Product Description:

Zircon Sand and Zircon Powder High Performafce for Refractory Use

1.Structure of Zircon Sand and Zircon Powder

We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. Zircon is a remarkable mineral, if only for its almost ubiquitous presence in the crust of Earth. It occurs in igneous rocks as primary crystallization products, in metamorphic rocks and in sedimentary rocks as detrital grains. 
Further, the mineral due to hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.

2.Main Features of Zircon Sand and Zircon Powder

1 Tiny, round, solid ball shape provides greater surface area for improved performance and dispersion in its application

2 High refractory rating, lower specific gravity rating, and higher service temperature produces greater yield

3 With lower bulk density, it offers better air permeability for better performance as a result of its overall physical characteristics


3.Main usage of Zircon Sand and Zircon Powder

1. The 80-120M zircon sand is used in investment casting, the processing is called dipping. 
2. It can enhance the shell`s thickness. 
3. It is specialize used in inner layer being mixed with silica sol.

Q:What's the refractoriness and how to measure the refractoriness?
Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
Q:Who knows what kind of fire protection material is better?
Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)
Q:What are the classifications of refractory? Which category does steel ladle castable belong to?
In addition, it can be divided into refractory, shapeless refractory material. And it can also be divided into acidic refractory, basic refractory and neutral refractory. If you want to know more, you can ask thme. In fact, every company has different refractory clasifications. There are more clasifications in Huaheng.
Q:Is it normal for caable fire resistant material to catch on fire?
Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Keypoints; 1, curtain wall design must consider the safety requirements, one of which is fire protection design. 2, Generally, fire protection planning between curtain walls should use the method of setting fireproof isolation layer. 3, Two layers of fireproof isolation layer whose thickness should not be less than 100mm respectively on the top edge and lower edge of the material parts of the house. 4, the fireproof isolation layer commonly uses 1.5mm thick galvanized steel sheet as supporting plate, using for shelving fireproof sheet. The 100mm thick cavity between the layers is filled with mineral wool non-combustible materials tightly covered with tinfoil on the surfaces. 5, protective isolation layer should try to reconcile curtain wall beam level and finish floor level, so as to fill non-combustible material and to avoid that a piece of glass acrosses two fire compartments. 6, the beam should be inside 100mm thick fireproof isolation layer to protect the beam and the upper curtain wall plate. 7, when there are open fire function areas like large-scale hotel or restaurant kitchen inside the curtain walls, curtain wall glass in these parts should consider using cesium potassium fireproof glass to improve the fireproof rating in the region. 8, Fireproof setting in the around areas of curtain wall can use the same method of the above fireproof setting between layers. The joint parts of fireproof isolaton layer and main part as well as curtain wall should use fireproof sealant to seal.
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
Q:Does anyone know the difference between refractory and thermal insulation material?
The main difference between insulation bricks and refractory bricks are as follows: 1. Insulation effect The heat conductivity cofficient of insulation bricks is usually 0.2-0.4 (average temperature of 350 ± 25 ℃) w / mk while the heat conductivity coefficient of refractory bricks is 1.0 (average temperature of 350 ± 25 ℃) w / mk or more. Thus it can be seen that the insulation effect of insulation bricks is much better than that of refractory bricks. 2. Refractoriness The refractoriness of insulation bricks is generally below 1,400 degrees centigrade while the refractoriness of refractory bricks is above 1,400 degrees centigrade. 3. Density Insulation bricks are generally light-weight insulation material, and the density is generally 0.8-1.0g / cm3. But the density of refractory bricks is above 2.0g / cm3.
Q:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
Common red brick and refractory brick.
Q:How to hang the suspended brick in the refractory masonry?
First you can weld the metal fastener of the suspended brick and then hang up the brick.
