In the sealing material, much industrial waste gypsum is used as gelatinization materials, so that performance of sealing mortar can be improved, material cost is reduced, pollution control and emission reduction are facilitated, and a new way for resource utilization of the industrial waste gypsum is provided.

The invention discloses a sealing and anti-corrosion protection method of a suspension bridge cable system, and belongs to an anti-corrosion protection method of a bridge cable. The method helps divide the whole cable system into 7 types of surfaces: an outer surface of a main cable of a wire wrapping section; the outer surface of the main cable of a non-wire wrapping section; the outer surface of a main cable saddle exposing a strand; the outer surfaces of a cable strand inside an anchor chamber, a sling wire rope, as well as a railing rope and a side rope of a maintaining roadway; the outer surfaces of a cable clamp, a cable saddle (sleeve) and a saddle, and exposed surfaces of bolts and nuts; the outer surfaces of an anchor cup, a sling clamp, a sling shock mount, and columns and brackets of the maintaining roadway; and gap sealing surfaces of the cable clamp, a cable jacket girth seam, an abutted seam and a top saddle opening. The 7 types of the surfaces are treated by different methods, and the sealing and anti-corrosion method is complete. In the method, novel sealing materials and anti-corrosion paints are used, which has good sealing performance, long anti-corrosion service life and high strength, and ensures the durability of the suspension bridge cable system.

There is provided a process for disposal of waste diatomaceous earth discharged from a filtration operation, etc. of various production plants, which process excels in handling easiness and in fuel cost for drying and realizes obtaining of high functional capability at low cost through, for example, holding and controlling of organic components, such as enzymes and yeasts, contained in waste diatomaceous earth and utilization of the functional capability thereof. Further, there is provided a diatomaceous earth composition for building containing a porous inorganic material such as fired diatomaceous earth and a cement for use as a coating material applied to panels, walls, etc. The composition is capable of preventing dew condensation, and is applicable without compulsory pressurization on a wood sheathing by means of coating roller, brush, spray coating, etc. Furthermore, the composition for building without exception is substantially from any color fade-out phenomenon due to coloring by natural soil grains. Still further, a certain effect of powerful photocatalyst redox reaction impact by titanium dioxide exposed to air on the decomposition of harmful pollutants of the atmospheric air is promising by causing the composition to contain a powdery porous inorganic mineral as a main component and titanium oxide as a pigment.

The invention relates to a preparation method of a scratch resistant double-component polyurethane woodenware glossy vanish. The vanish is composed of a resin paint component A and a curing agent component B, wherein the weight ratio of the component A to the component B is 1:0.5; the resin paint component A is composed of alkyd resin, acrylic acid resin, aldehyde-ketone resin, a chelating leveling agent, an antifoaming agent, and a solvent; and the curing agent component B is composed of a TDI-HDI mixed trimer or a TDI / TMP adduct, a HDI trimer, and a solvent. The prepared vanish has the advantages of high hardness, low viscosity, and good leveling property. The paint membrane has high gloss and an appearance like a crystal or a jade, is transparent, thick, and smooth, can give people a high class feeling, can create a mirror-liked decoration effect, is capable of forming a refreshing, grace, concise and tranquil space, brings a relaxed and happy sense to people, is accord with the modern aesthetics, is welcomed by the market and customers, and is widely used to protect and decorate surfaces of woodenware, metal products, and plastic products.

The invention discloses a net rack production line for producing a heat insulation board wall. The net rack production line comprises a flat net welding machine for welding already straightened longitudinal bars and transverse bars into flat net layers, a heat insulation board cutting machine for carrying out heat insulation board cutting in the thickness, length and width directions of an heat insulation board and forming the heat insulation boards meeting the specification requirements by cutting, an oblique inserting rib welding machine for inserting oblique inserting ribs into the heat insulation board and welding the oblique inserting ribs to the two flat net layers up and down, and a net rack heat insulation board conveyer for conveying an already produced net rack heat insulation board; the feed end of the oblique inserting rib welding machine corresponds to the discharge end of the flat net welding machine and the discharge end of the heat insulation board cutting machine; thedischarge end of the oblique inserting rib welding machine corresponds to the feed end of the net rack heat insulation board conveyer; and the flat net welding machine, the heat insulation board cutting machine, the oblique inserting rib welding machine and the net rack heat insulation board conveyer are each provided with control equipment for controlling various mechanisms in the flat net welding machine, the heat insulation board cutting machine, the oblique inserting rib welding machine and the net rack heat insulation board conveyer to carry out coordinative operation. Welding productionof the flat nets, efficient cutting of the heat insulation board, accurate insertion and welding of the oblique inserting ribs, conveying and transportation of the net rack heat insulation board are integrated in the net rack production line, so that the effect of efficiently producing the net rack heat insulation board throughout is realized.

This invention is about fridge double drawers. It includes the main drawer, which preserves food; the assistant drawer, which can house the main drawer. It has pullout rail that can make the main drawer slide forwards and backwards at the inner side; and the guiding rail setting at both sides of assistant drawer. It guides the assistant drawer to slide forwards and backwards; and the separator, which divides the inner space of assistant drawer into front and backsides. This invention can increase the space utilization of the inner space of fridge.

The invention relates to a preparation method of a benzene-free odor-free scratch-resistant polyurethane matt gloss white topcoat for woodware. The benzene-free odor-free scratch-resistant polyurethane matt gloss white topcoat is composed of a component A and a component B which are in the weight ratio of 1:0.5, wherein the component A is composed of odor-free alkyd resin, titanium dioxide, matting powder, calcium carbonate powder, a dispersing agent, an anti-yellowing agent, a flatting agent, a hand feeling agent, a defoaming agent, an anti-settling agent and a solvent; and the component B is a benzene-free curing agent with TDI, an HDI tripolymer or an addition product as a main component. The matt gloss white topcoat prepared by using the preparation method does not contain arene, aldehyde ketone or heavy metals, and no residual odor is left on a paint film after 48 hours; the matt gloss white topcoat can not be settled when being stored, is good in flatting performance, capable of forming a thick film at one step without sagging, soft in hand feeling, full and exquisite, slippery, good in scratch resistance and capable of generating a mirror-surface-like full decorative effect and bringing elegance and comfort for people, and conforms to the modern aesthetic view so as to be popular to the market and consumers; and the matt gloss white topcoat is widely applied to the surfaces of woodware, metals, plastics and other products to take protective and decorative effects.
