Products induction
Acid washing quartz sand is wet pickling, using a variety of acids. Such as hydrochloric acid, sulfuric acid, oxalic acid, hydrofluoric acid and so on


Principle
Crushing before pickling is broken by wet method, part of which is using mechanical method, such as hammer breaking, broken, so that the broken material contains a large number of mechanical iron. Mechanical iron and quartz sand react slowly in water, usually after a few days will also mechanical iron oxidation into ferric iron into red yellow. If immersed in acid, iron is oxidized faster in exposed air.

Quartz sand---water washing--separate---acid leaching---water washing---dewatering---drying

After the quartz sand is broken and washed, some impurities can be removed. Magnetic separation can remove more than 99% of the mechanical iron. Acid leaching can add various acids according to the actual situation. Acid leaching equipment must be resistant to acid and alkali plastic container, stainless steel is not recommended. Partial acid corrosion of stainless steel. For acid leaching, it is recommended to use reactors or containers with heating and mixing. Make the acid leaching more thorough and more responsive. Washing should also be stirred, cleaned thoroughly.


Advantage:
Difference between pickling quartz and common quartz.
Pure different, acid washed quartz sand is higher than that of ordinary quartz sand silica purity, pickling quartz sand, also known as fine quartz sand, SiO2 and SiO2 was 99.7%; ordinary quartz sand is 94%.

Pickling quartz sand will need to go through complex, magnetic separation, flotation, leaching, purification and complex process can get pure quartz sand gravel, while the ordinary quartz sand would not go miscellaneous. That is to say the number of the purification, the higher the degree of pure sand.

Different colors, acid washed quartz sand color is pure white or colorless transparent color, can be used for glass, ceramic, steel casting, rubber, paint, paint, water treatment industry and so on; and the ordinary quartz sand was pale yellow, pale yellow appearance will be coated, generally used for sewage treatment, artificial floor etc

The service life does not need, the acid washing quartz sand generally may use three to five year time to be possible to use safely; but ordinary quartz sand may use for one year to two years must change once, otherwise its water quality processing effect is inferior to formerly good

The main purpose and benefits of acid washing quartz sand filter material: pickling is to use carrier 6mol/L hydrochloric acid immersion boiling 2H or concentrated hydrochloric acid heating, dipping and boiling 30min, filtering, washing to neutral, drying. Pickling can remove iron and aluminum on the surface; in general, it removes impurities. No matter whether it's used for water treatment, filtration or anything else, there is no impurity



Work process: 

The process of washing quartz sand filter material is as follow:
Usually factory worker hand picking the quartz stone.
and then the quality of quartz ore determines the hydrochloric acid concentration and immersion time.
The next is broken, and now the quartz sand production equipment are integrated, the ore into the device is out of the finished product. But acid washed quartz sand is not suitable for this kind of equipment, because the ore can not be directly broken into the vibrating screen, but to enter the acid pool, so it is not suitable for integrated equipment.

Hydrochloric acid concentration is generally about 30%, soaking time is good at about 24 hours. After soaking quartz sand has no impurities, and the color becomes crystal clear white, after screening and washing, screening and washing in a set of equipment completed once. The quartz sand produced in this way is good for reverse osmosis and desalted water equipment.

5The main purpose and benefits of acid washing quartz sand filter material: pickling is to use carrier 6mol/L hydrochloric acid immersion boiling 2H or concentrated hydrochloric acid heating, dipping and boiling 30min, filtering, washing to neutral, drying. Pickling can remove iron and aluminum on the surface; in general, it removes impurities. No matter whether it's used for water treatment, filtration or anything else, there is no impurity!
