An expansion joint or movement joint is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity
Dr. Wall Care Tile grouting is the process of filling the spaces in between tiles. It is high polymerized cementitious (in powder form) which requires addition of water to the powder to get a perfect product. A smooth surface gives a strong bonding with tiles. It is non porous, stain resistant, non shrink, water resistant, for interior & exterior use demonstrates an excellent water repellent property, suitable for joint width 1-4mm
Dr. Wall Care Stone Sealer is a siloxane penetrating sealer designed specifically for the treatment of Natural Stone surfaces. Sealer protects Natural Stone surfaces from exterior exposure and weathering. It is specially formulated sealer which penetrates deep into the surface pores, reacts chemically to provide a durable and long lasting barrier against water and salt intrusion. This level of protection can substantially reduce the damaging effects of freeze/thaw cycling, precipitation, acid rain, efflorescence and dust/dirt degradations.
Dr. Wall Care Weather Guard is a siloxane penetrating sealant designed specifically for the treatment of masonry materials and concrete surfaces. It protects concrete and masonry surfaces from the effects of exterior exposure and weathering. In all, it penetrates deep into the surface pores and reacts chemically to provide a durable, long lasting barrier against water and salt intrusion. This level of protection can substantially reduce the damaging effects of freeze/thaw cycling, precipitation, acid rain, efflorescence, and dust/dirt degradation. It preserves the natural appearance without membrane build-up

A calcium silicate insulation board is a non-asbestos insulation product that can withstand continuous working temperatures from 650 to 1100 . It is lightweight, has low thermal conductivity, high strength, is easy to install, reliable and durable. Available in 2 grades, 650 and 1000 and 1100, they are commonly used as a backup insulation for furnaces in the steel, petrochemical, ceramic, cement and glass industries or for fire protection in building construction. It not only saves energy but also increases productivity and provides protection for personnel in industrial safety. In housing construction, calcium silicate insulation board is also used as a fireproof insulation material for ceilings and walls and as a decorative sound-absorbing material.
Properties of calcium silicate insulation board
Thermal shock resistance and stability
Consistently low thermal conductivity
High structural strength at high temperatures
Non-combustible
Electrical insulation properties when dry
Easy to process
Insoluble in water, non-corrosive
Applications
The calcium silicate insulation board is easy to install and handle, and its low thermal conductivity makes it ideal for insulation. It is non-toxic and asbestos-free.
The calcium silicate insulation board is widely used in urban heat networks, metallurgy, electronics, machinery, steel, petrochemicals, ferrous and non-ferrous metal casting, aluminum, ceramics, glass and other industries.
Advantages of calcium silicate insulation board.
Asbestos-free
Product Description
Single Axis Foot Description
Constructed from strong, lightweight composite materials and an advanced design, it provides state-of-the-art single-axle feet. 10% to 20% lighter than traditional single-axle feet, this low-mobility model features neutral, realistic, waterproof makeup and interchangeable front and rear bumpers with three durometers. Supplied with moulded titanium pyramids.
The unique design feature of the single axis foot is a single articulating joint set at or slightly below ankle height.
The joint allows the toes to be raised (dorsiflexion) and lowered (plantarflexion) relative to the tibia. The amount of movement is determined by a rubber cushion within the ankle unit.
The cushion absorbs shock and cushions the user as he transfers weight from heel touch to toe off.

The casing cement-head with double plugs (called as cement-head ) is a common cementing tool used as wellhead unit in all kinds of cementing operation. Comparing to cement-head with single plug, it owns longer cement-head body , and upper rubber plug and lower rubber plug can be put in at same time.
The tool owns some advantages such as simple construction, easy operation, high pressure resistant, manifold in common use, flexible in connecting. Especially, the lever type indicator can shows whether rubber plug goes through double plugs cement-head to enter casing so that operator can determine easily.

PCE is a polycarboxylate based high range water-reducing admixture which enables concrete to be produced with very low water to cement ratios. Polycarboxylate superplasticizer is compatible with air-entraining agents, microsilica, accelerators and many other admixtures; however,each material should be added to the concrete separately.

Fiber cement boards are composite materials made of sand, cement and cellulose fibers. More specifically, they are composed of Portland cement with glass-fiber mesh on the surface. These boards can be used independently or along with plywood.
sodium lignosulfonate superplasticizer are surfactants. After they are added to concrete, the hydrophobic groups are directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. The cement particles with the same charge are mutually repulsed and dispersed under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculent condensate is released, so as to achieve the purpose of water reducing agent.
Therefore, adding wood calcium superplasticizer into concrete can reduce the water consumption of concrete mixture, reduce water cement ratio, improve workability, facilitate pumping and improve the strength, compactness and durability of concrete
In the rotary klin calcining petroleum coke, the petroleum coke is calcined in a natural way, and the temperature is at about 1350.The lining material hall be of good thermal shock resistance, small changes in the lining line and excellent abrasion excellence. The castable produced by our company adopts dense brown corudum and mullite as the aggregate and fine powder, mixed with 97 sillicon carbide to increase the thermal shock resistance and abrasion resistance, and ensure small changes in the lining line. In the process of use, each castable plate is tightly bonded, without seams and castable peeling. And the petroleum coke is not sticky to the klin wall in the calcining process.
