The performance test of bird's nest filament plate of the present invention is described below：
It is explained as follows on shore hardness：
Hardness (Hardness) refers to resistivity of the material to external force such as impressing, scratches.Material is represented in field of polymer technology
The softness of material.Conventional is shore (Shore) hardness.Shore hardness is used for the phase for determining the flexible materials such as plastics or rubber
To hardness.Hardometer is the table for having movable pointer in generation.It measures regulation pressing living in the case where specifying pressure and time conditions
Dynamic pointer enters measurement surface degree.Hardness number is used for identifying or specifying the plastics of special hardness.
Conventional statement is SHORE A, SHORE D and Shore OO.Principle is the same in fact, is all in standard conditions
The lower pressing by standard is pressed into the surface of standard specimen, investigates the depth of press-in to weigh the hardness of sample.Difference is pressing
Shape it is different, SHORE A and Shore OO's is truncated cone-shaped, and SHORE D then be conical.So A is used
To test flexible plastic, elastomer and elastomeric material；Shore OO measure softer material；D is used for hard plastics partially and high rigidity
Elastomer and elastomeric material；OO and A；A and D can be with overlapping statement in the range of certain degree of hardness.On resilience：
Resilience represents mattress or other similar adhesive products, and in the case where being acted on by external force, (such as human body is pressed on mattress and rested
When to pressure distortion caused by mattress) be deformed, the product restorable ability automatically after pressure is removed.Resilience be
It is pre- to be first cut into that 15cm is wide, carried out on the sample 300 of about 30cm length.At room temperature by sample along length doubling (Fig. 3 resilience
Test schematic diagram).The wide gummed tapes 301 of an about 3.7cm are taken, the sample after doubling is opened into two sections of width along sample
One layer of gummed tape is wound to fix the sample without opens voluntarily.If necessary, it is necessary in open end again laterally plus several
Bar adhesive tape.The dynamics of adhesive tape winding is just contacted with two faces of sample to be advisable.The sample fixed is placed on room temperature condition
Then remove adhesive tape within lower 8 hours, allow sample voluntarily freely to restore to the original state 1 hour.Observe the restorable speed of test agent and journey
Spend and measure some angle that can sample return to original straightened condition (180 degree angle) or sample is formed.Recover completely：Angle
A is in 175-180 degree；Do not recover：A is less than 175 degree.Sample is then considered as if not recovering angle because its resilience is bad
Unacceptable product.
