1, permeability
PP rod and sheet,a high density,non-side chain and high crystallinity linear polymer,PP rod and sheet have excellent comprehensive properties.
PP Rod and sheet have many good properties:lower density,heat resistance,non-deformation,high rigidity,high surface strength,good chemical stability,excellent electric performance,non toxic,etc.
PP rod and sheetare widely applied to spray carrier corrosion tank,bucket,acid and alkali industry,waste water,waste gas discharge equipment,washing tower,dust free room,semiconductor,electroplating process,etc
The process by which the molecules of the chemical pass through the protective gloves is as follows:
1 The molecules of the chemical are absorbed by the contact of the material;
2 the absorbed molecules diffuse within the material;
3 chemical molecules appear on the other side of the material.
2, penetrating
Chemicals or microorganisms pass non-molecularly on porous materials, seams, pinholes or other gloves. Penetration tests include leak testing and water leak testing.
3. Degradation
The protective glove material undergoes a destructive change in one or more mechanical properties in contact with the chemical. The test focus of degradation is:
1 change in tensile strength (change in final tensile strength before and after exposure to chemicals);
2 expansion index.
