There are many types of photovoltaic junction boxes, but the basic structure is the same, solar junction box including box body, box cover, connector, terminal block, diode, solar junction box etc. Some junction box manufacturers have designed heat sinks to enhance the temperature distribution in the box, solar junction box and some The junction box manufacturer has made other detailed designs, but the overall structure has not changed.
Photovoltaic junction box potting glue requirements: curing at room temperature, fast curing, solar junction box no shrinkage during curing, high production efficiency, easy to use; low viscosity, good fluidity, good self-draining foam, solar junction box can be poured to subtle places, and can be more efficient Convenient potting and sealing of complex electronic components;solar junction box maintain rubber elasticity in a wide temperature range (-600C-2500C), excellent electrical properties, solar junction box and good thermal conductivity; waterproof and moisture-proof, flame retardant, chemical resistance, and yellowing resistance , solar junction box Weather-resistant aging for more than 25 years; good adhesion with most plastics, rubber, solar junction box reinforced nylon PA and polyphenylene ether PPO; fully meets the requirements of relevant standards;
The photovoltaic module sealant itself is non-toxic, solar junction box but its additives may contain certain toxicity or irritation. Different manufacturers have different formulas. For detailed hazard data, solar junction box please refer to the hazard overview and toxicology data in the product introduction provided by the manufacturer. The quality report of photovoltaic sealants produced by regular manufacturers can be obtained from them.
