Cellulose Fiber Based Fungal And Water Resistant Insulation Materials

Place publisher year edition pages stockholm.

Cellulose fiber based fungal and water resistant insulation materials.

It does not pollute the air during manufacture or use as much energy to produce as fiberglass. To improve water resistance the foams were impregnated with hydrophobic extractives from the outer bark of birch betula verrucosa and dried. Often referred to as breathability vapor permeability describes a material s ability to allow water vapor to pass through it measured in units called perms. Materials with lower.

The surface morphology of the foams and the distribution of the deposited particles from the extractives were observed by scanning electron microscopy sem. Fiberglass fibers may become airborne which can be considered a pollutant. Two highly valuable features for insulating packaging materials especially in combination with stability in water. Get free shipping on qualified cellulose insulation or buy online pick up in store today in the building materials department.

To improve water resistance the foams were impregnated. In the present study cellulose fiber based insulation foams made of bleached chemi thermo mechanical pulp ctmp have been investigated. In the present study cellulose fiber based insulation foams made of bleached chemi thermo mechanical pulp ctmp have been investigated. Kth royal institute of technology 2017.

Cellulose fiber based fungal and water resistant insulation materials. Two highly valuable features for insulating packaging materials especially in combination with stability in water. Cellulose fiber based thermal insulation materials with fungal resistance improved water resistance and reaction to fire properties zheng chao kth school of chemical science and engineering che fibre and polymer technology wood chemistry and pulp technology. Water stable cellulose fiber foams have been produced in a simple one batch foam forming process with drying under ambient conditions.

The cellulose fiber foams have a low density 33 66 kg m3 and can inhibit microbial growth. Improper placement of materials in a wall can lead to condensation on colder surfaces water damaged insulation and building materials as well as fungal growth. Cellulose insulation is considered a greener material than fiberglass. Cellulose fiber based insulation foams made of bleached chemi thermo mechanical pulp ctmp have been investigated.

The thesis demonstrates that it is possible to produce cellulose fiber based insulation materials with improved properties in terms of fungal improved water resistance and reaction to fire properties.
