PROCEDURE AND ADDITIVE FOR PREVENTING
CLOGGING OF A HANDLING PROCESS
ABSTRACT OF DISCLOSURE
A procedure for preventing clogging of a pro-
cess handling dry cellulose-containing material,
antistatic agent being added into the process.
An additive for use in connection with a dry
cellulosic material handling process said additive
being an antistatic agent.


Claims

Note: Claims are shown in the official language in which they were submitted.


12
CLAIMS
1. A procedure for preventing clogging of a
process handling mainly dry cellulose-containing mate-
rial and for improving the handling properties of the
material, characterized in that antistatic agent is
added to the cellulosic material.
2. Procedure according to claim 1, character-
ized in that antistatio agent is sprayed into a dry
handling process, seleoted from the group: grinder feed
means, grinder, conveyor, screen, and fibre web forming
process.
3. Procedure according to claim 1 or 2, char-
acterized in that antistatic agent is supplied onto the
cellulose particles to be ground.
4. Procedure according to any one of claims
1-3, characterized in that the antistatic agent is
liquid and contains water and antistatic chemical 1 to
29%, and additive selected from the groups: ethanol 2
to 40% and glycol 1 to 10%.
5. Additive for use in connection with a pro-
cess handling mainly dry cellulosic material, in order
to prevent clogging of the process and to in prove the
handling properties of the material, characterized in
that the additive is an antistatic agent.
6. additive according to claim 5, character-
ized in that the additive contains water and antistatic
chemical 1 to 20%.
7. Additive according to claim 5 or 6, char-
acterized in that the additive contains ethanol 2 to
40%.

Regarding the features which are characterist-
ic o~ ~che inven~ion, reference ~ made ~o t31e ~laim~

agen~.
An$is~afic agen~ can be added e.g. ~y spraying
it on the ma~e~ial to ~e ~reat2d, ~uch as e.g. ~n c~1-

The anti6~a~i~ agent i~ uid or gaseous, and
i~ contains a~Y~n~ageou~ly, in addition ~o an anti~at-
~c ~Pmi~al, as carrier subs~ance ~. water, propor-
~ion of anti~tic chemical e~g. ~ tc 20~, ~ui~able 4to 16%. T~e anti~tati~ agent may furthermore contain
e.g. ethanol (possibly qen~Nred~ or another al~ohol,
e~g. 2 to 4Q%, adv2~geo~ly 5 ~o 30~. Fuxthermore~
~he anti~tatic agent may oontain e.g. glycol, ~uc~ as

~he a~ tatic agent ~ay be anionic, c~tionic
or ~on-ionic. ~he following may ~ mentio~ed as ex~-
ples: poly3mlnes, quaternary ~itrogen co~pounds, ~l~yl
aimethyl-ben2ylammonium halides, e.g. chlorides.
All perc~n~ages ax~ ~xpressed a~ ~ by weigh~.
Thank~ ~o the inve~ion, and by i~ aid, it
h~ ~een poss~le to prevent mo~ efflciently the clog
ging of ~he cellulose grLndL~g process mainly in con-
neGtion w~h the grin~ing of dry cellulo~ or
