ceramic membrane

The ceramic membrane is an asymmetric membrane formed by inorganic ceramic materials prepared by a special process. It is divided into two types: tubular ceramic membrane and flat ceramic membrane.

The ceramic membrane has high separation efficiency, good chemical stability, acid and alkali resistance, organic solvent resistance, bacteria resistance, high-temperature resistance, pollution resistance, high mechanical strength, good regeneration performance, simple separation process, low energy consumption, and long service life.

Application fields:

  • Food industry

  • Plant (medicine) deep processing

  • Biomedicine

  • Fermentation

  • Fine chemicals

Characteristics of ceramic membrane materials:
A coating film is required on the surface of the ceramic. The coating film is to apply a filter layer. The material used depends on the pore size，100 nm is 99.995% alpha-alumina, 50-30 nm is 99.99% zirconia, and 10 nm is 99.95% Titanium oxide.
  • Support carrier: imported white corundum.

  • Microfiltration membrane: imported 99.995% purity alpha-alumina.

  • Ultrafiltration membrane: Hejal's core invention patent, monodispersed 99.99% zirconia/titanium oxide.

Source: https://www.innovacera.com/news/ceramic-heater-coil-for-vaporizer.html Not every dry herb vaporizers are the same! Especially those used ceramic heating element. The ceramic heating element is a safety and healthiest option for dry herb vaporizers, so every vaper is preferred to choose those vaporizers that carry ceramic heating element. The proponents believe that the heating element is the core of the vaporizer and primarily dictates the experience of the taste. Let's more specific, when a vaper burns tobacco, marijuana, or hemp during traditional smoking to release the active component, whatever it's nicotine, CBD, or THC, they inhale the smoke. We all know that's not good for health. Rather than burning, Vaporizer heats the liquid, wax or even dry herb to release a vapour, and a vaper inhales the vapour without any damage to their lungs or throat. And why the ceramic heating element is becoming the core part of the vaporizer? It's mainly because: 1. Ceramic ...

BAN combines  Aluminum Nitride with Boron Nitride , a hybrid machinable Aluminum Nitride ceramic with excellent thermal conductivity, high strength, and resistance to thermal shock. Innovacera provides BAN, and it has very similar properties to SHAPAL material. SHAPAL is a trademark of Tokuyama Corporation.   These ceramics are used in various industries, including electronics, semiconductor manufacturing, aerospace, automotive and medical. BAN ceramics have properties that make them suitable for applications such as  heat sinks , heater substrates, semiconductor processing components, and optical equipment.   Material Advantages : High mechanical strength. High thermal conductivity. Low thermal expansion. Low dielectric loss. Excellent electrical insulation. High corrosion resistance–non-wetted by molten metals. Excellent Machinabilit–BAN can be machined to high-precision complex shapes. It has excellent sealing ability to vacuum and hasn’t given off much gas. High-...
