Abstract
A deterioration indicator for a resin mold member in a product includes a deteriorating state checking portion configured to allow evaluation of a deterioration state of the resin mold member. The deteriorating state checking portion includes a material whose weather resistance value, ΔE, is less than a weather resistance value, ΔE, of the resin mold member.
Claims43
A deterioration indicator for a resin mold member in a product, comprising:
- a deteriorating state checking portion configured to allow evaluation of a deterioration state of the resin mold member, said deteriorating state checking portion including a material whose weather resistance value, ΔE, is less than a weather resistance value, ΔE, of the resin mold member.
A deterioration indicator for a resin mold member in a product, comprising:
- a deteriorating state checking device configured to allow evaluation of a deterioration of the resin mold member, the deteriorating state checking device including a storing portion configured to permit water to enter and a capacity changing material provided in the storing portion and configured to change capacity when the capacity changing material absorbs water.
A method of checking a deteriorating state of a resin member in a product, comprising the steps of:
- providing a deteriorating state checking portion configured to allow an evaluation of a deteriorating state of the resin member, the deteriorating state checking portion including a material whose weather resistance value, ΔE, is smaller than a weather resistance value, ΔE, of the resin mold member;
- and
- evaluating the deteriorating state of the resin member by checking the deteriorating state checking portion.
A method of checking a deteriorating state of a resin mold member in a product, comprising the steps of:
- providing a deteriorating checking device including a capacity changing material configured to change capacity when the capacity changing material absorbs water;
- and
- checking the deteriorating state of the resin mold material by observing the deteriorating checking device.
A method of recycling a product having a resin mold material, comprising:
- providing a deteriorating state checking portion including a material whose weather resistance value, ΔE, is smaller than a weather resistance value, ΔE, of the resin mold material;
- checking a deteriorating state of the deteriorating state checking portion;
- and
- replacing the deteriorating state checking portion of the product with a new deteriorating state checking portion when the product is recycled.
