Glass fiber reinforced plastic containing silicon is recommended.
Purification tower body is made from glass fiber reinforced plastic which is composed of resin and glass fiber cloth by curring. Resin with strong resistance can be found with the help of medium concentration and temperature, then it will be fine.
In general, glass?reinforced?plastics can be used for producing chromic acid waste gas purification recoverer device. Glass reinforced materials, namely glass fiber reinforced materials, has many advantages such as light weight, high strength, anticorrosion, thermal insulation, insulation, noise insulation and so on. Glass?reinforced?plastics doors and windows use glass fiber twistless roving and its fabric as reinforcing material and unsaturated resin as matrix material, and composite these two material by a special process add other mineral filler. After adding other mineral filler, various hollow sections are processed into the products by heating and curing. Generally speaking, the main characteristics of glass?reinforced?plastics doors and windows are: aging resistance and high strength. Glass fiber reinforced plastic without steel plate as the lining does not need any monomer auxiliary enhancement material, depending completely on its own to support the whole structure. Due to the glass fiber and its fabric as reinforcing material, without filament resin bonding bare, by mechanical thermal curing pultrusion molding, so it features with fracture resistance, anti-bending and deformation resistance. It also is corrosion resistance and has a long life. Glass fiber reinforced plasticbelongs to high quality composite material.
Rated condition is 2. * filtering grid should be cleaned regularly according to the degree of pollution. * according to different air volume. There are two types including vertical network format and horizontal network format. * Airflow direction of horizontal recycle collector is from right into the left, and chromic acid waste gas purification recoverer is mainly used for recycling and purifying chromic acid waste gas from electroplate chromate tank belt. * the bottom must be maintained at a level of 5 meters. *Face velocity passed through recoverer filter net must be maintained at 2 to 3 meters per second so that chromic acid can be expelled from bottom hole with efficency is over 90% and chromic acid liquid is recycled. * All air duct system before the recoverer is made from plastic plate. The chromic acid can be directly poured into the plating bath with the airflow direction cannot be reversed. The airflow direction of vertical collector is from bottom to top and it should be used together with BF4-72 type centrifugal ventilation machine. It can be cleaned once a month.
