high heat stability and Gao Huaxue inertia, and waterproof, prevent oil, etc.

3. Reinforcer. That is, the paper pulp product strength enhancement auxiliary abbreviation. By adding the strength agent, finished pulp molding plastic products, the strength will be higher than without at least 2 ~ 3 times, such as compressive strength, tensile and bending deformation, such as using persistent will get promoted.

Generally, to improve the quality of products at the same time can be used within the scope of the minimum cost of production technology is the best, the practical application of molded pulp products additives on the product quality improvement, is fully illustrated production resources rational allocation and utilization in order to create high value products.
