2023-06-02
Main classification
There are many makes and models of foaming machines, but from the foaming principle, the only three types that are widely used are the high-speed impeller type, the high-pressure air type and the low-pressure blower type. The differences in the same type are only in the ancillary equipment and automation control, the structure of the foaming part is largely the same.
Production process
1、Feeding and mixing: add the quantitative cement, foaming agent and foam stabilizer to the mixer through the feeding system and dry mix for 30 seconds;
2、Mixing: add quantitative warm water into the mixer, wet mixing for 2 minutes; add quantitative foaming agent into the mixer and mix for 8-15 seconds;
3, injection, foaming: then inject the slurry into the mould foaming, foaming process of about 3-5 minutes;
4、Initial maintenance: after the completion of mould injection, leave it for some hours for initial maintenance;
5、Demoulding: when the initial set of foamed cement insulation board is completed, with the initial strength can be demoulded;
6, cutting: with a certain strength of foam cement insulation board blanks can be cut after demoulding, cutting specifications according to the need to adjust the cutting blade for;;
7, finished product maintenance: foam cement insulation board maintenance age should not be less than 7 days.
