production technology and operating techniques 

First, strict process control indicators, process indicators here 

Operation. 

Preparation of 311 lye 

Preparation of qualified, clear acid, dilute alkali. 

312 glue 

Gel temperature, PH value and quality silica gel a distance of 

Amount of key factors. Good quality glue, plastic bubble to avoid, reduce 

Breakage rate. 

313 acid bubble 

Low concentration of acid or acid soak a short time will have white plastic foam, but also 

Not too high too long. Pore ?silica gel than coarse bubble concentrations were slightly acid 

High. 

314 washed 

Washing temperature, washing speed and washed way. wide pore granular silica gel than 

 Narrow Pore Granular Silica Gel washing temperatures are high, even through the water cycle to wash. 

Can not let the wet glue prolonged exposure to air, plastic can not be washed 

And other media contacts. 

315 Dry 

Drying temperature, humidity and speed of drying silica gel breaking 

Yellow broken rate and the reasons for cold and hot easily broken, high temperatures and easy 

Yellow. 

4 Equipment 

411 lye advanced filtration equipment to prepare qualified clear lye. 

412 glue nozzle, spray to disperse the eye, the angle appropriate to reduce the particles 

Adhesion, pressure and pH control the amount of spray to keep the eye open. 

413 receiver, washing tank internal corrosion to cross the border to avoid the red 

Gel. 

 

414 with acid tank valve should be sealed, otherwise the acid to leak out of plastic pipes and 

Will produce a white plastic washing tank. 

415 cars are drying oils, plates rust, will have red plastic. To be approved 

Regular replacement of the plate, preferably stainless steel plate or stainless steel mesh belt. 

5 Discussion 

Silica Gel is very squeamish, the production processes of any kind 

Changes in the quality of silica gel will have some impact, and therefore 

Strict control of process indicators, standardized technique. 

Use high purity quartz sand and soda ash as raw materials to produce high-quality silicone 

Sodium, and kiln furnace to be advanced. Strict control of sodium silicate and sulfuric acid 

The oxide content. Preparation of the advanced equipment used clear filtering 

Lye. Stainless steel mesh belt drying, silica gel can not only improve the quality 

Volume, but also reduce labor intensity. 

To train a number of excellent technology, strong sense of responsibility operatives, Yan 

Conditions control the grid by each fixed point, every good pass, 

To produce high quality silica gel.
