What is microsphere glass hollow? Hollow glass beads are specially processed glass beads with smaller density and worse thermal conductivity than glass beads. Hollow glass beads have high compressive strength, high melting point, high resistivity, thermal conductivity coefficient and small thermal shrinkage coefficient. They are known as the "space age material" in the 21st century. Hollow glass beads have obvious weight and sound insulation effect, make products have good crack resistance and reprocessing performance, and are widely used in engineering plastics, anti-corrosion insulation materials, rubber, buoyancy materials, FRP, artificial marble, artificial agate, wood composite materials and petroleum industry, aerospace, 5G communication, new high-speed train, ships, heat insulation coatings, adhesives effectively promote the development of science and technology in our country.
Product features of hollow glass beads: Hollow glass beads colour pure white is widely used in any product with appearance colour requirements; the density of hollow glass beads is about one-tenth of the traditional filling particle density after filling can greatly reduce the base weight of the product, replace and save more production resin, reduce the product cost; hollow glass beads wetting dispersion easy can be filled in most thermosetting, thermoplastic resin, such as polyester, epoxy resin, polyurethane. Because hollow glass beads are small balls in liquid resin than sheets, needles or irregularly shaped packing, the filling performance is excellent. More importantly, the small beads are isotropic, so it will not cause the orientation of different parts of the contraction rate to be inconsistent, ensuring that the size of the product is stable and will not warp. The interior of the hollow glass beads is thin gas, so it has sound insulation characteristics, and heat insulation is an excellent filler for various thermal insulation and sound insulation products. The heat insulation characteristics of hollow glass beads can also be used to protect against the heat shock caused by the alternating changes between hot and cold conditions. High specific resistance and very low water absorption rate make it widely used in the processing and production cable insulation materials. The particles of the sphere determine the minimum specific surface area and low oil absorption rate, and the amount of resin can be greatly reduced in the use process. The viscosity will not increase much even under the premise of high addition amount, which greatly improves the production and operation conditions and can improve the production efficiency by 10%~20%. The main uses of microspheres are glass hollow. The spherical structure of hollow glass beads makes good dispersion of the impact force and stress, Can reduce the stress cracking caused by thermal expansion and cold contraction of the coating; White powder of hollow glass beads has a better whitening effect than ordinary pigments, Can effectively reduce the amount of other expensive fillers and pigments; The low oil absorption characteristic of glass beads enables more resins to participate in film formation, So that the adhesion of the coating progress 3~4 times; The addition of 5% microbeads brings the coating density from 1.30 to below 1.0, Thus greatly reducing the coating weight, Prevent the appearance of the wall coating zero-fluctuation phenomenon; Microbeads have a good reflective effect on ultraviolet light, Avoid coating yellow and aging; High melting point of the microbeads, Greatly improve the temperature resistance of the coatings, Play a very good role in fire prevention; The spherical particles can act as a bearing, Small friction force, Can strengthen the movable coating properties of the coating, The construction is much more convenient.
