Sandwich Board is a kind of light-weight fire-proof decoration wall board both for indoor & outdoor, having colorful solid rock grain, and the feature of fire-proof, water-proof, weather endurance.

Sandwich wall board is widely used for inner and outer wall decoration in residential buildings, office buildings, mansions, restaurants, hotels, coffee shops and all sorts of business sites. Indeed, it is the most fashion material for decoration in modern times.

Q:What is the filtration accuracy of 50nm ceramic membrane?: It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.

Q:Ceramic filter capacity.: 60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.

Q:The ceramic filter plate is broken. What will happen to the vacuum pump?: If it is found that the ceramic plate is broken, it should stop in time to replace the broken ceramic plate. Ceramic filter is produced by vacuum suction vacuum pump to the pulp in the water through the ceramic plate away, the surface aperture ceramic plate for several microns, so it can intercept the cake on the ceramic plate on the surface, if the ceramic plate is broken, a hole is a few millimeters, when the vacuum suction pump when they go together along with the pulp pump.

Q:What are the functions of honeycomb ceramic filters?: High quality and high density straight hole mesh, the product has high heat resistance and impact resistance properties of cast high fever temperature, design straight hole to guarantee the balance between strength and flow, effectively remove impurities and slag particles, the mechanical properties of casting, the surface quality and the qualified rate of products is greatly improved.

Q:Principle of chemical engineering drum vacuum filter, the faster the speed, the less the amount of filtrate obtained per turn, the more the amount of filtrate obtained per unit time?: In unit time, the more turns of the drum, the greater the centrifugal force, the greater the rate of filtration in unit time, that is to say, the amount of filtrate in unit time is moreRotating drum vacuum filter, the greater the speed, the greater the filtration rate, but the shorter the time each turn, the amount of each filtrate will be reduced

Q:Can the plate filter press pass through the filter plate?: There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.

Q:The working principle of ceramic filter: The working principle and mechanism and the shape of ceramic filter disk vacuum filter is similar to that in the pressure under the action of suspension by filtration medium, particles are trapped cake is formed at the surface of the medium, and the liquid through a filter medium outflow, reached the purpose of solid-liquid separation. The difference is that the filter medium of ceramic filter plate with microporous capillary effect, the capillary force in the pores is larger than the vacuum force applied to microporous keep full liquid state, no matter under what circumstances, the ceramic filter plate does not allow air through, because there is no air through solid-liquid separation, low energy consumption, vacuum a high degree of.

Q:What is the backwashing pressure of the ceramic filter?: The working process of ceramic filter is: suction - drying - unloading - backwash - suction - drying - unloading - backwash...... In circulation, suction, the drying process is to make the slurry liquid by vacuum suction and capillary effect (usually water) through the filter media from the left, the filter cake on the filter medium (the two processes like syringe pumping), and then through the scraper discharge, after unloading, ceramic filter machine is complete a cycle in the absorption slurry, drying process, some fine particles may enter the filter medium or stacked on the surface (a lot of pipeline internal filtration medium ceramic filter plate), these small particles blockage will make the filter medium permeability and filtering effect of the loss from the poor, in order to reduce the possibility of blockage ceramic filter, will enter the backwash (this process is like a water jet injector). Ceramic filter backwash is through the pressure of water, these small particles plug discharge ceramic filter board.

Q:How should the static and dynamic sealing points of the ceramic filter be leaking?: When the ceramic filter works, the operation may be as follows: 1. The feed is injected and the pulp is injected into the tank of the ceramic filter. 2, mixing system, ceramic filter stirring rake back and forth mixing, driven by mixing reducer. 3, spindle rotation, material level reached a certain range, through the spindle speed machine to drive the ceramic filter disk rotation.

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.
