The Holding Magnets Roundt are used in the precast concrete production structures to form free spaces in the work-pieces to fix the concrete inserts. Holding Magnets are used in Magnetic Shuttering System. This equipment type has considerably simplified some production task for the concrete structures producers. It easily gets fixed in the magnet formwork system or on the steel table due to its magnetic properties.
SHINE Holding Magnets offers long term reliability and cost effective solutions for the precast industry. Our products are durable and they last for years under all conditions. With our unique combination of rubber and integrated magnets, you can make almost any shape. Once it´s in place, it stays put. No slipping, no sliding.

The application of talcum powder is extensive, and its physical and chemical performance index requirements are also different. Therefore, Xiao Bian specially organized the nine major applications of talc according to the national standard GB/T 15341-2012 talc and GB/T 15342-2012 talcum powder. Field and physical and chemical performance indicators requirements! 
1. Block talc talc can be divided into cosmetic talc and industrial raw talc according to use.
(1) The block talc cosmetic grade block talc for cosmetics has high quality requirements and strict requirements on physical and chemical properties. For example, there are no sand particles in the ore and there is a sense of lubrication.
(2) Industrial raw materials Talc talc is used to manufacture talc porcelain, refractory bricks and electric discs, and engraving arts and crafts.
2. Talc powder Talc powder is a certain fineness powder product obtained by mechanical addition of talc ore.
(1) Talc powder for cosmetics talcum powder is a high-quality filler for the cosmetics industry, and can be used for various moisturizing powders, beauty powders, talcum powders, and the like. The talc contains a large amount of silicon, which has the function of blocking infrared rays, and can enhance the sunscreen and anti-infrared properties of cosmetics.
(2) Paint-paint talcum powder talcum powder can be used for white body pigments and various water-based, oil-based, resin-based industrial coatings, primers, protective paints, etc. The paint-coating grade talc powder has strong adsorption and is highly dispersed in the oil, which can prevent the paint coating from being precipitated, can also be used as a suspending agent, can also adjust the gloss, prevent the paint coating layer from aging and cracking, and improve the resistance to weathering.
(3) Talc powder for papermaking There are three main uses in the paper industry: fillers, coatings and resin control agents for pulp.
Talc makes the paper firm and white, increases opacity and brightness, and enhances the ability to absorb ink. The talc has a strong fixing force on the pigment, so that the color print has a good color effect. The talc has a very low concave wear value and is therefore very little worn on papermaking equipment and printing equipment.
The talc density is less than that of titanium dioxide (TiO2), which can replace titanium dioxide and reduce production. Talc powder can also be used in the waste paper deinking process to effectively deink the waste paper during flotation and washing.
(4) Talc powder for plastics It can be used as a filler for plastics such as polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene and polyester.
Adding talc to plastic can significantly improve the rigidity and creep resistance, hardness and surface scratch resistance, heat resistance and heat distortion temperature of plastic products. The fineness of talcum powder can also improve the impact strength of plastic products. . The addition of talc to the plastic also has a lubricating effect, which can promote the flow and improve the processing technology of the plastic.
(5) Talc powder for rubber can be used as a rubber filler and a rubber product anti-adhesive agent. Rubber grade talc not only enhances the robustness of the rubber, but also provides additional electrical insulation properties for the rubber product and prevents the rubber product from sticking.
(6) Talc powder for cable can be used for cable rubber reinforcement, cable release agent, etc.
(7) Ceramic talcum powder talcum powder can be used in the manufacture of electric porcelain, radio porcelain, various industrial electric porcelain, architectural ceramics, daily-use ceramics and enamel, etc. It is characterized by high temperature and no discoloration, enhanced whiteness after calcination, uniform density and good gloss. The surface is smooth.
(8) Talc powder for waterproof materials can be used for waterproofing membranes, waterproof coatings, waterproof greases, etc. It can be used as a filling material for roofing products (linoleum, roofing paper, asphalt shingles, roofing panels, etc.) Used as an anti-sticking powder for roofing materials.
When used as a filler, talc acts as a stabilizer in the molten asphalt component, increasing the stability and weathering resistance of the roofing material. When talc is sprayed on the surface of asphalt shingles or rolled roofing materials, it can be prevented from sticking during production and storage.
The waterproofing industry can use low grades of colored and impure coarse ground talc.
(9) General talc powder talcum powder is also used as fillers, release agents, reinforcing agents, etc. for various industrial products.
(10) Talc powder factory inspection project
Talc is an aqueous magnesium silicate mineral with soft properties and good electrical insulation, heat resistance, chemical stability, lubricity, oil absorption, hiding power and mechanical processing properties.
