get the products at your country.

3) What is your terms of delivery?

We accept EXW, FOB, CIF, etc. You can choose the one which is the most convenient or cost effective for you.

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: Why is the filter bag material PE a polyester, not a polyethylene: It is divided into high density polyethylene, medium density polyethylene and low density polyethylene according to the density. Polyethylene is a high polymer chain that is connected by a repeat - CH2 - unit connection through the addition and polymerization of ethylene (CH2 = CH2). Purpose: polyethylene insoluble in water, water is very small, is about some chemical solvents, such as toluene, acetic acid, etc., and only showing modest dissolved when temperature above 70 ℃. But polyethylene particles shape, can be between 15 ℃ and 40 ℃ melting or solidification, along with the change of temperature at higher temperatures melt, absorbing heat; When the temperature drops, it solidifies, releasing heat. Because it absorbs little water, it is not wet, it has insulation, so it is a good building material.

Q: What is the filter principle of the high performance filter bag?: The network structure of nanofibers can reduce the thickness and line density of the supporting filter, thus reducing the pressure loss and improving the efficiency of production.

Q: The filter bag in the washing machine is broken. How do you fix it: The filter bag in the washer is broken, the maintenance method is replacement, the replacement step: 1, use a screwdriver to remove all the screws. 2, remove the back cover. 3, remove the filter bag from the inside and outside barrels. 4, install the paste card slot. 5 will filter the network card. 6, cover the cover and screw.

Q: How to choose a liquid filter bag: Filter bag precision options: This is the most troubling question. For example, to remove visible particles, use a 20 or 25 micron filter bag. To remove the cloud from the liquid, use a 1 or 5 micron filter bag. To filter out the smallest bacteria, you need a 0.2 micron filter bag. The problem is that there are two types of filter units: absolute accuracy/nominal accuracy.

Q: How does the filter bag work?: Mechanical vibration wave sootblower is often used in small single cartridge filter, it is the use of filter plate produced by the eccentric gear on shaking power to clear the ash, this action need downtime after operation.

Q: What is the correct way to use a filter bag: Third, the cloth should not hang too loosely or too tightly, too easily to accumulate dust, too close to pull out. Fourth, new process old filter bag should not be mixed, avoid damage time different effect equipment normal work

Q: How can the filter bag be processed later?: Burning pressure processing After burning equipment, processing of needled felt filter material single and double sided with singeing and ordinary pressure light processing incomparable advantages, can not only improve the ash removal performance of the filter, also meet the fine dust collection.

Q: How do you check the filter material of the filter bag?: Special features: the properties of heat resistance, abrasion resistance, flame retardant, antistatic properties, corrosion resistance and hydrophobic properties. Membrane filter: check the membrane strength.
