As you may know, ozone is a gas. Ozone molecules have three oxygen atoms (O3), unlike the oxygen in the air that gives life to the planet (O2). Ozone is powerful because the extra oxygen atom can easily escape and attach to other substances. This highly reactive quality can potentially alter the chemical composition of some substances in the air and affect our cells if we breathe it in.

When you hear the term “ozone” you may think of the ozone layer, which protects all life from the dangerous UV radiation of the sun. This is the “good” ozone that is present in the stratosphere. But the ozone at ground level is “bad” since it is hazardous to health and is classified as an air pollutant by the EPA. Ozone at the ground level is created in nature by the interaction of sunlight with certain chemicals that are released to the environment, including vehicle and industrial plant emissions. It is also created when lightning strikes, which is why you may be able to smell ozone after a storm. Ozone, whether pure or mixed with other chemicals, can be harmful to health.
Yes, whether ozone is mixed with other chemicals or in pure form, it can be harmful to your respiratory system when inhaled.

Since the early 20th century, health professionals have warned about the dangers of ozone. Just as it reacts with substances outside of the body, it can react with the living tissue within your body. This means that ozone can cause a variety of health problems, like coughing and airway inflammation. It can also reduce lung function and harm lung tissue. Certain groups like children, people with asthma, and older adults are especially vulnerable.

You may have heard of the Clean Air Act. Under this federal law, the Environmental Protection Agency (EPA) sets standards for outdoor air quality to protect public health. There are six air pollutants that the agency has set standards for, and ozone is one of them. If ozone is dangerous enough for the EPA to monitor outdoor levels, then it is all the more dangerous for ozone generators to release pure ozone into your home.

For context, the US Food & Drug Administration (FDA) requires that indoor medical devices can only produce a maximum of 50 ppb (parts per billion) of ozone. The National Institute of Occupational Safety and Health (NIOSH) recommends that indoor ozone levels should not be greater than 100 ppb.

This study deals with the investigation of flexural stiffness and transverse shear rigidity in the direction of corrugation of the integrated and non-integrated corrugated core sandwich panels with the rectangular core. The non-integrated sandwich panels were reinforced with conventional 2-D fabrics in which resin provides the bond between core and skins. The integrated sandwich panels were reinforced with 3-D weft knitted fabrics in which bonding of the core wall to skins was carried out by combined efforts of knitted loop and resin. Using weft knitting technical capabilities, samples of the integrated and non-integrated structures were manufactured with the uppermost degree of resemblance in terms of geometry and mass. Flexural stiffness and transverse shear rigidity of the structures based on the known and unknown facing modulus of ASTM D7250 standard and Nordstrand–Carlsson methods were calculated. The estimated elastic constants based on unknown facing modulus and the Nordstrand–Carlsson methods were found to be highly compatible. However, the unknown facing modulus method is prone to disclose the statistical significant differences between the elastic constants of the structures with fewer tests. Regarding the unknown facing modulus method, it was found that the flexural stiffness and transverse shear rigidity of the non-integrated structure in the direction of corrugation were higher than those of the integrated structure. Results also indicated that the load-carrying capacity in the direction of corrugation was significantly higher in case of the non-integrated rectangular core structure compared with that of the integrated structure.Get more news about Bh-sandwich Panel Series,you can vist our website!

Sandwich panels are composed of a thick and low-density core which is sandwiched by two thin and stiff skins or face sheets [1, 2]. High specific flexural stiffness and strength are among the main features of sandwich panels. The core can be composed of miscellaneous materials such as foam, honeycomb, and corrugated sheets. Corrugated cores in comparison with foam or honeycomb are superior as far as factors such as shear strength in the transverse direction of corrugation, strength to weight ratio, structural integrity, and fluid storage capacity are concerned. The core geometry in the corrugated core sandwich panels is more than often trapezoidal (hat-type), rectangular, triangular, circular, and sinusoidal [3, 4]. An additional bonding operation using adhesive is used in the production of the laminated composite where core and skins have to be prepared separately. Poor mechanical performance of adhesive, complexity associated with predication, and determination of joints strength as well as small contact surface area between the core and the skins are among the disadvantages associated with the adhesively bonded corrugated core sandwich panels. The stated disadvantages may lead to the poor mechanical performance of the resultant composite structures or their delamination [5,6,7,8,9,10]. Taghizadeh et al. [11] experimental investigation revealed that the delamination of skin–core is the principle damage mechanism that can occur in corrugated core sandwich panel composites. Blingardi et al. [8] investigated the mechanical properties of the foam core sandwich panel composites using 4-point bending tests. It was found that skin–core delamination due to shear failure is the principle cause of structural failure of the sample. It was also established that the addition of a resin network perpendicular to the skins enhances flexural strength and impact resistance of the structure. Zhang et al. [7] investigated the effect of corrugation angle, core-sheet thickness, and core to skins bond length on the flexural strength of the corrugated core sandwich panel composites in the transverse direction of corrugation. It was found that not only failure occurs in the bond length but also specific flexural strength at a given corrugation angle and core-sheet thickness is reduced due to an increase in the bond length.

When 3-D fabrics are used as reinforcement in composites, the presence of Z-yarn along the thickness eliminates the poor bonding of the laminated layers [5, 12]. The integrated composites reinforced with 3-D fabrics have higher inter-laminar shear load-carrying capacity than the non-integrated version. The integrated composites possess higher delamination resistance. Additionally, strength along the thickness in the integrated structures is higher than those of the non-integrated version. The mechanical and thermal stability of the integrated structures along principle directions is unique [5, 13]. Karahan et al. [14] compared conventional foam core sandwich panel composites with 3-D integrated sandwich panel composites in which the connection of the skins to each other was made using pile yarns. It was concluded that the use of pile yarns significantly improves the compression behavior of the 3-D integrated sandwiched panel. Ivanov et al. [15] and Lomov et al. [16] compared conventional non-integrated 2-D woven laminated composite with integrated non-crimp 3-D orthogonal woven composite. It was found that as far as in-plane strength, failure strain, and damage initiation thresholds were concerned, the integrated composite was significantly superior in comparison with the non-integrated.

There are lots of different types of boxes out there. Who knew that there were hundreds of variations of corrugated cardboard boxes?
Some of the terminology used to describe boxes is dense and downright confusing. What does all of this mean?
First, rest assured that you don’t need to memorize any complex codes or charts. You just need to understand enough to find the cardboard boxes that suit your business.

In this post, we’ll do a brief overview of the different types of corrugated cardboard boxes so you are prepared to make the right choice.

What is fluting?
In cardboard boxes, fluting is formed by the arched shapes (flutes) that create space between layers of cardboard. Fluting helps make cardboard boxes durable and protect any contents inside.

Flutes are available in different sizes (measured by flute height, which dictates how thick a cardboard box’s walls are) and densities (measured by flute grammage, which shows how dense the paper in a box’s walls is ).
Single wall cardboard boxes have walls that contain one layer of fluting. In other words, each box is made up of three layers – an outer layer of paper + a single layer of flute + an outer layer of paper. These boxes are lightweight and suitable for products of average weight and fragility. DS Smith’s single wall boxes have a thickness of 3 mm and can ship and store packages with a maximum weight of 10 Kg (or 5 Kg if sent on pallets).

Single wall boxes can come in all kinds of shapes and sizes. Discover the large range in our online shop to find the one that fits your products perfectly:

Double wall cardboard boxes feature walls with two layers of fluting. Each double wall box is made up of five layers – an outer layer of paper + a layer of flute + a layer of paper + another layer of flute + an outer layer of paper. These boxes are stronger and more durable than single wall boxes, so they are more suited to heavier items or products that need additional protection and cushioning. DS Smith’s double wall boxes have a thickness of 5mm, and can support up a weight of up to 20 Kg (or 10 Kg if shipped on pallets).

Maximum weight recommendations for each box type may vary, depending on the type of product being shipped, the void fill or protective material included and the shipping method used.

Don’t take any chances with your products. Use DISCS ­– Drop, Impact, Shock, Crush, Shake – DS Smith’s industry leading distribution testing process, and get tailored packaging recommendations that fit your distribution model. DISCS will put your products through real-life shipping scenarios to determine what packaging will offer the best protection.

After being exposed to damage risks – being carried and loaded onto different modes of transport, possibly dropped and bumped along the way – you will be sure your package is sturdy enough to survive the journey to your customer.
