FRP pultruded profiles mold fiberglass pultruded profiles key factor in pultrusion die in a portfolio of diversified market, the main small products. And most of the FRP profiles FRP pultruded profiles are all made of die purposes. Meanwhile FRP pultruded profiles produced by mold in the implementation process, the factors that affect the pultrusion process are the following: (1) row yarn systems: the fiberglass roving fabric or pre-distribution systems. When the fiber-reinforced material transport platoon yarn, flat yarn row for ordinary rotary spindle fibers drawn from the bobbin wall, so to avoid reverse phenomenon. http://www.hbsqlbs.com/news/gs/278.html (2) Natural resin impregnation: the process is to have a good natural resin glue arranged on formulated neat and smart glass fiber mat and the average impregnation. Natural resin impregnated fibers and ordinary at the time felt through the plastic tank is equipped with the implementation of natural resin, commonly used long trough dipping. In wholeness impregnation process, be sure to protect the fiber and felt very tidy arrangement. (3) preforming: preforming device consists of a manifold, shunt bracket and guide bracket components. Good prepreg material over the preformed fiber supplement means to operate won form, in order to ensure their relative positions; means the impregnated preform by good fiber supplement material gradually transition to approximate pattern profile, while the extrusion superfluous natural resin; then entered the mold, molding curing purposes. General guide bracket at the entrance in the mold, preforming device and fiber-reinforced material should contact the outer trim Guangliu avoid shaving the fiber. (4) molding and curing: already have profiles approximate plot style dipping into the mold of a fiber-reinforced material, in the mold curing purposes. Temperature of the mold on the basis of natural resin system design purposes, mainly based on natural resin exotherm and friction properties of materials and mold. Common mold into a preheating zone, a gel zone and curing zone two different heating zones, in order to curb the curing speed. Die pultrusion process is the most critical part, the length of the die typically ranges between 0.6 ~ 1.5m. (5) Drag cutting: FRP pultruded profiles in the mold, towing device may be a type of caterpillar tractor, it has solidified profiles pull out from the mold. Normal tension should have more than 98kN.
