Selection of Resin Types for Fiberglass Grating

The main raw materials for producing fiberglass grating include resin, fiberglass, and filler powder, each of which consists of various types. Below, we will focus on introducing three commonly used types of resin for fiberglass grating: ortho-type, iso-type, and vinyl-type. The price is proportional to the corrosion resistance, so it is important to select the most economical type of resin based on the corrosive medium in the usage environment by consulting performance descriptions and corrosion resistance tables. A. Ortho-type: It has ordinary corrosion resistance, can withstand atmospheric aging, seawater corrosion, etc., and has a long-term usage temperature of -50 to 60°C. B. Iso-type (Municipal use): It has excellent corrosion resistance and can...

Analysis of the Characteristics of BWFRP Fiber Wound Pultruded Cable Protection Tubes

BWFRP fiber-wound pultruded cable protection pipes are a new type of casing material, consisting of an inner textile layer, a middle layer, and an outer woven layer, formed through the pultrusion process. The inner and outer woven layers, designed with different weaving angles, combined with the longitudinal and circumferential composite middle layer, together create an ideal composite material product. This new type of cable pipe product has advantages that traditional pipe materials cannot compare to and is widely used in municipal power pipeline networks and communication power pipeline networks. 1. High ring stiffness: Due to the weaving angle generally being greater than 90°, the circumferential stiffness is significantly improved compared to traditional pipe materials. 2. Strong impact resistance: The fiber-wound pultruded cable pipes exhibit excellent impact resistance in all directions.

Analysis of the Development, Applications, and Advantages of Fiberglass Pipes

With the acceleration of urbanization in China, various levels of government are increasing their investment in urban infrastructure year by year to balance and protect population, resources, and the environment. In conjunction with the needs of advanced scientific technology, the variety and specifications of pipes and fittings are continuously enriched, production is steadily increasing, and quality is constantly improving. In particular, the development of plastic pipes has accelerated, making them a current investment hotspot. Fiberglass pipes are one of these. Currently, fiberglass pipes have been widely applied in industries such as petroleum, electricity, chemicals, papermaking, urban water supply and drainage, factory wastewater treatment, seawater desalination, and gas transportation. Here are some excellent characteristics of fiberglass pipes: 1. Aging resistance.

Acceptance of fiberglass reinforced plastic (FRP) pipes

Fiberglass reinforced sand pipes are widely accepted by users due to their excellent chemical corrosion resistance, lightweight and high strength, non-scaling properties, strong seismic resistance, longer service life compared to ordinary steel pipes, lower overall cost, quick installation, and safety reliability. Fiberglass pipes are used in industries such as petroleum, chemical engineering, and drainage. The production of fiberglass pipes in our country is developing rapidly, with increasing quantities year by year, and the application range and sectors are also expanding. When we receive fiberglass pipes, we cannot always guarantee that they are qualified. Therefore, we should inspect the received fiberglass pipes to avoid damage during use.

Analysis of Factors Affecting the Performance of Fiberglass Reinforced Plastic Grating

With the increasing market demand, the performance issues of fiberglass grating have become a major concern for people. So, what are the factors affecting the performance of fiberglass grating? Let's take a look: 1. Ultraviolet (UV) - Do not use fiberglass grating panels without UV protection in direct sunlight environments. 2. Heat - The temperature of fiberglass grating panels in metal pipes or wire ducts can be very high, and many polymer materials will have a reduced lifespan at such temperatures. 3. Water - The moisture in the local area of twisted pair fiberglass grating panels can increase the capacitance of the panels, thereby reducing impedance and causing near-end crosstalk issues.

Introduction to the Characteristics of FRP Cable Ducts

The fiberglass cable conduit is suitable for the protective conduits of power and communication cables laid in various environments. It is especially effective in special environments such as when cables pass through traffic intersections and cross rivers or bridges, showcasing its advantages of easy construction and high strength. It is widely used in the construction of infrastructure in fields such as power, communications, transportation, and civil aviation airports. So, what excellent characteristics does the fiberglass cable conduit have? Here are some specific introductions: 1. Good electrical insulation performance: The fiberglass cable conduit is made of non-magnetic material, which has no eddy current loss and electrical corrosion, thus saving energy and is suitable for single-core cable laying; it has a large current-carrying capacity and low thermal resistance, ensuring the normal operation of the cables.

Analysis of the Causes of Uneven Surfaces in Fiberglass Grating

Fiberglass grating is a type of sheet material made from fiberglass as a reinforcing material, with unsaturated polyester resin as the matrix, processed through special composite techniques to create a board with many voids. Fiberglass grating can be used as a structural material for flooring, trench covers, platforms, ship decks, stairs, walkways, and other applications in corrosive environments. When purchasing fiberglass grating, we can assess the overall quality of the grating board by observing factors such as color, fiber layer distribution, and surface flatness. A dull color may be due to the raw material configuration, while uneven fiber layer distribution may indicate issues with the operational technique.

The emergence and development of fiberglass septic tanks.

Traditional septic tanks are mainly made of brick and concrete structures, and there are also reinforced concrete structures. However, the manufacturing process is relatively simple, lacking technical content, making them prone to leakage and blockage, with poor water treatment effects. This leads to pollution of the surrounding environment and increases the burden on downstream sewage treatment plants. Additionally, the construction process is complex and time-consuming, failing to meet the requirements of environmental protection departments and construction parties. Therefore, the market urgently needs a more suitable and perfect product. Thus, fiberglass septic tanks have emerged. Due to the special nature of the raw materials, fiberglass septic tanks are lightweight, high-strength, non-corrosive, leak-proof, and have outstanding water treatment effects. They are also easy to install; simply digging a pit for burial is sufficient, addressing the shortcomings of traditional septic tanks.
