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:

Ny tabilao mika dia manana tanjaka miondrika tena tsara sy fahombiazan’ny fanodinana. Ny tabilao mika dia manana tanjaka miondrika avo sy henjana tsara. Ny tabilao mika dia azo zahana amin’ny endrika maro tsy misy fanamorana. Fampisehoana tontolo iainana tena tsara, ny tabilaon’ny mika dia tsy misy asbestos, kely kokoa ny setroka sy ny fofona rehefa mafana, ary tsy misy setroka sy tsy misy tsirony.

Anisan’izany, ny tabilaon’ny mika mafy HP-5 dia fitaovana toy ny takelaka mika avo lenta. Ny tabilaon’ny mika dia mbola afaka mitazona ny fahombiazany tany am-boalohany eo ambanin’ny toetr’andro avo. Ampiasaina amin’ireto sehatra manaraka ireto izy io:

Fitaovana ao an-trano: vy misy vy, fanamainana volo, toasters, mpanamboatra kafe, lafaoro mikraoba, heater elektrika, sns.

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

Ny fanehoan-kevitra eo amin’ny resin epoxy sy ny mpitsabo dia ampiasaina amin’ny alàlan’ny valim-panampiana mivantana na ny valin’ny polymerization an’ny vondrona epoxy ao amin’ny molekiola resin, ary tsy misy rano na vokatra hafa miovaova navoaka. Raha ampitahaina amin’ny resins polyester tsy miangona sy resins phenolic dia mampiseho fihenam-bidy ambany be izy ireo mandritra ny fanasitranana. Ny rafitra resin epoxy resahina dia manana toetra mekanika tena tsara. Fa ny fahombiazana ankapobeny dia tsy tsara toa ny board mica.

Toetra mampiavaka ny fampiharana

1. Fomba isan-karazany. Ny resins isan-karazany, ny mpitsabo, ary ny rafitra mpanova dia saika afaka mifanaraka amin’ny takian’ny fampiharana isan-karazany amin’ny endrika, ary ny elanelam-potoana dia azo avy amin’ny viscosity ambany dia ambany ka hatramin’ny solids point de poissant avo.

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.

Famaritana matevina: 0.5 ～ 100mm

Famaritana mahazatra: 1000mm * 2000mm

Loko: mavo, manga rano, mainty

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