The anti-dispersion solution for asbestos, "ND Lock," which we have developed, is the new and innovative product. This is a solidification solution, which modifies asbestos and prevents dispersion of asbestos by decomposing asbestos fibers at ordinary temperature and crystallizing them. It helps keep the general environment and work environment safe.
The ND Lock solution, which uses water as solvent and contains no volatile component, is an inorganic solution and has no affect on the human body (As a familiar example, it can be regarded as a component of sulfur simple hot spring. As it is an alkali solution, prolonged skin contact may cause skin irritation.)
| ND Lock solution | Other solutions | |
|---|---|---|
| Main components | Calcium polysulfide | Acrylic resin vinyl chloride resin, ethylene resin |
| Impregnation rate | High | Low |
| Aging degradation | The effect persists for years (Rework is unnecessary) Property of inorganic material Longevity |
Rework is required due to aging degradation Likely to experience aging degradation as organic material is contained |
| Work | Easy to work due to its water solubility | Measures for organic solvent and excess intensity are partially required |
| Mechanism of anti-dispersion | The dispersion is prevented by modifying the inside of asbestos Needle-like fibers are ballooned and modified |
Sealing of asbestos: Dispersion prevention removal by film Sealing of asbestos: Wetting agent |
| Retention capacity of characteristics and function of asbestos on the intended use | Characteristics and function of asbestos on the intended use are retained | Characteristics and function of asbestos on the intended use are reduced. (fire resistance, sound insulation, dew condensation prevention) |
| Dispersion of asbestos during the removal work | Because of high impregnation rate and repeating impregnation, the possibility of dispersion is low The security of asbestos removal work is improved. |
Damaging the coated layer during the asbestos removal work increases the dispersion |
