Polyurethane phenolic insulation board equipment is a new type of building materials equipment, the main production process is feeding, mixing, injection molding, foam foam, the following look at the specific introduction.
①, feeding, mixing: through the feeding system will be quantitative cement, foam agent, foam stabilizer added to the mixer, dry mix for 30 seconds.
②, stir: the amount of warm water into the mixer, wet stirring for 2 minutes; the amount of the blowing agent into the mixer for 8-15 seconds.
③, injection molding, foaming: Immediately into the mold into the mold foam, foaming process about 3-5 minutes.
④, stripping: foam insulation board to be completed to complete the initial coagulation, with the initial strength can be stripped.
⑤, cutting: with a certain strength of the foam insulation board blanks after stripping can be cut, cutting specifications according to the need to adjust the cutting blade.
⑥, the initial maintenance: After the completion of injection molding for several hours after the initial maintenance.
⑦, finished product conservation: foam cement insulation board maintenance age should not be less than 7 days.
