The invention provides a foaming-ceramic heat insulating board. The foaming-ceramic heat insulating board is characterized by being prepared from, by weight, 25-30 parts of fusible clay, 6-12 parts of diatomaceous earth, 6-12 parts of alkalifeldspar, 5-10 parts of dolomite, 2-5 parts of starch, 6-12 parts of nano-scale silica fume, 6-12 parts of cement, 6-12 parts of lime, 1-2 parts of anionic surfactant, 0.5-3 parts of foaming agent, 1-4 parts of reinforcing elements, 0.1-0.5 part of triton X-100 and 100-190 parts of water; the reinforcing elements are titanium-system reinforcements or aluminum-system reinforcements or boron-system reinforcements or silicon-system reinforcements. The foaming-ceramic heat insulating board is low in heat conductivity coefficient, high in breaking strength, low in density and not prone to water permeation, and can be widely used for wall materials, heat insulating materials and underground engineering materials. As the triton X-100, the anionic surfactant and the starch are combined to be used, the porosity rate of the board is increased, and bubbles can be more evenly distributed.

The invention discloses a making process of a gold silk skin-nourishing quilt, and particularly relates to the field of processing articles for daily use. The making process includes steps: selecting cocoons, dipping, permeating, steaming, adjusting, degreasing, poking the cocoons, opening, rinsing, drawing, and detecting a quilt core. Gold cocoons are boiled through process of dipping, permeating, steaming and adjusting, so that length and toughness of subsequent silk can be ensured, and sufficient permeation of silkworm cocoons can be ensured,]; degreasing duration is shortened, so that impact on glossiness and smoothness when gold silk is corroded by degreasing powder for a long time can be avoided; a mode of drawing by four persons is adopted in the drawing process, a 'full-width plane net overlapping process is adopted, and the quilt core is fixed layer by layer in a crisscrossed manner, so that process effect of being free of renovation within 20 years is realized. Uniformity and service life of silk in all aspects of the whole quilt are ensured, displacement of a quilt batt is avoided effectively, and service life of the silk quilt is ensured.

The invention provides high-efficiency low-cost textile size and a sizing technology. The high-efficiency low-cost textile size and the sizing technology solve the problems that the opening in the spinning process is unclear, the fragment of the textile generates cotton balls, the permeation effect is poor, the coating capability to yarns is improved, the flexibility of sizing membranes is improved, the abrasive resistance of the sizing membrane and the strength of the yarns are improved, the weavability of the product is greatly improved, the cost is lower. and the popularization is facilitated.

The invention discloses a method for extracting vavasu (one kind of isoflavone compounds) from Ceiba pentandra (L.) Gaertner. The method comprises the steps of taking tree barks of the Ceiba pentandra (L.) Gaertner as a raw material, crushing and then extracting the raw material in a fluid dynamic continuous countercurrent extraction device, putting the extraction solutions together to recycle ethanol, conducting purification by means of membrane separation, adsorbing by polyamide resin column on a permeation solution, eluting water and alcoholic solution, collection target components, concentrating the solution, extracting the concentrated solution by ethyl acetate, concentrating the extraction solution to a small size, standing by to crystalize the solution, recrystallizing crystals by using acetonitrile-dichloromethane, and then freezing and drying the crystals to obtain the vavasu. The process is simple in process, high in extraction efficiency and low in cost, thereby being quite beneficial to industrialized production.

The invention discloses a stainless steel pipe with a deviation preventing function. The stainless steel pipe comprises a pipe base layer, a permeation preventing layer, a reinforcing layer, a clamperand an indicating arrow; the permeation preventing layer is arranged on the outer side wall of the pipe base layer; the reinforcing layer is arranged on the surface of the side, far from the pipe base layer, of the permeation preventing layer; an outer layer is arranged on the surface of the reinforcing layer; lifting sunk cavities are formed in the outer side walls of the two ends of the outer layer; a treatment panel is fixed in the center position of the surface of the outer layer; a single-chip microcomputer is mounted on one side in the treatment panel; a Bluetooth transmission module isfixed at the end, far from the single-chip microcomputer, of the treatment panel; the clamper is fixed at the end, far from a connecting cavity, of the pipe base layer; an arc anti-falling strip is arranged on the outer side wall of the clamper; and an infrared light receiver is arranged in the pipe base layer on the outer side of the clamper. The stainless steel pipe achieves the deviation warning function in use to improve the connecting firmness, and improves the paving convenience degree.
