What are the use conditions of epoxy glass fiber board
Epoxy glass fiber board is also epoxy phenolic laminated glass cloth board. Epoxy resin generally refers to organic polymer compounds containing two or more epoxy groups in the molecule. Except for a few, their relative molecular masses are all different. 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 epoxy glass fiber board of this product is made by heating and pressing with epoxy resin. It has high mechanical performance at medium temperature and stable electrical performance under high humidity. It is suitable for high-insulation structural parts for machinery, electrical appliances and electronics, with high mechanical and dielectric properties, good heat resistance and moisture resistance, and heat resistance class F (155 degrees).
There are many types of epoxy glass fiber board, the common ones are 3240, G11, G10, FR-4, etc. They have the same general performance, are all high-temperature insulation materials, and the details are slightly different. For example, the use temperature of FR-4 is Around 130°C, while the use temperature of G11 can reach 180°C. So how is the performance? In this article, I will talk about the use conditions of epoxy glass fiber board.
1. The operating temperature of epoxy glass fiber board is 120 degrees Celsius. It can be used in an environment of 130 degrees Celsius in a short time. If it exceeds this temperature, it will warp, crack and become unusable.
2. دا د 1000V/MIL د ډایالټریک ځواک او د 65 kV د ماتولو ولتاژ سره ښه بریښنایی ځانګړتیاوې لري، کوم چې کولی شي په لوړ ولتاژ او اوسني چاپیریال کې په دوامداره توګه کار وکړي.
3. دا قوي ماشیني وړتیا، ښه میخانیکي وړتیا، د 303 MPa فشاري ځواک، د 269 MPa تناسلي ځواک، د 455 MPa د موړ ځواک، او د 130 MPa د شین ځواک لري. دا کولی شي د بهرنۍ نړۍ قوي اغیزو سره مقاومت وکړي او ښه سختۍ لري.
4. کیمیاوي ملکیتونه هم ښه دي، د یوې ټاکلې درجې د کنډک مقاومت سره.
5. دا غیر شعاع retardant، غیر برومین، د EU معیارونو سره سم، د چاپیریال سره دوستانه، او چاپیریال به ککړ نه کړي. دا په بهر کې ډیر کارول کیږي.
دا له پورته څخه لیدل کیدی شي چې د epoxy شیشې فایبر بورډ فعالیت خورا ښه دی. دا د شیشې فایبر شیټ څخه جوړ شوی چې د دوامداره فلامینټونو سره اوبدل شوي چې د epoxy رال سره تړل شوي. دا د پیرودونکو اړتیاو سره سم مستقیم تنظیم کیدی شي. که پروسس شوي برخې پروسس شوي وي، مهرباني وکړئ د انځورونو پروسس ته مراجعه وکړئ.
