The invention discloses a flexible prediction method for an industrial enterprise micro-grid energy load model, and particularly relates to the technical field of micro-grid energy load model flexible prediction. Different physical stages of load climbing, inertia release and stable operation are effectively distinguished, the situation that the inertia slow change process is misjudged as prediction model mismatch is avoided, meanwhile, the time decoupling degree between production plan triggering and actual load response is quantified through a load inertia dominant factor, and the prediction model mismatch accuracy is improved. The flexible prediction model does not blindly follow short-term fluctuation in the weight adjustment process, and continuous collaborative updating of load inertia characteristics and prediction model parameters is achieved through an online correction mechanism based on prediction residual errors.

The present application relates to the technical field of waterborne polyurethane materials, and particularly relates to a low VOC waterborne PU foam pad and a preparation method thereof. The foam pad is formed by foaming and curing of a waterborne polyurethane dispersion, and two types of aldehyde-trapping sites are simultaneously introduced into the same porous framework, i.e. an amidoxime group formed by post-conversion of a nitrile group precursor by hydroxylamine, and an aminooxy group obtained by coupling and deprotection of T-BOC-aminooxy-diglycol-amino through a carboxyl anchoring site under an EDC and NHS activation system; and a water-dispersible blocked polyisocyanate crosslinking agent is used to form a crosslinking network by pyrolytic deblocking, so as to achieve rapid capture and durable retention of aldehydes such as formaldehyde and acetaldehyde under water washing and humid heat conditions, and simultaneously help to reduce VOC emission of the material.
