Description
В насто щее врем при разработке рабочих чергеж-ей расходуетс большое количество чертежной бумаги, ютсра после однократного ее испОиПьзовани идет в отход.At present, when designing workers, a large amount of drawing paper is consumed; after the one-time use of the drawing paper, the waste is discarded.
Описываемый способ устр ан ет у1:азанный Не,до-статак и обеспечивает возможность получени чертежной бумаги дл многократного ее использовани .The described method arranges y1: Hexane He, to-statak and provides the possibility of obtaining drawing paper for its multiple use.
Отличие предлагаемого способа от известных заключаетс в том, что бумагу пропитывают 5%-пым раствором целлофана шш иного прозрачного слабо-горючего пласт1иката в соответствуюилем растворителе. Дл повторного иcпoльзoзaн;i полученной (пропьтанмой) бумапикара дашные линии 1С1МЫвают с помощью растворител или 10%-ного раствора ст1ирального порошка. Дл приготсьлени раствора пластиката oicпользуют отходы деталей или стружки, получающиес при изготовлении различных изделий из указанного пластиката.The distinction of the proposed method from the known ones is that the paper is impregnated with a 5% solution of cellophane or another transparent low-flammable plasticate in the appropriate solvent. For repeated use, i obtained (by using) paper paper Dash lines 1C1 are washed with a solvent or a 10% aqueous solution of sterile powder. To prepare oic plasticate solution, waste parts or chips, which are produced in the manufacture of various products from the specified plasticate, are used.
Примерна схема получени чертежной бумаги по описываемому способу: бумага с рулона поступает в ванну, наполвденг ую 5%-ным раствором пластиката, затем проходит через оущильную камеру и на1матыва-етс на барабан.An exemplary scheme for the preparation of drawing paper according to the described method: paper from a roll enters the bath with a full 5% solution of plastic compound, then passes through the drying chamber and winds onto the drum.
Получанна таким образом бумага употребл етс дл многократного , примерно, до 3-6 раз использовани .The paper produced in this way is consumed for repeated use, approximately up to 3-6 times.
