Generally, raw materials employed in the manufacture of roofing underlying materials are asphalt, cellulose base (organic), fiberglass substrate, and polymers (including polyethylene and polypropylene). Based on product type, the roofing underlying materials market has been segmented into asphalt-saturated felt, rubberized asphalt, and non-bitumen synthetic. Asphalt-saturated felt and rubberized asphalt are asphalt based; however, rubberized asphalt derives its elastic properties from rubber-like materials (mostly polymers) added during the manufacturing process. Roofing underlying materials are commonly used in applications such as residential construction, non-residential construction, and commercial constructions such as buildings, hotels, offices, public outlets, and educational institutes.

Non-bitumen synthetic roofing underlying materials segment was the largest product segment of the roofing underlying materials market, constituting more than 35% share in terms of volume in 2015. Synthetic underlying materials are preferred over asphalt-based underlying materials, as the synthetic materials are easier to install and can withstand harsh environments better than the asphalt-based materials. Synthetic underlying materials also provide better resistance to moisture, rain, vapor, UV radiation, and fungal damage. This segment is also estimated to be the fastest growing product segment of the roofing underlying materials market during the forecast period.

Application synthetic asphalt in road surfaces

Chemical and physical properties synthetic asphalt and asphalt modified synthetic asphalt (gilsonite).

Synthetic asphalt (gilsonite)e consists of high oligomericheskih polar polycyclic hydrocarbons. Due to the unique structure of the asphaltenes, synthetic asphalt (gilsonite) may significantly improve the quality of the bituminous binder even when adding a very small amount. Being a natural asphalt, synthetic asphalt (gilsonite) easily dissolved in the asphalt to form a homogenous fully sustainable binder. However, for this to happen, it is necessary that the product has been introduced at temperatures above the softening point synthetic asphalt (gilsonite) at 10-20 ° C (18-36 ° F), and to provide intensive stirring mixture to prevent settling synthetic asphalt (gilsonite) before it dissolves. For more information on this topic is presented in our brochure "Recycling gilsonite the asphalt."

Composition and performance asphalts modified synthetic asphalt (gilsonite)

Synthetic asphalt (gilsonite) modified asphalts tend to exhibit significantly better high temperature properties. Due to the fact that the addition of synthetic asphalt (gilsonite) changes the ratio of oil and asphaltenes, it may adversely affect the properties of the low and medium temperatures. However, in accordance with data obtained in our study, when using a conventional asphalt modifier 1-4% natural balance of the various components of asphalt retained.

The degree of viscosity and depth of penetration of the asphalt

As previously mentioned, synthetic asphalt (gilsonite) may significantly improve the high temperature properties of bituminous binders. Synthetic asphalt (gilsonite) increases the softening point by ring and ball Metolit and absolute viscosity and reduces the penetration rates of asphalt binders without impurities and modified asphalt. Consequently, it also increases the high temperature stiffness and reduces the phase angle of the asphalt base.

Training and preparation of hot mix asphalt, modified synthetic asphalt (gilsonite)

To add the synthetic asphalt (gilsonite) - simple. Synthetic asphalt (gilsonite) is added either in hot melt bags or by using a screw conveyor for feeding the mixer synthetic asphalt (gilsonite) or mixing drum installation for hot mix asphalt. This ensures minimal interruption of the production cycle.
Synthetic asphalt (gilsonite) fits well and is fully compatible with other components of the hot mix asphalt, so the use of synthetic asphalt (gilsonite) has virtually no influence on the process of paving, as there is no need for any special equipment.

Biomedical applications of microspheres in drug delivery and bone tissue engineering offer many advantages over other particle geometries.
Microspheres can be made to have a uniform size and shape to enhance their delivery to target sites and to have a large surface area to enable sufficient therapeutic coatings.
However, their manufacture is associated with development and production challenges, especially in large-scale production.
Microspheres can be produced with different materials, including glass-, ceramics-, and polymer-based microspheres, which provides them with varying properties and applications.
Porosity
Porosity is an important consideration in microsphere production, particularly for tissue engineering and drug delivery applications. Porous microspheres enable a greater loading efficiency and improved control over the release of medications, growth factors and other components.
Their large surface area also means they are favorable for cell attachment and proliferation. Other important features to consider during porous microsphere production are interconnected and open porosity and favorable pore size.
Porous microspheres can be made with external and/or internal porosity and with or without interconnectivity for cell attachment and proliferation over the surface area.
Although porous microspheres possess these superior features, non-porous microspheres can be useful for certain applications that require higher mechanical properties such as bone tissue regeneration.
Polymer based microspheres
Polymer-based porous microspheres have been a significant focus of attention due to their potential in controlled drug release, either by degradation of the polymer matrix or through the leaching of drug components from the polymer.
During production, the selection of either synthetic or natural biodegradable carrier matrices for drug delivery is an important consideration. Natural polymers such as collagen and protein undergo enzyme degradation, whereas synthetic polymers degrade by hydrolytic activity.
The synthetic polymer polylactic acid (PLA) is a common polymer used for biomedical applications due to its degradation rate and desirable mechanical properties. Solvent and emulsion-solvent evaporation processes can be used to create microspheres with differing morphologies.
For example, in 1991, S Izumikawa and colleagues reported investigating progesterone drug-loaded poly (l-lactide) (PLLA) microspheres prepared using a solvent evaporation process.
They found that removing volatile solvent at atmospheric pressure formed PLA microspheres that were crystalline in structure, whereas at lowered pressures, the removal of the solvent led to the formation of microspheres with amorphous polymer matrices.
The researcher’s study suggested that the crystalline microspheres with rough surfaces and large surface areas enabled rapid drug release compared to the smooth, amorphous structures.
Protein microspheres are widely used as natural polymer microspheres in drug delivery due to their selective uptake by specific cells, their high biological activity and the numerous sites they provide for drug components to attach to. They can also be combined with numerous different drugs to produce derivatives with specific pharmacological properties.
Glass and ceramic based microspheres
Glass and ceramic-based spheres are generally studied for tissue regeneration, radionuclide therapy and applications in dentistry or orthopedics.
Glass based microspheres
The three types of glass-based microspheres are generally borate, silicate and phosphate-based.
Borate-based glass spheres, have become particularly attractive as delivery vehicles of biodegradable radiation, especially in the treatment of arthritis, owing to their uniform size and shape. These spheres were often considered ideal for radiation synovectomy (the removal of the synovium membrane that lines a joint).
The use of silicate-based bioglass, glass–ceramics microspheres and silica nanospheresin biomedical applications has also been investigated. A glass-ceramic phase is a material that has one or more crystal phases placed within a glassy matrix.
Various studies have concentrated on the generation of silicate-based microspheres, but achieving the correct size distribution and surface texture as well as avoiding aggregation has proved challenging.
One method used to manufacture microspheres is the sol-gel method via the Stöber process which was investigated by researchers Hui Liu and colleagues in 2012. Hydrolysing and polycondensing tetraethoxysilane ethanol solution (TEOS) has previously produced monodispersed silica microspheres 0.3µm in size.
