Glass bubble,Hollow glass microspheres , Glass sphere beads, Manufacturer & suppliers

Sinosteel Maanshan Mining Research Institute Co., Ltd. updated the review status of listing application on December 19, and the company’s IPO application has been accepted.

Tongbi Finance and Economics learned that the company’s predecessor, “Research Institute of Ferrous Metallurgical Mines of the Ministry of Metallurgical Industry”, was founded in 1963 and was a key scientific research institute directly under the former Ministry of Metallurgical Industry. The company has long been engaged in professional services for comprehensive utilization of mineral resources, providing customers with technical services and technical engineering services in mining, mineral processing, rock and soil, mine safety and environmental protection, etc; At the same time, the company pays attention to the technical research and development of new materials such as hollow glass beads, new mining curing materials, carbon aerogel, spherical weighting materials, and realizes the industrial mass production of hollow glass beads.

The State Council and various ministries and commissions have successively issued a series of policies, including the “cornerstone plan”, committed to ensuring the supply security of national strategic mineral resources. With the support of the above national strategies and industrial policies, the industry of comprehensive utilization of mineral resources has broad development space. With the progress of product technology and application technology, hollow glass beads are more widely used in more downstream industries, and the application field will be further expanded in the future. For example, in the field of new energy vehicles, hollow glass beads are used as filling materials to reduce the density and weight of adhesives and interior and exterior trims, achieve lightweight vehicles, improve the physical and chemical properties of adhesives and interior and exterior trims, and improve production efficiency. With the increasing demand of new energy vehicles for lightweight and improving production efficiency, hollow glass bead products are expected to be more widely used in the future. In addition, with the continuous emergence of emerging industries and the continuous development of traditional industries, hollow glass bead products will expand more application fields.

In recent years, the development and utilization intensity of China’s mineral resources has rapidly improved, mining and dressing technology and equipment have made continuous progress, and the comprehensive utilization level has greatly improved. In addition, at present, entrepreneurs all over the country are very optimistic about the development prospects of the sand and gravel industry and the business opportunities for the development and utilization of mineral resources, and have invested in the construction of large and medium-sized sand and gravel production bases. At the same time, major state-owned enterprises and domestic large cement enterprise groups have begun to set foot in and layout the sand and gravel aggregate industry according to the industry development trend. Their involvement has injected new development impetus into the development of the sand and gravel industry and become a new force to promote the high-quality and high-level development of the sand and gravel industry.

Opening ceremony of Advanced Powder Material Industrial Park of Sinosteel Mining Institute was held

Yuan Fang and Liu Guowang attended

In the afternoon of November 29, the opening ceremony of the Advanced Powder Materials Industrial Park of Sinosteel Mining Institute was held in the municipal economic development zone. Yuan Fang and Qin Junfeng, municipal leaders, Liu Guowang and Xu Chuanhua, leaders of Sinosteel Group, and Wang Qiang, secretary-general of the municipal government attended the opening ceremony.

It is reported that the advanced powder material industrial park project of Sinosteel Mining Institute was constructed by Maanshan New Material Technology Co., Ltd. of Sinosteel Group with an investment of 2 billion yuan. The project is divided into two phases. In the first phase, three carbon aerogel production lines, two high-performance hollow glass beads production lines, and one spherical weighting material production line will be constructed. After reaching the capacity, the project can produce 1000 tons of carbon aerogel, 15000 tons of high-performance hollow glass microsphere, and 20000 tons of spherical weighting materials annually. It is expected to achieve an annual output value of 1 billion yuan and an annual tax of 60 million yuan.

The first phase of the project was started in October 2021. At present, the main plant has been completed, the equipment has been installed and commissioned, and is in trial production. It will be formally put into production before the end of the year.

Hollow glass microspheres ( also known as glass bubbles ) are hollow glass spheres made of chemically stable Soda-lime-borosilicate glass with thin walls(wall thickness 1~3.5μm). We have several grades available with true density ranging from 0.20g/cc~0.60g/cc, Sinosteel hollow glass microspheres can be used as lightweight functional additives for Composites,Thermal insulation paints/coatings, Sealant/adhesives, Low density cementing slurries and many more applications with very competitive quality and price.

Sinosteel Maanshan New Material Technology Co., Ltd., a wholly owned subsidiary of Sinosteel Maanshan Institute of Mining Research Co. Ltd., is a comprehensive high-tech company that specializes in research&development 、production and sales of high-performance Hollow Glass Microspheres.

Established in 1963, Sinosteel Maanshan Institute of Mining Research Co., Ltd (Hereafter, The Institute) used to be a key scientific research institute under the former Ministry of Metallurgical Industry. The Institute has been authorized to grant master’s degree (first-level discipline) by the Academic Degree Committee of the State Council since early times. The Institute, now as a national innovation-oriented company and a key high-tech company under the National Torch Program, is attached to Sinosteel Group Corporation Limited. The Institute has undertaken and completed a number of major national science and technology projects successfully, and won more than 680 awards of scientific and technological achievements at national or provincial levels by far.

Single From a cost perspective, if the hollow glass bubbles per unit mass of the same price, you should use the lowest possible density of hollow glass microspheres, so low unit cost.If just from a performance standpoint, because the larger the lower the density of the hollow glass microspheres diameter, large diameter also reduces the conductivity between the zinc coating, which reduces the resistance to salt spray paint, and therefore should be chosen particle size as small as hollow glass microspheres.There are on the one hand I must mention that, due to the formulation of other fillers such as zinc and iron phosphate high density, when the coating solution is stirred crashed hollow glass microspheres, and in the spray when a low intensity hollow glass microspheres are easily broken failure. Therefore, the density of the microspheres can not be selected too large, the particle size can not be too large, and the strength is sufficient.

Proposal to add the following methods:
In order to take full advantage of the characteristics of the hollow microspheres, recommended adding a last resort, that is added to the beads into the final as low speed mixing equipment dispersed using low shear force, because the spherical beads mobility well, between the friction is not large, so it is easy to disperse. You can complete a short wet, slightly extended mixing time to achieve uniform dispersion.
Beads chemically inert, non-toxic. However, because of a very light, so they need special attention added.Recommended stepwise addition method, which is the amount for each remaining 1/2 beads gradually added, this can be good to avoid beads float into the air and dispersed more complete.
