Experimental Demonstration of Automatic Film Applicator Coating High Viscosity Silica Gel on Nonwoven Fabrics

NBCHAO Film Coating Machine No. n+1 Application Experiment: Scratch Coating High Viscosity Silicone Gel on Non-woven Fabric!

Non-woven fabric is a kind of textile formed by thermal melting, spraying, chemical or mechanical treatment of fibers. It is not woven like traditional textiles, but is formed by combining and bonding fibers. Non-woven fabrics have the characteristics of light weight and good air permeability. Therefore, general non-woven fabrics cannot be kept flat by vacuum adsorption, and can only be fixed with clamps before and after.

Silica gel is a highly absorbent material made of silicate-like compounds. It absorbs a lot of liquid and has good drying and moisture management capabilities. Features: high viscosity, non-toxic, tasteless, good stability. High-viscosity samples are generally coated with a drawdown blade, and wire Bar Coaters are not suitable for high-viscosity sample coatings.

There are many applications for coating high-viscosity silicone gel on non-woven fabrics. In the medical field, coating high-viscosity silicone gel on non-woven fabrics is often used to make dressings and band-aids. In the industrial field, it is often used in oil-absorbing materials, industrial wipes and oil-absorbing pads. In addition, it can also be used as a cooling system in the aerospace automotive industry and as a high-performance waterproof, breathable and windproof clothing in the prevention industry.

Let's take a look at how Beichao Technology uses an automatic film coating machine to coat high-viscosity silicone gel on non-woven fabrics. The video demonstrates in detail.

Because the viscosity of silicone gel is relatively high, the speed of scraping should be well controlled, and the speed should be slower. And it's best to add ingredients while scraping. The final effect of the coating film is still dripping.
