2021-11-05   Pageview:696

1, JL-B50 is a light green transparent solution, PH <5.0, stable at pH 2-8.5.

2, Stable: not easy to decompose, good compatibility with emulsion paint and additives, uniform dispersion, does not affect the performance of water-based emulsion paint.

3, Environmental protection: that is, high safety, no harm to human health, no harmful effects on the environment.

4, High efficiency: that is, strong anti-mold power, with less drug dose can kill or inhibit the reproduction and growth of mold.

5, Non-oxidizing fungicidal preservative, good compatibility with emulsion under the conditions of use concentration, no formaldehyde, no VOC, environmental protection and water, low molecular alcohol miscibility, simple operation.












Silane coupling agent application method
The application of silane coupling agent is to treat inorganic fillers, substrates or directly add paint. The filler is treated with a silane coupling agent, and its surface changes from hydrophilic to organophilic. This kind of surface can not only avoid particle aggregation and sharp adjustment of polymer in the system, but also improve the wettability of organic polymer to the reinforcing filler. Through the carbon-containing functional group in the coupling agent, the reinforcing filler can be firmly bonded to the polymer. After the inorganic substrate is processed, the critical surface tension that matches the resin or solvent can be obtained, which is conducive to the infiltration of the coating on the substrate. It is a method to use the coupling agent directly in the primer when processing the substrate. There is also a method called integral blending, that is, the stock solution or solution of the silane coupling agent is directly added to the coating mixture. The application methods of silane montan wax price coupling agent are respectively introduced below.

1. Calculation of the amount of silane coupling agent to treat the filler
The wettable area (WS) of the silane coupling agent refers to the area (m*/g) of the substrate that can be covered by a solution of 1 g of the silane coupling agent. If the wettable area of ​​the silane is correlated with the specific surface area of ​​the filler (m²/g), the amount of silane coupling agent required for monolayer coverage can be calculated.
Filler mass (g) × filler specific surface area (m²/g) silane dosage (g) = silane wettable area (m³/g) Table 16-9 lists the surface area (S) values ​​of some common fillers.
When the silane coupling agent is used to treat the filler, it is also necessary to determine whether the water content of the filler can meet the needs of the hydrolysis reaction of the silane coupling agent. Table 16-10 lists the minimum amount of water required for the hydrolysis reaction of certain silane coupling agents.
