Two-component polysulfide sealant, as known as a two-component, non-sag, premium polysulfide sealant, which is also called polysulfide sealant for building made up of liquid polysulfide rubber, and add tackifying resin, vulcanizing agent, accelerant and fortifier into it. It contains two components and it can vulcanize and crosslink by itself at room temperature. The two components have clear color difference, which makes the mixing more convenient. It can keep good air tightness and water resistance in continuous vibration and temperature changes. In addition, it has a good bonding effect for metal, concrete and other materials. Application The polysulfide sealant is suitable for outdoor or indoor and can be used to seal both static and dynamic joints: Used to caulk at concrete, building, and bridge. Used in anti-leakage caulking of various types of expansion joints, such as waterworks, swimming pools, reservoirs, power plants, dams, sewage treatment works and water supply and drainage systems and other projects. Used as the joints of precast concrete, and the seams of the glass and construction. Used in the seaming of metal siding, and the bonding of aluminum window frame. Using method Add component B and pigment into component A; Stir quickly up and down until it is well mixed; Wipe the mixed sealant in the site where is waiting for construction with a small shovel; Don´t soak and contact with water within 48 hours after construction. Note Component B should be fully added into component A, which will affect the curing time and plasticity; The available time of mixed sealant is 2 hours. So the sealant should be used up as soon as possible after preparation to avoid the paste curing; The surfaces waiting for construction must be clean, dry and frost-free, and must be free of oils, grease, paints, coatings, sealers, curing compound residues, and any other foreign matter that might prevent adhesion; Notice to avoid water and rain within 48 hours after construction.

BOROSILICATE GLASS Clear borosilicate glass tube and rod Colored borosilicate glass tubes and rod Laboratory glassware Glass joint Other glass products made by boro 3.3 glass. - > RESISTANCE TO CHEMICAL Borosilicate glass is inert to almost all materials except hydroflouric acid (HF) phosphoric acid((H3Po4) and hot strong caustic solutions. Of these Hydroflouric acid has the most serious effect, even when it is present in PPM (parts per million) in solutions. Where as phosphoric acid and caustic solutions cause no problems when cold but at elevatrd temprature corrosion occurs. in case of caustic solutions upto 30% concentration can be handled safely at ambient temperature. Under actual operating conditions, the effect of turbulence, and traces of other chemicals in the solution may increase of decrease the rate of attack. So it is not possible to give exact figures for corrosion by caustic solutions. - > THERMAL PROPERTIES Linear coefficient of thermal expansion The coefficient of thermal expansion of borosilicate glass over the temperature 0 - 300�°C is 3.3 x 10-6/�°C. This is very low when compared with other glasses and metals. That is why, borosilicate glass is often called low expansion borosilicate glass. Specific heat Specific heat between 25C and 300C is average to be 0.233Kcal/Kg, C Thermal Conductivity Thermal conductivity is 1.0 Kcal/hr,mC. Over the permissible operating temperature range. - > RESHAPEING In the given below are shown characteristic temperature at a determined viscosity, essential for glass reshap. Lower cooling temperature 1024 poise 515C Upper cooling temperature 1013 poise 565C Softening point 107 poise 795C Reshapeing point 104 poise 120 C Specification of borosilicate glass 3.3
Cold Briquetted Iron (CBI) is defined as DRI which has been molded at a temperature less than 650 �°C or with a density of less than 5000 kg/m3. Due to the raw material sharp shortage for steelmaking in many countries worldwide, a need arises to find a substitute material to replace the rare pig iron and expensive steel scraps that were used by steelmaking plants. 1- More density and less porosity The apparent density of CBI is about 8.3 grams per cubic centimeter and the density of DRI is about 2.3 grams per cubic centimeter. On the other hand, the volumetric porosity of these two products is about 30 and 50%, respectively. These two factors reduce the environmental reactivity of CBIC and its lower transportation costs. 2- Less fine The wear resistance and higher mechanical strength of CBI compared to sponge iron causes less softening to occur during the handling of the product, and as a result, both the economic value of the product is prevented and the charge losses of the product in the steelmaking furnace are prevented. is significantly reduced. 3- Easier to store and carry Due to the lower reactivity of CBI compared to DRI, the loss of metal grade of the product during storage and transportation is significantly reduced, which will reduce the amount of economic value loss of the product from the time of production to the time of use in the steelmaking furnace. On the other hand, sea transportation of CBI leads to a reduction in transportation costs compared to DRI due to the absence of the need to apply neutral gas to prevent product activation. 4- More thermal and electrical conductivity The thermal and electrical conductivity of CBI is about 2 times that of DRI. This higher conductivity of CBI improves the distribution of heat created in the steelmaking furnace and, as a result, accelerates the melting process of iron materials. This will mean reducing the melting time of the steelmaking process and improving the production capacity of the steelmaking unit. 5- Carbon adjustment The presence of carbon in steelmaking furnaces is necessary in order to provide carbon for the final steel product, prevent excessive losses of iron, and also regulate the physical and chemical conditions of the slag. Usually, induction furnaces require low-carbon iron materials, but in electric arc furnaces, high-carbon iron materials are more attractive. The unique feature of CBI product is the ability to adjust its carbon content in the range of 0.5 to 4% by weight and based on the needs of customers.
