Sodium silicate dissolve drum

6.4 the material process

佰富彩Melting process is after the water quenching glass material, with a belt machine into the cylinder, according to certain material, water, add water, under the heat pressure dissolved into a qualified water glass. At present in roller material is given priority to.

6.4.1 control condition

A join drum material such as water in the table below:

佰富彩The ratio of the project

(1.381 Kg/m3, Kg) 1.526 Kg/m3 1.629 Kg/m3

佰富彩56 ° 40 ° Be ° 50 'Be' Be '

Feed water 37 50 + 50 + 63 + 45 to 55

佰富彩B steam pressure of 0.30-0.50 MPa

C water temperature of 95 ℃ or less (as high as possible)

If use caustic soda modulation products of different modulus, use the type of calculation to join the number of caustic soda.

佰富彩0.996 * b - M * a

M =

佰富彩0.775 * M * a1

Type:

佰富彩A. as a raw material Na20 percentage content of sodium silicate products

A1 is caustic soda content

佰富彩The percentage of b as the raw material of sodium silicate SiO2

M for the product of the modulus of sodium silicate products

M is 1 tons of sodium silicate solid need with addition of the number of caustic soda; Tons of

The proportion of calculated according to the baume degree of caustic soda caustic soda, determined to join the volume of caustic soda. Give us water vapor is calculated to determine the addition amount of water.

佰富彩Liquid products and caustic soda modulation module with reference to the above formula.

佰富彩6.4.2 operation

佰富彩A. check the drum machine is normal.

B. according to the production of different concentrations of sodium silicate in accordance with the requirements of different specifications to add material, water than inside the drum.

佰富彩C. in steam heating roller, roller pressure control in 0.3 0.5 MPa, after reaching pressure, close the steam valve.

佰富彩D. often measured concentration inside the drum materials, such as the concentration of the material is not enough, continue to turn the drum, until achieve concentration, if inside the drum material after all, still can not meet the prescribed concentration, by the operators in the next add some material, make the concentration is high, the mixing, until qualified. And vice versa.

E. of qualified products, start feeding, feeding before check intermediate slot for material stock, in order to avoid not fit after feeding material overflow caused by accidents.

佰富彩F. when feeding stop first, then play to open the valve, until completion of the feeding.

G. roller feeding in a gas-liquid separator, first enter the workshop finished pot, the workshop after application through qualitative analysis into the shipping department.

佰富彩6.4.3 matters needing attention

佰富彩A. in steam pipe pressure gauge, must be in good condition, if the pressure gauge failure to timely replacement.

B. when confirm there is no pressure in the cylinder, can open feeding cover.

佰富彩C. feeding cover screw must be complete, each material must tighten the cover.

佰富彩D. check internal junction material of drum, junction material, cleaning roller, then put into use.

E. prevent feeding pipe blockage, feeding tube bending clearance, should check the cut-off valve, to ensure the valves complete, safe and reliable.

F. parking maintenance or overhaul, the roller clean.
