Product introduction:

The talcum powder is called PULVISTALCI in English. It is white or white like, fine and non abrasive powder. It feels oily. Odorless, tasteless. This product is insoluble in water, dilute ore acid or dilute hydrogen oxidizing alkali solution. It can be used as medicine.

Commodity Description:Talc is mainly composed of talc containing magnesium silicate and its molecular formula is Mg3[Si4O10] (OH) 2. The monoclinic system of the genus talcum. Crystal is false six square or rhombus flake, even see. They are usually dense, massive, leaf like, radial, fibrous aggregates. Colorless, transparent or white, but light green, light yellow, light brown or even light red due to a small amount of impurities, and a pearl luster on the cleavage surface. The hardness is 1, and the proportion is 2.7~2.8.

Main features: the talcum has good physical and chemical properties such as lubricity, anti viscosity, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good covering power, soft, glossy, and strong adsorbability. Because the crystalline structure of talcum is layered, it has a tendency to split into scales easily. And special smoothness, if Fe2O3 content is high, it will reduce its insulation.

Product classification:

The physical and chemical properties of talcum powder are divided into three grades: superior quality, first grade and qualified product.

3.3 specifications

3.3.1 fine talcum powder is divided into two specifications according to its fineness and passing rate of screen.

The A. fineness is 45 m, expressed as the weight percentage of the product through screen.

The B. fineness is 75 m, expressed as the weight percent of the product through the screen.

3.3.2 fine talcum powder is expressed in terms of its particle size distribution and particle size, with cumulative percentage of products less than 20, 10, 5 and 2 m.

3.4 product markup

3.4.1 product labels for talcum powder are expressed in the following ways:

3.4.2 markup example

1: grade talc powder with a whiteness of 75% and fineness of 45 m with a pass rate of 98%.

Talcum powder TL75-45-98GB

For example, 2: whiteness 80%, particle size less than 20 m, and the cumulative talcum powder content greater than 85%.

Talcum powder WF80-20-85GB

Case 3: rubber grade talc powder with a fineness of 75 m and a pass rate of 99.9%

Talcum powder AJ75-99.9GB

Technical requirements for cable grade talcum powder

The physical and chemical properties of cable grade talcum powder should meet the requirements of table 8.
