How does the float glass production process prevent mildew?

February 15, 2020

[China Glass Net] Glass mold has always been an industrial problem. The glass mold (ie, anti-alkali) chemical reaction, changing the surface properties of the glass. Under the sunlight, there are rainbow, mildew, watermark, mime, and paper on the surface. And so on.

The moldy of glass appears in the process of production, storage and transportation. The surface of the glass products after moldy will lose its luster, lose transparency, and appear rainbow, white spots or patch phenomenon (not easy to separate), which seriously affects the quality of float glass products, resulting in The image of glass companies in downstream customers has been greatly reduced, which has affected the price of finished products. Especially in the current sluggish market of glass sales, the important measure to keep the company strong in competition is to further improve the quality of the glass, greatly reduce the scrap rate caused by mold and reduce the production cost.

Therefore, it is especially important to choose a good mildewproof product. At present, the moldy protection of glass mainly includes three kinds of mold-proof powder, mildewproof, anti-mildew, anti-mildew and anti-mildew. Among the three types of products, the mildewproof powder is superior, and it is a nano-scale polymer material, which is environmentally friendly, highly efficient, and easy to clean. Among them, imported mildewproof powder has been paid attention to by glass enterprises because of its high-quality materials and strict production requirements. However, its high price makes glass companies daunting and the cost increases seriously, which is no longer suitable for the current enterprises to advocate cost-saving needs. In recent years, the rise of domestic anti-mildew powder is making up for this deficiency, and the price only accounts for 1/3 of the imported powder. The quality of some of the company's products has reached or even exceeded the international level, which fully meets the production needs of domestic glass enterprises. As the added value of glass products is getting higher and higher, the use of mildewproof products is receiving more and more attention. In response to the development of the glass for the high-end glass market, a new generation of "coconut" anti-mildew products has emerged, which greatly improves the effect of glass mold-proof isolation and cleaning. At present, such coconut shell anti-mold products have been successfully developed by Gree Technology Co., Ltd., which owns the independent intellectual property rights of anti-mold powder, and gradually promoted to high-end glass production enterprises. For the anti-mildew paper, although the operation is simple, the anti-mildew effect is excellent, and it can be recycled, but it is gradually replaced by the powder product because of its disadvantages such as high use cost and long standing time, which may cause paper printing. The anti-mildew products are still not mature enough, the market usage rate is not high, and the long time is easy to cause the cleaning to be unclean.

  Polyester Fabric is a gorgeous fabric that offers outstanding durability, insulation, and wrinkle resistance. Without getting too in-depth with the science of it, the material is crafted from the combination of carboxylic acid and alcohol. The chemical reaction forms polyester in a molten form, which then cools, becomes brittle and is cut into tiny chips. These chips are melted and placed in a funnel-like contraption called a spinneret, which feeds the molten chips through its narrow holes at the bottom, then presses and spins them into a single strand, forming the polyester yarn to be woven into cloth. At Mood, our refined collection of Woven Polyester Fabric is perfect for outdoor wear, jackets, suits, and dresses, bedding set.

  Characteristics and uses of polyester fiber
  Strength: The strength of polyester fiber is nearly 1 times higher than that of cotton and 3 times higher than that of wool. Therefore, polyester fabric is strong and durable.
  Heat resistance: It can be used at 70~1700C, which is the best heat resistance and thermal stability of synthetic fibers.
  Elasticity: The elasticity of polyester is close to wool, the wrinkle resistance is higher than other fibers, the fabric is not wrinkled, and the maintenance is good.
  Abrasion resistance: Polyester's wear resistance is second only to nylon, ranking second in synthetic fiber.
  Water absorption: Polyester has low moisture absorption rate and good insulation performance, but due to low water absorption, the static electricity generated by friction is large and the dyeing performance is poor.
  As a fiber for clothing, polyester has a wrinkle-free and non-ironing effect after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., and is widely used in various clothing materials and decorative materials. Polyester is industrially used for conveyor belts, tents, canvas, cables, fishing nets, etc., especially for polyester cords for tires, which are close to nylon in performance. Polyester can also be used for electrical insulation materials, acid-resistant filter cloths, and pharmaceutical industry fabrics. Synthetic fiber has been widely used in various fields of the national economy because of its high strength, wear resistance, acid resistance, alkali resistance, high temperature resistance, light weight, warmth, good electrical insulation and no fear of mildew.
