WOOD TREATMENT

WOOD TREATMENT

Why Wood?

Wood is an organic matter and is susceptible to microbial attack:

Biocides

Biocides are chemical or microbiological substances, that are intended to neutralize harmful organisms in the nonagricultural sector. Among others, these harmful organisms may include fungi, bacteria, yeasts and algae. Microbial activity can cause discoloration, break down of emulsions, gelling or thinning, shifts in pH, bad odor and even gassing. On surfaces visible growth of fungi, bacteria and algae can occur. Biocides provide protection for health and protection of products. Therefore, biocides play a significant role in the maintenance of health and hygiene standards.

Bacteria only attack wood when it is extremely wet e.g. when stored in log ponds, buried in the soil or used in cooling towers. The most commonly found bacteria are:
1. Escherichia spp.
2. Pseudomonas spp.
3. Staphylococcus spp.

Fungi

Fungi attack wood under damp conditions. This decay often originates in wood, which is in contact with the ground or where wood becomes damp. Two groups of fungi are found growing on timber; wood destroying fungi and wood discolouring fungi.

Wood destroying fungi cause decay of the wood, which results in a loss of strength as the wood, is destroyed. Wood destroying fungi may be further divided into brown, white and soft rots:

Brown rots are recognised by a darkening of the wood under attack. On drying the wood becomes brittle and often cracks. Fungi of this type commonly cause decay in buildings e.g. the dry rot fungus, serpula lacrymans and wet rot fungi, coniophora puteana.

White rots are characterised by a lightening of the attacked wood. Hardwoods are particularly susceptible. Fungi of this type commonly cause decay in external joinery e.g. donkioporia expansa.

Soft rots are characterised by wet wood being softened progressively from the surface. Wood used in water cooling towers or in the ground are prone to these fungi e.g. ascomycetes. Hardwoods are again particularly susceptible.

Wood discolouring fungi cause stains and moulds, which are surface growths that do not reduce the mechanical properties of wood but instead discolour it. In the case where appearance is important, there can be a loss of value. Softwood is more at risk than hardwood. Blue stain and sapstain fungi colonise and penetrate into wood to cause a blue or brown colouration in spots or streaks. Mould fungi can spread on the surface of wetted timber, where they feed on sugars and can cause different colorations e.g. black brown. The most common fungi are:

• Aspergillus spp.
• Aureobasidium spp.
• Trichoderma spp.

Beetles
Wood boring insects are important pests in that they cause much damage in wood in structure and storage. The insects found damaging wood belong to the Cerambycidae, Anobiidae and Curculionidae families. Insects attacking wood in storage belong to the families Lyctidae, Bostrychidae, Platpodidae, Scolytidae and Cerambycidae.

Termites
Termites are a major problem in certain regions of the World such as France, Japan and parts of North America. If there is a termite problem, it normally requires the treatment of the whole building. The main termites found are: Coptotermes lacteus, Coptotermes formosanus, Nasutitermes exitiosus, Reticulitermus lucifugus, Reticulitermus flavipes, Kalotermes flavicollis.

Features of a Wood Preservative

Wood preservatives are used to control the above pests and the ideal wood preservative will have the following features:

• Have sufficient efficacy against wood destroying organisms • Be able to penetrate wood
• Be chemically stable
• Be able to be safely handled
• Be economical to use
• Not weaken the structural strength of the wood
• Not cause significant dimensional changes within the wood.
• Be toxicologically tested and approved
• Insecticide properties may be required

PAM ANIONIC

Anionic Polyacrylamide (APAM)

The PAM products are used in various industrial waste treatments as coagulants  and flocculants. The main fields involve:

Beer industry/pharmaceutical industry/papermaking industry/Mining industry/Petrochemistry industry/Textile printing and Dyeing/Chemical industry/Food processing industry/Waste water (containing oil) treatment industry,etc.

Wastewater treatment is necessary in many kinds of industrial fields, the selection of Polyacrylamide varies according to the type of wastewater, and the treatment process.

In the primary waster treatment(floation or sediment),we use a combination of inorganic additive and flocculant. In some specific cases, We must adjust the PH in order to obtain a better result.

In the last step of dewatering process, the use of one kind of organic flocculent is enough to meet the needs. Most used products are cationic Polyacrylamide. Only in some specials cases, anionic Polyacrylamide are used. The products will be chosen according to each process by technicians.

Jual DINP Plasticizer

Diisononyl phthalate (DINP) is a phthalate used as a plasticizer. DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid.
DINP is a mixture of isomers that have alkyl chains from 7 to 9 carbons long, but the largest portion of the mixture have chains composed of 8-carbon in length (a.k.a. isononyl alcohol).
The European Union has set a maximum specific migration limit from food contact materials of 9 mg/kg food for the sum of diisononyl phthalates anddiisodecyl phthalates.
DINP is almost colourless and odourless oily liquid, free of foreign materials which 0 is slightly soluble in water ( 0.285mg/L at 24 C ) but soluble in alcohols, hexane etc. It is miscible and compatible with all the monomeric plasticizers of PVC compounding.
Around 95% of DINP is used in PVC as a plasticizer. More than half of the remaining 5% is used in the production of polymers other than PVC (e.g.rubbers). The remaining DINP used in non-polymer application including anticorrosion paints, anti-fouling paints, lacquers, inks, adhesives and sealants.
DINP is a monomeric primary plasticizers of medium molecular weight and fine performance. It has been developed to fulfill the need for an economical plasticizer in formulation which require very low volatility and good permanence characteristics. This products is widely used in vinylic compounds including wires, cables and plastisols.
Diisononyl Phthalate (DINP) C6H4(COOC9H19)2, is a clear, colorless, and almost odorless liquid chemical. It is soluble in most organic solvents. DINP is primarily used as a PVC plasticizer. As compared to DOP, the low volatility and better endurability of DINP significantly reduces the fume emissions during the processing procedure and improves its permanence in the final product.

Plasticizer Overview
Plasticizers are polymer additives that serve to increase the polymer’s flexibility, elongation and ease of processing. In other words, they make the polymer more workable. In technical terms, the addition of a plasticizer generally causes a reduction in the cohesive intermolecular forces along polymer chains. The chains can then move more freely relative to one another, hence reducing the stiffness of the polymer.
The use of plasticizers began in the mid 1860s when castor oil was added to Cellulose Nitrate. The most commonly measured physical effects include melt viscosity, elasticity modulus, and the glass transition temperature. Other types of plasticizers have been used through the years, but in the late 1930s, phthalates were introduced because they were believed to be less toxic. The two most common plasticizers used today are di-2-ethylhexyl phthalate (DEHP) or DOP/ DiocthylPhytalate and di-isononyl phthalate (DINP), both of which are generally used in the manufacture of PVC related products.

METHYL SOYATE

Methyl Soyate is an excellent vegetable based solvent used in applications, such as parts cleaning and degreasing, paint and ink removal, and oil spill remediation. It has been marketed in numerous consumer products including hand cleaners, car waxes, and graffiti removers.

Methyl soyate, a biobased solvent made from vegetable base / soybean oil, is an excellent replacement for petrochemical solvents. It offers numerous advantages over  traditional solvents.

Methyl Soyate has important environmental- and safety- related properties, which is an advantage for many industrial applications. It is lower in toxicity than any other solvents, is readily biodegradable, and has a very high flash point and a low level of volatile organic compounds (VOCs). Methyl Soyate is compatible with metals, plastics, most elastomers and other organic solvents.

Safety advantages
• High flash point (greater than 360 degrees F)
• Low VOC levels (<50 g/L )
• Non-ozone-depleting chemical (ODC)
• Non-SARA reportable
• Readily biodegradable
• Potential for reduced waste-disposal costs



Performance advantages
• Can be used to formulate many types of products
• Provides effective solvency with a kauri-butanol (KB) value of 58
• Compatible with other organic solvents

Methyl soyate has a high solvency with a Kauri-butanol (KB) value of 58 and has low toxicity when compared to other common substances. In comparison to most commercial solvents, methyl soyate is safer to handle and store due to its high flashpoint of approximately 360 degrees Fahrenheit and high boiling point of well over 400 degrees Fahrenheit. 

In addition, the Environmental Protection Agency (EPA) does not list methyl soyate as an ozone-depleting chemical (ODC), hazardous air pollutant or volatile organic compound. Methyl soyate has slow evaporation time can be seen as a disadvantage, but in certain applications methyl soyate outperforms other traditional solvents when longer settle times are needed.



Beyond being an ingredient in cleaners and strippers to replace chlorinated or petroleum products, methyl soyate could find increased use as a carrier solvent. Solvents used as carriers and diluents in a number of alkyd coatings and adhesives include methyl ethyl ketone peroxide (MEK), toluene and xylene for coatings and methylene chloride (MeCL) and MEK for adhesives.

Methyl soyate is not limited to replacement of regulated industrial cleaning solvents. Due to its eco-friendly nature, methyl soyate can be used to clean up and recover spilled petroleum products from shorelines and streams. In fact, the EPA has listed a methyl soyate biosolvent on the National Contingency Plan product schedule for oil spills. It is also licensed by the state of California as a shoreline cleaner.


Formulated consumer products ranging from hand cleaners to auto-care to personal care products that utilize methyl soyate are already being produced and marketed. Additionally, expanding utilization of methyl-soyate-based co-solvents with ethyl lactate in products such as Vertec Biosolvent, Vertec Gold solvent, and methyl-soyate-based co-solvents with d-limonene (citrus extract) in products such as CITRU Soy by Bi-O-Kleen Industries, Inc. also show promise. 

Vertec Gold is used in specialty coatings, inks and cleaners and offers increased versatility and high performance. CITRU Soy solvent, cleaner and degreaser are suitable for removing gum, wax, tar, asphalt, graffiti and more. Other new emerging applications for soy-based-solvent products and processes include bioremediation, paper pulp cleaning and highway paving materials that replace asphalt.


Methyl soyate is proving to be a great alternative to chemical-laden cleaners and solvents. Development and commercialization of biobased products are rapidly expanding because of increased government regulations and market demands for safe, healthy and environmentally-friendly alternatives to terpene or petrochemical based solvents and cleaner/degreasers containing butyls. Opportunities to increase the usage of methyl soyate continue to grow.
