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. Он дорои хосиятҳои хуби электрикӣ, бо қувваи диэлектрикии 1000V/MIL ва шиддати шикасти 65 кВ, ки метавонад дар муҳити баландшиддат ва ҷорӣ пайваста кор кунад.

3. Он дорои machinability қавӣ, қобилияти механикии хуб, қувват фишурдасозии аз 303 МПа, қувват tensile аз 269 МПа, қувват мепечонад 455 МПа, ва қуввати буридани 130 МПа. Он метавонад ба таъсири сахти ҷаҳони беруна тоб оварад ва устувории хуб дорад.

4. Хусусиятҳои кимиёвӣ низ хуб буда, дараҷаи муайяни муқовимат ба зангзанӣ доранд.

5. Ин аст, ғайридавлатӣ retardant алангаи, ғайри бром, мутобиқи стандартҳои ИА, экологӣ тоза, ва хоҳад муҳити зист ифлос намекунад. Он бештар дар хориҷа истифода мешавад.

Аз гуфтахои боло дида мешавад, ки кори тахтаи нахи шишагии эпокси хеле хуб аст. Он аз варақи нахи шишагин сохта шудааст, ки бо филаментҳои пайваста бо қатрони эпоксидӣ пайваст карда шудаанд. Он метавонад мустақиман мувофиқи талаботи муштариён фармоиш дода шавад. Агар қисмҳои коркардшуда коркард карда шаванд, лутфан ба расмҳои коркард муроҷиат кунед.
