Keywords Sponge hardener; soft foam; production process; raw material selection; finished product inspection; quality control

Introduction

Soft foam products are widely used in furniture, automobiles, packaging and other fields, and their performance directly affects the quality and user experience of the final product. With the increasing demand for high-performance and environmentally friendly foam products in the market, optimizing production processes and improving product performance have become the focus of industry attention. As an innovative additive, the new generation of sponge hardener provides new solutions for the performance improvement of soft foam products.

This article aims to explore how to use the new generation of sponge hardener to optimize the production process of soft foam products, and conduct in-depth analysis of the entire process from raw material selection to finished product inspection. By systematically explaining the mechanism of action, raw material selection strategies, production process optimization methods and quality control measures of hardener, we provide practical technical guidance to relevant enterprises.

The significance of this study is: first, help enterprises understand the characteristics and application value of the new generation of sponge hardeners; second, provide comprehensive production process optimization solutions to improve product quality and production efficiency; then, through strict quality control and finished product inspection, ensure that product performance meets market demand. The research results of this article will provide strong support for the innovative development of the soft foam products industry.

1. Characteristics and applications of the new generation of sponge hardener

Sponge hardener is an additive that can significantly improve the hardness and mechanical properties of soft foam products. Its mechanism of action mainly involves two aspects: one is to form a crosslinked structure by chemical reaction with the foam matrix to enhance the interaction force between molecules; the other is to use as a filler to increase the density and strength of the foam. The new generation of sponge hardener has made many improvements based on traditional products, with higher reactivity, better dispersion and lower volatility.

Compared with traditional hardener, the new generation of products has the following advantages: First, its active ingredients content is higher and its added amount is smaller, which can effectively reduce production costs; second, it is with various foam substratesThe compatibility is better and the phase separation phenomenon is not easy to occur; again, the environmental protection performance is significantly improved, and the emission of volatile organic compounds (VOCs) is greatly reduced; after that, the impact on other properties of foam products (such as rebound and durability) is less, which is conducive to maintaining the comprehensive performance of the product.

In terms of application effects in soft foam products, the new generation of sponge hardener has performed well. Taking polyurethane soft bubbles as an example, after adding an appropriate amount of hardener, the hardness of the product can be increased by 20%-40%, the compression permanent deformation rate is reduced by 15%-30%, while the elasticity and breathability are basically unchanged. In addition, hardeners can also improve the processing performance of foam, such as shortening maturation time and reducing the difficulty of mold release. These advantages have enabled the new generation of sponge hardener to be widely used in the fields of car seats, furniture cushions, packaging materials, etc.

2. Raw materials selection for soft foam products production process

Selecting the right raw materials is the basis for optimizing the production process of soft foam products. Polyurethane (PU) is the main raw material for making soft foams, and its choice should take into account parameters such as molecular weight, functionality, and hydroxyl value. Generally, high molecular weight and low functional PUs can produce softer foams, while low molecular weight and high functional PUs are conducive to improving foam hardness. In addition, factors such as PU viscosity and reactive activity need to be considered to ensure good processing performance.

The selection of auxiliary raw materials is equally important. Catalysts can adjust the reaction rate, and common varieties include amine and organotin catalysts. Foaming agents affect the density and structure of foam. Currently, water is widely used as a chemical foaming agent, supplemented by physical foaming agents such as cyclopentane. Surfactants can stabilize the foam structure and improve the uniformity of the cells. Fillers such as calcium carbonate, talc powder, etc. can adjust the foam hardness and cost, but attention should be paid to their impact on processing performance and product appearance.

Raw material ratio is a key factor affecting the performance of the final product. Taking PU soft bubbles as an example, PU accounts for 60%-80%, water 2%-4%, catalyst 0.5%-2%, surfactant 1%-2%, and the rest are fillers and other additives. The specific ratio should be adjusted according to product requirements. For example, to increase the foam hardness, the proportion of high-functional PU can be appropriately increased, or more fillers can be added; if resilience is to be improved, high molecular weight PU can be selected and the type and amount of catalysts can be optimized.

3. Optimization strategy for production process flow

Optimization of production process flow is the key to improving the quality and production efficiency of soft foam products. First, during the raw material pretreatment stage, the storage conditions and feeding order of raw materials should be strictly controlled. PU and auxiliary raw materials need to be stored under constant temperature and humidity conditions, and should be fully stirred before feeding to ensure uniformity. For solid fillers, it is recommended to pre-ground and sieved to improve dispersion.

During the mixing and foaming phase, it is crucial to optimize the stirring speed and time. Generally, the stirring speed is controlled at 1000-3000rpm, and the time is 30-60s. Too high or too low agitation speed will affect the cell structure. The foaming temperature is generally controlled at 25-35℃. Too high may lead to excessive reaction, while too low may affect the foaming effect. The mold design should consider the shape, size and mold release convenience of the product, and reasonably set the exhaust holes and mold release slope.

The optimization of the maturation and post-treatment phases can significantly improve production efficiency. The maturation temperature is usually set at 80-120°C, and the time is 2-4 hours. The performance of the product can be improved by using a segmented maturation process (such as low temperature first and high temperature). Post-treatment includes trimming, grinding and other processes, and appropriate tools and methods should be used to reduce material losses and improve surface quality. In addition, it is possible to consider introducing automation equipment, such as robotic arm trimming, laser cutting, etc., to improve production efficiency and consistency.

IV. Quality control and finished product inspection methods

Establishing a complete quality control system is the key to ensuring the stable performance of soft foam products. First, detailed raw material inspection standards should be formulated, including indicators such as molecular weight distribution, hydroxyl value, and viscosity of the PU, as well as parameters such as purity and activity of the auxiliary raw materials. Advanced analytical methods such as infrared spectroscopy and gel permeation chromatography can be used to characterize raw materials.

In the production process, full-process monitoring should be implemented. Key control points include: raw material ratio accuracy, mixing uniformity, foaming temperature and time, maturation conditions, etc. An online monitoring system can be introduced to collect and analyze data in real time, and to promptly detect and correct deviations. In addition, production equipment is regularly calibrated and maintained to ensure the accuracy and stability of process parameters.

Finished product inspection is an important part of quality control. The main testing items include: hardness, density, elasticity, compression permanent deformation, tensile strength, tear strength and other physical properties; flame retardancy, VOC emission and other safety and environmental protection properties; as well as appearance quality such as cell uniformity, surface defects, etc. Standard testing methods such as ASTM, ISO, etc. can be used to test to ensure the comparability and reliability of the results.

Data analysis plays an important role in quality control. By establishing a database, collecting and analyzing raw materials, process parameters and finished product performance data, key influencing factors can be identified and production processes can be optimized. Statistical process control (SPC) methods can be used, such as control charts, process capability analysis, etc., to monitor the production process in real time to prevent quality problems. In addition, using big data analysis and machine learning technology, predictive models can be established to achieve early warning of quality problems and intelligent decision-making.

V. Conclusion

This study systematically explores strategies and methods for optimizing the production process of soft foam products using a new generation of sponge hardener. Research shows that the rational selection and application of the new generation of sponge hardener can significantly improve the hardness, resilience and durability of soft foam products, while reducing production costs. By optimizing raw material selection, improving production processes, strengthening quality control and finished product inspection, product quality and production efficiency can be effectively improved.

The main innovations of this study are: First, the characteristics of the new generation of sponge hardeners and their impact on the performance of soft foam products are comprehensively analyzed;Secondly, a full-process optimization strategy from raw material selection to finished product inspection is proposed; later, the application value of data analysis and intelligent technology in quality control is emphasized.

Future research directions may include: developing new, more environmentally friendly and efficient hardeners; exploring the synergistic effects of hardeners and other additives; studying the application characteristics of hardeners in different types of soft foams; and further promoting the intelligence and automation of production processes. These studies will provide new impetus for the continued innovation and development of the soft foam products industry.
