Although fat annulus a group of things with common features the recipe of epoxy resin is very much, the breed of porcelain is very much also, avery kind of has his specific quality and parameter, but have a few general comparison. Above all, in physical domain, the following relation is typical: •Fat annulus a group of things with common features 70% what the weight of epoxy resin is less than china weight, that is to say, epoxy resin insulator is a lot of lighter than porcelain insulator weight. •The hot coefficient of expansion of epoxy resin is the 1/20 of porcelain. •The tensile strength of epoxy resin is glaze porcelain 11 times the left and right sides. •The 4-6 that the compressive strength of epoxy resin is glaze porcelain times. •The bending strength of epoxy resin is glaze porcelain 16 to 18 times. •Epoxy resin impact strength, without breach, roughly as identical as glaze porcelain. •Epoxy resin controls dimension and appearance more easily than china. •Although the reparability of epoxy resin is finite, but china cannot repair. In electric field, you can discover: •The dielectric constant of epoxy resin is porcelain only 2/3 the left and right sides. •The temperature grade outclass of china of annulus, but temperature grade is 105 C or the annulus mixture of 130 C is obtained very easily. •Of epoxy resin be able to bear or endure ability compares electric mark porcelain slightly small. •The bibulous rate of epoxy resin is more than china slightly, but still be inside the limits of the 2/10 of 1% . Finally, epoxy resin is shown to common industrial chemical be able to bear or endure exceedingly goodly suffer a gender, clean easily, have fight exceedingly goodly aggressivity and be able to bear or endure await a gender. Anyhow, we believe the function of exceedingly good physics of epoxy resin makes its make the insulating material of first selection, although be in,electric performance side has a few small sacrifice. The application that high strength needs below this acuteness to be in dynamic load especially such, for example the insulator propping up in breaker and switchgear. Epoxy resin has exceedingly good insulation property, technology of APG pressure gel improved product quality and performance greatly, the question of epoxy resin insulating part is more obvious also.
The operation safeguard of epoxy resin needs a lot of, need protection dress, glove, goggles / safe glasses, recommend guaze mask / dustproof mask. The processing of slop content, suck with sawdust or cotton waste silk, and park is plastic braid basket inside.

Emergency treatment
Get when the eye agent of colophony, solidify or pouring when the flyblow of makings, should be used clean instantly, going from place to place water is rinsed 10 to 15 minutes. Want to see a doctor. Touch or splash the material on the skin to want erase, scour contaminative place with running water next. If serious ache or burn, want to see a doctor. Dirty clothes should change instantly. Bring about because of inspiratory steam unwell, should move instantly piece outdoors. If have doubt, hang down namely please help of ask medical treatment.
Specific power consumption of epoxy resin production process is tall, manufacturing process heats tall, time grows temperature.
Manufacturing process, craft of mould temperature APG: 130 - 160°C, traditional vacuum is pouring 70 - 100°C
Time of drawing of patterns (depend on mould temperature and pouring bulk) , APG craft: 10 - 40 Min, traditional vacuum is pouring 5 - 8h
Solidify condition, APG craft (least solidify time) 4h 130°C or 3h 140°C, traditional vacuum is pouring: 12h 130°C or 8h 140°C.
Litter is torn open hard solution, unmanageable
Sex of solidify hot solid is plastic do not belong to dangerous trash, can adopt fill bury pattern processing. In fact, this kind of trash of 90% above uses processing of this kind of pattern. But increase in great quantities as deserted material, the space that together with handles these waste material is limited, because this need uses the more advanced, technology recycle that can last these material.
Recycle of hot solid sex these flotsam come up from economic benefits as housing materials say attraction is not big, epoxy resin material applies extensively at electric equipment insulation, this means what must want cleared interior before repeated usage all sorts of metal component (core, winding) . Some companies use microtherm to handle the annulus oxygen part that contains metallic insert, but be reclaimed gotten material quality is inferior.
Use project is plastic thermoplastic material, manufacturing efficiency is tall, specific power consumption is low, function and epoxy resin are identical.
