Description

Предлагаемый способ получени  концентрированного латекса из наших мелких каучуконосных растений может быть легко осуществлен и механизирован , дава  возможность иметь отечественный натуральный латекс.The proposed method of obtaining concentrated latex from our small rubber plants can be easily implemented and mechanized, making it possible to have domestic natural latex.

Способ осуществл етс  следующей производственной схемой: Копка корнейThe method is carried out by the following production scheme: Digging the roots

I Удаление ботвыI Remove tops

I Замочка корней в холодной воде (2-24 ч.)I Lock the roots in cold water (2-24 hours)

Измельчение корней   отмывкз в среде, состо щей из консервирующих, поверхностно прочных и поверхностно активных веществGrinding the roots of washing off in an environment consisting of preservative, surface strong and surface active substances

I Отжим латекса от корней на центрсфутеI Spin latex from roots on centresfute

Простое отс1аивание латекса от загр зн ющих веществ или отделение на центрофугах сепараторахSimple removal of latex from contaminants or separation on centrifugal separators

I Добавка защитных веществI Addition of protective substances

I Сепарирование 1-еI Separation 1st

I Сепарирование 2-еI Separation 2nd

I Сепарирование 3-еI Separation 3rd

При этом:Wherein:

1.Корни копаютс  в любой период вегетации, но лучще осенью.1. Roots digging in any growing season, but better in the fall.

2.Удал ют ботву на 1-2 мм выше корневой шейки.2. Removed the tops of the tops 1-2 mm above the root collar.

3.Замачивают в холодной воде 2-24 часа, лучше в проточной воде.3. Zamachivat in cold water for 2-24 hours, preferably in running water.

4.Отмывают гр зь от корней холодной водой на обычных кулачковых мойках.4. Wash the soil from the roots with cold water on ordinary cam washers.

5.Корни измельчаютс  на резальных или на иных аппаратах в присутствии среды, предохран ющей от коагул ции. Эта среда составл етс  из защитных коллоидов и консервирующих веществ, а именно:5. The roots are crushed on cutting or on other devices in the presence of a medium that prevents coagulation. This medium is composed of protective colloids and preservatives, namely:

Пример 1 Пример 2 Пример 3Example 1 Example 2 Example 3

0,5 ам.миака 0,1 декстрина 0,05 Сйпонина0.5 ammonia 0.1 dextrin 0.05 Siponin

Без введени  указанных веществ получаетс  меньще латекса и он легко переходит в коагулированную форму.Without the introduction of these substances, less latex is obtained and it is easily converted to coagulated form.

При из.чельчании необходимо стремитьс  делать очень тонкие срезы.When chopping, it is necessary to make very thin sections.

Изрезанные корни отмываютс  от латекса перемешиванием в кулачковой мещалке, спаренной с резальным аппаратом в одно целое.Rugged roots are washed from latex by mixing in a cam bristle paired with the cutter in one piece.

Осуществл   измельчение в защитной среде, кулачковое приспособление с элеватором осуи1,ествл ет и вымывание и неп.рерызное удаление резаных корней.Having performed grinding in a protective environment, the cam attachment with the axle-type elevator1, eliminates both the leaching and the non-cutting removal of the cut roots.

Дл  того, чтобы получить латекс не ниже 1,5% концентрации, необходимо через промывочную жидкость несколько раз пропустить свеже измельченные корни.In order to obtain a latex of at least 1.5% concentration, it is necessary to pass freshly chopped roots through the washing liquid several times.

Полученный латекс еще не имеет технической ценности дл  резиновых заводов в силу концентрации 1,5-4°/о (по каучуку). В ходе дальнейшей обработки его сначала отстаивают от гр зи. Вместо простого отстаивани  можно гр зь удал ть на центрофуге-сепараторе . Затем подвергают латекс низкой концентрации троекратной повторной сепарации, после чего получают его совершенно белым с содержанием каучука и выше. Перед концентрированием на сепараторе добавл ютс  защитные коллоиды (казеинат аммони  и олениат аммони  и др.).The obtained latex does not yet have a technical value for rubber plants due to the concentration of 1.5-4 ° / o (for rubber). During further processing, it is first defended from dirt. Instead of simply settling, the dirt can be removed at the centrifugal separator. The latex is then subjected to a low concentration three times of repeated separation, after which it is obtained completely white with a rubber content and higher. Before concentrating on the separator, protective colloids (ammonium caseinate and ammonium deer and others) are added.

При прибавлении слабых и крепких кислот латекс коагулирует. При обмакивании в него предметов оставл ет слой, который при подсыхании дает эластичную пленку.With the addition of weak and strong acids, latex coagulates. When dipping objects into it, it leaves a layer that, when dried, produces an elastic film.

Предмет изобретени .The subject matter of the invention.

Способ приготовлени  латекса на каучуконосов, например, кок-тау и крым-сагизов, отличающийс  тем, что отмытые и измельченные корни указанных каучуконосов обрабатывают водой, содержащей консервирующие веш,ества, защитные коллоиды и диспергаторы (например, щелочи и щелочные СОЛИ; белковые вещества, углеводы, альгинаты, сапонин, мыльный корень, олеиновую и стеариновые кислоты), после чего полученныйлатекс обогащают и концентрируют известны.ми методами центрофугировани  и сепарации.The method of preparing latex on rubber, for example, Kok-Tau and Crimea-Sagiz, characterized in that the washed and shredded roots of these rubber plants are treated with water containing preservative substances, protective colloids and dispersants (for example, alkalis and alkaline SALT; protein substances, carbohydrates, alginates, saponin, soap root, oleic and stearic acids), after which the resulting latex is enriched and concentrated using known centrifuging and separation methods.
