Background technology
In photovoltaic module produces, installing rosette operation is one critical process, in rosette operation is installed, need to be
In rosette, as insulating radiation filler, double-component silica gel is made up of injection embedding double-component silica gel two kinds of glue of a, b, a class
Glue is referred to as base rubber, and b class glue is referred to as firming agent, can use, casting glue after a, b class glue mixes according to a certain percentage
Hardening time can be adjusted according to mixed proportion.Current a, b mixing machine in use, is static mixing tube,
Two component in static mixing tube, in 4 hours must in every 8 minutes injecting glue once, after otherwise solidifying, static mixing tube
Must change.After static pipe uses 4 hours, even if not stopping dumping, static mixing tube also can be because of glue to mixed glue core body
Attachment, becomes blocking it is necessary to change, the surcharge of production is very high.Change static mixing tube and have an effect on production efficiency, make production
Line production capacity declines.
