Abstract: A method of a polyurethane foam includes the following steps of: (1) simultaneously pumping a mixed solution prepared from hydrogen peroxide, an organic acid, a catalyst and a stabilizer and a vegetable oil into a first microstructured reactor of a micro-channel modular reaction device for reacting to obtain a reaction solution containing epoxidized vegetable oil; (2) simultaneously pumping the reaction solution containing the epoxidized vegetable oil obtained from the step (1) and a compound of formula III into a second microstructured reactor of the micro-channel modular reaction device for reaction to obtain a vegetable oil polyol; and (3) reacting the vegetable oil polyol prepared from the step (2) with a foam stabilizer, a cyclohexylamine, an isocyanate and a foaming agent cyclopentane for foaming so as to prepare a rigid polyurethane foam.

Abstract: The present disclosure discloses a sludge composite conditioner based on iron-containing sludge pyrolysis residue as well as a preparation method and use thereof. The sludge composite conditioner comprises iron-containing sludge pyrolysis residue and an oxidant used in combination with the iron-containing sludge pyrolysis residue, in which the iron-containing sludge pyrolysis residue is pyrolysis residue obtained by dewatering iron-containing sludge to obtain an iron-containing sludge cake and then pyrolyzing the iron-containing sludge cake, the iron-containing sludge being obtained from an advanced oxidation technology involving an iron-containing reagent.

Abstract: An additive manufacturing apparatus includes powder supplies, a preceramic binder supply, and a mixer device downstream from the powder supplies and the preceramic binder supply and configured to generate a powder-integrated preceramic mixture. The additive manufacturing apparatus also includes a nozzle device downstream from the mixer device and configured to output the powder-integrated preceramic mixture, and a heat source configured to heat the powder-integrated preceramic mixture to initiate a self-sustainable ceramization reaction to generate a ceramic matrix composite.
