Sodium Hydroxide Flakes, also known as lye and Caustic Soda Flakes, is an inorganic compound with the formula NaOH.
Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. Pvc Resin is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air.The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound.
Sodium hydroxide is used in many industries: in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents, and as a drain cleaner. Worldwide production in 2004 was approximately Boric Acid Flakes 60 million tons, while demand was 51 million tons.
Use Of Caustic Soda,Caustic Soda Pearls is also widely used in pulping of wood for making paper or regenerated fibers. Along with sodium sulfide, sodium hydroxide is a key component of the white liquor solution used to separate lignin from cellulose fibers in the kraft process. It also plays a key role in several later stages of the process of bleaching Water Treatment the brown pulp resulting from the pulping process.
With the improvement of our living standards, the use of soft furniture is becoming more and more widespread. For example, sofas, soft beds, soft chairs, and mattresses are products that are used in every home and office. Polyurethane foam is the main material of these furniture. Soft furniture has completely changed the traditional production process, and polyurethane foam is used in large quantities as an elastic material. The demand for polyurethane foam in the furniture industry is increasing year by year. As an important downstream industry of polyurethane soft foam, the furniture industry has continuously expanded the application range of polyurethane materials on furniture, improved the variety of furniture products, promoted a progress in furniture production, and then met the growing market demand. Many of the sofa cushions are made of polyurethane and are molded using foaming techniques using a mold. Water reacts with isocyanate to produce carbon dioxide and polyurea. Polyether reacts with isocyanate to produce polyurethane, and all these blends foam like noodles.
In the actual production, we use the mold to form the desired shape after the foam is initiated. This process is called reaction molding. After that, it is the post-processing process. This process is relatively simple. It is to put it in a free state to mature. Because foam is a viscoelastic material, its characteristics will change with time and speed, so it will generally be stationary for about 8 to 24 hours, and after its hardness is stabilized, it will be taken to the assembly plant. Wrapped, this is a cushion foam production process.
We need to make a cushion with beautiful appearance, comfortable body and reliable quality. We need to pay attention to many aspects in production. First, the fluidity is better, and the density distribution is "as far as possible". First consider the viscosity problem only the system viscosity is small, the initial fluidity will be good (main component of the average viscosity of 6000mPa.S or less, the combination of materials in 350mPa.S or less), followed by the system of potassium, sodium ions need to be controlled in a The lower limit (within 20 ppm) can be controlled to prevent the trimerization reaction from advancing, that is, the viscosity of the system will increase prematurely. If the fluidity is not good, the foaming material will go to the far end of the injection port and there will be drawing marks to make the cell structure football. This position must not resist low temperature shrinkage. At the same time is not conducive to complex mold casting. Therefore, viscosity measurement is performed at the beginning of the process, and the viscometer is generally used in the industry for monitoring.
Followed by fine cell, low thermal conductivity; resistance to low temperature anti-shrinkage performance is better; good adhesion; good security; to ensure the continuous stability of the foam production process and so on.
