Biocidal Natural Building Material
A biocidal natural building material is a natural building material which has biocidal properties. The biocidal properties of biocidal natural building materials are inherent to the material, rather than being supplemented afterwards. This makes that the material is long lasting and inexpensive, as no additional processing needs to be done. Examples * core wood soaked with plant saps: e.g. core wood soaked with the biocidal plant saps from Pinus canariensis (natural durability: 150 years) * several tropical (hard)wood species * resins and plant juices as latex Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well.

Natural Building Material
Building material is material used for construction. Many naturally occurring substances, such as clay, rocks, sand, wood, and even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, insulation, plumbing, and roofing work. They provide the make-up of habitats and structures including homes. The total cost of building materials In history, there are trends in building materials from being natural to becoming more man-made and composite; biodegradable to imperishable; indigenous (local) to being transported globally; repairable to disposable; chosen for increased levels of fire-safety, and improved seismic resistance. These trends tend to increase the ''initial'' and ''lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biocide
A biocide is defined in the European legislation as a chemical substance or microorganism intended to destroy, deter, render harmless, or exert a controlling effect on any harmful organism. The US Environmental Protection Agency (EPA) uses a slightly different definition for biocides as "a diverse group of poisonous substances including preservatives, insecticides, disinfectants, and pesticides used for the control of organisms that are harmful to human or animal health or that cause damage to natural or manufactured products". When compared, the two definitions roughly imply the same, although the US EPA definition includes plant protection products and some veterinary medicines. The terms "biocides" and " pesticides" are regularly interchanged, and often confused with "plant protection products". To clarify this, pesticides include both biocides and plant protection products, where the former refers to substances for non-food and feed purposes and the latter refers to substances ...

Pinus Canariensis
''Pinus canariensis'', the Canary Island pine, is a species of gymnosperm in the conifer family Pinaceae. It is a large, evergreen tree, native and endemic to the outer Canary Islands of the Atlantic Ocean. Description ''Pinus canariensis'' is a large evergreen tree, growing to tall and diameter at breast height, exceptionally up to tall and diameter. The green to yellow-green leaves are needle-like, in bundles of three, long, with finely toothed margins and often drooping. A characteristic of the species is the occurrence of glaucous (bluish-green) epicormic shoots growing from the lower trunk, but in its natural area this only occurs as a consequence of fire or other damage. The cones are long, wide, glossy chestnut-brown in colour and frequently remaining closed for several years (serotinous cones). Its closest relatives are the chir pine (''P. roxburghii'') from the Himalayas, the Mediterranean pines '' P. pinea'', '' P. halepensis'', '' P. pinast ...

Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non- vulcanized rubber. Such is the case in products like latex gloves, latex ...

Latex Allergy
Latex allergy is a medical term encompassing a range of allergic reactions to the proteins present in natural rubber latex. It generally develops after repeated exposure to products containing natural rubber latex. When latex-containing medical devices or supplies come in contact with mucous membranes, the membranes may absorb latex proteins. In some susceptible people, the immune system produces antibodies that react immunologically with these antigenic proteins. Many items contain or are made from natural rubber, including shoe soles, pen grips, hot water bottles, elastic bands, rubber gloves, condoms, baby-bottle nipples, and balloons; consequently, there are many possible routes of exposure that may trigger a reaction. People with latex allergies may also have or develop allergic reactions to some fruits, such as bananas. Signs and symptoms Allergic reactions to latex range from Type I hypersensitivity, the most serious form of reaction, to Type IV hypersensitivity. R ...
