The invention provides a structural mechanics experiment platform and belongs to the field of structural mechanics experiment teaching of the major of civil engineering. An upper cross beam, a lower cross beam, upright columns and tie beams form a space reflexive force loading frame through an assembling mode; an H-shaped steel beam in the upper cross beam, the lower cross beam and the web plates of the upright columns are each provided with a linear guide rail; the linear guide rails are provided with sliding dolly platforms, the sliding dolly platforms can be fixed at any positions of the linear guide rails; and an experiment model and a loading device are installed on the sliding dolly platforms. According to the invention, auxiliary devices such as a mobile short upright column, a constraint cross beam, an intermediate cross beam providing a horizontal counterforce and the like are configured, multiple constraints and multi-point multi-directional tensile compression loading on the experiment model are realized, and the quantity, the positions and the directions of constraint points and loading points and the dimensions of the experiment model are not restricted in an effective experiment space. The platform is of a space structure, the experiment space is open, the loading means are abundant, multiple groups of contrast experiments and autonomous design comprehensive experiments are carried out at the same time, and open experiment teaching is facilitated.

The invention discloses a coproduction technology of titanium white, iron oxide red and polymerized chlorinated ferrous sulfate. The coproduction technology comprises the following steps: crushing andgrinding ilmenite and conveying to be subjected to sulfuric acid process titanium white production and ilmenite pre-reduction treatment respectively; obtaining titanium white powder, FeSO4.7H2O and waste acid in the sulfuric acid process titanium white production; adding the ilmenite subjected to the pre-reduction treatment into waste acid and reacting to obtain synthetic rutile and a saturated FeSO4 solution; adding an NaOH solution into the saturated FeSO4 solution and introducing air under a stirring condition to obtain iron oxide black; calcining iron oxide black in a rotary kiln to obtain iron oxide red; carrying out chlorination process titanium white production on the synthetic rutile to obtain the titanium white powder, hydrochloric acid and CaCl2; putting the saturated FeSO4 solution into a sealed container and introducing chlorine gas and reacting to obtain polymerized chlorinated ferrous sulfate; carrying out mixed firing on the FeSO4.7H2O and coal to prepare sulfuric acidand iron oxide. According to the coproduction technology disclosed by the invention, byproducts produced in each section of the technology are effectively utilized, the production cost is greatly reduced and green circulation economy advocated in China is met.

An ethyl cellulose-based self-healing polymer and a preparation method thereof, which utilizes modified ethyl cellulose containing furan groups and 4,4'-methylenebis(N-phenylmaleyl imine) prepared by the Diels-Alder reaction. Thermoreversible Diels-Alder (DA) bonds can be introduced into self-healing polymers by adjusting the content of 4,4'-bismaleimidodiphenylmethane to obtain polymers with different mechanical properties and self-healing properties Material. Surface cracks in the polymer material can be repaired by heating, and the damaged material can be recycled through a thermoplastic process.

The invention discloses a marine fish peptide containing galangal and a preparation method thereof. The method comprises: mincing marine fish meat into mince, adding water and mixing, enzymolyzing protease to obtain an intermediate product, then adding galangal dry powder and fully mixing, performing enzymatic starch removal and alkali extraction treatment, centrifuging, washing the filter residue with water, and combining The supernatant is concentrated under reduced pressure and spray-dried to obtain marine fish peptides. The total protein content of the marine fish peptide is more than 55%, the proportion of soluble peptides to the total protein is more than 96%, the total sugar content is more than 30%, the proportion of polysaccharides to the total sugar is more than 40%, and the content of galangal flavonoids is more than 0.16‰. It has good water solubility and has Galangal has a special flavor, no fishy smell, low hygroscopicity, and can effectively inhibit the activity of xanthine oxidase. The invention can improve the anti-hygroscopicity and flavor characteristics of the marine fish peptide, and enhance its xanthine oxidase inhibitory activity. The whole technological process can meet the requirements of food grade, and can be applied to the fields of common food and health food.
