    摘要： Abstract: The present invention provides a method for producing high-activity lignin and by-product furfural and an application. The method comprises: using a dissolving pulp pre-hydrolysate and/or sulfite cooking liquor as the raw material, and catalyzing by employing an acid as a catalyst to obtain the lignin and furfural, wherein the acid is one or a combination of at least two of sulfuric acid, phosphoric acid, nitric acid, hydrochloric acid, and acetic acid. According to the method, the yield of the obtained lignin and furfural is further increased by catalyzing the dissolving pulp pre-hydrolysate and/or the sulfite cooking liquor with the acid. Lignin especially has higher reactivity and low molecular weight, and the ratio of 5-methyl furfural in furfural to furfural is in a proper range, so that the strength of furan resin prepared from furfural can be further improved.

    摘要： A curing agent for water glass molding comprises: ester; amorphous silica; and water. The amorphous silica is formed by means of a pyrolysis method and/or by means of a precipitation method. Also disclosed is a use of the curing agent for water glass molding in preparation of a casting mold and a mold core. Respective components of the curing agent comprising ester, amorphous silica and water are mixed at a high speed to form a suspension. Next, the suspension is applied to prepare a water glass self-hardening sand. The curing agent does not cause powder contamination, and can be measured and added conveniently. Also disclosed are a manufacturing method of the curing agent for water glass molding and a water glass self-hardening sand.

    摘要： Modified fiber and a preparation method therefor. By means of a physical method, uniform dispersion of graphite particles in a polyester base material and a polyamide base material is realized, the technology is simple, a dispersing agent is not needed, and industrial production is easy. By introducing graphene into hollow cotton or polyamide fiber, and particularly introducing biomass graphene into the hollow cotton or polyamide fiber, modified hollow cotton or polyamide fiber is enabled to have a low-temperature far infrared function, the far infrared normal emittance thereof being not less than 0.85; the antibacterial performance is greater than 90%; and the heat preservation performance and the air permeability are both remarkable, and when the content of the biomass graphene is 1.4%, the heat preservation rate is equal to that of white duck down and is about 90%, but the air permeability is about 240 mm/s and is far higher than that of the duck down.

    摘要： The present invention relates to a composite polyester material, a polyester fiber, processes for preparing the same and uses thereof. The polyester material and polyester fiber both comprise a composite having a carbon nanostructure, which comprises carbon element, from 0.5 to 4wt% of a first non-carbon non-oxygen element substance, and from 0 to 4wt%, of a second non-carbon non-oxygen element. The first non-carbon non-oxygen element is selected from the group consisting of P, Si, Ca, A1 and Na; the second non-carbon non-oxygen element is anyone selected from the group consisting of Fe, Ni, Mn, K, Mg, Cr, S or Co, or a combination of at least two selected therefrom. The G peak and D peak of the carbon element in the Raman spectrum has a peak height ratio of 1-20 in the composite having a carbon nanostructure. The present invention chooses a composite having a specific carbon nanostructure to compound polyester material and polyester fiber to obtain more excellent antibacterial effect and low-temperature far-infrared performance. The present invention further provides a simple process for preparing a polyester material compounded from a composite having a carbon nanostructure.

    摘要： A bonding agent for use in a 3D printing process comprises the following components: 15-60 parts by weight of a furan resin, 42-68 parts by weight of furfuryl alcohol, 1-12 parts by weight of an accelerator, and 0.1-5 parts by weight of an additive, wherein the said furan resin is prepared by the reaction of phenolic resin and furfuryl alcohol. Also disclosed are a preparation method and application of a bonding agent for use in a 3D printing process. The above bonding agent for use in a 3D printing process has an extremely low viscosity at room temperature, and its viscosity is lower than 10 mPa.s at 20 °C, thus meeting the resin requirements of the print head in 3D printing equipment, such that the print head is not easily blocked, thereby facilitating the maintenance of the machine. The bonding agent has good performance for wrapping sand particles in the process of sand applying, and the printed sand mold has higher mechanical strength and faster curing speed, thus facilitating sand dropping and cleaning and improving the operational performance.
