Filterglass netlike for foundry

During the manufacture of casting, due to some reasons, when cast steel, iron, aluminum and other metal castings, it is easily to meet the quality problems, such as arising slag hole, sand hole, gas hole, etc. Thereby, it has high technical value and economic value to remove the non-metal material from the metal material, so that promoting the rate of casting finished products, and casting quality either.

The filtering net for foundry produced by our company are manufactured with resistant-high-temperature fiber, further more, they are produced by special technique and following-process, so with special technology and stable quality, the products of our company have been systematically.

Compared to other kinds of net for casting filter, the resistant-high-temperature fiberglass netlike for foundry is with lower quotation, higher ability of filtering residue and lower gas arising, thus it is easy to use and could keep the element of metal steadily; what is more, these products have good performance on high temperature resistant, flame resistant, good chemical stability and intensity of steel. Thereby, this kind of filtering netlike cloth is the favorable filtering material for various metal-water. It could be used on chemical liquid filtering and high-temperature gas filtering either.

Resistant-high-temperature fiberglass netlike for foundry are widely used to filter and purge all kinds of metal-water, by using our products, it could get the next aims:

Effectively get rid of the blister, oxide with dust and such kind of impurity in metal-water, by this to erase the residue hole, sand hole, gas hole of the casting ultimately, so that improve the inside and blanket quality of the casting, the finished-products either.
Improve the mechanical ability of casting: increasing the stiffness of casting, further more, the blanket becomes more homogeneous and strength of resisting bend has improved.
Change the carbon form of casting, in order to decrease the size of carbon, reduce the thickness and make the figure flexuous slightly.
Alter the mechanical manufacture capability of casting, improve the efficiency of processing.

Main products: Aluminum-water filtration, Steel-water filtration, Iron-water filtration, Copper-water filtration, Cap-filter net, etc. the main mesh size are: 1.0x1.0, 1.2x1.2, 1.5x1.5, 2.0x2.0, 2.5x2.5, etc. We could make products of special gauge to satisfy customers’ order, either. More and more joint-venture and foreign-invested enterprise have become our static customers both at home and aboard for the present.

Q:What is the filtration accuracy of 50nm ceramic membrane?: The filtration accuracy is the maximum particle size that the membrane can pass through.

Q:Excuse me, what's the reason that all ceramic filters do not attract ore?: After the joint cleaning, 0~2 hours of suction effect may be good, 2~4 may drop slightly, 4 hours later will become worse and worse, or even suck. This case should first check the backwash water pressure (instantaneous maximum pressure should not be less than 0.08MPa) is to meet the requirements, should also advance down (to ensure normal and ultrasonic cleaning combined with nitric acid dosage sufficient) and prolong the cleaning time.

Q:How can I avoid the backwash pressure in the production of ceramic filter?: The backwashing system of ceramic filter is usually made up of water inlet, water inlet, pressure gauge, water filter and filtered water pressure gauge, and then connected to the inside of ceramic filter. Such as the discovery of ceramic filter recoil pressure became smaller or even no recoil pressure, you can carefully observe the surface of the ceramic filter plate is wet or ceramic filter plate wear without water injection at the discharge point, investigation and the reasons for the following aspects:Is the water inlet pressure or normal?How about the sealing performance of the water filter? Does the filter element need to be replaced?Is the recoil system piping (metal pipe, ceramic filter plate, connecting pipe, etc.) broken, leaking or dripping?Is the distributor valve properly installed and is it worn?Are there any cracks in the ceramic filter plate?Is the pressure gauge broken?The most likely reason is 1, 2, two, the best water should not be too dirty, filter should be replaced regularly. I hope the answer can help you.

Q:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?: The spindle speed is too fast.The speed is too high to absorb the filter cake.There are other possible reasons.

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:What happens when the pressure on the filter plate is uneven during backwashing?: Ceramic filter is a kind of solid-liquid separation, dehydration drying equipment, such as dehydration pulp, mortar. The backwash of ceramic filter is to flush the filter medium (ceramic filter plate) with clean water with a certain pressure.

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 are the materials that make up the ceramic mold?: At present, the commercialized porous ceramic membranes are mainly composed of 3 types: flat plate, tubular and multi channel. Flat film is mainly used for small-scale industrial production and laboratory research. The tubular membrane is combined with rice to form a heat exchanger similar to a column tube heat exchanger, which can increase the loading capacity of the membrane, but is gradually withdrawn from industrial application due to its strength problem. The size of the applied ceramic membrane usually adopts a multi channel configuration, that is, a plurality of channels are distributed on a circular cross-section, and the number of general channels is 7, 19 and 37. The main business of the inorganic ceramic membrane preparation technology: using solid particle sintering preparation carrier and microfiltration membrane by sol-gel method in the preparation of ultrafiltration membrane: glass membrane by phase separation method: using special technology (such as chemical vapor deposition, electroless plating, etc.) the preparation of microporous membrane or dense membrane. Its basic theory involves colloid and surface chemistry, material chemistry, solid state ion science, material processing and so on.

Q:Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems: Selection of new ceramic filter plate:Because of the different size and characteristics of the pulp, different users need ceramic filter plates with different pore sizes (i.e., the average range of their surface pore size). In order to avoid the possibility of plugging, ceramic filter plates with suitable aperture range of different manufacturers can be selected.

Q:Performance advantages of ceramic filter: A ceramic filter for fine coal mud recovery, there is a base, the lower part of the frame is provided with a fine slime liquid trough, the fine slime liquid material groove is provided with a liquid level controller, the slime liquid material at both ends of the groove is provided with a negative pressure water tank, the water tank is provided with a negative pressure suction connection assembly fixing the other side is provided with a vacuum pump pipeline, the pipeline is communicated with a vacuum pump and vacuum pump;
