Q:Please tell me where the filter bags are sold in the washer.
The filter is sold after sale. But quite expensive.I hope my answer will help you.
Q:How do you use a filter bag?
In order to improve the use of filter bags, we should pay special attention to this knowledge in ordinary times. If we have different problems, we need to find solutions. First, the bag is broken. The shape of the filter bag and the installation method of the filter bag determine the location of the filter bag easily broken, which can be inspected and repaired. Secondly, the filter bags age. For reasons that are caused by the following reasons, reasons should be investigated, taking the elimination measures and changing the filter bags. (1) hardening and contracting due to unusually high temperature; (2) due to contact with the vapor of an acid, alkali or organic solvent; 3) react with water.
Q:What is the quality inspection of the filter bag?
The instrument is used to test the filter bag after cleaning, to ensure the quality of cleaning is met. Through the processing of the above process, the cleaning bag can meet the requirement
Q:How is the filter bag type and filtration efficiency
In the process of preparing adhesive can contain a large number of particles, the particles including segments of unreacted fibers, organic resin, gel particles, half fiber and chelation of inorganic matter, organic particles, metal, crystal, inorganic particles and ash, rust and other impurities.
Q:What is a good filter bag?
However, the loop suture of the filter bag can be a single line, but it needs to be sewn more than two times.
Q:What are the textures of the liquid filter bag
Nylon mesh (NMO) : nylon mesh, also known as nylon mesh, nylon mesh, nylon mesh, is made by nylon 6 (PA6) monofilament through flexible rapier loom plain weaving, dyeing (if needed), heat setting process. Made of synthetic fibres, it is a polyamide system.
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:What is the cause of the liquid filter bag
Accident and material problems: filter bag when installation is not correct, improper use or operators, and there are defects will filter bag filter design problem, the other material choice can no more harm the filter bag use.
Q:Who has used a liquid filter bag? What is its feature?
The filtration efficiency is high, can reach more than 99.5% Expanding filter cloth (bag), improving filter wind speed and filtration efficiency, reducing the volume of dust removal equipment
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.
