Chemical experiment treatment: extract the bag samples, using the professional instrument laboratory detection filter filter bag oil composition, to adapt to washing raw materials, the maximum cleaning filter bag and without causing any damage to the filter bag.
Q:How is the filter material processed by the filter bag?
The second is heat finalization to ensure the stability of the chemical fiber filter, to maintain the reliable work of the dust collector, and to deal with the heat finalization of the filter material. It is also that hot melt pressure processing can increase the density of the needle felt, make the surface pore smaller, the fuzz is hot, smooth and smooth
Q:How do garbage bags in washing machines have no garbage
That's because when you wash your clothes the water level is too low, the water can't come up, so you can't filter the water, you can adjust the water level. And the filter bag doesn't work,
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 are the characteristics of a liquid filter bag?
Chemical etch is good, acid and alkali resistance. The filtration efficiency is high, can reach more than 99.5%
Q:How about the filter bag of the washing machine
