SU16991A1 - The method of obtaining paper, cardboard and plastic from wood, bark, scraps of paper, waste with grinders - Google Patents

Description

The proposed method is intended for the production of KaipTOHa, paper and plastic from wood, bark, paper scraps, leather, garbage from wood grinders, moss, dry grass, straw, sawdust, etc.

The method consists in that the above substances are well dried / and then and {ground to a dust-like state on the runners. Such DUST c) oceans, as sieves, and sometimes without prior sifting, are added in quantity, starting at 40%, to wood OR the typical mass in rolle to be combined with this mass at ordinary or boiling temperatures. . If the source material is one bark, then it is cut into short pieces and subjected to soaking for a few days. Then the bark is ground on the runners to the desired

Fiber lengths: in this grinding, the crust is divided into very elastic fibers (lower part of the bark adjacent to the tree) and a fluffy mass (from the upper part of the bark). To the ground fat mass in a roll, add dry bark, ground in the form of flour. The resulting homogeneous mass is subjected to sizing with an alcoholic solution of a natural resin (sap) OR rosin. Cardboard OR paper obtained from bark is more dense, flexible and strong and, due to admixture of table salt, is badly hot. For obtaining soft cardboard, such garbage as sawdust and shavings are particularly suitable, after drying, processed on stone or metal runners, rollers, ball mills, etc. machines. In this process, soft dust is obtained in the form of fluff, mixed with wood or wood in a roll with the addition,

 in these cases and without the addition of filling substances, such as: clay, ash, ash, ocher, etc. In order to obtain glued cardboard or paper, prepared from sawdust, the latter are processed, with constant mixing and heating with deaf steam . A kerosene solution of resin and rosin, taken in equal parts. At the same time, to give the resulting product a brown tint and for some compaction, 15-20 o / o of softwood shredded in the dry state of the bark of coniferous trees and the total content of the roll is heated to 60-80 ° to the mass obtained from the sawdust by the above method. In the same kind. garbage from grinders can be reversed: milled on runners to a dusty condition, they are added in an amount of 400/0 and above to; wood pulp in a roll, where the entire mass is subjected to sizing, or, in order to conserve glue, the mass is read by it in its dry form. Materials for obtaining the above-mentioned dusty mass can serve not only wood, bark or cork, but also various plant fiber, such as: straw, moss, reed, storms, deadwood, and all rotten wood. Dust is released in cold water in an apparatus with continuously moving agitators in order to swell it, which is also facilitated by boiling the mass for 1/2 to 2 hours. Powder from the stretch of back fiber is added to the powder and powder from still dry mineral materials such as clay, flour, or crushed potato husks, dried, i.e. dust from flour mills, asbestos, magnesia, chalk, slaked lime, pumice, coal dust, finely: crushed glass, mica, porcelain bat, clay on dishes, etc. The choice of plant fiber or animal fiber, a mixture of other mineral substances, depends on the properties of the final product, mc receive, and receive its processing. So, if you wish to get a softer g / product, you should take a larger percentage of leather leather as a mixture for wood, the more solid the product is

In this combination, if ma (su is heated. The admixture of pumiceum plugs to the mixture reduces the weight of the final product, the admixture of rubbed ocher, especially with the addition of the temple and when i is heated, informs the product non-giurochichnost. For-receiving; a unit of wood and bark (a ratio of 1: 1), add-xy-4o / o, shredded, prepared by bzz mas a. ocher-3 / o by the end of operation-4. o dry boiling salt. Processing in a roll at boiling of the debtor lasts 1 | b for one and a half hours, as a result it receives;
