1. Definition and classification of polyurethane composite anti-heartburn agent
Polyurethane composite anti-heartburn agent is a multifunctional additive specially designed to improve quality problems in glass production. It is mainly composed of polyurethane substrates and other functional additives, which can effectively inhibit surface defects caused by chemical reactions or physical phenomena in the melting stage of glass. According to its mechanism of action and composition differences, polyurethane composite anti-heartburn agents can be divided into the following categories:
-
Physical anti-living agent
This type of anti-heartburn agent mainly reduces surface defects by regulating the fluidity of the glass molten liquid. For example, certain polyurethane materials of certain structures can form a protective film at high temperatures to prevent pits caused by cracking when bubbles float. The advantage of this type of product is that it is simple to operate and is suitable for ordinary glass products with low chemical requirements. -
Chemical anti-living agent
Chemical anti-centrifuge agents focus on participating in and optimizing chemical reactions during glass melting. They usually contain active ingredients that promote impurities decomposition or accelerate gas escape, thereby significantly reducing the possibility of bubble residue. This type of anti-heartburn agent is suitable for the manufacture of special glasses with high precision requirements, such as optical glass or electronic grade glass. -
Comprehensive anti-living agent
Comprehensive anti-centrifuge agents combine physical and chemical mechanisms, which can not only reduce bubble generation by changing the chemical environment, but also improve surface quality by adjusting melt flow. Due to its versatility and adaptability, this type of anti-heartburn agent has gradually become the mainstream choice in the market.
Table 1: Main categories and characteristics of polyurethane composite anti-heartburn agents
Category | Main Functions | Applicable scenarios | Advantages |
---|---|---|---|
Physical | Improve melt flow and reduce surface pits | Ordinary flat glass, architectural glass | Easy to operate and low cost |
Chemical type | Participate in chemical reactions to reduce bubble generation | Optical glass, electronic grade glass | Efficiently remove tiny bubbles |
Comprehensive | Effect both physical and chemistry at the same time | Multi-purpose glass, such as automotive glass, photovoltaic glass | Comprehensive functions and strong adaptability |
The reason why polyurethane composite anti-heartburns stand out in the glass industry is largely due to their unique molecular structure design. By combining additives with different functions with polyurethane substrates, it can flexibly respond to various complex production conditions and meet diverse product needs. Whether it is high-end optical glass that pursues extreme transparency or large-scale industrial production that focuses on economics, polyurethane composite anti-heartburn agents can provide an ideal solution.
2. The mechanism of action of polyurethane composite anti-heartburn agent
The key reason why polyurethane composite anti-heartburn agent can significantly improve the quality of glass products is its unique mechanism of action. This process involves complex interactions at multiple levels, including physical adsorption, chemical reactions, and interface regulation. The following is a specific analysis of its core mechanism of action:
(I) Physical adsorption and isolation effects
Impurities in raw materials during the melting process of glass(such as carbonate, sulfate, etc.) will decompose and produce gases at high temperatures, which will gradually accumulate and form bubbles. If the bubbles cannot be discharged in time, they will solidify on the inside or surface of the glass after cooling, resulting in obvious defects. The polyurethane composite anti-heartburn agent forms a dense protective film on the surface of the molten liquid through its unique molecular structure. This film has excellent physical adsorption capability and can effectively prevent bubbles from contacting directly with the glass surface, thereby avoiding pits or other damage caused by bubble burst.
Specifically, long-chain molecules in polyurethane substrates can quickly diffuse to the surface of the molten liquid and firmly adhere to the glass substrate by van der Waals force. At the same time, the functional additives in the anti-heartburn agent will further enhance the stability and toughness of the membrane layer, allowing it to maintain integrity under high temperature environments. This physical isolation effect not only reduces the impact of air bubbles on the glass surface, but also effectively delays the migration rate of other harmful substances (such as metal ions) to the inside of the glass, thereby reducing the probability of deep defects.
(Bi) Chemical catalysis and reaction optimization
In addition to physical adsorption, polyurethane composite anti-heartburn agent also actively participates in the glass melting process through chemical reactions. The catalyst components contained in it can significantly accelerate the decomposition rate of impurities in the raw material, so that the generated gas can quickly escape without retention in the molten liquid. For example, when calcium carbonate decomposes to form carbon dioxide, acidic functional groups in the anti-heartburn agent will neutralize it, reducing the solubility of carbon dioxide and prompting it to be released from the molten liquid more quickly.
In addition, anti-cardiosaccharides can also optimize the entire chemical reaction environment by regulating the pH of the molten liquid. Studies have shown that an appropriate pH range can help improve the stability of the silicate network and reduce stress concentration caused by local overheating or uneven cooling. This chemical regulation not only improves the overall uniformity of the glass, but also provides better basic conditions for its subsequent processing.
(III) Interface regulation and liquidity improvement
The flow performance of glass molten liquid is one of the important factors that determine the quality of the final product. If the molten liquid is too viscous, it may cause the bubbles to be difficult to discharge smoothly; while too low viscosity may easily cause problems such as droplet separation. Polyurethane composite anti-centrifuge agent cleverly balances the viscosity and fluidity of the molten liquid through interface regulation technology, ensuring that it always maintains an ideal state throughout the entire production process.
The surfactant component in the anti-heartburn agent can significantly reduce the interfacial tension of the molten liquid, thereby making it easier for the bubbles to detach from the liquid surface and escape into the air. At the same time, its special molecular structure can effectively prevent the occurrence of layering or agglomeration of molten liquid, ensuring the consistency and continuity of the glass matrix. This interface regulation capability is particularly important for the production of large or ultra-thin glass products, as it can significantly reduce thickness deviations and optical distortion problems caused by uneven flow.
(IV) Temperature stability and long-term protection
It is worth mentioning thatPolyurethane composite anti-living agents also exhibit extremely high temperature stability. Even under extreme conditions up to 1500°C or above, its molecular structure can still be kept intact and will not decompose or fail. This excellent thermal stability allows the anti-cardiocarciner to continue to function until the glass is completely cooled and molded. Compared with traditional single-function additives, the long-term protective properties of polyurethane composite anti-heartburn agents undoubtedly won it higher ratings.
To sum up, polyurethane composite anti-centrifuge agent successfully solved the common bubbles, stripes and other surface defects in glass production through the synergistic effect of various mechanisms such as physical adsorption, chemical catalysis, interface regulation and temperature stability. Its emergence not only greatly improves the quality of glass products, but also brings new directions of technological change to the entire industry.
III. Product parameters and technical indicators of polyurethane composite anti-heartburn agent
In order to better understand the actual performance of polyurethane composite anti-heartburn agents and their applicability in different scenarios, we need to have an in-depth understanding of its specific technical parameters and product specifications. The following will be explained in detail from multiple dimensions such as appearance, physical properties, chemical characteristics, and usage conditions.
(I) Appearance shape
Polyurethane composite anti-heartburn agents are usually present in powder or granular form for easy storage and transportation. Its colors are mostly light gray or white, with no obvious odor, and have good dispersion. This design not only facilitates users to add it evenly to the glass raw materials, but also effectively avoids the impact of production efficiency due to agglomeration or precipitation.

Table 2 shows the main physical properties parameters of polyurethane composite anti-heartburn agent:
parameter name | Unit | Value Range |
---|---|---|
Density | g/cm³ | 0.8-1.2 |
Particle Size | μm | 10-100 |
Melting point | ℃ | 120-150 |
Hydragonism | % | ≤0.5 |
It can be seen from the table that the moderate density of the product not only ensures its good suspension in the molten liquid, but does not settle to the bottom due to excessive weight. The particle size distribution range is narrow, which helps to achieve a more uniform dispersion effect. In addition, its low moisture absorption rate also ensures the stability of the product in humid environments and extends the shelf life.
(III) Chemical Characteristics
As a functional additive, the chemical properties of polyurethane composite anti-heartburn agents are crucial. The following is a summary of its main chemical parameters:
parameter name | Description |
---|---|
pH value | Neutral or weakly alkaline (7-9) |
Active ingredient content | ≥95% |
Impurity content | ≤0.1% |
Cream residue | ≤0.05% |
These parameters show that polyurethane composite anti-heartburn agents have high purity and low impurity content, which can greatly reduce contamination on finished glass products. In particular, the level of control of combustion residues is much lower than industry standards, which means it leaves almost no trace in high temperature environments, thus ensuring absolute cleanliness of the glass surface.
(IV) Conditions of use
In practical applications, polyurethane composite anti-heartburn agent needs to meet certain conditions of use before it can fully exert its effectiveness. The following are the recommended usage parameters:
parameter name | Recommended Value |
---|---|
Add ratio | 0.1%-0.5% by weight |
Using temperature | 1400-1600℃ |
Stirring time | ≥10 minutes |
Cooling rate | Contained at 50-100℃/hour |
It should be noted that the specific addition ratio and use temperature should be adjusted appropriately according to the type of target product and production process. For example, for optical glass with high precision requirements, it is recommended to use a higher additive ratio to ensure good results; for ordinary building glass, the amount used can be appropriately reduced to save costs.
Through the detailed introduction of the above parameters, we can clearly recognize the superiority of polyurethane composite anti-heartburn agents in performance and their flexibility in actual operation. It is these precise designs and strict controls that make it an indispensable and important tool in the modern glass manufacturing industry.
