Caustic Soda (Sodium Hydroxide) – what is it used for ??
HD Chemicals Caustic Soda – what is its use at home, garden , DIY? The best known use is draining pipes. But caustic soda is also used in several other household situations, not only emergency ones. Caustic soda, is the popular name for sodium hydroxide. HD Chemicals Caustic Soda has a strong irritating effect on the skin, eyes and mucous membranes. Therefore, when using this chemical, you should take precautions – protect your hands with gloves, cover your eyes, mouth and nose. In the event of contact with the substance, rinse the area with plenty of cold water and consult a doctor (remember that caustic soda causes chemical burns and severe allergic reactions). It is also important to store the agent properly – in a tightly closed container (soda reacts strongly with... -
2022 Polypropylene Outer Disk Review.
Compared with 2021, the global trade flow in 2022 will not change much, and the trend will continue the characteristics of 2021. However, there are two points in 2022 that cannot be ignored. One is that the conflict between Russia and Ukraine in the first quarter has led to a surge in global energy prices and local turmoil in the geopolitical situation ; Second, US inflation continues to rise. The Federal Reserve raised interest rates several times during the year to ease inflation. In the fourth quarter, global inflation has not yet shown a significant cooling. Based on this background, the international trade flow of polypropylene has also changed to a certain extent. First, China’s export volume has increased compared to last year. One of the reasons is that China’s domes... -
Application of caustic soda in pesticide industry.
Pesticides Pesticides refer to chemical agents used in agriculture to prevent and control plant diseases and insect pests and regulate plant growth. Widely used in agricultural, forestry and animal husbandry production, environmental and household sanitation, pest control and epidemic prevention, industrial product mildew and moth prevention, etc. There are many varieties of pesticides, which can be divided into insecticides, acaricides, rodenticides, nematicides, molluscicides, fungicides, herbicides, plant growth regulators, etc. according to their uses; they can be divided into minerals according to the source of raw materials. Source pesticides (inorganic pesticides), biological source pesticides (natural organic matter, microorganisms, antibiotics, etc.) and chemically synthesized ... -
PVC Paste Resin Market.
Rise in Demand for Construction Products to Drive Global PVC Paste Resin Market Increasing demand for cost-effective construction materials in developing countries is estimated to boost the demand for PVC paste resin in these countries in the next few years. Construction materials based on PVC paste resin are replacing other conventional materials such as wood, concrete, clay, and metal. These products are easy to install, resistant to changes in climate, and less expensive and lighter in weight than the conventional materials. They also offer various advantages in terms of performance. Increase in the number of technological research and development programs related to low-cost construction materials, especially in developing countries, is anticipated to propel the consumption of PVC p... -
Analysis on the Changes in the downstream consumption of PE in the future.
At present, the main downstream uses of polyethylene in my country include film, injection molding, pipe, hollow, wire drawing, cable, metallocene, coating and other main varieties. The first to bear the brunt, the largest proportion of downstream consumption is film. For the film product industry, the mainstream is agricultural film, industrial film and product packaging film. However, in recent years, factors such as restrictions on plastic bags and the repeated weakening of demand due to the epidemic have repeatedly troubled them, and they are facing an embarrassing situation. The demand for traditional disposable plastic film products will be gradually replaced with the popularization of degradable plastics. Many film manufacturers are also facing industrial technological innovation... -
Production of Caustic Soda.
Caustic soda (NaOH) is one of the most important chemical feed stocks, with a total annual production of 106t. NaOH is used in organic chemistry, in the production of aluminium, in the paper industry, in the food processing industry, in the manufacture of detergents, etc. Caustic soda is a co-product in the production of chlorine, 97% of which takes place by the electrolysis of sodium chloride. Caustic soda has an aggressive impact on most metallic materials, especially at high temperatures and concentrations. It has been known for a long time, however, that nickel exhibits excellent corrosion resistance to caustic soda at all concentrations and temperatures, as Figure 1 shows. In addition, except at very high concentrations and temperatures, nickel is immune to caustic-induced stress-c... -
The main uses of paste pvc resin.
Polyvinyl chloride or PVC is a type of resin used in the production of rubber and plastic. PVC resin is available in white color and powder form. It is mixed with additives and plasticizers to manufacture PVC paste resin. Pvc paste resin is used for coating, dipping, foaming, spray coating, and rotational forming. PVC paste resin is useful in the manufacturing of various value-added products such as floor and wall coverings, artificial leather, surface layers, gloves, and slush-molding products. Major end-user industries of PVC paste resin include construction, automobile, printing, synthetic leather, and industrial gloves. PVC paste resin is increasingly used in these industries, due to its enhanced physical properties, uniformity, high gloss, and shine. PVC paste resin can be customiz... -

Methods to Enhance PVC Properties – Role of Additives.
PVC resin obtained from polymerization is extremely unstable due to its low thermal stability & high melt viscosity. It needs to be modified before processing into finished products. Its properties can be enhanced/modified by adding several additives, such as heat stabilizers, UV stabilizers, plasticizers, impact modifiers, fillers, flame retardants, pigments, etc. Selection of these additives to enhance polymer’s properties is dependent on end application requirement. For example: 1.Plasticizers (Phthalates, Adipates, Trimellitate, etc.) are used as softening agents to enhance rheological as well mechanical performance (toughness, strength) of vinyl products by raising the temperature. Factors that affect the selection of plasticizers for vinyl polymer are:Polymer compatibili... -
A polylactic acid 3D printed chair that subverts your imagination.
In recent years, 3D printing technology can be seen in various industrial fields, such as clothing, automobiles, construction, food, etc., can all use 3D printing technology. In fact, 3D printing technology was applied to incremental production in the early days, because its rapid prototyping method can reduce time, manpower and raw material consumption. However, as the technology matures, the function of 3D printing is not only incremental. The wide application of 3D printing technology extends to the furniture that is closest to your daily life. 3D printing technology has changed the manufacturing process of furniture. Traditionally, making furniture requires a lot of time, money and manpower. After the product prototype is produced, it needs to be continuously tested and improved. Ho...
