The advantages of self-crusting pinhole eliminator in the production of high-end shoe materials: improving yield and market competitiveness

Introduction

In the production process of high-end shoe materials, the quality and appearance of the material are the key factors that determine the competitiveness of the product market. As a highly efficient chemical additive, self-crusting pinhole eliminator has been widely used in shoe material production in recent years. This article will discuss in detail the advantages of self-crusting pinhole eliminators in the production of high-end shoe materials, analyze how it improves yield and market competitiveness, and provide a comprehensive technical analysis through rich product parameters and references from domestic and foreign literature.

1. Definition and mechanism of self-cutting pinhole eliminator

1.1 Definition

Self-crusting pinhole eliminator is a chemical additive specially used to eliminate pinholes on the surface of polyurethane (PU) materials. It effectively reduces or eliminates tiny holes on the surface of the material by improving the rheological properties and surface tension of the material, thereby improving the surface quality and mechanical properties of the product.

1.2 Mechanism of action

Self-cutting pinhole eliminator mainly works in the following ways:

Surface tension adjustment: Reduce the formation and retention of bubbles by reducing the surface tension of the material.
Rheological performance improvement: Optimize the fluidity and viscosity of the material to make bubbles easier to discharge.
Chemical reaction promotion: Chemical reaction with other components in the material to form a stable surface structure.

2. Application of self-crusting pinhole eliminator in the production of high-end shoe materials

2.1 Improve the yield rate

In the production of high-end shoe materials, yield is an important indicator for measuring production efficiency. Self-crusting pinhole eliminator improves yield by:

Reduce surface defects: Effectively eliminate pinholes and bubbles on the surface of the material and reduce defective rates.
Reinforced material strength: Improve the mechanical properties of the material and reduce breakage and damage caused by material defects.
Optimize production process: By improving the rheological performance of materials, simplifying production processes and improving production efficiency.

2.2 Improve market competitiveness

The high-end shoe materials market is fierce, and product quality and appearance are key factors that attract consumers. Self-crusting pinhole eliminator enhances market competitiveness by:

Improve product appearance quality: Eliminate surface pinholes and make the product appearance outsideThe view is smoother and more beautiful.
