  Basalt fiber   (Basalt Fiber, referred to as BF) is a new type of inorganic environmentally friendly high-performance material, the color is generally brown, some like gold. It is composed of oxides such as SiO2, Al2O3, CaO, FeO, and a small amount of impurities, and each component in the fiber has its specific properties. Basalt continuous fiber As a reinforcing material, basalt fiber not only has good stability, but also has excellent mechanical properties and corrosion resistance. In addition, it has the advantages of good insulation, excellent thermal insulation and sound insulation performance, and good wave transmission performance. Because basalt ore itself gives basalt fiber many excellent properties, basalt fiber itself has high durability and excellent mechanical properties, and these advantages are very practical in military and civilian fields. At present, the fireproof cloth woven from basalt fiber has been used in the production of flame retardant and heat insu...

  Velcorin , also known as dimethyl dicarbonate, is a preservative approved by the Ministry of Health and complies with the Food Sanitation Law of the People's Republic of China and the Food Additive Sanitation Management Measures. The molecular formula is C4H6O5, and the relative molecular mass is 134.09. The boiling point is 172 ° C, at room temperature, it is a slightly astringent colorless liquid, usually used in beverage cans. DMDC has a broad-spectrum antibacterial effect. Its main target microorganisms are yeasts (including Saccharomyces cerevisiae, Zygosaccharomyces ruckerii, Rhodotorula, Candida, Pichia, Toluobacillus, Torula, Endosporium, Klerkia, Hansenula, etc.). It also has a disinfecting effect on many other bacteria (such as Acetobacter pasteurianus, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, various lactobacilli, Pediococcus beer). DMDC has also been shown to kill E. coli 0157:H7. The antibacterial effect of DMDC is the result of inactivating e...

  Models of transdermal uptake of chemicals from clothing have been developed, but not compared with recent human subject experiments. In a well-characterized experiment, participants wore t-shirts pre-dosed with benzophenone-3 (BP-3) and BP-3 and a metabolite were monitored in urine voids.     Objective Compare a dynamic model of transdermal uptake from clothing to results of  the human subject experiment .   Methods The model simulating dynamic transdermal uptake from clothing was coupled with direct measurements of the gas phase concentration of  benzophenone -3 (BP-3) near the surface of clothing to simulate the conditions of the human subject experiment.   Results The base-case model results were consistent with the those reported for human subjects. The results were moderately sensitive to parameters such as the diffusivity in the stratum corneum (SC), the SC thickness, and SC-air partition coefficient. The model predictions were most sensitive t...

  The extent to which the flavor and texture of your food depends on how you break down and combine chains of protein, carbohydrate and fat molecules. This reaction is usually caused using heat, but you can also trigger or accelerate chemical reactions by introducing new enzymes into your food that can change the molecular composition. Cooking is one of the best examples of composites in our daily lives. A composite material is a combination of two or more constituent materials with different physicochemical properties; the resulting composite has properties that are different from those of the individual elements. Although composites are ubiquitous, we are often unfamiliar with the original elements used to make them and therefore cannot understand how the combination of materials changes the properties. But in cooking, you can experience the individual elements firsthand as you place them in a bowl and then create a new dish that tastes very different from each of the original in...

  Basalt is a hard, dense volcanic rock that can be found in most countries around the world. It is an igneous rock, which means it starts in a molten state. Basalt has been used in casting processes for many years to make tiles and slabs for architectural applications. In addition, cast basalt linings for steel pipes have shown very high wear resistance in industrial applications. Basalt is also used as an aggregate in concrete when crushed. Recently, continuous fibers extruded from natural refractory basalt have been investigated as an alternative to asbestos fibers in almost all of its applications. Over the past decade, basalt has emerged as a strong contender in the field of fiber reinforcement for composites. Proponents of this latecomer claim that their product offers similar properties to S-2 glass fibers at a price point between S-2 glass and E-glass, and may offer manufacturers a cheaper alternative to carbon fibers for producing the latter products representing over-desi...
