Comparison of G-MAQ with conventional technology
G-MAQ is nurtured through relentless daily research and development.
| Adsorption and deodorisation technology | Main product examples | Adsorption and deodorisation principle | Advantage | Disadvantages |
|---|---|---|---|---|
| Masking | Air fresheners, many commercial deodorisers, etc. | This conceals unpleasant odours by coating malodorous substances and harmful chemical components with aromatic ingredients, making them less directly perceivable. | ◾️ Many are relatively low-cost. | ◾️ As harmful chemical substances and odour-causing substances remain as they are, it is not deodorisation in its true sense. The aromatic ingredients may not be to the user's taste. Cannot be used for hazardous chemical substance countermeasures. ◾️ Some aromatic ingredients themselves are harmful to the human body, etc. |
| Physisorption | Activated carbon, zeolite, silica gel, diatomaceous earth, etc. | To reduce the concentration of surrounding harmful chemical substances and malodorous substances by adsorbing them onto the porous parts of the surface of porous materials. | ◾️ Many are relatively low-cost. ◾️ Due to the porous nature enabling adsorption of substances of suitable size, many possess a wide range of applicable substances for adsorption and deodorisation, often proving advantageous for complex odours. In a dynamic environment, many substances have a fast adsorption rate. | ◾️Re-emission of adsorbed harmful chemicals and malodour-causing substances is likely to occur due to factors such as humidity and temperature. When compared with chemisorption, the adsorption capacity is often smaller. If the porous part and the size match, substances other than harmful chemicals and causes of bad odours (especially water, dust, and tar) will also be adsorbed, resulting in a significant loss of adsorption capacity for the target substance in actual use. ◾️The functionality is dependent on the form, resulting in low suitability depending on the situation and purpose. |
| Chemisorption | Some commercially available deodorisers and sick house syndrome countermeasures, etc. | To deodorise and detoxify by using chemical reactions to adsorb, neutralise, transform and decompose harmful chemical substances and malodorous substances. | Once adsorbed, it is unlikely that harmful chemical substances and malodorous substances will be re-emitted. Compared to physisorption, chemisorption often has a larger adsorption capacity. ◾️ By chemically reacting, adsorption and deodorisation targeting specific hazardous chemical substances and malodour-causing substances can be achieved with minimal loss of adsorption capacity for the target substances. When compared to physical adsorption, it often has higher suitability depending on the situation and purpose. | Many products exhibit poor stability of their adsorbing and deodorising components, leading to significant performance degradation over time. ◾️ Some adsorption and deodorising ingredients themselves are harmful to the human body, metals, etc. ◾️Many substances used for adsorption and deodorisation of harmful chemicals and malodorous substances through chemical reactions have a biased polarity for target substances (those effective against acidic odours are not effective against alkaline odours, and vice-versa), making them disadvantageous for the adsorption and deodorisation of complex odours. |
| G-MAQ Chemical adsorption by graft copolymer | G-MAQ Products | Neutralises and detoxifies by using chemical reactions to adsorb, neutralise and convert harmful chemical substances and malodorous substances. | Once adsorbed, it is unlikely that harmful chemical substances and malodorous substances will be re-emitted. ◾️ By chemically reacting, adsorption and deodorisation targeting specific hazardous chemical substances and malodour-causing substances can be achieved with minimal loss of adsorption capacity for the target substances. Due to the three-dimensional arrangement of functional groups (adsorption and deodorising components) via graft polymerisation, it is easy to achieve faster adsorption speeds and larger adsorption capacities compared to physical adsorption or conventional chemical adsorption. ◾️ Graft polymerisation allows various functional groups with different adsorption and deodorising properties to be imparted to substrates with diverse physical properties and shapes. This makes it easier to enhance suitability for specific situations and purposes compared to physical adsorption or conventional chemical adsorption. As it is a polymer, it has high stability. Unlike conventional chemical adsorbents, its performance degradation over time is extremely low, and it is also highly safe for human bodies and other organisms. | When compared to excellent physical adsorbents, cases may be seen where it is inferior in adsorption speed in a dynamic environment and its ability to cope with complex odours. |
| Other | Photocatalyst, Stabilised Chlorine Dioxide, Plant-derived Extract, Metal Ion, Ozone, etc. | It demonstrates excellent performance when used appropriately for its intended purpose. | It includes those with a short duration of effect. This includes things that take a long time to show results. ◾️ Depending on the application, some may include effects that are not proven. - Some active ingredients themselves are also found to be harmful to humans, metals, etc. Partly, they also generate substances harmful to the human body and metals. |
