Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is suitable for applications that utilize the form and properties of wood pulp, such as water-based electrical material additives and filter aids, and can be stored by adjusting the moisture content and crushed OS degree. The package K11H is sealed in a bag made of impermeable material F.・ Conventionally, asbestos or crushed dried wood pulp has been added to water-based paints and high-thickness coating materials for architectural walls to give a three-dimensional effect to the paint film or to prevent cracks. Ru.

Also, water and other liquid application aids (for F material precoating or
[For body feed] Similar to K, many materials are used.

In the above-mentioned applications, in the case of wood pulp, it is necessary to first disintegrate and disperse it into a container when it is added to the object.

The most common packaging for wood pulp products is a dried sheet with a moisture content of 7 to 10. Hard i-sheets with size 60 scratches x 80 scratches are stacked and packaged in nine pieces, each weighing approximately 2.
00 kg. If this product is to be used for the purposes mentioned above, it is necessary to newly install equipment for disintegrating and crushing the sheets since the amount used per time is small. Another method is to use a large amount of water to defibrate and disperse the sheet in water, but this is often difficult in practice.
It is impossible to implement, and in reality it is almost never used in the form of a sheath.

For this reason, dry valve seats are pulverized using a large amount of power and made into fluff before use. Since this product is in a dry state, there is no need to worry about it rotting during mold growth.The disadvantages are that it is cotton-like and has a small apparent specific gravity, and is bulky, which increases transportation costs, and that it generates a lot of dust when used. have/have.

As a result of repeated research into a pulp packaging form suitable for the above-mentioned uses, the present inventors have overcome the drawbacks of crushed dried pulp stems, and have found that pulp slurry can be appropriately dehydrated, then coarsely crushed. Then, by sealing it in a moisture-impermeable bag, a satisfactory result can be obtained.

Bleached wood pulp is the most preferable pulp slurry that can be used in the present invention, but depending on the use, unbleached, semi-bleached,
It is also possible to use wood pulp free or redisintegrated waste paper such as newspaper.

Furthermore, according to the present invention, pulp keratinizes when water evaporates and dries, so this problem has been prevented. The present invention is also applicable to pulp that has been beaten with a beater to fibrillate the fibers.The beaten pulp of the present invention has a particularly great effect on preventing cracks in coating materials because the fibers are tightly intertwined after drying. - It also has features such as a high ability to separate fine substances into a collecting furnace.

There are various methods for removing excess water from pulp slurry, but preferred is a μ-type dehydration method that does not harden the pulp excessively, such as centrifugal dehydration or V press. Methods such as using a compressor are not very good.

The moisture content after dehydration is preferably as low as possible from the perspective of transportation costs, but
In consideration of self-dispersion, the range should be 50 to 8516. Further, regarding the form after dehydration, it is necessary to have a diameter of 550-4R- or less, preferably 20-4R- or less, from the viewpoint of dispersibility during use. - It is best to crush the carcass into pieces with the following diameter. Large chunks must be made smaller using a rotating blade, etc.

If the product requires long-term storage, it is necessary to add a fungicide or preservative to prevent deterioration due to mold growth or decay. It goes without saying that a commercially available so-called slime run roll agent can be effectively used for this purpose, but it is particularly effective to add a small amount of sodium hypochlorite. Painful residual effective chlorine is 0.2-5P%
It is preferable to add an amount of 0.2pp+n.
If it is less than -, it is difficult to obtain the desired effect <, 5P%! If it exceeds the molecular weight of the cell, the molecular weight of the cell will decrease and the object of use will be adversely affected.

The crushed water-containing pulp obtained as described in detail above does not dry out during storage, and is made into a water-impermeable container immediately after preparation. (bag) is filled and sealed.

Bags made of synthetic resin films such as polyethylene, polypropylene, polyvinyl chloride, nylon, and polyester are suitable as moisture-impermeable containers because they are easy to handle.

EXAMPLES The present invention will be specifically explained below with reference to Examples, but the scope of the present invention is of course not limited by the Examples.

Example 1 A water-dispersed slurry of wood pulp immediately after cooking and bleaching was dehydrated using a tV press to obtain a water-wet pulp mass having a pulp concentration of 30%. This material was crushed using a crushing bar to a size of 20 Faushima or less in diameter.

This material was added and mixed to an aqueous emulsion thick spray paint having the composition shown below.

Reference example BKP (bleached sulfate pulp) product sheet 2 types (moisture 8- and 20G)? A paint was prepared by stirring and mixing using the paint dissolving device of Example 1. The dispersion state of pulp in this paint is shown in Table 1.

Example 2 Bleached wood pulp was beaten with a beater, and sodium hypochlorite was added to give it a 7-leanness. After that, it was dehydrated with a press, and after the water-containing pulp had a concentration of 619I, it was placed in a bag made of polyethylene film. I put it in, sealed it up, and left it at 20°C for 6 months, but there was no mold or rot. After standing for 7 t, the water-containing pulp was redispersed in water, and the firmness was measured at 560-1, with almost no difference compared to before standing. Further, Table 1 shows the properties of this paint when it was made into a paint with the same composition as Gold Example 1.

@1. Residual chlorine is shown using the orthotolidine method (colorimetric method).

Example 3 A bleached sulfate pulp slurry immediately after production was centrifugally dehydrated to obtain a water-containing pulp mass having a pulp density of 35 fh.

This is coarsely crushed into four stages of diameters of 10 or less, 20 or less, 30 or less, and 50 or less to produce a paint with the same composition as Example 1. Its properties are shown in Table 1.
