Jelaskeun bédana antara papan serat gelas epoxy sareng papan PTFE sacara rinci

Dinten ayeuna, abdi hoyong bagikeun sareng anjeun bédana antara papan serat kaca epoxy sareng papan PTFE, teras hayu urang tingali babarengan.

Anu mimiti, urang peryogi kauninga naon papan serat gelas epoxy sareng papan PTFE.

PTFE plates are divided into two types: molded plates and turned plates. The molded plates are made of polytetrafluoroethylene resin by molding at room temperature, then sintered and cooled. The turning board is made of PTFE resin by pressing, sintering, and peeling. There are two types of PTFE plates: molded plates and turned plates. The molded plates are made of polytetrafluoroethylene resin by molding at room temperature, and then sintered and cooled. The turning board is made of PTFE resin by pressing, sintering, and peeling. High temperature resistance up to 250℃, low temperature resistance -196℃, corrosion resistance, weather resistance, high lubrication, non-adhesion and other characteristics. Except for the molten alkali metal, the PTFE plate is hardly corroded by any chemical reagents. For example, in concentrated sulfuric acid, nitric acid, hydrochloric acid, or even boiled in aqua regia, its weight and performance are unchanged, and it is almost insoluble in all solvents.

Epoxy glass fiber board is also called epoxy glass fiber board, epoxy phenolic laminated glass cloth board, epoxy resin refers to the organic polymer compound containing two or more epoxy groups in the molecule. The relative molecular mass of is not high. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, in the middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can undergo cross-linking reactions with various types of curing agents to form insoluble and infusible polymers with a three-way network structure.

The PTFE board is made of polytetrafluoroethylene resin through a special process such as molding, hydraulic pressure, turning, etc. Its performance can withstand high temperatures of 260 degrees. The epoxy glass fiber board is made of glass fiber impregnated with epoxy resin glue and curing agent. , The temperature resistance is about 100 degrees, the PTFE board can withstand any acid and alkali, and the epoxy is afraid of strong acid. From the perspective of plastic classification, the former belongs to the thermoplastic plastic, and the latter belongs to the thermosetting plastic. The epoxy glass fiber board has high strength at room temperature.
