Research on Modification of 3A Molecular Sieve Raw Powder

Silane coupling agent KH-550 to modify the surface of 3A molecular sieve raw powder, investigated the effects of coupling agent dosage (mass fraction) and modification time on the viscosity of activated powder oil slurry of molecular sieve, and compared the static water adsorption capacity, phase, particle size distribution, and shelf life of the samples before and after modification.

Introduction to silane coupling agent KH-550
The chemical name of silane coupling agent KH-550 is gamma aminopropyltriethoxysilane, which is an important coupling agent in the chemical industry. Due to its unique molecular structure, it can bridge the gap between inorganic and organic materials, significantly improving the overall performance of the material.

The impact of modified conditions

The research results indicate that with the increase of coupling agent dosage and the extension of modification time, the viscosity of activated powder decreases. The optimal modification conditions are a coupling agent dosage of 1.0% and a modification time of 45 minutes.
Other application scenarios of silane coupling agent KH-550
Fiberglass Reinforced Plastic (FRP)
By using KH-550 for surface treatment of glass fibers, the interfacial bonding between glass fibers and resin matrix can effectively improve, thereby enhancing the mechanical properties and durability of composite materials. Experiments have shown that the tensile strength and bending strength of glass fiber composite materials treated with KH-550 have significantly increased by 3.

In the field of coatings and adhesives

Adding it to coatings or adhesives can significantly improve the adhesion, water resistance, and weather resistance of the coating. Especially in water-based coatings, KH-550 can effectively solve the interface problem between water-based resin and substrate, making the coating more uniform and firm.Surface modification of other materials
KH-550 has also played an important role in surface modification of materials such as ceramics and metals. By processing with KH-550, the surface activity of these materials can effectively improve, enhancing their bonding strength with other materials, and thus widely use in high-tech fields such as electronic packaging and aerospace.
Precautions for use
KH-550 should store in a dry and ventilated environment, avoiding contact with moisture to prevent hydrolysis reactions. During use, the dosage and processing technology should adjust according to the specific application scenario to achieve the best effect.
