Specifications

various density and thickness
used for industrial furnace and the sealing and insulating material of expanded gaps of furnace

Description

CNBM 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:Does the ceramic factory use hydrochloric acid?
For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate. (do not recommend sulphuric acid)
Q:What is the working pressure of the ceramic filter?
Generally speaking, there are two kinds of working pressure of ceramic filter: vacuum pressure and reverse flushing pressure.
Q:How much is the accuracy of 50nm ceramic membrane filtration?
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:Why does not the iron filter of the ceramic filter work?
The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.
Q:Is the filter plate of the ceramic filter afraid of freezing?
In addition, the temperature is one of the factors affecting the filter suction effect of ceramic filter. The lower the temperature, the worse the suction effect.Therefore, the ceramic filter plate, especially the ceramic filter plate after use, should be protected under low temperature environment.
Q:Common troubles of ceramic filter
The metering pump is not working properly and backwash water into the bucket of acid. The main reason is that the metering pump is not switched on, the diaphragm is worn out, the frequency is too low, and the check valve of the acid pipe and backwash pipe is worn out.
Q:Ceramic filter suddenly do not smoke, a little later on their own good, what reason?
The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
Q:Why should filter core be used in backwash of ceramic filter?
Ceramic filter recoil stage is with certain pressure of clean water from the inside out washing ceramic filter plate, the outer aperture ceramic filter plate from inside is gradually reduced, such as flushing water and unclean inside contain impurities that may block ceramic filter board, other structures in the recoil stage of pollution. Such as recoil, water is not clean, you must go through the water filter cartridge to filter again, the choice of filter core, the higher the accuracy of filtration, the more clean water, but the filter is more likely to plug, scrap. Of course, the water is clean and contains little solids. The filter core is not easy to plug and even water filters can be removed.
Q:The use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
As everyone knows, ceramic filter medium is a ceramic filter plate, microporous ceramic filter plate with a lot of distribution from the outside to the inside capillary effect, its mechanism is based on the capillary effect of microporous ceramic filter, filtration, the filtrate (generally refers to water) through these pores under the action of the vacuum suction pump, filter cake is trapped on the surface of the ceramic filter plate.
Q:The ceramic filter suddenly did not smoke, and later he was all right. What's the reason?
The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.
