Why choose fiberglass reinforcement for fiberglass?
Among reinforcement materials, fiberglass fabric is still the most commonly used reinforcement material in the fiberglass industry today. Usually, they are the cheapest among reinforcement materials and are easy to handle. When used in combination with resin, it can provide composite components with excellent strength, low weight, and excellent appearance.
Main defects and countermeasures of RTM products
The quality of the composite depends mainly on the following characteristic porosity: the content of bubbles or voids in the composite must be lower than the value allowed by the structural design. Compaction level: resin content, fiber volume content and related distribution gradients. Curing degree: Formation of polymer resins and their structures. Fiber Direction: Meet the design requirements. Interface bonding: degree of bonding between resin and fiber. Improper die design, low manufacturing quality of preform and unreasonable selection of process parame
Is epoxy resin heat-resistant?The answer to this question is yes
The use of epoxy resin has become very popular, and you can use it in various ways. This includes small projects ranging from jewelry and various art projects to larger industrial applications such as flooring. You also have many different manufacturers and various products, so it may be difficult to know which one to choose from. This is especially true if you are looking for heat-resistant epoxy resin.
Causes and solutions of mold gel coat cracking (delamination)
As shown in the above figure, there is a problem of adhesive coat cracking at the corner of the fiberglass mold. After zooming in on the local location, it is as follows:
The public discussion on the properties of several types of glass fibers made by China Fiberglass Industry Association is hereby reproduced, hoping to be helpful to all customers and colleagues. The full text is as follows: Recently, the secretariat of the Association received consultations from some composite material manufacturers about the performance defects and use hazards of clay glass fibers. With the structural reform of the supply side of the downstream industry and the upgrading of the demand for fiber raw materials in the transformation and devel
The main types and functions of common flame retardants
Flame retardants are functional additives that endow flammable polymers with flame retardancy. They are mainly designed for the flame retardancy of polymer materials. Gas asphyxiation, etc. Most flame retardants achieve the purpose of flame retardancy through the joint action of several mechanisms. endothermic effect The heat released by any combustion in a short period of time is limited. If a part of the heat released by the fire source can be absorbed in a short period of time, the temperature of the flame will decrease, radiate to the combus
Causes of foaming of epoxy resin glue and methods of eliminating bubbles
Causes of bubbles produced in the stirring process: The reason why bubbles are produced in the mixing process of epoxy resin glue is firstly the bubbles caused by the gases brought into the mixing process, and the "cavitation effect" caused by the liquid with too fast stirring speed. However, there are two kinds of bubbles visible to the naked eye and invisible ones. Using vacuum defoaming can only eliminate the bubbles visible to the naked eye, which is not good for removing the tiny bubbles invisible to the huma
Introduction and Main Characteristics of Squeezed Grille
The extruded fiberglass grille has most of the characteristics of the molded fiberglass grille. But there are also significant differences, the most important of which is the high glass fiber content (65% -70%) in the direction of the load-bearing strip, making it more advantageous to use it in large spans compared to molded fiberglass gratings. This will reduce the foundation support and reduce engineering costs. Chemical resistance Select excellent ortho benzene, meta benzene, vinyl resins, and extruded fiberglass gratings with surface felt, which have
Introduction and Progress of Phenolic Extrusion Molding Process
Phenolic resin has significant characteristics such as flame resistance, low smoke release, and low content of toxic gases, making it widely used in various fire and flame retardant applications. However, how to use phenolic resin in the pultrusion molding process has been a process technology issue that has attracted widespread attention from the domestic and foreign fiberglass industry in the past decade. Here is a brief introduction to the latest developments in phenolic extrusion technology. In theory, the pultrusion molding process is relatively simple. The types of reinfor
Introduction of SMC/BMC molding raw materials
Molding is widely used in the following fields: Electrical: insulator, switch box, electrical equipment shell, insulation tools, wiring board, etc. , railway: vehicle window frame, toilet components, seats, table top, carriage wall and roof, etc. · Construction: water tanks, bath supplies, door panels, purification tanks, construction templates, etc. · Sanitary Ware: bathtubs, integrated bathroom equipment, one-piece shaped sink, etc. · and other industrial and agricultural fields.
Application of modified unsaturated polyester in FRP
Unsaturated polyester resin is one of the main varieties of thermosetting resin. Pure unsaturated polyvinyl acetate resin becomes thermosetting material after curing, and its mechanical strength is low, which is difficult to meet the requirements of most application fields. Generally, glass fiber is used to strengthen it to become a composite material. Unsaturated polyvinyl acetate resin is an important variety in the development of modern plastic industry, mainly divided into reinforced and non-reinforced series, which can be widely used in many fields such as industry, agriculture, transport
Why is NPEL-128 epoxy resin popular?
Epoxy resin is a commonly used chemical coating, with excellent corrosion resistance and excellent impact resistance, which is welcomed by various industries. Especially the 128 epoxy resin is highly praised. NPEL-128 epoxy resin is a special liquid bisphenol epoxy resin with excellent properties such as green environmental protection, good viscosity stability, structural stability, antibacterial and mildew resistance, water and moisture resistance, high temperature and wear resistance. It can be used in industrial coatings, vehicle coatings, architectural coatings,
Copper, zinc and nickel smelting processes mainly include roasting flue gas acid-making section, leaching section, electrolytic liquid purification section and back-end tail gas purification and environmental protection section, which belong to the area with serious corrosion. It is necessary to carry out corrosion protection for buildings (structures) such as floors, walls and roof surfaces, steel structures, tanks, etc. of the workshops in each operation section. At the same time, a large number of equipment and pipelines are also made of glass fiber reinforced plastics with high light
In the field of industrial anticorrosion, the elite soldier - FRP FRP material
