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
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.
