Main properties of shavings
Wood chips have a small weight. Their bulk density is approximately 220-580 kg per cubic meter, all depending on the level of humidity (standard indicators — from 8% to 15% or more). Shavings contains approximately 27% lignin, which is responsible for the wood, and 70% cellulose, hemicellulose (actually carbohydrates).
The amount of chemical components is: Nitrogen, 0.1%; Hydrogen, 6%; Oxygen, 44%; Carbon, 50%.
- size from 0.5 to 3 mm
- shipment by car chip mobile
- as sawdust is stored outdoors
- the weight depends on weather conditions
- the approximate weight of 800 kg weighs one cube
Classification of softwood sawdust
Depending on the breed of lumber, softwood sawdust is divided into: Pine sawdust. Pine sawdust has a very light color and a strong resin smell that wears off after two weeks. They are versatile and can be used for almost all types of processing and production of fiberboard, building materials resistant to high humidity. Sawdust from spruce. Sawdust in this category is darker than the previous option, but has the same pungent resinous smell.
Widely used in furniture industry, as well as in paper production. Sawdust from cedar and larch. Differ in characteristic odor and darker color. Cedar and larch sawdust are ideal for industrial biofuel production.
Spheres of application of coniferous sawdust:
- the material is used in horticulture and gardening, forestry for mulching the soil;
- it is used for the production of various crafts and interior items;
- it is used in urban landscaping for decorative mulching of bare spots of soil in the
- for decorative lawns;
