Cellulose Fiber Based Fungal And Water Resistant Insulation Materials

To improve water resistance the foams were impregnated with hydrophobic extractives from the outer bark of birch betula verrucosa and dried.

Cellulose fiber based fungal and water resistant insulation materials.

In the present study cellulose fiber based insulation foams made of bleached chemi thermo mechanical pulp ctmp have been investigated. Two highly valuable features for insulating packaging materials especially in combination with stability in water. 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. 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.

Cellulose insulation is considered a greener material than fiberglass. Materials with lower. 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. Kth royal institute of technology 2017.

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. The cellulose fiber foams have a low density 33 66 kg m3 and can inhibit microbial growth. Fiberglass fibers may become airborne which can be considered a pollutant. It is made from paper that has a minimum of 85 recycled content such as newspaper.

It does not pollute the air during manufacture or use as much energy to produce as fiberglass. Water stable cellulose fiber foams have been produced in a simple one batch foam forming process with drying under ambient conditions. In the present study cellulose fiber based insulation foams made of bleached chemi thermo mechanical pulp ctmp have been investigated. The cellulose fiber foams have a low density 33 66 kg m3 and can inhibit microbial growth.

Cellulose fiber based insulation foams made of bleached chemi thermo mechanical pulp ctmp have been investigated. Cellulose fiber based fungal and water resistant insulation materials. Two highly valuable features for insulating packaging materials especially in combination with stability in water. The surface morphology of the foams and the distribution of the deposited particles from the extractives were observed by scanning electron microscopy sem.
