How to distinguish the quality of high-efficiency filter glue

High-efficiency filter glueis a two-component polyurethane with fast curing, high hardness and high adhesionabglue, which acts between the filter paper and the metal frame of the high-efficiency filter to bond it. Sealing and filling functions. SoHow to distinguish the quality of high-efficiency filter glue? Woolen cloth? Next, I will introduce it to you.

1. Look at the liquidity. High-quality filter glue has a low mixing viscosity and good fluidity, and can easily flow from one end of the aluminum frame to the other, which facilitates construction and saves time and glue consumption; while inferior filter glue has a high mixing viscosity, poor glue fluidity, and even It is impossible to flow from one end of the filter paper to the other end, which greatly increases the construction cost.

2. Look at the bonding strength. High-quality filter glue has strong adhesion after curing and can effectively fix the filter paper and metal frame; while inferior filter glue has poor adhesion and can easily separate the filter paper and metal frame after curing, even causing serious damage. It will fall off naturally.

3. Smell the smell. High-quality filter glue passes SGSand ROHS Certification, no irritating smell, green and environmentally friendly, no harm to the environment and human body; inferior products have a strong irritating smell, and there is no relevant environmental protection certification. Since we produce high-efficiency filters for purification Of course, the raw materials chosen must be environmentally friendly and harmless.

4. Look at the hardness, high quality Filter glue has a high hardness after curing and will not deform; inferior filter glue has a very low hardness after curing, even like an eraser, and will deform with a light touch. Filters made with such glue are not acceptable.

5. Look at the surface and color. The sample block made from high-quality filter glue is white in color, has a smooth surface without bubbles, and has a good gloss, and looks good with the white filter paper; the inferior filter glue is dark yellow in color, has a dull luster, and may even have pitting on the surface. Or bubbles, which are ugly and lack of aesthetics.

6. Look at the settlement. You can observe the settlement of the glue main agent. High-quality glue has less settling and moderate filler; while for inferior products, the main agent settles seriously, and excessive filler is added in order to blindly reduce costs, resulting in increased waste and poor product quality.

Inferior quality high-efficiency filter glue is mostly caused by manufacturers choosing inferior raw materials to produce in order to reduce costs and occupy the market at low prices, or blindly add a large amount of Caused by inferior fillers. This kind of glue must not be used, otherwise it will really be like picking up the seeds and losing the watermelon, and the gain outweighs the loss. The author recommends that you choose to cooperate with high-quality, guaranteed products from manufacturers, such as Shanghai Weigu.

As for how to distinguish the quality of high-efficiency filter glue, the author will introduce it to you here. I hope it can be helpful to everyone. If you want to know more about filter glue, you can follow the author.
