Description

The invention aims to produce a so-called eternal match multiple use.

The essence of the invention is that a rod of combustible, highly flammable mass is surrounded by a thin layer of red phosphorus, and then enveloped with a non-burning layer. For firing, there is a friction plane, containing potassium chlorate.

The method is as follows. Ordinary non-glued paper is boiled with sulfuric acid until it loses its fibrous structure and turns into a powdered pulp, which requires a very short period of time. This cellulosic powder is filtered, washed with water until the reaction disappears and then dried.

This pulp powder 46 weight. share, well mixed with 8 wt. parts of powdered paraffin, 22 wt. parts of metaldehyde and, with the help of a solution consisting of 31.6 parts of water, 15.6% of table glue (4-6 glue) is kneaded in a paste).

a shaped mass, from which the rods (sticks) with a diameter of about 3 mm and a length of about c protrude in any way. These sticks are omitted at TeMtiepaType, at about 30 °. ;

After drying the sticks, these are dipped into a phosphoric mass, composed as follows. 45 weight is taken for 100 weight fractions of water. shares of red phosphorus, 20 wt. a share of n-grained antimony, 15 wt. fractions of glass powder, 10 wt. Meta, 9.5 wt. a share of midi glue and 0.5 weight. share of traganta. The sticks dipped in the composition are quickly dried at a temperature of 60-65 ° C, and the finely and evenly distributed paraffin melts in the stick, makes the mass porous and simultaneously impregnates it with paraffin.

Dried and coated sticks are then dipped into the W / o-th solution of table (core) glue, in which 50 wt. Are evenly distributed. a fraction of asbestos powder. After this, the sticks are dried again at low temperature. Sticks are now covered thin

a layer of asbestos that delays unwanted access of air to phosphorus. In order to enhance the water resistance of the sticks, a solution of acetyl cellulose with acetone can be taken instead of a solution of glue. A stick of normal size can reach 180-200 ignitions. Plum has a beautiful yellow color and burns smoothly without smoke. Plum is easily extinguished by simply blowing or waving a match.

Inflammation occurs by friction sticks on a special friction surface, made as follows: 0.5 wt. share of traganta and b weight. The table glue was diluted in 1000 wt. dol x water. And 40 wt. fractions of potassium chlorate, 15 wt. a fraction of magnetic iron, 5 wt. shares of manganese peroxide and 15 wt. a proportion of glass powder.

This mass is well stirred and applied to a metal sheet at a temperature of about 40 °. After drying, this mass is used as friction surface for ignition.

As a mass production, the manufacture of matches according to this invention can be carried out in a relatively simple and cheap way, and the product has several major advantages over ordinary matches.

In addition, the production is not dangerous in relation to fire or flammability, and is not harmful to health.

The subject matter of the invention.

Way

reusable match making, characterized by

By the fact that some kind of cellulose pulp is taken as a burning inner rod, a layer containing red phosphorus is applied to the core outside, and the latter is covered with a non-combustible layer containing asbestos.
