Description

Известно, что наиболее эффективными гидрофобизаторами дл  древесно-волокнистых изол ционных плит  вл ютс  эмульсии, в составе которых основным компонентом  вл етс  неполностью омыленна  и не растворима  в воде канифоль.It is known that the most effective water repellents for wood-fiber insulation boards are emulsions, in which the main component is incompletely saponified and rosin is not soluble in water.

Способ приготовлени  этих эмульсий трудоемок.The method of preparation of these emulsions is laborious.

Предлагаетс  гидрофобизатор дл  древесно-волокнистых плит из отходов терпентинного производства, процесс изготовлени  которого сводитс  к следующему: в теплоизолированный куб, оборудованный мешалкой и барботером острого пара, загружаетс  отделенный в основном от воды отстой из живичных отстойников, состо щий из смеси примерно 40-50% живицы, 15-20% механических примесей и 30- 40% воды. В куб добавл ют 14-16% каустика в расчете на 100% от содержани  канифоли в отстое и острым наром отгон ют от отсто  скипидар , который можно отгон ть и до момента добавлени  щелочи. Пары воды и скипидара конденсируютс  в холодильнике. Скипидар отгон етс  от воды во флорентине.A water repellent is offered for wood-fiber plates from the waste of the turpentine production, the manufacturing process of which is as follows: a heat-insulated cube equipped with a stirrer and a sparger bubbler is loaded, mainly from water, sludge from animal pits, consisting of a mixture of about 40-50% resin, 15-20% of mechanical impurities and 30-40% of water. 14-16% caustic is added to the cube calculated on the basis of 100% of the rosin content in the sludge and with sharp heft distilled from the sludge turpentine, which can be distilled off before the addition of alkali. Water and turpentine vapor are condensed in the refrigerator. Turpentine is distilled from water in Florentine.

Одновременно с отдувкой скипидара происходит полное омыление канифоли щелочью.Simultaneously with the stripping of turpentine there is a complete saponification of rosin with alkali.

Операции протекают при перемешивании. Остаток после отгонки скипидара в виде подвижной пасты  вл етс  готовым гидрофобизатором , примерно, следующего состава: канифоль - 30-40%, механические примеси - 20-30%, влага - 30-40%, едкий натр (св занный и свободный) - 14-16% от веса канифоли.Operations proceed with stirring. The residue after the distillation of turpentine in the form of a mobile paste is a ready-made water repellent of approximately the following composition: rosin - 30-40%, mechanical impurities - 20-30%, moisture - 30-40%, caustic soda (bound and free) - 14 -16% by weight of rosin.

Новым в предложении  вл етс  применение при изготовлении гидрофобизатора в качестве проклеивающего вещества водного раствора полностью омыленной канифоли.New in the proposal is the use in the manufacture of a water-repellent agent as an sizing agent of an aqueous solution of fully saponified rosin.

Процесс изготовлени  предлагаемого гидрофобизатора значительно проще, так как исключаютс  предварительна  варка кле  и приготовление эмульсии, которые имеют место при изготовлении известных гидрофобизаторов на основе канифоли, парафина, петролатума и др. комаонентон.The manufacturing process of the proposed water repellent is much simpler, since the pre-cooking of the adhesive and the preparation of the emulsion, which take place in the manufacture of the known water-repellent based on rosin, paraffin, petrolatum, etc., are excluded.

Гидрофобизатор иримен етс  при дес тикратном растворении в, аоде путем введени  в, метальный бассейн с древесной массой.The water repellent is designed to be dissolved ten times in the aod by introducing into the metal pool with wood pulp.

Предложенный гидрофобизатор был подвергнут производственным испытани м в течение 13-ти смен в цехе древесно-волокнистых плит Ново-Л линского ЦБК.The proposed water-repellent agent was subjected to production tests during 13 shifts in the wood-fiber board workshop of the Novo-Linsk pulp and paper mill.

Результаты испытаний сведены в таблицу:The test results are summarized in the table:

Из таблицы видио, что водопоглощение плит во всех сери х исны::аиий составл ет величины меньше допускаемого иоедела по ГОСТу (по ГОСТу - 20 % ).From the table of videos that the water absorption of the plates in all series of isna :: aii is less than the allowable amount of the week according to GOST (20% according to GOST).

Все остальные показатели отг ечают требовани м ГОСТа..All other indicators meet the requirements of GOST.
