Slag ball content analyzer

First, the use of slag ball content

in accordance with

GB/T5480.5-2008

Mineral wool and its products test method Standard design of slag ball content, can analyze the slag ball content of glass wool and its products, slag wool, rock wool, its products, aluminum silicate cotton and its products. It has the characteristics of small size, beautiful appearance and practicality, and is an essential instrument in the laboratory.

Steps for usage

1,

Preparation sample

press

GB/T5480.5-2004

The selection of the pattern, cut the full thickness of the sample

11g

about. In the case of glass wool and its products, at (

500±20

)

°C

Burning

30min

Above; for silicate cotton and its products, at (

700±20

)

°C

Burning

30min

the above. Remove the binder and weigh it accurately

0.01g

. The number of samples shall be as specified in the product standard, but shall not be less than

3

One.

2,

Press sample

The weighed sample is placed in the corresponding sample cylinder and placed on the press for manual screw press.

3,

Wetting sample

Take out the pressed sample and put it on

250mL

Adding a surfactant solution to the measuring cup

50mL

And stir well to allow the fibers to wet and disperse in solution.

4,

Separation test

Move all of the sample into the separation barrel.

Turn on the water switch to make the flow rate of the rotameter

60mL/min

This flow is maintained until the fibers are dispersed and suspended in the water.

Increase water flow to (

120-180

)

mL/min

, continue to separate

10min

about.

After the water in the separation cylinder is clarified, the slag discharge valve at the lower end of the separation cylinder is opened, and the slag ball is completely discharged into the standard sieve whose side length is not longer than the side length of the sieve hole specified by the product standard by means of the water flow.

Check if the fibers in the fiber collector contain slag balls. If there are slag balls, they should be placed in the separator for separation.

5,

dry

Put the sieve containing the slag ball into the electric drying oven, at

105-110

)

°C

Dry at least at temperature

20min

.

6,

Screening

Move the dried slag ball into the standard sieve of the sieve specified in the product standard, and add

3

Only the diameter is (

20±1

)

Mm

Ceramic ball, after being covered, start the sieve screening machine

15min

.

7,

Weighing

The sieved slag balls are weighed on a balance and the readings are accurate.
