Description

Ceramic Fiber Blanket is made by continuous processing method. The fiber interweave shapely after being needled. It has excellent tensile strength. The blanket do not contains any bonding agent.

Ceramic Fiber Blanket not only can resist the chemical species, but also the hydrofluoric acid, phosphoric acid and strong base. The Fiber Blanket have excellent capability of resisting the oil. After being dried ,it will repossess the thermal characteristic and the physical feature.

Our needled blanket has various density and thickness so that clients can have many choices. Which will bring the perfect insulating framework and profit.

Q: Working principle, ultrasonic trouble and troubleshooting of ceramic filter: It is based on the action principle of capillary pore and realizes the solid-liquid separation through the capillary action principle of the micropore. Specifically, is the use of microporous ceramic plate water impermeable properties, extraction of ceramic plate and external cavity vacuum pressure, the suspended material groove under the action of the negative pressure adsorption on the ceramic plate, solid material through the porous ceramic plate can not be trapped in a ceramic plate surface, and the liquid due to the hydrophilic effect of vacuum pressure difference and ceramic plate by entering the gas-liquid distribution device, and then discharged or recycled, so as to achieve the purpose of solid-liquid separation.

Q: What are the poor filtration effects of vacuum disc filters?: Under normal circumstances, high vacuum, vacuum suction, high production capacity, filter cake moisture control is good. At present, some ceramic filters are equipped with two or multi-stage vacuum system to obtain almost absolute vacuum, and can reach 0.09 ~ 0.098MPa.

Q: Microporous ceramic filter plate cleaning: Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.

Q: What is the reason that the ceramic filter does not absorb mineral powder?: The recoil pressure is regulated by the pump loop valve and the pressure regulating valve. In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.

Q: Ceramic filter cleaning, sulfuric acid cleaning: Can be washed with chromic acid lotion. The effect is better

Q: What is the reason that ceramic filter does not absorb mineral powder?: There may be a failure of the filtrate pump, the diaphragm of the pump is damaged, and the mechanical seal of the pump is invalid

Q: The vacuum of ceramic filter is not enough: The vacuum degree of ceramic filter is about -0.08MPa, if the ceramic filter is less than 0.06MPa, the vacuum is not enough. If the vacuum of ceramic filter is not enough, it will influence the suction effect of ceramic filter (mainly the thickness of filter cake and water content of filter cake).

Q: What are the functions of honeycomb ceramic filters?: At present, it is widely used in metallurgy, foundry industry, metal melt filtration, using mullite (cordierite) ceramic materials

Q: What are the reasons for the program alarm of ceramic filter?: If that is the ceramic filter tank body of the slurry concentration is diluted, has nothing to do with the ceramic filter itself, can think of ways to enter the ceramic filter tank before the slurry concentration increased, thereby improving the dewatering efficiency of ceramic filter.

Q: Can the ceramic plate filter the hot air?: The cleaning of the ceramic filter is divided into two parts: reverse flushing (also useful gas) and combined cleaning. The purpose of cleaning is to discharge the particles from the hole to the ceramic filter board. Anti flushing and cleaning water filter after direct visual pressure can, generally between 0.08--0.12MPa, such as less than 0.05MPa, while the poor flushing effect without even washing effect, resulting in blocking accumulation eventually led to the ceramic filter plate hole plugging scrap. Replacing the filter element in time and ensuring the water pressure before filtration can provide stable backwashing water pressure. Combined cleaning by ultrasonic vibration, nitrate dissolution method for maximum remove blockage of backwash rushed out, the general ceramic filter every 8 hours of continuous work should stop cleaning 1 hours, such as the use of the old plate or the suction effect is poor, can strengthen cleaning (such as shorten the cleaning period, prolong the period of cleaning, increase the amount of nitric acid etc.). Other reasons such as 1,2,3 are normal, but can not be discharged from the spindle speed too fast, even the ceramic filter itself manufacturing defects, the user equipment modification and so on, are likely to lead to abnormal operation of equipment. We specialize in ceramic filter boards for many years and welcome exchanges.
