quantitative type 80GSM filter paper for general filteration in laboratory

1.Brief introduction of quantitative type 80GSM filter paper:

Most of the filter paper from the cotton fiber composition, according to different uses and use different methods of production. Because of its material is made of fiber, so its surface has numerous holes for liquid particles through, and the larger particles can not pass through. This property allows the mixing of liquid and solid substances together.

Our filter paper is made of virgin wood pulp, has many size to meet customer desired and we supply the customized service to meet different specification requirement.

The filter paper is suitable for filering in lab, oil factory, coffee, tea, juice, wine and other need filtering industrial.

2.Chromatography of quantitative type 80GSM filter paper:

Paper chromatography is based on filter paper as an inert support. Filter fiber and water have a strong affinity, can absorb about 22% of the water,and 6 to 7% of the water in the form of hydrogen bonds and cellulose hydroxyl combination, under the general conditions more difficult to take off, and filter paper fiber And the organic solvent affinity is very weak, so the general paper chromatography is actually a combination of filter paper fiber as a stationary phase to organic solvent as the mobile phase, when the mobile phase along the paper through the sample, the sample point of solute in the water and The organic phase is continuously distributed, and part of the sample moves with the mobile phase, into the non-solute zone, and then reallocated, part of the solute from the mobile phase into the stationary phase (water phase). As the mobile phase moves continuously, the various parts are continuously distributed according to their respective distribution coefficients and moved along the mobile phase, allowing the material to be separated and purified.

Filter Paper (Filter Paper) is a common chemical laboratory filter tool, the common shape is round, mostly made of cotton fiber.

3:The main species of quantitative type 80GSM filter paper:

Filter paper can be divided into qualitative and quantitative two. In the application of analytical chemistry, when the inorganic compound is filtered to separate the precipitate, the residue collected on the filter paper can be used to calculate the wastage rate during the experiment. Qualitative filter paper, after filtering, has more cotton fiber, it is only suitable for qualitative analysis; quantitative filter paper, especially gray-free filter paper through a special treatment procedures,can more effectively resist the chemical reaction, so the generated Less impurities, can be used for quantitative analysis. In addition to the general laboratory application of filter paper, life and engineering on the application of a lot of filter paper. Coffee filter paper is one of the widely used filter paper, tea bag outside the filter paper provides a high softness and high wet strength characteristics. Other air filter paper that uses suspended particles in the test air, and fiber filters on different industrial applications.

4.Basic nature of quantitative type 80GSM filter paper:

Choosing the right filter paper can be determined by considering the following four factors.

Hardness: filter paper will become wet when filtering, some long-term filtration of the experimental steps should consider the use of wet water after the more tough filter paper.

Filtration efficiency: the density and size of the seepage hole on the filter paper affect its filtration efficiency. High efficiency filter paper filter speed is fast, and the resolution is also high.

Capacity: the accumulation of solid particles in the filter or will block the holes in the filter paper, so the more dense water hole, it means that the higher the capacity, allowing the filter to filter more.

Applicability: Some filter paper is made using special production steps, such as in the test medicine used to determine the blood nitrogen content, must use nitrogen-free filter paper and so on.

Note that filter paper can not filter zinc chloride, otherwise the filter paper will be damaged by corrosion of zinc chloride

7.Selection factor of quantitative type 80GSM filter paper:

In the selection of filter paper should be the main consideration:

1,the effective area, that is, the use of large area filter paper, dust capacity is large, the resistance is small, long life, of course, the corresponding increase in the cost.

2,the fiber diameter fiber diameter is finer, the better the interception effect, the corresponding higher filtration efficiency.

3,the binder content in the binder content of high binder, paper tensile strength is high, the filtration efficiency is high, hair loss phenomenon is small, the filter background dust small, good resistance, but the corresponding increase in resistance.
