Q:What kind of bag is used in the food industry
It depends on how he USES it, what he used to make, how he used it, and what problems he found! It's better to make a judgment! Welcome!
Q:What is the reason for the strong drop in the broken filter bag of the cement mill dust filter bag
There are several reasons for the failure of dust filter bags: A, burning. High temperature burning is the main reason of the flue gas temperature over the filter bag to allow maximum limit temperature even in flue gas with a flame, intuitive performance for the filter bag melted coking or hole. Second, the corrosion. Cloth bag dust catcher by the corrosion damage of the most obvious characteristics of filter bag in the strength of the whole, main show is in the coal-fired power plant flue gas dust removal of acid corrosion and oxidation corrosion lead to filter bag can withstand load, such as to lose filtering performance and failure.
Q:How to check the filter bag and the dust collector bag when the dust collector is installed?
Installation of bag filter bag quality inspection is also more important, with the bag cage check: because of the bag filter to board, cooperation between the bag and the bag cage requirements is very high, so when installing the bag cage must strictly control the space between the cage with a bag, bag to fit clearance beyond the technical requirements of replacement at once. Finally after installation of the re-inspection, the bag cage after installation, for all the bag cage installation, check one by one, the quality of the installation, review the top of the bag cage with the bag mouth and bag cage, stable performance.
Q:Please tell me where the filter bags are sold in the washer.
The filter bag is broken, the average border is good, and you can make it yourself: you can cut it up and cut it into a bag that is the size of the right size, so you can stick it to the border.
Q:How is the filter material processed by the filter bag?
Finally is chemical treatment to improve the filter material, especially the dust filtering performance and the strength of glass fiber filter material, heat resistant, flame retardant, corrosion resistant performance, are of great significance.
Q:How to choose a liquid filter bag
1, first of all, according to the chemical name to filter the fluid, according to the chemical with taboo to find available filter material, commonly used in PE, PP, PTFE, NMO, again according to its operating temperature, operating pressure, ph, operating conditions (such as whether to need to tolerate steam, hot water or chemical sterilization, etc.), assessed and eliminate shall not apply to the filter material. Use is also an important consideration, such as pharmaceutical, food or cosmetic ingredients that must be approved by the FDA; Ultra-pure water should be chosen for pure and not contain the filter material that will affect the impedance. Filter gases should be selected for hydrophobic materials and whether "health grade filtering" design is required. The main foreign Filter bags are GAF, FSI, 3M, CUNO, U.S. Filter, LOEFFLER, PARK, Vablue Filter bag etc
Q:What are the textures of the liquid filter bag
Nylon net has high strength, wear resistance, chemical resistance, water resistance, flexibility is good, because the wire diameter uniformity, smooth surface, so the ink through sex is also very good. It is not very stretchable by nylon. This kind of screen is in a period of time after the stretch net, the tension is reduced, make the screen plate is relaxed, the precision is reduced. Therefore, it is not suitable for the printed circuit board and so on.
Q:Filtration efficiency of liquid filtration bag
Absolute filter: filter is absolutely intercept surface filtering method, is greater than a certain size particles of 95-99.9% were intercepted, less than the size of the particles by all. Pore size must be same size on the surface of the filter bag material, weave fabric must be tight and firm, material requirements after joint can bear high pressure, can prevent leakage occurs, absolute filtering effect can be assured.
Q:Whether the washing machine filter bag is damaged or not
It doesn't affect the filter bag that can only filter the washing in a wash bucket
Q:How to remove the washer filter bag
The non-specialist mistakenly dismounted the machine, It's best to find a knowledgeable or professional person, or sell it later to help!
