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. यसमा 1000V/MIL को डाइइलेक्ट्रिक शक्ति र 65 kV को ब्रेकडाउन भोल्टेजको साथ राम्रो विद्युतीय गुणहरू छन्, जसले उच्च भोल्टेज र वर्तमान वातावरणमा निरन्तर काम गर्न सक्छ।

3. यसमा बलियो मेसिनेबिलिटी, राम्रो मेकानिकल क्षमता, 303 MPa को कम्प्रेसिभ बल, 269 MPa को तन्य शक्ति, 455 MPa को झुकाउने बल, र 130 MPa को शियर बल छ। यसले बाहिरी संसारबाट कडा प्रभावहरू सामना गर्न सक्छ र राम्रो कठोरता छ।

4. रासायनिक गुणहरू पनि राम्रो छन्, जंग प्रतिरोध को एक निश्चित डिग्री संग।

5. यो गैर ज्वाला retardant, गैर-ब्रोमिन, EU मापदण्ड अनुरूप, वातावरण मैत्री, र वातावरण प्रदूषित छैन। विदेशमा यसको बढी प्रयोग हुन्छ ।

यो माथि देख्न सकिन्छ कि epoxy ग्लास फाइबर बोर्ड को प्रदर्शन धेरै राम्रो छ। यो गिलास फाइबर पानाबाट बनेको छ जसलाई इपोक्सी रालसँग बाँधिएको निरन्तर फिलामेन्टले बुनेको छ। यो सीधा ग्राहक आवश्यकताहरु अनुसार अनुकूलित गर्न सकिन्छ। यदि प्रशोधित भागहरू प्रशोधन गरिन्छ भने, कृपया रेखाचित्र प्रशोधनलाई सन्दर्भ गर्नुहोस्।
