Comparative analysis on the application of mica board and epoxy glass fiber board

Mica board and epoxy glass fiber board are often used in daily life. Today, we will make a comparative analysis of the application of mica board and epoxy glass fiber board. The first is the mica board:

Die glimmerbord het uitstekende buigsterkte en verwerkingsprestasie. Die glimmerbord het ‘n hoë buigsterkte en uitstekende taaiheid. Die glimmerbord kan sonder delaminasie in verskillende vorms verwerk word. Uitstekende omgewingsprestasie, die glimmerbord bevat geen asbes nie, het minder rook en reuk as dit verhit word, en is selfs rookloos en smaakloos.

Onder hulle is HP-5 harde mika-bord ‘n mica-plaatagtige materiaal met ‘n hoë sterkte. Die mika -bord kan steeds sy oorspronklike prestasie onder hoë temperatuurstoestande behou. Dit word wyd gebruik in die volgende velde:

Huishoudelike toestelle: elektriese strykysters, haardroërs, broodroosters, koffiemasjiene, mikrogolfoonde, elektriese verwarmers, ens.

Metallurgical and chemical industry: power frequency furnaces, induction heating furnaces, electric arc furnaces, injection molding machines, etc. in the metallurgical industry.

Epoxy glass fiber board: Glass fiber cloth is made by heating and pressing with epoxy resin. It has high mechanical performance at medium temperature and stable electrical performance at high temperature. 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. Heat resistance grade F (155 degrees). To

Die reaksie tussen die epoksiehars en die gebruikte geneesmiddel word uitgevoer deur ‘n direkte addisiereaksie of ‘n ringopenende polimerisasiereaksie van epoksiegroepe in die harsmolekule, en geen water of ander vlugtige byprodukte word vrygestel nie. In vergelyking met onversadigde polyesterharsen en fenolharsen toon hulle baie lae krimp tydens uitharding. Die geneesde epoksieharsstelsel het uitstekende meganiese eienskappe. Maar die algehele prestasie is nie so goed soos die glimmerbord nie.

Toepassingseienskappe

1. Verskeie vorme. Verskillende harse, verhardingsmiddels en modifikasiestelsels kan byna aanpas by die vereistes van verskillende toepassings op die vorm, en die reeks kan wees van baie lae viskositeit tot vaste smeltpunte.

2. Convenient curing. Choose a variety of different curing agents, the epoxy resin system can almost be cured in the temperature range of 0 ~ 180 ℃. 3. Strong adhesion. The inherent polar hydroxyl groups and ether bonds in the molecular chain of epoxy resins make it highly adhesive to various substances. The shrinkage of epoxy resin is low when curing, and the internal stress generated is small, which also helps to improve the adhesion strength.

Spesifikasie dikte: 0.5 ～ 100 mm

Konvensionele spesifikasies: 1000mm*2000mm

Kleur: geel, waterblou, swart

The hardness of epoxy glass fiber board is greater than that of mica board, but it is resistant to temperature difference.
