Mineral wool interted preferably undertaken by different azimuth when grabbing reason, the ratio that pushes linear velocity and shaping mould linear velocity first approximates the unit weight of profiled sheeting and the ratio of charging mineral wool unit weight, can repeatedly slow down between the first-elected and moulding.
Be heating and curing and can use electric energy, conventional electrical heating, hardening time is longer, and the most handy microwave is forced heat supply, and also available hot blast forms pressure reduction and forces heat supply with mould, and its magnitude of pressure differential determines that according to the compactedness of mineral wool board compactedness is big, pressure reduction is also big.Then determine hot blast temperature and hardening time according to the kind of used binding agent.
Former of the present invention provides a kind of embodiment of above-mentioned forming method.
This equipment mainly comprises cotton circulation road, first-elected roll, push away again roll, chain mould and hot blast with holes spray suction pipe.
The raw material cotton is from feeder connection, successively through first-elected bar, push rod interts and grabs reason again, its machine direction is changed and is disordered state, in moderating process, compress and enter the chain mould gradually along plate face direction, chain mould hot blast spray suction pipe with holes up and down forms pressure reduction, in type mineral wool board is forced heat supply, make its solidifying and setting.
Further explain and explanation below in conjunction with drawings and Examples:
