  Affected by public health incidents, NBR latex   is like a dark horse that has attracted the attention of the international market. Nitrile rubber and NBR latex are very different in use.   1. The difference in performance between nitrile rubber and NBR latex Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high abrasion resistance, good heat resistance, and strong adhesion. . Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used to make oil-resistant rubber products.   Carboxylic nitrile latex is obtained by introducing methacrylic acid or methacrylate ternary copolymer during polymerization. Since the carboxyl nitrile nitrile latex introduces a more polar carboxyl group into the molecular backbone, it furt...

  Sodium lauryl sulfate and sodium laureth sulfate The common denominator between sodium dodecyl sulfate (SLS) and sodium lauryl sulfate (SLES) is that both are surfactants. An aqueous solution of a surfactant dissolves oil or grease. So the oil on your skin can be washed with a surfactant. Surfactants work by reducing surface tension and thus produce more foam and are more flexible.   Why it is better not to use surfactants Surfactants can remove sebum and dirt, but their main drawback is that they easily dissolve skin natural oils. So too much use of surfactants can cause an uncomfortable barrier to your skin, and then your skin can get dry, flaking and dehydrated and may have spots and red patches.   Skin irritation due to Sodium Lauryl Sulphate laureth sulfate vs lauryl sulfate   is the most irritating to the skin. Despite all the negative reviews, there's no evidence shows that it's cancer or toxic. It is now used primarily to test the irritation of a small patc...

  If Potassium Iodide Becomes Potassium Iodate In Salt , Do You Dare To Eat Salt? What is the difference between potassium iodate salt   and potassium iodide, and what effect does it have on the human body?   Is potassium iodide a salt Iodine is an essential trace element in human body. It is an important raw material for the synthesis of thyroid hormone. Thyroid hormone affects the production, development and metabolism of the body. Iodine deficiency in infants and young children can lead to mental retardation. Adult iodine deficiency can easily lead to goiter. However, excessive iodine in the body can also lead to high iodine goiter, which can also affect health.   If Potassium Iodide Becomes Potassium Iodate In Salt, Do You Dare To Eat Salt?   Iodide vs iodate   are food nutrition enhancers added to the edible salt. At present, potassium iodate is mainly added to salt in China, while in the past it used potassium iodide. The advantage of potassium iodide...

  Is potassium iodide aqueous ? Potassium iodide is a white cubic crystal or powder. Potassium iodide is slightly hygroscopic in moist air. Potassium iodide precipitates free iodine for a long time and turns yellow, and can form a trace amount of iodate. Light and moisture can accelerate decomposition.   1 g of potassium iodide can be dissolved in 0.7 ml of water, 0.5 ml of boiling water, 22 ml of ethanol, 8 ml of boiling ethanol, 51 ml of absolute ethanol, 8 ml of methanol, 7.5 ml of acetone, 2 ml of glycerin, and about 2.5 ml of ethylene glycol. Its aqueous solution is neutral or slightly alkaline and can dissolve iodine. The aqueous solution will also oxidize and change to a yellow color, which can be prevented by adding a small amount of alkali. Its relative density is 3.12, the melting point is 680 ℃ , and the boiling point is 1330 ℃ . Its approximate lethal dose (rat, vein) is 285 mg/kg. It is widely used in the volumetric analysis of iodometric methods to prepare titran...
