The difference between wood pulp cotton and sponge:

The difference between wood pulp cotton and sponge:
1, the two definitions are different
Sponge: A porous material that is highly absorbent and can be used to clean items.
Wood pulp and cotton (wood fiber): organic flocculent fibrous material obtained from natural renewable wood through chemical treatment and mechanical processing.
2. The raw materials of the two are different
Sponges: Made from wood cellulose fibers or foamed plastic polymers, there are also natural sponges made from sponge animals.
Wood pulp cotton (wood fiber): Chemically treated from natural renewable wood.
3. The two have different uses
Sponge: It has good water absorption and can be used for cleaning items, and natural sponges can also be used for body cleaning or painting.
Wood pulp cotton (wood fiber): used in concrete mortar, gypsum products, asphalt roads and other fields. It can be used in the manufacture of MDF and used in the home building materials industry.
4. The characteristics of the two are different
Sponge: Polyurethane soft foamed rubber, polyurethane is a common polymer material in life, with shock-absorbing and anti-friction properties.
Wood pulp and cotton (wood fiber): non-toxic, odorless, non-polluting, non-radioactive, insoluble in water, heat preservation, and structurally viscous.
5. The specific applications of the two are different
Sponge: It can be used as shoe sole, tractor tank track substrate; can be used as swivel chair sofa cushion, back cotton; can be used as flame retardant fire extinguisher.
Wood pulp cotton (wood fiber):
Compressed wood pulp wool is widely used in concrete mortar, gypsum products, asphalt roads and other fields. It is useful for preventing coating cracking, improving water retention, improving production stability and construction suitability, increasing strength, and enhancing adhesion to the surface. good effect. Its technical functions are mainly: thixotropy, protection, absorption, carrier and filler.
Due to the capillary action of the fiber structure, the moisture inside the system is rapidly transported to the surface and interface of the slurry, so that the moisture inside the slurry is uniformly distributed and the skinning phenomenon is significantly reduced. And make the bond strength and surface strength significantly improved, this mechanism also plays a significant role in crack resistance due to the reduction of tension in the drying process.
The dimensional stability and thermal stability of wood fiber play a good role in thermal insulation and crack resistance in thermal insulation materials.
