What are the environmental benefits of using beeswax and cornhusk to create waterproof paper bags?5 answersThe environmental benefits of using beeswax and cornhusk to create waterproof paper bags are significant. Beeswax, when modified and applied to paper, provides excellent waterproof and oil-proof properties, allowing for the production of environmentally friendly food packaging that can replace non-biodegradable materials like PE paper. On the other hand, cornhusk fiber, when subjected to graft copolymerization with certain compounds, can enhance the strength of the paper and improve its resistance to corrosion and moisture absorption deformation. This results in the creation of degradable waterproof paper that is not only eco-friendly but also enhances the overall properties of the paper, making it suitable for various packaging applications, including in water environments.
Can beeswax use for waterproofing fruit leather?5 answersBeeswax can indeed be used for waterproofing fruit leather. Research suggests that a composition containing beeswax, paraffin wax, and a fatty acid dispersed in an aqueous alkaline solution can create a waterproof coating for cellulosic materials like fruit leather. Additionally, a roll-on applicator designed for waterproofing leather products, which may include beeswax, offers a convenient and efficient way to apply non-liquid wax materials for protection against moisture. While the focus of the studies is primarily on leather waterproofing, the principles and components involved, such as beeswax, can be adapted for fruit leather to enhance its shelf life and protect it from moisture damage.
What are the advantages and disadvantages of each type of paint used in construction?3 answersWaterproof paint for construction has the advantages of reasonable material proportion, excellent water resistance, weather resistance, fire resistance, corrosion resistance, and stability. It also has high bonding strength, short curing time, and convenient construction, making it suitable for the protection of concrete structures. The paint construction process using different colors of paint can create special artistic effects, such as resembling the blue sky and white clouds. It also provides good flatness and superior effects compared to water paint, with good environmental performance. Polyurethane building internal wall paint has wear resistance, corrosion resistance, high brightness, favorable flexibility and elasticity, water resistance, mechanical properties, and weather resistance. It is also convenient for construction, non-toxic, and environmentally friendly. Special paint for construction has high weather resistance and alkali resistance, effectively enhances pollution resistance and self-cleaning properties, and is environment-friendly and energy-saving. It satisfies market demands and does not damage the environment or human body. Waterborne paints used for concrete protection are less pollutant and can improve the durability of concrete structures. The permeability of the paint films towards sodium chloride depends on the pore size, with smaller pore sizes correlating with lower permeability.
What are the uses of beeswax?5 answersBeeswax has various uses in skincare, including its role as an occlusive to create a skin barrier, a humectant to lock in hydration, and an emollient to soften and soothe the skin. It has been shown to alleviate symptoms associated with dermatitis, psoriasis, and overgrowth of normal skin flora. Beeswax is also used in the production of candles, shoe polish, vehicle and floor polishes, wax crayons, metal casting and modeling, food processing, and cosmetics. Additionally, beeswax has medicinal effects as an antibiotic and in skin therapy. It is considered effective in the treatment of bruising, inflammation, burns, and has antibacterial properties. Bee products, including beeswax, are also used in cosmetology and dermatology treatments due to their unique therapeutic effects. In summary, beeswax has a wide range of uses in skincare, cosmetics, and various industries, and further studies are warranted to explore its potential benefits.
What to look when forming concrete waterproof agent?5 answersWhen forming a concrete waterproof agent, it is important to consider the raw materials and their proportions. The composition of the agent plays a crucial role in its effectiveness. For example, the use of methanesiliconic acid sodium salt-calcium hydroxide complex solution, sodium silicate, sodium citrate, triethanolamine, hydroxypropyl methyl cellulose, thickening agent 80A51, pectin, JX anti-crack siliceous waterproof agent, aluminum sulfide, tert-Butyldiphenylsilane, and rosinyl hyperbranched epoxy resin can create a cross-linked network structure that provides a slow waterproof effect and allows for crystal growth. Additionally, the inclusion of calcium lignosulphonate powder, alunite, polyoxyethylene fatty alcohol ether, nano silica, sodium fluorosilicate, sodium alkylbenzenesulfonate, lassolatite powder, sodium polyacrylate, sodium methyl silicate, chromium oxide, molasses, sulfur trioxide, calcium phosphate, tetraethyl orthosilicate, phenyl salicylate, calcium hydroxide, perfluorooctyltriethoxysilane, stearic acid, and potassium hydroxide can enhance the waterproofing, water reducing, and leakage resisting effects of the agent. The use of organosilicon polymers, modified through epoxy chloropropane, can create a stable water-repelling film on the surface of the cement, achieving a waterproof effect. Furthermore, the combination of magnesium salt solution with bentonite can create a self-repairing waterproof agent for concrete with excellent waterproof performance and strong self-repairing effect. Finally, the inclusion of illite powder, fly ash, alum, slaked lime, and superphosphate can result in a concrete waterproofing agent with a higher waterproofing rate, making it suitable for various applications.
Can fly ash be used as a waterproofing agent for concrete?5 answersFly ash can be used as a partial substitute for cement in concrete, which can improve its compressive strength and other properties. The addition of fly ash in concrete can increase its strength by up to 28% compared to control concrete. Fly ash can also be used as a binder in high-volume fly ash (HVFA) concrete, where it can replace more than 50% of the cement. However, there is no specific mention of fly ash being used as a waterproofing agent for concrete in the abstracts provided.
