What kind of gas is ASA after drying

ASA (Acrylonitrile Styrene Acrylate Copolymer) engineering plastic is a graft copolymer of acrylic rubber body, acrylonitrile and styrene. Specific gravity: grams cubic centimeter molding shrinkage:

Molding temperature: 170-230 Drying conditions: 80-90 for 2 hours.

1. ASA has good mechanical and physical properties.

ASA and ABS are structurally similar and are composed of acrylonitrile and butadiene rubber, which retains the excellent mechanical and physical properties of ABS as an engineering plastic.

2. ASA has strong weather resistance.

If the polymer contains double bonds, the double bonds are easy to be opened by the ultraviolet rays in the sunlight with greater energy intensity, resulting in the decline of the aging resistance of the polymer, and ASA is to replace the butadiene rubber containing unsaturated double bonds in ABS with acrylic rubber without unsaturated double bonds, therefore, it can not only resist the degradation, aging and fading caused by ultraviolet radiation, but also have a strong guarantee for the decomposition or discoloration caused by high temperature in the process of oxidation processing in the atmosphere. As a result, the anti-aging and weather-resistant properties of the material are greatly improved. According to the test results, the anti-aging performance of ASA is more than 10 times that of ABS.

3. ASA has good high temperature resistance.

4. ASA is an anti-static material, which can make the surface less dusty.

ASA has been widely used in high-end bathrooms and sanitary products, hot and cold water exchangers, etc., due to its long-lasting surface and color stability, which shows that ASA also has corrosion resistance to detergents and disinfectants.

Thinking about the fat deer is in a hurry.

Indoor pollution includes decoration panels, paints, latex paints, adhesives.

After decoration, decoration coatings will release some harmful gases, such as formaldehyde, benzene, ammonia, etc.

The main aspects of indoor air pollution are volatile organic compounds (TVOC), formaldehyde, ammonia, benzene, toluene, xylene, and radioactive gas radon in paint, plywood, particleboard, foam filler, interior wall coating, plastic veneer and other materials, especially splints, and the glue used in splints volatilizes formaldehyde for the longest time. The release cycle of formaldehyde is generally 3 15 years, and the release rate of volatile organic compounds such as benzene, toluene, and xylene is relatively fast, generally in 7 45 days. And in addition to removing formaldehyde on the surface, it is better to remove formaldehyde from the deep pollution source, and now there is a good way to remove formaldehyde is to remove formaldehyde material Maya Blue, which can be developed according to the release characteristics of formaldehyde, which can decompose formaldehyde well.

The main reasons for excessive formaldehyde are: excessive use of adhesives in decorative materials, and formaldehyde in paints.

There are many ways to solve excessive formaldehyde:

1. Plant adsorption, put some spider plant plants to absorb.

2. Ventilate more and put some decomposition materials, such as activated carbon and coconut carbon materials.

3. Formaldehyde removal is not required to be fast, and long-term decomposition is very important.
