Measurement of the unwanted washboarding on corrugated cardboard is done to check that it does not exceed an acceptable level.

• Washboarding is a regular line pattern that can occur when the liner is glued on the fluting when making corrugated cardboard.
• Corrugated cardboard is the most common material when manufacturing packaging boxes because it has good shock-absorbing properties that protect the product.
• In addition to measurement, we can also sell software license for the measurement method OptiTopo Expert with washboarding toolbox. This software is based on the use of the instrument L&W OptiTopo sold by ABB (formerly Lorentzsen & Wettre).

The measurement gives:

• A quality measure of how large the washboarding effect is.
• The liner's fine-scale surface roughness and craters that often correlate with print quality after the corrugated board surface is printed.
• Illustrative images of the washboarding effect that make it easier to visually compare different samples and use the results in reports and presentations.

Traditionally, rod coating has been used to test surface adhesives and coatings for spreads on graphic paper. But the method has also proven to be valuable for testing coating of new chemical solutions. The method has therefore had a renaissance and is now used in several new application experiments, including nanocellulose.

The effects of coating with viscose, nanocellulose and lye on different test surfaces are some examples of coating solutions that can be used. These solutions are applied to the sample using a rod. Different rods are available, ranging from smooth to grooved for different amounts of toppings and solutions. After coating, the sample is dried with, for example, IR dryer, but several drying methods are available. More layers can be applied or the sample can be tested directly in lab.

Various surface adhesives and creams can be boiled and prepared in jet boilers. Samples in A4 format are usually used for coating, but even smaller formats can be coated. Stick coating is a fast method that does not require large amounts of material. After coating, there are also many different options for testing the coated surface, such as contact angle, surface roughness and friction. A good complement to other analyzes of the surface are Cobb 60 and Cobb Unger. The strength properties of the test as well as air permeability and air permeability are examples of other interesting tests that can be performed.

The quality of the wood chips is critical to the production of pulp, and at RISE we offer several different analyses to ensure the quality of the wood chips. By carefully examining and evaluating various properties, we can identify any defects or deviations that may affect the production process and the quality of the resulting pulp.

We analyse several key parameters in wood chips, including bark content, moisture content, bulk density and dimensions, to ensure high quality pulp production:

• Bark content: Affects pulp quality by introducing impurities; measurement indicates how well the chips have been cleaned.
• Bulk Density: Reflects the packing density of the chips and affects flowability and absorption of cooking chemicals.
• Size and thickness: Consistent size distribution and optimum thickness are essential for effective impregnation, chemical absorption and uniform cooking quality.

Together, these parameters optimise the process and improve pulp quality and uniformity.

• Dry content SCAN-CM 39:94 Determination of bark content in wood chips for the production of chemical and mechanical pulps. It is applicable for the determination of wood grade chips, preferably in conjunction with the method of chip size distribution described in SCAN-CM 40.
• Size distribution SCAN-CM 40:01 Classification of wood chips intended for the production of chemical and mechanical pulps and is applicable in determining the quality of wood chips in terms of chip size and fineness.
• Bark content SCAN-CM 42:06 Determination of bark content in wood chips for the production of chemical and mechanical masses. 
  Dry-Crude Density or Bulk Density SCAN-CM 46:92 Method for determining the bulk density of wood chips intended for the production of chemical or mechanical pulps. It is also possible to measure the bulk volume of wood chips, i.e. the volume of loosely packed chips.
• Thickness and thickness distribution SCAN-CM 47:92 The method is applicable in determining the quality of wood chips. 
  Length and length distribution, width and width distribution SCAN-CM 48:01 Determination of mean length and length distribution of wood chips intended for the production of chemical or mechanical pulps (accepted chips).
• Wood content in bark fraction SCAN-CM 53:94 Determination of the wood content of the bark fraction from a bark drum or from other debarking machinery. The method is applicable in the determination of wood losses in the debarking process. The total timber loss also includes breakage.
• Dry-raw density SCAN-CM 43:95 Determination of the basic density of wood chips for production of chemical and mechanical pulps.

• Metals
• Extractives
• Carbohydrates
• Ash content

Our aim is to ensure that your results are delivered on time, taking into account the specific requirements of your project. Thank you for your understanding and patience as we work to provide you with the best possible service.

It is important that the materials on the market are free of hazardous and regulated substances. Chemical analysis is a way to gain control over the products' chemical content.

Society and consumers place great demands on companies and their products. The legislation also means that you as an actor must have complete information and control over which chemicals your products contain. It is especially important with products for children and goods that come into contact with the skin, such as clothes and accessories.

We help you interpret chemical legal requirements and restrictions that apply to goods made of textile materials and plastics and that are linked to, for example, REACH and POPs. We suggest which analyzes you need to do based on legal requirements, but also other requirements specifications such as eco-labels or procurement requirements.
